Recently, it is a common belief that small regular amounts of wine will have various positive health effects such as the prevention of heart diseases, cancer or strokes. Citizens of those parts of Europe with a distinct vinic culture have potentially longer lifes (the so-called French paradox).
At the same time, many claim that wine induces the exact opposite effects. There is a lot of confusion since even national health organizations have claimed very different recommendations concerning its health impacts. While it seems to have some beneficial effects, it definitely contains a dangerous toxic substance which potentially damages cells: Alcohol.
