Processed food and supplementation can be either health promoting or detrimental to health, depending on the food itself. The fact that something is processed doesn't make it immediately bad for us. When isolating main ultra processed foods, most seem to have either no effect or health promoting effect. The ultra processed foods that are most detrimental to health: sugar and artificial-sugar beverages, animal-based ultra-processed foods and sauces and spreads. Reducing those foods in your diet might reduce risk of some diseases. And substitution of "natural" meats with vegan ultra-processed alternatives reduces the risk of cardiovascular disease.
