You're in a rush on the way to the work or can't stop for a meal post-workout. Maybe you haven't had enough protein by the end of the day so you reach for one of those processed protein bars — the type that claims it has zero to few net grams of carbs and packs a whole 20 grams of protein. "A good protein bar is only as effective as its ingredients," Dr. Luiza Petre, board-certified cardiologist and weight-management specialist, tells POPSUGAR. "Do not just read the front wrapper; delve into the actual composition of ingredients on the back." Once you do that, Dr. Petre says you'll find it common to see tons of harmful ingredients like partially hydrogenated oils, food coloring, high-fructose corn syrup, sugar alcohols, and artificial sweeteners.
A good rule of thumb is if you don't recognize the ingredient, don't put it inside of you.
