Your Favorite Herb Could Soon Become a Key Treatment for Alzheimer’s

It turns out two simple herbs could hold the promise of a better future for those living with Alzheimer’s. In 2025, researchers at The Scripps Research Institute synthesized a form of carnosic acid, a compound found in rosemary and sage that, in preclinical mouse models, reduced brain inflammation, boosted synaptic density, and improved memory markers linked to Alzheimer’s disease. The best news? The ingredient is already on the FDA’s Generally Recognized as Safe list, which may make it easier to actualize human trials as soon as possible.

Scientists Discovered a Huge Health Benefit of Coffee

The past 12 months have brought plenty of good news for coffee drinkers. That includes a study published in the journalNature Microbiology,which found that regular coffee drinkers tended to have higher levels of certain beneficial gut bacteria than those who didn’t consume coffee.

As the researchers noted, these benefits likely didn’t come from caffeine. Rather, the polyphenols in coffee may act as prebiotics, feeding beneficial microbes linked to better digestion, immune support, and reduced inflammation. The scientists underscored that there’s still a lot of work to be done to fully understand these findings, but that their research adds to the growing body of evidence that it’s than fine to enjoy your morning cup of Joe.

Bananas Could Be Wrecking Your Smoothie’s Superpowers, Study Suggests

Unlike coffee drinkers, people who love banana smoothies got a bit of harsh news this year. A new study published in the journalFood & Functionfound that smoothies made with bananas had up to 84% lower “flavanol absorption” — absorption of antioxidant compounds linked to heart and brain health — compared with smoothies made with a berry base.

This unfortunate effect is caused by an enzyme in bananas called polyphenol oxidase, which degrades flavanols before the body has a chance to absorb them. So, next time, maybe enjoy that berry smoothie for breakfast and have a banana as an afternoon snack instead.

These Are the Most and Least Processed Foods at Your Grocery Store

Ultra-processed foods made plenty of headlines this year, with readers seeking out all the information they could about how these foods may affect their health. But consumers also wanted to understand which foods are considered “ultra-processed” in the first place.

In 2025, a research team at Mass General Brigham in Boston created a platform called TrueFoodwhich analyzed the most and least processed grocery foods commonly found at Whole Foods, Target, and Walmart, even breaking down the products by grocery departments like “soups,” “pasta,” “meat,” and “cheese.”

Within certain grocery categories, their data revealed which options are most and least processed. For example, in the yogurt aisle, Wallaby Organic Lowfat Plain Kefir ranked as the least processed option, while Chobani’s Flip S’ s Sweet Vanilla Low-Fat Greek Yogurt qualified as the most processed.

Why Scientists Are Turning to Oysters to Fight Drug-Resistant Superbugs

Drug-resistant bacteria are a major concern for the scientific and medical communities — and one group of Australian researchers believes they may have found the solution within oysters. Their 2025 study observed that antimicrobial proteins in the blood (hemolymph) of Sydney rock oysters can eliminate specific bacteria and slightly enhance the effectiveness of conventional antibiotics.

“What I find particularly exciting about this study is how it represents a shift in our approach to fighting superbugs, because rather than simply developing new versions of existing antibiotics — a strategy bacteria quickly adapt to — we’re exploring entirely different mechanisms of action inspired by nature,” Angelo Falcone, MD, an integrative medicine physician and founder of Dignity Integrative Health and Wellness, who was not involved in this study, shared with Food & Wine.

Per Falcone, “We shouldn’t expect oyster-derived antibiotics on pharmacy shelves tomorrow, but this research opens promising new avenues in our ongoing battle against antibiotic resistance, which is a crisis that demands exactly this kind of innovative thinking.”
