Why should you eat protein smoothies?

  • Smoothies can be a great way to get in more protein! This peanut butter smoothie recipe is full of healthy plant based protein (36g of protein per serving).
  • Adequate protein is important for repairing muscles after a hard workout and is also great for weight loss, as protein helps you feel more satisfied!
    • Tip: Choose a quality protein powder. I personally love Nuzest because it is not only vegan but is a high quality, clean protein powder that doesn’t contain any additives or fillers.

What makes this Peanut Butter Shake so filling?

  • Filled with hidden veggies. Cauliflower is a great addition to any smoothie, and you will never taste it! Using frozen cauliflower helps to add volume to the shake and actually helps the smoothie get a thick, creamy consistency! Adding veggies to smoothies is an easy way to get in a serving or two of vegetables into your everyday routine! This is a great way to get more veggies into your picky eaters!
  • Chia seeds: Chia seeds are full of fiber which can help you feel fuller longer! Added bonus, chia provides a great source of Omega-3 fatty acids!
  • Peanut butter: Because everything’s better with peanut butter! This recipe gets the peanut flavor from 2 places, peanut flour and peanut butter!
    • If you have never used peanut flour, you will love it! It’s the flour left over after the natural fats from the peanuts have been removed. This means the peanut flour packed with protein without all the added fat! It’s a great way to get that peanut butter flavor you love!
    • Some of my favorite brands are Crazy Richards Peanut Powder and Protein Plus Peanut Flour. You can also find Jif Peanut Powder in your local grocery stores as well in the peanut butter section! I like these brands because there is no added sugar in them, just one ingredient, peanuts! If you need a peanut free solution, check out substitutions below!

Did you know that if you are dealing with digestive issues, eating smoothies slowly can be great for your gut and a great way for you to absorb more of the nutrition from your meal! Beware though, some people with stomach issues do not do well with cold food, so listen to your body!
    • Adding toppings is a great way to force you to slow down and chew your smoothie as well. Sometimes smoothies can cause stomach issues because they are consumed too quickly and on the go, so sitting down and eating a smoothie bowl can be helpful if you find that smoothies bother your stomach.
