It's just such a nuanced topic people have a really hard time reasoning about it. For example, Drinking Alcohol every day clearly increases your chances of developing disease.

Drinking zero Alcohol actually decreases the likely hood of you living to a ripe old age.

Is it that Alcohol is healthy in small doses? Probably not. Perhaps people who drink a glass of wine once or twice a month have a less stressful life than someone who never drinks.

That's why nutrition studies are so hard to be done right. You have to literally watch them consume it and you need a control group and it needs to take place over years.

There are books written about Bluezones that say eating meat shortens your life yet HongKong has the both the highest life expectancy and the highest per person meat consumption in the world.

You really have to take every single claim and study with a big giant grain of salt and a whole lot of skepticism.
