Polyunsaturated describes fats and oils that come mainly from plants — sunflower, soya, corn, many seed oils — and that food advice has long called better for the heart than saturated fat from animals. You will see polyunsaturated fat, polyunsaturated oil, polyunsaturated fatty acids (sometimes written PUFA). Omega-3 and omega-6 oils sit in this family.

Polyunsaturated多元不飽和的（polyunsaturated） describes fats and oils that come mainly from plants形容的是主要來自植物的油脂——sunflower, soya, corn, many seed oils像葵花油、黃豆油、玉米油，還有很多種籽油——and that food advice has long called better for the heart than saturated fat from animals飲食建議長期以來都說這種油比動物來的飽和脂肪對心臟更好。You你 will see polyunsaturated fat, polyunsaturated oil, polyunsaturated fatty acids會看到 polyunsaturated fat（多元不飽和脂肪）、polyunsaturated oil（多元不飽和油）、polyunsaturated fatty acids（多元不飽和脂肪酸）(sometimes written PUFA)（有時候縮寫成 PUFA）。Omega-3 and omega-6 oils Omega-3 和 Omega-6 這兩種油 sit in this family都屬於這個家族。

It is a nutrition-label and doctor-leaflet adjective, a bit formal, very common on bottles and boxes. Next to it on the same label you often get saturated (the “full,” often animal kind) and monounsaturated (olive oil is the famous one: one “not-full” place, not many).

It它 is a nutrition-label and doctor-leaflet adjective是營養標示和醫生衛教單張上會用的形容詞，a bit formal帶點正式，very common on bottles and boxes在瓶罐和包裝盒上很常見。Next to it on the same label在同一張標示上，緊接在它旁邊 you often get saturated常常會看到 saturated（the "full," often animal kind）（「飽和」，通常是動物性的那種）and monounsaturated還有 monounsaturated（olive oil is the famous one橄欖油是最有名的例子: one "not-full" place, not many只少一個地方「不飽和」，不是很多個地方）。

Though actually, “better than butter” was a loud, simple story, and researchers still fight about how simple it should be. For a student, the useful picture is: this word flags a plant-oil kind of fat, not a plastic, and not “all vegetables are healthy.” Deep-fried food can still be polyunsaturated and still be a poor everyday choice.

Though actually不過其實，'better than butter' was a loud, simple story「比奶油好」曾經是一個講得很大聲、很簡單的說法，and researchers still fight about how simple it should be而研究者到現在還在爭論這說法該有多簡化。For a student對學生來說，the useful picture is有用的理解是：this word flags a plant-oil kind of fat這個字標示的是植物油那一類的脂肪，not a plastic不是塑膠，and not "all vegetables are healthy."也不是「所有蔬菜都健康」的意思。Deep-fried food炸過的食物 can still be polyunsaturated還是可以是 polyunsaturated 的 and still be a poor everyday choice同時還是不好的日常選擇。
