Yes, type 2 diabetes is largely caused by poor diet. Diets high in refined carbohydrates, such as white bread, pasta, and sugar, can increase the risk of type 2 diabetes. Eating too much of these foods can cause the body to become resistant to insulin, the hormone that regulates blood sugar levels in the body. This can lead to an increase in blood sugar levels, which can lead to diabetes.
Foods that are high in saturated fats, such as red meat, fried foods, and processed foods, can also increase the risk of type 2 diabetes. Eating too much of these foods can cause the body to become resistant to insulin, leading to the same result as eating too many refined carbohydrates.
In addition to poor diet, other risk factors for type 2 diabetes include being overweight or obese, having a family history of diabetes, and leading a sedentary lifestyle.
The best way to prevent type 2 diabetes is to maintain a healthy diet that is low in refined carbohydrates, saturated fats, and sugar and to maintain a healthy body weight. Additionally, regular physical activity can help to reduce the risk of diabetes.
