If you only had the choice to eat conventionally raised meat, would you eat it or would you opt for a cheaper protein source such as beans.
Legumes have sustained many cultures for thousands of years, the Tarahumara Indians of Mexico live off a diet rich in beans and yet don't suffer from modern diseases, such as diabetes and heart disease. Legumes are a great source of fiber, minerals (not as bioavailable as meat), and protein, but they also have lectins, saponins, and a considerable amount of phytic acid.
Lectins
Lectins seem problematic, but the following two studies showed that cooking destroys most of it.

Phytic Acid
Personally I feel phytic acid is not much of a problem unless the diet has a low nutrient density, but a lot of it can be destroyed through soaking and fermentation.

Saponins
Not to sure how to get rid of these. Maybe by carefully washing them? Or skimming the foam that forms on top when you boil them?
Other potential problems
Storage?? read Melissa's article: http://huntgatherlove.com/content/storagepossible-neolithic-agent-disease
Any others that I might be missing???
Conventional Red Meat:
Is well...junk. Animals are mistreated, badly fed, injected with a ton of hormones and antibiotics, and most of the conventional meat you find in supermarkets is old and heavily painted to keep it looking new and fresh. There is ton of studies on the potentially harmful effects of conventionally raised meat, and it's potential effects on human health.
I am super poor right now, and my high intake of conventionally raised meat has been making me feel terrible. Right now I want what's best for my health. If you were to only have a choice between conventional meat and legumes what would you opt for?
