Does Avoiding Seed Oils Stop Sunburns? Stories vs Research
Does cutting out seed oils help you look better and even burn less in the sun? This is one of the most shared wellness ideas right now. Seed oils are oils like canola, soybean, sunflower, corn, and safflower. Some creators call them "toxic" and swap them for butter, olive oil, or beef tallow. Here is a fair look at the claims.
What supporters say online
Many people online say that after they cut seed oils:
- Their skin looked clearer and less red
- They felt less bloated and puffy
- They burned less in the sun, or could stay out longer without sunscreen
The sunburn idea goes like this. Seed oils are high in a fat called linoleic acid. Supporters say this fat gets stored in the skin, breaks down in the sun, and causes more damage and burning. So, they say, if you avoid seed oils, your skin can handle more sun.
Why personal stories can mislead
These stories are real experiences, but they are not proof. People who cut seed oils usually cut fried food, chips, and fast food too. They may also be paying more attention to their health in general. Sunburn also changes a lot based on the season, time of day, cloud cover, and where you live. Someone who says they burned less this summer may have just had different weather or spent less time in strong sun.
What research says
Food Facts, a science based fact check group, found that the seed oil and sunburn idea comes from some animal studies and theories, but no strong human studies show that eating seed oils makes you burn more. There are no good trials showing that avoiding them protects you from the sun.
A dermatologist at OHSU told Business Insider that online claims saying you can skip sunscreen if you eat the right foods are false.
For seed oils in general, Harvard experts say they are not harmful on their own. Studies link the main fat in them to a lower risk of heart disease. The bigger concern is eating lots of fried and highly processed foods, which often contain these oils.
Some people also put oils on their skin as natural sunscreen. A study testing 14 plant oils found most gave almost no sun protection.
Positives
- Less junk food. Cutting seed oils often means fewer fried and processed foods, which is a good change.
- More cooking at home. That usually helps your diet.
Negatives
- False sense of safety in the sun. This is the biggest risk. Skipping sunscreen can lead to burns, early wrinkles, dark spots, and skin cancer.
- Swapping for more saturated fat. Using lots of butter or tallow may not be better for your heart.
- Food fear. Seeing one type of oil as poison can make eating stressful.
What protects your skin
- Use a broad spectrum sunscreen with SPF 30 or higher
- Wear hats and sun protective clothing
- Seek shade when the sun is strong
- Eat plenty of fruits and vegetables
Bottom line
Personal stories about seed oils and sunburn are interesting, but research does not back them up. Avoiding seed oils will not replace sunscreen. A healthy, sun safe glow shows up in photos, and The Face They See lets people of the opposite gender rank your photos for free.
