It depends. Diversity of thought is extremely important to avoid complacency in a dynamically changing marketplace.
If your company is providing services to specifically white men and women in the 20 to 60 age group, you have a pretty good mix of people. You could use somebody who isn't in the target demographic like most of you to help you out of the demographic Johari window, but otherwise your diversity is perfect.
If you're trying to market to people who need food around the world, you will at some point hit a wall on how much you can understand all the different markets. For instance, what do a bunch of white guys from the suburbs know about how a Sub-Saharan African interacts with food markets?
