Until recently, fresh fruit or vegetable juice has had an untarnished reputation. After all, what could be unhealthy about drinking down all the nutrients contained in the healthiest foods known to man? But that’s just it, when we drink juice, we aren’t really getting all the nutrients those fruits and vegetables have to offer. And that’s where the opponents of juicing come in — juicing skeptics claim that since we’re missing a few of the nutrients contained in fruits and vegetables, juicing isn’t a healthy option. So what’s the verdict? Should we completely give up fresh juice just because it doesn’t contain all the components contained in whole fruits and vegetables? Here’s how we weigh in:
Some juices aren’t as healthy as others: Opponents of juicing makes some good points, fruit and vegetables juices are missing a lot of fiber, and they can also be high in sugary calories. Fiber is a crucial part of the diet — it provides roughage to ensure proper digestion and stimulates the growth of healthy bacteria. The fiber contained in fruits and vegetables also acts as an anecdote to the high amount of sugar found in many fruits. Fiber actually prevents the absorption of fructose, while effectively carrying it out of the digestive tract.
But here’s the thing, not all juices contain a ton of sugar, and just because you’re not getting all the fiber doesn’t mean that you aren’t getting a ton of other important nutrients. It is, however, probably a good idea to avoid juicing fruits that are high in fructose, like oranges and apples. While these juices can still provide some wonderful nutrients, they supply a high amount of fructose. Too much fructose in one serving can cause fructose malabsorption and the growth of harmful bacteria. If you’re watching your body fat, fruit juices can also pack a significant amount of sugary, fat-depositing calories.
Fruit and vegetable juices demonstrate a number of researched health benefits: The research backing up the health benefits provided by fruit and vegetable juices (especially vegetables juices) is impressive. Juicing provides a convenient way to consume an immense amount of vitamin, minerals, and phytonutrients. These nutrients are responsible for giving beet juice its cardiovascular, endurance, and anti-cancer benefits, carrot juice its anti-colon cancer and eye-health promoting properties, and leafy green juices their ability to improve sugar metabolism.
We prefer to view vegetable and fruit juice as a supplement to a healthy diet: Since vegetable and fruits juices provide so many amazing nutrients and health benefits, it makes sense to include them in your diet. Imagine if you ate a healthy whole food diet, with plenty of fiber, plus you supplemented your daily diet with a glass of freshly juiced greens and carrot juice. You’d be giving your body a great big hug, providing it with the nutrients that can actually help optimize your DNA! Most of us are short on some vitamin and minerals — juicing is an easy way to boost nutrient and anti-oxidant intake with the complex forms found in nature.
Make juices healthier by using them with healthy fats or in smoothies: Some of the most important vitamins vegetables contain are various forms of fat-soluble carotenoids. Since juice doesn’t have any fat in it, your body won’t be able to absorb the fat soluble vitamins very well unless you eat a little fat at the same time. When you juice vegetables, be sure to drink the juice with a meal or eat a little healthy fat, like a tablespoon of extra virgin coconut oil or a few capsules of fish oil, at the same time. Also, since you’re missing out on most of the fiber, try adding your vegetable juice to a smoothie that contains a cup or two of whole fruits and vegetables like frozen berries, whole spinach, or romaine lettuce.
A few other considerations when juicing: Some of the best fruits and vegetables for juicing also tend to be the ones that contain the highest amounts of pesticides. Be sure to only use leafy greens that are certified organic, and wash all root vegetables or fruits that have edible skins thoroughly before juicing. Finally, in order to prevent fructose malabsorption, limit the amount of fruits you juice, and try to emphasize leafy greens and other vegetables.
