I don’t buy crisps and hardly ever feel like eating them but put me in front a bowl of them and I can’t help myself! It’s even worse with a glass of wine and a few friends around. The ambiance, the conversation… before I know it I’ve mindlessly gobbled up hundreds of kilojoules and a few good spoonfuls of fat. It’s all to do with proximity.

So if it works with crisps, why not vegetables? This is the question that researchers at Cornell University recently answered with a resounding YES. Move the salad bar so it’s more ‘in your face’ and the kids eat more salad. Such a simple move, and not a mention of 5-a-day, antioxidants or any other cleverly crafted health coercement (not sure if that is a word but it sounds good!)

But hold on, don’t us mums already do that at home? We innately understand proximity. We chop an extra carrot, a few extra vegetables and pop them in front of the kids to allay the pre-dinner whining. We chop up fruit and put it on the table – and it gets eaten. If we told our kids to go eat an apple or a carrot, they would hardly jump at the idea. But when it’s placed in front of them most kids gladly eat it – especially if there’s nothing else on offer. I’ve found it works with husbands too.

So before the researchers and big business spend any more millions on working out how to get kids to eat their food, perhaps they could leave work early and see how it’s done in their own home!
