I suggest caution to anyone going vegan 100%. I know of cases where vegans ended up with cancer and/or death prematurely. Close to me had two co-workers die prematurely and one could say they were fanatic vegans. Another had her tongue removed because of cancer. She kept up with everything healthwise.She avoided meats altogether.
My father hardly ever ate veggies, didn't exercise, was overweight, ate lots of meats, (pork, etc), and still lived to a "normal" 82. He died of a stroke, due to high blood pressure, because he didn't keep up with medication. He outlived some of the vegans I know by decades of lifetime. He was still strong and active when he had the stroke. Perhaps, my Dad lived a normal life because he ate homemade meals, though he had bad practices.
Like others stated here, balance is the key. I like my wine with meals, love x-virgin olive oil, and I eat my veggies. My wife is a SDA, so she does not cook pork, so I eat pork less than before. I don't take any diets, because they are for me an irritation. I avoid sodas and try to eat homemade meals. I cannot emphasize that enough. HOMEMADE meals. Avoid anything processed, at least, keep it to a minimum. Just the basics. I don't follow warnings that I should not use salt, or eat eggs. No, I enjoy the salt moderately. I love eggs a few times a week. Nutritionists change their theories every few years, a few decades at most. So what they preach today as true nutrition may be wrong science 10 years from now. It reminds me of WT doctrines where they change at whim.
