High-Sugar Foods and Drinks
The main restriction for people with diabetes is food and drinks with added sugar. Candy, cake, cookies, donuts, and sweet jams contain simple sugars that are digested quickly, immediately triggering blood sugar spikes. Excessive consumption also overworks the pancreas and triggers insulin resistance, especially in type 2 diabetes.
Sugary drinks are even riskier because sugar in liquid form is absorbed faster. One can of soda can contain more than 30 grams of sugar. The same applies to sweet tea, bubble tea, energy drinks, and packaged fruit juices that often contain added sugar and lack the fiber of whole fruit.
White Carbs and Processed Foods
Not all carbohydrates must be avoided, but refined carbs should be limited. White rice, white bread, pasta, and noodles are made from white flour that is low in fiber, so they break down into glucose quickly. Instead, choose brown rice, whole-wheat bread, or sweet potatoes, which are digested more slowly.
Ultra-processed foods such as sweet cereals, instant meals, and frozen foods are generally high in sugar, refined starch, fat, and sodium while being low in fiber. Processed meats such as sausages, corned beef, and bacon should also be avoided because they are high in fat and sodium, which can impair insulin sensitivity.
Saturated Fat, Fried Foods, and High-Fat Dairy
Foods high in saturated fat can increase the risk of obesity and insulin resistance, worsening diabetes. Limit fatty meat, chicken skin, butter, and high-fat cheese. Fried foods such as french fries and battered fried chicken are also high in fat and calories, keeping blood sugar elevated for longer.
For dairy products, choose skim milk and low-fat yogurt and cheese. Limit full-cream milk, ice cream, and high-sugar yogurt. Dried fruits and canned fruits in syrup should also be avoided because they are high in sugar, while fresh whole fruit is generally safe in reasonable portions.
Plan Your Diet with an Expert
Avoiding restricted foods alone is not enough; people with diabetes still need balanced nutrition. Healthy protein can come from skinless chicken breast, grilled or boiled fish, tofu, tempeh, and legumes. Boiled, steamed, or soup-based vegetables are far better than fried ones or those served with fatty sauces.
Every patient has a different condition, so the ideal diet can vary. Consult a doctor or nutritionist to plan a suitable daily menu, and monitor blood sugar regularly to keep it under control.
