Good diet boosts health but not wealth

The idea that a good diet means a healthy population with lower health costs only holds true when it comes to emergency care, a study shows.

Researchers from Monash University, Taiwan’s National Defense Medical Centre, and Taiwan’s National Health Research Institutes, find that although men and women aged over 65 years who ate healthily had shorter stays in hospital, they were strong users of other medical services.

In fact, they tended to make greater use of outpatient services, preventive care and dental care than those who did not follow a healthy eating regime.

Healthy eating doesn’t mean lower overall medical costs, but does mean that what is spent represents a better health investment, according to the researchers.

Emeritus Professor Mark Wahlqvist, from Monash University’s Department of Epidemiology and Preventive Medicine and the Monash Asia Institute, says individuals with a higher socioeconomic status usually followed a healthier diet and took better care of their health needs, while those on lower incomes were more likely to cut back on basic needs like food and medication.

“A diverse diet can be quite costly, which can lead to food insecurity for low socioeconomic groups who cannot afford it,” Professor Wahlqvist says. “This may partly explain the greater expenditure on acute care that they incur,” he adds.

Professor Walhlqvist claims economic factors play an “inescapable role” in the development of health policies, but the medical costs of diet related and nutritionally related diseases were rarely given attention.

“There is a need for health services to develop a nutrition policy for nutritionally disadvantaged groups,” he says.

The study’s findings have important implications for nutrition related health service policy given that most countries are facing increased medical expenditure as their population ages.

“Such a policy should pay close attention to socially disadvantaged groups with poorer dietary quality,” Professor Wahlqvist says.
