His patients do know, for the most part, what the bad foods are, Blumenthal said. They're aware of trans fats and know that to avoid fried food. Americans know the rules, but they break them, Blumenthal said. The evidence, he said, is all around us. "Most Americans are overweight or obese."
Blumenthal prefers not to focus on the things healthy eating shouldn't be. "People shouldn't feel overly deprived. We try to emphasize following a healthy, nutritious diet. People do better If you emphasize the good stuff to eat. Fruits, vegetables, nuts and fibers tend to fill you up more," he said, "and they're healthier for you than high-glycemic food like potatoes, rice and white bread."
For those who are more comfortable with packaged programs, Blumenthal advocates the South Beach Diet, whose faddish-sounding name belies the fact that it was developed by a cardiologist, Dr. Arthur Agatson. He also likes the website myfitnesspal.com, which helps users keep a journal of their caloric intake and exercise.
Sampson and Fick will present, along with Dr. Dana Simpler, a workshop on healthy eating on Friday at the Dogwood. Simpler, who will discuss some of the science underpinning nutritional guidelines, thinks that institutional advice could be more explicit about the benefits of a whole-food, plant-based diet.
"I understand it," Simpler said. "Rather than ask a lot and get nothing, they'd rather ask a little and get something. But I think people need to see the science and decide for themselves," Simpler said.
But the basic search for good advice, Lee said, should be over. "There are always things in the gray zone. What's not in the gray zone is that people should exercise more, lower number of calories, less salt, more potassium."
Things that are getting a little easier, even when not dining at home.
