More than half of half of people said they would follow dinner with Christmas pudding, with 23 per cent planning to have dollop of cream. Between meals, 40 per cent said they snacked on nuts and 30 per cent on crisps, both of which are often contain added salt.
A third of people will eat at least one mince pie, and over half enjoy chocolates throughout the day. Combined with overindulgence at mealtimes, sweet snacks bring the average person's Christmas day sugar intake to the equivalent of 32 teaspoons.
The British Heart foundation has warned that the average person in Britain could consume the equivalent of half a pack of lard in saturated fat, and as much salt as would be found in 50 packets of crisps on Christmas Day.
In a survey, the charity asked 2,000 people who celebrate Christmas what they eat and drink over the festive period. For many people, the Christmas indulgence starts before the turkey is even in the oven, it found.
Stomach cancer is difficult to treat successfully because most cases are not caught until the disease is well-established.
This places even greater emphasis on making lifestyle choices to prevent the disease occurring in the first place - such as cutting down on salt intake and eating more fruit and vegetables.
Because around three-quarters of the salt we consume is already in processed food when we buy it, WCRF would like to see traffic light labelling on the front of food and drink packaging to give clear guidance on the levels of salt as well as sugar, fat and saturated fat.
