was posted on this blog on December 7, 2008 Papaya breast enhancement and beauty? In the post of this article, many people who have no physiological knowledge at all have made funny comments. Some male netizens judge that females can eat papaya for breast enhancement based on their itchy breasts after eating papaya; Not to talk about the problem of papaya milk. Therefore, I think it is necessary to give them some physiology (piggybacking some anatomy) lessons.

　　Women''s chest circumference is mainly composed of the following parts: the chest cavity and its skeleton (sternum, ribs, spine, etc.), muscle layer, fat layer, breast gland tissue, skin, etc.

　　 1. The size of the adult female’s chest cavity and its skeleton is very fixed, and generally does not become larger or smaller. The thickness of the skin layer is generally not significantly different or changed.

　　 2. The muscle layer is variable. Generally, the muscle layer can be thickened through exercise (especially targeted strength training), whether it is thickening the back muscles or the chest muscles. Thickness will increase the entire bust. Without exercise, diet alone will not increase muscle mass in any part.

　　 3. The fat layer is easier to change, the fat layer thickens when you gain weight, and the fat layer becomes thinner when you lose weight. When the chest fat layer is thickened, it is often mistaken for breast enlargement, but it is not. The bust of a fat woman increases (for example, from 70 to 80), but the size of the cup does not increase (for example, it does not change from A to B); conversely, when a woman loses weight, the bust can change from large to small (For example, from 75 to 70), but the cup will not shrink accordingly (for example, the cup changes from C to B). In other words, when losing weight or gaining weight, the breast tissue has not changed, only the fat layer under the breast (or chest) is changed.

　　 4. The development of breast tissue is determined by hormones in the body, and hormone levels can be changed due to puberty, pregnancy, disease, and medication, generally not because of food (except for hormones or contaminated by hormones) Or exercise and change. At present, there is no food (except those containing hormones or contaminated with hormones) that can change the level of hormones in the body and cause the development of normal breast tissue, which changes from small to large (such as the cup changes from B to C).

　　 In short, as far as adult women are concerned, the bust can be changed. If you gain weight, it can increase the bust and cause the illusion of breast enlargement. In fact, the increase is only the fat layer, not the breast tissue. To increase breast tissue, it is necessary (and only) to change the hormones in the body, such as the use of hormone drugs or cosmetics, certain diseases or pregnancy and other special circumstances. Food in general (except for food contaminated with hormones or containing hormones) does not have this effect. Papaya, walnuts, sesame seeds, red dates, lotus seeds... All foods that look like or do not like women''s breasts do not have such a function effect. "Breast-enriching food" is just wishful thinking, boring, and hopeless concept! Or, breast-enriching food is just "fat food".
