12 Delicious Foods to Support Skin Health

The skin is the largest organ of the body and serves to protect our body, regulate temperature, and manufacture vitamin D.

The health of your skin depends on the nutrients it receives. Feeding your skin from the inside is much more beneficial than any cream or beauty treatment you can buy.

Foods that promote skin health include oil fish, pomegranates, avocados, orange vegetables, turmeric, berries, nuts, fermented foods, chocolate, watermelon, spirulina, and seeds. Making these foods a regular part of your diet will give your skin an extra boost of nutrients and keep it healthy.

12 Foods to Support Healthy Skin

1Oily Fish (Salmon)
Salmon Fillets
Salmon and other oily fish are well known for being a top source of omega-3 fats, which have strong anti-inflammatory effects and moisturize skin from within, helping maintain elasticity and preventing dry skin. Pink fish such as salmon and trout contain a carotenoid pigment (from the same family as beta-carotene) called astaxanthin that has been shown in studies to reduce wrinkles and age spots and improve skin texture and elasticity (1). Salmon is also a great source of skin essentials selenium and protein.

2Pomegranate
Pomegranate
Pomegranates contain a substance called punicalagins, which has potent antioxidant and anti-inflammatory effects. Both oxidative stress and inflammation contribute to skin damage and aging, so anything that can reduce these benefits skin condition. One study found that pomegranate extract can protect skin fibroblast cells (the ones that produce collagen) against damage and death from UVA and UVB rays (2). Pomegranates are also an excellent source of vitamin C, and also for healthy collagen formation and essential skin vitamins A and E.
Nutrition Facts for Pomegranates.
3Avocados
Half an avocado
Avocados are a top source of vitamin E, which helps skin retain moisture and aids skin healing. Vitamin E is also an antioxidant, so it protects skin from the aging effects of free radicals (3). Vitamin E can help protect against sun damage and reduce inflammation in the skin, which is involved in acne, eczema and skin rashes. Avocadoes are also a great source of healthy monounsaturated fats and antioxidants, including carotenoids, both of which have been linked with improving skin health and appearance (4).
Nutrition Facts for Avocados.
4Orange Vegetables
Carrots
Orange vegetables such as carrots, butternut squash, pumpkin and sweet potatoes contain particularly high levels of beta-carotene. Beta-carotene is converted in the body to vitamin A, an essential nutrient for skin health and maintenance. It is needed for new skin cell formation, skin repair, and healing. Vitamin A also influences the ability of the skin to withstand environmental damage and helps prevent collagen breakdown. Beta-carotene itself has antioxidant effects and can help build up natural protection against the sun and reduce sun damage to the skin (5,6).
*Foods only offer relatively weak protection against sun damage and should never be a substitute for sunscreen and safe sun exposure, rather they should be an additional supportive measure.

5Turmeric
Slices of turmeric and turmeric powder
Turmeric - contains a substance called curcumin, which has potent anti-inflammatory and antioxidant properties (7). Its anti-inflammatory effects are beneficial for calming skin irritation such as acne flare-ups and in India turmeric is commonly used in facemasks. Turmeric also helps protect skin against aging, as it not only acts as an antioxidant itself but also boosts the activity of the body's own antioxidant enzymes, so its actions against free radicals are two-fold. In addition, turmeric supports liver detoxification enzymes, which have benefits for the skin and overall health.

6Berries
Strawberries and blueberries
Berries are rich in flavonoids, a type of antioxidant that protects the skin against free radical damage and aging (8). Strawberries, in particular, are also an excellent source of vitamin C, with 1 cup providing more than 100% of the RDA. Vitamin C is found in high levels in both the dermis and epidermis of the skin, where it has an essential role in collagen production. Collagen is the main structural protein of the skin, which keeps it strong, supple, and firm; its decline as we age causes skin wrinkling. Aging, UV light, and pollutants can lower the vitamin C content of the skin, so the more we get in our diets the better.

7Nuts
Nuts and Seeds in a Bowl
Nuts are one of the most nutrient-dense foods, being a top source of healthy fats, antioxidants, vitamin E, plant protein, and a host of beneficial phytochemicals. Nuts have anti-inflammatory and antioxidant actions, which can both help prevent skin aging. Nuts, especially Brazil nuts are also a top source of the mineral selenium, which can help reduce skin aging and possibly even reduce the risk of more serious skin damage (9). Selenium is also essential for the functioning of the body's inbuilt defenses against oxidative stress caused by free radicals.

8Fermented Foods (Kimchi, Sauerkraut)
Kimchi in a bowl
Sauerkraut contains live probiotics, beneficial bacteria with far-reaching effects on health including skin health. A Korean study found that 12 weeks of supplementation with probiotics boosted skin elasticity and hydration and reduced wrinkle depth (10). There is also preliminary evidence that probiotics can help reduce stress, which certainly shows on the face. Fermented foods such as sauerkraut (fermented cabbage), kimchi (fermented vegetables with spices), and kombucha (fermented tea) are some of the healthiest sources of probiotics.

9Chocolate
Thin dark chocolate squares
Chocolate (Cacao) - yes it really is true, chocolate is good for you and your skin! A 2015 study found that supplementation with cocoa had positive effects on skin elasticity and wrinkle reduction in women aged 43-86 (11). Other studies have demonstrated reductions in UVB-induced wrinkle formation and collagen degradation following consumption of cacao powder, with evidence indicating that cocoa may alter the expression of genes linked to skin wrinkling (12). This is not surprising, as raw cacao is one of the richest sources of antioxidants of all foods, being particularly high in a type of antioxidant called flavanols.
Nutrition Facts for Dark Chocolate (70-85% Cocoa).
10Watermelon
Watermelon
Watermelon - this juicy, tasty fruit is a top source of lycopene. Lycopene is an antioxidant linked with many health benefits including protecting the skin against free radical damage and UV damage, which are two top causes of skin aging (13). Its high water content (92% water) also makes it a great hydrator, especially in hot weather or post-exercise. In addition, watermelon is a good source of vitamins A and C.

11Spirulina
A spoon of Spirulina
Spirulina is a blue-green algae, sometimes referred to as a "complete food" as it provides all the essential nutrients our bodies need including protein, essential fats, vitamins, minerals, and antioxidants. Spirulina contains a type of essential fat called GLA, which has anti-inflammatory effects and may help calm inflammatory skin conditions. There is also some evidence that spirulina can stimulate the cells in the body that produce collagen, called fibroblasts (14). Other skin-feeding nutrients it provides include vitamins A, C, and E.
Nutrition Facts for Spirulina.
12Seeds
Flax Seeds
Seeds provide vitamin B3 (Niacin), an essential vitamin needed for keeping skin healthy. This water-soluble vitamin helps the epidermis (upper layer) of the skin retain moisture. This helps skin appear smoother with less dryness and can even reduce the appearance of wrinkles. Niacin is also used topically as a treatment for acne. (15) Seeds are also a great source of zinc, needed for healing and repair in the body, including skin healing, healing of blemishes, and preventing scar formation. Clinical trials have shown that zinc supplements can also reduce the severity of acne (16).

More Tips for Maintaining Healthy Skin

  • Exercise increases circulation, improving blood flow and nutrient and oxygen delivery to the skin. The health of your skin is completely dependent on the nutrients it receives this way. (17)
  • Reduce stress and get a good night's sleep - stress increases collagen breakdown in the body and sleep is when your skin regenerates and repairs itself. Women who sleep less than 5 hours have more fine lines, poorer skin elasticity, and skin that takes longer to recover from environmental stressors, according to one study. (18)
  • Limit sun exposure - a tan may give you a healthy glow in the short-term, but UV rays break down collagen and hyaluronic acid in the skin and cause premature aging in the long run. (19)
  • Refined sugar is one of the most damaging foods for your skin. When sugar reacts with body tissues, including collagen and elastin, it leads to the formation of aptly named AGEs (advanced glycation end-products). These cause cells to become stiff, losing their elasticity and becoming more prone to damage and premature aging. (20)
