The study examined health records for nearly 1,800 adults between 46 and 77 years-old in the United Kingdom. Participants, who are all part of the biomedical database UK Biobank, completed a Fluid Intelligence Test (FIT) at the start of the study between 2006 and 2010. The group then had two follow-up assessments in 2012-13 and 2015-16. All of these tests gave researchers a snapshot of the group’s ability to “think on the fly” as they aged.

“I was pleasantly surprised that our results suggest that responsibly eating cheese and drinking red wine daily are not just good for helping us cope with our current COVID-19 pandemic, but perhaps also dealing with an increasingly complex world that never seems to slow down,” principal investigator Auriel Willette says in a university release. “While we took into account whether this was just due to what well-off people eat and drink, randomized clinical trials are needed to determine if making easy changes in our diet could help our brains in significant ways.” …

It really does sound too good to be true.  Red wine and cheese to fight Covid and Alzheimer’s.

Results:Daily cheese intake strongly predicted better FIT scores over time (FH-: β= 0.207, p < 0.001; ɛ4–: β= 0.073, p = 0.008; ɛ4+: β= 0.162, p = 0.001). Alcohol of any type daily also appeared beneficial (ɛ4+: β= 0.101, p = 0.022) and red wine was sometimes additionally protective (FH+: β= 0.100, p = 0.014; ɛ4–: β= 0.59, p = 0.039). Consuming lamb weekly was associated with improved outcomes (FH-: β= 0.066, p = 0.008; ɛ4+: β= 0.097, p = 0.044).
