Many people believe that eating sugar directly causes diabetes. This is one of the most common myths surrounding diabetes. The truth is more nuanced: diabetes has different types and causes, and eating sugar alone does not explain why someone develops diabetes.
MYTH vs FACT
MYTH: “Eating sugar directly causes diabetes.”
Eating sugary foods does not automatically cause diabetes. Type 1 diabetes is an autoimmune condition, while type 2 diabetes develops through a combination of factors such as insulin resistance, genetics, excess weight, physical inactivity and other risk factors.
However, regularly consuming excessive amounts of added sugar, particularly through sugary drinks and calorie-dense foods, can contribute to weight gain and obesity. These can increase the risk of developing type 2 diabetes.
FACT: Diabetes has multiple contributing factors
For type 2 diabetes, the body may become resistant to insulin, meaning cells do not respond effectively to insulin. Over time, the pancreas may not be able to produce enough insulin to keep blood glucose within a healthy range. Family history, genetics, physical inactivity and excess weight can all contribute to risk.
This is why it is more accurate to say:
Sugar is not the sole cause of diabetes, but excessive added sugar can be part of an unhealthy dietary pattern that increases type 2 diabetes risk.
“Diabetes is influenced by many factors not simply by how much sugar you eat. Understanding your individual risk factors and building healthier habits can help you make informed choices for better long-term health.”
MYTH vs FACT: Does Eating Sugar Cause Diabetes?
What can you do?
A healthy approach is not about completely eliminating every source of sugar. Instead, focus on balanced meals, sensible portions, regular physical activity and limiting excessive added sugars. Fresh fruits and dairy foods, for example, can contain naturally occurring sugars and are different from foods with added sugars.
If you have a family history of diabetes, prediabetes, excess weight or other risk factors, regular health checkups and appropriate blood glucose testing can help identify problems early.
