The more researchers study the long-term effects of vitamin D on the body, the more they uncover its incredible benefits. Early research has linked vitamin D to various health perks, including stronger bones and a lower risk of multiple sclerosis, heart disease, depression, diabetes, and cancer. There’s even evidence suggesting that higher vitamin D intake can help with weight loss.
Although vitamin D isn’t a cure-all, it can significantly boost your overall health in ways most other vitamins can’t. Here are some reasons you should make sure you’re getting enough vitamin D.
### The Benefits of Vitamin D
Vitamin D comes from sunlight exposure, certain foods, and supplements. It’s crucial for our bodies, especially for bone development. In children, it helps build strong bones and prevents rickets, a condition that weakens bones and causes deformities like knocked knees and bowed legs. Thanks to the addition of vitamin D to milk in the 1930s, rickets became rare among U.S. children.
As we get older, vitamin D remains important for maintaining bone density by helping our bodies absorb calcium. Studies show that seniors who get enough vitamin D daily have stronger bones and are less likely to suffer fractures compared to those with low vitamin D levels.
Research also links low vitamin D levels to type 2 diabetes and obesity. While doctors don’t yet recommend vitamin D specifically to prevent diabetes, the evidence suggests it may benefit prediabetic individuals. In the case of obesity, studies indicate that those with higher body fat often have lower vitamin D levels because fat cells can trap the vitamin. Increasing vitamin D intake can help obese individuals, especially those on calorie-restricted diets, lose weight more effectively.
### How to Get More Vitamin D
Your body primarily gets vitamin D from sunlight. When the sun’s rays hit your skin, your body starts producing the vitamin. However, relying solely on sun exposure can be risky; insufficient sunlight can lead to vitamin D deficiency. While light-skinned individuals might get enough by spending just 10 minutes outside each day, seniors and people with darker skin don’t produce as much vitamin D from sunlight.
Besides, factors like cloudy weather, winter, and sunscreen use can limit your sun exposure. That’s why it’s important to also get vitamin D from food and supplements.
Most foods don’t naturally contain vitamin D, but fatty fish like mackerel, swordfish, and salmon are good sources and can provide a daily dose in one serving. Small amounts are also found in fortified cereals and milk, beef liver, and egg yolks. However, not all dairy products are fortified, so don’t count on cheese or ice cream for your vitamin D intake.
The best way to ensure you’re getting enough vitamin D is by taking a supplement. Nutritionists generally recommend 600 international units (IU) of vitamin D per day for adults up to age 70, and 800 IU for those over 70. However, it’s important not to overdo it, as taking more than 4,000 IU a day can be harmful.
In conclusion, making sure you get enough vitamin D is essential for overall health, especially for maintaining strong bones and possibly reducing the risk of several serious conditions. Consider a mix of sunlight, diet, and supplements to meet your daily vitamin D needs.
