When major lectin-containing foods were introduced to our diet about 10,000 years ago in the form of grains and beans, our health dramatically changed for the worse.

In this quote, Steven Gundry suggests that the introduction of lectin-containing foods, specifically grains and beans, had a negative impact on human health. He traces this change back to about 10,000 years ago, when these foods became a staple part of the human diet. Gundry implies that this shift marked a significant turning point, where our health began to decline as a result of consuming these foods that contain lectins, a type of protein that he argues can be harmful to our bodies.

Gundry’s perspective is rooted in his belief that lectins, which are present in many plant-based foods, can cause inflammation, digestive issues, and other health problems. He suggests that before the widespread consumption of grains and beans, humans likely had a diet that was better suited to their biology, leading to better health outcomes. This view is often associated with his promotion of a lectin-free diet, which he believes can prevent or reverse certain chronic conditions.

The statement reflects Gundry's broader stance on modern diets and how the foods that became common in agriculture may not align with the way our bodies evolved. His critique of grains and beans aligns with a growing movement that questions the health impacts of modern processed foods and advocates for more natural or evolutionary-based eating habits.

Ultimately, this quote highlights Gundry's belief that the advent of agriculture and the shift to a diet rich in grains and beans contributed to a decline in human health, suggesting that many of the chronic health issues faced today can be traced back to these dietary changes. His viewpoint challenges conventional dietary recommendations and advocates for a return to eating habits that he believes are more in line with our evolutionary biology.
