What It Means: Contains less than 0.5 gram of trans fats per serving.

The Health Implications: Trans fats are associated with raising bad LDL cholesterol and lowering good HDL cholesterol, which increases a person’s risk of developing heart disease and having a stroke.

Keep in Mind: Trans fats are sometimes replaced with unhealthy saturated fats, like palm and coconut oils, which also aren’t ideal. What’s more, most foods with trans fats, such as cakes, cookies, and doughnuts, are high in calories and low in nutrients.

Bottom Line: Avoid any product with “hydrogenated” or “partially hydrogenated” in the ingredient list; these terms indicate the presence of trans fats. But keep in mind that you should limit saturated fats, too.

Tip: Do the math for trans fats. If one serving has, say, 0.4 gram and you eat four servings, the trans-fat count can add up.
