You might find your skin becomes irritated after eating certain foods, particularly if you have allergies or sensitivities to some foods. Some foods can also exacerbate existing skin conditions such as eczema or psoriasis, so avoiding these foods can help lessen skin irritation. Conversely, some foods might actually be beneficial in helping to calm irritated skin.
Leafy Greens
Dark green leafy vegetables such as broccoli, spinach and lettuce might be effective in soothing irritated skin. In his book, "Burgerstein's Handbook of Nutrition: Micronutrients in the Prevention and Therapy of Disease," author Michael ZImmerman notes that leafy greens are rich in an array of different vitamins, including vitamins A, C, D, E and K. In addition, dark leafy greens also contain iron, calcium, fiber and folic acid, all of which can build up your body's immune system, and can also assist your body's production of collagen, a protein that helps keep skin healthy and maintain its elasticity.
Fish
According to Jack Challem in his book "The Inflammation Syndrome: The Complete Nutritional Program to Prevent and Reverse Heart Disease, Arthritis, Diabetes, Allergies, and Asthma," the omega-3 and omega-6 fatty acids found in many types of fish can have a beneficial effect on irritated skin. As Challem points out, one of the key symptoms indicating a deficiency in omega-6 and omega-3 fatty acids is dry, flaky skin. Adding fish or other foods containing these fatty acids to your diet can thus alleviate the symptoms of irritated skin.
Avocados
Avocados are a rich source of essential oils and B-complex vitamins, and has anti-inflammatory abilities. Because of these factors, eating avocados can soothe irritated skin. Avocados can also be used topically to treat irritated skin. According to the American Academy of Dermatology, vitamins B-3 — commonly known as niacin — and B-5 — also known as pantothenic acid — are effective at helping the skin hold moisture and are often added to natural skin-care products. As avocados contain both these vitamins, applying avocado directly onto irritated skin might help soothe and moisturize skin.
Oatmeal and Cornstarch
One of the most common ways to alleviate skin irritation is to soak in an oatmeal bath. According to MedlinePlus, one of the most effective — and all-natural — ways to calm irritated skin is to add oatmeal or cornstarch to a warm bath and soak irritated skin in this oatmeal-and-water mixture. An oatmeal bath can be particularly soothing for eczema and psoriasis, and can loosen scaly skin and calm the urge to scratch skin that is raw and itchy.
