Hi! I'm Stelios Pantazis. I'm a doctor and I specialize in medical nutrition and metabolic disorders. Today, I'll tell you about the importance of vitamin D in the treatment of diabetes. In the video, I'm using the term "diabetes", but I'm exclusively referring to type 2 diabetes. I'd like to present a study that has been recently published and tried to associate the intake of vitamin D with insulin resistance in people that have been recently diagnosed or run a great risk of diabetes. The observation lasted six months, and the 96 participants in the study received 5,000 IU of vitamin D per day, which is an amount higher than the one considered safe, which is 4,000 IU per day. Obviously, I'd like to stress that if you decide to take so much vitamin D, you should definitely be observed by a doctor. It has been scientifically proven that both people suffering from diabetes and people not suffering from it are very often vitamin-D deficient all over the world. However, this study has shown that if someone starts taking a high dose of vitamin D when they run a high risk of diabetes or they have been recently diagnosed with it, the development of their condition is much better. This may be attributed to the fact that the cells producing insulin, which are in the pancreas, have vitamin-D receptors, which means that they change the insulin production depending on the vitamin-D levels in the body. It seems that vitamin D enters the cells producing insulin and makes them compose and release more insulin to the body. Moreover, it is believed that vitamin D helps these cells survive longer mainly through the effect of vitamin D on the immune system. More recent studies have also shown that cells on which insulin has an effect also have vitamin-D receptors, and it seems that increased vitamin D helps insulin have a stronger effect on these cells and stimulate them to absorb the sugar contained in the blood. As a result, blood sugar decreases. All these may explain why vitamin D can help in the treatment of diabetes, but I should point out some important facts about this study. First of all, the results are significant, but not impressive. Namely, the help of vitamin D in these cases is useful, but in no case is it remarkable. I'd say that the results were existent, but moderate. Moreover, the dose of vitamin D used was too high. In the long run, namely over the years, this may not be safe for everyone. I believe that most people that will take such a high dose for ten consecutive years will possibly have no health problems. On the other hand, I'm sure that a very low percentage of people would have some problems. As I've repeatedly said on this channel, diabetes is mainly a diet problem and it mainly comes from a long-term unhealthy diet. Both drugs and dietary supplements that someone may take can help a little or, in the best case scenario, moderately, but the most significant results will only come from a healthy diet and weight loss, if someone is overweight, as many people suffering from diabetes are. Particularly belly fat, which has the worst effect on the risk of diabetes and brings about most quickly the negative effects of diabetes. Don't expect any magic pills and dietary supplements to treat or prevent diabetes. Start a healthy diet as soon as possible. This is the most important thing.
