Sugar Free vs No Added Sugar, What’s Better?

In recent years, there has been an increase in food awareness. People have now started to read food labels in an effort to make healthier food choices. However, nutrient claims on food packaging can be a little confusing, and sometimes deceiving if clever marketing strategies are used. A popular health claim on food packaging is, Sugar Free vs No Added Sugar, so what’s the difference?

Thankfully, nutrient claims about sugar on food labelling have now become regulated by the Food Standards Code. This means a product must meet a certain criteria before it can use a health claim on its label. However, the wording in health claims can be confusing and it’s possible that food companies will use clever marketing ploys to sell their products. Often, consumers will focus on catchy health claims on the front label, however, in order to make an informed decision, it’s more important for you to know how to read nutritional labels on the back of the product. Thus, the goal of this article is to give you quick and easy tips for reading the nutritional label, so in the future, you can potentially avoid dental decay related to sugar.

Let’s Define Sugar Free vs No Added Sugar

Sugar Free

This means a product contains less than 0.5 g of sugar per serving. These products frequently use artificial sweeteners, such as sorbitol, xylitol or erythritol to sweeten a product without adding sugar or additional calories/kilojoules.

No Added Sugar

If a product claims to have ‘no added sugar’, then that doesn’t mean it is sugar free. It simply means that the manufacturer has not added any additional sugar during the processing or packaging of the food. These products are often sweetened by natural sugars (ie. naturally occurring sugars from fruits), and these fruits will be listed in the ingredient section on the product label. It’s important to check the nutritional label, so you can avoid products which have “Added Sugars”.

Free Sugars

These are a type of “Added Sugar”, because they have been extracted from the cells of fruits and vegetables. But in the process, they lose all the good nutrients and fibres. Examples of products with “free sugars” are honey, syrup and fruit juices. These types of products can be misleading because they are often marketed as “naturally sweetened” or “no added sugar”. However, these “free sugars” products behave the same as table sugar. Thus, making them unhealthy sugars for your teeth and overall body.

Moreover, it becomes easier to consume an excessive amount of sugar in the form of “free sugars” without satisfying your hunger. Take for example a glass of orange juice, it has the same amount of sugar as FOUR oranges. However, a glass of orange juice doesn’t satisfy your hunger nor does it give you the same amount of nutrients and fibres as eating 4 oranges. We rarely consume 4 oranges in one sitting, but we can easily drink a glass of orange juice without realising its “Free Sugar” content.

Dentist’s Advice on Sugar

According to various scientific articles, “added sugar” and “free sugars” are a major risk factor for developing dental decay. Therefore, cosmetic dentist, Dr. Sanya recommends all patients to avoid food or drinks with “Added Sugars” or “Free Sugars. However, it can be difficult to determine which foods have “Free Sugars”, because manufacturers tend to combine Natural Sugars and Free Sugars into the same category of “Total Sugars” on a nutritional label. However, a good rule to remember is that raw fruits and vegetables are the best options. The more you process raw fruits and vegetables into juices or purees, the more likely they are to contain “Free Sugars”, which are linked to dental decay.

Dietitian’s Advice on Sugar

Limiting our intake of sugar is important for reducing the risk of chronic disease and maintaining a healthy weight. Frequent intake of refined sugars dramatically increases the risk of developing dental decay, Type 2 diabetes & weight gain. Sugars also add a large portion of calories to our diet without much ‘goodness’ in return. As a dietitian, I prefer foods sweetened by using whole fruits, so we can take advantage of their natural sugars, but also maintain their nutrients and fibre! A great example of a fruit-sweetened treat is banana bread, click here for a delicious dentist-approved banana bread recipe.

  3. Natural sugars found in fruits and vegetables are healthy, but it’s best to eat fruits and vegetables raw. Avoid consuming fruits or vegetables in the form of juices or purees due to their high “Free Sugar” content.
