Mediterranean Diet: Should you drink wine or eat grapes?
The French Paradox
In studies conducted in 1992 found that in southern France, mortality rates from heart disease was lower than expected despite the consumption of diets high in saturated fat. Researchers attributed the impressive impact lower heart disease, 50 percent less than in the States of the United States, with consumption of red wine. Since then, the possibility that drinking red wine may protect our heart arteries, has made the topic "wine and health" extremely popular. In fact, research has shown that moderate drinking and two 8-ounce glasses for men and one glass for women per day, red wine may increase HDL cholesterol, the "good" boy, lower LDL cholesterol, "bad", to avoid oxidation of LDL, and free radicals.
What is the secret in the wine?
Since the discovery of the "paradox French "puzzle in 1992, researchers have been trying to determine why the wine has a cardiovascular protective effect. While studies have focused in the antioxidant properties of red wine, the evidence suggests other mechanisms by which it might be beneficial to our health. The research points to a group of substances called polyphenols, which are found in plants and are abundant in grapes. Polyphenols are part of a larger family known as phytochemicals.
Phytochemicals: Future Medicine
The word "phyto" means "plant" in Greek. Phytochemicals are nonnutritive chemicals in plants that protect against disease. Many fruits and vegetables contain a variety of phytochemicals, in fact, researchers have identified more than 900 different phytochemicals in food and are not, however, because every day they discover new ones. It is estimated that there may be more than 100 different phytochemicals in just one serving of fruit or vegetables.
Studies have long shown that phytochemicals are present in plants to protect them, but only recently have we learned which are also crucial in protecting humans against disease. We know that people who consume plant foods regularly have a lower incidence of heart disease than people who do not include them in your diet.
How can phenol-phytochemicals protect our arteries?
Polyphenols can protect our arteries through the following mechanisms:
• The reduction of LDL cholesterol in the blood. A study to assess the effect of consumption moderate Sicilian red wine on cardiovascular risk factors found that at the end of the period of consumption of red wine, 4 weeks, LDL cholesterol, and oxidized LDL had decreased significantly, while HDL cholesterol and total antioxidant capacity of the blood had risen ¹.
• Recycling of vitamin E as an antioxidant. This is very important because vitamin E represents the first line of defense against LDL oxidation. Once vitamin E is exhausted, LDL cholesterol is no longer protected until the vitamin can be reactivated by agents such as polyphenols.
• Increased production of nitric oxide, a substance that causes arteries and veins to relax.
• Preventing platelets from sticking to the walls of the arteries. Platelets are small particles in the blood that play a role important in the clotting process ².
Red against white wine
White wines have shown the ability to prevent LDL oxidation, but are generally not as effective as red wines. the polyphenol content of red wine may be approximately 20 times higher than in white wine and has been observed in several studies that the potential antioxidant in red wine is six to ten times higher than white wine. About eight times more of white wine is required to produce an effect equal to red wine in preventing the oxidation of LDL cholesterol. Three factors account for these results:
• grape skins are not included in the production of white wine.
• Wine Red is made from whole grapes, including skins
• The skin of red grapes contain higher amounts of polyphenols in the skins of white grapes.
The wine and grapes for healthy arteries?
If the polyphenols in grapes are mostly in the skin, you may only have red grapes or red grape juice, which is also done grape skins, and obtain the same beneficial effects as drinking red wine? Yes we can, researchers tell us.
This study, among others, showed that red grape juice and red wine without alcohol can significantly reduce arterial disease by reducing the level of oxidized cholesterol, preventing platelets stick, and improving the production of nitric oxide ³. In another study, grape juice was more effective than red wine or red wine without alcohol in inhibiting arterial disease in the same dose of polyphenols. The researchers concluded that grape juice or red wine without alcohol are an excellent alternative to red wine when it comes to disease of arteries?.
Conclusion
Although research has shown that in the absence of contraindications, moderate red wine drinking, two 8-ounce glasses for men and one glass for women per day, may be beneficial in patients who have cardiovascular disease, health effects and can disappear very quickly have serious health consequences when drinking abuse. And since studies indicate that most of the beneficial effects of drinking red wine are attributable to the polyphenols present in grapes, one can conclude that a diet that includes grapes and other fruits and vegetables containing polyphenols may be even more beneficial.
