Believe it or not, there is a great deal of merit to the age-old
phrase, "Eat your fruits and veggies ... they're good for you."
That's because they are!
According to a study, fruits and vegetables are packed with antioxidants
that may limit brain damage from stroke and other neurological disorders.
Researchers found rats that ate diets enriched with blueberries,
spinach or spirulina (algae) experienced less brain cell loss and
improved recovery of movement following a stroke.
Why?
Antioxidant and anti-inflammatory components of fruits and vegetables
may somehow reduce the nerve cell injury and death evoked by a stroke.
Antioxidant-Rich Discovery
The study involved four groups of rats -- all fed equal amounts
of food for one month. The first group was fed rat food supplemented
with blueberries, the second group was fed rat food with spinach,
the third group was fed rat food with spirulina and the fourth group
was a control group fed rat food only.
Four weeks following, scientists induced an ischemic stroke in
each rat with a blood clot, and then later removed it. The results
were, to say the least, encouraging:
-
Stroke size in the rats who received blueberry and spinach
supplements was half that seen in the
brains of rats in the control group.
-
Rats that received spirulina supplements had stroke
lesions 75 percent smaller than rats in the control
group.
-
Compared to the control group, rats that ate blueberry, spinach
or spirulina diets demonstrated a greater
recovery of poststroke movement.
The key beneficial ingredient in the fruits and vegetables: Antioxidants,
which researchers explained may offset the burst of free radicals
involved in the cascade of brain cell death caused by an ischemic
stroke. Moreover, the supplemented diets fed to the rats contained
anti-inflammatory components that may help reduce injury (provoked
by inflammation) following a stroke.
