Just to interrupt a bit with something not from the Bible.
Many long term studies have been done using 7th Day Adventists, who maintain a vegetarian diet, don't smoke or drink, and promote exercise.
They all show that these factors lower cancer risk by incredible amounts, and life span is lengthened.
I am not a 7th day Adventist, but I do try and eat the way they do. I call it my "God" diet, eating foods as close to the natural form that God made them. I also exercise regularly.
My husband eats what I cook him, but after gaining some weight from eating too many donuts at work, he became pre-diabetic. We went to a workshop on what to eat, to gain control over blood sugar, and it was almost the same as my diet. Meat was allowed, but only once a week for red meat, and fish once a week for Omega Oils.
His sugar levels have been back to normal for several years, since he whole heartedly embraced my diet.
Anyway, I do believe God created us to function in certain ways, and the North American diet is NOT it! I do believe God gave people the freedom to eat what they wanted after the flood, but until the 20th century, most people ate a plant based diet, and cancer was almost unknown.
People are killing themselves with bad lifestyle choices. I don't think God is happy.
Here is the link to the studies. I urge you to read it, and then think about what God wants you to eat. This is NOT about following Old Testament Levitical laws, but really thinking about what is healthy, and what pleases God, as we keep our bodies as a temple for the Holy Spirit. Not because of legalism, but because some lifestyle choices are closer to what God wants for us!

We are not to go back to the Old Testament laws, but maybe looking at Genesis before the flood is a better idea than anyone ever knew!
