The bigger your supermarket, the bigger you are

They say ‘you are what you eat’, but is it actually a case of ‘you are where you shop’?

New research has shown that while we’re piling food into our trolleys, we could be piling on the weight – and larger supermarkets could be to blame.

While us shoppers love the convenience of having a big, one-stop shop, two recent studies have examined the link between how often we go shopping and the healthiness of the food we buy.

Evidence suggests supermarket size prompts us to shop less often and buy more on each trip. Could the sheer size of our shops be making us fat?

Forget Texas, in Australia we like everything big from our liquor superstores to Costco to shopping centres.

A recent study of eight countries found only New Zealand and the United States had bigger supermarkets than Australia, and those two countries also have a higher prevalence of obesity than Australia.

There was an almost-perfect connection between how big a country’s supermarkets were and the number of obese people in that country.

Shopping less often and buying less healthy foods on that shop, i.e. doing bulk runs, suggests store size is part of the issue. that and if we do larger shops but then run out between shops, we also can allow ourselves have more takeaways as a sort of reward.

Suggested ways to make the bulk shopping trip to a large centre a healthier one is to walk and catch public transport, use more local businesses, and have better presentation of healthier foods in supermarkets.

If you shop somewhere that offers you everything, consider making more frequent trips and planning healthy meals.
