(Reuters) – Mars Inc., maker of Snickers and Twix, will stop selling chocolate products with more than 250 calories from next year, said a spokeswoman for the firm.

The firm headquartered in Virginia, United States, which also produces the M & M candies and Skittles, said that the goal is part of an effort already under way to improve the nutritional product value and sell them in a responsible manner.

The new limit to the calories contained in their products implies that lovers of the Snickers of extra large size – with 540 calories–have little time to enjoy their precious sweet. Arriving by 2014, is gone, as part of what Mars is considered a boost to the responsible consumption of candy.

In 2007, the private company reported that it would stop buying space and time advertising if more than one quarter of the audience was probably younger than 12.

Mars also said that it will reduce 25 per cent levels of sodium in their products by 2015.

The spokeswoman Marlene Machut said that the plan to manufacture any product chocolate exceeding 250 calories per serving by the end of the 2013 – notified initially during the last autumn – is part of a “strong commitment to the health and nutrition” that has Mars.

Several U.S. media, including national public Radio reported on the reduction of the Mars chocolate bars this week.

Mars is one of the main producers of the food industry worldwide. In addition to candy, manufactures ice cream Dove, and the Pedigree and Whiskas pet food and Uncle Ben rice.
