Why is fresh juice healthy for you?

Fresh juice is healthy primarily due to the concentrated nutrients and vitamins present in the raw fruits and vegetables. Here are some key reasons why fresh juice is considered a healthy beverage:

  1. Rich in Nutrients: Freshly juiced fruits and vegetables contain essential vitamins, minerals, and antioxidants. These nutrients play crucial roles in supporting various bodily functions, including immune function, cell repair, and overall health.
  2. Hydration: Juices contribute to your daily fluid intake, helping to keep your body well-hydrated. Proper hydration is essential for various bodily functions, including digestion, circulation, and temperature regulation.
  3. Enzymes: Freshly juiced fruits and vegetables may contain enzymes that can aid in digestion. Enzymes are essential for breaking down food into nutrients that the body can absorb.
  4. Increased Nutrient Absorption: Some argue that juicing makes it easier for the body to absorb nutrients compared to eating whole fruits and vegetables. Juicing process breaks down the cell walls, releasing nutrients and making them more readily available for absorption.
  5. Antioxidants: Fruits and vegetables are rich in antioxidants, which help neutralize harmful free radicals in the body. Free radicals can contribute to oxidative stress, which is associated with various chronic diseases.
  6. Convenience and Variety: Juicing allows you to consume a variety of fruits and vegetables in a convenient and palatable form. This can be especially beneficial for individuals who struggle to eat enough whole fruits and vegetables.

How can you make this Kale Cooler Recipe in a blender?


Use the same ingredients as the juice recipe with the addition of 1-2 cups of water.


  1. Prepare Ingredients:
    • Wash all the ingredients thoroughly.
    • If not using organic produce, peel the apple, lemon, and cucumber.
  2. Chop Ingredients:
    • Chop the celery, apple, lemon, and cucumber into smaller pieces. This will make blending easier.
  3. Blend:
    • Place all the chopped ingredients in a high-speed blender.
    • Add 1-2 cups of water, depending on your desired consistency. You can adjust the amount of water to make the blend smoother or thicker.
  4. Blend Until Smooth:
    • Start blending in your high-powered blender on a low speed and gradually increase to high.
    • Blend until the mixture is smooth and well combined. You might need to stop and scrape down the sides to ensure all ingredients are incorporated.
  5. Strain (Optional):
    • If you prefer a smoother juice, you can strain the mixture using a fine mesh sieve, cheesecloth, or a nut milk bag. This step is optional, as it removes some of the fiber.
  6. Serve:
    • Pour the blended juice into glasses and enjoy immediately.

Blending the ingredients in a blender retains the fiber content, providing additional health benefits. However, it may have a different texture compared to traditional juicing. Adjust the recipe based on your preferences and enjoy this nutritious Kale Cooler Juice!

Can you make the Kale Cooler recipe ahead of time?

While it's generally recommended to consume fresh juice immediately after preparation to retain its optimal nutritional benefits, you can make juice ahead of time with certain considerations. 

Store the fresh juice in an airtight container in the refrigerator, ideally consuming it within 24 to 48 hours to maintain freshness and nutrient content. Choose containers that limit exposure to air and light, which can contribute to nutrient degradation and oxidation. Using opaque or dark containers helps protect the juice. 

Freezing is an option, but be aware that it may alter texture and some nutritional properties.  While making juice ahead of time is convenient, it's essential to be mindful of the potential changes in taste, texture, and nutrient content over time.
