FOODS high in fat, sugar or salt are able to make misleading nutritional claims on packaging, consumer groups have warned.

Which? is calling on the European Parliament to approve new rules which would tighten up product labelling.

It says companies do not currently have to prove the accuracy of nutritional claims before goods go on sale.

MEPs in Brussels are to vote this week on new rules which set out when health nutrition claims can be made on food and drink packs.

Which? spokeswoman Michelle Smyth said: "Tighter controls over so-called healthy foods are needed to help consumers make healthier food choices more easily."
