Are Lectins Linked to Allergens?
There is speculation among certain sources that lectins may contribute to the development of conditions such as irritable bowel syndrome (IBS). Interestingly, the top eight food allergens, including dairy, eggs, wheat, soy, peanuts, tree nuts, fish, and shellfish, are also known to contain high levels of lectins. For some individuals, lectins can trigger adverse reactions in their blood cells, leading to allergic responses and various health problems. Advocates of a lectin-free diet argue that humans were not evolutionarily adapted to consume foods with high concentrations of lectins.
The Impact of Lectins on Grain Consumption
The consumption of grains has significantly changed from the diet of our ancestors. In the past, grains were only consumed when they were in season, but today, grains are readily available throughout the year. This constant exposure to grains has raised concerns among experts who believe that the human body is not designed to handle the excessive consumption of grains that is prevalent in modern diets.
In recognition of this concern, the USDA food guide has revised its recommendations regarding grain consumption. While the previous guideline suggested consuming six to 11 servings of grains per day, the updated recommendation advises adults to consume three to eight servings, depending on their age and sex.
