Natural Breast Enlargement Foods

Many common foods contain trace amounts of hormone-affecting compounds. In theory, a diet rich in estrogen-stimulating foods may influence the size and shape of breast tissue. An estrogenic diet could improve breast size by triggering hormonal responses similar to those seen in women who are pregnant or nursing. However, no studies have evaluated the safety or efficacy of a breast-enhancing diet. Because hormone-affecting foods may facilitate the growth of cancerous breast cells, women with a history of breast cancer should avoid estrogenic diets.

Dairy Products

All dairy products contain estrogen, progesterone and prolactin, three hormones involved in lactation in all mammals. Common dairy foods such as cheese, milk and yogurt may stimulate breast growth by increasing levels of these hormones in women.

Licorice

According to the U.S. National Institutes of Health, licorice can cause high levels of estrogen and prolactin, two breast-enhancing hormones. Folk herbalists frequently recommend licorice as a holistic treatment for menopause and low breast milk supply, but these uses have not been thoroughly evaluated by modern science. Natural licorice candies are an excellent source of breast-stimulating compounds, but artificially flavored products are unlikely to affect hormone levels.

Fennel

According to a 1980 study published in the "Journal of Ethnopharmacology," fennel has a long-standing traditional use as a galactogogue, or breast milk stimulant. The journal reports that three primary compounds--anethole, dianethole and photoanethole--are responsible for fennel's notable effect on human hormone levels. Fennel is a popular Mediterranean table vegetable and may be used as a seasoning.

Fenugreek

Another traditional galactogogue, fenugreek is a key component of South-Asian cuisine. According to lactation consultant Kelly Bonyata, fenugreek increases levels of oxytocin, a hormone involved in breast milk production. It may increase a woman's breast size by mimicking the hormonal conditions typically seen in lactating mothers.

Soy

Minimally processed soy products such as tofu and edamame contain respectable quantities of isoflavones, which are chemically similar to estrogen. The U.S. National Institutes of Health acknowledge that soy may increase breast size, but that the use is based solely in tradition and theory.
