Is First Watch Kale Tonic Healthy?

Yes, the First Watch kale tonic is essentially a sweet green juice. Green juices are a natural source of chlorophyll, live enzymes, vitamins and minerals: all of which are healthy!

First watch’s kale tonic mentions kale as an ingredient but since the juice is so sweet, I’m lead to believe that there isn’t a lot of kale in it. I believe that the juice is primarily made up of apples and cucumber.

What Are the First Watch Kale Tonic Ingredients?

The ingredients in the First Watch kale tonic are:

  • Fuji Apples
  • Kale
  • English Cucumber
  • Lemon

How to Make First Watch Kale Tonic Recipe?

  • Step 2: Run the kale, cucumber, apples and lemon through the juicer.

Ingredient Substitutions

  • Fuji Apples: Instead of Fuji apples you could use other apples that have a sweet and mild taste including Golden Delicious, Honeycrisp, Ambrosia, Gala or Red Delicious apples.
  • English Cucumbers: If you don’t have English cucumbers you could use regular cucumbers instead. If you use regular conventional cucumbers make sure to peel the skin in order to remove the wax. Wax is bad for your health because it could trap fungus and bacteria. It’s also made with fungicides. Hot house cucumbers taste the most similar to English cucumbers because they have thin skin and smaller seeds. The large seeds in conventional cucumbers makes the juice taste more bitter.
  • Lemon: If you don’t have lemon you could use lime instead.
  • Kale: No Kale? No problem! Collard greens, romaine lettuce or spinach would work well in place of kale.

What is First Watch?

First Watch is an American Chain Restaurant that specializes in serving breakfast and brunch. Only open until 2:30 in the afternoon, First Watch offers up menu items like the kale tonic, avocado toast, pancakes and other breakfast items.

They constantly receive high customer satisfaction ratings. I can personally tell you that if you want to get a table at First Watch on the weekend, be prepared to wait. This popular breakfast chain is always busy!

How to Store Leftover First Watch Kale Tonic

Kale tonic is best consumed fresh because as soon as you juice the produce it becomes prone to oxidization. And it looses vitality immediately. While it won’t be as fresh it won’t go bad for up to 1 day in the fridge. You can store it for up to 48 hours in the fridge in a glass container with a rubber seal. Like a mason jar!

Some of the benefits of kale juice include getting an infusion of vitamin K, antioxidants and beta-carotene. Furthermore, drinking kale juice can help you maintain a healthy weight, support heart and ocular health according to this evidence based article on Healthline.
