7. Alcohol
We regret to inform you that alcohol has no health benefits, despite the fact that many people will disagree. It has a very high caloric content, and consuming it might result in dehydration, liver damage, weight gain, depression, and skin issues. Not to mention the unwise decisions you make when intoxicated. So, believe the marketing and drink alcohol every day if you want to harm every system in your body, including the liver, brain, and skin. Avoid it if not.
