European wines better for heart than New World, claim scientists

It has long been known that red wine can be good for the heart.
But now it seems that certain traditional wines are better than newer varieties. Scientists have shown that if you want to live a long life, you should opt for a glass of Sardinian red wine over an Australian Shiraz.

New research has found that grapes grown on the Italian island, along with those from south west France, have much higher levels of chemicals that can protect the heart than New World wines.
Experts think the difference could be down to the different climate and environmental conditions, while the traditional production techniques used in the 'Old World' are better at preserving the wine's goodness.
Certain grape varieties only used in France and Italy also have higher levels of beneficial chemicals.
The British team behind the discovery said it could explain why people in these two areas have been found to live longer than inhabitants of many other parts of Europe.
The conclusion therefore is that if people want to protect their hearts and enjoy a long life, they should forego popular New World wines such as Australian Shiraz and instead buy a bottle of French Madiran or a red from the Nuoro region of Sardinia.
Previous studies have suggested that a glass of red wine a day may protect the heart and scientists concluded chemicals called flavonoids that come from the skin and seeds of the grape may be behind this.
Now a new study, published in the journal Nature, has worked out a particular group of flavonoids known as procyanidins are the most biologically active.
Professor Roger Corder of the University of London and Professor Alan Crozier from Glasgow University, suspected wines high in these chemicals may therefore offer greater protection for the heart.
They tested two wines from regions where lots of people have been found to live to a ripe old age - the Nuoro region in eastern Sardinia and the Gers department in south west France. They found both had unusually high levels of these procyanidins - up to 10 times that found in New World Wines.
They believe the chemicals may in some way affect the endothelial cells which line our arteries and can trigger heart problems.
The study did not establish exactly why wines from Sardinia and this area of France had higher levels of the procyanidins.
However Prof Corder, from Queen Mary's William Harvey Research Institute at the University of London, said it may be because the Gers region wines come mainly from a grape called Tannat which contains lots of tannins.
In Sardinia, many grapes also grow at altitude and the extra ultra-violet light they are exposed to could allow more of the chemicals to be produced.
Equally, it could be because both areas use older vines, which reach deeper into the soil and so produce more concentrated wines.
It might also be due to them both using more traditional wine production techniques involving long slower fermentation in wooden casks.
This is thought to retain more of the beneficial chemicals than some of the quicker New World techniques that sometimes use steel containers Prof Corder said other studies had suggested that a chemical called resveratrol may account for the beneficial effects on the heart.
However this is present in only tiny quantities in a wine, unlike procyanidins which can reach levels of one gramme per litre.
Given this, he said an average glass of wine a day could be enough to give you sufficient chemicals to help protect the heart. But based on the findings, he warned not all red wines provide the same benefits. He said: "We have to reappraise the whole idea that red wine consumption is universally good for you because on the basis of our research, we concluded only some wines are going to confer that benefits and many other wines will confer little more benefit than drinking white wine."

Cannonau e la vita diventa più lunga

Una rivista scientifica francese,
Nat ure , pubblica oggi
quello che i vecchi di Barbagia
da anni si tramandano: il Cannonau
allunga la vita. Lo studio
dei ricercatori dell’Istituto William
Harvey dell’os pedale
QueenMary di Londra, afferma
che il vino sardo, e di Nuoro in
particolare, è un elisir di lunga
vita. Il merito è dei polifenoli,
sostanze formate da pigmenti e
tannini, di cui i nostri vini sono
ricchi. I medici hanno esaminato
le cellule delle arterie su cui i
polifenoli, e in particolare i procianidi,
hanno effetti positivi, e i
vini della provincia di Nuoro e
del dipartimento francese di
Gers, famosi per la longevità
delle sue popolazioni. Scoprendo
che i vini di queste zone contengono
livelli di procianidi da 5
a 10 volte superiori rispetto ai
vini australiani, americani o sudafricani
esaminati. Il segreto è
nelle qualità delle uve, nel rispetto
dei tempi di maturazione
e nei «metodi di produzione tradizionali
usati in Sardegna», ha
spiegato Robert Corder, medico
coautore della ricerca. ■MA. SE.

Alla faccia di chi lo voleva importato dagli spagnoli!
Secondo le ultime scoperte pare che fosse in voga già tra i sardi dei nuraghes!
E per ora, prove arkeo alla mano, detiene il primato di vino più antico in the world!!

c'era un ricerca in corso di una università milanese sui ritrovamenti di "aghina antiga".. i nostri "cari amici" giornalisti sardi sono totalmente disinteressati a farci sapere qualcosa di più sugli sviluppi... a candu troppu a candu nudha.
pensa che io lo scoprì dal quotidiano inglese independent.
strana la vita!
