Слайд 2: NUTRITION AND HUMAN HEALTH

A healthy body needs healthy nutrition. Nutrition: the science which deals with the study of nutrients and food and their effects on the nature & functions of organisms under different conditions of age, health and disease. Good nutrition is an important part of leading a healthy lifestyle. Combined with physical activity, your diet can help you to reach and maintain a healthy weight, reduce your risk of chronic diseases (like heart disease and cancer), and promote your overall health.

Слайд 9: SOCIAL PROBLEMS OF NUTRITIONAL BIOTECHNOLOGY

Genes inserted in the genetically modified food may get immune to the pesticides and insecticides with time. In the case of certain people, the immune system may not tolerate the desired genes inserted through genetically modified food. This may result in diseases getting immune to antibiotics and drugs. Studies are also going on to verify if the consumption of genetically modified food may cause cancer. Some scientists are concerned that genetically modified food may create new allergens. The genetically modified food may produce new proteins which may act as a new allergen leading to allergic reactions in human beings and the entire food chain

VITAMINS: Vitamins are organic compounds that are needed in small quantities to sustain life. Most vitamins need to come from food. This is because the human body either does not produce enough of them, or it does not produce any at all.

Слайд 14

AVITAMINOSIS: Avitaminosis is a clinical condition caused by the lack of vitamins. The symptoms of lack of vitamin depend on the particular type of vitamin. Vitamin deficiency can be caused by poor diet; the most common cause of avitaminosis is the lack or insufficient quantity of fresh and varied food. Exclusive consumption of foods preserved or cooked at high temperatures; cooking inactivates some vitamins. Deficient intestinal absorption, which could be due to many different factors. Increased vitamin requirements; there are physiological situations (pregnancy, lactation, and during active growth in children) and diseases (hyperthyroidism, fever) in which vitamin requirements are increased, and their normal intake is not enough to satisfy the body’s requirements. Unbalanced diet; excesive ingestion of carbohydrates increases the requirements for vitamin B1. Excessive alcohol ingestion interferes with the absorption of several vitamins.

Слайд 15

Hypovitaminosis : A disorder that is caused by the deficiency of a vitamin. The deficiency may result from either suboptimal vitamin intake or conditions that prevent the vitamin's use or absorption in the body. Examples include beriberi caused by thiamine deficiency, scurvy caused by vitamin C deficiency, and rickets caused by vitamin D deficiency.

Слайд 16: FOOD ADDITIVES

Substances that are added to food to maintain or improve the safety, freshness, taste, texture, or appearance of food are known as food additives. Some food additives have been in use for centuries for preservation – such as salt (in meats such as bacon or dried fish), sugar (in marmalade), or sulfur dioxide (in wine ).

Слайд 17: PROBLEMS OF USAGE OF FOOD ADDITIVES IN FOOD INDUSTRY

It is often the additives that are used to give a food a marketable quality, such as colour, that most commonly cause allergic reactions. Some of these hypersensitive reactions include: Digestive disorders – diarrhoea and colicky pains Nervous disorders – hyperactivity, insomnia and irritability Respiratory problems – asthma, rhinitis and sinusitis Skin problems – hives, itching, rashes and swelling.
