Are Fat-Free Foods Good for You?

So now that we’re all on the same page that fat isn’t Satan, the devil or just plain bad, let’s talk about foods without fat—those health foods marketed as being fat-free.

What Are fat-free foods?

Some foods are naturally low in fat. Fruit, dark leafy greens, starchy veggies (potatoes, squash, corn, peas), and whole grains all contain no, or minimal, fat. But they also aren’t parading their natural fat-free state around the farmer’s market. When you see the label “fat-free” it’s almost always on a packaged food, somewhere in the grocery store—in the cereal, bread, milk, frozen food, chips, crackers, AND salad dressing aisle. In order to get that shiny “fat-free” label, a food must have less than 0.5 grams of total fat.US Food and Drug Administration. (2013). Guidance for Industry: A Food Labeling Guide (9. Appendix A: Definitions of Nutrient Content Claims). Accessed on 9/1/15 from: http://www.fda.gov/Food/GuidanceRegulation/GuidanceDocumentsRegulatoryInformation/LabelingNutrition/ucm064911.htm

To be labeled as “low-fat” it must have less than 3 grams of total fat. Now you might be thinking, “Well, that doesn’t seem so bad—it just means that there’s no fat in a food”.

Fair enough, and this is when you need to dive a little deeper.

Why Fat-Free Foods Can be Bad

Say that label is on a rice cake. Rice cakes are basically just puffed rice, so it makes sense that they have no fat in them. But say you see that label on a salad dressing, a pudding, a cookie, a cracker, a cake, or a nutrition bar. If you were to make any of these foods at home, you’d probably add some oil, butter, nuts, or seeds—all sources of fat.  In order to replace the fat in those foods, food manufacturers have to add something else. And that something is usually sugar.

To replace the mouthfeel, texture and taste of fat, food scientists use flour, salt, emulsifiers and texturizers. When you replace the fat in a food with sugar, you reduce the satiety factor—how full and satisfied you’ll feel after eating it.   Sugar has the opposite effect on your blood sugar that fat does—sugar spikes your blood sugar, and ends in a crash, leaving you with even lower energy and hungry as ever. Replacing fat with other ingredients often results in a less appealing product—both in taste and appearance. And if it’s not satisfying, you’re likely to eat more of it.

Fat-free foods to watch out for:

  • Salad Dressing
  • Crackers
  • Chips
  • Pasta Sauce
  • Pudding
  • Cookies
  • Cakes
  • Yogurt
  • Peanut Butter
  • Nutrition Bars

Things to check before buying fat-free foods:

  • How many grams of sugar per serving? Is it higher than most other products of the same kind? (Chips vs chips, crackers vs crackers).
  • Compared to the regular version, which one has:
    • More recognizable ingredients?
    • More sugar?
    • More calories?
    • A more reasonable serving size

If your goal is to lose weight or improve your health, don’t assume that a fat-free food is naturally good for you. Stock up on whole foods, and when choosing a packaged food, choose those with healthy fats—not fat-free. Try to avoid the worst weight loss tips we’ve heard and remember to focus on eating balanced meals.
