Relying on bread instead of fresh, whole foods comes with serious health risks. Wheat, a staple in many diets, has three major inherent dangers that can seriously impact your health. I call these the downsides of wheat.
1. Gluten: The Inflammation Trigger
Wheat contains gluten, a protein that causes systemic inflammation, affecting multiple organs—including the brain, heart, joints, eyes, and digestive tract. Chronic inflammation not only precedes degenerative diseases like diabetes, cancer, stroke, glaucoma, arthritis, and Parkinson’s disease but also accelerates their progression.
A review in the New England Journal of Medicine linked gluten to over 55 diseases, including osteoporosis, anemia, cancer, canker sores, fatigue, rheumatoid arthritis, and multiple sclerosis. It also affects mental and neurological health, contributing to depression, schizophrenia, dementia, nerve damage, epilepsy, and autism. The paper concluded that 120+ diseases are associated with gluten consumption. Dr. Joseph A. Murray, MD, notes that gluten often impacts the brain more than people realize.
2. Peptides and Mental Health Risks
Research by Dr. J. Robert Cade, MD, at the University of Florida found that people with autism and schizophrenia often have high levels of peptides in their urine. These peptides come from casein (milk proteins) and gliadin/gluten in wheat, barley, oats, and rye.
Additionally, a study of 30,000 patients from 1969–2008, published in the Journal of the American Medical Association, found that those with gluten sensitivity faced higher risks of death from cancer and heart disease.
Even more concerning, most wheat consumed today—especially in the U.S.—is a hybrid strain with significantly higher gluten content than traditional European wheat.
3. High Glycemic Index: Blood Sugar Spike and Weight Gain
Wheat has a high Glycemic Index (GI) of 71, compared to yams (49) and sweet potatoes (54). High-GI foods spike blood sugar, promoting weight gain and making conditions like diabetes harder to manage.
According to Dr. Mark Hyman, MD, wheat is a major contributor to obesity, diabetes, cancer, dementia, depression, and other modern health issues.
Bottom Line:
Bread and wheat-based foods are not just empty calories—they can trigger inflammation, disrupt mental and physical health, and contribute to chronic disease. Choosing whole, natural foods instead of processed wheat can make a profound difference in your long-term health.
