We are seeking people aged 65 years or older to help us test eNutri, a Web-based app that aims to record accurate information about what people eat and drink.

You can take part from home. You will be asked to report what you have been eating and drinking using two different online tools. You will also be asked to provide an easy-to-perform finger-prick blood spot test (you will receive a kit in the post).

The study will take place over a 2-week period. If you complete the study, you will receive information about your diet, such as how much fibre, salt and vitamins you have, and how these compare with recommended amounts for your age group. You will also receive tips on how to make your diet healthier.
