Sources:
impact of alcohol on the body and brain is complex and extensive. Here are some key insights from on the :Alcohol's Effects on the Body and Brain
- General Impact: Alcohol affects individual cells, organs, and the brain. It alters thinking and behavior and has both acute and chronic impacts on health. 1
- Cellular Damage: Alcohol is both water- and fat-soluble, allowing it to penetrate cells easily, which explains its widespread damaging effects. Ethanol, the type of alcohol fit for consumption, is toxic and needs to be converted into acetaldehyde, a substance even more harmful than ethanol. 2 1
Hormonal Effects
- Hormones: Alcohol increases the conversion of testosterone to estrogen due to the aromatase enzyme. This effect can lead to higher estrogen levels in both men and women, affecting libido, fat storage, and increasing the risk of estrogen-related cancers. 3
Cancer Risk
- Cancer: Alcohol consumption is linked to an increased risk of various cancers, particularly breast cancer. It affects gene expression and cell cycles, promoting tumor growth and impairing the immune system's ability to combat cancers. 4
- No Safe Dose: Research suggests there is no safe dose of ethanol, with even low to moderate intake increasing health risks. 5
Miscellaneous
- Positive and Negative Effects: While there are minimal documented benefits to alcohol consumption, such as occasional cardiovascular benefits seen in some studies, the negative impacts are significant. Regular consumption can disrupt gut health, increase stress levels, and lead to other health issues. 6
Recommendations
- Zero to Low Intake: The best health outcomes are associated with zero alcohol consumption. Low to moderate consumption may still carry risks, but strategies can help mitigate some negative effects. 7
These insights suggest a cautious approach to alcohol consumption, emphasizing awareness of its diverse and significant impacts on health.
