Sorry, but don't know where you got your info from but cottage cheese is never and I mean never first choice. You need to go to the website I left you and read on the protocol and see that the Webmaster there will go into detail on how cottage cheese is not quark and yogurt is the closest thing. Store bought organic, is still high heated yogurt and is not the optimum way to go and quite expensive.
IN the end do what is best for you, but I am highly afraid you are being led astray. We are not here to convince you, just to offer help.
Read before you write and then you will know the real truth and if you had read my hundreds of post on this flax seed forum as I asked you again would not be asking these questions.
