Alcohol is a brain toxin and a
carcinogen linked with several types of cancer, including: head and neck,
esophageal, liver, breast, colorectal, etc. Ethanol breaks down to
acetaldehyde, a substances that damages DNA and proteins. Alcohol also
generates reactive oxygen species that also damage DNA, proteins, and fats through
oxidation. It impairs ability of body to absorb a variety of nutrients and
increases levels of estrogen in the blood. People often ask, “How much alcohol
can I drink safely?” News releases recently have stated that ingesting any
amount of alcohol increases one’s risk for cancer. Also be aware that when
tobacco and alcohol are used together, the risk rises higher than either one
separately. Prevention strategy? Carefully assess how much risk you are willing
to take.
