Recommended Diet for Diabetics on Insulin: How to Plan Balanced Meals

The Relationship Between Diet and Insulin

Insulin plays an important role in blood sugar regulation by helping glucose move from the blood into cells to provide energy for the body. People with type 1 diabetes have little ability to produce insulin on their own, while people with type 2 diabetes often suffer from decreased insulin sensitivity. Since carbohydrates are broken down into glucose during digestion, their intake, food composition and meal times all affect post-meal blood sugar levels and the body's demand for insulin. Therefore, reasonable diet planning is an important part of insulin treatment. Keeping track of carbohydrate intake can help patients who require mealtime insulin to plan their medication according to their meals.

Why Do Insulin Users Need Regular Meals?

Insulin can lower blood sugar, while foods containing carbohydrates can raise blood sugar. Therefore, having regular meals and coordinating meal times with the effect of insulin can help maintain stable blood sugar. If you delay eating or skip a meal after injecting pre-meal insulin, your blood sugar may drop too low. Common symptoms of hypoglycemia include shivering, sweating, hunger, and confusion. People using fixed-dose or premixed insulin usually need to maintain relatively regular meal times and carbohydrate intake. People who use the flexible mealtime insulin regimen can adjust the dosage according to their carbohydrate intake and blood sugar levels. People using only basal insulin need to combine specific doses, other hypoglycemic drugs, and individual blood sugar changes to arrange their diet. When planning meals, you can use the carbohydrate counting method or use the plate method to reasonably combine vegetables, proteins, and carbohydrates. If the insulin dosage needs to be adjusted according to the carbohydrate intake, accurately estimating the carbohydrates in food is particularly important.

How Carbs Affect Blood Sugar?

During the digestion process, the body breaks down sugar and starch in food into glucose, which enters the bloodstream to provide energy for the body. After carbohydrate intake, blood sugar levels rise, and insulin helps glucose enter cells. When the body is unable to produce enough insulin or the cells' response to insulin weakens, blood sugar regulation will be affected. The changes in postprandial blood sugar not only depend on the intake of carbohydrates, but also are related to the types and composition of food. Each person's specific needs vary depending on their physical activity level, medication use, nutritional status, and blood sugar targets. It is recommended to develop a diet plan suitable for oneself under the guidance of a doctor or registered nutritionist. Through regular blood sugar testing or continuous glucose monitoring, the actual impact of different foods and meals on blood sugar can be understood. Patients who use insulin during meals should also follow the carbohydrate-insulin ratio plan formulated by the medical team and consult professionals before making significant dietary adjustments.

A Balanced Diet Is Suitable for Food

High-Fiber Carbohydrates

High-fiber carbohydrates not only provide energy for the body but also supplement dietary fiber and other important nutrients, which helps diabetic patients manage their blood sugar better. Whole grains and legumes are the foods that should be prioritized in daily diets. Whole grains retain the bran and germ of grains, while legumes combine dietary fiber and plant protein. The recommended daily intake of dietary fiber for adults can be approximately 14 grams for every 1000 kilocalories of energy consumed, which is about 28 grams in a daily 2000 kilocalorie diet plan. For people who need to increase their intake of dietary fiber, it is recommended to gradually adjust their diet and ensure adequate water intake to reduce digestive discomfort such as bloating.

High-Quality Protein

Protein helps maintain muscles and repair body tissues, and is an indispensable nutrient in a balanced diet for people with diabetes. Good sources of protein include fish, skinless poultry, tofu, and beans, etc. Salmon, sardines, and trout are not only rich in protein, but also Omega-3 fatty acids, and cooking them, such as baking, grilling, or steaming, can help reduce your intake of extra fat. The saturated fat content of skinless chicken and turkey breast is usually lower than that of the skin-covered parts. Choosing meat without coating with flour can also help avoid the intake of additional carbohydrates. Tofu is made from soybeans and contains all nine essential amino acids, which can be combined with vegetables to make stir-fries, soups, and other meals. Beans and lentils are both rich in protein and dietary fiber, but since they also contain carbohydrates, they should be included in the total carbohydrate intake when planning meals.

Non-Starchy Vegetables

Non-starchy vegetables are rich in dietary fiber, vitamins and minerals, and have relatively low carbohydrate content, making them suitable for inclusion in the daily diet of people with diabetes. Spinach, kale and romaine lettuce can be used to make salads, soups or stir-fries. Broccoli, after being steamed or baked, can retain good texture, while roasted cauliflower or chopped cauliflower can add flavor to the dish. Fresh, frozen and canned vegetables can all be part of the daily diet. Choosing regular frozen vegetables or canned vegetables labeled "no added salt" can help reduce additional sodium intake. Washing canned vegetables can also remove some sodium. During cooking, a small amount of olive oil can be used for steaming, baking or stir-frying vegetables, and seasoned with herbs, spices or lemon juice. In contrast, coating with batter, sweet sauces and thick sauces may increase carbohydrate, fat or sodium intake. Therefore, it is necessary to control the amount.

Moderate Intake of Healthy Fats

Diabetic patients can consume an appropriate amount of unsaturated fats in a balanced diet to support heart health. Nuts, olive oil, and avocados are all good sources of unsaturated fats, but since fat provides about 9 kilocalories per gram, you need to be careful about portion size. Nuts and avocados also contain dietary fiber, which helps promote digestive health. Diabetic patients should be cautious about limiting the intake of saturated fats to maintain cardiovascular health. When cooking daily, you can use olive oil instead of butter and avocado to replace some of the high-saturated fat sauces in sandwiches, so as to more reasonably combine dietary fats.
