The Pros & Cons of Smoothies
Most people choose smoothies because they think they’re a healthy alternative to fast food. The problem is that liquid “meals” like these can hit our bloodstream as sugar blasts, which isn’t healthy for anyone but especially people with autoimmune disease. The worst offenders are going to be the store-bought smoothies that sometimes add sugar alongside all the fruit. For example, Smoothie King’s Caribbean Way contains 83 grams of natural sugar (from banana, strawberries, and papaya juice) + 50 grams of added sugar (turbinado) for a total of 133 grams of sugar. Let’s do the math on that: 4 grams = 1 teaspoon of sugar, so that smoothie has 33 teaspoons of sugar (which is 2/3 cup). Keep in mind this is their small 20-ounce size, which most people don’t buy. For their large size, double that.
What about homemade smoothies? Most of us know better than to add sugar, but many smoothie recipes contain a lot of fruit and fruit juice, which can still send us on a blood sugar rollercoaster. Yet when made wisely and consumed as part of a healing diet, smoothies can offer health benefits, too. The Wahls Protocol recommends that we eat 3 cups of greens and 3 cups of brightly colored fruits and vegetables every day for optimal health. Those bright colors represent antioxidants, and each color represents a different type. Greens also contain antioxidants, along with vitamins A, C, K, calcium, magnesium, and folate. These nutrients support our bodies in multiple ways, from reducing inflammation to supporting our natural detox pathways. While we don’t want to drink all our food, smoothies can make it a little easier to meet our nutrition goals. In addition, some autoimmune diseases have symptoms that make smoothies even more appealing. Multiple sclerosis and mysthenia gravis can include the symptom of chewing fatigue. And if you have an autoimmune disease that impacts your digestive tract, blended foods might be easier to digest. Below, I share 5 ways to maximize the pros, minimize the cons, and offer my favorite healthy smoothie recipe.
Tip #1: Always include a healthy fat.
Some vitamins in fruits and vegetables are fat-soluble, which means you need to eat them with dietary fat in order to absorb all of their nutrition. Healthy fats are also important nutrients themselves. They’re essential to brain health, skin health, eye health, immune health, gut health, fertility, body temperature regulation, and blood sugar regulation. So, maximize the nutrition in your smoothie by adding some good fats. Avocado and coconut milk are excellent choices.
Tip #2: Add some collagen protein.
Collagen is a building block for every cell in our body, and it’s used by our intestinal cells to heal and replenish. Since leaky gut is one of the root causes of autoimmune disease, anything we do to help heal leaky gut benefits autoimmune health as well. Another benefit of adding collagen protein (and healthy fats) is that they both help moderate the blood sugar impact of smoothies. They also make them more satiating, so we’re less likely to be hungry an hour later. That said, collagen isn’t a complete protein, because it doesn’t contain all the essential amino acids that meat and seafood contain. However, it does contain beneficial amino acids that are missing from most cuts of meat and seafood. These are proline and glycine, and they play an important role in brain function, heart health, blood sugar regulation, detoxification, digestion, and wound repair. Collagen is also water soluble, so it blends easily into a smoothie.
Tip #3: Choose low-glycemic fruits.
You may have heard these terms in the diabetes community. The glycemic index (GI) measures how fast carbohydrates raise blood sugar compared to pure glucose. However, glycemic load (GL) is the better number to watch, because it takes serving size into account and is therefore a more accurate reading. When it comes to choosing fruits for your smoothie, ideally choose those with a GL of 10 or less. Here’s a database where you can quickly search for the GL of a particular fruit. (Be sure to look at the column all the way to the right, labeled GL). Also choose fruit that’s brightly colored all the way through, to get that antioxidant boost. Here are some excellent smoothie fruit choices: blackberries, blueberries, raspberries, strawberries, cherries, kiwi, nectarines, peaches, and mango. Choose a different blend each time. P.S. Bananas are often included in smoothie recipes because they add a nice texture and natural sweetness. Their GL varies greatly depending on ripeness (from 6-16). This is OK, but just be aware of the amount of banana you add. In my recipe below, I include half a small banana, prioritizing higher amounts of the other ingredients.
Tip #4: Add some greens.
The whole idea of a healthy smoothie is to optimize nutrition, and green leafy vegetables are a great way to do that. Choose a different variety each time, because all foods have a unique nutrient profile. Some greens like kale, collards, arugula, and watercress are also cruciferous vegetables. This is the food group known for containing cancer-fighting compounds that support our bodies’ detox pathways. Arugula is the green most similar to its wild ancestor, making it higher in antioxidant activity than most other greens (although all greens are nutritious). And don’t forget the greens that come attached to root vegetables. These are often edible and nutrient-rich as well, including turnip greens, beet greens, radish greens, and carrot greens.
Tip #5: Drink it alongside a meal.
There are two reasons for this recommendation. One is that liquid food is digested more quickly than solid food and hits the bloodstream faster. Eating food with your smoothie balances out this effect, allowing the energy you get from your food to be slow-released as opposed to experiencing an energy surge and crash. Second, chewing stimulates digestive enzymes, which is essential to absorbing as much nutrition as possible from our food. If you do choose a smoothie as a meal substitute, make that a rare occurrence rather than a regular habit, and take a moment to breathe deeply and relax before drinking it, savoring the flavor. Digestion actually starts in the brain, so that ritual also stimulates digestive enzymes.
