What you eat can have a great impact on your skin too. A poor diet has been linked to several skin issues. For example, dry skin may be an indication that you aren't consuming adequate fat. For dry skin, experts recommend eating more foods containing beta-carotene, zinc, vitamin H, omega-3 and omega-6 fatty acids, which can help strengthen your skin’s lipid barrier from the inside. Dry skin can occur because of skin dehydration, i.e. when the oil glands do not supply enough lubrication to the skin. More than 70 percent of our body consists of water – including your skin. Drinking plenty of water may help boost your skin’s moisture reserve and prevent skin dehydration. If you have dry skin, it's advisable to avoid anything that drains moisture from the body – such as alcohol, caffeine in coffee and tea, and excessive salt. Also avoid fried and baked foods as trans fats in these foods can constrict the veins and hinder blood circulation in the deeper layers of the skin. Other causes of dry skin include cold dry weather, food allergies, under active thyroid, and diabetes. Below are 5 best foods that can help combat dry skin.
