Diet and Healthy Longevity – Examining the Fine Print in the Evidence

Maintaining a healthy diet is closely linked to longevity. While general advice includes increasing plant-based foods and limiting processed foods and sugars, questions remain if the high-quality dietary patterns, first developed in Western populations, can be applicable to our local cuisines. How about changes in diet after midlife - are they too late in improving health, and how much improvement is necessary? Further, while eating more vegetables and fruits is recommended in general, do fruits and vegetables have different effects with different ageing outcomes? How about specificities and varieties? Are certain fruits and vegetables better than others? Do we still need variety on top of quantity to have optimal effects? In this talk, I will present findings from the Singapore Chinese Health Study cohort over a twenty-year follow-up to examine the fine print in the evidence linking midlife diet to cognitive function, physical frailty and overall health in late life.
