Why So Many People Have Food Allergies

Fad diets are definitely on the rise, but so are the numbers of people who actually follow the "fad" to survive.

Evidence shows that prevalence of both food allergies and intolerances is growing worldwide.

Recent studies show that food intolerances are almost five times more prevalent today than in the 1950s. As many as 1 in 6 Americans is estimated to have a food intolerance.

But why?

The simplest answer is the lack of variety in our diets. Many of us are eating just a few foods, in different forms, again and again throughout each day. Many of the prepared or processed foods we eat are based on wheat, corn, and soy processed to look different at each meal. And many of the farm-raised animal products in the grocery store were grown using those same few base ingredients.

Since many food intolerance symptoms don’t appear until a certain threshold “dose” is reached, eating a lot of any one food can raise your chances of experiencing symptoms.

Another answer: they don’t make ‘em like they used to. Our food sources have evolved rapidly and significantly to be vastly different from those of our grandparents, not to mention their grandparents. Looking back to past generations, these time frames are but a blink in terms of Homo sapiens’ evolutionary history, but if we were to compare diet over the last 50 years there would be some stark differences:

  • Engineered breeding and corporate farming have become the norm, influencing what ends up on our plate.
  • Our diet is confined to a more limited number of foods—and hugely reliant on wheat, corn, fructose, and soy, all of which can cause inflammation and may contribute to development of intolerances.
  • We have shifted from more traditional methods of preparation to faster, more cost-effective methods that may not be as healthy. For example, the slow and unhurried process through which sourdough bread has traditionally been made is now compressed using new yeasts and artificial rising agents. Unlike modern methods, the slower, natural process of fermentation reduces the gluten content of sourdough breads.

For athletes who subject their bodies to tough workouts each day, it’s even easier to trigger a food intolerance in today’s food environment.
