I would limit the amount of non pastured meat. It simply is not the same. Get more of your calories from eggs, dairy and plant foods. Sardines and shellfish would be a good addition as well. Im of the camp that one should save their money and buy only the best animal products.
Also i dont know your finances but unless you are very poor, there should be enough money to buy organic/pastured. Food should be a priority in life, you only get one body.
