Psoriasis is a skin inflammation that affects millions of Americans. There is no cure, however, lifestyle factors, including stress management, topical medication and consuming a healthy diet rich in certain vitamins, including the antioxidant vitamins C and E, and B-vitamins (such as folate) may offer some protection against flare-ups.
Antioxidant Vitamins
Antioxidant vitamins, such as vitamins C, E, and beta-carotene (precursor to vitamin A) help to strengthen the immune system, and possibly offer protection against the development of this condition or decrease the intensity of symptoms. People who eat more orange, red and green vegetables and fruits appear to be less likely to develop psoriasis. Foods which offer the most antioxidant protection include carrots, sweet potatoes, sweet bell peppers, apricots, tomatoes and tomato products, citrus fruits and dark green leafy vegetables such as spinach and kelp.
Thiamin and Pantothenic Acid
B-vitamins are beneficial because they play a role in the repair and healing of skin tissue. One such B-vitamin is thiamin, also known as vitamin B1. The richest food source of thiamin is pork. However, wheat germ, sunflower seeds and whole wheat pasta are also very good food sources of this nutrient. Pantothenic acid (PA) is another B-vitamin that is essential for the health of your hair, skin and nails. Food sources of PA include avocados and bananas.
Folic Acid
Individuals suffering from psoriasis may have elevated homocysteine levels. Homocysteine is an amino acid compound found naturally in the bloodstream that can be toxic, and contribute to heart disease, when elevated. In a study published by the British Journal of Dermatology, researchers found that the higher the blood level of homocysteine (in those with psoriasis), the more severe the disease symptoms. However, folic acid (vitamin B9) levels were inversely correlated with psoriasis severity. Therefore, folic acid helps regulate and decrease homocysteine levels. Foods fortified with folic acid include breads and cereals. Foods rich in the natural form of folic acid (known as folate) include beans, legumes and dark green, leafy vegetables.
