The meals which scored the lowest were a breakfast set of eggs, sausages and instant noodles, and lunch sets of chicken curry rice and baked pork chops with rice.

In general, the samples were found to have a high calorie count, which can cause obesity.

They were also low in fibre, which can lead to constipation. The low amount of calcium in these meals could also cause osteoporosis.

The council urged restaurants to serve foods high in dietary fibre, such as vegetables, fruits and cereals.

Meanwhile, the council tested 12 battery chargers and found that they did not work as well as they claimed to do.

Nine of the 12 chargers performed at varying speed, taking between less than one hour to more than six hours to recharge AA and AAA-type batteries.

The council advised consumers to buy chargers with a 'cut-off' feature, as they can determine when batteries are fully charged by reading their voltage or using a timer.

And in a survey on digital cameras, three Cannon models scored the highest marks.

The council sampled 19 current models with an output resolution ranging from 3.1 million pixels to 6.3 million pixels.

Most produced satisfactory marks. The cameras were rated on picture and movie quality, flash performance, battery life, versatility, ease of use and viewfinder or monitor quality.
