Technically, yes. In reality, no. Juice is a highly concentrated fructose source, without any of the fruit cellulose or fiber to blunt the absorption. Juice will cause a spike in insulin release. Also, the majority of juices contain added sugar, HFCS, and other stuff. There is absolutely no need for juice in the diet. A Tb or so in a tall glass of water for a bit of flavor? OK every now and then. But not for everyday consumption.
I also think that juice perpetuates my desire for sweets.
