Whole grains have nourished humans for millennia. These intact grains contain all three parts of the seed— bran, germ, and endosperm
Whole grains pack a powerful gut-health punch. They're rich in fermentable carbs, dietary fibre, and starch
Undigested carbs that reach the colon get broken down by gut microbes into short-chain fatty acids
Short-chain fatty acids like butyrate, acetate, and propionate nourish healthy gut bacteria and protect the intestinal lining
Some popular whole grains include: oats, barley, rye, sorghum, triticale and millets.
The soluble fibres in whole grains help lower cholesterol and improve glucose responses
Studies show whole grains are rich in oligosaccharides that boost gut-friendly bifidobacteria while decreasing problematic E. coli, clostridia, and bacteroides.
