Pre-meal elevated glucose levels issue?

I would like to ask the doctor, during a recent blood test, my fasting glucose level was 96.
Although it is still within the normal range of 70-100, should I make adjustments to my diet based on this value, or do glucose levels vary with each measurement, and as long as they are within the normal range, it is acceptable?

When it comes to slightly elevated fasting glucose levels, such as a reading of 96 mg/dL, which is still within the normal range of 70-100 mg/dL, it's essential to approach dietary adjustments with a balanced perspective. While your glucose level is not classified as prediabetes or diabetes, it does indicate that you should be mindful of your dietary choices to maintain optimal health and prevent potential future issues.

Firstly, it's important to understand that blood glucose levels can fluctuate due to various factors, including diet, physical activity, stress, and even the time of day. Therefore, a single reading should not be the sole basis for making significant dietary changes. However, consistently monitoring your glucose levels and understanding how your body responds to different foods can provide valuable insights.

Here are some recommendations to consider:
1. Balanced Diet: Focus on a well-rounded diet that includes a variety of foods. Incorporate whole grains, lean proteins, healthy fats, and plenty of fruits and vegetables. This approach not only helps maintain stable blood sugar levels but also provides essential nutrients for overall health.

2. Low Glycemic Index (GI) Foods: Opt for low-GI foods, which are digested and absorbed more slowly, leading to a gradual rise in blood sugar levels. Foods such as whole grains, legumes, nuts, seeds, and most fruits and vegetables can be beneficial. These foods can help stabilize your blood sugar and reduce the risk of spikes.

3. Limit Added Sugars and Refined Carbohydrates: While your current glucose level is normal, it's wise to limit foods high in added sugars and refined carbohydrates, such as sugary snacks, sodas, and white bread. These foods can cause rapid increases in blood sugar levels and may contribute to insulin resistance over time.

4. Regular Physical Activity: Engaging in regular exercise can significantly improve insulin sensitivity and help regulate blood sugar levels. Aim for at least 150 minutes of moderate-intensity aerobic activity each week, along with strength training exercises on two or more days.

5. Monitor Portion Sizes: Be mindful of portion sizes, especially when consuming carbohydrates. Eating large portions can lead to higher blood sugar levels, even if the foods are healthy.

6. Stay Hydrated: Drinking plenty of water is essential for overall health and can help maintain proper hydration, which is important for metabolic processes, including glucose regulation.

7. Regular Monitoring: Continue to monitor your fasting glucose levels regularly. If you notice a trend of increasing levels or if you experience symptoms such as increased thirst, frequent urination, or fatigue, consult with a healthcare professional for further evaluation.

8. Consult a Professional: If you have concerns about your glucose levels or dietary choices, consider consulting a registered dietitian or a healthcare provider. They can provide personalized recommendations based on your health status, lifestyle, and dietary preferences.

In summary, while a fasting glucose level of 96 mg/dL is within the normal range, it is a good opportunity to reflect on your dietary habits and make adjustments that promote long-term health. By focusing on a balanced diet, incorporating low-GI foods, and maintaining an active lifestyle, you can help ensure that your blood sugar levels remain stable and reduce the risk of developing insulin resistance or diabetes in the future.
