The link between the plants we eat and the health of our intestinal microbiota remains a fascinating subject of study. Researchers have recently highlighted, for the first time, the positive influence of fruits and vegetables on the bacterial diversity of the intestine, even if it is low. These plants contain bacteria capable of colonizing the human intestine and contributing beneficially to the richness of the intestinal microbiota. This discovery is the result of a meta-study published in the journal Gut Microbes, revealing that the presence of genes favoring the production of vitamins and short-chain fatty acids in plants might explain this benefit for microbial diversity, which plays a crucial role in our overall health.
To conduct this study, the researchers first compiled data on the microbiome of 156 fruits and vegetables. Additionally, two studies involving around 2,500 stool samples from babies and adults, coupled with information on their diet, were analyzed. Despite this, bacteria from fruits and vegetables remain poorly present in the human intestine, representing approximately 2.2% of total bacterial diversity. The researchers highlighted that the age of the individual, the frequency of vegetable consumption and the variety of plants consumed play a determining role in favoring a higher proportion of these bacteria.
In addition, good agricultural practices are crucial to maintaining optimal health. The researchers highlighted that all elements impacting the natural microbiota of fruits and vegetables, including agricultural practices, breeding and post-harvest treatments, can directly or indirectly influence the composition of the intestinal microbiota.
