If a food is classified as “low fat”, is it safe to assume that it is low calorie?
Absolutely not. There are plenty of food offerings like processed cookies, cakes, chips and pretzels that boldly advertise “low fat” but that are high calorie food products, per serving. That low fat claim can also lull you into believing that these foods are healthy or healthier products. Also not necessarily true, since manufacturers naturally replace the fat removed with either salt or sugar.
You do need to really examine a nutrition label and then the actual ingredients in order to fully assess a food’s “health value.”
