You can’t eat your sunscreen. But what you eat can help against sun damage.

Everyone knows to slather on the sunscreen to block the sun’s UV rays, but there’s one crucial step your sun-protection routine might be missing: Breakfast!

 Diet is often overlooked as a part of how we adapt to our external environments throughout the seasons. Let’s take a look  at why the first meal of the day can protect your healthy summer glow.

Why eating these ingredients in the daytime is important

Turns out we have a “skin clock,” says Joseph S. Takahashi, PhD, chairman of neuroscience at the University of Texas. Takahashi and his team found that an enzyme that repairs UV-damaged skin has a daily cycle of production that can be altered by eating food at unusual times.

It is likely that if you have a normal eating schedule, then you will be better protected from UV during the daytime. If you have an abnormal eating schedule, that could cause a harmful shift in your skin clock.

So rather than a midnight snack, try incorporating these skin-loving foods into your smoothies to add a little extra sun protection into your diet:

1- Blueberries

It just so happens that our favorite summer fruits are also the ones that help protect us during summer, too. Blueberries are rich in powerful antioxidants that fight off free radicals that can damage skin due to sun exposure and stress. They’re also a very good source of vitamin C, which can help prevent wrinkles.

Tomatoes are known for containing lycopene, an antioxidant responsible for tomatoes’ red color. But watermelons actually contain far more. Lycopene absorbs both UVA and UVB radiation, although it may take several weeks for the skin to become more photoprotective due to its turnover rate. After a few weeks of daily, juicy watermelon consumption, lycopene can eventually act as a natural sunblock. Researchers note, though, that it doesn’t necessarily take the place of other protective measures, like SPF and sun-protective clothing, against sunspots and skin damage. But when it comes to anti-aging, this extra boost sure won’t hurt.

3- Nuts and Seeds

Walnuts, hemp seeds, chia seeds, and flax all contain omega-3 essential fatty acids. Fish and eggs are also great sources of this clean, skin-loving fat. Our bodies can’t make omega-3s, so it’s essential that we get them from our diet.

What do omega-3s do for your skin? They help maintain your skin’s integrity and are anti-inflammatory, too. Omega-3s also help your body naturally cope with the effects of spending a little too much time in the sun.

4- Carrots and Leafy Greens

Our bodies convert beta carotene into vitamin A, which is vital for skin health. A 2007 meta-analysis found that beta carotene provided natural sun protection after 10 weeks of regular supplementation.

Eating a variety of foods rich in this nutrient makes getting the daily quota a little easier. Carrots and leafy greens like kale and spinach are great beta carotene-packed additions to your meals, even breakfast smoothies. In particular, leafy greens are high in the antioxidants lutein and zeaxanthin. These help protect against wrinkling, sun damage, and even skin cancer.

5- Green Tea

Glass cups with green tea and tea leaves isolated on white.

A study on green tea found that it reduced skin damage from UVA light and protected against the decrease of collagen. Collagen is our body’s most abundant protein. It gives skin its integrity and firmness.

6- Cauliflower

When it comes to veggies and fruits, a general health rule to live by is to gravitate toward more vibrantly colored ones. This is because they’re likely to have more antioxidants. But don’t let cauliflower’s florets fool you. This cruciferous veggie is the exception to the rule. Cauliflower contains potent antioxidants that help fight off oxidative stress from free radicals.

On top of this perk, cauliflower is also a naturally sun-protective food thanks to histidine. This alpha-amino acid stimulates the production of urocanic acid, which absorbs UV radiation.

Super Summer Sunblock Smoothie

Who says you can’t drink your sun shield? This smoothie helps you beat the heat and contains all of the skin-protective ingredients listed above. Add it to your morning rotation for a healthier glow all summer long.


  • 1 1/2 cup green tea, cooled

  • 1/2 cup cauliflower
  • 1 small carrot

  • 3-5 ice cubes

While these nutrient-rich, whole foods may support the health of your skin when exposed to UV light, keep in mind that they’re not a substitute for sunscreen. Still apply sunscreen every day to prevent sun damage and skin cancer. Think of these foods as a little extra insurance if you happen to over-soak the sun’s rays.

Happy sunning!!
