The Importance of Randomized Controlled Trials

A lot of the research we've had so far that's evaluating health response to grass fed versus grain fed meat has been observational in nature. So randomized controlled trials can be helpful because they can take another step in eliminating confounders and give us more reliable data. We are doing a study at least a very acute study right now. The Green Acres Foundation is studying how plant foods, animal source foods interact with mineral agriculture. And other studies look at if you eat the same foods and match for protein, for carbohydrates, for fat, for calories.
