Food aversions
When talking about foods you dislike, use the verb détester (to hate). Because it expresses a general preference, it is always followed by a definite article (le, la, l', les).
Saying "never"
To say you "never" do something, use the negative pair ne ... jamais. Just like ne ... pas (not), these two words wrap around the conjugated verb.
If you are talking about avoiding a type of food entirely, remember the negative article rule: indefinite and partitive articles (un, une, des, du, de la) change to de (or d' before a vowel) in negative sentences.
Dietary restrictions
The ne ... jamais + de structure is very useful for explaining allergies or dietary restrictions, such as following a vegan diet (un régime végétalien).
Definite articles in the negative
While un, une, des, du, and de la change to de, definite articles (le, la, l', les) never change in a negative sentence. Whether you are refusing to taste (goûter) a specific dish or avoiding a chore, keep the definite article.
