Compared with eating carbohydrates, eating protein—particularly protein from plants— was associated with lower odds of later developing cognitive declines, according to a Harvard study in the January 2022 issue of The American Journal of Clinical Nutrition.

Among people with chronic heartburn, sleeping on the left side appears to help backed-up stomach acid leave the esophagus faster than sleeping on the right side or back, according to a study in the February 2022 issue of The American Journal of Gastroenterology.

When doctors say that it's okay to take proton-pump inhibitors (PPIs) "on demand" for chronic heartburn, the advice doesn't apply to everyone. PPIs inhibit the production of stomach acid, which can back up into the esophagus and can cause pain (heartburn) and damage the lining of the esophagus. People with damage to the esophagus often stay on PPIs long-term to prevent further problems. People without damage to the esophagus can take a short course of PPIs as needed.

Psychedelic drugs such as psilocybin (found in "magic mushrooms") and 5-MeO-DMT (a compound derived from toad venom) are being tested for treating cases of depression that don't respond to standard treatments. New depression approaches are needed since current treatments don't work in nearly half of patients. Hallucinogenics may change longstanding thought patterns or promote new connections in brain neurons. Benefits of psilocybin on mood appear to be long-lasting. FDA approval for psilocybin will likely take several more years.

Everyone feels bloated at times after eating. Bloating is a feeling of tightness, fullness, or pressure in the belly that comes along with abdominal swelling and mild to intense pain. Excessive gas buildup from a sluggish digestive system and problems digesting certain foods are the leading causes. While most bloating goes away after a while, for regular occurrences, people should examine their diet for trigger foods and use over-the-counter anti-gas remedies as needed. In cases of frequent or extended bloating, a doctor should see if other problems are present.
