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, according to new research from Penn State.

In two separate studies, nutritional scientists studied the effects of small changes to the average American diet and found improvements to the gut microbiome.

The human gut microbiome is a collection of trillions of microorganisms that live inside the intestinal tract. The bacteria there can affect nearly all systems of the body, including metabolism and the building and maintaining of the immune system.
