Do only Jewish people keep kosher?
Recent studies have shown that, increasingly, those who seek out kosher foodstuffs are from faith backgrounds other than Judaism. People purchase kosher food for health, lifestyle, and dietary reasons. Some people may only purchase kosher food because someone they live with is kosher observant, or because they want kosher observant friends and relatives to feel comfortable eating in their home. It is also a reassurance about the ingredients in a product for those with concerns about animal products, dairy, etc.
