You are correct that Satan is behind sickness.All one has to do is read the bible.The thief{Satan}has come to kill,steal and destroy.
But Jesus came that we might have life and have it more abundantly.Before the fall it was fruit,nuts and veges.Eating meat came after the fall.Read Genesis 3:21!God clothed them in skins.We do have to take care of our bodies for they are the temple of God.
But we are only to be obsessed with God!Satan,with our help,has perverted our foods.For an example,God gave us the poppy for pain{knowing we would fall}but it has been perverted into drugs.You are right on track in my opinion.But I found this site looking for alternitive medicine but take what I feel comfortable about and leave the extreme to others.To each his own.There is good info and caring pp here.Love,Dot.
