Abstract
Skin is continuously exposed, more than other organs, to exogenous and endogenous substances that can modify its conditions and functions. Currently there is a great deal of literature pinpointing the close connection between some dermatological diseases and food. Good nutrition is a fundamental building block of good general health and healthy skin
Overnutrition or malnutrition and alterations of absorption or metabolism are at the basis of some very common skin diseases. Diet has an important role to play in many skin disorders, and dermatologists are frequently faced with the difficulty of separating myth from fact when it comes to dietary advice for their patients.
Dermatologic disorders in which diet has a definite role as dermatitis herpetiformis.Dermatologic etiopathogenesis disorders in which diet has a probable role is: atopic dermatitis, acne vulgaris, psoriasis vulgaris, pemphigus, urticaria, pruritus and allergic contact dermatitis.Dermatologic disorders in which specific factors in the diet are directly implicated in the etiopathogenesis of the disorder as Fish odor syndrome, toxic oil syndrome and fixed drug eruption. Miscellaneous disorders with an uncertain relationship to diet are: rosacea, vitiligo, aphthous ulcers, cutaneous vasculitis and telogen effluvium.
Recently diet is uniformly regarded as a major cause in the pathogenesis of acne. We reviewed the upto date literature regarding acne and culprit foods such as dairy products, chocolate, and fatty foods. There has been a reappraisal of the diet and acne connection because of a greater understanding of how diet especially low glycemic diet may affect endocrine factors involved in acne.
It is worth noting that in a review of the literature regarding the relationship of nutrient intake and the skin, particularly the photoprotective effects of nutrients, the influences of nutrients on cutaneous immune responses, and therapeutic actions of nutrients in skin disorders, it was found found that supplementation with the nutrients of focus (i.e., vitamins, carotenoids, and PUFAs) found in fruits and vegetables rendered protection against UV light. Oral supplements should be combined with sunscreen use and sun avoidance. Antioxidants impart wide ranging ameliorative effects; it appears likely that greater benefits are bestowed by the synergistic activity of several antioxidants. For example, the oral supplement consists of a combination of, alpha lipoic acid, vitamm C, tomato extract, pine bark extract, vitamins E, B, niacin, omega 3 fatty acids, polyphenols, soya extract, zinc, and copper, that has demonstrated clinical efficacy in the treatment of cutaneous aging symptoms as fine and coarse wrinkles, roughness, and telangiectasia.The role of vitamin D which plays a significant role in psoriasis treatments, including the drug Dovonex .Like all antioxidants, vitamin D exhibits the capacity to decelerate aspects of cutaneous aging. Oral Vitamin D supplementation in place of UV exposure appears to be the safest approach, for individuals at high risk for skin cancer (e.g., those who have red hair and freckles, or a family history of skin cancer) and the relation between vitamin D and hair cycle.
Life style and habitual dietary intakes have a significant effect on the skin. Accordingly, some dietary needs or restrictions can be categorized by skin type such as in dry skin increase omega 3 fatty acids, in oily skin increase green leafy vegetables and in sensitive skin increase fish, for vegans add flaxseed oil to the diet, for vegetarians derive the majority of fat from whole foods nuts, seeds, olives, avocados, and soy. Finally well planned vegetarian and vegan diets can met all these nutrient requirement for better health and healthy skin.
