A Chinese takeaway can contain the equivalent of a wine glass full of lard, a study has found.

A meal including prawn crackers, crispy duck, chicken balls and spring rolls includes 2,823 calories and 132.5 grams of fat – the equivalent of a small wine glass. The average takeaway overall includes around 1,500 calories.

Women are advised to limit their calorie intake to 2,000 a day and men to 2,500. The nutritionist Mary Strugar said: "Takeaways as an occasional treat are fine. However, when such high volumes of fat and calories, not to mention salt levels, are consumed on a more regular basis you are in serious danger of putting your health on the line."
