More processed foods have been found to contain high levels of salt and/or fat, according to a study by Consensus Action on Salt and Health (CASH).

More than 200 chilled dips sold in supermarkets were tested, including houmous, taramasalata, salsa and guacamole. Houmous has a high calorie count of 280 per 100gm, and the tastiest products, caramelised onion houmous from Marks and Spencer and Tesco contained more salt per 100gm than four packs of ready-salted crisps. A portion of Waitrose cheese and chive dip contained more fat than a McDonald’s Big Mac.
