We
all want to maintain healthy brains and well-functioning bodies as we age. So how do we do it? The most powerful tool available to us
appears to be a Mediterranean diet rich in good fat, and yet another 2015 study agrees. [1] In a four-year randomized controlled trial
studying age-related cognitive decline, participants 55–80 years old were
divided into three groups. Two groups
followed a Mediterranean diet supplemented with either 1 liter of extra-virgin
olive oil per week or 30 grams of mixed nuts (walnuts, almonds, and hazelnuts)
daily, and the third group followed a careful low-fat diet. Those on the Mediterranean diet with nuts or
olive oil had better brain function at the end of four years than those on the
low-fat diet. This builds on 60 years of
high-quality studies supporting an omnivorous Mediterranean diet pattern. The low-fat doctrine has dominated the past
half-century, but it’s time to face the good fat facts! Want a quick Mediterranean diet summary? See Fat Is Good,
Bagels Are Bad. For a practical
and easy-to-read resource on the day-to-day application of Mediterranean diet
principles see Good Food, Great
Medicine (3rd edition – especially pages 15-16 on Aging Gracefully). It also includes 185 recipes featuring plenty
of raw nuts and extra-virgin olive oil.
