Beautiful, glowing skin starts with what you eat. Learn how foods and beverages can help you stay young. And discover 10 foods for healthy skin that will give you the antioxidants and other nutrients your skin needs to stay radiant and youthful.
The benefits of healthy eating — such as lowered risk of heart disease, obesity, type-2 diabetes, and certain cancers — are well known.
But did you know that eating right is essential for healthy skin?
How Food Can Keep You Looking Young — Or Age You Prematurely
Food delivers nutrients to your body. Some of these nutrients protect your skin cells from the sun’s rays, some keep your skin hydrated, and some limit skin damage from harmful molecules known as free radicals.
Other nutrients increase cell turnover to reveal healthier skin underneath. And still others build strong cell walls for smooth, firm, supple-looking skin.
On the other hand, fast and ultra-processed foods, such as frozen entrees, soda, French fries, processed meats, and most commercial baked goods, are less nutrient-dense and typically high in salt, sugar, unhealthy fats, and artificial additives.
Processed, refined, and manufactured foods and snacks add to inflammation in your body, and also fuel inflammation on your skin. Skin inflammation can cause redness, acne, and a breakdown of structure that leads to sagging.
Processed foods can also spike your blood sugar, fueling acne and wrinkles through a process called glycation, which also causes the formation of free radicals.
Free Radicals and Your Skin
Free radicals are molecules that have an odd number of electrons on their outer layer. A free radical has a negative charge and wants to have a balanced charge, so it steals an electron from a balanced atom, making another free radical.
Free radical damage (also known as oxidative stress) occurs when there is more free radical creation than there is antioxidant activity in your body.
Free radicals are a key driver of the aging process. They can contribute to cancer, Alzheimer’s disease, and many other forms of chronic illness. They can also damage skin by grabbing electrons from atoms in the skin.
Two of the most visible effects of free radicals are wrinkles and the breakdown of collagen (which in turn causes saggy-looking skin).
While aging and wrinkling are a natural part of life, it’s possible to slow down the process by limiting your exposure to unnecessary free radicals and through a diet rich in antioxidants.
You can avoid free radicals by steering clear of processed foods and limiting your exposure to cigarette smoke, alcohol, environmental pollutants, and industrial chemicals or solvents — including pesticides, herbicides, and toxic household cleaners.
How Antioxidants Fight Free Radicals
Antioxidants create a buffer between your body and the dangerous free radical. They lend electrons to free radicals, so they don’t damage other cells.
Antioxidants also help revitalize your natural ability to heal yourself and remove oxidized cells that aren’t useful to your body anymore.
Where to Get Antioxidants
Natural antioxidants are just as readily available as free radicals.
Every organ works to combat oxidation in its own way, so you need a lot of different antioxidants to get the job done.
You create them naturally within your cells, and you get them in your diet.
You might think, “If I’m making antioxidants to fight the free radicals, why does it matter how much I eat?” Simply put, your body doesn’t make some of the best antioxidants, such as vitamin C, which you need to get from food.
Plus, many of us are facing more pollution, eating more processed foods, using products with more chemical ingredients, and are exposed to more environmental stressors than ever before.
Without mindful input to support your body’s functions, you may face significant oxidative stress, which can fuel illness and premature aging.
Getting optimal vitamin and mineral intake from a balanced diet that’s rich in antioxidant properties is a fabulous way to support not only feeling great but also looking great, too.10 of The Best Antioxidant-Rich, Anti-Aging Foods for Healthy Skin
Here are some of the best foods for healthy skin:
1 — Blueberries
Blueberries are on almost everyone’s list of superfoods — and for good reason. They’re among the most antioxidant-rich foods on earth.
Blueberries’ relatively mild flavor means they’re as adaptable as they are good for you: enjoy with breakfast, afternoon smoothies, dinner salads, or eat them straight as a delicious snack.
If you want to switch it up, strawberries, raspberries, and blackberries — all berries, really — are excellent, nutritious food choices. And they taste pretty good, too!
2 — Oranges
Oranges are packed with water (which helps keep your skin hydrated) and vitamin C.
Your body needs vitamin C to produce collagen, a protein that keeps skin firm and fights the appearance of aging.
A single medium orange has more than 100% of the daily recommended intake of vitamin C!
3 — Pomegranates
Pomegranates are another excellent source of vitamin C, as well as other antioxidants that fight free radicals and promote healthy skin tone.
(Note to dog owners: pomegranates can make some dogs quite ill, so be extra careful.)
4 — Tomatoes
In addition to being an excellent source of the all-important vitamin C, tomatoes are a rich source of the potent phytochemical, lycopene.
Lycopene is an important antioxidant that protects skin from sun damage (by eliminating free radicals caused by ultraviolet rays) and promotes circulatory health. It’s also been found to help fight cancer.
5 — Watermelon
These juicy summer fruits are 90% water, which helps your skin stay hydrated.
Watermelons are also packed with lycopene, so consuming them can help protect your skin from aging, wrinkles, and skin cancer.
In fact, an average watermelon has about 40% more lycopene than raw tomatoes.
6 — Avocadoes
You’ve probably heard that avocados are abundant in the healthy (monounsaturated) fats that help develop and maintain healthy cells and also lower the risk of heart disease and stroke.
Avocados also contain:
- The antioxidants vitamins A and E, which guard against UV rays and keep skin moisturized
- Glutathione, a powerful antioxidant, and
- NMN, a compound that may have anti-aging effects
7 — Kale
It’s about time for a leafy green on this list. Kale is high in potassium, which keeps skin cells hydrated and firm.
It also has the antioxidant vitamin K, which helps with blood clotting and may help with spider veins, scars, and circles under the eyes.
8 — Sweet Potatoes
That sweet potatoes are both better tasting and better for you than russets is one of nature’s more delicious twofers.
Sweet potatoes are rich in vitamin C and beta-carotene, which your body converts into vitamin A and antioxidants.
9 — Wild Salmon
There are many ethical and sustainability reasons why some people choose to avoid salmon and other fish products.
If you do choose to eat fish, wild salmon can be an excellent low-mercury source of omega-3 fats, which can keep skin moisturized, reduce inflammation, and may even guard against skin cancer.
10 — Green Tea
Hydration is essential for healthy skin. And green tea is among the best ways to stay hydrated.
It contains antioxidants, vitamin B3, and a chemical (EGCG) that helps skin cells stay healthy.
Green tea also contains caffeine — about a quarter as much as coffee — so if you’re caffeine-sensitive you may want to limit your intake.
The Takeaway
You’ve probably detected a theme here. Fresh fruits and vegetables are where it’s at, especially ones that are high in antioxidants.
Staying hydrated and enjoying an abundance of diverse antioxidant-rich foods can provide a lifetime of benefits for you — and for your skin.
And of course, food is only part of your overall wellness picture. A nice, brisk walk (yes, even in winter!) helps to maintain cardiovascular and mental health. And sunlight can stimulate your body to produce the extraordinarily health-promoting vitamin D.
