A healthy diet affects skin conditions in the following ways:
Dietary intervention steers the course of the disease (acne)
Dermatological diseases are linked to systemic diseases; thus a regular diet affects the health in a positive way, leading to a favorable outcome (psoriasis)
A healthy diet can assist in preventing certain dermatological conditions (skin cancer, wrinkles)
Systemic medication (steroids) prescribed for dermatological conditions may increase the risk of other diseases. A regular diet helps reduce that risk
For example, in the case of food allergies, there is a direct relationship between diet and skin conditions.
Consumption of certain foods like chocolate, sea food, nuts dairy can lead to flare up of acne
A fruit and vegetable based diet, rich in antioxidants and vitamin C & E can reduce the risks of skin cancer; a diet rich in meat, and full fat dairy increases the risk.
A diet with high sugar content accelerates the rate of aging skin; herbs such as cinnamon, garlic, ginger, oregano & lipoic acid found in certain fruits and vegetables decelerates the rate of aging skin
Dietary intervention in psoriasis reduces the cardiovascular risk. A diet rich in fruits and vegetables, whole grains & omega 3 fatty acids is recommended.
