A study published in the January 29 issue of Neurology is good news for all those aging geezers – like the author of this blog, to be sure – who worry about their brain health because if you believe the results of this study, it’s never too late to start doing something positive to maintain good brain function into late old age.
In this study, the researchers took 921 people with an average age of 81 and tested their brain health to make sure that none yet met the criteria for dementia.
They were then followed yearly for 6 years with a food questionnaire.
Over the 6 years, 220 people were diagnosed with Alzheimer’s dementia.
In analyzing the food intake of the entire cohort, those with the highest level of flavonoid intake, an anti-oxidant common in fruits and veggies, were 48 % less likely to be diagnosed with AD than were those with the lowest level of flavonoid intake.
The usual disclaimers have to be pointed out, of course: In a study like this, there are a ton of confounding variables – high blood pressure, activity levels, diabetes, social activities, and on and on – although the researchers, as always, claim they made adjustments for this in their analysis.
And if you are wondering which fruits and veggies stood out as being linked to a lower risk of AD, the short answer is: A ton of them.
Thus, the “good” list stand-outs included pears, apples, olive oil, tomato and tomato sauce, kale, beans, tea, spinach, broccoli, and oranges.
Must note two things, though: No mention of coffee (My note: Surely the researchers much have missed it) but yes, wine was also in that “stand-out” list.
