In this video, we’re going to talk about why vitamin D lowers your cancer risk—unless you are obese. Twenty-five thousand people were a part of a study on vitamin D that spanned over five years. Each participant was given 2000 IUs of vitamin D daily. This study showed that having healthy levels of vitamin D can lower your risk of cancer by 20%.
However, this was only for those who were not obese. The question is, why doesn’t vitamin D have the potential to decrease the risk of cancer for those who are obese?
The answer has to do with vitamin D resistance. The more obese you are, the more resistance you have to vitamin D. This is also connected to insulin resistance.
Vitamin D has a hard time working in the body if you are overweight. So you often need much more of it to produce significant results.
This is also why overweight people who get plenty of sunlight are often still deficient in vitamin D. Vitamin D has powerful anti-inflammatory properties. When you don’t have enough vitamin D, you can have an overload of inflammation, which can significantly increase your risk of cancer. This may be why obesity is linked to chronic low-grade inflammation and systemic dysfunction of the natural killer (NK) cells. How much vitamin D is ideal?
Typically between 10,000-40,000 IUs of vitamin D3 daily can help support normal vitamin D levels. Additionally, Healthy Keto and intermittent fasting can help you lose weight and lower your requirement for vitamin D.
