That’s definitely a shame, considering getting adequate fiber (both soluble and insoluble) in your meals will not only keep you feeling satiated, but it can also directly aid digestive regularity, support a healthy gut microbiome, and even maintain healthy blood sugar levels. Your go-to smoothie is likely already rich in an array of fruits and vegetables, but if you’re low on fiber (and odds are, most of us have a fiber deficit), this is one of the easiest meals to modify for a quick boost. Not sure which ingredients will do the trick? Experts share some staples to consider adding to your morning drink to optimize digestion and fuel your body throughout the day: FYI: Beta-glucans are a type of fiber linked to an array of benefits, including gut, heart, and immune health—plus they can help support healthy blood sugar levels (more on the bioactive plant compound here). As for the oats themselves, “not only will they pack in fiber, they will also add some texture [to your smoothie], and make it more filling,” adds Valerie Agyeman, R.D., and host of the Flourish Heights podcast. What’s more, adding chia seeds can help thicken your smoothie and make it even more hydrating! In fact, on a mindbodygreen podcast episode, nutritional psychiatrist Drew Ramsey, M.D., shared how he actually encourages eating chocolate for breakfast, due to its antioxidant properties (more on that here). Not to mention, it will elevate the flavor of just about any smoothie formula. For a delicious combination (plus a nice balance of protein, carbs, and healthy fats), try pairing it with a banana and a scoop of peanut butter.
