"I love candy."
Translation:אני אוהב ממתקים!
We use collective nouns in English. So while it would literally be "candies", you'd usually still use candy. Examples: Did you get enough candy for all the kids? How much candy did you get? You bought too much candy.
You see this a lot in English with food items. I got enough fish for five people. How much fruit is left? (Only 10 bananas).
