Sugar & Diabetes: Understanding the Connection Without the Confusion.

 ·  2 min read

Sugar and diabetes are often discussed together but there are plenty of misconceptions about how the two are actually connected. Does eating sugar directly cause diabetes? Are all carbohydrates bad? And should everyone be avoiding sugar completely?

The answer is more nuanced than simply “sugar is bad”. Understanding the difference between sugar, carbohydrates and blood glucose can make everyday food choices a lot less confusing.

Sugar, Carbohydrates and Blood Glucose

Sugar is a type of carbohydrate and carbohydrates are an important source of energy for the body. When we eat carbohydrates, our bodies break them down into glucose which enters the bloodstream and can be used for energy.

But not all carbohydrate foods are the same.

Carbohydrates are found naturally in foods such as fruit, vegetables, milk, legumes and wholegrains. They can also be found in foods and drinks with added sugars including soft drinks, confectionery, cakes and biscuits.

The amount and type of carbohydrate can influence how quickly and how much blood glucose rises. Foods containing more fibre, for example are generally digested more slowly and can result in a more gradual rise in blood glucose.

This is one reason why a bowl of oats, a piece of fruit or lentils shouldn't automatically be viewed in the same way as a sugary drink simply because they contain carbohydrates.

Does Eating Sugar Cause Diabetes?

Eating sugar by itself doesn't mean someone will develop diabetes. Type 1 diabetes and type 2 diabetes have different causes, and type 2 diabetes involves factors including insulin resistance, genetics, body weight and lifestyle.

However, regularly consuming large amounts of foods and drinks high in added sugar can contribute to excessive energy intake and weight gain, which can increase the risk of developing type 2 diabetes.

That's why the goal isn't necessarily to eliminate every gram of sugar from your diet. Instead, it's about understanding where your sugar is coming from and making balanced choices.

What Can We Actually Do?

Start by looking at the foods and drinks you consume regularly.

Sugar-sweetened drinks are an easy place to begin because they can add substantial amounts of sugar without providing much nutritional value. Try swapping some soft drinks, sweetened drinks or heavily sweetened coffees for water or unsweetened alternatives.

When buying packaged foods, don't look at the “sugars” number alone. Diabetes Australia explains that total carbohydrate includes both starches and sugars, and that the total amount of carbohydrate can affect blood glucose levels. Checking the ingredients list and nutrition information panel together gives you a better picture of what you're eating.

You can also make simple recipe changes. For example, when baking at home, reducing the amount of added sugar or using an alternative sweetener can be one way to lower the sugar content of a recipe.

Natvia sweeteners can be used as an alternative to sugar in a variety of drinks and recipes. However, replacing sugar doesn't automatically make a recipe nutritionally complete, so it is still important to consider the overall ingredients and portion size.

Overall, Sugar doesn't have a simple “causes diabetes” relationship. Diabetes is more complex than one ingredient or food. Instead of fearing all carbohydrates or trying to eliminate sugar completely, focus on the bigger picture: enjoy a varied diet, prioritise fibre-rich and nutrient-dense foods, stay active and be mindful of foods and drinks high in added sugar.

And if you have diabetes or are concerned about your blood glucose levels, make sure to speak with your doctor or an accredited healthcare professional for advice suited to your individual needs.
