With fatigue, the root of the problem can range widely from anemia and hypothyroidism to depression and hypoglycemia. It goes without saying that proper nutrition is a fundamental key to wellness. And this can certainly cause fatigue. If it is found that blood sugar irregularities are causing the fatigue then a comprehensive strategy needs to be taken to balance blood sugars including dietary modifications. And while this topic deserves a lengthy discussion on everything from lifestyle changes and the use of important botanical medicines, the quickest and easiest way to clean up your diet is to cut back on sweet and processed foods and get back to the legumes, grains, fruits, and veggies.
Whole foods are still the best foods.
Recall also that there are certain nutrients that are crucial for blood sugar metabolism. One of them is chromium. Check to see that your multivitamin includes it. As for food allergies, the first step is to identify the food allergens themselves and eliminate them from the diet. This can be difficult, especially if you find out that you are allergic to something you enjoy.
