Introduction

Smoothies have become increasingly popular for the past several years for a good reason. They are fast and customizable, in an easy way to pack nutrient-dense foods. But not all smoothies are created equal from smoothies coffee shops, restaurants, and of course homemade. Some are loaded with added sugar and lack the key components that keep you full and energized, turning what seems like a better option as a meal replacement to a hidden calorie bomb. The “healthiest” smoothie strike the right balance between flavor and nutritional density. Whether your goal is to fuel workouts, manage your weight, or simply get your fruit and vegetables for the day, building a smoothie with the right nutritional foundation can make all the difference. In this post, i’ll break down the essential components of a well-rounded smoothie from protein, fiber, vitamins and minerals so you can blend with purpose in sip your way to better health. 

Foundation of the smoothie

The foundation of the smoothie typically makes up a majority of the recipe. Foundations such as water, milk, yogurt, or plant based milk such as soy milk or almond milk. Below is a table summarizing the calories, protein and nutrients of each. 

1 cup	Calories	Protein	vitamins/minerals
Whole milk	150	8-9	Calcium, vitamin D, vitamin B12,vitamin A, phosphorous, potassium
2% milk	120-130	8-9	Same as whole milk
1% milk	100-110	8-9	Same as whole milk
Fat-free milk	80-90	8-9	Same as whole milk
Soy milk	80-100	5-9 (vary by brand)	Calcium, vitamin D, vitamin A, Vitamin B12, potassium, ½ phosphorous compared to cow milk
Almond milk	30-40	1	Calcium, vitamin D, vitamin A, B12, ½ potassium compared to cow milk and soy milk, little phosphorus
Greek yogurt (plain, nonfat/low-fat)	100-120	15-20	Calcium, vitamin D, potassium, probiotics
Low fat yogurt	110-130	6-8	Calcium, vitamin D, 1.5 times more calcium than greek, probiotics

As you can see, all of the dairy milks have the same amount of protein of 8-9 grams and the same vitamin and mineral matrix. That being said, substituting a fat free milk or 1% milk will contain fewer calories with the same nutrients. Almond milk has the least amount of protein. Keep in mind that some are thicker than others. For example, greek yogurt is usually thicker than low fat yogurt. If you’re using a thicker base, you may require more of the base to make a smoothie to your texture preference. For example, you may need two cups of greek yogurt versus one cup of low fat yogurt. Or you may need to add milk to thin the greek yogurt.

Fiber addition

Did you know that over 90% of Americans do not meet the daily fiber recommendation? That being said a smoothie is a perfect way to add additional fiber to your day. But be warned if you don’t usually eat a lot of fiber foods, adding them all at once might cause constipation or diarrhea. The goal would be to slowly introduce fiber to your diet. That being said below is a list of high fiber additions:

Foods that add >4 grams of fiber

Blackberries or raspberries	½ cup
Coconut	1 oz
Spinach	½ cup
Avocado	½ cup
Banana	1 medium
cherries	10 cherries
pineapple	½ cup
Chia seeds	1 tbsp

Common foods that add nutrition and calories to smoothies. Certain foods can be nutrient dense and energy dense. While they have great nutrient composition, they can also add calories really quickly depending on how much you add to the smoothie. A few examples are listed below.

	Serving	Calories	Benefits
Avocados	½ cup	120	Monounsaturated fats (heart healthy), Fiber, potassium, antioxidants
Peanut butter	2 tbsp	190	Protein, monounsaturated & polyunsaturated fat, vitamin B3, magnesium, antioxidants
Sunflower butter	2 tbsp	190	Vitamin E, polyunsaturated fat, magnesium, iron
Chia seed	2 tbsp	120	Omega-3 fatty acids, protein, fiber, calcium

Optional boosters

Seasonings are a great way to add nutrient benefits to your smoothies!

Turmeric	Anti-inflammatory and antioxidant
Ginger	Helps with digestion, anti-inflammatory, immune support
Cinnamon	Regulates blood sugar, antioxidant
Matcha	More antioxidants that green tea

Add protein powder or not? 

Most of the protein in smoothies come from the base as milk or yogurt. Additional protein can come from adding nut butters and seeds. It is suggested to have at least 30 grams of protein per meal. If you are using the smoothie as a meal replacement, then yes, protein powder may be needed to meet your needs for that meal.  If you are eating a meal and have a smoothie as a supplement, then you may not need the powder. Of course the standards are different depending on body size, age, goals, and physical activity level.
