Here I am, walking through the American Dietetic Association (ADA) Food and Nutrition Expo that is held in conjunction with ADA's Annual Convention. ADA, the nation’s largest group of nutrition professionals, has more than 70,000 members and this huge expo hall is filled with registered dietitians sampling new food products. Booth after booth of vendors are inviting me to sample their goodies. Mind you, no one leaves this expo hungry!
