There's sunflower seeds in my guinea pig's food?

My guinea pig got switched to another brand of food. This food has sunflower seeds and I don't like it. I've been taking off the shells and giving her the inside, but should I remove them altogether? Also, what's a good brand of guinea pig food? I like foods that have little tidbits in them, and Brownie doesn't really like plain pellets. She needs to have a little variety in her food! Most guinea pig foods seem to have a lot of artificial coloring and it's hard to find a good brand.
