"I now believe my health and that of my family depends on eating meat, raised and slaughtered as humanely as possible"

Does that mean eating only kosher or perhaps only kosher or halal meat?

I am not a strict vegetarian, although I typically eat fewer than 4 meat meals a month.

Aside from the health dangers of eating large amounts of meat, there are the issues of cruelty to animals, and the great wastefulness involved in raising animals for food. It typically takes around 16 pounds of grain to produce one pound of meat. Animals raised in the US for for food produce over 20 times the manure than the waste produced by the US population. Feeding grain to livestock animals greatly increases the demand for grain and keeps prices much higher than they could be. This is one reason for the high levels of starvation in some lesser developed countries. If everyone in the world would become a vegetarian, grain prices would be so much lower.
