Nutrition common mistakes

Investigation shows, pay attention to nutrition can make cancer reduced by 30% - 40%, but in fact, there are widespread misunderstanding of nutrition.

Misunderstanding one: the need of nutrition is important From the types, we need 40 more nutrients, some more, some less, and some are in grams remember, some is in micrograms remember. Such as protein, ordinary people need 60 - 90 grams, heavy manual workers need a. Calcium needs 800 - 1000 mg, iron 15 - 20 mg. But we don't need much less important, not important? Of course not, such as protein needs tens of grams, it is important for our body, we need the support of the immunity protein; and 15 milligrams of iron deficiency, iron deficiency anemia can also form etc, affect the child's development. Misunderstanding two: nutrition is not the more the better "Nutrition" cannot lack, but not the more the better. The protein as an example to illustrate the importance of "nutrition" right amount. The growth and development of children if the protein intake is not enough, it will affect the normal development of height, weight and intelligence etc.. So many people in addition to food intake of protein, eat a little protein powder. But in fact, protein and not the more the better, eat more means wasting, excess protein metabolism. Moreover, excessive intake of protein, increase in protein decomposition, excreted in the urine of nitrogenous substances also increased, will increase the load accelerated kidney, bone calcium loss, increase the risk of osteoporosis. Misunderstanding three: food is divided into good and bad We often hear some experts point of view, the food is divided into good and bad. Some foods are said to be junk food, some are called bag manufacturer universal food. This is not the correct view. In nutrition, we divided the food into five categories, the first is the cereals and tubers, second kinds of animal foods, third class is grains and nuts, vegetables, fruit is fourth class, fifth class is pure energy food. They each class can provide us the body needs nutrients. Misunderstanding four: food more expensive. Food is not more expensive the better. An egg to provide energy than a high protein content of abalone, almost, egg content of fat, cholesterol than high carbohydrate content of abalone, abalone is two times more than the egg, calcium, iron, selenium abalone is much better than the egg, but the egg in the vitamin A, B1, B2 than the abalone, niacin, vitamin C content almost, neither Data from the point of view, nutritional ingredients abalone and egg is not much difference, but the content of individual nutrients vary, but the price difference is big. A price can be bought a few jins of abalone egg, so more and more nutrients bag factory than the more expensive food.
