Is juicing good for you?

Is juicing good for you?

Juicing is all the rage these days, with claims that drinking juice extracted from fruits and vegetables will cure health problems, detoxify your body and help with weight loss. Juicing also has been promoted as a great way for people who struggle to eat enough fruits and vegetables to get the vitamins, minerals and antioxidants their bodies need.

So, the questions you’re probably asking are: Should I be juicing? Is it that healthy?

In small amounts, it can help add essential nutrients to your diet. Doing it too often, however, isn’t a good strategy for weight loss or detoxification.

The downsides of juicing

  • Possible calorie overload: Calories can add up fast with juicing, especially if you use more fruits than vegetables. One small orange contains about 60 calories, but one cup of orange juice contains 120 calories.
  • Juicing can be expensive: Juicers often cost several hundred dollars. With juicing, you’ll also go through more produce, adding to your grocery bill. For example, it may take several carrots to get a ½ cup of carrot juice
  • Questionable health benefits: There’s no credible scientific evidence that a diet high in juiced foods cleanses the body. Our liver and kidneys take care of cleansing naturally when we eat healthfully. You may feel better and drop a few pounds with a juice cleanse/fasts, but the weight you lose will be mostly water weight, and the loss short-term.
  • You’ll lose important fiber: Juicing machines pulverize the fruit and vegetables, extract the juice and leave the pulp and fiber behind. Fiber is crucial to your digestive system. It helps with lowering cholesterol levels, stabilizing blood sugar levels, keeping us regular and providing a feeling of fullness. Drinking instead of eating vegetables and fruit makes you feel less satisfied as juice digests quickly in the body. Studies show the best way to feel full is to eat foods high in both fiber and water content such as whole vegetables and fruit.
  • Slow metabolism: After more than three days on a juice cleanse or fast, your body starts breaking down muscle mass for protein, slowing your metabolism. Because juice cleanses and fasts are low in protein (and usually calories), following them can give you headaches, lightheadedness, dizziness and low blood sugar.

Get the benefits of juicing without hurting your health

  • Drink small amounts to keep calories down: Eight ounce serving for vegetables, four to six ounces for fruit.
  • Include whole fruits and vegetables in addition to juice: Make sure you’re getting enough fiber. Eat fruit for a snack twice a day. Double your vegetable serving at lunch or dinner, including using them in soup or stir-fry.
  • Use the leftover pulp from your juicer: Add it to soups, veggie burgers, muffins and more for additional fiber
  • Consider using a blender instead of a juicer. Blending retains fiber. Not all vegetables work in the blender, but there are still many possibilities and fun combinations to explore. Smoothies are a great way to get your nutrients and fiber, too.
  • Add protein and healthy fats to your concoctions: For dietary balance and to increase satiety (feeling full), add yogurt, milk or milk alternatives, nuts and nut butters, powdered peanut butter (PB2), ground flaxseed and chia seeds.

  1. Juicing ran my blood sugar up extremely high. I only juiced the one time, never again. If I do juice again it will be mostly vegetables and in small amounts, as was suggested in this article.

    • Hi Charlene. Sorry to hear that you had a bad experience with juicing. I agree with you about using mostly vegetables. TI mentioned in the article about adding protein and/or healthy fat to the mixture to slow down the absorption of carbs. You could also have the protein on the side such as 1-2 hard-boiled eggs or a small handful of nuts.

  2. Great article. learned a lot. Thank you Heather!

  3. Very informative offering the pros and cons as well as finding sensible ways to juice!

  4. I just heard about this same thing on the morning show following the channel 9 news. I was over doing the fruits. I never added vegetables, because I have vegetables with dinner. My daughter told me I need to add vegetables with my smoothies. I have always used a blender, because as mentioned earlier, the juicers are too expensive. I also always added flax seeds to my smoothies, but now I know how much vegetable and how much fruit to add to my smoothies. The peanut butter I will try also, I can’t eat peanuts too often due to allergies. Thank you for this information, Heather.

    • Hi Donna. Glad you are using a blender for your smoothies to keep all the beneficial fiber! Also glad you are using less fruit and including more veggies in your smoothies! It never hurts to eat more non-starchy veggies. I like to add spinach or kale to my smoothies. I buy it fresh and freeze in storage bags so I always have it handy for smoothies.

      In place of peanut butter, you could use other nut & seed butters if you are aren’t allergic. Almond butter, sunflower seed butter, and tahini are all great in smoothies, providing healthy fat and creaminess. If trying to keep weight in check, just remember portion control with nut and seed butters (about 1 to 2 Tablespoons).

      Wishing you a happy and healthy New Year Donna!
