You have it right. And it is confusing. Thorough research on this topic has left us with a mixed message.
Drinking alcohol on a moderate basis indeed lowers the odds of developing or dying from heart disease. And heart disease is still the leading cause of death in the United States.
Compared to people who dont drink alcohol, moderate drinkers have a:
- 29% lower risk of being diagnosed with coronary artery disease
- 25% lower risk of dying from a heart attack
- 25% lower risk of dying from any heart or blood vessel disease
But an estimated 4% of cancer deaths worldwide are related to alcohol use. Its a little lower in the United States, at 3.5%. The most common alcohol-related cancers in men were mouth, throat, and esophageal cancer. In women, its breast cancer.
The more you drink, the higher the cancer risk. But even moderate drinking raises a womans risk of breast cancer.
For people who dont drink alcohol now, theres no reason to start. But they also shouldnt worry if they occasionally have a drink.
Women at higher than average risk of breast cancer or who are worried about developing breast cancer have a tricky decision as well. To drink or not to drink? Not drinking would eliminate one possible risk factor of for breast cancer.
At the same time, heart disease is more common and deadly among women than breast cancer. A higher risk heart disease might tilt the balance in favor of reasonable alcohol use.
If you do enjoy alcohol, keep your drinking in the moderate range. For women, that means no more than one drink per day. For men, thats no more than two per day.
You dont get any extra heart protection by drinking more. And your risk of cancer and many other problems rises dramatically with higher amounts of alcohol use
One day, advances in genetics may let us more accurately predict who can use alcohol in moderation and who should avoid it completely.
