food 可数和不可数都有。Food 有两种用法：作为不可数名词或可数名词。1. 作为不可数名词时，表示“食物”、“食品”，是用来指代一种广泛的概念，不可用数词（如 a/an, one, two 等）进行修饰。比如：- I enjoy eating Indian food.
- We should always have enough food in the house.
- Fast food is not good for your health.2. 作为可数名词时，表示“一种食物”、“一餐”，可用数词进行修饰。比如：- I ordered three different foods at the restaurant.
- There are many delicious foods at the buffet.
- She likes to try new foods when she travels.因此，food 既可以是不可数名词，也可以是可数名词，具体取决于句子的语境和用法。
