多倫多大學卡斯柏教授最近發表將刊登於下個月<分子藥理學>期刊中的一篇研究報告顯示, 吸煙者如果飲適量紅酒, 可以中和香煙中所含毒質, 還可以排除充斥於環境中的多種污染有毒物質. 卡斯柏教授說, 紅酒中所含一種稱為RESVERATROL化合物, 有助於減少煙害. 他尚表示, 這化合物的好處還不止僅限於對吸煙者, 它同時亦是[芳基鹵化煙]之類廢氣的剋星. 人類居住的環境到處充斥排放廢氣物, 燒烤食物濃煙等.....

Study finds more reasons to drink red wine
Monday August 3 4:58 PM EDT
WASHINGTON (Reuters) - British researchers said Monday they had found more evidence that red wine, as opposed to other forms of alcohol, can protect against heart disease.
They said they had detailed information on how substances in red wine can act as antioxidants, which can help stop fat from sticking to artery walls and clogging them up.
Writing in the American Journal of Clinical Nutrition, they said red wine in its natural form worked best, but capsules containing these substances, known as polyphenols, also worked to a degree.
"Red wine but not white wine has antioxidant activity when given to volunteers and this difference is most likely due to the content of wine polyphenols which are abundant in red wine but not in white wine," Shailja Nigdikar, Alan Howard and colleagues at Papworth Hospital in Cambridge, England, wrote.
They said theirs was one of the first studies to break down how this happens in living human volunteers, as opposed to in a test tube or laboratory animals.
In their study, 30 healthy, nonsmoking men aged 35 to 65 were given either a half-bottle of Cabernet sauvignon red wine, a glass of white French table wine with polyphenols dissolved in it, or polyphenol capsules every day for two weeks.
A "control" group got a drink made with 10 percent vodka and lemon soft drink.
Polyphenols include catechin, quercetin, resveratrol and other substances. They are found in grape skins, and thus in purple grape juice. Grape skins are used in making red wine but are removed early on in the process of making white wine.
"In our study red wine consumption in volunteers increased plasma and LDL polyphenols and enhanced antioxidant activity," Howard and Nigdikar's team wrote.
"Red wine but not white wine contains abundant polyphenols, which inhibit the oxidation of human LDL (low density lipoprotein -- the so-called "bad cholesterol" that can block arteries)," they wrote.
Levels of the polyphenols were elevated by 38 percent with red wine, 28 percent with capsules and 27 percent when the red wine polyphenols were dissolved in white wine.
They measured antioxidant activity by looking at plasma lipid peroxides -- byproducts in the blood of the oxidation of fat. Peroxides were lowered 32.7 percent with red wine, 29 percent by the capsules and 28 percent by the polyphenol-white wine mixture. They were not reduced at all by the vodka drink.
The researchers urged that more trials be held.
Several studies have shown that a moderate intake of any alcohol, not just red wine, can help protect against heart disease and perhaps cancer. Moderate means one or two drinks a day and no more.
But heavy drinkers have above-average mortality rates.
A Harvard School of Public Health report said women who consume two to five alcoholic drinks a day have a 41 percent higher risk of developing breast cancer than do nondrinkers.
Green tea is also known to contain polyphenols, as does black tea.

年齡不是葡萄酒的秘密.
常常聽到人們說2000好, 1993差, 1982是夢幻vintage; 到底是甚麽意思呢?
首先問大家一個問題, 對葡萄酒有相當的研究嗎?
[我就連“品牌名”或“產地”的讀法也不清楚. 即使向店員請教, 最多也只得到 : 單寧重, 有豐富的水果味. 這類答案....不知怎樣辦... ]
當你越想越懊惱, 最後在迷惘至極的時候就決定只以價格為基準來挑選, 最後就選了瓶不合適的葡萄油...當這種經驗周而復始, 你就會開始覺得 [喝葡萄酒真麻煩 !]
其實, 就算沒有淵博的葡萄酒知識, 也有選擇優質葡萄酒的方法. 當中最快捷的方法就是知曉 Vintage(葡萄酒的生產年份). 葡萄酒理所當然是由葡萄釀造的, 由於葡萄是農作物, 自然會有豐收和失收的時候; 在適合的天氣和沒有冰雹等災害的情況下, 這一年就能收割到大量優質的葡萄, 這樣的年份稱為 [ Great Vintage], 釀成的酒就算是一般級數的, 通常都會很出色.
不過要注意的是用Vintage來選擇葡萄酒, 對新世界(指釀造葡萄酒的後興國家如智利, 澳洲等) 葡萄酒並不合用, 因為不同Vintage的葡萄酒在新世界中分別並不明顯. Vintage主要是針對舊世界葡萄酒(可以說是歐洲)而言.
舉例來說, 2003年法國夏天酷熱得有人熱死, 但對某些釀酒葡萄來說卻是好天氣, 在法國最大的葡萄酒產地Bordeaux(波爾多), Cabernet Sauvignon 罕有地出現豐收. 因此, 2003波爾多(以Cabernet Sauvignon為主體的波爾多左岸葡萄酒)紅酒十分優秀, 就是價格較廉宜的也應該不錯. 至於法國東南部地方的另一大產區Burgundy(勃根地), 它的情況如何呢? Burgundy主要的葡萄Pinot Noir 因為酷熱天氣而失收. 因此和Bordeaux正好相反, 2003年Burgundy的葡萄酒得到不樂觀這下等評價. 如果要喝美味的Burgundy葡萄酒的話, 推薦大家年份2002的葡萄酒, 因為是得到高度評價 [ Super Great Vintage] . 只不過, 在 [Great] 的年份出產的葡萄酒屬於成熟期長的類型, 飲用時需要特長的 “透氣” 時間.

Château Latour-Martillac CRU CLASSE DE GRAVES
Appellation Pessac-Léognan
Wines at Château Latour-Martillac are made in such a way as to reduce oxidation to a minimum, which is always harmful for their freshness and balance.
The " red " vathouse has special equipment and manual sorting table which enables the harvest that has just been hand-picked under strict supervision, to be de-stalked, crushed and put into vats in record time. The produce of our old vines and that of the younger ones which is used to make our second wine - Lagrave-Martillac Red - ferments in stainless steel vats fitted with electronic temperature control.
Our red wines are aged for 18 or 20 months in oak barrels, half of which are renewed every year. Bottling of every vinetage follows fining with egg whites and blending of the wines selected from the different parts of the vineyard, only the best of which go into the first wine, Château Latour-Martillac.
For the white wine, pickers go through the vines several times selecting just those grapes that are ready and putting them in wooden fruits trays or flat boxes so as not to damage them. The harvest is then pressed traditionally as the press slowly rotates. The must is filtered cold and the clear juice alone is fermented in oak barrels, that are also renewed by half everey year. This way the natural aromas of the grapes are kept intact. Their complexity comes largely from the old grape varieties used by our grandfathers, magnified by the great age. The young vines are harvested in the same way to make a new Lagrave-Martillac White.
The white wines are kept on their lees for over a year, then bottled in dark glass to enable them to develop as dry wines for decades.
CHÂTEAU LATOUR-MARTILLAC red wine and white wine is available at Purple 6 Wine Delivery.

紅酒抗氧化劑酮類物質
紅酒中含有豐富的抗氧化劑「酮類物質」，這些酮類物質的抗氧化能力比維生素Ｅ還強30倍，因此每日一小杯紅酒就可減少這些血管疾病的發生率。
酮類物質主要存在於葡萄皮中，紅酒的製造過程保存了葡萄皮中最珍貴的成分。紅酒中的酮類物質能刺激血管_皮細胞合成一_化_，而達到擴張血管的效果。在飲用紅酒九十分鐘後，會使阻塞的冠_動脈_生擴張作用，因此高血壓及心絞痛的患者，每日一小杯紅酒，可保護心、血管系統。
世界衛生組織(WHO)的研究也發現，法國人血中的膽固醇含量及血壓皆比美國人高，但是美國人的心肌梗塞死亡率是法國人的2.5倍。法國人長壽的祕密就是靠著紅酒。醫學研究也發現，適量紅酒也可減少近五成的心血管疾病死亡率。
新英格蘭期刊上發表的研究報告也顯示，紅酒中的酮類物質對於大腸癌、食道癌、及皮膚癌有預防效果，而喝烈酒及啤酒反會增加大腸癌。每天一小杯的紅酒，有助於食物的消化，也有助睡眠品質的提升。

Red Wine - Heart Health benefits?
Does red wine protect against heart disease? Maybe. Many studies investigated the benefits of red wine suggested that moderate amount of red wine (one drink a day for women and two drinks a day for men) lowers the risk of heart attack for people in middle age by ~ 30 to 50 percent. It is also suggested that alcohol such as red wine may prevent additional heart attacks if you have already suffered from one. Other studies also indicated that red wine can raise HDL cholesterol (the Good cholesterol) and prevent LDL cholesterol (the Bad cholesterol) from forming. Red wine may help prevent blood clots and reduce the blood vessel damage caused by fat deposits. Indeed, studies showed that people from the Mediterranean region who regularly drank red wine have lower risks of heart disease What\'s in Red Wine that are good for heart? Red wine is a particularly rich source of antioxidants flavonoid phenolics, so many studies to uncover a cause for red wine\'s effects have focused on its phenolic constituents, particularly resveratrol and the flavonoids. Resveratrol, found in grape skins and seeds, increases HDL cholesterol and prevent blood clotting. Flavonoids, on the other hand, exhibit antioxidant properties helping prevent blood clots and plaques formation in arteries. Written by Gloria Tsang R.D.
