Look familiar? Sugar-free, low-fat, healthy, lite, natural, low kilojoule, free range, and the list goes on. This is just on the front of food packages then there is a mound of information on the back as well.
Companies use these slogans and phrases to make you believe that their food is healthy, better than other brands, good for you, and will give you everlasting energy. It’s called marketing. A number of these claims have some truth in them but can be very misleading, confusing, and have even been known to be unsubstantiated. Do not rely on the front of the package only. The back nutritional label and ingredient list are far more informative.
Why is it important to be able to read and understand food labels?
Well, labels give information allowing you to make informed, healthier food choices that will impact not only on glucose management but weight, cholesterol, and overall health. It empowers you, the consumer.
Nutritional label and ingredients
One of the main nutrients people living with diabetes need to be aware of is carbohydrates. These are the nutrients that cause elevation of blood glucose levels. This is not a bad thing. A carbohydrate (carb) is a sugar molecule made-up of starch, sugar, and fibre. These will be converted into glucose as energy for the body.
Fibre is a non-digestible carbohydrate and therefore has no effect on blood glucose levels. As a matter of fact, if the fibre content is >5grams this can be subtracted from the total carbohydrate amount. The more fibre, the better. It’s the total amount of glycaemic carbohydrates/carbohydrates to be considered when making food choices, not the sugar content.
Key pointers
Whilst perusing the nutrition label and ingredients there are key pointers to keep an eye on.
Serving size
On a nutrition label, there are usually two columns showing nutritional information, one for 100g and one for an individual serving of the product. The product package size is not necessarily the serving size. If a package says low kilojoule, it may be because the serving size listed is very small and unlikely that someone would only have a single serving.
As a South African, you surely know Romany Cream biscuits. The serving size is two biscuits. There are very few people I know who only have two biscuits. The small jelly sweets or gums sold in 75g bags are in fact three servings of 25g each. So, in future, please remember the packet should be spread over three days.
A certain South African brand of flavoured water contains 4g of carbohydrates per 100ml and 62,76kJ. That means 20g of carbohydrates and 313.8kJ per bottle of water.
The label may list that you will be eating a certain percentage of a daily recommended amount of nutrients or kilojoules based on an 8368kJ diet. Remember to multiply by number of servings. Not everyone should be consuming 8368kJ a day.
Ingredients
Ingredients are listed in descending order by weight, meaning the first ingredient is the largest amount of the product. Some foods have a boundless list of ingredients.
It’s safe to say, the fewer ingredients, the more natural and less modified a food is. If a product claims to be whole wheat, then whole wheat must be the first ingredient listed. Anything on the ingredient list means it has been added in the production of the food item.
“Sweets for my sweet, sugar for my honey” come in many disguises. Sucrose, corn syrup, fructose, maple syrup, molasses, and nectar are all forms of sugar. The list of sugars is endless. The names of many sugars end in -ose.
Caffeine can also be masked in the ingredient list. Guarana commonly used in energy drinks is high in caffeine, but it’s not always added to the total caffeine amount.
Ingredients necessary to give colour, thickness, anti-caking agents, gelling, and preservatives are some food additives categorised by E numbers. E249 – E250 indicate the use of nitrites. The less of these consumed, the better.
Substitutes
Manufacturers want their food to taste good and appear healthy. This can be done by using substitutes so that the labels low-fat or sugar-free can be used. These claims may be true, but to replace the sugar and fat, other ingredients are added to maintain flavour, very often salt or sugar (to low-fat).
Checking salt (Na) is important as this should be avoided in people with hypertension. Sugar substitutes and artificial sweeteners have been linked to an increase in appetite in some studies. This defeats the object.
Laws
International laws are changing to make labels more user friendly and less misleading. Traffic light colour coding is currently used in the UK. Red means high, amber means medium, and green means low. These are for fat, saturated fat, sugar, and salt. This system allows you to see at a glance which is a healthier option. Helpful for people with low numeracy and literacy
In 2023, the South African Department of Health drafted new restrictions on food marketing, food labelling, and health claims on packaged food and drink. Hopefully, it will be law soon. In our multi-cultural country with eleven official languages, it’s sad that our food labels are written in English only.
