Last September, travel data service Recruit Lifestyle Jalan, asked adults in a nationwide survey about what they had recently become interested in or concerned about. In the findings, released in February, the top three responses were diet, travel and health and relaxation.

In a follow-up question, subjects were asked, "What topics are you taking more of an interest in now than previously?" Again, the top responses given (in percent) were health and relaxation (62.8), travel (61.8) and food (59.5).

Broken down into age groups, respondents showed increased interest in pursuing a healthy lifestyle across the board. This may account for the recent surge of articles in the weekly magazines about diet, health and avoiding illnesses.
