41. Green Banana Flour – The Resistant Starch Champion

Made from unripe green bananas, this flour is one of the richest natural sources of resistant starch—a unique type of fiber that feeds gut bacteria, balances blood sugar, and supports weight management. Green banana flour is also high in potassium and magnesium. It’s neutral in taste and can be used in smoothies, pancakes, or as a gluten-free flour alternative. Its gut health benefits make it a stealthy and versatile superfood worth adding to your rotation.

42. Avocado Leaves – The Anti-Inflammatory Herbal Secret

Most people love avocados, but the leaves are where the real magic lies. Used traditionally in Mexican herbal medicine, avocado leaves contain quercetin, polyphenols, and flavonoids that reduce inflammation, regulate blood sugar, and fight oxidative stress. Often steeped as tea or used to flavor beans and stews, the leaves offer a unique herbal addition with serious health benefits that go far beyond the fruit’s creamy flesh—and way beyond what kale offers.
