Medical Acceptance of the Celiac Pandemic: Is the Decades-Old Ridicule Ending?
Those carrying the gene for celiac disease, about a third of the population, can easily bring out the condition. Just eat enough wheat and you can trigger the celiac gene to express itself, resulting in the illness. This is just what’s been happening. Since 1950, the incidence of celiac disease has increased by almost 500%. It’s not just more recognition and diagnosis of the condition but a worsening of the pandemic. While the experts are still calling this explosion a “mystery,” it seems to be yet another example of environmental pressure – namely diet stress – on existing genes. In particular, it’s people stuffing down bagels, bread, pasta, cereal, muffins and many other foods containing gluten. It’s giving babies and young children wheat as their first and primary foods instead of vegetables, fruits and meats, and using wheat as a reward.
