A diet rich in walnuts increases beneficial gut-bacteria, and improves brain health, studies show
Walnuts have already earned a reputation as a so-called “superfood” due to the fact that they contain high amounts of fiber, fatty acid (omega 3), and alpha-linolenic acid.
Recent studies have revealed that adding the nuts to your diet have even more benefits than originally suspected: consumption of walnuts has been linked to lower risk of cardiovascular disease, slowed the growth of tumors in animals, and improvements in brain health overall.
Researchers state that walnuts alter bacteria in the gut after conducting a study in which one group of rodents was put on a diet including walnuts and another group followed a diet without walnuts.
The researchers then proceeded to measure the bacteria in the rodents’ guts and descending colons, then proceeded to compare the results.
The researchers discovered two different types of bacterial communities in the groups, with the group on the “walnut-diet” showing considerable increases of beneficial bacteria, and general positively diverse bacteria.
Beneficial bacteria reduces risk of obesity and symptoms of chronic illnesses such as IBS
The lack of bacteria in the gut has typically been associated with an increased risk of obesity, and an aggravation of symptoms in diseases such as Crohn’s and IBS.
Diverse, functional bacteria have conversely been proven to have positive effects on the health of the gut overall, and general health benefits.
The study proves that consuming walnuts enables bacteria of a probiotic-type to increase in the gut and generally contribute to better health.
Probiotic supplements are taken by individuals hoping to improve their gut health in general to people aiming to lose weight, as they decrease and promote activity and numbers of certain types of bacteria: walnuts contain probiotics naturally in abundance.
