The importance of vitamins for our health can hardly be overestimated. Probably, everyone has heard that vitamins and minerals are part and parcel of a healthy diet. Unfortunately, statistics says that today people all over the world consume too much calories and too little essential nutrients and vitamins.
Lack of vitamins, known as vitamin deficiency, influences the state of our skin, hair, nails, teeth and bones.
In more serious cases it can cause heavy diseases – spasms, loss of hair and teeth, loss of vision, hepatic disorders, skin diseases, and many others.
There are over thirty vitamins, and some of them are incorporated into groups. Vitamins themselves don’t have any nutritional value, they don’t contain any calories and can’t serve as sources of energy. They relate to micronutrients that are contained in food. So, to be healthy, we need to eat several types of food: fruit and vegetables, fish and meat, and milk products.
Vitamins can be divided into two large groups: fat-soluble and water soluble ones. As the term suggests, water soluble vitamins are dissolved in water, while the fat-soluble ones are dissolved only in fats. The first group includes vitamin C and B-group vitamins. Such vitamins as A, E, D and K belong to the second group, and they can be stored in our organism. That’s why we lack vitamins of the first group more often.
Vitamin B9, which is also known as folic acid is a very important element for women. It is absolutely indispensable during pregnancy and breastfeeding. Also it regulates nervous system activity and helps to combat depression.
It can be found in green vegetables, liver, wholegrain bread, honey.
Vitamin E (Tocopherol), is found in vegetable oil, green leafy vegetables, wheat germ, egg yolk, butter and liver. It functions as an «antioxidant» for other vitamins, preventing C and A and other fatty-acid proteins from being burnt up prematurely; in this way it helps prevent cell-membrane damage.
Most experts believe that Vitamin E deficiency can only occur in extreme causes of malnutrition, but this doesn’t mean that supplements might not be useful. One recent study found that Vitamin E helped to prevent angina (cardiovascular distress), for reasons not yet understood.
So, if you wish to be healthy, energetic and have a healthy appearance, pay careful attention to your diet. Try to choose natural food containing all basic vitamins and minerals. Your daily ration must include enough fresh fruit and vegetables, crude oil and wholegrain bread. Also try to eat fish or sea products at least twice a week.

Presentation on theme: «Vitamins.»— Presentation transcript:
2 Quick Facts: Vitamins are found in nearly all foods in the food pyramid. Vitamins are chemical substances found in food that are required for normal growth and health. Adequate intakes protect people from deficiency disease and may help prevent chronic diseases. Eating AT LEAST 5 fruits and vegetables daily is a good way to ensure adequate vitamin intake.
3 What are Vitamins? They are complex organic substances vital to life.
They are essential nutrients because usually the body cannot produce them or produce enough of them without adequate dietary intake. They are needed in small quantities. See the chart on page 161 to see the RDA
4 What are Vitamins? The first vitamin to be discovered was vitamin A in 1915. Most vitamins are not produced by body and must be consumed on a regular basis to remain healthy.
5 Role of Vitamins: Do NOT provide energy but regulate body chemistry and body functions. Many act as co-enzymes in the conversion of proteins, carbohydrates and fat into energy. May act as co-enzymes in reactions that build or maintain body tissues.
6 Role of Vitamins: May act as antioxidants, helping to prevent disease.
Thiamin is needed for reactions that convert glucose to energy. Folate is needed to help build body proteins.
7 Water soluble vs. Fat soluble
Those that dissolve in water are the B complex vitamins and vitamin C. Those that are soluble in fat are A, D, E and K. The water soluble vitamins can be stored in the body in only small amounts.
8 Water soluble vs. Fat soluble
Deficiency can develop within a few weeks to several months in cases of water soluble vitamin deficiency in the diet. Niacin, B6, and Vitamin C are known to cause bad effects if consumed in excessive amounts. Fat soluble vitamins are stored in body fat, the liver and other parts of the body. Deficiencies take longer to develop if there is dietary deficiency.
9 Dissolves in Fats or lipids

10 Vitamin B1 (Thiamin) Vitamin B1 is needed for the metabolism of carbohydrates. Vitamin B1 is also involved in the transmission of high-speed impulses in the nervous system. Found in: Yeast, peas, pork, wheat germ and peanuts.
11 Vitamin B1 (Thiamin) Vitamin B1 prevents Beriberi
Disease of the nervous system. Causes partial paralysis of the arms and legs, weakness, mental confusion.

15 Vitamin C (Ascorbic acid)
Vitamin C is present in all citrus fruits, potatoes, and cabbage. Must be consumed on a daily basis The main function of vitamin C is to assist in forming collagen and forms the hard layer of dentin in the teeth. Probably does not prevent the common cold; possibly may decrease the duration & symptoms.
16 Fat-Soluble Vitamins Stored in body fat, the liver, and other areas
Stored for longer times than water-soluble vitamins, so deficiencies take longer to develop than with water-soluble vitamin deficiencies “DEKA”
17 Vitamin A (Beta-carotene is its precursor)
The active form of vitamin A in food is called retinol. Found in animal products such as dairy products, eggs; fortified cereals, pumpkin, sweet potatoes, carrots spinach, parsley
18 Vitamin A (Beta-carotene is its precursor)
Vitamin A is essential for good vision and to maintain mucous membranes. Vitamin A also affect the length which bones grow and manufacture red blood cells. The body can store a year’s supply of vitamin A in the liver. Which allows the body to go long periods without adverse effects.

22 Rickets Rickets, a softening and bending of bones in children, first described in 1651, is another nutritionally-specific disease. It reached epidemic proportions following the industrial revolution, which began in the 1750s. In the 19th century, before the importance of exposing children to sunlight was recognized, the majority of children that lived in cities with sunless, narrow alleyways and pollution developed rickets. An autopsy study done in Boston in the late 1800s showed that more than 80% of children had rickets.
23 Vitamin E (Tocopherol)
Vitamin E is actually eight different chemicals Found is primarily in vegetable oils, but small amounts are present in fruits, vegetables, grains. Vitamin E helps stabilize cell walls
24 Vitamin K Important to blood clotting, aids in calcium absorption into bones, prevents bruising The human body cannot produce vitamin K but a bacteria in the intestine can produce this chemical.
