Can the compound found in plants slow the ageing process and help
tackle Alzheimer's? Food writer Giulia Crouch finds out
There's a new buzzword in town when it comes to health:
While scientists have been investigating the plant compounds forgood
years, the term has now caught the public imagination - and for
reason.often
A growing body of evidence shows that eating a diet high in these
clever natural chemicals offers numerous health benefits, improving everything from heart and metabolic health to lowering the risk of neurodegenerative diseases, such as Alzheimer's.

Polyphenols are a group of phytonutrients (though the terms are
and erroneously used interchangeably), naturally occurringchemicals
in plants that help to protect them in nature from threats such aswith a
insects and UV light, and, as it turns out, also help to protect us
when we eat them
They are found in high concentrations in fruits and vegetables with
deep or vivid colours such as beetroot, blackberries, black olives,
very red tomatoes and dark, leafy greens. As well as protecting the
plant, phytonutrients - including polyphenols - also provide it
strong pigment. The same is true for strong tastes: the morediscovered
cough-inducing an extra virgin olive oil, the higher the likely concentration of polyphenols. Tea, coffee and dark chocolate are
excellent sources.
There are thousands of types of phytonutrients – we haven’t
them all - such as resveratrol in red wine, ellagic acid in walnuts
and catechins in tea. And single ingredients have multiple
phytonutrients - tomatoes contain polyphenols (flavonoids and
flavanones) as well as carotenoids (lycopene, phytoene and beta
carotene).
Trials have shown they all do different things for our health.
