Dairy consumption has long been valued for its nutritional benefits, but new research suggests it may also have a profound impact on the gut microbiome. A study led by Dr. Li Jiao from Baylor College of Medicine found that milk intake is associated with an increase in beneficial bacteria, while cheese may reduce certain microbes important for maintaining a balanced intestinal environment.
According to experts, dairy interacts with the microbiome, supporting a broader range of gut microbes and indicating a more adaptable gut. Scientists have explored the role of milk in encouraging the growth of bacteria linked to lower inflammation and improved gut barriers. These beneficial bacteria include Faecalibacterium, known for producing substances that help maintain gut balance, and Akkermansia, which has been linked to healthy weight and blood sugar control.
However, cheese appears to have different effects, reducing Bacteroides and Subdoligranulum, two common gut residents that may influence colon conditions. The study also found that certain dairy habits can increase the presence of Bifidobacterium, a probiotic often associated with improved digestion.
While yogurt was not shown to have a significant impact on gut microbiota changes in this study, researchers plan to explore its effects in future trials. Dietitians emphasize that daily dairy recommendations should be individualized based on factors such as age, lifestyle, and health status, and caution against making broad assumptions about all dairy products.
The study’s findings highlight the need for more personalized dietary advice and suggest that the type of dairy product consumed may play a significant role in shaping gut bacteria balance.
