Most of us growing up fought with our parents over finishing or even eating the vegetables on our plates at dinner. Mom would tell us to eat them, because they are good for you. Sure they are, but like you I didn't want to eat them either. I remember my mother conning me into getting my spinach down, she would tell me that if I wanted to be strong like Popeye I had to eat my spinach, so I would hold my nose and swallow that disgusting canned spinach.
Well it seems that my mom was right, but not even she knew how right she was. A recent Harvard study, albeit a study that has not been peer reviewed yet claims that as many as one in three people who have had their lives cut short could have prevented it if they only had given up the meat in their diet.
About a year ago my wife and I started on a plant based diet.I did a lot of research before giving up my precious hamburgers, so I already new that this way was the best way to eat. All one has to do is look at the sickness rates of large groups that eat this way. Pre-KFC Okinawan's and Seventh day Adventists historically live longer than everyone else and have fewer diseases like cardiovascular, blood pressure issues and diabetes in my opinion anyways because, they ate beautiful fresh fruits and vegetables as their primary food source. As I understand it sweet potatoes are a major part of the Okinawan diet.
The study suggests that roughly 30 million deaths every year worldwide are "preventable" – those caused by things we can do something about, such as obesity, smoking and poor diet. One of the research team Walter WIllett says "That's not even talking about physical activity or not smoking, and that's all deaths, not just cancer deaths. That's probably an underestimate as well as that doesn't take into account the fact that obesity is important and we control for obesity."
If I am reading his quote correctly, he is basically saying that one in three people will live longer even if they smoke because they are eating healthier. They would expect that the 30 million number is low if the other factors are taken into account. Did you know that Hispanics live 8% longer on average than white or blacks? Studies suggest the reason is because they eat so many beans.
We could turn this article into a book, so I will stop here and suggest that you do your own research and make a decision about eating healthier. I highly recommend Dr Michael Gregor's website https://nutritionfacts.org/ and his book "How not to DIe"
