But there are many ways achieve aesthetic benefits without a salon or a pill -- naturally, through the food you eat. We are constantly bombarded with new studies and articles telling us that the food we're eating is bad for our health. But there are some fruits and vegetables that have natural benefits, spanning beyond simply helping shrink your waistline.

Dr. Christopher Calapai Offers A Tip Sheet of Favorite Natural Skincare Options

HealthGrove identified five vitamins and minerals that support skin and hair health, based on multiple reputable journals and health sites, including the National Institutes of Health and WebMD. The health data site, part of the Graphiq network, then created a Healthy Hair and Skin Index on these micronutrients and found the 30 foods from their nutrition topic with the highest index scores. Data for nutrition information comes from ESHA.

After calculating the index, the list was pared to remove obscure foods. Ties go to the food with a higher "nutrient score," a rating developed by HealthGrove to evaluate the overall nutritional benefit of a food. It's calculated by dividing the "good" nutrient content of a food (such as vitamins, minerals and fiber) by the "bad" nutritional content (such as fat and sodium). HealthGrove also added a recipe as an example of how to cook each food.

Note: HealthGrove does not calculate the nutrient score of foods that have insufficient values for certain nutrients, reported by the USDA.
