Most of us have great faith in numbers, especially ones that are boldly printed in black and white on labels and in books. But a number of studies suggest that if you want to count calories (kilojoules) or need to count your carbs, you also need to be aware that the numbers you see printed aren’t precise figures at all. They are just ballpark figures. ‘It’s a fact of life that even the most processed of foods never contain the exact amount of carbohydrate in a serve that the label says while the figures given in food tables will be average or typical not precise amounts. So, don’t get too carried away thinking that by counting every gram of carbohydrate you eat or drink and every 0.05 of a unit of insulin you take your blood glucose levels will be perfect,’ writes Dr Alan Barclay in Food for Thought. ‘It just doesn’t happen like this.’
