Diet & Exercise

Does anyone else think it's stupid that commercials for products that want to make tenuous links to being healthy always include "when taken as part of a balanced diet" or "as part of a regime of healthy diet and exercise"? I include products such as Nutella and slimming drinks in this spiel. Any health or slimming element would obviously come from the existing "balanced diet" or "regime of healthy diet and exercise" rather than the latched on product. I love my Nutella as much as anyone else but I'm hardly going to believe that any of its nutritious properties is the catalyst for improved health.
