Eating at home may reduce food wastage: study

Press Trust of India  |  Washington 

at home may lead to less wastage as compared to out, according to a first of its kind study that followed daily habits of adults.

The same people who on average left just three per cent of their on their plates when choosing their own meals, left almost 40 per cent behind when given a standard boxed-lunch type of meal.

Plate waste at home was 3.5 per cent higher when diners went for second or third serving, researchers said.

What we leave behind on our plates is the primary focus of efforts to reduce waste, and this study shows that it is potentially more important to concentrate on other conservation measures at home, including using up food before it spoils, said from The in the US.

Prior research typically has focused on "plate waste" in settings such as school cafeterias and buffets and has found much greater waste - from about seven per cent at an all-you-can-eat pizza buffet to 18 per cent waste of French fries at an all-you-can-eat university hall.

The new study, published in the journal PLOS ONE, is the first of its kind to follow adult eaters through their normal day-to-day patterns, said Roe.

"This study allows us to go into the daily eating habits of adults and suggests that when people are choosing their own food, there's not a lot left on their plate," he said.

The researchers tracked through pictures the 50 study participants took on before and after meals. The study ran for about a week and included all meals eaten at home or away from home.

To compare plate waste in a controlled environment versus a home environment, the researchers had participants dine twice in a lab setting - on lunches that included a lunch meat sandwich, cookies, pretzels, a fruit cup and a of the diner's choice.

Based on this study, it is probably more important to focus on meal planning and using up foods (and leftovers) before they spoil than on what is left on the plate at home, Roe said.

"Better meal planning is a good place to start. Coming up with a recipe for the leftovers that your family and your kids will actually eat is the next step," Roe said.

of the in Louisiana, said that the negative effects of being provided with too much food or serving yourself too much are becoming more apparent.

"When this happens, people are much more likely to have a lot of plate waste after their meal," he said.

Roe and his colleagues are developing a phone app designed to track They will soon begin testing the "Food Image" app in a pilot project.
