Sunbathing, or at least the right supplement vitamin Dcan make itself felt in terms of type 2 diabetes. That is, in lowering the risk. Applies to 400 million adults worldwide. According to a new meta-analysis signed by Tufts Medical Center, taking regular doses of vitamin D can lead to a 15% lowering in the possibility of developing full-blown diabetes among adults with prediabetes. What is it about? A condition characterized by hyperglycemia not diagnostic of diabetes and a high risk of developing type 2 diabetes and cardiovascular disease.
A person with prediabetes does indeed blood sugar levels higher than normal but not high enough to lead to a diagnosis of type 2 diabetes. However, they are even more at risk of developing the condition in the future. The researchers reviewed and analyzed three clinical trials during their study. Discovering, in a three-year follow-up period, a limited but interesting effect: new-onset diabetes occurred in 22.7% of adults who received vitamin D compared to 25% among those who received a placebo product.
Based on these findings scientists – as reported in the specialized journal Annals of Internal Medicine – then sought to estimate how vitamin D supplements impacted adults with prediabetes worldwide. Discovering precisely that low-cost vitamin D supplements that many take, especially during the winter season, could delay the development of diabetes. Even if the benefit is limited, in macroscopic terms it could become very significant.
“Our results show that vitamin D provides a modest benefit in reducing the risk of diabetes in adults with high-risk prediabetes,” he explained. Anastassios Pittashead of endocrinology, diabetes and metabolism at Tufts Medical Center, according to a statement released to swns – that could have significant implications for public health for the 96 million adults in the United States (38% of all US adults) and more than 400 million people worldwide who are at risk of diabetes. However, there are still some important unknowns.” Which ones are they? For example we do not know the optimal dose or formulation of vitamin D useful to achieve these results and we don’t know if we should aim to achieve one specific level of vitamin D in the blood in order to maximize benefits in this population, with little or no risk of side effects. We will work on it with other investigations already in the pipeline.
In general, however, what matters at the moment is that “in studies designed specifically to test the hypothesis that vitamin D reduced the rate of progression to diabetes in people with prediabetes, the risk of developing the disease was ultimately consistently lower in the vitamin D group compared to the placebo group.
Type 2 diabetes usually affects the elderly more than other demographic groups but in recent years it has become also more common among young people for the most varied causes, obviously starting from poor nutrition. Some symptoms include increased hunger, unintentional weight loss, tiredness, blurred vision, and increased thirst. On the other hand, vitamin D is a fat-soluble vitamin abundant in foods such as oily fish, red meat and egg yolks. But the body also produces it when the ultraviolet rays of sunlight they affect the skin, making supplements especially useful during the winter months. Vitamin D is vital for maintaining healthy bones, teeth and muscles, as well as helping regulate calcium in the body.
