Would it be an exaggeration to say that sugar and gluten are poisoning most Americans? I would argue that both of these substances, albeit natural, are toxic in levels that are regularly consumed in the United States. As a Registered Dietitian, I have strong views about the subject of nutrition and what merits a “healthy” diet. I am an indomitable supporter of the primal/paleo lifestyle because it makes evolutionary sense. For 95% of human existence the amount of grains, gluten, sugar, and general carbohydrates in the diet was negligible. Today the typical diet of westernized countries includes all those aforementioned categories as staples. Am I extreme in my thinking, a rogue dietitian hell bent on smacking cupcakes out of children’s hands? For a long time I thought so, but I think the medical community is slowly coming around.
One of those coming around in the medical community is David Perlmutter MD, a highly-acclaimed neurologist, who wrote the book Grain Brain: The Surprising Truth About Wheat, Carbs, and Sugar – Your Brain’s Silent Killers. Going into this book I thought I knew the gamut of negative effects that wheat, carbs, and sugar had on the body; however, I had no idea how drastically these compounds affected the brain. Gluten is a protein found in wheat and causes either obvious or subtle inflammation throughout the body. Obvious cases include explosive diarrhea in those with Celiac Disease, subtle cases include bumpy skin or annoying headaches in those with sensitivities. Gluten can affect the brain and body by causing inflammation in the intestines which elicits an immune response and subsequent systemic inflammation. Also, gluten can enter the bloodstream partially digested and act as an exorphin in the brain (think addiction) or deposit in joints, skin, or countless other organ systems. In addition to gluten, excess carbohydrates can cause high blood sugar which results in protein glycation in the blood vessels throughout the body-including the brain. Glycation is a very bad thing because it inhibits neurotransmitter function, and decreases overall cognitive function. A gluten free diet has been shown to be more effective then prescription medications in those suffering with ADHD, Schizophrenia, dementia, Alzheimer’s (delaying the onset), and depression. That last sentence alone is enough to say, “crap Jon why am I eating this piece of bread!”
Another point that I need to harp about is that saturated fat is not bad for you! Saturated fat does not cause high cholesterol or heart disease….period. Watch the informative video I posted for a little history on how we came upon this scientific lie. The cause of heart disease is extremely complex and is mainly from inflammation and oxidized proteins circulating in the blood. This oxidation is caused by a myriad of things including gluten, Omega-6 fatty acids, and trans fat. High cholesterol compared to low total cholesterol is actually found to decrease mortality, increase cognitive function, and decrease risk of depression. If all of these points make you want to curl up into a vegan ball of fear then you should pick up Grain Brain, Wheat Belly, The Primal Blueprint, or Paleo Manifesto. So my prescription to my readers is simple: Try your best to avoid grains, processed oils, eat less than 100 grams of carbs a day, lift weights regularly, walk in nature regularly, sprint once a week, and get plenty of sleep. So get rid of the gluten and excess carbs so you can start feeling like the best version of yourself.
