Snacking on almonds boosts gut health

through the production of short-chain fatty acids, such as butyrate. These molecules act as a fuel source for cells in the colon, they regulate absorption of other nutrients in the gut, and help balance the immune system,” Lead author, Professor Kevin Whelan, Head of Department of Nutritional Sciences, said.

Researchers found that butyrate was significantly higher among almond eaters compared to those who consumed the muffin. Butyrate is a short-chain fatty acid that is the main source of fuel for the cells lining the colon. When these cells function effectively, it provides an ideal condition for gut microbes to flourish, for the gut wall to be strong and not leaky or inflamed and for nutrients to be absorbed.

No significant difference was observed in gut transit time – the time it takes for food to move all the way through the gut – however whole-almond eaters had an additional 1.5 bowel movements per week compared to the other groups.

These findings suggest eating almonds could also benefit those with constipation.

Testing showed that eating whole and ground almond improved peoples’ diets, having higher intakes of monosaturated fatty acids, fibre, potassium and other important nutrients compared to the control group.

Professor Whelan added: “We think these findings suggest almond consumption may benefit bacterial metabolism in a way that has the potential to influence human health.”
