Should You Sip Soymilk to Improve Your Skin Health?
Ankeny, Iowa, January 9, 2018— A new clinical study from Japan draws attention to one of the lesser-known potential health effects of consuming soyfoods: the benefits of soy for skin health. Results of this study are consistent with previously published research. For this latest study, postmenopausal women consumed one cup of soymilk a day for eight weeks. The women filled out facial skin questionnaires three times—at the beginning of the study, eight weeks after consuming the soymilk, and four weeks after they were no longer consuming soy—answering questions about the condition of their facial skin. Questions covered dryness, elasticity, moisture, coarseness, pigmentation, and overall satisfaction.
At the beginning and end of the study, samples were also taken of skin underneath the forearm from each study participant. After eight weeks of drinking soymilk, the results showed that for all six questions, the condition of the skin significantly improved. Furthermore, the skin samples taken from underneath the forearm also were consistent with the improvements reported by the women themselves. With possible skin scores ranging from a low of 2 to a high of 10, at the beginning of the study, the skin score was approximately 4, whereas at the study’s conclusion, it was approximately 8. After four weeks of abstaining from soymilk, questionnaires indicated that most of the benefits were lost. That is, the condition of the skin approached the condition at the beginning of the study.
An important strength of this study is that the changes in skin health were determined both subjectively (questionnaires) and objectively (skin biopsies). Also noteworthy is that just one serving of soy per day led to such pronounced benefits.
In addition to offering potential benefits for skin health, eating soyfoods may also reduce the risk of developing heart disease and some forms of cancer, including breast cancer. One serving of soy offers approximately 7 to 15 grams of high-quality protein but not the large amount of saturated fat that typically comes with animal sources of protein.
