If you eat a healthy balanced diet, you should be getting your basic nutritional requirements fulfilled. You don't need oodles of Vit. C every day. But govt daily recommendations vary depending on region to region. http://www.ajfand.net/Issue-VIII-files/pdfs/AJFAND%20Vol%205%20No%201%20Peer%20Reviewed%20Article%20No%206.pdf Many foods like strawberries, oranges, and even potatoes (esp sweet) have vitamin C in them. Foods tend to lose nutritional effect during processing though. Try to make your own foods and steam or eat raw veggies and fruits when possible to decrease losses. Avoid commercially processed, esp. canned foods and try to make your own. Many commercial products are too high in salt and preservatives. Use whole grains, reducing white grains as much as possible, perhaps only as an occasional empty calorie "treat." I say empty calorie, because that's what processed flours are. High calories with low nutritional benefits. Use variety in your diet. Traditional one-types of foods have been associated with metabolic conditions, such as traditional beans and rice found to be associated metabolic syndrome amongst Puerto Rican older adults. http://www.ars.usda.gov/research/publications/publications.htm?SEQ_NO_115=239065 The following is a study (on mice) showing supplemental Vit c did was not shown to be effective protection against gastric Cancer, although Low Vit C in humans is associated with gastric cancer and more severe H-pylori gastritis. http://www.ars.usda.gov/research/publications/publications.htm?seq_no_115=217763 High vitamin C intake is associated with lower bone loss in elderly men. http://www.ars.usda.gov/research/publications/publications.htm?seq_no_115=227719 USDA research suggests taking Vit C supp (and E) are safe. http://www.ars.usda.gov/research/publications/Publications.htm?seq_no_115=181421 BUT--because I'm trying to be objective and fair, JAMA did a study on potential mortality rates related to antioxidant intakes. In Conclusion they stated: "We did not find convincing evidence that antioxidant supplements have beneficial effects on mortality. Even more, beta carotene, vitamin A, and vitamin E seem to increase the risk of death. Further randomized trials are needed to establish the effects of vitamin C and selenium." http://jama.ama-assn.org/cgi/content/full/297/8/842 These are mainly 2005-2007, keep in mind. Now, according to Oprah, you can "shake, shake shake" a liquid diet and lose pounds of fat. Then she bloats up like a dead dog on the side of the road. So she goes on another fad diet. Then bloats back up. And another, and another...bloat, bloat. FADS DON'T WORK! I have worked with doctors that prescribe Vit C drips on their patients while in the ICU. It creates havoc when you have a patient that only has one good vein and most meds can not be mixed with the drip. If you do feel as if you're not getting enough from your foods and are worried about whether you should take supplements, don't use Oprah or any other Hollywood spangled person as your guide. Call your doctor. Don't allow yourself to stress out about something you're unsure about. Too much stress is bad for your health too. Too much of anything can be toxic, but inefficient amounts are unhealthy too.
