Peanuts and herbs and spices may positively impact gut microbiome

The human gut microbiome is a collection of trillions of microorganisms that live inside the intestinal tract which can affect nearly all systems of the body, including metabolism and the building and maintaining of the immune system.
Researchers have found in a new research from Penn State that Peanuts and herbs and spices may positively impact gut microbiome. Adding a daily ounce of peanuts or about a teaspoon of herbs and spices to your diet may affect the composition of gut bacteria, an indicator of overall health. In two separate studies, nutritional scientists studied the effects of small changes to the average American diet and found improvements to the gut microbiome.
"Research has shown that people who have a lot of different microbes have better health, and a better diet, than those who don't have much bacterial diversity," said Penny M. Kris-Etherton, Evan Pugh University Professor of Nutritional Sciences, Penn State.
For the peanut study, which published in the journal Clinical Nutrition, Kris-Etherton and her colleagues compared the effects of snacking on 28 grams (approx. 1 ounce) of peanuts per day, versus a higher carbohydrate snack-crackers and cheese. At the end of six weeks, participants who ate the peanut snack showed an increased abundance of Ruminococcaceae, a group of bacteria linked to healthy liver metabolism and immune function.
