Sentence: Whole foods means food that's in its original form, straight from nature, typically whole fruits, veggies, whole grains, et cetera.
I want to know why "means" not "mean" is used here.
I assume "food" is a both uncountable and countable noun. The plural form of "food" is "foods". Plural subjects must have a plural verb. So when "foods" is subject, the verb must be plural, which is in accordance with the subject.
