The UK LLC includes diet data from many studies. These studies have collected diet data using differnet tools. By merging all these data together health scientists will have more powerful data to understand links between diet and disease. This is important as there are gaps in our knowledge. Gaps include how sex, social group and age may change peoples diet and health. The dietary data in UK LLC were obtained with different tools. An important first step is to merge these data. We have a proven method to do this. We will first assess the range of tools used. Next we will assemble a group of experts to agree how to combine data. Finally we will write computer code to merge the data in a consistent way. When we finish, future researchers will be able to do important studies. This will lead to better diet advice and better health.
