In recent years, scientists abroad have observed and analyzed the age of menarche in girls from 30 countries and regions, and found that diet can influence the age of menarche, especially the fiber content in food.
For example, girls in London who consume less dietary fiber have an average age of menarche at 13 years old, while girls in Papua New Guinea who consume more dietary fiber have an average age of menarche at 17 years old. We know that the development of ovarian function and the secretion of female hormones require sufficient cholesterol. The cholesterol needed by the body is mainly obtained from food. The absorption of cholesterol from food depends on the fiber content. If the fiber content is high, then more cholesterol in the food can be excreted through the feces, reducing the absorption of cholesterol. This can lead to a reduction in the synthesis of female hormones in girls. The reduction in the synthesis of female hormones also affects the development of reproductive organs such as the uterus, delaying the age of menarche in girls. Therefore, girls should pay attention to their diet. They should not consume excessive amounts of food with high fiber content. They should also pay attention to the nutritional balance of their diet and eat moderate amounts of lean meat, fish, eggs, milk, poultry, and other foods that are rich in cholesterol. This is to promote the development and maintenance of sexual organs.
