1. Pomegranate juice enhances memory: Probable. Many studies support the connection, including a recent brain-imaging study that showed that volunteers with age-related memory issues who consumed this antioxidant-rich drink performed better on memory tasks than those who drank a red placebo drink.
2. Red wine staves off cognitive decline: Possible. A growing body of research continues to support the health benefits of drinking wine. One study, which followed a group of men and women over seven years, found that those who consumed moderate quantities of red wine performed better on cognitive tests than those who tended to abstain from alcohol or who consumed beer or liquor.
3. Breast milk boosts cognitive development in childhood: Doubtful. A 2013 comprehensive literature review concluded that although children who were breastfed as infants are generally more intelligent than those who do not, this benefit is most likely because of the parents' socioeconomic status and IQ, not mother's milk.
It’s Time to Stand Up for Science
If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.
I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.
If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.
