In the early 1900s, many people began moving into cities, increasing the overall illness rates with an increased population density and unhealthy living conditions. Also occurring around this time, widespread medicines became more commonly distributed. Advertising picked up, targeting the women of the households in an attempt to sell more product to entire households. “Dr Caldwell’s guide to Heath Home Cookbook” is a great example of this, as the pepsin syrup company combined recipes and advertisement to create a book that would be bought. This shows the slow shift from the “food exclusively can heal” to a “food can play a part in supporting healing” mentality. This development brought us deeper into the modern century, setting the stage for interactions between food and medical knowledge.
