Nutrients Examines Gut Bacteria Across 265 Adults

Buzzline

The study examined gut bacteria in 265 adults who consumed cow’s milk, plant-based beverages, or neither. Researchers included 99 non-milk consumers, 139 cow’s milk consumers, and 27 plant-based beverage consumers. They found small differences in microbial composition, but those differences were no longer statistically significant after matching participants for characteristics such as age and body composition. Because the study used a cross-sectional design and self-reported consumption, its findings are exploratory and cannot establish cause and effect.

00:00about 1.2% of gut bacterial variation related to group differences between cow's milk and plant

00:12finding in Nutrients, a research journal, after studying 265 adults. They included 139 cow's milk

00:20drinkers, 27 plant beverage drinkers, and 99 who consumed neither. But plant beverage drinkers were

00:27younger, with less body fat than the other groups. So researchers matched participants by age, sex,

00:33and body measures. After matching, differences in bacterial diversity and individual bacterial

00:38groups were no longer statistically significant. Yet the matched comparison included only 23 people

00:45per group, with some participant differences remaining. Those limits make the findings

00:50exploratory, not evidence that beverage choice has no effect. And participants reported habits,

00:55rather than precise amounts consumed. The study's design also cannot establish cause and effect.

01:01So beverage choice alone remains unconfirmed as the explanation.
