When the magician duo Penn and Teller use their remarkable talent for misdirection — distracting you from what is happening right before your eyes — you fall for it time after time.

That just shows it’s pretty easy to fool yourself, even if you think you're being vigilant.

It’s the same kind of trick some juice companies rely on to get you to buy their beverages. According to a study in AJPH, a publication of the American Public Health Association, an analysis of top-selling "juice drinks," marketed to kids found that 97% showed images of fruits on the label, but only 47% contained any of the fruits that were depicted — and 37% contained none of the fruits pictured on their labels.

This has become such a problem that rather than changing the law, the Food and Drug Administration issued a recommendation in 2016 that says you should look at the ingredients list on a juice bottle to determine if a drink contains real fruit — the pictures (and words) on the label don't have to make it clear.

That's also true for many flavorings. For example, the FDA says current regulations allow use of terms like "maple" or "maple-flavored" on the food label without having maple syrup in the product, as long as it contains something that creates a maple taste.

We say skip juices and opt to give your child fresh fruit instead. Real fruit delivers fiber and an array of nutrients along with no added sugar or artificial sweeteners.

Then give thirsty kids water in BPA- and BPS-free bottles.
