Healthy 'Mediterranean Diet' Is Good for Your Microbiome

WEDNESDAY, Feb. 19, 2020 -- The so-called Mediterranean diet is already considered one of the healthiest for your heart, and now scientists say it may give your gut bacteria a boost, too.

The diet is typically high in fruits, vegetables, nuts, beans, olive oil and fish, and low in red meat and saturated fats. The new study finds that older adults who eat a Mediterranean diet tend to have more types of gut bacteria linked with healthy aging.

Could Heartburn Meds Spur Growth of Drug-Resistant Germs in Your Gut?

TUESDAY, Feb. 25, 2020 -- Common heartburn meds may foster the growth of antibiotic-resistant bacteria in the gut, a new research review suggests.

In an analysis of 12 past studies, researchers found that, overall, the evidence supports a link: People who use acid-suppressing medications -- particularly proton pump inhibitors (PPIs) -- are more likely than nonusers to harbor antibiotic-resistant bacteria in the gut.

Why Some High-Fiber Diets Cause Gas -- And What to Do About It

WEDNESDAY, Feb. 5, 2020 -- If you want to reduce bloating when eating a high-fiber diet, try making it carbohydrate-rich rather than protein-rich, new study findings suggest.

Bloating is a common side effect that discourages many people from adopting a high-fiber diet.

For Patients on Blood Thinners, GI Bleeding May Signal Colon Cancer: Study

FRIDAY, Feb. 7, 2020 -- Gastrointestinal bleeding in patients taking blood thinners for an irregular heartbeat should prompt doctors to check for colon cancer, a new study advises.

Researchers looked at more than 125,000 patients in Denmark with the heart rhythm disorder atrial fibrillation (a-fib). They reported that those with gastrointestinal bleeding were 11 to 24 times more likely than others to be diagnosed with colon cancer.

New Study Supports Lowering Age of First Colonoscopy

FRIDAY, Jan. 31, 2020 -- The rate of colon cancer among Americans spikes sharply between the ages of 49 and 50, a new study finds -- supporting the case for earlier screening for the disease.

Researchers say the uptick between those two ages does not reflect an actual increase in the occurrence of colon cancer but the fact that screening for the disease has traditionally begun at age 50. So "latent" cancers that had been present for some time are caught at that age.
