• The first myth: Eating margarine is bad for your heart. That used to be true, when it was loaded with trans fats and hydrogenated fats that raised the level of bad cholesterol in your body. These days, margarine is made with healthy polyunsaturated and monounsaturated fats. It's actually healthier than butter. Here's another myth: White meat is lower in fat than red meat. That's not necessarily true! Nutritionist Angela Dowden says butchers used to leave more fat on cuts of red meat. Now, a lean sirloin steak may have only five grams per fat while chicken thighs could have nine! How about this myth: If you're dieting, eat a lot of small portions throughout the day or what's called "grazing." Dowden says that's one way to control hunger, but by eating more often, you often eat more calories! Stick to a three-meal-a-day plan. One final myth about foods: Fruits and veggies need to be refrigerated! *That's not always true. Scientists in Oklahoma found that watermelon left at room temperature for two weeks was packed with more antioxidants than one stored in the fridge!
