Make it compulsory for restaurants & manufacturers to supply carbohydrate values

Many diabetics use life saving drugs called insulin to regulate their blood sugar levels. For most using insulin, the number of units givenis worked out based of the amount of carbs consumed.
Whilst many pre packed meals contain this information, it is not currently compulsory.
Restaurant also are not required to supply this information.
Without this information, many diabetics are forced to guess, therefore risking hypoglycemia or hyperglycemia. Both of which can be extremely dangerous.
