What will affect blood sugar tests?
Blood glucose tests are an important method for diagnosing diabetes and monitoring blood sugar control. However, many people do not pay attention to their diet before checking, resulting in inaccurate results. This article will combine popular topics and hot topics across the network for the past 10 days to analyze which foods will affect blood sugar tests, and provide structured data for reference.
1. Dietary precautions before blood sugar test
Blood glucose tests usually include fasting blood sugar, postprandial blood sugar and glycated hemoglobin (HbA1c). Different checks have different dietary requirements:
| Check type | Dietary Requirements |
|---|---|
| Fasting blood sugar | Fasting 8-12 hours before the examination, only a small amount of water can be consumed |
| Postprandial blood sugar | Eat a normal diet before the examination, but avoid high-sugar foods |
| Glycated hemoglobin | No need to be on an empty stomach, but long-term diet can affect results |
2. Foods that affect blood sugar tests
The following foods may interfere with blood sugar levels before the examination, resulting in inaccurate results:
| Food Categories | Specific food | Causes of impact |
|---|---|---|
| High-sugar foods | Candy, cakes, sugary drinks | Directly increase blood sugar levels |
| High carbohydrates | Rice, bread, noodles | Convert to glucose after digestion |
| Alcohol | Beer, white wine, red wine | Influencing liver metabolism and interfering with blood sugar |
| caffeine | Coffee, strong tea, energy drinks | Stimulate adrenaline secretion and increase blood sugar |
3. Dietary advice before inspection
To ensure the accuracy of blood sugar tests, it is recommended to pay attention to the following before the examination:
1.Fasting blood sugar test: Fast after dinner the night before, drink a small amount of water to avoid eating or drinking sugary drinks after getting up in the morning.
2.Postprandial blood sugar test: Eat a normal diet before the examination, but avoid deliberately ingesting high-sugar foods to avoid artificially raising blood sugar.
3.Long-term dietary control: Glycoated hemoglobin reflects the average blood sugar level in the past 3 months, so a long-term high-sugar diet will directly affect the results.
4. Recent hot topics: Are sugar-free foods really “sugar-free”?
In the past 10 days, discussions about "sugar-free food" have become a hot topic. Many sugar-free foods, although not sucrose, may contain other forms of sugar or sweeteners that can still affect blood sugar. The following are the blood sugar effects of common sugar-free foods:
| Sugar-free food | Possible ingredients | Effects on blood sugar |
|---|---|---|
| Sugar-free biscuits | Maltitol, starch | May increase blood sugar |
| Sugar-free drinks | Aspartame, Aceme | Usually does not affect blood sugar |
| Sugar-free cake | Flour, fat | Carbohydrates still convert |
5. Summary
The accuracy of blood sugar tests is greatly affected by diet, especially high in sugar, high in carbohydrates and alcoholic foods. Before the examination, diet should be arranged reasonably according to the doctor's advice to avoid misdiagnosis or misdiagnosis caused by improper diet. For people with diabetes or at high risk, it is crucial to monitor blood sugar regularly and maintain healthy eating habits.
