All real foods in the table above have at least one red/amber traffic light warning and olives and cheese have three. The former being a good source of natural fat – especially the much eulogised mono-unsaturated fat – and the latter being an excellent source of calcium and the other bone nutrients vitamin D and phosphorus.

With one exception, all processed foods in the table above have green lights for fat, saturated fat and sugar. Multi grain bread gets an amber for fat content – because of the highly nutritious seeds that is contains. White bread scores better than multi grain.
