PROBLEM: Juice from the Grocery Store
The juice you buy from the grocery store isn’t always as healthy as it seems. Often, those bottles and jugs actually contain a “juice cocktail” or “juice drink” which is loaded with sugar, high fructose corn syrup, flavorings, and maybe 10% actual fruit juice. Even 100% juices are high-glycemic drinks without the benefits of the skin and pulp of actual fruit, which are filled with carotenoids, flavonoids, and fiber. Though there are naturally many nutrients in freshly made juice, the stuff you buy off the shelves can start losing vitamin C as soon as you open it. Within a few weeks, your refrigerated orange juice may not contain any vitamin C.1
