Nuts
Nuts are high in a variety of nutrients, including fiber, heart-healthy fats, and minerals such as folic acid, selenium, and magnesium. Furthermore, some research suggests that some varieties of nuts may lower testosterone levels. Walnuts and almonds boosted levels of sex hormone-binding globulin (SHBG) by 12.5% and 16%, respectively, in a short trial of 31 women with the polycystic ovarian syndrome.
SHBG is a protein that binds to testosterone, causing a drop in free testosterone levels in your body. Nuts are also strong in polyunsaturated fatty acids, which have been linked to lower testosterone levels in several studies. Regardless of these findings, additional study is required to discover how certain types of nuts may alter testosterone levels.
