Sugar is one of the most commonly consumed substances in the world, yet many people fail to realize how much of it they’re actually consuming.

Food manufacturers often hide sugar in their products under different names, making it difficult for consumers to identify how much sugar they’re consuming, let alone avoid it. Here are four foods that are often loaded with hidden sugar:.

1. Yogurt

Yogurt is often marketed as a healthy food thanks to its probiotic content, but many brands are also high in sugar.

Some flavored yogurts can contain up to 20 grams of sugar per serving, more than a candy bar! Always read the label and stick to plain yogurt, which has naturally occurring sugar from lactose, and add your own fruit for flavor.

2. Granola Bars

Granola bars are typically marketed as a healthy snack, but many brands contain as much sugar as a candy bar. Some bars are loaded with high-fructose corn syrup, which is a cheap sweetener that can lead to insulin resistance and other health issues.

Instead, opt for granola bars made with whole food ingredients and sweetened with natural sweeteners like honey or dates.

3. Salad Dressing

Salad may seem like a healthy option, but if you’re drenching it in sugary salad dressing, you’re not doing yourself any favors.

Many bottled salad dressings contain added sugar, especially low-fat varieties that use sugar to compensate for the lack of flavor. Making your own dressing is easy and allows you to control the ingredients, so try making a simple vinaigrette with olive oil, balsamic vinegar, and Dijon mustard.

4. Tomato Sauce

Tomato sauce is a staple ingredient in many meals, but beware of the sugar content. Many brands of tomato sauce contain added sugar to balance out the acidity of the tomatoes. Some tomato sauces can contain up to 12 grams of sugar per half-cup serving.

Look for brands that have no added sugar or make your own sauce from scratch with fresh tomatoes.

Remember, sugar is often disguised as other ingredients, so always read the label and be aware of the many names sugar can take, including high-fructose corn syrup, agave nectar, cane sugar, and fruit juice concentrate.

Being mindful of hidden sugar can benefit your health in the long run and help reduce your risk of developing chronic diseases.
