Diet for Prediabetes
Prediabetes is a condition where a person's blood sugar levels are higher than normal, but not high enough to be diagnosed as type 2 diabetes. People with prediabetes usually have some insulin resistance, which means the body isn’t using insulin effectively. Prediabetes is considered a warning sign that a person is at risk for developing type 2 diabetes in the future.
Researchers believe excess weight is a major cause of insulin resistance. It appears that belly fat may make hormones or other substances that contribute to insulin resistance. Reducing belly fat and excess weight may help the body respond better to insulin. It potentially may reverse prediabetes or help slow the progression to type 2 diabetes. In a study from the National Institutes of Health, people at high risk of developing diabetes and who reduced their starting weight by 5% to 7% were able to reduce their chances of developing diabetes. People were able to lose weight by changing their diet and being more physically active. For someone weighing 200 pounds, a 5% to 7% weight loss is 10 to 14 pounds.
A recommended diet for people with prediabetes focuses on maintaining steady blood sugar levels (avoiding large spikes in blood sugar) and promoting overall health. It includes a balance of foods to supply needed nutrients with a focus on the amount and type of carbohydrates (sugar or energy foods) eaten. Refined and processed carbohydrates are digested quicker and lead to higher spikes in blood sugar. People with prediabetes and insulin resistance may not be able to lower their blood sugar as well as people without prediabetes. A healthy diet can help with weight management, improve heart health, and provide essential nutrients for overall well-being.
Here are food examples that are part of a recommended diet for prediabetes:
- Carbohydrates: Fruits, vegetables, whole grains, legumes
- Protein: Lean meats (chicken, turkey), fish, shellfish, eggs
- Healthy fats: Olive oil, avocados, nuts
On the other hand, it is important to avoid certain foods that can negatively impact blood sugar levels:
- Processed foods: These often contain added fats, calories, and sugars without much nutritional value.
- Red meat: Consuming too much red meat can increase the risk of prediabetes.
- Trans fats: Products like processed snacks and stick margarines that contain trans fats should be avoided.
When incorporating the recommended diet into your daily habits to prevent diabetes, here are some helpful tips:
- Eat a "clean" diet: Avoid processed foods and opt for healthier choices that can help restore normal blood sugar levels.
- Focus on low-fat and low-calorie foods: Incorporate fruits with complex carbs, vegetables, lean meats, whole grains, and healthy fats like avocado and fish.
- Include high-fiber foods: Vegetables, whole grains, and legumes are high in fiber and can help moderate blood sugar levels.
- Be mindful of portion sizes: Pay attention to portion sizes to ensure you're not consuming excessive amounts of carbohydrates or calories.
- Consult your doctor or a registered dietitian: They can provide personalized guidance based on your specific needs and help you create a meal plan that works best for you.
Remember to always consult your doctor before making any significant changes to your diet or starting any new exercise routine. They can provide tailored advice based on your individual health needs.
