Diet and healthy ageing

In the future there will be more people aged 65 years and over ('older adults'). Although the exact mechanisms underlying normal ageing are not fully understood, ageing is generally associated with an increase in chronic diseases, such as cardiovascular disease, diabetes, cancer and osteoporosis. It is becoming clear that it is possible to prevent, slow or reverse the onset of many these by modifying lifestyle factors such as diet. Studies of older adults in a range of countries have highlighted a number of areas in which dietary quality could be improved. It is important to identify dietary patterns in addition to specific dietary components that offer protection against chronic disease. The challenge in the area of diet and healthy ageing is twofold: first, there is a need to improve the diet of older adults; and second, as most chronic diseases begin earlier in life, there is a need to encourage other age groups to adapt their diet so they can enter old age in better health.
