Hi. I hope you could help me. I don't understand the meaning of the following sentence.
> A 90 day feeding study of Emulsifier YN at dietary levels up to 6% in rats showed no adverse effect on growth
"at dietary levels up to 6% in rats" Does this mean giving the rats food containing Emulsifier YN up to 6% of their weights? or 6% of the food weights?
Top answer
I read it as up to a maximum of 6% of the content of the food. (It might be by weight or volume, it's not clear)
