Leafy Greens (Spinach, Kale, Swiss Chard)

Dark leafy greens provide concentrated vitamin K, which directly inhibits pro-inflammatory cytokines, along with polyphenols and carotenoids that neutralize free radicals. A Tufts University study found participants consuming 1+ servings of leafy greens daily showed cognitive decline rates equivalent to being 11 years younger, attributed partly to reduced neuroinflammation.
