Milk is a staple food in many households. It has long been appreciated for nutrients such as calcium and vitamin D, but new data alludes to another advantage which involves the complex community of microbes inside the digestive system.
Recent results, led by Dr Li Jiao Since Baylor College of Medicineshows that milk consumption is linked to an increase in several useful bacteria, while cheese can reduce certain significant microbes for a balanced intestinal environment.
How dairy products help the intestine
Experts say that dairy products interact with the microbiome, which is the mixture of microorganisms in the body that help decompose nutrients. Milk seems to support a larger range of intestinal microbes, a sign of a more adaptable intestine.
Scientists explored the role of milk to encourage the growth of bacteria linked to a drop in inflammation and to improve intestinal barriers.
A few researchers Suggest that this trend could be linked to the carbohydrate content in dairy products, but the details remain under survey.
Examine the bacteria keys
Several microbes related to dairy products stand out. One is FaecalibacteriumKnown to produce substances that help maintain intestinal balance and calm inflammation.
Another is Akkermansiaoften mentioned for his link Healthy weight and blood sugar control. Investigators say that these bacteria can be more abundant in the intestine when the consumption of milk increases.
The cheese seems to bring different consequences by reducing the bacteroides, which are current intestinal residents which can influence the conditions of the colon. He also seems to be down SubdoligranulumA genre thought to play a role in metabolic health.
Scientists have noticed that BifidobacteriumConsidered a probiotic, can also increase with certain dairy habits. This possibility has aroused interest among professionals looking for food means to support digestion.
What yogurt has not revealed
Although yogurt is often rented for its probiotic potential, this study has not found clear links between the contribution of yogurt and intestinal microbiota changes.
It is probably because the participants reported a very low yogurt consumption overall, limiting a significant analysis.
Without enough data, the researchers could not determine if the yogurt had the same effects on key bacteria like Akkermansia or Faecalibacterium.
A more diversified and higher contribution of yogurt in future studies may be necessary to explore how fermented dairy products compare to milk and cheese.
Dairy and intestinal health contribution
Some researchers point out that milk has more lactose, which could help raise the presence of healthy bacteria.
The cheese, produced by fermentation, contains less lactose but includes other elements which could shape the intestine in a different way.
Dietitists remind people that daily dairy recommendations may differ depending on age, lifestyle and health. People sensitive to lactose or subject to certain digestive concerns may need to carefully choose their dairy products.
A certain nutrition guidelines In the United States, advise about three cups of dairy products, although personal needs vary.
Many people are not of this quantity, which leaves an open door to consider how milk or cheese could add a microbial variety.
Future food directives
Health experts warn that these results should not lead to large hypotheses on all dairy products.
The study involved a small group of older men and their average dairy intake was lower than national averages, so that the results may not apply to other groups or food models.
However, research adds weight to calls for more personalized food advice. Instead of focusing only on dairy quantity, future guidelines may need to highlight the type of dairy product and its effects on the intestine bacteria Global balance and health.
Little -scale research limits
The study included only 34 participants, most of whom were older men. This limited sample size makes it difficult to apply the results to young people, women or more diverse populations.
In addition, dependence on self -depressed food frequency questionnaires introduces a certain uncertainty.
People do not always remember their eating habits with precision, which can affect the way their dairy contribution corresponds to microbiome changes.
Dairy, gut health and the future
Studies are increasingly highlighting the idea that food choices affect more than just basic nutrition. Milk Consumption, in particular, is now linked to the presence of microbes that could protect against a variety of intestine problems.
“Dairy consumption can influence the health of the host by modulating the structure and composition of the colonic adherent intestinal microbiota,” said Dr. Jiao.
The wider health connection is an active subject, and future efforts may include trials that examine long -term changes.
Researchers plan to know more about how every type of dairy product modifies these microorganisms in people of different ages and horizons.
They also want to understand the range of nutrients, such as calcium or proteins, which could operate alongside intestinal microbes to maintain digestion gently.
The study is published in Nutrients.
