Hello, thin children want to be strong, and need to check the causes of thinness, such as malnutrition caused by partial eclipse, which leads to slow development and thinness of children. For such children, it is necessary to enrich the dietary nutrition in an all-round way, and disperse the food types to every meal. It is best to have different meat for each meal, proper amount of eggs and milk every day, and vitamins and other nutrients in fruits and vegetables. The diet strictly controls the intake and effectively controls the intake of protein and other nutrients, which can help children supplement protein and other nutrients without excessive adverse effects.

In terms of drinks, don't let fruit juice replace water, because the sugar content in fruit juice is very high, which will increase the daily calorie intake. At the same time, fruit juice also lacks high protein and dietary fiber, so it is easy to drink hot sugar and lack appetite for normal food, which makes children dislike eating, leading to stunting due to malnutrition.

Therefore, the best drink for children is boiled water, followed by ordinary milk without adding sugar, which is not easy to cause obesity due to excessive sugar intake, and also allows children to reduce the amount of nutrition affected by drinks for three meals as much as possible.

If the child is short and thin due to genetic factors, all the members of the child are short and short, especially the immediate family members of both parents, it is difficult for the child to improve by supplementing nutrition or exercising. Of course, children also have atavism, and they will skip several generations and be similar in size to their ancestors. However, the hope is rather slim and cannot be pinned on this.

To sum up, there are many reasons for the thinness of children. It is recommended to find out the reasons and seek solutions. Food and exercise are only a means to help children develop, and they cannot solve all developmental problems.
