What your gut remembers

Tiger nut isn't a nut. It's a small, sweet tuber that humans have eaten for at least 6,000 years — older than most grains in the modern diet.

Its quiet superpower is resistant starch: a form of carbohydrate that feeds the bacteria of the lower gut rather than spiking blood sugar. The result is slow energy, steadier moods, and a microbiome that has something interesting to work with.
