Exercise 6. Read and translate the text:

Vitamins and Minerals

A vitamin is an organic compound required as a nutrient in tiny amounts by an organism. In other words, an organic chemical compound is called a vitamin when it cannot be synthesized in sufficient quantities by an organism, and must be obtained from the diet. If a molecule can be synthesized in the body, it is not a vitamin. The single exception to this rule is vitamin D which can be synthesized in the skin, but only when exposed to sunlight and Niacin (B3) which itself can be synthesized in the liver in small amounts.

Vitamins are classified as either water-soluble or fat-soluble. There are 13 universally recognized vitamins: 4 fat-soluble (A, D, E, and K) and 9 water-soluble (8 B vitamins and vitamin C). Fat-soluble vitamins are stored in the body's fatty tissue, so they do not need to be ingested every day. Water soluble vitamins cannot be stored and must be ingested frequently for optimal health. They are easily excreted through the urine.

Vitamins have diverse biochemical functions. For example, vitamin A helps to develop and maintain body tissues such as bone and skin; it also helps the body’s vision. Vitamin C helps form tissues, cells, bones and teeth and improves the immune system’s performance.

Along with vitamins human body needs a certain amount of minerals. There are 20 minerals including copper, iodine, chromium, iron, tin, zinc, magnesium, sodium, potassium, chlorine, phosphorus, calcium, sulfur and others. They also have their own functions in the body. For example, copper is needed by enzymes for metabolizing; iodine assists the thyroid gland in working properly; calcium and phosphorus build bones and teeth; iron delivers oxygen to the body’s cells, and so on.

Vitamins and minerals not only help the body function, but they work to strengthen each other. The body absorbs iron through the help of vitamin C. Vitamin D helps the body absorb phosphorus and calcium.

A diet naturally high in vitamins and minerals can be the best defense against many diseases. You can develop health problems if you do not get enough of a particular vitamin. It is good to know thatfat-soluble vitamins should be taken before meals, and water-soluble ones should be taken after meals.

 

Exercise 7. Answer the questions:

1. What vitamins can be synthesized in the body?

2. How are vitamins classified?

3. How many vitamins are universally recognized?

4. Why is it unnecessary to ingest fat-soluble vitamins daily?
