Imagine your plate as a palette, and you’re the artist creating a masterpiece of health with every meal. Welcome to the world of a diabetes diet—a vibrant and balanced way of eating that isn’t just for managing diabetes, but is also a blueprint for overall well-being. By focusing on nutrient-packed foods and mindful portions, this diet helps regulate blood sugar levels while keeping you energized and satisfied. Think fresh fruits, crisp vegetables, and wholesome grains, all coming together to make every meal a delicious opportunity for better health.

Why should you consider a healthy-eating plan? If you have diabetes or prediabetes, or simply want to stay ahead of potential health issues, this approach is a game changer. It’s not just about managing blood sugar; it’s about crafting a lifestyle that supports weight control and heart health. Picture working with a dietitian to design a personalized menu that balances your favorite foods with smart choices. Embracing a diabetes diet means enjoying a variety of flavors while steering clear of foods that spike your blood sugar or increase your risk of heart disease. 

A diabetes diet involves choosing the healthiest foods in balanced portions and following regular mealtimes. It’s a nutritious eating plan that emphasizes foods rich in essential nutrients while being low in fat and calories. The focus is on incorporating fruits, vegetables, and whole grains. In reality, this kind of diet is beneficial for nearly everyone.

Why is it important to develop a healthy-eating plan?

If you have diabetes or prediabetes, your healthcare provider will likely recommend working with a dietitian to create a healthy-eating plan. This plan is critical for managing your blood sugar (glucose) levels, controlling your weight, and reducing risk factors for heart disease, such as high blood pressure and cholesterol.

When you consume excess calories and carbohydrates, your blood sugar rises. Uncontrolled blood sugar can lead to serious issues, such as hyperglycemia (high blood sugar), which, if prolonged, may cause complications such as nerve, kidney, and heart problems.

Making healthy food choices and monitoring your eating habits can help you maintain your blood sugar in a safe manner. For many with type 2 diabetes, weight loss also improves blood sugar control and provides various other health benefits. A healthy-eating plan offers a structured and nutritious approach to achieving weight loss goals safely.

A diabetes diet involves eating nutritious meals at regular intervals to improve the use of insulin, either produced naturally by the body or administered through medication. A registered dietitian can help craft a personalized eating plan based on individual health goals, preferences, and lifestyle. This plan may also include strategies for selecting portion sizes appropriate for your activity level and body size.

Recommended Foods

It is important to make calories count by utilizing nutrient-dense foods, including healthy carbohydrates, fiber-rich options, heart-healthy fish, and “good” fats.

Healthy Carbohydrates

Carbohydrates break down into glucose during digestion, which affects blood sugar levels. Opt for healthier sources of carbohydrates such as:

• Fruits
• Vegetables
• Whole grains
• Legumes (beans and peas)
• Low-fat dairy products

Fiber-Rich Foods

Dietary fiber helps to reduce the amount of sugar in the body and control blood sugar. Good sources of fiber include:

• Vegetables
• Fruits (whole fruits rather than juice)
• Nuts
• Legumes
• Whole grains

Heart-Healthy Fish

Eat fish rich in omega-3 fatty acids, such as salmon, mackerel, tuna, and sardines, at least twice a week. Omega-3s can help reduce the risk of heart disease. Avoid fried fish and, if pregnant or breastfeeding, stay away from fish high in mercury (e.g., shark, swordfish).

Good Fats

Monounsaturated and polyunsaturated fats can improve cholesterol levels. Sources of good fats include:

• Avocados
• Nuts
• Canola, olive, and peanut oils

Foods to Avoid

To lower the risk of heart disease and stroke, avoid the following:

• Saturated fats: Found in high-fat dairy, butter, and red meats.
• Trans fats: Present in processed snacks, baked goods, and margarine.
• Cholesterol: Found in high-fat dairy products, egg yolks, and organ meats. Limit intake to 200 mg per day.
• Sodium: Limit sodium intake to 2,300 mg per day or less if advised by a healthcare provider.

In summary, a diabetic diet focuses on balanced, nutritious meals eaten at regular intervals to help manage blood sugar levels, weight, and heart health. Key components include healthy carbohydrates, fiber-rich foods, heart-healthy fish, and good fats, while avoiding saturated and trans fats, cholesterol, and excess sodium. By following these dietary guidelines, individuals with diabetes can effectively manage their condition and reduce the risk of complications, including heart disease and stroke.

Glucose, the body’s main energy source, comes primarily from carbohydrates in food and drinks. Your blood carries glucose to all cells for energy, with various processes regulating blood glucose levels. Insulin, a hormone produced by the pancreas, plays a key role in maintaining these levels. High blood glucose (hyperglycemia) often indicates diabetes, a condition where the pancreas produces insufficient insulin, or the body doesn’t respond to it effectively.

What is a blood glucose (sugar) test?

A blood glucose test measures the level of glucose (sugar) in your blood, primarily to screen for diabetes. There are two main types:

• Capillary Blood Glucose Test: A drop of blood, usually from a fingertip prick, is tested using a glucose meter (glucometer) for quick results.
• Venous (Plasma) Blood Glucose Test: A sample is taken from a vein and analyzed in a lab, typically as part of a larger blood panel. This method is more accurate than the capillary test.

Fasting blood glucose tests are often used to provide a clearer picture of your baseline sugar levels. For individuals with diabetes, especially Type 1, regular monitoring through at-home testing or continuous glucose monitoring (CGM) devices is essential for managing blood sugar levels effectively.

When would I need a blood glucose test?

There are three primary reasons for needing a blood glucose test:

• Your healthcare provider may include it as part of routine bloodwork, such as a basic metabolic panel (BMP) or a comprehensive metabolic panel (CMP).
• You may be experiencing symptoms of high or low blood sugar, possibly indicating diabetes or another condition.
• If you take long-term medications that affect blood sugar, such as corticosteroids, regular glucose tests may be required to monitor your levels.

Blood glucose tests are commonly used to screen for Type 2 diabetes (T2D), a prevalent condition, especially for those with risk factors. The American Diabetes Association recommends regular screening for individuals 35 and older. Providers may also order a test if you exhibit symptoms of high blood sugar (hyperglycemia) or low blood sugar (hypoglycemia).

Symptoms of high blood sugar include:

• Excessive thirst (polydipsia)
• Frequent urination (polyuria)
• Fatigue
• Intense hunger (polyphagia)
• Unexplained weight loss
• Blurred vision
• Slow healing of cuts or sores. 

What is the normal glucose level in a blood test?

A normal fasting blood glucose level for someone without diabetes typically ranges from 70 to 99 mg/dL (3.9 to 5.5 mmol/L). In some cases, values between 50 and 70 mg/dL (2.8 to 3.9 mmol/L) may also be considered normal for individuals without diabetes.

What does a high blood glucose level mean?

If your fasting blood glucose level is between 100 and 125 mg/dL (5.6 to 6.9 mmol/L), it indicates prediabetes. Individuals with prediabetes have a 50% chance of developing Type 2 diabetes within 5 to 10 years, but preventive measures can be taken to reduce this risk. A fasting blood glucose level of 126 mg/dL (7.0 mmol/L) or higher on more than one occasion is typically associated with diabetes.

In either instinct, your healthcare provider may request an A1c test, which measures your blood sugar levels over the past few months, to confirm a diagnosis of prediabetes or diabetes.

The most common types of diabetes include:

• Type 2 diabetes (T2D): Occurs when the pancreas does not produce enough insulin or the body becomes resistant to insulin, causing high blood sugar levels.
• Type 1 diabetes (T1D): An autoimmune condition where the immune system attacks insulin-producing cells in the pancreas, leading to very high blood glucose levels.
• Gestational diabetes: A form of diabetes that develops during pregnancy, typically between 24 and 28 weeks, and usually resolves after childbirth.

Other causes of high glucose levels

• Adrenal gland disorders, such as Cushing syndrome.
• Pancreatic conditions, like pancreatitis.
• Hyperthyroidism.
• High levels of stress, such as from surgery or trauma.
• Certain medications, particularly corticosteroids.

What does a low blood glucose level mean?

A blood sugar level of 70 mg/dL or lower is generally considered low. Hypoglycemia, or low blood sugar, is common in individuals with Type 1 diabetes and in those with Type 2 diabetes who take specific medications. However, it is much rarer in people without diabetes.

For those without diabetes, low blood glucose levels may indicate conditions such as:

• Liver disease
• Kidney disease
• Hypothyroidism
• Addison’s disease (adrenal insufficiency)
• Alcohol use disorder (AUD)
• Insulinoma (a rare tumor)

These conditions typically cause recurring episodes of low blood sugar. A single low blood sugar reading in someone without diabetes is usually not a cause for concern.

Nearly 30 million people in the U.S. have some form of diabetes, yet 1 in 4 are unaware they have the disease. Each November, National Diabetes Month serves as a reminder to increase awareness about the risk factors, symptoms, and different types of diabetes.

Life with Diabetes

This year, 1.4 million people will be diagnosed with diabetes. If you’ve recently been diagnosed, you may feel overwhelmed and confused, but there are ways to manage your diabetes through diet, exercise, medical support, and emotional care. Take time to process your diagnosis, then take action by connecting with resources and support groups that can help you live a long, healthy life alongside others who understand what you’re going through.

Type 1 Diabetes

Type 1 diabetes is believed to result from an autoimmune reaction, where the body mistakenly attacks itself, stopping insulin production. About 5-10% of people with diabetes have type 1. Symptoms can develop rapidly, often in children, teens, and young adults. If diagnosed with type 1 diabetes, daily insulin is essential for survival, and currently, there is no known way to prevent it.

Living with Type 1 Diabetes

Managing type 1 diabetes involves regularly monitoring blood glucose and administering insulin through injections or a pump. If you’re newly diagnosed, remember you have many tools to help manage your condition. Learn how to regulate your blood glucose levels, insulin intake, diet, and exercise, and work closely with your diabetes care team to maintain your health.

People with type 1 diabetes can lead healthy lives. Seek out others with the condition to share experiences, tips, and advice. Whether you’re curious about using an insulin pump or need practical advice, connecting with others can make managing your diabetes easier. Don’t hesitate to ask for help or share your feelings with those around you.

Type 2 Diabetes

Type 2 diabetes occurs when the body doesn’t use insulin effectively, leading to elevated blood sugar levels. Around 90-95% of people with diabetes have type 2. It develops over several years and is usually diagnosed in adults. Because symptoms can be subtle, it’s important to have your blood sugar tested if you’re at risk. Type 2 diabetes can often be prevented or delayed with healthy lifestyle changes like:

• Losing weight
• Eating nutritious foods
• Staying physically active

Taking Medication

Medication is crucial for managing type 2 diabetes. Work with your care team to find the right medications to help you reach your target blood glucose range. Here are some questions to ask about your medication:

• How much do I take and how often?
• Should I take it with or without food?
• What side effects might occur, and what should I do if they happen?
• Will this medication interact with others I’m taking?

Eat Well and Get Moving

Whether you have type 1 or type 2 diabetes, diet and exercise are powerful tools for managing your condition. They not only help control blood glucose but also can significantly impact how you feel day-to-day.

Eat Healthy

Starting a new diet can feel restrictive, and there’s no one-size-fits-all approach. Be patient with yourself and seek guidance from your care team. Remember to:

• Eat a variety of foods, including vegetables, whole grains, fruits, low-fat dairy, healthy fats, and lean proteins.
• Space your meals evenly throughout the day.
• Avoid skipping meals.
• Steer clear of foods high in sugar with little nutritional value (“bad carbohydrates”).

Get Active

Physical activity, in any form, helps lower blood glucose. It also provides benefits like:

• Increased energy
• Reduced stress
• Improved joint flexibility
• Lowered risk of heart disease and stroke

Aerobic Exercise: Aim for at least 150 minutes per week of moderate to vigorous activity (like brisk walking, swimming, biking, or running), with a goal of 30 minutes or more most days.

Resistance Exercise: Engage in resistance training (such as weightlifting, yoga, or calisthenics) at least 2-3 times a week to enhance strength, balance, and overall activity levels.

Limit Inactivity: Reducing long periods of sitting can help control blood sugar. Take breaks to stand, walk, or do light activity every 30 minutes.
