A report stated that there are dangerous levels of sugar and salt along with fat in Chinese and Indian takeaways across the country.

Compared to a person’s daily recommended limit of saturated fat, a portion of chicken tikka masala contained about 116 per cent of saturated fat and the salt content was about 92 per cent.

Sugar content in Cantonese sweet and sour chicken with fried rice had about 75 per cent of the recommended daily limit of sugar, about 16 teaspoons and the salt content was 119 per cent of the recommended limit.

The limit set by the Food Standards Agency guidelines is 70g of fat everyday and about six grams of salt.

Food colourings found in one in five sauces was more than the set legal limits.

A more comprehensive study is needed to figure out the amount of artificial colourings in chicken tikka masala sauce.

Staff was told by about 36 of the restaurants testers that they suffered from nut allergy and their takeaway should not contain nuts.

One out of five takeaways was seen containing nuts like peanuts or almonds and this can be fatal for someone who suffers from nut allergy.

The report said, “Local authorities should ensure further work with these ethnic kitchens to reduce the occurrence of providing such false information.”
