I don't think one needs more than a serving or two of it a week for good health

I believe you do not need meat at all to stay healthy and is often even tastier. Balanced vegetarian food provides everything the body needs. Though I have no problem with people eating meat once or twice a week. That would already be a improvement  healthwise for most people. Most people today eat more meat and proteins than the body can metabolise and discharge - thus in my opinion the reason for many chronic health problems.
