  • A latest examine noticed the results of tomato consumption on the intestine microbiome in pigs.
  • After 10 piglets had been fed a weight-reduction plan of which 10% was freeze-dried tomato powder, their ratio of “good” to “unhealthy” micro organism shifted towards a extra favorable profile.
  • The tomato-fed pigs additionally acquired larger variety of their intestine microbial group, believed to be a signifier of stronger intestine well being.
  • The findings might probably result in dietary suggestions for long-term well being in people.

Wealthy within the antioxidant lycopene and different important vitamins, tomatoes are identified for his or her well being advantages.

However lesser understood are the implications tomato consumption has for intestine well being.

In a brand new examine, researchers examined the results of a tomato-heavy weight-reduction plan on the intestine microbiome utilizing an animal mannequin.

Researchers fed piglets a tomato-supplemented weight-reduction plan for 14 days and located that the stability of their intestine micro organism shifted towards a more healthy, extra favorable profile.

The outcomes had been not too long ago printed in Microbiology Spectrum.

Lead examine creator Jessica Cooperstone, Ph.D., assistant professor within the Division of Meals Science and Know-how at Ohio State College in Columbus, advised Medical Information In the present day:

“Tomato consumption has been correlated to a wide range of optimistic well being outcomes, and they’re the second mostly consumed vegetable in america. About 22% of whole vegetable consumption comes from tomatoes, so we’re desirous about higher understanding the well being results of this generally consumed meals.”

Researchers used 20 male piglets that had been born in the summertime of 2019 on the OSU Swine Facility in Dublin, OH. After they had been weaned from their sows, they had been fed a basal weight-reduction plan for 1 week.

Subsequent, researchers randomly assigned 10 piglets to a tomato weight-reduction plan consisting of freeze-dried tomato powder added to the basal weight-reduction plan. The remaining 10 piglets acquired the management weight-reduction plan, consisting of the basal weight-reduction plan modified to match the tomato weight-reduction plan’s sugar, fiber, and different macronutrient content material.

“We needed to ensure we might present a constant supply of tomatoes to the pigs all through the examine,” Dr. Cooperstone stated.

“In Ohio, we are able to solely develop tomatoes within the discipline for harvest towards the top of summer season, so freezer drying serves as a preservation step. We needed to include the tomato into the basal weight-reduction plan of the pigs, and that weight-reduction plan is powdered,” she added.

The tomatoes from which the powder was derived had been a hybrid grown on the North Central Agricultural Analysis Station of Ohio State College (OSU) in Fremont, OH.

Moreover, to keep away from any non-dietary unfold of micro organism, pigs had been housed solely with different members of their group on one aspect of a walkway. Pens allowed snout-to-snout contact between grouped companions.

On the finish of the experiment, there have been no body-weight variations between the 2 teams of piglets.

The researchers analyzed fecal samples from all of the pigs at first of the experiment, 7 days in, after which once more after 14 days.

Utilizing DNA shotgun genomics, the researchers recognized the micro organism current at every level.

Sequencing detected a shift after 14 days within the ratio of Bacillota (“unhealthy” micro organism) towards Bacteroidota (“good” micro organism).

Each varieties or lineages of micro organism, often known as phyla, include a lot of micro organism, a few of which can be useful or not.

Researchers additionally noticed a larger bacterial variety within the samples of the tomato group, which can counsel a more healthy phenotype.

Whereas variety is considered as useful within the intestine microbiome, a lot stays unknown in regards to the total impression.

Dr. Ashkan Farhadi, a gastroenterologist at MemorialCare Orange Coast Medical Middle in Fountain Valley, CA, not concerned within the examine, questioned what might have resulted if the pigs had been fed common tomatoes versus tomato powder.

As well as, whether or not the amount and period of tomato consumption might have yielded totally different outcomes will not be but identified and should warrant additional examine.

“There are plenty of questions that come out of a superb examine, and this can be a good examine,” Dr. Farhadi advised MNT.

Dr. Farhadi famous that comparisons between any two species are onerous to make definitively.

“We each have intestine germs, [but] are they similar between us? There are not any similar germs between even two people or in a single particular person on two days. Intestine germs are so dynamic that even if you’re wired for a interval of 1 hour, the germs are totally different,” he defined.

Though pigs are usually not people, there’s cause to suspect that tomato consumption would possibly equally profit the human microbiome.

“We [are] gaining a extra detailed understanding of how particular meals impression human well being,” Dr. Cooperstone stated.

“Earlier research have discovered that the gastrointestinal tract of pigs is extra much like people than mice are to people, which is why we elected to do that examine in pigs. Different research have discovered that the 2 main phyla of micro organism within the intestine microbiome are the identical between pigs and people. We hope to maneuver our trials to people sooner or later.”

Talking to Ohio State Information in regards to the examine, Dr. Cooperstone stated that a greater understanding of the results of various meals on intestine well being “might result in extra evidence-based dietary suggestions for long-term well being.”
