Obesity in children is generally related to diet. Too many kinds of food and too few kinds of food are important reasons for childhood obesity. Generally speaking, if children eat too many foods with high fat content or high sugar content, the probability of obesity will far exceed that of other children. Some children lack physical exercise and exercise too little. A few children are caused by genetic factors. If their parents are obese, the obesity rate of their children will be higher.
To prevent childhood obesity, we should pay attention to both diet and exercise. Usually, children should eat more fresh fruits and vegetables, eat less fried food with high sugar content, strengthen physical exercise, and let them take a walk after meals, which can improve their physical function and lower their blood lipids.
