Eating too much sugar and fatty junk food can make your skin age faster because these foods trigger chemical reactions that damage skin cells and make them lose their bounce and glow.

Eating too much sugar and white bread can cause gummy sticky stuff to form in your skin, which makes your collagen and elastin fibers stick together—leading to stiff, wrinkly skin that doesn’t bounce back like it used to.

Eating more fruits, veggies, and whole foods while cutting back on sugar and white bread can help keep your skin from getting damaged by sticky sugar molecules that make it age faster.

Eating foods rich in antioxidants like berries, nuts, and leafy greens might help keep your skin looking younger by protecting the proteins that make it firm and bouncy, and by reducing damage from everyday environmental stress.

When sugar in your body sticks to skin proteins without needing enzymes, it creates gunk that makes skin wrinkle and lose elasticity — and scientists have studied this process more than almost any other cause of aging skin.
