VITAMINS ARE IMPORTANT TO GOOD HEALTH

Scientists have discovered kinds of vitamins. They are known as vitamins A, B, C, D, E and K. Scientists say vitamins help to carry out chemical changes within cells. If we do not get enough of the vitamins we need in our food, we are at risk of developing a number of diseases. Which foods should be eaten to keep us healthy? Let us look at some important vitamins for these answers.   

Vitamin A helps prevent skin and other tissues from becoming dry. It is also needed to make a light-sensitive substance in the eyes. People who do not get enough vitamin A cannot see well in darkness. Vitamin A is found in fish liver oil. It also is in the yellow part of eggs. Sweet potatoes, carrots and other darkly colored fruits and vegetables.

Vitamin B changes starchy foods into energy. It also helps the heart and nervous system work smoothly. Vitamin B is found in meat, fish, green vegetables, bread, egg and milk..

Vitamin C is needed for strong bones and teeth, and for healthy blood passages. It also helps wounds heal quickly. The body stores little vitamin C. So we must get it every day in foods such as citrus fruits, tomatoes and uncooked cabbage.

Vitamin D increases levels of the element calcium in the blood. Calcium is needed for nerve and muscle cells to work normally. It also is needed to build strong bones. Ultraviolet light from the sun changes a substance in the skin into vitamin D. Fish liver oil also contains vitamin D.

Vitamin K is needed for healthy blood. It thickens the blood around a cut to stop bleeding. Bacteria in the intestines normally produce vitamin K. It can also be found in pork products, liver and in vegetables like cabbage, kale and spinach.

Vitamins are important to our health. A lack of required vitamins can lead to health problems. Different vitamins are found in different foods -grains, vegetables and fruits, fish and meat, eggs and milk products. And even foods that contain the same vitamins may have them in different amounts. Experts say this is why it is important to eat a mixture of foods every day, to get enough of the vitamins our bodies need.
