Prof Mark L Wahlqvist, MAI Emeritus Professor, and his colleagues at the National Health Research Institutes in Taiwan, have shown that people who cook at home at least five days a week have a 47 % higher chance of being alive 10 years later.
The study focused on a group of 1,888 men and women 65 years and older living in Taiwan in 1999 and 2000. At the time, participants were asked about their cooking habits, household circumstances, diets, education, shopping habits, transportation, and smoking. They were followed up for 10 years, and during this period, 695 participants died. The findings show that highly frequent cooking (more than5 times/week, compared with never) predicted survival (hazard ratio (HR) 0.47; 95% CI, 0.36, 0.61). Women benefited more from cooking more frequently than did men, with decreased HR, 51% v. 24%, when most was compared with least. The researchers concluded that cooking behaviour favourably predicts survivorship. Highly frequent cooking may favour women more than men.
