It's true that some studies have shown that one glass of wine per day may reduce the risk of heart disease in some people. However, more is not better. Excess alcohol can raise blood pressure, blood triglycerides, weight, and increase your risk of cancer. If you don't drink now, it is not recommended to start. If you do drink, do so with moderation.
Moderation is considered less than one drink per day for women and two for men.
Remember, exercise also raises the HDL, without the risks associated with alcohol. Despite the high amount of rodent carcinogens in cancer and purported links to human breast, oral, stomach, liver, colon and pancreatic cancers, extensive research in humans have failed to show any connection between caffeine consumption and cancer. Both the American Cancer Society and National Academy of Sciences' National Research Council report that there is no indication that caffeine influences cancer risk. What about diets that promote higher protein intakes and lower amounts of carbohydrate. Eating too much protein can easily turn into eating too much saturated fat and calories.
