Uncommon Superfoods for a Happier, Healthier Gut

33. Barley – The Under-the-Radar Gut Grain

Barley is rich in beta-glucan, a type of soluble fiber that feeds the microbiome and supports immune health. It helps maintain healthy cholesterol levels while regulating digestion and keeping you full. Its chewy texture makes it perfect for hearty soups, grain bowls, or as a rice alternative that doubles as a gut-boosting staple.

34. Green Bananas – A Resistant Starch Goldmine

Before they ripen and sweeten, green bananas are one of the richest sources of resistant starch—a prebiotic that supports good bacteria growth, reduces gut inflammation, and improves insulin sensitivity. Blend them into smoothies, cook them like plantains, or find them in green banana flour for baking. They're particularly helpful for people healing from leaky gut or balancing blood sugar.
