SOME ready meals are “crammed” with salt and fat, a consumer group warns today.

Which? found huge variations in recipes for different pizzas, curries and lasagnes sold in supermarkets.

Some popular dishes contained five times more fat and four times more salt than the healthiest versions.

But the product packaging doesn’t always make it obvious to shoppers what they are eating, Which? said.

The consumer group is calling for all manufacturers and retailers to add traffic light labels to their products to indicate levels of fat, sugar and salt.

Nearly a third of shoppers buy a ready meal at least once a week, pushing sales to about £2bn per year.

Which? chief policy adviser Sue Davies said, “Going to the supermarket for a ready meal has become a lucky dip, as some manufacturers are still insisting on cramming their meals with salt and fat, without making it obvious for shoppers what they’re really eating.”

The highest amounts of fat, saturated fat and salt per 100g were all found in cheese and tomato pizzas.

Dr Oetker ristorante pizza mozzarella was the highest in fat at 14.4g per 100g.

Tesco deep crust pizza cheese feast was highest in saturates at 7.9g per 100g.
