Almonds can help support the gut microbiome

The research involved three groups replacing their regular snacks with whole almonds, ground almonds, or an energy-equivalent control muffin.The authors conclude that incorporating almonds into the diet could be a way of increasing fiber intake without triggering gut symptoms.We are still learning about the human microbiome, the 10–100 trillion microorganisms living in our bodies, primarily in the human gut. Piece by piece, researchers are putting together how this vast and tiny universe operates, and how it influences our health.An important player in gut health appears to be butyrate, a short-chain fatty acid that supports the health of the microbiome itself.“In addition,” said Dr. Creedon, “butyrate produced in the gut can enter the bloodstream where it is involved in the regulation of health in other areas of the body, such as the liver, brain, and lungs.”Dr. Creedon is a postdoctoral researcher in the Department of Nutritional Studies at King’s College London. She is also the first author of a new study exploring the value of almonds as a means of supporting the microbiome’s supply of butyrate.The study demonstrates that eating a healthy handful of almonds each day promotes the production of butyrate.The importance of butyrateDr. Creedon’s research documents the benefits of eating about 56 grams, or 2 ounces, of almonds daily — that amounts to about 46 almonds.“Butyrate supports the gut barrier, which keeps bacteria and other microbes from entering your blood. In doing so, butyrate can help to reduce inflammation, manage conditions like IBS [irritable bowel syndrome], and decrease gastrointestinal discomfort like bloating,” Allison Tallman, a registered dietitian nutritionist, told MNT.“Butyrate is produced through the fermentation of fiber in the colon. Therefore, increasing fiber in the diet, such as in almonds, increases butyrate levels, which has a positive effect on our gut health,” said Tallman.One group ate two portions of 28 grams of whole almonds each per day, while another group had two portions of 28 grams of ground almonds daily. The final control group ate muffins that delivered an equivalent amount of energy to the body as the almonds. The trial period was 4 weeks.At the end of the trial, researchers found that the almond groups had significantly higher levels of butyrate in their fecal matter than did the control group, 24.1 micromoles per gram rather than 18.2 micromoles per gram.There was no significant difference between groups in gut symptoms, gut transit time — the amount of time it takes for food to enter and exit the digestive system — or stool consistency.In addition, all three groups had a similar abundance of fecal bifidobacterial with no evident differences in gut microbiota at the phylum level or in terms of diversity.Whole almonds vs. ground almondsThe study tracked the difference between eating whole or ground almonds in terms of butyrate production.Individuals who ate whole almonds had 1.5 more bowel movements each week than those who ate ground almonds.Dr. Creedon speculated on why this may be the case: “Whole almonds differ from ground almonds in the amount of fat that reaches the colon. When we consume whole almonds, much of the fat escapes digestion and reaches the colon. In comparison, more of the fat in ground almonds is digested in the upper [gastrointestinal] tract.”“It is possible,” Dr. Creedon noted, “that the increased fat in the colon of whole almond eaters served to increase ease of passage of the stool, and increase stool weight. Both of these effects might increase stool frequency in these people. There is little research on the impact of fat on stool frequency. Therefore, these findings require further investigation in future trials.”Surprisingly, said Dr. Creedon, “[f]ollowing chewing, ground almonds had significantly smaller sized particles in comparison to chewed whole almonds.”“When we inserted the measured values of these particle size distributions of whole and ground almonds into a mathematical model that predicts the amount of fat released from chewed almonds during digestion, we found that the model predicted that ground almonds released significantly more fat than whole almonds,” she added. – Sciencedaily.comSTATSFoods For Good Gut HealthYoghurtKefirMisoSauerkrautKimchiSourdoughDid you know?Size matterThe gut makes up roughly 70% of your immune system and contains 1.5kg to 2kg of bacteria – more than the weight of your brain.Health tipIncorporate stress-management strategies daily.Health precaution tipReduce your exposure to environmental toxins.See a doctor when you experience symptoms like excess gas or abdominal pain.
