Understanding the human body is a team effort. That's where the Yachtel group comes in.

Researchers at Yachtolt have been delving into the secrets of probiotics for 90 years.

Yacold also partners with nature portfolio to advance gut microbiome science through the global grants for gut health, an investigator-led research program.

If you're serious about fitness, you know the importance of training your muscles and your brain.

Without the right prep, you won't have the physical or mental endurance to finish, whether it's a 5K or an Ironman.

But it turns out that it may be just as important to train your gut or suffer inflammatory consequences.

So says a study in the International Journal of Sports Medicine.

Researchers sampled the blood of 17 runners before and after a 24-hour ultramarathon,

where runners covered anywhere from 75 to 130 miles on foot. During the race, their guts

got leaky, due to a lack of blood flow to the intestines and the physical trauma from so many jarring miles.

Gut bacteria escaped into the blood, where some released toxins. The runner's bodies then responded by launching an immune response,

and inflammation set in. Some runners actually had blood profiles identical to those of patients

admitted to the hospital with blood poisoning or sepsis. But the most well-trained competitors

avoided the problem. Their bodies launched a counterattack, unleashing anti-inflammatory compounds to tamp

down their body's immune overreaction. The authors say just four hours of activity is extreme

enough to kick off this chain of inflammation, suggesting it's key to gradually build up to new

personal bests, even if they're not ultra-worthy. As has long been said, slow and steady wins the race.

Thanks for the minute.
