On the one hand, the size of breasts is determined by genetic and physiological factors, such as race, mother and individual; On the other hand, it is influenced by acquired factors such as nutrition, exercise, hormone secretion and disease. The development of young girls' breasts is closely related to hormones in the body, and prolactin produced by the anterior pituitary gland directly acts on the breasts; Ovary produces estrogen and progesterone to promote breast growth; Growth hormone and insulin are also indispensable components of breast development.
Food nutrition is related to many factors affecting breast development, some of which are horizontal and some are vertical. Girls can't deliberately lose weight. For Tingting, first of all, we should eat more high-energy foods, such as high-fat foods, such as livestock, poultry, sesame, day lily, sugar, cakes and so on. Ensure that there is enough fat in the body. Because most mature breasts are fat, and glands only account for 1/3, the amount of fat determines whether the breasts are plump and elastic.
Of course, it does not mean that the fatter the better. Too much fat accumulation causes sagging breasts and affects the appearance of the body. Secondly, eat more foods rich in vitamin E, such as Chinese cabbage, cauliflower, sweet potato, pumpkin, almond, sunflower oil, cottonseed oil, rapeseed oil, soybean and peanut. Because vitamin E can promote the development and perfection of ovary, increase mature egg cells and luteal cells. Egg cell is an important place to secrete estrogen, which can promote the growth of mammary duct when estrogen secretion increases; Progesterone makes the mammary duct continuously branch to form mammary tubules, which makes the breast grow up. Third, eat more foods rich in B vitamins, such as animal liver, kidney, egg yolk, lean meat, eel, roe, milk and its products, cereals, beans, mushrooms, yeast and so on. Because B vitamins are indispensable ingredients for the synthesis of estrogen in the body.
In addition, there are some breast enhancement products, such as fermented filial piety, which is a natural hormone; The coating of seed nuts such as soybean, peanut, almond, walnut, sesame and corn can promote gonad development, among which corn is definitely the best breast enhancement food by nutrition experts; Sticky sea cucumber, trotters, tendons, etc. It is also a breast enhancement food, so you can eat more appropriately.
By the way, there is no absolute standard for breast size. Even if the breasts become smaller, don't be anxious and sad all day, because simple breast reduction will not affect future marriage and children. Usually after pregnancy, because pregnancy and breastfeeding can greatly increase the secretion of progesterone, then the chest will be full.
And do more chest-width exercises and massage yourself properly.
