"I love food and drink."
"We would like to invite you to our house for drinks."
"Foods that are rich sources of folate include spinach and other dark, leafy vegetables.'
So, when we mean that we love to eat and drink we just use those words as they are "food and drink," even though the understanding is clearly that we don't love only one item of food or one kind of drink.
When we mean more than one drink, we use the plural "drinks."
We also use "foods," and "drinks," as collective nouns - as per the above example about folate. We could just as easily say:
"Sugary drinks are bad for your teeth."
