The Trinity-Ulster-Department of Agriculture (TUDA) study was launched in 2008 and aims to:

1. Provide a better understanding of how food, nutrition, genetics, health, lifestyle and environmental factors can impact on diseases of ageing, with a particular emphasis on cardiovascular disease, dementia and osteoporosis.

2. Generate evidence to influence public health policy and develop strategies aimed at promoting healthier ageing through improved nutrition.

3. Generate opportunities for functional food development to support healthy ageing.

It is one of the most comprehensively characterised resources of its kind for ageing research internationally, providing extensive phenotypic, environmental and genetic information on over 5000 older adults.
