Specifically, the researchers found that the habitual yogurt eaters had lower rates of Bifidobacterium-positive proximal colon cancers. Proximal colon cancer is a type of colon cancer that occurs on the right side of the colon and can have worse survival outcomes than cancers that occur in the distal colon, which is on the left side.

Ugai says the bacteria in yogurt appear to promote an overall healthy balance of bacteria in the gut. And that, in turn, promotes a strong and healthy gut barrier, which is important, because when the gut barrier becomes too permeable, it can lead to inflammation and increase the risk of colon cancer.

"My message is, if you like yogurt, go for it," Ugai says.

The findings are in line with prior studies that have linked yogurt intake to a lower risk of colon cancer, says Dr. Chris Damman, a gastroenterologist and professor at the University of Washington who studies the intersection of the microbiome and metabolic disease.

Yogurt is a fermented food, meaning it is produced when microbes break down sugars in foods in a way that produces complex flavors and prevents them from spoiling. One randomized controlled trial found that people assigned to eat a diet rich in yogurt and other fermented foods — such as kefir, fermented cottage cheese, kimchi and kombucha tea — for 10 weeks had lower markers of inflammation and improved diversity of microbes in their gut.

Damman says that along with fiber, healthy fats and nutrients known as polyphenols found in plant-based foods, yogurt and other fermented foods are a staple of a healthy gut.

"These are the common denominators across culinary traditions and healthy eating," he says.

From Middle Eastern cream cheese-like labneh to Persian abdoogh khiar soup and Indian raita, cultures around the world have long embraced yogurt as a culinary staple.

But before adding yogurt to your diet be sure to check the nutrition label. Research has found that, despite its health halo, many yogurts can be loaded with added sugar. Your best bet is to stick with yogurts without added sugar. Add some berries, bananas or other fruit if you miss that hint of sweetness.

Heat compromises blood flow to the gut and leads to excessive sweating, which can cause dehydration, cramping, exhaustion and fainting. Muscle glycogen, the body's stored form of glucose, is used up more quickly when it is hot, impairing endurance performance, says Tipton.

At his annual Super Bowl news conference Monday, NFL commissioner Roger Goodell strongly supported the league’s policies designed to promote diversity at the club-employment level and said they would continue.
