Costs of Eating Healthy Pay Off Over Time

Eating healthy costs a little bit more every day, a new study says. But in the long run, a healthy diet costs very little compared to the lifetime cost of treating diet-related chronic diseases, said the study's authors.

 

The study, published this week in the journal BMJ Open, analyzed diet and price information from 10 countries. It showed that people who eat a very healthy diet—one that is rich in fruits, vegetables, nuts and fish—would spend about $1.50 more per day than those who eat a less healthy diet comprised of processed foods, meats and refined grains. Over a year, that cost difference would represent about $550.

"This would represent a real burden for some families, and we need policies to help offset these costs," Dr. Dariush Mozaffarian, an associate professor at Harvard School of Public Health and senior author of the study, said in a media release. "On the other hand, this price difference is very small in comparison to the economic costs of diet-related chronic diseases, which would be dramatically reduced by healthy diets."

 

The researchers conducted a meta-analysis of 27 existing studies from 10 high-income countries that included price data for individual foods and for healthier versus less healthy diets. They evaluated the differences in prices per serving and per 200 calories for particular types of foods, and prices per day and per 2,000 calories. Both prices per serving and per calorie were assessed because prices can vary depending on the unit of comparison.

 

The researchers suggested that unhealthy diets may cost less because food policies have focused on the production of inexpensive, high volume commodities, which has led to "a complex network of farming, storage, transportation, processing, manufacturing and marketing capabilities that favor sales of highly processed food products for maximal industry profit."

 

Creating a similar infrastructure to support production of healthier foods might help increase availability—and reduce the prices—of more healthful diets, the researchers said.

 

"People often say that healthier foods are more expensive and that such costs strongly limit better diet habits," lead author Mayuree Rao, a junior research fellow in the Department of Epidemiology at Harvard, said in the release. "But until now, the scientific evidence for this idea has not been systematically evaluated, nor have the actual differences in cost been characterized."

What Does "Recovered From Coronavirus" Mean? Four Questions Answered

The coronavirus is certainly scary, but despite the constant reporting on total cases and a climbing death toll, the reality is that the vast majority of people who come down with COVID-19 survive it. Just as the number of cases grows, so does another number: those who have recovered.

In mid-March, the number of patients in the U.S. who had officially recovered from the virus was close to zero. That number is now in the tens of thousands and is climbing every day. But recovering from COVID-19 is more complicated than simply feeling better. Recovery involves biology, epidemiology and a little bit of bureaucracy too.

We Can Restore Marine Health, Study Says

The future for the world's oceans often looks grim. Fisheries are set to collapse by 2048, according to one study, and 8 million tons of plastic pollute the ocean every year, causing considerable damage to delicate marine ecosystems. Yet a new study in Nature offers an alternative, and more optimistic view on the ocean's future: it asserts that the entire marine environment could be substantially rebuilt by 2050, if humanity is able to step up to the challenge.

Bread has been a source of basic nutrition for centuries, the holy trinity being wheat, maize and rice. It has also been the reason for a lot of innovation in science and technology, from millstones to microbiological investigations into a family of single-cell fungi called Saccharomyces.
