Learn how to build a healthier smoothie with protein, healthy fats, fiber and superfoods to balance blood sugar, boost energy, and support digestion and blood sugar balance.
When you think smoothie, do you think of those monster Jamba Juices? They’re healthy, right? Made with real fruit and all those optional add-in boosts like sorbet and non fat yogurt? (both of which are crazy high in sugar)
Here’s a reality check for you: most of the Jamba Juice classic smoothies contain over 100 grams of sugar. THAT IS 23 TEASPOONS OF SUGAR. You’re meant to have just 25 grams (8 teaspoons) of added sugar, meaning in addition to what is naturally occurring in your food, per day.
Fruit is very healthy and contains antioxidants, fiber, and vitamins, but a common mistake is overdoing the sugar in a smoothie. And we tend to cram the blender full of 3 or more servings of fruit per smoothie. This is not a way to start your day: You’re programming your body to release a surge of insulin (the fat storage hormone) and setting yourself up for blood sugar fluctuations, cravings, and increased hunger for the rest of the day.
But smoothies can be done the right way. Want to know how? I’ll share my secrets for building a better (and tastier) smoothie. My smoothie provides 35 grams of protein which is the perfect way to start off your protein goal for the day.
How to Build a Better Smoothie
Firstly, be mindful of how many servings of fruit you’re adding. You can use 1/2 avocado to make it creamy as a banana alternative. Avocados are a great source of fiber and glutathione, a necessary antioxidant for liver cleansing. I typically do 1/2 banana or avocado for creaminess and 1/2 cup frozen berries.
HOT TIP: for the perfect creamy smoothie, you need about a 1:1 ratio fresh to frozen fruit. I use fresh banana or avocado along with frozen fruit. In the summer, I’ll use fresh seasonal berries. Frozen mangoes also make a very creamy smoothie.
Secondly, DON’T ADD FRUIT JUICE TO YOUR SMOOTHIE. Fruit juice contains nutrients but is mainly fiberless liquid sugar. Use coconut milk or almond milk as the base.
Third, PACK YOUR SMOOTHIE WITH SUPERFOODS. Add a superfood blend that contains spirulina and chlorella. I like and use this super reds & greens formula. You could also add bee pollen for immune boosting, raw local honey if you desire a bit of sweet, various spices (cinnamon is good for blood sugar balance), grated ginger root to enhance circulation and improve digestion, or powdered vitamin C or probiotics. I am also a big fan of moringa in my smoothies (read my post about it here).
OPTIONAL: Add a fiber source for satiety and digestive support: I like ground flax and/or chia seeds, or make it easy and use this fiber blend. The chia provides some omega 3s, too. I’ll also add walnut or almond butter for good fats + fiber, or tahini (sesame paste). It’s very high in calcium.
The final item to remember is to USE A PROTEIN IN YOUR SMOOTHIE. A protein-less smoothie will not sustain you.
Your smoothie should be a mix of the following:
- good fats (from nut butters, avocado, coconut milk, or coconut butter)
- protein (from protein powder or collagen)
- carbs (from fruit, veggies, or pumpkin is a great and easy to digest fiber source).
I recommend collagen peptides, high quality whey, or pea protein for a vegan option. I use and recommend this delicious bone broth paleo protein powder that contains a vitamin-mineral core along with the collagen to provide 35 grams of protein.
What To Avoid in Your Smoothies
I don’t recommend soy protein isolate proteins. If you can handle dairy, I like the Designs for Health whey protein because it is cold processed (the heat in processing/pasteurization destroys the delicate proteins) and is made from high quality whey. But the bone broth protein that’s rich in nutrients is an excellent dairy free alternative.
Also avoid egg white proteins. They’re not a whole food because they exclude the yolks and are highly processed. And remember to avoid fruit juice.
Here’s my basic smoothie recipe
- 1 scoop Protein Powder as appropriate for you and/or 1-2 tbsp collagen. If you tolerate dairy, try a raw unprocessed whey protein like WheyMeal. For dairy free, try or VegeMeal pea protein blend or PaleoMeal bone broth based.
- 1/2 cup non frozen item like a banana or 1/2 avocado. Kiwi is excellent for constipation. I use a mix of fresh and frozen fruit to give my smoothie some thickness.
- 1/2 cup frozen berries, very high in antioxidants
- 1 Tbsp. tahini, almond butter, walnut butter or handful raw nuts
- 1 Tbsp. flax or chia or combo or this fiber blend. Excellent prebiotic to feed your beneficial probiotic bacteria.
- Handful spinach or arugula (optional)
- 1/3 cup coconut milk (lite ok) or almond milk.
- 1 scoop supergreens and reds or moringa
- water as needed to desired thickness (usually about 6 more ounces)
optional add-ins:
- 1/2 tsp cinnamon which is excellent for blood sugar balance
- fiber blend like this one
- 1 tsp maca root which is great for stamina and hormone balance

Conclusion
Smoothies make a fast and super nutrient dense breakfast or snack. Kids love em too!
I love smoothies so much because you can pack them with superfoods like greens blends or spirulina, fiber, antioxidant-rich berries, healthy fats, and protein. They’re super tasty and make a fast and portable breakfast that keeps you full and focused for hours.
Frequently Asked Questions
Why can fruit heavy smoothies cause energy crashes?
Smoothies loaded with tropical fruit can contain a high natural sugar load. Without adequate protein, fiber, and healthy fats, this sugar may spike blood glucose quickly. The rapid rise and fall in insulin can leave you tired, hungry, and craving more sugar.
How much fruit should be included in a balanced smoothie?
Limiting fruit to one serving, such as half a banana or half a cup of berries, helps control total sugar intake. Adding avocado or cooked sweet potato provides creaminess with less sugar impact, supporting steadier energy and improved blood sugar balance.
Why avoid fruit juice in smoothies?
Fruit juice delivers concentrated sugar without fiber, increasing glycemic load. Replacing juice with unsweetened almond milk or coconut milk creates a creamy base with less impact on blood glucose, making the smoothie more filling and metabolically balanced.
What makes a smoothie filling enough for breakfast?
A complete smoothie contains protein, healthy fats, and fiber alongside moderate fruit. Ingredients such as collagen, nut butter, chia seeds, and leafy greens enhance satiety and support stable insulin response, reducing mid morning hunger. My smoothie is typically 35 grams of protein with the bone broth protein and the collagen.
Which protein sources work best in smoothies?
Less processed proteins such as collagen peptides, bone broth protein, quality whey, or pea protein provide essential amino acids with fewer additives. Including adequate protein supports muscle repair and prevents rapid hunger after consumption.
What ingredients should be avoided in smoothies?
Highly refined soy protein isolates, sweetened powders, and fruit juices can disrupt blood sugar and digestion. Choosing simple, minimally processed ingredients supports hormonal balance and long term metabolic health.
How can superfoods enhance a smoothie?
Adding greens powders, spirulina, chlorella, moringa, cocoa, or spices like cinnamon increases antioxidant and phytonutrient content. These ingredients support liver function, immune resilience, and digestive balance when combined with protein and healthy fats.
