I think what you are referring to Faeriegirl, is the post that you said you were having 8 oz. of cream a day. From that you were told that 8 oz may be way too much, but not that, cream is bad for you. Just don't use so much in one day. We all depend on cream, but maybe 2-3 oz a day, more than that, yes it may slow you down.
If you check the book, it may help you to understand this a bit better, somewhere it tells you how much you should have in a day, I think.
