Hamburgers largely sold by McDonald’s, which were considered unhealthy till now, are now being claimed as healthier than BLT brands, says a new report.

It has been told by a team of researchers, which conducted a survey on foods sold by different companies, that those in which the traffic light system is used have healthier foods. As per the team’s say, a traffic light system is used by many companies, which decides if the food is healthy or unhealthy.

As per this system, healthy foods are labelled with green colour and unhealthy foods are labelled with the red one. Also, it clearly tells if the amount of fat, sugars and salt in the chows are low, medium or high.

Some instances were also given by the surveyors, including one of chicken salad sandwich sold by Morrisons and that by Waitrose. While the provided by Waitrose, which uses the system, contained 6g of fat, the salad available with Morrisons that does not use the same system contained 11.7 grams (0.4oz) of fat.

Considering the situation and hoping to reduce the fat and salt amount in each food item, the government has now called up for a consultation on “front of pack” nutrition labeling this week.
