Hotdog eating competitions sound like fun in theory, but they are best left to cartoon characters like Homer Simpson. A new study has found that eating fresh foods adds minutes of healthy life each time, but processed* foods take healthy minutes away – placing processed foods like hotdogs firmly in the ‘occasional treat’ basket.

The good news is that a portion of nuts adds almost 26 minutes a serve, while every banana brings a boost of almost 14 minutes, so fresh foods help us to fight back.

The findings come from scientists at the University of Michigan in the US, who evaluated* more than 5800 different foods on their nutritional value and the amount of carbon* needed to produce them.

The study’s Health Nutritional Index calculated the impact of various meals, snacks and drinks. Researchers found that swapping as little as 10 per cent of a person’s diet from processed meats to natural, fresh foods like nuts, fruit and vegetables could add as much as 48 minutes of healthy life a day. Researchers said this simple change also had clear environmental benefits, slashing a person’s daily dietary carbon footprint by a third.

media_cameraHotdogs are a popular treat for adults and children alike, but with research suggesting each hotdog costs about a half-hour of healthy living, this amusement park favourite should be kept for special outings and occasions.

The humble but highly processed hotdog did not perform well in the study, with each hotdog taking the equivalent of more than half an hour of healthy life.

“The 61 grams of processed meat in a hotdog sandwich results in 27 minutes of healthy life lost due to this amount of processed meat alone,” the study authors said.

“Then, when considering the other risk factors, like the sodium* and trans fatty acids* inside the hotdog – counterbalanced* by the benefit of its polyunsaturated* fat and fibres – we arrived at the final value of 36 minutes of healthy life lost per hotdog.”

But does that mean a lifetime ban on the best things in a bun? No – but the results reinforce something everyone already knows: treats like hamburgers, hotdogs and soft drinks are not something anyone should be eating or drinking every day.

The study, published in the journal Nature Food, is based around healthy life expectancy, which is the length of time a person has a good quality of life and lives disease-free.

“The urgency of dietary changes to improve human health and the environment is clear,” said Professor Olivier Jolliet, the study author.

“Our findings demonstrate that small targeted substitutions offer a feasible* and powerful strategy to achieve significant health and environmental benefits without requiring dramatic dietary shifts.”

Cheeseburger Case Study media_cameraScout Parker, 2, and his brother Courtland, 4, enjoy the occasional cheeseburger, but mum Erica Parker said that she makes sure the majority of their diet is healthy. Picture: David Swift.

For Sydney mother-of-two Erica Parker, the results were no surprise. She said making healthy choices was always a priority when feeding her two sons, Scout, 2, and Courtland, 4.

“Courtland had never really had a burger until my second pregnancy,” she said. “I found it a lot harder to cook with him and keep up with healthy eating during this time. So now it’s been a bit more challenging trying to redirect him to healthier options.”

“My other son Scout makes it easier by being incredibly fussy, so we can pick and choose healthy options.” Ms Parker said

But on special occasions, or when the family is short on time, her children still enjoy a cheeseburger.

“However, they do prefer chicken burgers over beef and bacon,” she said.

In fact, stepping away from red meat is something the Parkers share with many other families, including former meat eaters the Ekstroms, with a dramatic shift in how often the average Australian eats meat, with just one in five now eating meat daily. Nicole Ekstrom and husband Henrik made the move to veganism nearly five years ago and she describes her two children Lynn, 11, and Nils, 9, as “flexitarian” – or mainly vegetarian, with occasional meat and other animal products.

”Flexitarianism” is on the rise, with a poll of 1026 Aussies conducted by research firm Toluna finding no significant spike in people becoming vegan or vegetarian, but big shifts among meat-eaters in the amount of red and white meat they eat per week.

One in four respondents said they had already cut back and a further 19 per cent were planning to do so.

Health was the primary driver of the trend. Of those reducing their meat intake, 65 per cent said they were doing so for health reasons, 40 per cent said the high cost of meat was prompting their decision, and 30 per cent said they were motivated by environmental reasons.

But other surveys suggest Australians exceed recommendations for meat eating. ABS data from December, for example, showed that Australians were eating an average of 142.5g of meat and poultry products every day, or almost exactly a kilogram per week, despite the Cancer Council and other health organisations saying we should eat a maximum of 455g of lean, cooked red meat per week.

Meat was a nightly staple for most Australian families last century, but the Toluna survey found one in five people (20 per cent) said they now ate meat every day. Forty-two per cent of respondents said they aimed for one or two meat-free days per week, 24 per cent go without it three or four days per week, and 8 per cent keep themselves vegetarian for five or six days per week. Just 6 per cent said they never eat meat at all.

One in four respondents to the Toluna survey said they had tried plant-based protein alternatives, and of those, two in three said they would eat them in future.
