It’s not always apparent when foods we love have zero nutrition. These 13 favorites are filled with sugar, fat, and empty calories—and some may surprise you.

A ton of research suggests limiting sugar-sweetened beverages, which are pretty much the ultimate example of zero nutrition. In fact U.S. Dietary Guidelines suggest there’s strong evidence these beverages contribute to excess weight in adults and children. Surprisingly, some choices in this category are better than others. Ginger ale has 32 grams of sugar per can versus 49 grams in the same amount of cream soda, according to the USDA Food Database.

Amy Gorin, MS, RDN, owner of Amy Gorin Nutrition, recommends ditching low-fat versions of the nutty spread. “Peanut butter offers fats that are filling and heart healthy. But when that fat is removed or reduced, extra sugar and other filler ingredients are often added. When you’re shopping for peanut butter, read the ingredients label and pick one that contains only roasted peanuts.”

Gorin says “margarine has been considered a healthy alternative to butter, but many versions contain partially hydrogenated oil—an ingredient that contains trans fats, which are harmful. They can heighten your “bad” LDL cholesterol, decrease your beneficial HDL cholesterol, and heighten your risk of heart disease.” Instead of margarine, consider using a small amount of a heart-healthy oil, such as extra-virgin olive oil. But be mindful of cooking with oil at high temperatures.

Fresh fruit is an important component of a healthy diet, but how it’s prepared matters. “You might think that canned fruit is as healthy as fresh, but if the label shows that it’s canned in “light syrup” or “heavy syrup,” it means that the fruit has sugar added to it,” Gorin says. “You want to limit the added sugar that you eat.” She suggests reading your food’s ingredients label to make sure it contains nothing but fruit. “Fruit canned in juice or water is usually a safe option,” Gorin adds.

When summer rolls around, ice pops and fruit-flavored shaved ice may seem like a healthy, refreshing treat. But one quick glance at the ingredients might change your mind. Most are made of sugar, sugar, and more sugar with artificial flavors, preservatives, and colors. We already know added sugar is a problem, but an article in the Journal Neurotherapeutics suggests artificial colors are also a public health problem and have been linked with behavioral issues in children. Choose pops that are made primarily with juice, so that you’re getting some nutrition for your calories

According to the USDA Food Database, cotton candy is 100 percent sugar. A one-ounce serving averages 110 calories and 28 grams sugar. This melt-in-your-mouth treat may seem “light” but it isn’t, and the effect on your teeth isn’t pretty either. The most recent available World Health Organization guidelines recommend added sugar make up no more than 10 percent of calories to reduce incidence of cavities and gum disease. That’s equivalent to about 38 grams of sugar for someone eating 1,500 calories a day. Given this, a single ounce of cotton candy contributes 73 percent of the recommended daily limit. Gum disease can be a sign of a more serious health condition; here are 7 signs of disease your teeth can reveal.

That creamy delicious chocolate topping on your cake clocks in at around 140 calories with 18 to 19 grams of added sugar and about 2 grams of saturated fat in just 2 tablespoons, according to the US Food Database. You’ll find a host of other questionable ingredients including hydrogenated fats, a source of trans fat that are bad for your heart, according to the American Heart Association. At less than 0.5 grams per serving, trans fat doesn’t have to be declared on a label according to the FDA, so you won’t know it’s there—and let’s face it, you’re likely to eat more than two spoonfuls. Go for light whipped cream instead. It’s literally half the calories.

NYC-based dietitian Natalie Rizzo, MS, RD, says some of the emptiest calories you can take in are found in sugary blended coffee drinks, like frappuccinos or caramel macchiatos. “To me, these drinks masquerade as a caffeine pick-me-up, but are more like a dessert. I absolutely think it’s OK to indulge occasionally but making these your go-to drink at the coffee shop is definitely not a good choice,” she says. “Sugar-sweetened coffee drinks can have more sugar, fat, and calories than most meals!”

Your standard slice of white bread has little nutrition. According to the USDA Food Database, a slice has about 150 calories and is lower in fiber due to stripped down whole grain. White bread has a laundry list of ingredients, many of which are unrecognizable to the average consumer. Two ingredients you know to avoid, however: high fructose corn syrup and added sugar, both of which have been linked to increased incidence of diabetes, according to the Journal Global Public Health. Use these smart swaps to eat more healthy carbs.

All the health benefits related to chocolate don’t apply here. Primarily made up of cocoa butter, milk, or cream, flavors and emulsifying agents, as indicated in the FDA Code of Federal Regulations, white chocolate has around 150 calories, 5 grams saturated fat, and 16.5 grams of sugar per ounce according to the USDA Food Database. Unlike dark and milk chocolate, which contain varying amounts of the more antioxidant-rich cocoa, white chocolate contains zero cocoa. Choose dark chocolate for greater nutritional benefits, according to an article in the Journal Antioxidant and Redox.

A saturated-fat-and-salt bomb, 4 ounces of raw salt pork has 33 grams of saturated fat and over 3,000 milligrams of sodium, according to the USDA Food Database. Thankfully it is mainly used in relatively small amounts as a flavor enhancer in cooking, for example in baked beans or collard greens in traditional Southern cooking. Still, it’s best not to make salt pork a daily habit.

“Flashy packaging and celebrity endorsements draw adolescents and young adults to energy drinks,” says Toby Amidor, MS, RD, Wall Street Journal bestselling author of The Easy 5-Ingredient Healthy Cookbook. Amidor cautions that “energy drinks are sold as a dietary supplement, which means they aren’t subject to the same safety standards as foods and drinks.” What’s more, they contain ingredients such as caffeine—which can increase heart rate, trigger anxiety, and lead to upset stomach—and Guarana, a caffeine-like stimulant.

This dish is a favorite among restaurant food trends, according to food delivery giant GrubHub, reports NBC News. Well, fans of the dish may want to take a closer look at what they’re eating. An average order as listed in USDA Food Database delivers over 1,500 calories, 87 grams of fat (of which around 15 grams are saturated fat), 62 grams of sugar, and a day’s worth of sodium at 2,327 milligrams. Because it contains the three main nutrients the US Dietary Guidelines consider health risks, this is a dish worth skipping. Here are the healthiest Chinese take-out options.
