Tomatoes linked to improved intestine well being, research finds
- A current research noticed the results of tomato consumption on the intestine microbiome in pigs.
- After 10 piglets have been fed a food plan of which 10% was freeze-dried tomato powder, their ratio of “good” to “dangerous” micro organism shifted towards a extra favorable profile.
- The tomato-fed pigs additionally acquired higher variety of their intestine microbial neighborhood, believed to be a signifier of stronger intestine well being.
- The findings may doubtlessly 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 research, researchers examined the results of a tomato-heavy food plan on the intestine microbiome utilizing an animal mannequin.
Researchers fed piglets a tomato-supplemented food plan for 14 days and located that the stability of their intestine micro organism shifted towards a more healthy, extra favorable profile.
The outcomes have been lately printed in Microbiology Spectrum.
Lead research writer Jessica Cooperstone, Ph.D., assistant professor within the Division of Meals Science and Expertise at Ohio State College in Columbus, informed Medical Information At present:
“Tomato consumption has been correlated to a wide range of constructive well being outcomes, and they’re the second mostly consumed vegetable in the US. About 22% of complete vegetable consumption comes from tomatoes, so we’re excited about higher understanding the well being results of this generally consumed meals.”
Researchers used 20 male piglets that have been born in the summertime of 2019 on the OSU Swine Facility in Dublin, OH. After they have been weaned from their sows, they have been fed a basal food plan for 1 week.
Subsequent, researchers randomly assigned 10 piglets to a tomato food plan consisting of freeze-dried tomato powder added to the basal food plan. The remaining 10 piglets obtained the management food plan, consisting of the basal food plan modified to match the tomato food plan’s sugar, fiber, and different macronutrient content material.
“We needed to ensure we may present a constant supply of tomatoes to the pigs all through the research,” Dr. Cooperstone stated.
“In Ohio, we are able to solely develop tomatoes within the area for harvest towards the top of summer time, so freezer drying serves as a preservation step. We needed to include the tomato into the basal food plan of the pigs, and that food plan is powdered,” she added.
The tomatoes from which the powder was derived have 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 have been housed solely with different members of their group on one facet 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 in the beginning of the experiment, 7 days in, after which once more after 14 days.
Sequencing detected a shift after 14 days within the ratio of Bacillota (“dangerous” micro organism) towards Bacteroidota (“good” micro organism).
Each varieties or lineages of micro organism, generally known as phyla, include a lot of micro organism, a few of which can be useful or not.
Researchers additionally noticed a higher bacterial variety within the samples of the tomato group, which can counsel a more healthy
Whereas variety is seen as useful within the intestine microbiome, a lot stays
Dr. Ashkan Farhadi, a gastroenterologist at MemorialCare Orange Coast Medical Heart in Fountain Valley, CA, not concerned within the research, questioned what may have resulted if the pigs had been fed common tomatoes versus tomato powder.
As well as, whether or not the amount and length of tomato consumption may have yielded totally different outcomes will not be but identified and should warrant additional research.
“There are numerous questions that come out of an excellent research, and it is a good research,” Dr. Farhadi informed MNT.
Dr. Farhadi famous that comparisons between any two species are laborious to make definitively.
“We each have intestine germs, [but] are they an identical between us? There aren’t any an identical germs between even two people or in a single particular person on two days. Intestine germs are so dynamic that even if you’re stressed for a interval of 1 hour, the germs are totally different,” he defined.
Though pigs usually are not people, there’s purpose 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 just like people than mice are to people, which is why we elected to do that research in pigs. Different
researchhave 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.”

Chatting with Ohio State Information concerning the research, Dr. Cooperstone stated that a greater understanding of the results of various meals on intestine well being “may result in extra evidence-based dietary suggestions for long-term well being.”
