What is Fried & High-Heat Cooked Foods?

Oxidized fats and AGEs generated at high temperatures accelerate skin aging

Peroxides and aldehydes from reused cooking oils damage cells and accelerate collagen breakdown.

Main causes & characteristics of Fried & High-Heat Cooked Foods

When oil is repeatedly heated at high temperatures, fats are known to oxidize, generating irritants such as peroxides and aldehydes. It has also been reported that advanced glycation end-products (AGEs), formed when proteins and sugars bind during high-heat cooking, may accelerate the breakdown of skin collagen and promote loss of elasticity.

Managing Fried & High-Heat Cooked Foods

It is advisable to reduce the frequency of fried foods and switch to lower-heat cooking methods such as grilling, steaming, or boiling. When consumption is unavoidable, using fresh oil and pairing fried dishes with antioxidant-rich vegetables and fruits may help manage oxidative stress. If skin concerns persist despite dietary adjustments, consulting a dermatologist is recommended.
