2. Microbiome Diversity and Its Impact on Skin Health

A diverse gut microbiome is crucial for healthy, glowing skin. People who eat a wide variety of fruits, vegetables, and high-fiber foods tend to have richer gut flora—and, studies suggest, fewer skin problems. Compared to diets high in processed foods and sugars, which can throw gut bacteria out of balance, fiber-rich foods help nourish beneficial microbes that support anti-inflammatory responses. Research shows that this microbial diversity can strengthen the skin’s barrier and reduce sensitivity.
