I found a difference in the chia vs. salba in my regularity and they say it depends on the soil its grown in and what they do with the plant part, not if they're black or white. I found good sales at Whole Foods when its in stock.

You can add them to salsa and dips too, it will thicken them. Really great to add to pea butter which is naturally runny. The whole seeds can be added to salads, vegetables, anything, they work just the same for me and are a bit cheaper. Whole Foods has the best prices.
