You’ve got most likely heard individuals say, “An apple a day retains the physician away.” This is a contemporary model, nevertheless: “An apple a day retains dementia away.”
A brand new long-term examine signifies that consumption of sufficient quantities of flavonoid-containing meals lowers the danger of creating Alzheimer’s illness and Alzheimer’s-related illness.

These chemical compounds are highly effective antioxidants that improve immune operate and scale back irritation. Diets wealthy in flavonoids have constructive results on weight, heart problems, diabetes, most cancers prevention and neurodegenerative illnesses.
This present examine centered on the influence of eating regimen on the danger of cognitive decline in older age. The researchers used surveys and medical exams to observe this huge affected person group, who have been a part of the Framingham Coronary heart Examine. The researchers included solely the sufferers who did not present cognitive decline initially of the examine.
For the examine, the researchers recorded consumption of every of the six various kinds of flavonoids and the quantity of every one consumed relative to the remainder of the group. Sufferers in these teams have been examined for flavonoid consumption and the onset of Alzheimer’s illness and Alzheimer’s-related illness.
