Is a glass of wine the key to good kidney health?

There's been plenty of research around the goodness of red wine, but it turns out white wine has its own health benefits.

In a recent episode of Superfoods, journalist Kate Quilton travelled to Italy in order to uncover the ways white wine can actually help our health.

She met researcher, Alberto Botelli, who believes white wine has the scientific components to combat inflammation in the kidneys.

So, why does he think so? Apparently white wine has the "same active compounds of olive oil: tyrosol, hydroxic tyrosol and caffeic acid," he said.

These three compounds, known as monophenols, have been known to be the exact molecules that make olive oil a healthier option for us to consume.

Alberto believes that this ingredient can boost our kidney health. "Kidney disease is an inflammatory disease," he says. "These compounds have an anti-inflammatory effect."

To test his theory, Alberto took inflamed cells and treated them with a very small amount of tyrosol from white wine. He then conducted a human trial, where group of both healthy participants and those with chronic kidney disease were split in two, with one group adding extra virgin olive oil to their diet, and the others consuming the same amount of oil, plus a small glass of white wine with lunch and dinner.

The results?

"Drinking white wine and oil had a dramatic effect," said Alberto. "We can say that white wine is no longer the ugly duckling of the wine world."

As inflammation in the body can be affected by an overproduction of molecules called cytokines - molecules which tell cells how to respond to infection or trauma – Alberto's studies found that white wine and olive oil enjoyed together had a better effect on the kidneys than the consumption of olive oil on its own.
