The Center’s Specialized Infrastructure

One of our researchers’ most important resources is a comprehensive nutritional database, a unique tool developed at the Center. The database is a core component of research methodology and is an asset heavily used by all Center members. The database contains caloric and nutritional information for thousands of foods, allowing researchers to track participants’ eating habits. This research tool continues to evolve, taking into account new f​​ood trends, local food patterns, new assessment measures, and more. The nutritional database is an indispensable research tool enabling researchers to maintain and analyze data, compare results, and validate results. 

The center also provides additional non-traditional methods for dietary assessment using newly developing qualitative scores for the diet. These tools are used in our studies, as well as in paid services to other research centers.
