Now, chocolate aficionados will not have to think twice before indulging in their favourite treat, for Cadbury Schweppes is planning a new range of low-sugar sweets and chocolates including Dairy Milk Lite in consideration of the changing tastes of health-conscious consumers.
In addition, the company is on the brink of launching low-calorie versions of its Maynards Wine Gums and Bassetts Allsorts with half the sugar and 30 per cent fewer calories than in a standard packet.
The company hopes that these will be a predecessor, of what will become the "Holy Grail" of sweet makers, a low-calorie chocolate bar that tastes no different to a normal milk chocolate.
"We have scientists in laboratories working on it. It is the Holy Grail of all chocolate manufacturers," The Telegraph quoted Tony Bilsborough, from Cadbury, as saying.
The markets for low-calorie chocolate have grown across Europe as young women, particularly, try to decrease their calorie intake, but are not prepared to put a curb on snacks.
The low-sugar market in chocolate has experienced a boost by 52 per cent in the past five years, according to the market research company Euromonitor.
It stands at 70.6 million pounds and is expected to reach 100 million pounds by 2010, though this represents less than one per cent of the total chocolate market.
Cadbury has already taken a step forward, with its launch of Cadbury Highlights last year. It has 160 calories compared to the equally sized Dairy Milk, with 255 calories.
Bilsborough said that it would take some time to make the critical advance of creating a low-fat bar that had the same, soft texture of normal milk chocolate.
A launch of Dairy Milk was "probably years, rather than months away", he said.
While Cadbury works on the low-fat chocolate, it is launching a series of low-sugar sweets to tap in the booming market, which has taken off far more rapidly than the low-calorie chocolate market.
Cadbury is growing its research and development investment from 78 million pounds a year to 126 million pounds by 2009.
