Summary
Can what you eat really change your skin?
Dr. Jessica Krant, board-certified dermatologist and lifestyle medicine physician in New York City, joins Chuck Carroll at the International Conference on Nutrition and Medicine to explain the powerful connection between diet, inflammation, and skin health.
From acne and rosacea to wrinkles and premature aging, Dr. Krant breaks down how dairy, sugar, ultra-processed foods, and stress impact the skin — and how whole plant foods can help reverse damage and support collagen naturally.
You'll learn about the gut-brain-skin axis, advanced glycation end products (AGEs), collagen supplements, beauty sleep, and why stress might be triggering your breakouts.
