WASHINGTON — The National Restaurant Association (N.R.A.) has partnered with FoodCALC, Healthy Dining, and Silliker to offer personalized services to restaurants of all types at discount rates.

“Restaurateurs have an increasing interest in obtaining accurate nutrition information of the dishes they serve, but the analysis process has presented challenges,” said David Gilbert, chief operator officer of the N.R.A. “With the new law on nutrition disclosure in effect for certain restaurants, it has become imperative to find solutions to those challenges. That is why we partnered with the best nutrition-analysis providers in the business to meet our members’ needs for customized service at affordable rates.”

Each of the three partners that the N.R.A. has teamed up with offers a different form of analysis. The partners and their services include:

• FoodCALC offers MenuCalc, an Internet-based recipe nutrition-analysis software solution designed for restaurant operators that provides easy-to-use, low-cost options based on individual needs. MenuCalc has 24/7 secure access for multiple users and is backed by a staff of registered dietitians and technology experts and live support.

• Healthy Dining offers a team of masters-level nutrition professionals, registered dietitians and a doctoral level researcher to provide nutrition consultation and analysis services. Services include nutrient analysis (calories, fat, sodium, etc.), allergen declaration, development of gluten-free menus, and guidance in complying with menu labeling legislation.

• Silliker offers expert laboratory, technical and information services to help companies comply with menu labeling requirements. The company’s chemists and research and development professionals are able to help substantiate nutrition claims, and address analytical challenges posed by variables in menu item preparation.
