Coffee Lovers Have Healthier Composition of Bacteria in Guts

A recent study, conducted by a team of researchers from the Baylor College of Medicine in Houston, US, finds that people who regularly drink coffee have healthier compositions of bacteria in the guts.Coffee Lovers Have Healthier Composition of Bacteria in Guts

The study included 34 participants who were asked to undergo a screening colonoscopy and endoscopy to confirm that their colons are healthy. The researchers obtained 97 colonic mucosa biopsies from different segments of the colon, extracted microbial DNA, and performed 16s rRNA sequencing analysis.

The analysis of the received data showed that people who consume lots of caffeine had high levels of “good” bacteria such as Faecalibacterium and Roseburia, and low levels of Erysipelatoclostridium, a potentially harmful bacterial genus.

The authors write in their paper: “Higher caffeine consumption was associated with increased richness and evenness of the mucosa-associated gut microbiota, and higher relative abundance of anti-inflammatory bacteria, such as Faecalibacterium and Roseburia and lower levels of potentially harmful Erysipelatoclostridium.”

Study: Lifetime Exercise Linked to Lower Risk of Colon Polyps

A study, recently published in the British Journal of Cancer, suggests that lifetime exercise is associated with a significantly lower risk of developing colon polyps in senior age.Study Lifetime Exercise Linked to Lower Risk of Colon Polyps

The study includes analysis of data from 28,250 US nurses from the Nurses’ Health Study II which took place from the late 1980s till years 2011. The health information included all illnesses and habits, medicines taken, and other conditions.

The analysis of the data showed that people who were physically active between 12 and 22 were 7% less likely to develop polyps; those who exercised during adulthood, between 23 and 64, had 9% lower risk, and those who were active in both age intervals had 24% lower risk of developing polyps.

One of the study authors Leandro Rezende says: “Whether it’s during adolescence or adulthood, the more physical activity we get, the lower the risk of developing adenoma in adulthood becomes.”
