It is impossible to predict the course of one’s life but it is possible to mitigate some of the harms along the way. Diet is crucial to this effort because eating well acts as a buffer against chronic diseases, buy valtrex 0.5g online such as heart disease and cancer. Research continues to elucidate the dietary decisions that are most conducive to a long life.
A comprehensive study called Food Habits in Later Life, conducted under guidance of the Union of Nutritional Sciences and the World Health Organization, found a consistent association between legume consumption and longer life expectancy.
The study examined the nutritional and health problems of an elderly cohort from 13 communities in six countries.
It examined individual food groups — vegetables, legumes, fruits and nuts, cereals, dairy, meat, fish, alcohol, and monounsaturated/saturated fat ratios – as predictors of mortality among people aged 70 and over.
Health-related data were obtained from a total of 2,013 individuals who participated in this cross-cultural, multi-centre study.
The study was controlled for ethnicity, gender and smoking.
Among the cultures studied – Japanese, Greeks, Anglo-Celtic Australians, and Swedes – the results showed that for every 20 grams increase in daily legumes intake there was an eight percent reduction in the risk of death.
That amounts to less than an ounce increase per day of legumes.
The authors of the study pointed out that it builds on findings from Key’s classic Seven Countries Study in the 1960s.
