It is difficult to accept at first, but when all is said and done, the processing of the commercial fruit juices on the market today leaves almost nothing but fructose to race through your arteries.
The popular fruit juices that adorn our breakfast tables every morning (excluding freshly squeezed), whether at home or in restaurants, has the skin removed, fiber extracted and has most likely undergone the pasteurization process to kill all bacteria -- good and bad. This includes destroying all the natural enzymes that are alive in the natural fruit which aids in both digestion and other natural bodily functions; pasteurization also destroys a large amount of the vitamins and minerals. The CDC reports that about 98 percent of all fruit juices sold in the United States have been pasteurized. If it's canned, bottled or in a carton, fruit juice does more harm than good.
A study at Baylor College of Medicine found no association between 100 percent fruit juice consumption and weight gain, but it has been shown to increase blood sugar and blood pressure levels, and increase triglycerides. The sudden surge of acidic sugar (no matter what the source) can inflame the arteries, and too much inflammation in the body leads to arterial disease.
A wide variety of the supermarket fruit juices even have added sugar, thus increasing the chance of damage. The manufacturers of these so-called fruit drinks use marketing techniques that fool the public into thinking their products are nutritious when in fact they contain more sugar (or even high fructose corn syrup) than the juice itself. Also remember, whenever a label reads juice cocktail, it will invariably have added sugar.
