Why is fiber important

Fiber plays an important role in keeping your gut healthy. When it comes to athletic performance, fiber can help support a number of key functions in the body. 

First, it helps slow down digestion and keeps your blood sugar levels steady. This is especially important for athletes who need to maintain their energy levels during long workouts or training sessions.

In addition, fiber promotes healthy gut bacteria. Studies show that athletes who consume a high fiber diet have a more diverse range of gut bacteria, which helps reduce inflammation, boost immunity and support healthy digestion. (1)

High fiber smoothies are a great way for athletes to incorporate more fiber into your diet, and they are also incredibly convenient. Make them ahead of time and store in the refrigerator or freezer.

When you’re short on time, a high fiber smoothie is a great grab and go option that provides nutrients you need to fuel their bodies, maintain your energy and keep you feeling fuller longer.

What can I add to smoothie for extra fiber

One of the best ways to boost extra fiber in your smoothie is by adding high fiber ingredients like chia seeds, flaxseed, berries and leafy greens like kale and spinach. 

These ingredients not only add a delicious flavor and texture to your smoothie, but they’re packed with vitamins and minerals that can help support your overall health, anti inflammatory benefits and sports performance.

Seeds to boost fiber in smoothies

Chia seeds are a great source of fiber, protein and omega-3 fatty acids. When soaked in liquid, they become gelatinous and can add a creamy texture to your smoothie. 

Flaxseed is also an excellent source of fiber, rich source of omega -3 fatty acids and has anti-inflammatory properties.

Leafy greens for more fiber

Leafy greens like kale and spinach are a powerhouse of nutrients, including fiber, vitamins, and minerals. They are also low in calories, making them a great addition to any smoothie.

Nuts and nut butter add extra fiber

Another great addition to high fiber smoothies is peanut butter or another nut butter. Not only does it add a delicious nutty flavor to your smoothie, but it also provides a good source of protein and healthy fats, which can help keep you feeling full and satisfied.
