Does your mouth water when you think of cookies, burgers and French fries? Many people prefer junk food like this to healthy food because they develop a taste for it. Processed, baked, and fried foods often contain a high amount of trans fats.

Trans fats raise bad cholesterol (胆固醇) and lower the good cholesterol that your body needs. Fatty foods do more than cause people to gain too much weight. Trans fats build up in the body and block blood flow to the heart. People whose diet contains a high percentage of trans fats are at risk of developing heart disease or having a stroke.

Food companies and restaurants choose to use trans fat oils because they’re cheap and they make food like crackers and baked goods last longer. They also improve the taste of food. Trans fats became very popular in the second half of the 20th century. This is around the time butter got a bad name for its cholesterol levels. People were told to use margarine (人造黄油) containing trans fats instead because it was “healthier”, but we now know that butter is actually the healthier option.

We all need some fat in our diet. There are three different types of fats: saturated (饱和的) fats, unsaturated fats and trans fats. Doctors recommend that we get most of our fatty calories from unsaturated fats. Neither butter nor margarine fit this category, though other spreads like peanut butter do. Reading the list of ingredients on the label is a good way of avoiding dangerous ingredients like trans fats. Another way is to avoid eating out, especially in fast food restaurants. Also, when shopping try to buy the majority of your food in the fresh-food section and limit the amount of processed and packaged food you buy. You might not think this is important if you’re young, but the choices you make now will affect you for the rest of your life.
