Individual responses biochemical reactions

Research shows that some people need double or triple the amounts of certain substances, others may require forty times more than most people. Ration of 97% of people balanced, most experienced a significant lack of vitamins and minerals. Recall that the RDA standards were set as a minimum to ensure nutritional diseases such as scurvy, characterized by extreme exhaustion. However, with this spread needs, as outlined above, the average amount of nutrients (RDA) are useless. Individual biochemical response also will vary among people with different abilities of mastering power. For example, with age, gradually deteriorates the secretion of digestive juices and digestion in the intestine. Even with a best quality products to efficiently absorb incoming nutrients in them. Some people need extra nutrients to compensate for the weakness of digestion. Need for some power due to several factors, including: activity level, age, sex, stress, genetics, illness, and other factors. LEVEL OF ACTIVITY: The need for adequate nutrition in humans, leading a physically active life, higher than those whose lifestyles slow-moving. Inactivity has its consequences: contributing to the deterioration of the circulatory system, which reduces the efficiency of feeding cells. Physical exercise increases the need for good nutrition and improve the efficiency of metabolism. AGE: Growing children need different than adults, the structure of power. During the period of growth requires more fatty acids than adults, when the rate is calculated by weight. The boy on the verge of puberty will need much more zinc than a young man of 20 years. With aging, changes need for certain substances. The process of assimilation of food and drugs affect. Many elderly people are unable to absorb the nutrition they need from food. PAUL: different needs of men and women, girls and boys. For women, such as the need for some nutrients is determined by different periods of life: menstrual cycle, pregnancy, breastfeeding, menopause. Stress: physiological or emotional stress can have a significant impact on appetite, food choices and consumption of food. Stress increases the need for B - vitamins and minerals such as zinc and magnesium. Lack of magnesium is usually the cause of cravings for chocolate. In the confusion of our lifestyle and the piles,, little stress''is important to provide the body with additional nutrients, as these external factors substantially increase the need for good nutrition. GENETICS: Differences in requirements of nutrients (more or less than average) to a certain extent due to heredity. Unhealthy: Certain diseases significantly increase the level of nutrients the body needs to recover. Other factors: Many permanent habits affect the need for some food. Alcohol increases the demand for zinc, magnesium, vitamins B and C; smoking in vitamins C, B6, and zinc. Lovers of tea and coffee making facilities need more iron, vitamin B1 and zinc, as these drinks impair the absorption of iron and zinc, as well as the utilization of thiamine. With these bad habits are associated lung, pancreas, liver and digestive tract; they interfere with recycling of vitamins, minerals and trace nutrients. Prescription and over-the-counter drugs - laxatives, antacids, painkillers, antibiotics and oral contraceptives - often deplete the body, because they block, suppress and prevent the full utilization of food by the body.
