8. Gluten-free foods
Unless you have been legitimately diagnosed with celiac disease or gluten intolerance, there is no reason to buy gluten free foods. They are not necessarily even healthier than standard fare, as they still contain artificial ingredients and a ton of sugar to make up for the missing gluten.
You’ll also be forgoing necessary dietary fiber and the vitamins that fortify many regular products, so an effort must be made to compensate for that. To top it off, you’ll be spending twice as much on a gluten-free version of something. It’s not a smart choice unless you actually need to forgo gluten for your health.
