(Catharine Paddock/ Medical News Today) — Men who follow a healthful diet could be protecting their brains, according to a new study that tracked a large group of men for more than 2 decades.
Researchers from the Harvard T.H. Chan School of Public Health in Boston, MA, analyzed data from a study that had followed 27,842 men for 26 years.
The men had all filled in detailed surveys about their food and drink intake at the start of the study in 1986 — when they were aged 51 years, on average — and then every 4 years until 2002.
The follow-up lasted until 2012, by which time their average age was in the mid- to late-70s.
During the last few years of the follow-up, they had also completed short tests to find out whether they had noticed any decline in their own ability to think and remember things. (…)
