Possibility of beneficial effects of tomato intake on intestinal flora
A diet rich in fruits and vegetables is known to have a positive effect on the gut microbiota, but little is known about which fruits or vegetables have a positive effect. The purpose of this study was to elucidate the relationship between tomato intake, which accounts for 22% of vegetable intake in the West, and intestinal microbiota. A 14-day study was conducted on 20 piglets as a physiological model of human metabolism, divided into groups on diets with and without tomato powder. The microbiome was sampled from the rectum at three time points: day 0 (baseline), day 7 (midpoint), and day 14 (end). DNA sequences were determined using shotgun metagenomics and analyzed using MG-RAST.
There was no difference in body weight or food intake between the two treatment groups. The tomato powder group showed a higher Bacteroideta/Bassilota ratio and higher alpha diversity, indicating a shift towards a more favorable phenotype. Both phylum and genus level analyzes showed changes in the overall microbiome profile over time, but not with tomato intake. These data suggest that short-term tomato consumption may have beneficial effects on the gut microbial profile, suggesting the need for further investigation in humans.
