Want to remain healthy? Drink red wine!

It may soon be time to throw out all those
anti-aging and anti-wrinkle creams straight out of the window, for it seems
that all it takes to hold back the effects of ageing is a compound found
in red wine, a new study has found.
In a study on a mouse model, researchers
found that grapes, peanuts and mulberries contain a compound called resveratrol
which, when given to overweight mice, helped them to not only live a substantially
longer life, but also led to them having healthier hearts and livers, as
well as improving insulin sensitivity.
The team states that the compound works
by boosting the activity of sirtuins — proteins that boffins believe defend
cells against damage and illness associated with old age.
When sirtuins become activated, they start
altering glucose and insulin production, fat metabolism and cell survival.
Resveratrol boosts this mechanism.
Though previous studies have shown that
resveratrol can extend the lifespan of fruit flies and worms by almost
30 per cent and fish by nearly 60 per cent.
This was the first time however; that such
a study was conducted on a mammal, leading researchers to start clinical
trials on a pill based on the compound to see whether or not it can extend
life and stave off age-related disease in humans.
Dr David Sinclair of Harvard Medical School,
in Boston, Massachusetts, one of the researchers, said that the results
of the study showed positive clinical indicators for a pill for humans.
"The striking thing is this molecule
has extended the lives of every laboratory organism we have fed it to.
The healthspan benefits we saw in the obese mice treated with resveratrol,
such as increased insulin sensitivity, decreased glucose levels, healthier
heart and liver tissues, are positive clinical indicators,” Nature quoted
Dr Sinclair added that as mice were closer
evolutionarily to humans, boffins were hopeful that the compound would
have many beneficial effects on humans.
"Mice are much closer evolutionarily
to humans than any previous model organism treated by this molecule, which
offers hope that similar impacts might be seen in humans without negative
side-effects. They may mean we can stave off in humans age-related diseases
such as type 2 diabetes, heart disease, and cancer, but only time and more
research will tell," he said.
