Fruit Juice

Often when it comes to a healthy diet, the nutrients we consume through liquids get overlooked. We’re taking a deeper look at fruit juices. Are they really healthy alternatives to just eating fruit? Let’s find out...

Most people feel virtuous having some pasteurized Juicy Juice in a box with breakfast. Parents tell themselves they've given their kids a healthy alternative to sodas. School snack programs often pack a container of juice for the kids, again, as a healthy bonus. Nutritional regulating bodies consider it a healthy serving of fruit. But drinking juice (like those other beverage favored by kids --milk and soda) can cause an abundance of problems. "Both [soda and juice] are going to promote equal weight gain," says Kimber Stanhope of the University of California, Davis. "Why [is soda considered] the only culprit?"

In fact, a glass of fruit juice typically contains more calories than a glass of soda. Eight ounces of Pepsi has 100 calories, versus 152 calories in an equivalent serving of grape juice and 112 in a cup of orange juice. Even worse, perhaps, is the fact that drinking lots of juice ups the risk of diabetes and heart disease because juice contains simple fructose, which the liver converts to fat more readily than it converts sucrose. Unlike whole fruit (or even unfiltered fresh squeezed juice, for that matter), which breaks down slowly in the body because it contains fiber as well as juice, the pasteurized, purified, strained commercial juice option goes straight to the liver where the overload converts right to fat. Plus, the concentration of fructose in juice far outweighs the amount in a piece of fruit. A single glass of apple juice, for instance, has as much fructose as six apples. That's a whole lot of sugar to consume at once.

Studies have found that drinking 12 or more ounces of fruit juice daily leads to a number of problems. First, in some cases, juice and obseity are linked. A study in 1997 found that kids who drank more than 12 ounces of juice a day had a 3.5 times greater risk of being obese, compared to kids who drank little or no juice. And a 2006 study found that overweight kids who drank an extra glass of juice daily gained an extra pound each year. As if it isn't bad enough, that juice can make kids fat. Other studies have found it can make them short as well. Plus, studies have found that kids who drink lots of juice have a higher incidence of hyperactivity.

So should you absolutely avoid juice? No, because not all juice is created equal. First, there's a universe of difference between a bottle of commercial juice and juice you squeeze yourself. Within minutes of juicing, many of the nutrients and enzymes start to break down, rendering the benefits far less potent. By the time bottled juice gets to your mouth, particularly if it's been processed, it's a mere shadow of its original self. And fresh juice is packed with nutrients -- or should be. Though it's rich in sugar, it's also rich in vitamins, antioxidants, minerals, living enzymes, and an assortment of phytochemicals that your body easily assimilates. It also should be noted that there's actually a whole lot more fiber/pulp in fresh squeezed juices than in the commercial varieties sitting on your grocer's shelves. In addition, in a study we reported on last year found that juice -- particularly grape juice -- prevents plaque from forming on artery walls when consumed with high-fat foods. This means that juice can provide significant cardiovascular advantages that whole fresh fruit alone does not provide.

Also, keep in mind that unlike fresh juices, many packaged juices contain added sugars. Plus, many have been made from reconstituted concentrate, which means even less vitamin content and more chance of mystery ingredients. Also, if the juice isn't organic, it can pack a pesticide punch.

Due to these factors, it certainly is wise to take note of how sugary fruit juice is and to regulate consumption of it. To reap the benefits, just add 50 percent water to the juice to dilute the sugar content, and always, always extract or squeeze your own from fresh, organic fruits and then drink it right away. Also, consider the type of juice: the vitamin and nutrient content varies considerably from one type of juice to another. For instance, blueberry and grape juices contain over 200 percent more antioxidant phenols than apple juice. Yet apple juice has far more antioxidant content than orange or pineapple juices, not to mention its malic acid content that helps soften kidney and gallstones. But fresh pineapple juice is high in the enzyme bromlain, which breaks down rogue proteins and reduces inflammation. The bottom line is that each juice provides its own unique set of benefits. Then again, why not switch over to juicing vegetables, which provide a nutrient punch without delivering the sugar overload (although carrot juice contains plenty of sugar).

So, despite recent reports, fasting one day a week on fresh diluted juices is still one of the healthiest things you can do for your body. Add in a three day juice fast once a month and two one-week juice fasts a year, and you have the makings of a remarkable optimal health program. Also consider a full body detox.
