According to this article some supermarket salads contain more fat and calories than you would find in a Big Mac and fries. The consumer group Which? looked at a number of salads on sale in supermarkets. It founds that a Smedleys Atlantic prawn marie rose salad from Morrisons contained 855 calories and 66.3g of fat. A Sainsbury’s tomato and basil chicken salad also had a high fat content with 27.7g of fat and 595 calories. In comparison a Big Mac and medium fries contains 820 calories and 40g of fat. The reason for the high fat content of most of the salads was the fact that they contained a large amount of mayonnaise, creamy sauces or pasta all of which are high in fat.
