Kale

Kale delivers 684% of the daily value for vitamin K per cup and 134% for vitamin A, ranking it higher than the average leafy green in nutrient density. Its glucosinolates have been shown to reduce cancer cell growth by 40% in laboratory studies, a concrete advantage over #4 Turmeric, which requires piperine for comparable absorption. Kale also provides 120mg of calcium per serving, surpassing most vegetables in mineral content for bone health.
