According to Commack based Dermatologist Valerie Goldburt, MD, PhD, what you eat not only goes straight to your hips, it’s also mirrored in your complexion. Proper nutrition can have a major impact on the way your skin looks and feels. Current research suggests that processed foods and high-fat dairy products can exacerbate acne, promote inflammation, and cloud a clear complexion. Other evidence indicates that foods high in protein and antioxidants (fruits and vegetables in particular) can have anti-aging effects.
The Latest Dietary Guidelines and Your Skin
In 2010, the United States Department of Agriculture released its latest Dietary Guidelines, while this year it released a new icon for healthy eating called MyPlate (www.myplate.gov). Both recommend that Americans eat more healthy foods such as fruits, vegetables, whole grains, fat-free and low-fat dairy products, and seafood. The guidelines also encourage people to consume less sodium, saturated and trans fats, added sugars, and refined grains such as white flour. No foods are off-limits, but the guidelines encourage portion control and calorie modification.
The data suggest that dairy products can be problematic for people with acne and other inflammatory skin conditions, so encourage our patients to limit milk and milk products to one or two services a day. These products may prompt the body to produce more of the male hormones, called androgens, which cause more oil and sebum that can clog pores. Additionally, dairy produced in non-organic farms may contain external hormones and pesticides, which can exacerbate skin conditions. We recommend eating calcium-rich vegetables such as spinach and collard greens to compensate for eating less dairy.
It also appears that following a low-glycemic diet is a key to clear skin. This is a diet that is low in refined carbohydrates and processed foods and high in produce and lean protein, which helps to keep the blood sugar stable. It’s been theorized that a high-glycemic diet can lead to insulin resistance, where the body needs to produce ever-increasing amounts of the hormone insulin in order to clear glucose (sugar) from the blood. Insulin resistance has been definitively linked to high blood pressure, diabetes, and heart disease, and there is evidence that it also leads to acne and more skin inflammation. Further research is needed, but a few studies suggest a benefit for acne in following a low-glycemic diet.
Following are recommendations for following the latest Dietary Guidelines and selecting foods that feed a clear complexion:
