Some food guidelines are common: eat local, eat organic, eat whole grains. And more and more nutritionists are paying more attention to foods that combine together well.
 
One restaurant, Rouge Tomate, has an on-staff nutritionist that makes sure that food ingredients used in Rouge Tomate's dishes are combined in a way that maximizes their health benefits. Nutritionist Natalia Rusin makes sure there’s an ingredient high in polyphenols, like grapes to combine with recipes containing fish, to help facilitate the body's absorption of Omega 3.

Keri Glassman who is a Registered dietician and CBS Early Show said the idea of pairing nutrition-dense foods together is gaining popularity. “The more we investigate, the more we learn about the complexities of food, and how food works together.”  For example, there are compounds in yogurt that helps the calcium to be absorbed better than if you took a calcium supplement alone.
 
“It’s going along with what our mothers have always told us: eat your fruits and vegetables. But now, we’re finding a million scientific reasons for why we should actually do it,” said Rusin, who has both a culinary and nutrition background.
