National Restaurant Association(NRA) officials say their annual survey of more than 1,800 professional chefs - members of the American Culinary Federation(ACF) - reveals that local sourcing of ingredients, sustainability and nutrition will be the hottest trends on restaurant menus in 2010.

Locally grown produce, locally sourced meats and seafood, sustainability, mini-desserts and locally produced wine and beer top the list of nearly 215 culinary items in the "What's Hot in 2010" survey. Rounding out the top 10 trends are nutritious kids' meals, half-portions, farm-branded ingredients, gluten-free/food-allergy conscious meals and sustainable seafood.

"No one has a better view of restaurant menu trends than the chefs of the nation's nearly one million restaurants, and that is why we survey these culinary professionals on what hot, new trends we'll see in the coming year," said Dawn Sweeney, NRA president and CEO. "The top trends this year - local sourcing, sustainability and nutrition - reflect wider societal trends and consumers' growing interest in these issues. Many restaurants are sourcing some of their ingredients locally, and you often see chefs shopping at farmer's markets to create a host of better-for-you options that today's diners want."

Michael Ty, CEC, AAC, ACF national president, agreed.

"This is retro - it's what we did in the past when chefs relied on local markets because we did not have the luxury of today's transportation system," he said. "We are going back to our roots and the foundation of our craft that made it more pleasurable."

NRA says it surveyed 1,854 American Culinary Federation member chefs in October 2009, asking them to rate 214 individual food/beverage items, preparation methods and culinary themes divided into categories as a "hot trend," "yesterday's news," or "perennial favorite" on restaurant menus in 2010.

The leading culinary theme revealed by the survey issustainability, which is ranked as the third hottest trend. Whether applied to produce, meat, seafood or alcoholic beverages, the concepts of environmentally friendly practices and local sourcing - farm-to-fork - are appealing to both restaurant operators and consumers for several reasons, including freshness, minimal transportation, and supporting local communities and businesses.

Nutritionis another culinary theme that ranks high on the list of trends at number 15. Healthful options for children, produce, superfruits, bite-size and half portions, and food allergy conscious and gluten-free meals all rank in the top 20, illustrating that consumer interest in health and nutrition continues to grow and that restaurants are responding.

Other menu trends in the top 20 include farm-/estate-branded ingredients, regional ethnic cuisine, non-traditional fish (including barramundi and Arctic char), and newly fabricated cuts of meat (including Denver steak and pork flat iron). Simplicity as a culinary theme and smaller portions for a smaller price are also menu trends for 2010, reflecting the shift in consumer preferences toward value and comfort during the economic downturn.

Topping categories within the survey are: amuse bouche and mini-burgers/sliders in appetizers; quinoa and braised vegetables in side items/starches; ethnic-inspired and traditional ethnic items in breakfast/brunch; bite-size desserts and artisan/house-made ice cream in desserts; regional and fusion in ethnic cuisines; and artisan cheeses and black garlic in ingredient.

In the preparation methods category, liquid nitrogen freezing/chilling was ranked as the number-one trend, followed by braising, sous vide, smoking and oil-poaching/confit.

When it comes to sources for trendy food and beverage ideas, the chefs ranked television, trade shows and independent restaurants as the best places to get inspired.
