Optimizing dietary intake
is good for your brain health…
Eating a healthy, nutritious diet especially rich in flavonoids (nutrients found in abundance in certain fruits and vegetables, as well as in coffee, tea and dark chocolate) could help keep your brain sharp as you get older.
Researchers from Institut National de la Santé Et de la Recherche Médicale (INSERM) France and the Université Victor Segalen
Bordeaux 2 report that people who ate foods naturally high in flavonoids performed significantly better on cognitive
tests than those who reported low intakes of the nutrients.
Known as the PAQUID
(Personnes Agées Quid) study, 1,640 subjects, (average age 77) and free of dementia at the start, were given food-frequency questionnaires
that analyzed their dietary intakes of flavonoids. A range of
assessment tools also were administered to measure the subjects’ cognitive function. Subjects were then tested four times over the next 10 years.
lowest intakes. And those who consumed the most flavonoids maintained their cognitive
superiority after 10 years of follow-up; Subjects with the lowest intakes lost an average of 2.1 points on the Mini-Mental State Examination
(MMSE) while subjects with the highest intakes lost only 1.2 points.
performance declines naturally with age, but the results of the study suggest that this decline could be slowed by increased intake of key flavonoids in the diet.
Not surprisingly, flavonoids have been receiving interest in recent years; A mounting body of scientific evidence: both epidemiological and laboratory-based studies linking a number of key flavonoids with lower risk for some cancers.
A regular diet high in fruits and vegetables is worth following for other health benefits, as well…
“We know that a diet high in flavonoids is also a diet high in fruits and vegetables. In these foods you also find antioxidant vitamins, fiber and other nutrients that may be beneficial to keep in good health
,” the team of scientists explained. “This kind of diet is also associated with less morbidity resulting from cardiovascular diseases, cancer, diabetes. Therefore, to keep in good health, rather than focusing on a specific nutrient, it would more beneficial to adopt a diet with more fruits and vegetables, more fish; Less saturated fat, less salt, less processed foods.
“Only randomized trials would give a confirmation, ” they continued, “but it would be long and expensive, whereas we already know that ‘healthy’ dietary patterns are more likely to be beneficial for health.”
