Me and one of my friends had a sugarcane juice in our nearby shop.
there we saw a board that listed the benefits of sugarcane juice.
the sentence that caught attention was this.
"This is a refreshing, sweet and a wonderful substitute for an aerated drink. This benefits the body from gaining unnecessary calories."
The sentence in question was the second one.
"This benefits the body from gaining unnecessary calories".
My opinion was that this sentence is correct and it conveys the meaning that drinking sugarcane juice instead of an aerated drink, results in less calories.
My friends opinion was that this sentence is wrong and the usage of from is wrong (he agreed on the meaning but he felt this sentence conveys the opposite)
According to him,to get the meaning that i and shopkeeper thought, the correct formation of the second sentence should be
"this benefits the body from losing unnecessary calories.."
"this benefits the body from gaining necessary calories.."
Is it correct? we are not native speakers. can you tell as which one conveys the meaning we thought and is correct and explain why?
Can you also point us to the usage of "from"
