Processed meat, alcohol, and tobacco all classified as type 1 carcinogen. Makes me laugh to see some of the responses. In the end, regardless of what we eat or what we do, we have no idea whether it will have an effect on our own longevity or quality of life. Anyone can be hit by a bus, have a congenital malformation or get a freak disease regardless of our habits. I see supposed environmentalists rave about their plant-based diet but flying to go on holidays a few times a year. How many times I've heard drinkers trying to justify their habit with the "good for the heart" study or the chocolate addict going on about the merits of chocolate. Carbs are bad, fats are bad, sugar is bad, GMO food is bad... Eat organic... Live in the countryside, less stress and pollution...What's the flavor this week?
Bottom line is that people should do what makes them feel good and happy, let other people be, and avoid lecturing others about what might or might not be best for them. Most of this is common sense and most things in moderation are not that likely to cause our demise. In the end, no one knows how and when they are going to die unless they do the job themselves.
