The Scoop on Choosing a Protein Powder
Protein is an important nutrient for our health. Proteins are made of small molecules called “amino acids” that serve as the building blocks for nearly every tissue and chemical in our body. Having an adequate dietary source is important to help control weight and muscle mass, balance blood sugar and prevent cravings, and appropriately drive metabolism.
Adding a scoop of protein powder to a smoothie can be a quick and easy way to boost protein consumption. But not all protein powders are created equal.

Having an adequate dietary source is important to help control weight and muscle mass, balance blood sugar and prevent cravings, and appropriately drive metabolism. The daily intake of protein in an adult should be about 1 gram per kilogram of lean body weight however, your protein needs can vary based on your metabolic health, activity level and other medical conditions.
Adding a scoop of protein powder to a smoothie can be a quick and easy way to boost protein consumption. But, not all protein powders are created equal. Consider these options when selecting your product:
Whey
Source: Whey is a protein components in cow’s milk.
Pro: Whey is highly bioavailable, meaning it can be easily used by your body.
Con: Cow’s milk is a common gut irritant that causes low grade systemic inflammation for many people without them ever realizing it.
Good for you if: You are an athlete and want more lean muscle mass. You tolerate dairy well. You get it from a good source (organic, grass-fed, minimal ingredients, no thickeners, no sweeteners).
Casein
Source: Casein is also a protein in cow’s milk.
Pro: Casein is also easily used by the body.
Con: Casein can cause allergic reactions or upset stomach for those with dairy sensitivity. It also takes longer to digest than whey.
Good for you if: You are an athlete and want more lean muscle mass. You tolerate dairy well. You get it from a good source (organic, grass-fed, minimal ingredients, no thickeners, no sweeteners).
Beef Isolate Protein
Source: Various cuts of beef
Pro: Beef protein isolate is an animal source of protein that is not derived from milk. It is an excellent source of essential and collagen specific amino acids.
Con: The quality of the protein may be dependent on the cut of beef processed. Beef isolate protein is not as bioavailable as whey protein. It has a very specific taste and may clump together or not fully dissolve in liquid.
Good for you if: You want to avoid dairy, legumes and grains or are dairy sensitive. You get it from a good source (organic, grass-fed, minimal ingredients, no thickeners, no sweeteners).
Soy
Source: Soybean plant
Pro: Soy is a plant-based protein that is an alternative for those with dairy allergies or sensitivities. Soy is one of few plant foods that offers a full profile of amino acids that our bodies need.
Con: Research suggests that some soy consumption is safe, however, some still worry about the hormone-like compounds that soy contains.
Good for you if: You are vegan. You tolerate legumes. You get it from a good source (organic, minimal ingredients, no thickeners, no sweeteners).
Pea Protein
Source: Plants; usually yellow peas.
Pro: Pea protein is considered hypoallergenic meaning it is unlikely to cause an allergic reaction or food sensitivity.
Con: Peas do not contain the full spectrum of amino acids.
Good for you if: You are vegan. You mix it into other blends of protein (e.g. hemp or rice) to get all the necessary amino acids. You tolerate legumes. You get it from a good source (organic, minimal ingredients, no thickeners, no sweeteners).
Rice Protein
Source: Rice
Pro: Rice is also hypoallergenic, plus it may have an extra dose of B vitamins and fiber.
Con: Rice contains a small amount of carbs.
Good for you if: You are vegan. You are not paleo. You mix it into other blends of protein (e.g. hemp or pea) or nuts and seeds to get all the essential amino acids. You tolerate grains. You get it from a good, high-quality source (organic, minimal ingredients, no thickeners, no sweeteners).
Hemp
Source: Hemp seeds (from the cannabis plant)
Pro: Hemp is hypoallergenic and is a source of complete protein. Hemp has all the 9 essential amino acids and contains an extra dose of omegas.
Con: Hemp is the least bioavailable of the lot, meaning your body doesn’t absorb and use it as well as other sources.
Good for you if: You are vegan. You are paleo. You get it from a good, high-quality source (organic, minimal ingredients, no thickeners, no sweeteners).
Collagen
Source: Animal connective tissue, often bovine hide or wild-caught white fish (marine collagen)
Pro: Collagen can be good for skin and joint health.
Con: Collagen is often considered a beauty product and comes with a lot of hype. Many label promises are not proven. Collagen is not a complete protein. It only contains 8 of the 9 essential amino acids. These amino acids are not equally balanced, as the ratio is skewed towards glycine, proline, and hydroxyproline.
Good for you if: You are not vegan. You are paleo. You don’t mind spending a bit extra to get the good stuff. You get it from a good, high-quality source (organic, grass-fed, minimal ingredients, no thickeners, no sweeteners).
Spirulina
Source: Blue-green algae
Pro: Spirulina is a complete protein plus gives extra minerals and antioxidants.
Con: It is hard to know where it comes from.
Good for you if: You are vegan. You are paleo. You tolerate chlorophyll-containing drinks. You get it from a good, high-quality source (organic, minimal ingredients, no thickeners, no sweeteners).
And the winner?
In my opinion, a mixture of rice and pea protein is the winning combo. The combination makes up the full spectrum of essential amino acids, while being plant-based, and free of common irritants like casein, lactose, gluten, or soy.
One final note of caution: unfortunately, the FDA does not regulate protein powders, so you have no way of knowing what’s actually in them. Do your homework to make sure you’re getting protein powder from a trusted source. Ensure your protein powder is free of added sugars and artificial coloring or preservatives. Ideally, it will be certified by a third party stating it is low in heavy metals.

Building a Better Smoothie and Dr. Leazenby’s Favorite Recipe
We all know that we should be eating more fruits and vegetables, but its not always the most convenient choice in our busy American lifestyle. You have to get creative and plan ahead to find strategies that work for you. I frequently teach the "4 S’s" to my patients and my students as ways to incorporate veggies into your diet. These include Soups, Smoothies, Stir-fries and Salads. All of these are versatile options for incorporating plenty of nutritious foods to support your health.
Let's look closer at smoothies. They are a great option for any meal of the day. The can be made sweet or savory and can accommodate a large variety of ingredients. However, they can also quickly become unbalanced and sugar-laden when made with too much fruit juice, sweetened yogurt, or large amounts of high-glycemic fruit. The following tips can help make smoothies a nourishing part of your diet.

However, they can also quickly become unbalanced and sugar-laden when made with too much fruit juice, sweetened yogurt, or large amounts of high-glycemic fruit. The following tips can help make smoothies a nourishing part of your diet.
Add veggies. Fruit is delicious and wholesome, but even in high quantities this natural sugar can send our blood sugars spiking. Leafy greens like spinach and kale add to the nutrient density of our meal, but do not contribute additional sugar. Avocado can add creaminess and a luscious thickness while providing a great source of fiber and healthy fat. Cucumbers can be a refreshing way to add flavor, fiber and water to smoothies.
Add protein. Our bodies ideally want every macronutrient (protein, fat and carbohydrate) available in every meal. Adding protein to smoothies helps fuel the body through the day and provides essential building blocks for health. Add nuts like cashews or almonds, beans like chickpeas or white beans or consider a high quality commercially available protein powder.
Use a spoon and a bowl. Proper digestion starts in our brain and requires a mindful approach to eating. Sitting down to a table and chewing your calories is preferable to quickly gulping down your smoothie. When you are able, turn your smoothies into a smoothie bowl. Simply add less liquid to your smoothie to make it thick like the consistency of soft serve ice cream. Serve the smoothie as a bowl topped with fruit, nuts or your favorite granola. You may find you feel fuller faster.
The Ultimate Smoothie Bowl Recipe
Smoothies can be a great on-the-go breakfast. Including vegetables, protein and healthy fats help ensure these tasty drinks provide a steady source of energy rather than a sugary spike and crash. To help promote mindfulness and proper digestion, consider making your smoothie thick and eat it from a bowl with a spoon.
Author: Erica Leazenby, MD Time: 5-10 minutes
Serves: 1
Ingredients for a balanced smoothie:
1-2 veggies: Get creative and include a variety of veggies like a handful of spinach or kale, a piece of cooked sweet potato, steamed cauliflower, half a cucumber or cooked white beans
1-2 fruits: Prioritize fruits like raspberries, blueberries and cherries that are less likely to spike blood sugars; tropical fruits like pineapple and mango can cause more significant blood sugar spikes, so use them more sparingly
Healthy fat: Adding a 1/4-1/2 of an avocado, tablespoon of nut butter or a spoonful of seeds can provide healthy fats that help keep you full and promote absorption of fat soluble vitamins
Protein: Add unsweetened yogurt, hemp seeds, nut butters, chia seeds, flax seeds or plant-based protein powders
Liquid: Nut based milks, teas or ice are great bases for smoothies; avoid fruit juices to help control the amount of sugar
“Extras”: Give your smoothie an extra flavor jolt with antioxidant spices like cinnamon, unsweetened cocoa, ginger and turmeric
Dr Leazenby’s Favorite Sweet Cherry Smoothie Bowl
1 cup spinach
1/2 cup frozen cherries
1 serving chocolate flavored, plant-based smoothie powder (I like OptiCleanse Creamy Chocolate by Xymogen. This is available in the Relish Health office.)
1/2 cup or more unsweetened almond or cashew milk
1 Tablespoon flax seed
Optional toppings: nutty granola, unsweetened coconut flakes, helm seeds, pumpkin seeds, berries, a few banana slices
Combine all ingredients in a blender. Adjust amount of almond milk to desired consistency. Periodically scrape down the blender to incorporate all the ingredients. Serve in a bowl with your favorite toppings.
