I am looking for some studies who compared the impact of plant based diet vs plant based diet with a little portion of organic animal products. (nutritionfacts.org)
These include foods such as sugar, grains, non organic animal products and alcohol, and also adding in healing foods such as live enzymes and probiotic foods. (zestforever.com)
So unless you are buying pastured - raised, certified organic animal products then you are still consuming the soy and grain second hand. (makingthymeforhealth.com)
