(HealthDayNews) -- Power bars and energy drinks may make handy snacks but they are often less nutritious than they purport to be, says The Johns Hopkins Hospital.
While they're fortified with vitamins and minerals, power bars are also loaded with calories. According to recent studies by consumerlab.com, the labels on 65 percent of energy bars claimed they contained less carbohydrates, fat and sodium than they actually did.
And sports drinks sometimes contain ingredients that haven't been approved by the US Food and Drug Administration, such as gingko biloba and echinacea.
As an alternative for a quick snack, try regular water, fresh fruit and other whole foods.
