Many nutritionists recommend that some whole fruit every day can be very beneficial, especially berries. The absorption of fructose in whole fruits is less rapid because of the presence of fiber and other phytonutrients in fruit. Although glucose is found in simple carbs and especially in white sugar, flour, rice, and processed foods made from them), such highly-processed foods are not a preferred source of healthier carbs. Fortunately, glucose is also found in complex healthier carbs. These include legumes, some vegetables, whole seeds and ancient grains. 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. Complex healthier carbs have been found not to spike blood glucose levels in the brain in the way simple carbs tend to do.
