Introduction
Having an upset stomach can make things seem much more complicated than they really are. One way to combat this discomfort is through smoothies that promote gut health. They’re easy to make with ingredients you probably already have on hand, and they offer a lot of flexibility since you can customize what you use.
You’ll notice that many of the “best” gut health smoothies do not contain highly-labeled superfoods or powdered proteins. Instead, they consist mainly of a combination of fiber, fluid, and gut-supportive ingredients like fruits & vegetables, oats, nuts & seeds, dairy products like yogurt & kefir, and others.
All of which provide needed fiber (soluble & insoluble) that helps reduce constipation, fluid that helps fiber do its job better, and yogurt and fermented dairy products like kefir provide needed probiotics to support healthy gut flora; and many experts agree that increasing fiber intake should be done gradually particularly for those who experience wind or bloating.
If your digestion often feels off and your skin isn’t reflecting your efforts, it might be worth understanding how gut balance affects your overall wellness.
What Makes a Smoothie Gut-Friendly?
To digest a smoothie properly, typically, three things need to be present: fiber, liquid (hydration), and other substances that don’t upset your stomach. Fiber helps to keep things moving through your digestive tract while the liquid helps hydrate the fiber allowing it to perform its natural function. This is one reason why the nutrition information provided by NIDDK recommends consuming enough fiber and drinking adequate amounts of liquid for proper relief from constipation.
Commonly used, high-fiber ingredients for smoothies that promote gut health are berries, bananas, oats, chia seeds, flaxseed, green leafy vegetables, and pears. Additionally, yogurt (especially Greek-style) and kefir may be helpful because they provide probiotics (essentially live bacteria) and protein. According to Johns Hopkins, Greek-style yogurt can increase the amount of probiotics and proteins contained in a single serving of a smoothie, whereas NCCIH claims that the probiotics in yogurt and fermented foods are live microorganisms.
If you have food sensitivities or allergies, we recommend that you stick to the most basic base ingredients possible to ensure that you do not overload yourself with too many unfamiliar ingredients at one time. For instance, people suffering from IBS-like symptoms, typically benefit from adding fiber slowly and keeping track of their symptoms and triggers as opposed to attempting to consume large quantities of fiber all at once.

Tips for Improving Your Digestive System
Perhaps the most popular way to improve digestion through nutrition is to drink smoothies. Unfortunately, one of the biggest mistakes that people make with smoothies is turning them into sugar bombs by using too much juice, sweetened yogurt, or too much fruit, which means the smoothies would have less of a benefit to the digestive system. The key is to strike a balance between fibre, protein and fluid. Even small quantities of nut butter, yogurt, chia seed or flaxseed can change a smoothie from being predominantly sugar to being a healthy option. Johns Hopkins also suggests using yogurts that have the least amount of added sugar.
Additionally, it is wise to increase fibre in your diet gradually. According to NIDDK, there are many uncomfortable side effects to adding fibre to your diet too quickly. All forms of fibre perform better when combined with an adequate amount of fluid, this becomes increasingly important when you experience challenges associated with bloating, constipation, or symptoms that are consistent with IBS.
Below are some simple rules that will help you significantly improve your digestion when you use smoothies as your source of nutrition:
- Beginning with one or two fibre-rich ingredients as opposed to five will assist with digestion.
- A plain yogurt or kefir will provide you with the greatest number of probiotic benefits.
- If you like to keep your smoothies cold, it is acceptable to add ice, but do not add an excessive amount of ice if you find that consuming very cold liquids bothers you.
- Be aware of which foods may cause a negative reaction if you experience IBS or reflux.
- Consume the smoothie slowly, as opposed to gulping it down.
Both NHS and NCCIH acknowledge that certain forms of probiotics may help with certain digestive issues for a percentage of people; however, not all types or strains of probiotic foods perform the same. Thus, it is important to be consistent and to determine which foods provide you with the most benefit rather than attempting to follow the latest trends.
