Common Search Questions
Can food really change your skin color?
Yes. Carotenoids from certain fruits, vegetables, and animal products can accumulate in the skin and create a subtle yellowish or reddish tint.
Is carotenoid skin color the same as tanning?
No. Tanning comes from melanin changes after UV exposure, while carotenoid coloration comes from dietary pigments deposited in skin.
Which foods contain carotenoids?
The transcript mentions carrots for alpha- and beta-carotene, tomatoes for lycopene, and animal products such as egg yolks and salmon.
Can carotenoids protect against UV damage?
The caption says carotenoids in the skin can help protect against UV damage, though they should not be treated as a replacement for sunscreen.
Key Takeaways
- “Eating too many carrots can turn you orange” is directionally true, but a moderate carotenoid glow can be desirable.
- Carotenoid coloration may be rated as more attractive than equivalent melanin-based tanning in the studies discussed.
- The color balance matters; too much orange can look unnatural.
- Food choice and preparation can strongly affect how much carotenoid your body can access.

Dietary color and skin tone
Here’s some science I wish I knew before I was in my 30s. You can change your skin color by eating the right fruits and veggies, and multiple studies have shown that this change is consistently rated as more attractive than an equivalent suntan, if you don’t overdo it.
So there are some tricks for getting it right.
Welcome back to 30 Studies to Change Your Life: Nutrition Week continued.
What carotenoids are
Turns out that humans are wired to find the glow from a nutritious diet attractive, sort of like how peacocks flaunt their colors. Enter carotenoids.
The colorful superheroes of the fruits and veggie world are also found in some animal products like egg yolks and salmon. They’re not just potential cancer and heart disease fighters; they also work wonders on your skin tone.
From the orangey alpha- and beta-carotene that you find in carrots to the lycopene that you find in tomatoes.
How carotenoids reach skin
When you eat fruits and veggies, these carotenoids make their way out through your sweat glands and then back into the outer layer of your skin, making it look a bit more yellowish or reddish, sort of like a natural bronzer and blush.
What the studies compared
These studies had people rate the attractiveness of the color change from either carotenoids or suntanning in both Caucasian and Black faces.
People rated the carotenoid coloring as more attractive, which was a surprise to me. Then they showed that supplementing for just eight weeks was enough to make a meaningful change.
Food versus supplements
But I prefer foods to supplements, and which ones you choose and how you prepare them can make more than a 10x difference in the available carotenoids that you can consume.
So next time we’ll cover the best foods and preparation methods and a fun experiment that I’ll be starting. So many sunburns that younger me should have avoided.
Additional Notes
Caption context
The caption adds that carotenoids in skin can help protect against UV damage, that carotenoids may also reach skin through slower diffusion from adipose tissue, blood, and lymph, and that the yellow-red balance matters.
Study interpretation notes
The caption says three studies found people preferred the yellowish look of carotenoids over melanin-like color changes using computer-adjusted face-color sliders. It also notes limitations around capturing a specific tanned look and representing Black faces.
