White wine ‘good for you’

The health benefits of a glass of red wine are well known, but new research has found a tipple of white could also protect the heart.

Researchers from the University of Connecticut in the US found that rats who were given the equivalent of one or two glasses of white wine suffered less heart damage during cardiac arrest than rats who were fed water or grain alcohol, according to New Scientist.

The benefits from the white wine were similar to those found after animals ingested red wine – or the wonder ingredient found in grape skin – resveratrol.

Previously, it was believed only wine made using grape skin could prevent heart damage.

“The flesh of the grape can do the same job as the skin,” molecular biologist Dr Dipak Das said.

“In lab rats that suffered heart attacks, the animals that received wine or polyphenols experienced less heart damage, compared to rats fed water or straight liquor.

“Their blood pressure and aortic blood flow plummeted less drastically as well.”

Molecular tests of heart cells suggest white wine protects mitochondria.

Director of the Hatter Institute for Cardiology Research in South Africa, Professor Lionel Opie, said Das’ evidence proved white wine protected lab rats, but said human heart attacks occur from blood clots and diseased arteries and not necessarily mitochondrial failure.

Other experiments conducted using dogs showed benefits derived from red wine, but not white, Opie said.

But Das expects similar studies to soon prove white wine’s worth.

“We can safely say that one to two glasses of white wine per day works exactly like red wine,” he said.
