One of the UK’s biggest supermarket chains is planning to spy on the shopping habits of customers who want to slim and advise them on how to eat more healthily.

Tesco will use data from its loyalty card scheme to see who is loading up on high-calorie or fat-laden food such as doughnuts, chocolate and pizza.

Its 16 million Clubcard members could then be offered vouchers for healthier products or given recipes as part of the battle against the growing obesity epidemic. Tesco boss Philip Clarke said customers would need to ‘opt in’, rather than being bombarded by unwanted suggestions.

‘We won’t encourage healthier lifestyles by editing choices, but we can influence choice by making healthier options,’ he told The Grocer magazine. The supermarket’s technology experts have built an online tool – dubbed the ‘healthy little differences tracker’ – that will measure how customers’ habits change following the health drive.

The group is also expected to contribute data to government research into obesity.

However, only anonymous data will be passed to health research organisations, unless customers volunteer their details.

New York City’s campaign to cut consumption of sugary drinks now features ads warning people about sweet teas, sports and energy drinks and fruit-flavored beverages.

The city health department launched the TV and bus ads Monday. The spots say such drinks might sound healthy but are packed with added sugar and that can lead to obesity and other health problems. Some of the ads target kids and teens.

Instead, the health department urges residents to drink fat-free milk, seltzer or water and eat fresh fruit instead of drinking juice.

The ads cost about $1.4 million. They further a “pouring on the pounds” campaign that dates to 2009.
