While reading this article from Bangkok Post.com, I noticed the word "juice" and its plural form "juices" are both used.
Consumers have long regarded fruit juice as a healthy option, especially when compared to carbonated soft drinks. But many credible scientific studies have found that drinking fruit juice is not the same as consuming fruit, because some commercial fruit juice products contain as much sugar as soft drinks, sometimes even more.
Such findings have been bad news for producers of mass-market fruit juices, as consumers are now looking for healthier alternatives.
... Many of these writers have noted the misconceptions about the health benefits of fruit juices and warned about high sugar content in some brands.
It isn't difficult to guess from the context that the "fruit juices" probably refers to fruit juice products, but if that is the case, I thought the writer should have written so.
1. Juice is the liquid that can be obtained from a fruit.
2. The juices of a piece of meat are the liquid that comes out of it when you cook it.
1. the liquid that comes out of a piece of meat when it is cooked
2. the liquid that occurs naturally in or is secreted by plant or animal tissue
I wonder which one of the four definitions above is applicable to the "juices" described in the article.
