Whether it's 'The Barefoot Contessa' or 'Tyler's Ultimate,' there's a wide variety of food, cooking, chefs and experts on The Food Network. For the most part, the diversity is great and if you're a food fan -- a foodie -- you can watch FN for hours on end and be entertained.

Any time they touch meat or chicken, there's a camera following them to the sink to wash hands with soap.
