9. Add Lean Protein to Your Plate
Eat a balanced diet that includes an adequate amount of protein. “High-protein foods contain amino acids that are critical for collagen synthesis,” says Garshick. Lean protein sources include fish, seafood, skinless chicken breast, and lean cuts of beef and pork.
10. Limit Your Added Sugar Intake
A diet rich in sugar promotes the formation of advanced glycation end products (aptly called AGEs) that break down collagen, says Chwalek. Limit sugar consumption by reading the back of food labels and looking at either the “added sugar” line in the nutrition label or reading the ingredient list.
