Date: March 24th, 2025
This source, written by Joachim Bartoll in 2025, reviews a study correlating restricted carbohydrate and seed oil intake during the UK's WWII food rationing with lower rates of chronic diseases later in life. Bartoll argues this "natural experiment" highlights the detrimental effects of sugar and plant-based unsaturated fats on human health. He asserts that humans are obligate hypercarnivores needing primarily animal-based foods and that consuming carbohydrates and seed oils, especially in early life, leads to significant health problems. The author criticizes current dietary recommendations and emphasizes a zero-carbohydrate diet, particularly for children, based on his understanding of biology and physiology. He suggests that the observed lower disease rates during rationing support his views on the dangers of these food groups and the benefits of an animal-based diet. Bartoll concludes by advocating for a lifelong avoidance of plant-based and processed foods and offers his coaching services.
Author's Main Argument: Restricting carbohydrates (sugars and all carbs) and seed/vegetable oils during pregnancy and early childhood is crucial for preventing chronic diseases like type 2 diabetes, hypertension, and obesity later in life. This is based on the author's belief that the natural human diet is animal-based, and that carbohydrates and seed oils are toxic and damaging to human physiology.
Key Themes and Ideas:
Critique of a "Natural Experiment": The author reviews a study that compared disease rates in individuals conceived during and after the UK's food rationing period (1942-1953). This period saw significant restrictions in sugar, fruits, cereals, rice, chocolate, biscuits, and seed/vegetable oils.
The author finds the term "natural experiment" misleading, suggesting the rationing might have been a deliberate act ("World War II Psy-Op") rather than a consequence of scarcity.
He highlights that while some animal products were slightly restricted, the "huge restriction of toxic plant-based garbage, especially carbohydrates and seed oils, contributed to a much lower toxic load on the body."
The Detrimental Effects of Sugar and Carbohydrates: The author argues that all carbohydrates, as they turn into glucose, are damaging to the body when consumed. He cites the increase in sugar intake after rationing ended and the high current sugar and carbohydrate consumption in children as alarming.
"The end of food rationing led to an immediate increase in children’s sugar intake (+50%-60%; approximately 25 grams more) and fat intake (+10%-20%; approximately 6 grams more), which amounts to approximately 160 more total calories consumed per day."
He asserts that humans are "obligate hyper carnivores" who manufacture their own glucose and should consume "ZERO, as in 0 grams carbohydrates a day."
He criticizes current dietary guidelines and statistics on sugar intake, believing they underestimate the problem by not counting all carbohydrates.
The Harmful Nature of Seed/Vegetable Oils (Unsaturated Fats from Plants): The author contends that unsaturated fats from plants are "not chemically compatible with human physiology" and are prone to oxidation and rancidity, causing significant damage.
"Unsaturated fatty acids, characteristic of plant-based foods, are not a part of human physiology."
He explains that the body has to convert these fats, a process that can lead to "toxic residues" and "oxidation."
He emphasizes that the combination of high blood glucose from carbohydrates and the consumption of seed oils exacerbates damage, contributing to atherosclerosis and cardiovascular issues.
The Benefits of the Rationing Period: The author highlights the study's finding that those born during sugar rationing had significantly lower risks of type 2 diabetes, hypertension, and obesity later in life.
"When analyzing the populations decades later (e.g., in their 50s and 60s), the participants who were born during sugar rationing had a 36% lower risk of type 2 diabetes, a 19% lower risk of hypertension, and a 31% lower risk of obesity compared to the participants who were born after sugar rationing ended..."
He attributes these protective effects primarily to the restriction of carbohydrates and seed oils, downplaying the slight restriction of some animal products.
Rejection of "Overnutrition" and Emphasis on Species-Appropriate Diet: The author dismisses the concept of "overnutrition" when it comes to a species-appropriate (animal-based) diet, arguing that the body will simply store or discard excess nutrients.
"'Overnutrition' would be consuming more than you need of actual nutrients, as in your species-appropriate diet of solely animal-based foods. And that would simply be a waste, as your body would store what it could for later use and then discard whatever it can’t use."
He believes that true nutritional problems arise from "overfeeding on toxic species-inappropriate foods" (carbohydrates and seed oils).
Critique of "Calories" and Emphasis on Toxicity: The author states that "calories" are irrelevant to human physiology, as they are a measure of heat, not how the body works. He believes the primary concern is the "toxicity" and damage caused by species-inappropriate foods.
"Calories do not exist as they are a measurement of heat, as in heat units, and that is not how our body works. So, 'calories' are totally irrelevant..."
Essential Role of Animal Fats and Protein: The author posits that only protein and animal fats (including saturated fat and cholesterol, which he deems vital) are essential macronutrients for humans. He claims the body can produce its own glucose and does not require unsaturated fats from plants.
"Based on biological and physiological principles, it is recognized that only protein and fat are essential macronutrients for humans."
"In biology, biochemistry, and physiology, it is well-established that saturated fats and cholesterol are vital components of our cells."
Response to Examine.com's Conclusion: While the author references Examine.com's review of the study, he strongly disagrees with their cautious interpretation and perceived "limited understanding of the underlying mechanism." He asserts that the science is simple: "Crap in equals crap out."
Important Facts and Figures:
The UK food rationing period lasted from 1942 to 1953.
Rationed items included sugar (from January 1940), fruits, cereals, rice, chocolate, biscuits, margarine, jam, cheese, and eggs.
Pregnant mothers and children received double the ration of eggs and more meat.
After rationing ended, children's sugar intake increased by 50-60% (approximately 25 grams more) and fat intake by 10-20% (approximately 6 grams more), totaling about 160 more calories per day.
Individuals born during sugar rationing had a 36% lower risk of type 2 diabetes, a 19% lower risk of hypertension, and a 31% lower risk of obesity in their 50s and 60s compared to those born after.
The estimated mean daily intake of total sugar among preschool-aged children (2014-2016 study) is 86 grams.
Children aged 2 to 5 years in the US (2017/18 NHANES data) consume an average of 220 grams of carbohydrates per day.
Quotes Highlighting Key Arguments:
"This study, although very limited, does bring more evidence to the table of the extreme destructive forces of sugar, as in carbohydrates, and unsaturated fats, as in seed/vegetable oils."
"Humans are meant to run on animal fats as we manufacture our own glucose. Therefore, humans should not consume any carbohydrates at all..."
"Any kind of plant-based unsaturated fat will cause damage in the body."
"There is no such thing as 'overnutrition,' as 'nutrition' is the definition of taking in food and using it for growth, metabolism, and repair... As long as the nutrients are in animal-form, as in fully bioavailable and bioactive, they are non-toxic and can’t cause any damage no matter the quantities."
"Calories do not exist as they are a measurement of heat... The only relevant thing is the toxicity and the damage that species-inappropriate foods do to the body, and that damage accumulates."

He presents his views with strong conviction and uses loaded language ("toxic garbage," "lying WHO," "brainwashed").
Conclusion:
Joachim Bartoll's article uses a review of a study on UK food rationing to support his long-standing主張 that restricting carbohydrates and seed oils, especially in early life, is essential for preventing chronic diseases. He argues vehemently for an animal-based diet, viewing carbohydrates and plant-based unsaturated fats as fundamentally harmful to human health. While the study provides interesting observational data, the author's interpretation is presented through a lens of strong pre-existing beliefs and should be considered within the context of his stated biases and alternative views on human physiology and nutrition.

The primary food groups severely restricted were sugar, fruits, cereals, rice, chocolate, biscuits, and seed/vegetable oils (including margarine). The author considers these restrictions significant because they involved the reduction of what he deems "extremely toxic and damaging foods rich in carbohydrates and plant-based fats/oils."
The "natural experiment" compared disease rates in over 60,000 participants conceived during (1942-1953) and after the UK food rationing, observing the effect of this period of restricted food availability. Individuals born during sugar rationing had a significantly lower risk of type 2 diabetes, hypertension, and obesity in their 50s and 60s compared to those born after rationing ended.
After rationing ended, children's sugar intake increased by 50-60% (approximately 25 grams more) and fat intake increased by 10-20% (approximately 6 grams more), totaling about 160 more calories per day. The author interprets this as evidence of the population being "brainwashed" towards unhealthy eating habits, a trend he believes has worsened.
The author believes humans, being obligate hyper carnivores, should consume zero carbohydrates, especially children. His reasoning is that humans manufacture their own glucose through gluconeogenesis as needed, and any carbohydrate intake will elevate blood glucose to damaging levels, harming soft tissues and organs.
The author explains that chronically elevated blood glucose levels from carbohydrate consumption damage cells, including those involved in glucose utilization and storage. When combined with the consumption of plant-based unsaturated fats, which are incompatible with human physiology and prone to oxidation, this damage to cells leads to insulin resistance and eventually type 2 diabetes.
The author argues that "overnutrition" is a misnomer when referring to species-appropriate (animal-based) foods, as the body will simply store or discard excess nutrients without harm. The problem with excessive carbohydrates and seed oils is not "overnutrition" but "overfeeding on toxic species-inappropriate foods" that cause significant damage over time.
The author differentiates between natural, healthy animal fats (including saturated fats, cholesterol, and omega-3s) and toxic, damaging plant-based unsaturated oils (polyunsaturated and monounsaturated). He considers plant-based unsaturated fats harmful because they are not chemically compatible with human physiology, are prone to oxidation and rancidity, and their metabolism produces toxic byproducts.
Elevated blood glucose levels increase the oxidation of plant-based unsaturated fatty acids. Since these fatty acids are already difficult for the body to process, increased oxidation further hinders their conversion or breakdown, causing them to circulate longer in the bloodstream, leading to more tissue damage before detoxification.
The author strongly disagrees with Examine.com's suggestion of "limited understanding of the underlying mechanism," asserting that the detrimental effects of carbohydrates and seed oils are based on "very simple biology, physiology and biochemistry." He believes the link between early-life sugar exposure and later chronic disease risk is well-established.
The author recommends a diet completely devoid of plant-based and processed foods for the entirety of life, especially for children. He believes humans are naturally meant to consume an animal-based diet, and any exposure to carbohydrates and seed oils causes unnecessary damage.
Gluconeogenesis: The metabolic process by which organisms produce glucose from non-carbohydrate precursors, such as amino acids and glycerol. The author argues this is how humans are meant to obtain glucose.
Obligate Hyper Carnivore: An animal that requires a diet consisting primarily of animal flesh to thrive. The author asserts that humans fall into this category.
Seed/Vegetable Oils: Oils extracted from plant seeds or fruits, often high in polyunsaturated and monounsaturated fats. The author considers these to be toxic and damaging.
Unsaturated Fats: Fatty acids that contain one or more double bonds in their carbon chain, commonly found in plant-based oils. The author views these as incompatible with human physiology.
Oxidation/Rancidity: The process by which fats and oils react with oxygen, leading to the formation of harmful compounds and a characteristic unpleasant taste and smell. The author claims plant-based unsaturated fats are prone to this in the body.
Bioavailable: The degree and rate at which a substance (e.g., a nutrient) is absorbed into a living system or is made available at the site of physiological activity. The author argues that nutrients in animal-based foods are more bioavailable to humans.
Species-Appropriate Diet: A diet that is natural and optimal for a particular species, based on its evolutionary history and physiological needs. The author believes this for humans is a solely animal-based diet.
Toxic Load: The accumulation of harmful substances or toxins in the body. The author believes that carbohydrates and seed oils contribute significantly to the body's toxic load.
Atherosclerosis: A disease in which plaque builds up inside the arteries, potentially leading to heart attack and stroke. The author links this to the consumption of unsaturated fats and high blood glucose.
Glycosylation: The non-enzymatic reaction of glucose molecules with proteins or lipids, leading to the formation of Advanced Glycosylation End-products (AGEs), which can contribute to tissue damage and disease. The author mentions this in the context of high blood glucose levels.
- Frequently Asked Questions on Carbohydrate and Seed Oil Restriction in Early Life
1. What is the main argument presented in the text regarding early life diet and chronic disease?
The central argument is that restricting carbohydrates (sugars) and unsaturated fats from seed/vegetable oils in early life (from conception to around two years of age) can significantly prevent the development of chronic diseases like type 2 diabetes, hypertension, and obesity later in life. This is based on the idea that these foods are toxic and damaging to the developing body.
2. What evidence from a "natural experiment" is discussed to support this argument?
The text discusses a study that observed disease rates in individuals conceived during and after the period of food rationing in the United Kingdom (1942-1953). During this time, sugar and seed/vegetable oils, along with other carbohydrate-rich foods, were strictly rationed. The study found that those born during the rationing period, who had lower exposure to these substances in early life, had a significantly lower risk of type 2 diabetes, hypertension, and obesity in their 50s and 60s compared to those born after rationing ended.
3. Why does the author consider sugar and seed oils to be particularly harmful, especially for children?
The author views sugar (as representative of all carbohydrates that convert to glucose) as damaging because it raises blood glucose levels above the natural levels maintained by the body's own glucose production (gluconeogenesis). These elevated levels are believed to damage soft tissues and organs. Seed/vegetable oils, being plant-based unsaturated fats, are considered incompatible with human physiology, prone to oxidation and rancidity, and contribute to inflammation and other health issues, especially when combined with high blood glucose. Children are considered particularly vulnerable due to their rapid development.
4. What is the author's perspective on the human dietary needs for carbohydrates and fats?
The author argues that humans are obligate hypercarnivores who do not require any carbohydrates, as the body can produce necessary glucose through gluconeogenesis using animal fats and proteins. In contrast, animal fats (including saturated fats, cholesterol, and omega-3 polyunsaturated fats) are considered essential and non-toxic. Plant-based unsaturated fats (seed/vegetable oils) are deemed unnecessary and harmful.
5. What does the author say about "overnutrition" and the consumption of a species-appropriate diet?
The author dismisses the concept of "overnutrition" when it comes to a species-appropriate diet consisting solely of animal-based foods. They contend that the body will utilize what it needs from such nutrient-dense, bioavailable foods and simply discard the rest without causing harm. "Overfeeding" on toxic, species-inappropriate foods (like carbohydrates and seed oils) is what leads to damage, not an excess of actual nutrients from animal sources.
6. How does the author explain the link between consuming carbohydrates and seed oils and the development of chronic diseases like type 2 diabetes and cardiovascular issues?
The author explains that consuming carbohydrates leads to chronically elevated blood glucose, which damages tissues and can lead to insulin resistance and type 2 diabetes. The consumption of plant-based unsaturated fats (seed oils) contributes to this damage through oxidation, rancidity, and their incompatibility with human physiology. The combination of high blood glucose and these oxidized fats is seen as a major driver of atherosclerotic plaques and cardiovascular complications.
7. What is the author's critique of the "calorie" concept in relation to diet and health?
The author argues that "calories," being a measure of heat, are irrelevant to human physiology. They believe that the focus should be on the toxicity and damaging effects of species-inappropriate foods rather than on their caloric content. The body's response to food is based on its biochemical and physiological compatibility and nutrient density, not just its heat value.
8. What dietary recommendations does the author strongly advocate, particularly for early life and beyond?
The author strongly recommends a diet completely devoid of plant-based and processed foods for all stages of life, especially during pregnancy, infancy, and childhood. They advocate for a natural, species-appropriate diet based primarily on animal-based foods, including mother's milk for infants, followed by animal products. They believe that any exposure to carbohydrates and seed oils will cause damage and is entirely unnecessary.

Bartoll cites an estimated mean daily intake of 86 grams of "simple sugars" among preschool-aged children today, according to the WHO10 ....
However, the author believes that counting only "simple sugars" is misleading, as "all carbohydrates turn into glucose that damages the body"10 .... He states that humans are "obligate hyper carnivores" who manufacture their own glucose as needed through gluconeogenesis and are meant to run on animal fats13 .... Therefore, according to Bartoll, humans should not consume any carbohydrates at all, especially children, who should consume "ZERO, as in 0 grams carbohydrates a day"13 .... He cites statistics indicating that children aged 2 to 5 years consume an average of 220 grams of carbohydrates per day, which he deems "extreme" and a "total disaster"14 ....
When analyzing populations decades later, the study showed that participants born during sugar rationing had a 36% lower risk of type 2 diabetes, a 19% lower risk of hypertension, and a 31% lower risk of obesity compared to those born after rationing ended20 .... These protective effects increased with the duration of time individuals spent growing up during food rationing21 .... Bartoll finds this unsurprising, as he believes that consuming carbohydrates leads to unnaturally elevated blood glucose levels, damaging soft tissues, muscles, organs, arteries, and the cardiovascular system21 .... He argues that this damage is intensified by the presence of seed/vegetable oils (plant-based unsaturated fats), which he considers chemically incompatible with human physiology and prone to oxidation and rancidity22 ....
Bartoll summarizes that elevated blood glucose levels above normal physiological ranges maintained by gluconeogenesis can lead to insulin resistance, beta cell dysfunction, glucagon overproduction, tissue damage, and potentially diabetes27 .... He posits that obesity is not a direct cause of diabetes or organ damage but rather a consequence of prolonged exposure to chronically high blood glucose levels and a toxic load28 ....
The author dismisses the concept of "overnutrition" in the context of a species-appropriate (animal-based) diet, stating that the body will use what it needs and discard the rest31 .... However, he argues that consuming toxic carbohydrates and seed oils is "overfeeding on toxic species-inappropriate foods," which causes significant damage37 .... He also contends that foods high in carbohydrates and/or seed oils lack bioavailable nutrients, leading to nutrient deficiencies, hunger, cravings, overeating, and obesity40 ....

The author states that polyunsaturated and monounsaturated fatty acids from plants are not considered beneficial or necessary for maintaining human health, based on biological and physiological principles10 .... They assert that unsaturated fatty acids characteristic of plant-based foods are not a part of human physiology14 .... When humans consume these plant-sourced unsaturated fats, their bodies must undertake a conversion process involving desaturation, elongation, and isomerization15 .... This conversion, however, can lead to the formation of toxic residues like epoxides and hydroperoxides, as well as oxidation into reactive aldehydes and ketones, potentially causing inflammation and oxidative stress15 ....
The author emphasizes that any kind of plant-based unsaturated fat will cause damage in the body, and this damage is amplified if blood glucose levels are also high, as it increases the oxidation of these fatty acids12 .... Since these fatty acids are not chemically compatible with human physiology, the body struggles to process them, and the more oxidized they are, the longer they circulate in the bloodstream, causing tissue damage before being detoxified by the liver and kidneys17 ....
The author suggests that only a small portion of consumed seed/vegetable oils will be converted for energy, while the majority will cause extreme tissue damage and eventually be discarded by the body21 .... They strongly advise removing all plant-based and processed foods, including seed oils, for the entirety of one's life, especially for children24 ....
Discuss Early life nutrition.
Early-life nutrition, defined as nutrition during the first 1,000 days of life from conception to 2 years of age, is considered critical for growth and development1 ....

The author argues that this forced restriction of these "toxic and damaging foods"11 ... rich in carbohydrates and plant-based fats/oils actually protected those who were conceived and grew up during that time10 . This period supposedly resulted in a much lower toxic load on developing bodies due to the reduced consumption of carbohydrates and seed oils15 ....
Interestingly, pregnant mothers, children, and invalids received more eggs and meat during the rationing16 .... The author suggests that this meant children during this period had a lower chance of developing nutrient deficiencies while also being less exposed to toxic foods16 .... However, the author downplays the significance of plant-based foods in providing usable nutrients15 ....
The author highlights that the end of food rationing led to an immediate increase in children’s sugar intake (50%-60% increase, approximately 25 grams more) and fat intake (10%-20% increase, approximately 6 grams more), totaling about 160 more calories per day17 .... The author views this post-rationing dietary shift negatively, noting that preschool-aged children today consume an estimated mean daily intake of 86 grams of simple sugars according to the WHO, and an average of 220 grams of total carbohydrates per day in the US24 .... The author, adhering to a "hyper carnivore" view, believes humans, especially children, should consume zero carbohydrates27 ... and that humans are meant to run on animal fats, manufacturing their own glucose through gluconeogenesis27 ....

Discuss Chronic disease prevention.
The sources strongly suggest that restricting carbohydrates and seed oils, especially in early life, is a crucial strategy for preventing chronic diseases later in life1 .... According to Joachim Bartoll, the author, a study reviewed on Examine.com offers further evidence for the "extreme destructive forces of sugar, as in carbohydrates, and unsaturated fats, as in seed/vegetable oils"2 ....
The author discusses the food rationing in the United Kingdom during World War II (1942-1953) as a "natural experiment" where the population experienced a restriction of sugar and subsequently other carbohydrates and seed/vegetable oils3 .... Bartoll argues that this involuntary restriction of what he terms "extremely toxic and damaging foods rich in carbohydrates and plant-based fats/oils"6 ... had a protective effect against chronic diseases for those who grew up during that period9 .
Key findings related to this period include:
•
Sugar was one of the first items to be rationed, starting in January 1940, followed by fruits, cereals, rice, chocolate, biscuits, and seed/vegetable oils, including margarine5 ....
•
The end of food rationing led to a significant increase in children's sugar intake (50%-60% increase, approximately 25 grams more per day) and fat intake (10%-20% increase, approximately 6 grams more per day), totaling about 160 more calories daily11 ....

The author notes that these protective effects increased with the duration of time spent growing up during food rationing15 ....
Bartoll interprets these findings through his belief that carbohydrates lead to unnaturally elevated blood glucose levels, which damage various tissues and organs, including the cardiovascular system15 .... He argues that this damage is amplified by the consumption of plant-based unsaturated fats (seed/vegetable oils), which he considers "not chemically compatible with human physiology" and prone to oxidation and rancidity16 ....
The author asserts that humans are "obligate hyper carnivores" who should consume a diet consisting mainly of animal-based foods and zero carbohydrates, as the body can produce its own glucose through gluconeogenesis22 .... From this perspective, consuming carbohydrates is detrimental, especially for children22 ....
Bartoll also dismisses the significance of "calories" in understanding health and disease, focusing instead on the toxicity of species-inappropriate foods like carbohydrates and seed oils28 .... He believes that these foods are often devoid of bioavailable nutrients, leading to deficiencies, hunger, cravings, and ultimately overeating and obesity33 ....
In terms of chronic disease prevention, Bartoll strongly recommends eliminating all plant-based and processed foods from the diet for the entire lifespan, especially for children, who he believes naturally prefer animal-based foods37 .... He refutes the idea that the underlying mechanisms of harm from these foods are not fully understood, stating it is "very simple biology, physiology and biochemistry"37 ....
In summary, the sources, primarily through the interpretation of Joachim Bartoll, emphasize that restricting carbohydrates and seed oils, particularly during the crucial early years of life, is a fundamental strategy for preventing chronic diseases such as type 2 diabetes, hypertension, and obesity in adulthood. This is attributed to the avoidance of elevated blood glucose levels and the consumption of toxic, non-species-appropriate fats, with a strong recommendation for a diet based primarily on animal-based foods1 ....
Discuss Wartime food rationing.
The sources discuss wartime food rationing in the United Kingdom during World War II, specifically from 1942 to 19531 .... This period is examined as a "natural experiment" where a population was exposed to a specific condition – the rationing of food, particularly sugar1 ....
During this time, the UK implemented strict rationing measures for various imported foods to ensure fair distribution2 . Sugar was one of the first items to be rationed, starting in January 19402 . This was quickly followed by other items including:
•
Fruits, cereals, rice, chocolate, biscuits, and seed/vegetable oils, including margarine4 .... These are characterized by the author as "extremely toxic and damaging foods rich in carbohydrates and plant-based fats/oils"4 ....
•
Dried fruit, rice, peas, tinned tomatoes, sweets, and chocolate were added to the list in 19422 .
•
Other items like margarine, jam, cheese, and eggs were rationed in 19412 .
•
Bacon and ham were rationed from 8 oz to 4 oz per person per week7 ....
•
Cheese was rationed to ensure a steady supply7 ....
•
Sausages and cold cuts were generally part of the broader meat rationing7 ....
•
Various canned goods, including fruits, vegetables, and meats, were rationed using a points system7 ....
Rationing ended gradually, with sugar rationing ceasing in February 19532 ..., and all other food rationing ending in July 19549 (Note: Source2 states July 1953). Tea remained rationed until October 19522 .
The author notes that while some cuts of meat and eggs were slightly restricted, the more severe restrictions involved processed dairy and processed meat products that were usually imported, such as different cheeses, sausages, bacon, cold cuts/deli meats/ham, and canned products5 ....
Importantly, pregnant mothers, children, and invalids received more eggs (double the ration) and also more meat7 .... Pregnant women and children under five were given priority access to milk and eggs, while some invalids were allowed more milk and cheese12 . The author interprets this to mean that children during this period had a lower chance of developing nutrient deficiencies while also being less exposed to toxic foods8 ....
The author argues that this food restriction resulted in a large restriction of "toxic plant-based garbage," especially carbohydrates and seed oils, which contributed to a much lower toxic load on the body10 .... They believe that this occurred without significantly restricting nutrients because they do not consider plant-based foods to have bioavailable nutrients anyway10 ....
The end of food rationing led to a significant increase in children's intake of sugar (50%-60%) and fat (10%-20%)14 .... The author uses this to highlight what they see as the "brainwashed" state of the population regarding diet14 ....
Decades later, the study found that participants born during sugar rationing had a significantly lower risk of type 2 diabetes, hypertension, and obesity compared to those born after rationing ended17 .... The author attributes these protective effects to the lower lifetime exposure to high blood sugar and seed/vegetable oils during their early development20 .
TRANSCRIPT OF PODCAST
Welcome to the daily briefs.info Lenny and Maria deep dive podcast show review of the article Restricting Carbohydrates and seed oils in early life will prevent chronic disease later in life by Joah Kim Bartal.
Wow, that's a mouthful.
Yeah. Well, you know, it's a pretty dense topic, so we've got to lay it all out there, right? Fair enough.
Today, we're diving deep into the arguments in this article. It's a pretty bold idea. Could limiting carbs and seed oils when we're young really be the key to avoiding chronic diseases down the road?
It's a thoughtprovoking concept for sure.
The author uses a really interesting example to illustrate their point. They look at the food rationing in the UK during and after World War II almost like a natural experiment.
That was back in 1942 to 1953. Right.
Right. Smack dab in the middle of the 20th century. Sugar and seed oils, those were heavily restricted back then. The author basically argues that this forced restriction of what they call toxic and damaging foods actually protected those who grew up during that time. They ended up with a lower risk of chronic diseases as adults. Okay, so picture this. It's wartime Britain and as the article points out, one of the first things to be rationed was sugar. Then came a whole wave of other restrictions. Fruits, cereals, rice, even chocolate, and biscuits were limited. And really importantly for a discussion, seed and vegetable oils like margarine. That's a pretty big shift in the typical diet, isn't it?
It was a complete overhaul.
And the author laser focuses on the restricted foods that they believe are the most harmful, the high carb stuff. and plant-based fats. What's interesting is that some animal products like certain meats and eggs also saw minor restrictions. But the big limitations were on imported processed dairy and meats probably due to wartime supply chains.
Right. The article also makes it clear that certain groups like pregnant women, children, and invalids actually got more eggs and meat during this time. It's like it had a little extra nutritional safety net even though the general population was on a stricter diet.
And you know how the author interprets this? They suggest that this rationing period inadvertently created at a time of much lower toxic load on developing bodies because people weren't eating as many carbs and seed oils. They kind of downplay the extra eggs and meat for those vulnerable groups because they don't really see plant-based foods as providing truly usable nutrients anyway.
Now, here's where things get really interesting. The article talks about what happened when the rationing finally ended. Kids started eating way more sugar, like a 50 to 60% increase, which is about 25 more grams per day.
Wow, that's a lot of extra sugar.
And fat intake went up to about 10 to 20% roughly an extra 6 g a day. So that's about 160 more calories daily.
The author isn't exactly thrilled about this post-rationing dietary shift. They point to the fact that preschoolers today eat even more sugar than that.
The WHO estimates it's around 86 gram of simple sugars per day. And the author goes beyond just sugar. They're really worried about total carb intake. Citing data from the US that shows kids aged 2 to 5 eat an average of 220 grams of carbs per day. For the author, this is a huge problem and a major deviation from what they believe is a healthy diet.
So, the author has a very specific view on carbs. It's called hyper carnivore, and the article mentions it briefly. It basically says that humans don't need to eat any carbs at all.
So, no bread, no pasta, none of that.
Exactly. The argument is that our bodies can make all the glucose we need through a process called gluconneogenesis. That's where our bodies make glucose from things like protein and fat instead of carbs. So, from this perspective, eating carbs just makes our blood sugar spike. unhealthy levels.
That's a pretty big departure from what most nutrition experts say.
It is. The author believes that humans are meant to mainly run on animal fats and the glucose our bodies naturally produce. Any extra carbs in the diet are seen as potentially harmful, especially during childhood when our bodies are still developing. And the article really highlights the contrast between this zero carb view and how many carbs young kids are actually eating today. The author suggests it's a big reason why we see so many health issues later in life.
It's definitely a different way of looking at things.
Now, with that understanding of what people were and weren't eating during and after rationing, the article looks at the long-term health outcomes. It's pretty amazing. People who were conceived during the sugar rationing period were actually healthier decades later compared to those born after rationing ended, they had a 36% lower risk of type 2 diabetes, a 19% lower risk of hypertension, and a 31% lower risk of obesity. Those are some seriously impressive numbers.
That's remarkable. And the author connects these positive effects directly to lower lifetime exposure to high blood sugar. They argue that those born during rationing had lower blood sugar because they ate fewer carbs growing up. And they were also exposed to less of what the author considers the harmful effects of seed and vegetable oils. The author believes that consistently high blood sugar can damage our tissues, muscles, organs, and our whole cardiovascular system over time. And they say this damage is even worse when we combine it with plant-based unsaturated fats, which they claim are not chemically compatible with human physi. technology and prone to going rancid.
Let's break that down a bit. The article is very clear that eating carbs leads to what the author considers unnaturally high blood sugar levels. And this in turn is said to directly harm our tissues and can lead to insulin resistance and type 2 diabetes. They actually present obesity not as a root cause of these problems, but as a consequence of constantly high blood sugar and what they call toxic load from eating the wrong foods.
It's a different way of framing the whole issue of metabolic disease. It's not just about how many calories you eat and how much you weigh. It's about the specific impact of blood sugar spikes caused by carbs. The author's view is that our body's own glucose production through gluconneogenesis is enough for us and any extra glucose from carbs is just bad for us in the long run.
Now, let's talk about the author's views on seed and vegetable oils. They're pretty strong opinions. They basically say that these polyunsaturated and monounsaturated fats that come from plants are inherently problematic because they're so easily oxidized and can go rancid even before we eat. them. They believe this instability is a major contributor to health issues.
The author argues that these plant-based unsaturated fats just aren't a natural part of how our bodies work. They say our bodies have to go through all these complicated steps to even try to use them like desaturation, elongation, and isomerization. And according to the article, this conversion process can create harmful byproducts like toxic residues and more oxidized compounds which then lead to inflammation and oxidative stress throughout the body.
And the article doesn't paint a pretty picture when it comes to combining these seed and veget vegetable oils with a high carb diet. They link it to the development of plaque in our arteries and all sorts of cardiovascular problems. The author goes so far as to say that these plant-based fats don't actually do anything good for us and we don't even need them because we can make all the essential fatty acids we need from animal sources.
It all boils down to the author's core belief that humans evolve to thrive on animal fats and don't have any biological need for fats from plants. They think our bodies are perfectly designed to handle animal fats, but plant-based unsaturated ated fats just overload our system with toxins.
The article also touches on the topics of nutrient deficiencies, constant hunger, and this idea of over nutrition. They describe foods high in carbs and seed oils as lacking nutrients that our bodies can easily absorb and use.
So, we're basically eating empty calories.
That's the idea. The author suggests that this lack of essential nutrients makes us feel even hungrier and crave more food because our bodies are trying to get what they need. This leads to overeating and weight gain and Here's an interesting point. The author completely rejects the idea of over nutrition when it comes to nutrient-dense animal-based foods. They believe that if we eat the foods our bodies are meant for, our bodies will use what they need and get rid of the rest without any problems. But when it comes to carbs and seed oils, the author sees it as overfeeding on toxic species, inappropriate foods, no matter how many calories you're eating.
It's a very black and white perspective.
It is. And speaking of black and white, the author also critiques the study they're reviewing and how the original researchers interpreted their findings. While those researchers seem to focus on sugar as the main culprit, this author points out that people also started eating a lot more fat after rationing ended. They emphasize the importance of distinguishing between what they consider healthy animal fats and toxic plant-based oils when we analyze these health outcomes.
It makes you think about how we interpret these studies and what we choose to focus on.
Exactly. The author is also very much against using calories as a measure of how healthy a food is. They argue that are just a way to measure energy and don't reflect the complex things that happen in our bodies when we eat different foods. Instead, they focus entirely on how toxic and potentially harmful these species inappropriate foods are. And they reiterate their belief that only protein and fat are truly essential for humans because our bodies can make their own glucose.
It's a very different approach to nutrition.
Absolutely. Finally, the article addresses the importance of early life nutrition, especially those first 10,000 days of life. While agreeing that this period is crucial, They reframe the concept of overnutrition in this context as simply eating too much of the wrong foods rather than just eating too much in general. The advice given is pretty straightforward. Eliminate all plant-based and processed foods from the diet for life. And this is especially important for kids as they're growing. And the author dismisses the idea that we don't fully understand the dangers of these foods. They say it's all just simple biology, physiology, and biochemistry.
The author's confidence in these principles is striking. It's a very different perspective. from what you often hear in mainstream nutrition, which can be more nuanced and sometimes even contradictory. They present a very specific and unwavering view on what makes up a healthy human diet, especially in those early years, and the impact it can have on preventing chronic diseases later in life.
So, to sum up this deep dive, we've explored the arguments laid out in the daily brief notinfo review of the article, restricting carbohydrates and seed oils in early life will prevent chronic disease later in life by Joe Kimbart. We've looked at the author strong claims about how damaging both carbs and seed oils can be, particularly during those crucial early years of development and their potential long-term effects on our health.
This deep dive gives us a lot to think about when it comes to the long-term consequences of our dietary choices, especially those we make early in life. It challenges some common beliefs about nutrition and offers a unique interpretation of historical changes in diet and their effects on health.
It definitely provides a different lens through which to view the connection between what eat in our early years and our risk of developing chronic diseases as we age. All based on this specific take on a significant historical period.
It really makes you wonder about what the ideal human diet actually is and the lasting impact of those early nutritional choices on our long-term well-being.
