Supermarket shelves are packed with different oils, but which ones are actually good for you?
超市货架上摆满了各种各样的食用油，但真的对你有好处的是哪些？
These are three big myths to look out for, according to Nita Forouhi, Professor of Population Health and Nutrition at Cambridge University.
我们需要注意三个错误的观点，这是尼塔·弗洛西教授的观点，她是人口健康与营养学教授，就职于剑桥大学。
Myth 1. Avoid using sunflower and vegetable oils
误区一、避免使用葵花籽油和其它植物油
Sunflower and vegetable oils are not unhealthy options.
葵花籽油和其它植物油并非不健康的选择。
In fact, they are low in saturated fat and high in polyunsaturated fats such as omega-3 and omega-6 which are essential for brain and heart health.
其实，这两种油中的饱和脂肪含量低，多不饱和脂肪含量高，比如欧米茄 3 和欧米茄 6，这些多不饱和脂肪对大脑和心脏健康十分重要。
Myth 2. Olive oil is always the best choice
误区二、橄榄油是最好的选择
Olive oil has a low smoke point – the temperature at which oils release toxic compounds.
橄榄油的烟点低，烟点是油开始释放有毒化合物的温度。
It's best saved for salads and other cold dishes. But for frying, use sunflower or vegetable oils instead.
橄榄油最好用在沙拉和其它凉菜中。在煎炒时，用葵花籽油或其它植物油。
Myth 3. Margarine and butter are unhealthy
误区三、人造黄油和黄油都不健康
Margarine sold today can help lower bad cholesterol due to its high level of unsaturated fat. Butter can also be enjoyed as part of a healthy diet, according to Professor Forouhi.
市场上出售的人造黄油能帮助降低有害胆固醇，这是因为人造黄油中不饱和脂肪的含量很高。黄油同样可以作为健康饮食的一部分被享用，弗洛西教授称。
But it's better to use oil when cooking, which has less saturated fat.
不过最好还是用食用油做饭，因为食用油中的饱和脂肪含量较低。
