Pointless Food Rituals

QUESTION: Today's comes from CC...
"I'm very committed to making sure our family eats healthy foods and gets lots of exercise, but my husband says I'm overdoing it. Does the Bible say anything about living a healthy lifestyle?".

IRRELIGIOUS PERSPECTIVE:
There's not going to be anyone who could argue against healthy foods and lots of exercise being a worthwhile guide. However, what exactly this means is not cut and dried. As we learn more about nutrition and how the body works we modify these guidelines. One of the key words in a healthy lifestyle is balance. Don't become too fanatical about diet. Eat a bit of everything and enjoy your repast without guilt.
The Bible lists animals that should be eaten and vice versa. However, these rules do not apply now as farming techniques have changed and our perceptions have changed. For example pigs were forbidden to be eaten because they were unclean animals, but this does not apply now. Don't deny yourself the luxury of eating bacon - it is one of life's pleasures! Some religions instruct their followers to eat unleavened bread at certain times. There is no nutritional reason for this. Outdated rules such as this prove the worthlessness of following an ancient text that was written for a time long gone. Most belief systems have pointless eating rules which serve no useful purpose: Don't eat certain foods; Eat particular foods on particular days; Kill animals in a certain way; etc.
