Nowadays, food safety is really a social problem, so purely from a nutritional point of view to explore what to eat to improve immunity is somewhat one-sided. There are a few more basic concerns or hope that we can have an understanding of: First, the nutritional comprehensiveness and balance is very important Although many articles on the Internet on the food pH and a certain group of vitamins and so on a lot of publicity, but I personally feel that a lot of research is aimed at adults, on the child is in the period of growth and development to speak of, the necessary protein intake, especially high-quality protein intake is very important for the body to synthesize a sufficient amount of immune cells and related factors; while vitamins and fiber are mostly found in fresh vegetables and fiber, and the immune system is very important. Cells and related factors is very important; and vitamins and fiber are found in fresh vegetables and fruits, please note that fresh, so a lot of vitamins are destroyed when stewed vegetables, in addition, many parents think that eating leafy greens is considered vegetables, but most children are not too much love to eat the younger, in fact, such as zucchini, tomatoes, cucumbers, eggplants, winter squash, sweet potatoes and so on are very beneficial and relatively easy to accept vegetables, and fruit is really not expensive, and the fruit is also not very easy to eat. Fruits are not as good as the expensive ones, but seasonal common fruits are more beneficial than imported or rare ones. Second, on the basis of the safety of choice In fact, I also consulted with many professional friends, hoping to understand which brands or which components of the food safer, but really lack of uniform answers, but there are a few points are certain: 1, non-processed natural state of the food is safer than processed: for example, bacon and fresh meat I personally would choose to buy fresh meat home to do it yourself, so the grilled sausage, ham, dim sum, a variety of juices, I still recommend eating fresh food in its original flavor. 2, and then nutritious things should not be fixed all the time to eat, including recognized nutritional food, like sea cucumbers, gelatin, honey, etc., a child is the body of the sun, do not recommend supplementing the same as the elderly, on the other hand, now the pure natural non-farmed things are relatively few, so despite the nutritional value of the clear, but also do not recommend a large number of supplements, or pay attention to the nutritional balance of what to eat, meat, eggs, milk, vegetables and fruits, which in fact do not do not have the same nutritional value. Vegetables and fruits, this is actually not easy to do, many children will still be partial to food, parents have to be more patient guidance.
