It’s that time again – apples are in season! Not only do apples taste great – they provide powerful health benefits!
A medium
apple is a low-calorie nutrition powerhouse – particularly if you buy organic
and eat the skin. A medium apple
provides 4 grams of fiber, a nice dose of Vitamin C along with being a rich
source of polyphenols (beneficial plant chemicals). Most of the fiber and polyphenols are in
the skin!
Polyphenols
stimulate the body to produce more antioxidants through a process called
hormesis. These plant chemicals are
produced by plants to defend themselves and are designed to be poisonous to
insects.
Because of
our size the doses of polyphenols behave differently in humans and stimulate
our cellular defenses and detoxification pathways. Apples contain multiple types of beneficial
polyphenols including flavanols, catechin, epicatechin, and procyanidins.
Apples
and Alzheimer’s Disease
High
concentrations of polyphenols from apples have been shown to stimulate the
generation of new neurons in the brain – a process called neurogenesis. It is important to note that blueberries,
blackberries, strawberries, and raspberries all produce similar benefits to the
aging brain. The key with all of them
is to buy organic. Organically grown
produce tends to have higher quantities of these beneficial plant chemicals because
it must survive pests without the assistance of synthetic pesticides.
If you
cannot find organic apples make sure you wash them thoroughly to remove as much
pesticide as possible.
A study
following 921 people showed that those who consumed the highest levels of
flavonoids (a type of polyphenol) had 48% lower chance of developing
Alzheimer’s Disease. Apples are among
the richest sources of flavonoids, but remember most of them are in the skin!
