Recent research led by Dr. Li Jiao at Baylor College of Medicine has provided new insights into how different dairy products affect the gut microbiome. The study suggests that milk consumption enhances gut biodiversity by promoting beneficial bacteria, whereas cheese consumption may reduce certain microbes important for intestinal balance.
Milk and Gut Biodiversity
Milk intake was associated with increased levels of beneficial bacteria such as Faecalibacterium and Akkermansia. Faecalibacterium is known for its anti-inflammatory properties and role in maintaining gut balance, while Akkermansia is linked to healthy weight management and blood sugar control. These bacteria contribute to a more adaptable and resilient gut environment .
Cheese and Microbial Reduction
In contrast, higher cheese consumption was linked to a decrease in certain gut microbes, notably Bacteroides and Subdoligranulum. These bacteria are involved in colon health and metabolic functions. The reduction of these microbes suggests that cheese may alter the gut microbiome in ways that could affect intestinal balance .
Considerations
It’s important to note that the study had limitations, including a small sample size of 34 older men, which may affect the generalizability of the findings. Additionally, self-reported dietary intake can introduce inaccuracies. Therefore, while the results are promising, further research with larger and more diverse populations is needed to fully understand the relationship between dairy consumption and gut health .
For individuals considering dietary choices to support gut health, incorporating milk may be beneficial due to its positive association with gut biodiversity. However, moderation in cheese consumption might be advisable until more comprehensive studies are available.
