Nutrition is the basis of our health, and we can prevent the incidence of disease through reasonable diet. Survey shows that focusing on nutrition could reduce the cancer incidence by 30% to 40%. But people often have some misconceptions in nutrition, now I will correct them for you.

Mistake One: The nutrient of great demand is not the most important one.
From the types, we need more than 40 kinds of nutrients in different degrees. For example, common people need to take in 60 to 90 grams of protein and 800 to 1000 micrograms of calcium every day. It is commonly known that protein is the important composition of our body and our immunity depends on it; while the calcium of little amount also plays unique role in the growth of bones.

Mistake Two: The more nutrition people take, the better effect it has on body.
Body could not lack nutrients, but it does not mean the more, the better. Here I just list protein as an example. If the children could not take in enough protein in their growing process, it will influence the normal development of height, weight, intelligence and some other aspects. However, ...
... the excessive intake of protein increases the protein decomposition and dispels more nitrogenous substances to increase the burden on kidney, accelerate the loss of calcium in bone and worsen the risk of getting osteoporosis.

Mistake Three: Foods can be divided into good and bad categories.
Some foods are said to be junk foods while some are praised as perfect foods. This is absolutely wrong. From the aspect of nutrition, we divided foods into five categories: the first one is cereal and potato; the second group is animal food; the third group is nuts; the fourth one is vegetable and fruit; and the last one is pure energy food. Every category of them could provide the necessary nutrients our body needs.

Mistake Four: The more expensive foods contain better nutrients.
An egg could provide more energy than an abalone. The protein content of them are almost the same; the fat and cholesterol contents of egg is higher than abalone; the carbohydrate content of abalone is twice than egg; the calcium, iron and selenium quality in abalone is better than egg. From the data, we can see that the nutrients of these two foods have no big difference and their contents of single nutrients are different.

In a word, we should learn to keep balanced dietary structure and do not be too picky in eating foods.
