Studies show wine is heart healthy, but what about the calories?
A glass of wine a day keeps the doctor away. Could this be true? WebMD talks to experts to learn how we can get the health benefits of wine or alcohol while keeping our weight in check.
Do Like the French?
The French diet is often used as an example of how wine can improve heart health. The French have a fairly high-fat diet but their heart disease risk is relatively low. And some have attributed this to red wine.
But there are so many differences between the lifestyle of the French and Americans from their activity levels to the foods they eat. You cannot isolate red wine as the magic bullet for disease prevention says Alice Lichtenstein, DrS, Gershoff Professor at Tufts University.
Choose whichever alcoholic beverage you enjoy, drink it in moderation and try to have it with meals, advise Lichtenstein and Eric Rimm, DrS, a Harvard researcher.
Arthur Agatston, MD, cardiologist and creator of the popular South Beach diet, encourages patients who enjoy alcohol to also drink it with meals.
"Alcohol can stimulate the appetite so it is better to drink it with food. When alcohol is mixed with food, it can slow the stomach's emptying time and potentially decrease the amount of food consumed at the meal," asserts Agatston. His alcohol of choice is red wine due to the antioxidant resveratrol. However, he agrees that any alcohol in limited quantity will provide the same health benefit.
There is a misperception that red wine is abundant in antioxidants. "It does contain some, but they are not always well absorbed. If you want antioxidants, you are better off eating a spinach salad with vegetables than drinking a glass of red wine," Rimm tells WebMD.
Lower Your Cholesterol
Alcohol also can have a very powerful effect and increase HDL "good" cholesterol by 20% if used moderately and in the context of a healthy diet along with regular physical activity, says Rimm. Higher HDL levels are linked to lower risks of heart disease.
"The research evidence points to ethanol, or the alcohol component, of beer, wine, or spirits as the substrate that can help lower cholesterol levels, increase 'good' HDL cholesterol," he says.
Boost Your Brain
A recent study shows a boost in brain power for women who enjoy a little alcohol. The study, published in the Jan. 20 issue of The New England Journal of Medicine, evaluated more than 12,000 women aged 70-81. Moderate drinkers scored better than teetotalers on tests of mental function. Researchers found a boost in brainpower with one drink a day. Moderate drinkers had a 23% reduced risk of mental decline compared with nondrinkers.
With Alcohol, Moderation Is Key: Easy Does It
Just as you shouldn't eat a 12-ounce steak daily, you need to watch your portion sizes of alcohol as well.
What is one drink?
- 5 ounces of wine
- 12 ounces of beer
- 1.5 ounces of 80-proof distilled spirits, such as vodka
The
recommend one drink a day for women and two a day for men. This doesn't mean to can save them up for a weekend party and expect to get the same benefits.Will a Drink a Day Make You Fat?
A drink a day may help keep your brain sharp and heart healthy but what about the calories?
Alcohol supplies calories with few essential nutrients. If you drink alcohol, it needs to be budgeted into "discretionary calories" to maintain a healthy weight according to the 2005 dietary guidelines.
"Most Americans are sedentary, putting them into the lower calorie levels, leaving little room for alcohol, sweets, and extra fats," states Theresa Nicklas, DrPH, a member of the dietary guidelines advisory committee.
It is more important and healthful to select foods packed with nutrients, such as fruits and vegetables, rather than alcohol when calories are limited. The health benefits of moderate alcohol do not outweigh the risks of being overweight or obese, says Nicklas.
An individual on an 1,800-calorie level eating plan only has 195 discretionary calories or the equivalent of a 9-ounce glass of wine or a small dessert. If you want dessert along with your daily allotment of alcohol, you need to increase physical activity to balance your calories to achieve a healthy weight, according to Nicklas.
Double-Edged Sword
A little may be good but too much alcohol can lead to serious problems.
No one should start drinking if they don't already drink, advise Lichtenstein and Agatston. It is well known that alcohol can lead to numerous health problems for many individuals, such as pregnant women and women at high risk for breast cancer (alcohol raises the risk of breast cancer). Individuals with family histories of alcohol abuse should also not drink, says Lichtenstein.
To gain the benefits of good health, do your part to enjoy your one to two drinks per day at mealtime and follow the advice of the dietary guidelines for food, fitness, and weight management.
ACCORDING TO THE RESEARCH CONDUCTED 2006.............
The Benefit: Promotes Longevity
The Evidence: Wine drinkers have a 34 percent lower mortality rate than beer or spirits drinkers. Source: a Finnish study of 2,468 men over a 29-year period, published in the Journals of Gerontology, 2007.
The Benefit: Reduces Heart-Attack Risk
The Evidence: Moderate drinkers suffering from high blood pressure are 30 percent less likely to have a heart attack than nondrinkers. Source: a 16-year Harvard School of Public Health study of 11,711 men, published in the Annals of Internal Medicine, 2007.
The Benefit: Lowers Risk of Heart Disease
The Evidence: Red-wine tannins contain procyanidins, which protect against heart disease. Wines from Sardinia and southwest France have more procyanidins than other wines. Source: a study at Queen Mary University in London, published in Nature, 2006.
The Benefit: Reduces Risk of Type 2 Diabetes
The Evidence: Moderate drinkers have 30 percent less risk than nondrinkers of developing type 2 diabetes. Source: research on 369,862 individuals studied over an average of 12 years each, at Amsterdam's VU University Medical Center, published in Diabetes Care, 2005.
The Benefit: Lowers Risk of Stroke
The Evidence: The possibility of suffering a blood clot–related stroke drops by about 50 percent in people who consume moderate amounts of alcohol. Source: a Columbia University study of 3,176 individuals over an eight-year period, published in Stroke, 2006.
The Benefit: Cuts Risk of Cataracts
The Evidence: Moderate drinkers are 32 percent less likely to get cataracts than nondrinkers; those who consume wine are 43 percent less likely to develop cataracts than those drinking mainly beer. Source: a study of 1,379 individuals in Iceland, published in Nature, 2003.
The Benefit: Cuts Risk of Colon Cancer
The Evidence: Moderate consumption of wine (especially red) cuts the risk of colon cancer by 45 percent. Source: a Stony Brook University study of 2,291 individuals over a four-year period, published in the American Journal of Gastroenterology, 2005.
The Benefit: Slows Brain Decline
The Evidence: Brain function declines at a markedly faster rate in nondrinkers than in moderate drinkers. Source: a Columbia University study of 1,416 people, published in Neuroepidemiology, 2006.
