World Digestive Health Day: Daily habits that protect your gut for life

Tue, 26 May 2026 08:00:00 -0500

Digestive health usually gets attention only when something goes wrong. But the truth is, good digestive health is built quietly, through small daily habits repeated consistently over time.

As we recognize World Digestive Health Day this month (May 29), it’s worth stepping back from the trends, supplements, and internet “gut hacks” to focus on what actually works.

Omar Khokhar, MD, a gastroenterologist at OSF HealthCare, says your digestive system is remarkably resilient and if you support it well, it often returns the favor for decades.

One way to avoid digestive issues and inflammation, Dr. Khokhar says, is to avoid eating convenience or ultra processed food.

Avoid ultra processed food

“So for me, ultra processed food is something that comes out of a wrapper, out of a box, out of a can. It’s something that was made in a factory 300 miles away, two months ago that you now see in your local grocery store. So, there is a convenience factor, but we're starting to see that we're paying for that convenience because those foods are difficult to digest and they can result in inflammatory changes to your gut.”

Dr. Khokhar notes that while genetics can influence the risk of conditions such as celiac disease, inflammatory bowel disease and digestive cancers, daily habits still play a major role in long-term gut health. He says research now shows that when the lining of your gut is disrupted, it can have negative impacts.

“So, the more that we don't do on a daily basis, whether it's fiber, having good bowel movement, making sure we keep a good microbiome, that may result over time in disruption of the mucosal or lining of your stomach and your intestine,” he says.

When that happens, Dr. Khokhar points out, the body will absorb things it shouldn’t, and it won’t be getting what nutrients it should be getting.

If you can only do two things to improve your gut health, Dr. Khokhar says adopt these two habits.

“Flush the pipes. Make sure you drink enough water. Make sure you get enough fiber – whether that’s in diet, whether that’s a supplement, it really doesn’t matter to me at this point. If you get enough fiber and you flush your pipes and you’re evacuating your G.I. tract, it’s going to help remove the waste product.” He adds, “Once you remove the waste product from the colon, everything else can flow down.”

For fiber, Dr. Khokhar says focus on foods found around the perimeter of the grocery store, including fruits, vegetables, and lean proteins.

Walk after meals

One other good habit to consider – taking a walk after meals. Dr. Khokhar advises even short walks can improve digestion and reduce discomfort.

“After you eat, go for an eight-to-10-minute walk. The activity helps everything, literally from a gravity point of view, a physical point of view, a gas expulsion point of view.” He adds, “It almost helps you reset and recalibrate before you inevitably in our society – we sit back down.”

A final point from Dr. Khokhar – do not to ignore persistent abdominal pain or major changes in bowel habits. He warns those symptoms can sometimes signal more serious conditions, including colon cancer.

Dr. Khokhar is a gastroenterologist practicing at OSF HealthCare in Bloomington, Illinois.

Infant nutrition misconceptions, part four

Tue, 07 Jan 2025 08:00:00 -0600

Author's note: This is part four of a four part story on infant nutrition misconceptions. Read part one here, part two here and part three here.

Bringing a new baby home raises the focus on their and mom’s well-being. Toward the top of the list: what and how the child is being fed.

Whether you choose to breastfeed or use formula, misconceptions about infant nutrition are everywhere. Xandra Anderson, a certified lactation consultant at OSF HealthCare, cuts through the noise.

Breastfeeding takes up more of my time than formula feeding.

Choosing formula over breastfeeding is accepted, Anderson says. But she hears some moms do it for the wrong reason: they think it’s quicker, and they can even hand off baby to be fed while they catch up on shut eye.

Anderson counters: Studies have shown that breastfeeding moms get more sleep than formula feeding moms.

“You’re getting up, making the bottle and cleaning the bottle. Instead of being out of bed for 15 to 20 minutes [to breastfeed], you’re out of bed for 45 to 50 minutes. You try to go back to sleep, and baby is up again,” Anderson says.

Breast milk doesn’t keep a baby full.

It’s “complete nutrition,” Anderson says. Breast milk may be easily digestible, but that’s a benefit, not a problem.
Switching formulas is OK.

Anderson recalls the 2022 formula shortage in the United States, leaving some parents scrambling to find more of the formula that works.

“Switching formulas can actually upset the baby’s digestive system,” Anderson warns. “All formulas, while safe, are different. Some are lower lactose. Some are dairy free. If we’re switching because we’re trying to find formula, that can mess up their gut flora, potentially for life.”

If you run out of formula, talk to a health care provider about what to do.
Formula is safer than breastfeeding.

Some formula is ready to drink out of the package. Others need some work. You should follow the formula’s sterilization instructions to ensure you’re killing any bacteria. The United States Centers for Disease Control And Prevention says cronobacter infection is one possibility. These are “rare but serious,” the CDC says, and could result in death. If your baby becomes sick, take them to a provider right away. Lethargy, fever, excessive crying and poor feeding are common symptoms to watch for.

“If you’re breastfeeding, there’s not a lot of chances for that cross-contamination,” Anderson says. “If you’re outside in the garden and messy and sweaty, you can still breastfeed.”
