You’ve probably heard about “free radicals,” the rogue cell-damaging molecules produced by your body’s daily metabolic activity and environmental toxins.
Polyphenols stimulate the body to defend against free radicals, so getting lots and lots of plant polyphenol antioxidants is important. Preferably polyphenols from dark blue, red, purple and green fruits and vegetables that:
Support healthy inflammation and immune response (and even support blood flow to the brain) by maintaining the balance of cellular antioxidant action and cytokines in your bloodstream
Protect your gut by supporting the amount of healthy bacteria (Bonus: your gut bacteria are responsible for metabolizing polyphenols, so the better your gut bacteria, the better your body can use all the antioxidants you get from them)
Help grow and protect new brain cells by supporting your levels of brain-derived neurotrophic factor (BDNF) and brain nerve growth factor (NGF) — vital proteins that encourage "neurogenesis" (the normal and on-going process of growing brand-new neurons) and protect new brain cells from dying off
Plays a crucial role in the signals that trigger removal of old cells so that the body can bring in new healthy cells
