Plant-based and plant-centric diets have been big buzzwords lately, and a string of new research will bolster not only people who’ve followed those trends, but anyone interested in tapping the benefits of plants through even just a few extra servings of them. Here, we explore some of the most interesting recent studies, and their takeaways, that you might want to know about.
Swapping plant proteins for animal proteins, for just one or two servings a day, could lead to a small reduction (about 5 percent) in three main cholesterol markers, helping with cardiovascular disease prevention, a recent study published in the Journal of the American Heart Association suggests. What’s more: you may be able to boost those health benefits by combining the plant proteins—i.e. lentils, nuts —with other foods known to lower cholesterol, such as high-fiber oats and plant sterols.
Keeping the brain young
Researchers showed, again, that mom was right about eating those greens. Turns out it may pay off particularly as you age, according to a recent study in the American Academy of Neurology’s medical journal Neurology. The research team found that people who ate at least one serving of leafy greens a day had a slower rate of decline on memory and thinking tests than people who never or rarely ate these vegetables—with the difference comparable to being 11 years younger in age, according to study author Martha Clare Morris of Chicago’s Rush University Medical Center.
And then to back up the eat-your-colors advice, another study published in the Journal of Agricultural and Food Chemistry tested the potential of vinegar made from blueberries for improving cognitive function in people affected with Alzheimer’s disease. The theory was that because blueberries are packed with bioactive compounds, and fermentation can boost the bioactivity of some compounds, then a fermented blueberry product might help to stop the breakdown of acetylcholine, a signalling compound found in lower levels in the brains of people with Alzheimer’s.
The study, conducted in mice, found that the fermented product could restore cognitive function in mice. Further testing is clearly needed, but the researchers say that their study points to the possibility that blueberry vinegar may be a promising food to help treat cognitive decline related to aging.
