Alcohol
There are known benefits to having a glass of wine with dinner or even a beer in moderation. Yet, even with evidence of positive effects, alcohol continues to be one of the worst dangers to your health. An American study followed 200,000 women for over 14 years, monitoring their lifestyles and diet, and found that those who were postmenopausal and drank more than a single glass of alcohol a day had a nearly 30% increase in breast cancer than those who did not drink alcohol.
In fact, alcohol is second to tobacco for being a leading cause of cancer. The World Health Organization stated after gathering sufficient evidence that alcohol is the main cause of esophageal, mouth, liver, colorectal, and breast cancer.
