A new study supports the growing evidence of soy’s skin health benefits.


From helping to prevent age-related diseases, like osteoporosis, to serving as an important ingredient in cosmetics, soy is often seen as one of the keys to looking and feeling younger. And the evidence that soy foods support healthy aging continues to grow. A recent clinical trial found that consuming soy protein can help improve wrinkles, pigmentation and hydration.

The trial, a peer-reviewed study conducted by scientists from Integrative Skin Science and Research in Sacramento, California, commissioned by Soy Nutrition Institute (SNI) Global, and funded by the United Soybean Board, found postmenopausal women who consumed 30 grams of soy protein daily for six months experienced a decrease in wrinkle depth and pigmentation and an increase in skin hydration.

Beauty and Beyond: Reaping the Health Benefits of Soy Foods

These results are likely the result of soybeans being a significant source of isoflavones, which are naturally occurring plant compounds.

You can enjoy the benefits of soy isoflavones by adding more versatile soy foods, such as soymilk and tofu, into your diet. Indeed, the amount of isoflavones women consumed for this study can be found in just two servings of soy foods per day, such as two cups of soymilk or one cup of tofu. Offering all nine essential amino acids, soy protein is also an element of many common snack foods.

The health benefits of soy foods are more than skin deep. Evidence suggests that soy can alleviate menopausal hot flashes and may improve memory in older women. In addition, the amount of soy protein provided in this study has been extensively tested and (consistently) demonstrated to support heart health by lowering blood cholesterol levels.

Eating more soy foods is an enjoyable and accessible path to improved skin health and overall health. See our Soy Ingredient Index for more information on where you can find soy foods.
