That's Fit

So maybe one alcoholic drink per day is healthy. But don't pour that second one just yet -- it could be the very thing that erases the positives effects of the first.

Several studies have shown that light drinking may lower the risk of death and the development of heart disease. One recent Canadian study found that after one drink, blood vessels in participants were more dilated, reducing the work the heart had to do. But, after two drinks, the heart rate, amount of blood pumped out of the heart, and the action of the sympathetic nervous system all increased. The ability of the blood vessels to expand was also diminished. Hypertension, heart failure, and sudden death all can occur when these factors are in place.

Here's the deal: Have one drink and be well. Have two or more and you could stress your system. Now, we're talking regular consumption here, not the occasional indulgence. And get this: The American Heart Association does not recommend that anyone start drinking one drink per day to prevent heart disease. Reducing your risk through proper diet and exercise is much more effective than incorporating alcohol into your day.

Incidentally, if you are going to have one drink, make it red wine, the stuff believed to have the most protective properties.
