Short-term effects of alcohol The short-term effects of alcohol consumption range from a decrease in anxiety and motor skills at lower doses to unconsciousness, anterograde amnesia, and central nervous system depression at higher doses. Cell membranes are highly permeable to alcohol, so once alcohol is in the bloodstream it can diffuse into nearly every cell in the body. The concentration of alcohol in blood is measured via blood alcohol content BAC. The amount and circumstances of consumption play a large part in determining the extent of intoxication ; for example, eating a heavy meal before alcohol consumption causes alcohol to absorb more slowly.
But why would non-drinkers smoke more than wine-drinkers and exercise less than any of the other groups? The vast majority of alcoholics are smokers — The health effects of alcohol on very often continue to smoke while abstaining from alcohol.
This would also be true of non-alcoholic ex-drinkers who stopped drinking because of health problems. It would be no surprise to find higher rates of cardiovascular disease among nondrinkers who smoke more than light drinkers — an effect not due to the difference in drinking behavior.
Not surprisingly, the investigators discovered that the lifelong teetotalers among the nondrinkers had lower rates of smoking. Additionally, even among the nondrinkers who did not have a previous history of drinking there may have been those who did not drink because of concern about interaction with prescription drugs.
Unlike many previous studies which have a single category for non-drinkers, this study carefully distinguished between former drinkers and long-term abstainers. Using this distinction, the reputed reduced mortality risk for light drinkers over long-term abstainers was disproven for both men and women.
In the case of males, the confounding effect of grouping former drinkers with long-term abstainers was particularly illuminating. Six statistically significant differences were seen between the two groups. Compared to long-term abstainers, former male drinkers were more likely to be: The last result is somewhat puzzling.
There have been fewer alcohol studies on women than on men, so there is less data available, and the results are less definitive — except to rule-out a definite conclusion that light drinkers have less mortality than long-term abstainers OR former drinkers.
Evidence was found for demographic factors which might account for the mortality results of some studies on women. These factors are unrelated to the physical effects of alcohol.
Both "long-term abstainers and former drinkers were more likely to have low income, had less education, were less likely to be employed and were less likely to be European American than light drinkers Former drinkers tended to be: No adjustment was made to account for former alcoholics being abstainers, nor was it established whether abstension is a cause or consequence of health problems.
But there are many proxy variables, only a few of which can be isolated and quantified. Among those 21 countries, France has the highest per capita wine consumption, high vegetable consumption and moderate consumption of animal fat.
The so-called "French Paradox" of high dietary fat and low rate of cardiovascular disease is mistaken with regard to the animal fat — the French eat a great deal of fish. Japan has very low animal fat consumption and less than half the per capita ethanol consumption of France.
Ireland has the lowest per capita fruit consumption and wine consumption of the 21 countries. Drinking patterns in Finland are very different from those in France.
Wine is often consumed with meals in France, which may reduce alcohol absorption. Using hamsters, the group demonstrated that red wine extract significantly reduces atherosclerotic fatty streaks in the aorta and that this effect is even greater when combined with ethanol.
In contrast to studies that have usually shown increased plasma triglycerides due to ethanol in humans, this study showed reduced triglycerides. Most of the benefits of red wine extract were attributed to polyphenols compounds with multiple hydroxylated benzene ringsalso known to be very effective in preventing cancer.
A polyphenol is a molecule with many phenols and better antioxidant properties. Resveratrol trans-3,4',5-trihydroxystilbenepresent in purple grape juicepeanuts and red wine, is known to be a modulator of lipid and lipoprotein synthesis.
Andrew Waterhouse a professor of hydroxyl chemistry — author of the grape phenolics paper cited above has described resveratrol as "trendy and famous", adding "it is no better an antioxidant than the hundred or so other phenolic compounds in red wine". The greatest benefits of resveratrol may not be due to its antioxidant effects.
Because of these results and because resveratrol enhances SIRT1 activity it is suggested that resveratrol mimics the effects of Calorie Restriction with Adequate Nutrition — although a better suggestion might be opposing some of the health effects of the metabolic syndrome.
Modest doses of ethanol beneficially increases plasma HDL cholesterol and reduces blood pressure while harmfully raising plasma triglycerides, decreasing heart muscle contractility and increasing heart rate.
Heavier drinking increases blood pressure. A six-year study of nearly three thousand men showed nearly four times greater incidence of ischemic heart disease in abstainers as in heavy drinkers and nearly twice the incidence in moderate drinkers over heavy drinkers for the fifth with the highest LDL cholesterol levels.
This might indicate that alcohol is only of benefit for those with high LDL cholesterol the French have high LDL cholesterol and drink heavily, hence the "French Paradox"but it is worth noting that the abstainers in the study were taking more medications and were more likely to be suffering from non-insulin dependent diabetes.
Reduced clotting is another benefit of light ethanol consumption — an effect ethanol shares with aspirin. And as with aspirin, with less clotting there is less chance of coronary artery disease, but a greater danger of hemorrhagic stroke.Excessive alcohol use can lead to increased risk of health problems such as injuries, violence, liver diseases, and barnweddingvt.com CDC Alcohol Program works to strengthen the scientific foundation for preventing excessive alcohol use.

Research suggests there is a gender gap when it comes to drinking alcohol and health risks, but experts tend to. When your stomach is empty, alcohol is absorbed quickly, which means you'll feel the effects within minutes. But eating something rich in lean protein and/or good fat, which are both digested and.
