"The workplace 100 years ago was a farm, and you probably did not need any healthier lifestyle changes. Today it's a desk and a computer," she said.
She said human bodies are hardwired to enjoy fatty, sugary foods but, at the same time, people typically do not miss those foods if only healthy options are presented.
"We're hardwired in many people to like fried chicken better than baked chicken. But we also know, when you're hungry, you will eat and it will taste good."
The guidelines memo also included sample menus, suggesting turkey chili with crackers and fresh fruit for lunch, or a turkey sandwich on whole grain bread with low-fat cheese, lettuce and tomato with a side of potato or pasta salad made in a light dressing.
A sample dinner menu could include spaghetti and meatballs, but with whole grain or low-carbohydrate pasta, tomato sauce and whole grain rolls.
Although the switch from sugary soda was not a hard sell, Frazer said there has been some pushback from employees over the healthy food requirements.
"There was the thought that everything had to be baked rather than fried. I think there was a momentary questioning of, does this mean we have to give up fried chicken?" she said.
No, Frazer said, it does not mean anyone has to give up fried chicken. It just means that grilled chicken, salmon or a healthy sandwich also will be available.
