用法筆記

Uncountable — do not say 'a cholesterol' or 'cholesterols'. Frequently paired with adjectives 'high' and 'low' to indicate risk level. 'Bad cholesterol' refers to LDL (low-density lipoprotein) and 'good cholesterol' refers to HDL (high-density lipoprotein); these are everyday rather than clinical terms.

常見錯誤

❌I have too many cholesterols in my body.
✅I have too much cholesterol in my body.
💡cholesterol is an uncountable noun and cannot be pluralised.
❌Eating fat gives you cholesterol.
✅Eating foods high in saturated fat can raise your cholesterol levels.
💡dietary fat and cholesterol are related but not the same thing; the body also produces cholesterol on its own.
