Narrator: This is Science Today. If youíre a vigorous runner and drink moderate amounts of alcohol, you may be in better shape than those who donít. Scientist Paul Williams of the Lawrence Berkeley National Laboratory has been studying the relationship between running and alcohol..
Williams: We know from our past studies that running has benefits in terms of raising HDL, or good cholesterol, lowering blood pressure, reducing weight ... 307 We know that alcohol raises HDL as well and so we looked at these runners both in terms of how many miles they were running and how much alcohol they were consuming.
Narrator: Williams found a big difference in those who ran a lot and drank moderately.
Williams: At least in terms of HDL, or good cholesterol and in fact there was five times as many men who had the desirable level of good cholesterol who were running at the highest mileages and drinking two drinks per day as compared to the teetotalers, who are running less than ten miles per day.
