How to practice Carbohydrates
Emphasize complex carbs such as oats, beans, quinoa, fruits, and vegetables. Limit refined grains and added sugars. Combine carbs with protein or fat to blunt glucose spikes. Avoid ultra-low-carb diets unless medically indicated; the brain functions best with steady glucose supply.
The evidence behind Carbohydrates
Large epidemiologic studies link high-quality carbs (whole grains, fruits, legumes) to better cognition and longevity, while high-glycemic diets accelerate decline. Controlled feeding trials confirm improved mood and focus from balanced, low-glycemic meals.
