“If you don’t eat much sugar, you can’t develop diabetes.” It sounds logical, but it is not that simple.
Diabetes is often reduced to one idea: eating too much sugar. While diet can influence blood glucose and the risk of developing type 2 diabetes, diabetes is a complex condition influenced by several factors.
Understanding those factors can help us move away from myths, blame and oversimplification and towards better prevention.
First, what is diabetes?
Diabetes is a chronic condition in which blood glucose, or blood sugar, becomes too high. Glucose is an important source of energy for the body. Insulin, a hormone produced by the pancreas, helps glucose move from the bloodstream into cells so it can be used for energy.
In type 2 diabetes, the body does not use insulin effectively and, over time, may not produce enough insulin to maintain healthy blood glucose levels.
This can cause blood glucose to remain elevated.
So, does eating sugar cause diabetes? Not by itself.
Eating foods or drinks high in added sugars can contribute to an unhealthy diet and may make it easier to consume excess calories. Over time, this can contribute to weight gain and increase the risk of type 2 diabetes.
But it is important to note that type 2 diabetes is not caused by sugar alone. A person’s risk is influenced by a combination of genetic, biological, lifestyle and environmental factors. Blaming diabetes on one food or one habit can make the condition seem much simpler than it really is.
What can increase the risk of type 2 diabetes?
Family history
Having a parent, brother or sister with type 2 diabetes can increase your risk. Genetics can influence how the body regulates blood glucose, although having a family history does not mean that you will definitely develop diabetes.
Physical inactivity
Regular physical activity helps the body use glucose more effectively. Being physically inactive is associated with a higher risk of developing type 2 diabetes.
Overweight or obesity
Having overweight or obesity can increase the risk of type 2 diabetes, particularly when excess body fat affects how the body responds to insulin. However, diabetes can also occur in people who are not overweight. Body size alone does not determine whether someone will develop diabetes.
Age
The risk of type 2 diabetes generally increases with age. However, type 2 diabetes can also occur in younger adults and, increasingly, in children and adolescents.
Previous gestational diabetes
Women who have had gestational diabetes during pregnancy have a higher risk of developing type 2 diabetes later in life.
Other health factors
Certain health conditions and metabolic factors can also increase risk. This is why understanding your individual risk is more useful than judging your risk based on one habit or one characteristic.
What about the food we eat?
Food still matters. A healthy eating pattern can support healthy blood glucose levels and help reduce the risk of type 2 diabetes.
Rather than focusing only on whether a food contains sugar, it is useful to consider the overall quality of your diet.
A balanced eating pattern can include:
- Vegetables and fruits
- Whole grains and other high-fibre foods
- Beans, peas and other legumes
- Nutritious sources of protein
- Healthy fats in appropriate amounts
It is also helpful to limit excessive intake of foods and drinks high in added sugars, unhealthy fats and excess calories.
The goal is not to fear sugar or completely eliminate every food that contains it.
The goal is to build eating habits that support your overall health.
What can you do to reduce your risk?
You cannot change every risk factor. You cannot change your age or family history, for example.
But there are steps that can support better health and may reduce the risk of type 2 diabetes.
- Move your body regularly
- Regular physical activity can help improve how your body uses glucose and supports cardiovascular health.
- Choose activities that are realistic for you and that you can maintain consistently.
- Eat a balanced diet
- Focus on the overall pattern of what you eat rather than blaming one food.
- Include a variety of nutritious foods and limit excessive intake of added sugars and highly processed foods.
- Maintain a healthy weight where appropriate: For people who have overweight or obesity, losing even a modest amount of weight can provide health benefits and reduce the risk of developing type 2 diabetes. This does not mean that every person needs to lose weight.
- Avoid tobacco: Not using tobacco supports overall health and can help reduce the risk of cardiovascular complications associated with diabetes. Know your risk and get appropriate checks
You cannot always tell what is happening with your blood glucose simply by how you feel.
Prediabetes and type 2 diabetes can develop with few or no obvious symptoms. If you have risk factors or have been advised to have your blood glucose checked, speak with a qualified healthcare professional about appropriate testing.
Don’t turn diabetes into a blame game Someone developing diabetes does not mean they simply “ate too much sugar” or “didn’t take care of themselves.”
Health is influenced by many factors, including genetics, environment, access to healthy food and opportunities for physical activity. Understanding this does not remove personal responsibility. It simply gives us a more accurate and compassionate understanding of health.
Take Home
- Sugar is only one part of a much bigger picture.
- Type 2 diabetes is influenced by multiple factors, including family history, age, physical activity, body weight and overall health.
Instead of asking:
“How much sugar do I eat?”
ask:
“What is my overall health pattern, and do I know my risk?”
Prevention begins with understanding.
Know your risk. Make informed choices. Get appropriate health checks.
