Spice Up Health: Everyday Seasonings Linked to Gut, Brain, and Metabolic Benefits

A UCLA-led Nutrition Reviews analysis suggests common kitchen spices may influence glucose regulation, inflammation, brain function, and the gut microbiome. Cinnamon may reduce postprandial insulin and glucose and shift gut bacteria; capsaicin from peppers and nonpungent DCT may boost thermogenesis; turmeric’s curcumin potentially improves memory and cholesterol and works with black pepper; spice mixes rich in polyphenols support beneficial gut microbes and lower oxidative stress. However, real-world dosing, cooking methods, and bioavailability vary, and more robust human trials are needed.
