Don’t be fooled into thinking these foods are healthy.

Grocery store shelves are lined with foods promising all kinds of health perks. “Low in fat,” “low in sodium,” “no high fructose corn syrup,” or “excellent source of vitamins and minerals” are just a few gimmicks used by the food industry to make you believe a food is healthy. People who don’t know any better are deceived by the advertising found on packaging and are led to eat empty calories, too many calories, or the wrong kinds of calories.

A big part of losing weight and getting healthy is learning the difference between what’s healthy and what’s not. Once you have this information, you can choose wisely. Here are a few foods that are frequently mistaken for being good for you.

Instant Oatmeal

Isn’t oatmeal one of the healthiest options for breakfast? Yes, when you’re eating regular-rolled or steel-cut oats with minimal sweeteners added. But many of the flavored instant oatmeal options contain added sugar and sodium and lack fiber and protein. A bowl of these refined carbs will leave your stomach growling long before lunchtime. Make your own oatmeal or look for an instant variety with a primary ingredient of whole oats or steel cut oats. You’ll also want oatmeal without sugar on the ingredient list or near the end and go for oatmeal that contains a minimum of five grams of protein and four grams of fiber per serving.
