I love my daily smoothies, but juicing is very different, and I don't do a whole lot of it. Juicing can have some awesome benefits, but only if you do it right...so I thought I would give you just a few things to consider. First, you have to keep one important thing in mind - if you're going to juice (and you want it to be healthy), you have to go heavy on the veggies and light on the fruit. A good vegetable-to-fruit ratio would be somewhere around 4:1.
The problem with fruit juice is that you're consuming all of those concentrated fruit sugars, but you've taken away any fiber to help slow the absorption of the sugar into the bloodstream. And, you're typically consuming far more of it than you would in a single serving of fruit. For example, an apple may have 10 grams of sugar, but it takes more than one apple to make a glass of apple juice. So, when you drink a glass of fruit juice, you're consuming FAR more sugar than what is typically in a single serving of fruit, AND concentrating it, AND removing the fiber.
Vegetables are far lower in sugar, however, and juicing them allows you to concentrate and consume many different nutrients and vitamins at once, and your body can absorb and digest them easily. Juicing vegetables can have great benefits for things like liver detoxification, nutrient absorption, and easy digestion.
Another thing to consider is that juices should be fresh, raw, and cold-pressed. Pasteurization and time both destroy the nutrients you want to get from the juice. When you consume juice from the grocery store shelves, you honestly may as well be consuming soda. Sad, but true.
Lastly, juices are not a source of balanced nutrition, so they CAN be a healthy addition to your diet, but typically not the main course. (Oh, and I would certainly advise against ever juicing with conventionally-grown produce. That's a whole lot of chemicals and pesticides concentrated in your juice and absorbed by your body!)
I'm curious what you think. Do you juice regularly? Why or why not?
