Although as a general rule, dietary supplement labeling and marketing are not allowed to make disease prevention or treatment claims, the U.S. FDA has for some foods and dietary supplements reviewed the science, concluded that there is significant scientific agreement, and published specifically worded allowed health claims. An initial ruling allowing a health claim for calcium dietary supplements and osteoporosis was later amended to include calcium supplements with or without vitamin D, effective January 1, 2010. Examples of allowed wording are shown below. In order to qualify for the calcium health claim, a dietary supplement much contain at least 20% of the Reference Dietary Intake, which for calcium means at least 260 mg/serving.

Actually, more people suffer from food intolerances, which don't involve the immune system. However, food intolerance symptoms—such as intestinal distress—may mimic those of a food allergy. If you have a food intolerance, talk to a nutritionist about diagnosis and treatment; if you have food allergies, you need to see an allergist. Whether you have food allergies or intolerance, you will need to develop a diet that fits your needs and avoids foods that trigger a reaction.
Brigitte Zeitlin, M.P.H., R.D., C.D.N., founder of the New York-based BZ Nutrition, tells SELF, "Eating regularly throughout the day keeps your metabolism running at full speed, prevents dips in your energy, keeps you alert and focused, and [can help keep] your weight steady by preventing overeating at later meals." She and other experts recommend eating every three to four hours. If you don't, there are a number of unpleasant symptoms you may encounter.
Watch your portion sizes: Check to see what the recommended portion sizes of foods you eat looks like in the bowls, plates, and glasses you use at home. When dining out avoid "supersizing" your meal or buying "combo" meal deals that often include large-size menu items. Choose small-size items instead or ask for a take home bag and wrap up half of your meal to take home before you even start to eat.
5. Wrap unhealthy foods in tin foil. Wrap healthy foods in plastic wrap. The old saying, “out of sight, out of mind” turns out to have some truth to it. Eating isn’t just a physical event, but also an emotional one. Your mind often determines what it wants to eat based on what your eyes see. Thus, if you hide unhealthy foods by wrapping them up or tucking them away in less prominent places, then you are less likely to eat them.
