Glucose and the Brain

Glucose is the major source of energy for the brain, nervous system, muscles, and many other body’s processes. (Note: the body can get glucose from carbs, proteins, and fats—brain neurons appear to prefer and use almost exclusively glucose from carbs—so eating healthier carbs is essential). Too much glucose can be extremely problematic for individuals with diabetes. When glucose levels are low, decision-making, critical thinking, willpower, and self-control can be impaired. Go easy on simple carbs (especially white sugar, flour, rice, and processed foods made from them) in favor of healthier complex carbs, the preferred source. They can help you maintain your weight in an optimum range as you need smaller amounts to feel satisfied and feel full longer, as compared to foods containing simple sugars and high-fructose corn syrup). Foods that are healthier sources of glucose include whole ancient grains, legumes, and some vegetables. Examples of high-starch veggies include corn, zucchini, and squash. Low-starch veggies include tomatoes and onions, asparagus and celery, mushrooms, cauliflower, green beans, cabbage, cucumbers, and red and green peppers, etc.
