" The most active source of vitamin A is Retinal, and it's the most useful. "Vitamin A plays a very important role in your vision, bone growth, reproduction, cell division, and cell dieterentiation which is the process by which a cell derides what is going to become." On top of this vitamin A helps the body and the immune system. It determines whether your immune system will work fast or slow. The immune system fights off diseases and infections. Lack of Vitamin A may bring about many deficientcys in your body. Some foods containing vitamin A are Beef, liver, cheese pizza, and whole white milk.
Another vitamin that is important to remember while preparing food is Vitamin D. "the main job of Vitamin D is to maintain a normal blood level of calcium and phosphorus." Without this vitamin you are liable to be exposed to diseases such as rickets (a bone disease) and asleomalaria (muscular weakness and weak bones.) The elderly are recommended to have more intake of vitamin D than normal. Those who do not have much sun exposure should have an increased intake of vitamin D also. Foods containing vitamin D are fatty fish, fish oils, milk, eel, and cereal grain bars. Although vitamin D is very good for you it can become a problem if you consume too much. If a person consumes too much vitamin D they may experience nausea, vomiting, poor appetite, high blood pressure, and heart problems.
In order to get the maximum amount of vitamins out of your food you must do several things. You must soak and wash vegetables in order to preserver the vitamin B and C they contain. For example if you are making salad you should prepare close to the time you are going to eat it. You should store your meats at a temperature of 0 degrees in order to preserve the quality of meat and prevent bacteria growth. If you boil your vegetables in a bag they will maintain more vitamins than they would if you were to boil them without a bag.
