Food storage Keep perishable foods tightly wrapped in refrigerator at a temperature slightly above 0 ° C. Avoid over frozen thawed products. In this case, lost a large amount of vitamins. Cooking does not digest and do not overdo the food, especially vegetables. Vegetables should be cooked so that they are slightly cracked. Roast the meat, stirring, over an open fire, cook for a couple or in a microwave oven. Use enough water so that nothing PS burnt. Serve prepared meals at sgol immediately after cooking (or be first in line at the cafeteria). Calculate the cooking time so that the dishes served were prepared at one time. Nutrients - antioxidants. Beta-carotene (provitamin of vitamin A), vitamins C and E and selenium (a mineral indispensable) function as antioxidants. Antioxidants are also many plant pigments, and a number of enzymes produced in the body. These substances prevent or compensate for damage caused by the cells of oxygen, ozone, smoke or other oxidizing agents. Lack of antioxidants in the body leads to premature aging, some cancers, bronchitis, heart disease, cataracts and complications during pregnancy. People who consume a day for five or more servings of fruits and vegetables have higher levels of antioxidants than people who eat them less. Other important components of food. In foods, there are many substances which are not mandatory for our diet, but nonetheless an important function in the body. We are just beginning to study the effect on health, such complex substances such as phenols. They are contained in the skins of grapes, wine, vegetable pigments (eg, alpha-carotene, lycopene, and leucine), as well as isoflavones in soy foods are. With regular consumption of these substances contribute to the prevention of certain infectious diseases, heart disorders and certain cancers. While we do not yet know how many of these substances is optimal. Recommended amount of nutrient intake if you're over twice the recommended rates of consumption, it is also safe. Malnutrition - the result of a lack, (pack and excessive intake of nutrients. For each nutrient there is a range of consumption, corresponding to the optimal functioning of the nutrient in the body. To some extent, the body can adapt to low or high intake of nutrients by using reserves or Conversely, displaying an excess amount in urine and feces. Diseases associated with inadequate intake of nutrients, or symptoms indicative of overdose occur when we exceed the body's ability to adapt to tsizkim or high levels of consumption. For example, if we consume too little vitamin C, the body resorts to the use of reserves of this vitamin, and when a stock is over, begin to show signs of failure. Symptoms of a lack of vitamin C may occur within a month. The first symptom is usually left unattended. If you do not start treatment, the gums begin to bleed themselves but currently appear bruises and bones to grow properly. Excessive intake of vitamin C (1 g or more) lead to diarrhea and likely contribute to kidney stones. Almost all cases of overdose of vitamins and minerals are the result of excessive use of food additives. Eating disorders can be caused by unbalanced diet or disease. People may have an eating disorder of the body due to inadequate or excessive intake of nutrients or due to bodily functions, weakened by a hereditary disease, surgery, illness or medication. For example, a bleeding stomach ulcer - a common cause of iron deficiency in older people. People with the disease, which causes the accumulation of too much iron to be suffering from an overdose of iron. The deterioration of body functions in people with cancer and AIDS often leads to malnutrition. Some groups of people are at greater risk to suffer from disorders in feeding, than others. risk from eating disorders in susceptible in different ways. If the need for nutrients is very high - during pregnancy, lactation, growth, illness, or recovering from illness or after surgery - Eating disorders of body cells develop faster than in healthy people during periods of food shortage. During the famine caused by war or natural disasters, public health, at risk to suffer more and more pronounced than others. The younger man during the forced starvation, and the longer this period, the more serious are the consequences affecting the health and mental development. Malnutrition can affect the development of certain chronic diseases. Lack of vitamins and minerals, as well as their surplus - it is not the only problems related to poor nutrition. Unbalanced diets play an important role in the development of heart disease, high blood pressure, osteoporosis, dental disease, complications of childbirth and other violations. In general, food with high animal Keeping fat and low _ ° 1tsei and fruits associated with the development of chronic diseases. sufficiency and balance - the main characteristics of a healthy supply. The ration of healthy eating is a lot of different products, which together provide sufficient calories and nutrients necessary for maintaining good health. The cornerstone of a balanced diet is variety, because no single product (except breast milk for infants) does not contain all the nutrients needed for our body. Most of the products not even close to coming to this ideal. A healthy diet based on foods rather than supplements, because there are many substances in the main product s power is not contained in food supplements. If choose between food and nutritional supplements, the preference should be given food.
