For example, if you say that too many people in poor communities have problems with alcoholism, you should ask yourself but why?. Once you come up with an answer to that question, probe the answer with another but why? question, until you reach the root of the problem, the root cause.
Vitamins, one of the most essential nutrients required by the body and can be broadly classified into two main categories i.e., water-soluble vitamins and fat-soluble vitamins. Water-soluble vitamins cannot be stored in the body, so you need to get them from food every day. They can be destroyed by overcooking.
However, the form of vitamin D used in prescriptions in North America is almost invariably vitamin D2. Basically there are two types of oral vitamin D supplements. The natural ones are D3, and they contain the same vitamin D your body makes when exposed to sunshine. The synthetic ones are vitamin D2, which are sometimes called ergocalciferol. Once either form of the vitamin is in your body, it needs to be converted to a more active form.
