6. Fruit juice
As a child, you probably had a juice box tossed into your lunch each day and called it fruit. But even as an adult you may fall into the trap of thinking that juice is as healthy as fruit. It’s not. When juice is extracted from fruit, all the beneficial fiber is left behind. Fiber helps moderate the rate at which sugar is dumped into your bloodstream, so pure juice is going to hit you all at once.
Most commercial juices have added sugar, way beyond what is present in the fruit itself. They are also often pasteurized, which means that any heat-sensitive nutrients are destroyed before the product even hits store shelves.
