Childhood is a critical moment for children's physical development and brain development. Children grow and develop rapidly and need to take in a variety of nutrients. Therefore, it is also the responsibility of every parent to supplement the nutritional needs in time. Below, let's take a look at what misunderstandings parents have in supplementing nutrition for their children: misunderstanding 1: dairy products will aggravate children's colds. The fact that dairy products can increase mucus production or thicken mucus secreted by nasal cavity is completely wrong. When a child has a cold, the mucus in his nose and throat is produced by the cold virus. And dairy products just stick to my throat, which makes people feel a little uncomfortable. When the child has a cold, you can continue to provide him with milk or other dairy products. If he doesn't drink milk, give him other liquids, such as boiled water, juice, porridge or chicken soup, until he feels better. Even if the child has no appetite, let him drink enough water to prevent dehydration and let his nose flow out of the nasal cavity. Myth 2: Children can't get the necessary vitamins and minerals without eating vegetables. The fact is that some children don't like vegetables, but they are still healthy. The reason is that they like to eat fruit. In the process of children slowly learning to accept green vegetables such as green vegetables and spinach, fruit is a good nutritional substitute. If your child doesn't eat carrots, in order to supplement vitamin A and carotene that may be lacking, you might as well give him some apricots or honeydew melons; Strawberries or oranges can replace spinach to meet children's demand for folic acid. Bananas can replace potatoes as a source of potassium; Citrus fruits can replace Chinese cabbage to meet the needs of vitamin C, but in any case, vegetables and fruits cannot completely replace each other. Vegetables are not only rich in essential vitamins and minerals, but also contain a variety of phytochemicals that promote health. Therefore, you must constantly provide your child with vegetables so that he can accept and like them. This is very important. Myth 3: In order to prevent obesity, children's fat intake should be restricted. The fact is that for infants and young children, their brains and bodies develop extremely rapidly, and 40% of their daily calories (calories) are taken from fat. The developing brain has special needs for fatty acids and other components in fat. Therefore, most experts suggest that children under 2 years old should drink whole milk instead of skim milk. Older children still need to get enough essential fatty acids from their diet, which is conducive to the healthy and normal growth of the skin, the secretion of sex hormones and the absorption of vitamins. But after 2 years old, it is enough to get about 30% calories (calories) from fat every day. In addition, the fat in food will make children feel full.
