Summary

Story at-a-glance

People with the highest consumption of ultraprocessed foods had a 23% higher risk of developing psoriasis compared to those who ate the least, based on a 12-year study of 121,019 participants
Replacing just 5% of UPFs with unprocessed foods lowered psoriasis risk by 14%, and replacing 20% dropped it by 18%, making this a powerful prevention strategy
Seed oils and additives in UPFs fuel chronic inflammation and increase body mass index (BMI) — two factors that significantly raise your chances of developing autoimmune skin disorders like psoriasis
If you’re genetically at risk for psoriasis, eating a high-UPF diet increases your likelihood of developing the condition by 2.7 times compared to those with low genetic risk and low UPF intake
Reducing seed oil intake and restoring vitamin D levels through safe sun exposure or supplementation helps repair immune function and strengthens your skin’s natural defenses

0:22.6	Hello, and welcome to Dr. Mercola's cellular wisdom. I'm Ethan Foster, and together
0:29.7	with co-host Alara Sky, we're unpacking how everyday convenience foods quietly reshape your
0:35.0	skin's future. Thanks, Ethan. Soriasis isn't merely a cosmetic irritation.
0:40.7	It's an autoimmune condition that speeds up how quickly your skin cells turn over,
0:45.7	leaving red, itchy, scaly plaques that can erode comfort and confidence. About 3% of the global
0:51.9	population lives with it, yet nutrition's influence usually stays under the radar.
0:56.8	That changed with a 12-year analysis of more than 121,000 UK adults.
1:03.0	Researchers excluded anyone who already had psoriasis, then group participants into four quartiles
1:08.9	based on how much ultra-processed food, packaged
1:12.2	snacks, sugary drinks, ready to eat meals, they consumed.
1:17.0	Compared with the lowest eaters, the top group faced a 23% higher incidence of psoriasis.
1:23.1	The gradient was striking.
1:24.9	Risk climbed 7% in the second quartile, 19% in the third, then 23% at the peak.
1:31.4	Every additional 10% of calories from ultra-processed foods bumped risk another 6%. That linear rise
1:38.5	shows dose matters. You don't need extreme junk intake to push inflammation beyond tolerance.
1:43.8	Encouragingly, dialing back ultra-processed intake pays off fast.
1:48.5	Swapping just 5% of those items for whole foods.
