Since reading 'natural flavoring might contain castoreum (beaver's butt glands) I tend to read ingredients on everything I eat now.
I put a piece of gum into my mouth this afternoon not thinking of the ingredients-when I casually read the back of the gum box. It said 'natural flavoring' so I emailed the company asking if their products contained 'castoreum' in which the company responded, 'No' then I asked what the natural flavoring was and their response was:
"Unfortunately we can not tell you what the natural ingredients are in the products. It is proprietary information."
To me, as a consumer, I feel as if I have a right to know what I am consuming and putting into my body.
