Chia seeds

Chia seeds have been around for thousands of years but it’s only in recent years that they’ve gained popularity due to their “superfood” status. Superfood is not a regulated term and is used more in marketing than in the nutrition sphere. Nonetheless, these foods offer health benefits beyond their nutritional value.

Chia seeds are tiny yet mighty. They contain an impressive amount of protein, fiber, healthy omega-3 fat in the form of polyunsaturated fat, and other nutrients and compounds such as antioxidants. Research has shown that these properties in chia seeds may help lower cholesterol and blood pressure, curb blood sugar spikes, and promote satiety [1, 2].


Bananas are a staple food in many countries. They’re incredibly convenient, cheap, and contain essential nutrients, fiber, and antioxidants. Bananas are also naturally sweet and used in place of sugar in some recipes.

Moreover, research shows that bananas may support digestive and heart health, improve blood sugar and blood pressure levels, and support exercise recovery due to their magnesium, potassium, and electrolyte content [3].


Milk has been part of our diet since the beginning of time and is an easy way to obtain nutrients.

Over the years, we’ve seen an increase in a variety of milk. While cow’s milk is still a part of many individuals’ diets, we now have a wide range of non-dairy milk to choose from, including soy milk, almond milk, rice milk, pea milk, and more.

Milk contains many essential nutrients and calcium is what it is most known for. Calcium is essential for strong bones and health. Health experts often recommend milk as a high calcium source to consume to help prevent bone diseases such as osteoporosis [4].

Cow’s milk and some other non-dairy alternatives also contain a good amount of protein which we need for the growth and repair of cells.

Peanut butter

Peanut butter contains 7-8 grams of protein and other essential nutrients in a 2-tablespoon serving. Health experts recommend adding peanuts and other nuts to the diet due to their heart-healthy omega-3 fat content and nutritional value.

Peanuts are also a good source of antioxidants such as vitamin E, which may prevent cellular damage and risk for chronic disease [5].

Low in carb, peanut butter has a good amount of protein, healthy fat, and fiber that may be a good option for people trying to manage their blood sugars [5, 6].

Unfortunately, peanut butter brands today add ingredients such as sugar and trans fats, reducing the nutritional value. Select a peanut butter that’s naturally made with no additives and with little to no salt.


I’ve been adding chia seeds to smoothies and other recipes for some time. Chia pudding has been all the rage recently and since we eat pudding in my household, I wanted to give it a try.

My original intention was to create a post about chia pudding. I experimented using a standard chia pudding recipe that combines 2 tablespoons of chia seeds with 1 cup of milk and used 3 different types of milk: soy, chocolate-flavored pea milk, and cow’s milk.

I followed the directions, taking time to stir the ingredients at 5 minutes, 30 minutes, 4 hours, and 8 hours. At the 8 hours mark, the consistency was still runny, so I added another tablespoon of chia seeds per recommendations. After more than 12 hours in the fridge overnight, the consistency was still runny.

Chia pudding experiment: chia seeds mixed with different kinds of milk: soy milk (top left), chocolate-flavored pea milk (top right), and cow’s milk (bottom).

My research into this phenomenon revealed that the runny consistency could be due to the brand of chia seeds or the type of milk I used. Others say it may be due to the freshness of the seeds, but I purchased them just days before the experiment.

I created this blog to help people incorporate easy-to-follow and fool-proof recipes. While chia pudding has worked out for others, it didn’t for me, and I cannot recommend it.

Something so simple should not be this complicated.

This is why I believe that a smoothie is a far better alternative to pudding when it comes to adding chia seeds to your diet. No wondering about the ingredients you’re using. No need to stir periodically and wait hours only to find out you have a runny mess.


Ingredients for chia banana smoothie on a cutting board: banana, a glass of milk, a small bowl of ice, a small container of peanut butter, chia seeds in a small bowl, and cinnamon in a 1/8 teaspoon.
  • Banana – For natural sweetness and lends a smooth, creamy texture to smoothies. Use fresh or frozen bananas.
  • Ice if you’re using fresh bananas. I recommend adding it for the icy cool factor but it’s fine without it, too.
  • Milk – Use any milk you like. I have lactose intolerance and typically consume soy milk or pea milk which have a protein content equal to cow’s milk. I used plain soy milk in this recipe.
  • Chia seeds
  • Natural peanut butter with no added sugar.
  • Optional flavors – I like to add 1/8 teaspoon cinnamon or ginger to a smoothie (cinnamon is used here). A 1/4 teaspoon of vanilla adds a nice flavor, too. These are optional and the recipe is just as delicious without them.


Any kind of blender will do for this smoothie recipe.

I use a Nutribullet blender which has been working great for the past 10 years. I’ve even blended carrots in it when making a veggie smoothie. It won’t blend like a high-powered and more expensive blender, but it does the job. I drink my smoothies, my family drinks their smoothies, and we get our nutrients.

A blender is a must-have for creating smoothies along with other recipes. For people who need a fuss-free and quick breakfast or snack, smoothies are a convenient way to get an appreciable amount of nutrients in.

Start with adding milk to the blender followed by the remaining ingredients and blend.

Drink immediately after blending and enjoy!


Will chia seed make me poop?

Yes. Chia seeds can help with regularity due to their high fiber content. A 2-tablespoon serving can have 8-10 grams of fiber.

Overdoing it on fiber is not a good idea as it may cause digestive issues. Experts recommend a moderate intake of no more than 2-3 tablespoons of chia seeds per day.

Can I use other fruit?

Banana is widely available and often used as a smooth creamy base in smoothie recipes. But feel free to reduce or swap out the banana if you don’t like it or want to try it in combination with other fruits.

These other fruits, fresh or frozen, work great in smoothies, too:

– Mangos – The creamy smooth texture is just as good as a banana.
– Strawberries, blueberries, and other berries.
– Cantaloupe and melon
– Pineapple
– Papaya
– Peach
– Kiwi
– Apricot
– Avocado is another creamy base for smoothies but since it’s not sweet like other fruits, the taste may be remarkably different.

Can I use another nut butter or nuts?

Yes. Nut butter like plain almond butter is just as healthy with a good source of protein, fiber, and healthy fat. Nuts can be added and blended smoothly, depending on your blender.

Alternative to peanut butter or nut butter for people with allergies?

Sunflower seed butter is nut- and peanut-free and made from roasted and ground sunflower seeds. Its taste is similar to peanut butter and also contains 8g of protein in a 2-tablespoon serving.

Always check the product label to make sure that the sunflower seed butter is made in a peanut- and nut-free facility.

While allergy to sunflower seeds is rare, it is possible to be allergic to them. Check with your doctor if you’re not sure if sunflower seeds are safe for you.

What other flavors can I add to banana chia smoothie?

As mentioned, I added a little cinnamon to this recipe. But if you want to experiment with other flavors, give these a try:

– A little ginger for zing
– Vanilla
– Adding coconut flakes or swapping out your milk for coconut milk works well with a tropical fruit blend
– Chopped pitted dates or a little maple syrup or honey for sweetness

Can I make this smoothie in advance?

If you’re making any kind of chia smoothie in advance, note that chia seeds will expand and absorb liquid. The smoothie will be thicker after refrigerating overnight. You might like that consistency. Otherwise, a simple solution is to blend it with a little more milk to thin it out.
