Spices are a rich source of polyphenols, which means we should all be eating more of them. Polyphenols are powerful anti-oxidants that neutralize the free radicals formed by constant sun exposure and anti-microbial agents that are plants’ primary defense mechanism against microbiological attack. By ingesting foods that contain high levels of polyphenols, humans boost their immune systems, reduce cellular inflammation, and maintain an optimal balance between the good and bad microbes that live in our digestive tracts.
Adding more spices to your diet is one way to increase the number of polyphenols entering your body on a regular basis, although, as Dr. Barry Sears explains in The Mediterranean Zone, you need to have continual daily intake in order to benefit in the long term, since polyphenols are fully metabolized within 24 hours of being taken into the body.
