Whole Foods has selections for special dietary needs such as vegetarian, vegan, GF, paleo, nut-free, soy-free, no transfat, etc. The list just goes on. They are also big on local and organic and educating the public about genetically modified organisms and the negative effects it has on our health and environment.
They have all kinds of gourmet meat and chicken available, you can just buy and put on the grill. Their prices are fair. Sprouts stocks so many diverse food choices, including some cultural foods or gluten free foods that may be harder to find in other stores. They have all the healthier options that we need these days and very few of the overly processed foods we should avoid.
