I've just finished reading a book called What the Bible Says About Healthy Living, by Rex Russell, M.D.
It gives three biblical principles that, if followed, can make you much healthier.
Here are the book's three principles:
Principle I: Eat only substances God created for food. Avoid what is not designed for food.
Principle II: As much as possible, eat foods as they were created - before they are changed or converted into something humans think might be better.
Principle III: Avoid food addictions. Don't let any food or drink become your god. (from page 29)
To follow principle #1, try to avoid animals designated "unclean" (including pork, shellfish and others).
They were designed for purposes such as being cleaners.
As to following principle #2, try to avoid eating genetically modified foods, processed foods, etc.
For the third, the author recommends periodic fasting. Does it strike you as slightly odd that some Christian denominations or groups condemn drunkenness but neglect to mention gluttony, which is also a sin?
