Despite their small sizes, it is fairly easy to tell the difference between chia seeds and flax seeds if you are looking at them side by side. For example, chia seeds come in black, white, or brown colors, while flax seeds are golden yellow or brown in color. Flax seeds are similar to apple seeds in both size and shape, while chia seeds are rounded and smaller overall.

When it comes to their taste and textures, chia seeds are much crunchier and easier to consume raw compared to the chewy flax seed.

Chia seeds and flax seeds are frequently used in health food recipes and dietary choices. They are both packed with nutrition and vitamins, so it makes sense as to why they are so popular! You can use both chia seeds and flax seeds in smoothies, on salads, and in a number of culinary applications, though flax seed is best consumed ground compared to whole chia seeds.

In addition to their tougher exterior, flax seeds don’t have any uses when it comes to thickening some dishes, while chia seeds do. In fact, chia seeds are widely used in vegan and gluten free baking and cooking in order to naturally thicken recipes and certain dishes, because of their ability to absorb moisture!

Chia Seeds vs Flax Seeds: Nutrition Information

There’s no denying all of the potential health benefits that occur when you eat either flax seeds or chia seeds. However, flax seeds contain more omega 3’s and healthy fats compared to chia seeds. On the other hand, chia seeds contain more fiber and protein compared to flax seeds, making them a more universal choice when it comes to healthy eating.

Both flax seeds and chia seeds may be popular nowadays for their health benefits, but did you know they were popular in ancient civilizations too? For example, Aztec and Mayan people recognized the benefits of chia seeds, while flax was one of the first crops ever planted in our human history. In fact, the scientific name for the flax plant directly translates from latin to “very useful”. This is because flax has so many other uses outside of nutrition and health, something you may not have known before now!
