6Lucky for Jack, the giant he meets at the top of the beanstalk chasing him with a huge fork does not plan to eat him. He is more interested in nutrition than in devouring Jack. Using the USDA's MyPlate nutrition model, the giant makes Jack a scrumptious meal. As he cooks, he teaches Jack about the food groups--grains, proteins, fruits, vegetables, and dairy--and how much of each should be on Jack's plate. Jack also learns that he should get plenty of exercise, which he does as he climbs back down the beanstalk.
