why is vegetable good to us?

It is because vegetable contains various nutritions, especially vitaminC and fibre, which can enhance our resistance against diseases and gastrointestinal health.

上面Suyi Lui Lui 話: Vegetables contact variety of nutrition, 但係contact只有接觸或聯繫的意思, 並冇包含的意思, 所以要用contain, 唔係contact.同埋我發覺自己ge回答有D grammatical mistake, 應該用contain, 唔需要s, 而nutrition係uncountable, 所以唔應該有s.
