Acne is an inflammatory condition in which clogged pores lead to pimples, whiteheads and blackheads. According to women's health expert Christiane Northrup, M.D., numerous factors contribute to acne during youth and adulthood, including stress, hormonal imbalances and nutrient deficiencies. In addition to proper hygiene and medical treatments when necessary, a diet based on particular nutrient-rich foods may help prevent or alleviate acne outbreaks. Seek your doctor's approval before making significant dietary changes.

Complex Carbohydrates

Complex carbohydrates, such as whole grains and starchy vegetables, provide rich amounts of vitamins, minerals, dietary fiber and glucose, the body's primary energy source. Complex carbohydrates are also low-glycemic, which means they have a lesser impact on blood sugar levels than refined carbohydrates, such as white flour and sugar-based foods. Low-glycemic foods can help prevent and reduce the occurrence of acne, according to women's health expert Christiane Northrup, M.D., by restoring healthy blood sugar levels and promoting proper hormone balance. To adapt to a low-glycemic diet, replace refined carbohydrates, such as enriched breads, pasta and cereal, instant rice, candy, cookies, chips and cookies with complex carbohydrates most often. Examples of nutrient-rich complex carbohydrates include 100 percent whole-grain breads, pastas and cereals; quinoa, barley and wild rice; long-grain brown rice; air-popped popcorn; winter and butternut squash; and sweet potatoes and baked potatoes. Consume complex carbohydrates as part of a healthy, balanced diet for best results.

Fruits and Vegetables

Fruits and vegetables provide significant amounts of nutrients, including vitamins, minerals and antioxidants. They are also rich in fiber and water. Due to the anti-inflammatory properties of fruits and vegetables, they may help prevent acne, according to author and medical expert Nicholas Perricone, M.D. In his book, "The Clear Skin Prescription: The Perricone Program to Eliminate Problem Skin," he lists the following fruits and vegetables as particularly helpful: apples, asparagus, bean sprouts, berries, Brussels sprouts, broccoli, cabbage, cauliflower, celery, kale, red bell peppers, honeydew melon, spinach, cauliflower, pears, Chinese cabbage, pomegranate and others. Consume a variety of fresh, colorful fruits and vegetables to reap the broadest wellness benefits. Frozen fruits and vegetables without added sugar, and canned fruit stored in natural juices, provide valuable secondary options.

Fatty Fish--Omega-3 Fatty Acids

Omega-3 fatty acids are healthy fats the body requires but does not produce; thus, you must obtain them from food. In addition to supporting cardiovascular health and brain function, omega-3 fatty acids can prevent and alleviate inflammation. For this reason, Dr. Perricone suggests regular intake of omega-3 fatty acids. Fatty fish, such as Alaskan salmon, albacore tuna, herring, mackerel, lake trout and sardines are prime sources of omega-3 fats. If you do not consume fish regularly or at all, you can reap similar benefits from certain plant-based foods, including ground flaxseeds, flaxseed oil, walnuts, walnut oil and canola oil.
