While there’s some degree of controversy swirling around the question of whether vitamin D directly protects you from osteoporosis, it’s clear that this vitamin does improve bone density. As you get older, your bone density naturally decreases, and you become more prone to fractures and other bone-related problems. Consuming your daily dose of vitamin D may reduce your risk of having bone issues when you’re older.
In one study, children who consumed 1,200 IU of vitamin D per day during the winter were
40 percent less likely to catch influenza than the control group. Overall, vitamin D appears to improve your immunity all across the board, and it may reduce your risk of contracting all sorts of infectious diseases.
Since chronic inflammation is related to an overactive immune system, the immune-balancing effects of vitamin D may reduce inflammation throughout your body. In fact, the scientific community widely accepts that consuming the right amount of
vitamin D reduces inflammation even though the exact mechanisms behind this effect remain unknown.
A longitudinal study found that children who were fed high levels of vitamin D from infancy onward were
88 percent less likely to develop diabetes later in life. These results strongly suggest that proper vitamin D intake is one of the best preventive measures against diabetes.
When you don’t have enough vitamin D in your body, your pancreas may have trouble producing insulin, and your insulin sensitivity may rise. Both conditions lead to diabetes, and they can also make existing diabetes worse.
Children who don’t get enough vitamin D are
more likely to develop allergic conditions like asthma, dermatitis, and eczema. Substances called glucocorticoids help prevent asthma, and vitamin D may strengthen the effects of these anti-inflammatory compounds.
By boosting your immune system, vitamin D may reduce your risk of developing hypertension, multiple sclerosis, rheumatoid arthritis, autism, and Alzheimer’s disease.
