High levels of DHT and testosterone play a role in increasing acne development, according to an older 2009 paper. The treatment group also had decreased androgen hormone dihydrotestosterone (DHT) levels, which is related to testosterone. The research found participants receiving the isoflavone had significantly decreased acne lesions, or pimples, after treatment compared with the placebo group. Soy may have beneficial effects on the skin.Īn older study asked people to consume 160 milligrams of a compound from soybeans called isoflavone every day for 12 weeks. When the skin produces too much sebum, it may lead to acne. However, one review article found this vegetable and several other plant foods contained low amounts of leucine, an amino acid involved in sebum production. There is not much evidence on the direct effects of broccoli on acne. Sulforaphane may also help prevent premature skin aging by stimulating several protective processes in skin cells and promoting stem cell renewal. A 2019 study notes that they contain sulforaphane, which has antioxidant and anti-inflammatory properties. Broccoliīroccoli and other cruciferous vegetables have positive effects on skin health. Fatty fishįatty fish is a source of omega-3 fats, an essential part of the diet with several well-documented positive health effects.Ī 2020 review found that consuming omega-3 fatty acids, such as those found in fatty fish, helped manage inflammatory skin conditions, including:Īdditionally, including omega-3s in the diet reduces the likelihood of developing skin cancer and may also decrease the effect certain drugs have on the skin. To keep the skin at its healthiest and help reduce acne, consider increasing consumption of the following foods. However, following a diet consistently high in many of these foods may play a contributing role in developing acne. It is unlikely that any single food on this list can cause acne if a person eats them in moderation. Western diets tend to include foods with a high GI, including: When the body has excess insulin, it stimulates the production of androgen hormones and sebum in the skin, which can lead to acne. Research shows that diets with a high glycemic index (GI) may contribute to acne.įoods with a high GI raise blood sugar - and therefore insulin levels - faster than foods with a lower GI.Įating a diet with a high GI causes the body to produce more insulin. For example, according to an older study, dairy contains the amino acid leucine, which promotes the production of sebum in skin cells. Other components of milk products may also influence acne. This may be due to reduced amounts of estrogen in skim milk compared to whole milk. Some studies in girls and boys have shown that consuming dairy products, especially skim milk, was associated with having more acne. The hormone estrogen, for example, may actually reduce acne. In addition to IGF-1’s impact on hormones related to acne production, other hormones present in milk and dairy products may affect acne both positively and negatively. Since milk and other dairy products contain this hormone, it may explain a possible link between dairy consumption and acne. IGF-1 interacts with adrenal glands, affecting hormones in a way that contributes to acne. Limited research suggests that milk and dairy products might contribute to skin conditions, such as acne, in some people.Ī 2016 review suggests a link between high blood levels of the hormone IGF-1 and acne severity. If a person has concerns about acne or simply wants to make sure they are eating a diet for healthy skin, they may consider eating less of the following foods.
