When it comes to our health, many of us rely on packaged foods, diet plans, and health gimmicks to stay slim and fit. But the truth is that not all foods that are marketed as healthy or low-fat are actually good for us.

In fact, some of these foods can pack in more calories, fat, sugar, and salt than their less-healthy counterparts. In this article, we’ll take a look at some foods that seem healthy but are secretly fattening, and what to look out for when you’re trying to make healthy choices.

1. Granola

Granola is often touted as a healthy breakfast food that is high in fiber and low in fat. But the truth is that many commercial granola brands are loaded with sugar and calories.

Some granola brands can contain up to 500 calories per cup, and as much as 30 grams of sugar. If you’re shopping for granola, look for brands that are low in sugar and high in fiber. Or better yet, make your own granola at home using whole grains, nuts, and dried fruit.

2. Dried Fruit

Dried fruit is a healthy snack alternative to candy, right? Not always. Many commercial brands of dried fruit contain added sugar, preservatives, and sulfites that can contribute to weight gain and other health problems.

Some dried fruit can also be high in calories and easily overeaten. Be sure to read the labels on dried fruit and look for brands that are low in added sugar and sulfites. A better alternative to dried fruit is to eat fresh fruit or slice your own dried fruit at home without added sugars.

3. Smoothies

Smoothies can be a healthy and refreshing way to start the day. But many commercial smoothies are loaded with sugar and calories, especially those that are made with fruit juice and sweetened yogurt.

A large smoothie at your favorite juice bar can contain more than 500 calories and as much as 30 grams of sugar. To make a healthy smoothie, use fresh or frozen fruit, plain yogurt or nut milk, and add some greens like spinach or kale for a nutrient boost. Avoid adding sweeteners, and limit the amount of fruit juice you use.

4. Flavored Yogurt

Yogurt is often marketed as a healthy food that is high in calcium and protein. But most commercial brands of flavored yogurt are high in sugar and can contain as much as 25 grams of sugar per serving.

Opt for plain yogurt and add your own fruit or sweeteners like honey or agave nectar. Alternatively, try Greek yogurt, which is higher in protein and lower in sugar than regular yogurt.

5. Veggie Chips

Vegetable chips are a popular snack alternative to potato chips. But many brands of veggie chips are fried and loaded with salt, oil, and calories. A serving of some brands of veggie chips can contain as much as 150 calories and 7 grams of fat.

A better alternative to veggie chips is to snack on fresh vegetables or make your own healthy chips at home using thinly sliced vegetables that are baked rather than fried.

6. Smoothie Bowls

Smoothie bowls are a trendy breakfast or snack alternative to regular smoothies. They are often made with fruit, yogurt, and granola, and topped with nuts and seeds.

But smoothie bowls can pack in more calories and sugar than a regular smoothie, especially if they are loaded with granola or other high-calorie toppings. To make a healthy smoothie bowl, stick to small portions, use fresh or frozen fruit, and top your bowl with seeds, nuts, or a small amount of granola for crunch.

7. Energy Bars

Energy bars are often marketed as a healthy snack or meal replacement that is high in protein and fiber. But many commercial energy bars are loaded with sugar, calories, and processed ingredients.

Some energy bars can contain as much as 300 calories and 20 grams of sugar per serving. Instead of relying on energy bars, try making your own healthy snacks at home using whole grains, nuts, and dried fruit. Or opt for a small serving of fresh fruit or vegetables instead.

8. Trail Mix

Trail mix is often marketed as a healthy and filling snack for hikers and outdoor enthusiasts. But many commercial brands of trail mix are loaded with sugar, salt, and oil, and can contain as much as 200 calories per serving.

Be sure to read the labels on trail mix and look for brands that are low in added sugar and salt. A better alternative to trail mix is to make your own mix at home using unsalted nuts, seeds, and dried fruit.

9. Frozen Yogurt

Frozen yogurt is often marketed as a healthier alternative to ice cream. But most commercial brands of frozen yogurt are high in sugar and can contain as much as 30 grams of sugar per serving.

If you’re craving a frozen treat, opt for a small serving of real ice cream or make your own healthy frozen yogurt at home using plain yogurt, fresh fruit, and honey or agave nectar as a sweetener.

10. Granola Bars

Granola bars are a popular snack alternative to candy bars and cookies. But many commercial granola bars are loaded with sugar, salt, and artificial ingredients, and can contain as much as 300 calories and 15 grams of sugar per bar.

Be sure to look for brands that are low in sugar and high in fiber, or make your own granola bars at home using whole grains, nuts, and dried fruit.
