Why is Chia Seeds Level 1 on average?
Chia (Salvia hispanica) seeds require virtually no processing between harvest and consumption. The seeds are cleaned to remove plant debris, sometimes sorted by size, and packaged. Unlike flax seeds, which have a hard outer shell, chia seeds are usually sold and eaten whole, because their outer layer is a soft mucilage rather than a hull. This mucilage (which is a soluble fiber called xylose) is why chia seeds form a gel when soaked in liquid, a property that is entirely natural and not a result of any processing. In our analysis, chia seed products average a Processing Score of 1.7, which is Level 1.

Frequently asked questions
Are chia seeds a superfood?
From a processing standpoint, plain chia seeds are about as unprocessed as food gets. Nutritional claims about "superfoods" are marketing terms, not processing classifications. Chia seeds are simply seeds.
Is there a difference between black and white chia seeds?
No processing difference. Black and white chia seeds are just different plant varieties. Both are harvested and cleaned identically. Nutritional differences between the two are negligible.
Are chia seed drinks ultra-processed?
It depends on the brand. A chia drink with just water, chia seeds, and fruit juice is fairly simple. Versions with added sugar, natural flavors, citric acid, and preservatives are more processed.
