Chia seeds can be made into energy drinks quite easily – but yes…if seeds cause issues stay away. They don't need to be ground though, your body will absorb the nutrients out of them whole (unlike nearly every other seed). They swell up in water – it is amazing to watch.
But they are also very, very high in fiber so YMMV. The big reason to eat Chia if you can is that it binds cholesterol like few other food items. This past year I dropped my and my husband's cholesterol levels by half by removing most meat and animal products and adding things such as Chia to our diets. I grind it though as I hate picking it out of my teeth … yuck!!
