Blood tests are vital diagnostic tools that provide insights into our overall health. From cholesterol levels to nutrient deficiencies, these tests offer valuable information about our health to healthcare professionals.

However, did you know that your diet plays a crucial role in determining the results of these tests? What you eat can significantly impact various markers in your blood. In this blog, we’ll discuss how you can optimise your diet to achieve accurate blood test results.

What Foods Should You Avoid Before a Blood Test?

Before a blood test, there are certain foods you shouldn’t eat. This helps to make sure the test results are accurate by avoiding any interference. Following the food rules given by doctors is important for getting correct health information and managing medical care well.

1. Fatty Foods- Avoid high-fat foods like fried foods, creamy sauces, and fatty meats as they can affect lipid profiles.
2. Alcohol- Alcohol consumption can alter liver function tests and affect blood sugar levels. Avoid alcohol for at least 24 hours before a blood test.
3. Caffeine- Limit caffeine intake before a blood test, as it can temporarily elevate blood pressure and heart rate.
4. Excessive Sugar- Avoid sugary foods and beverages to prevent spikes in blood sugar levels.

Why is Fasting Necessary for Certain Blood Tests?

Fasting is necessary for certain blood tests, such as those measuring cholesterol and fasting blood sugar, to obtain accurate results. This helps to measure your levels properly without recent food affecting the results. It makes sure doctors can diagnose and treat you accurately.

For cholesterol tests, fasting for 8-12 hours helps measure levels of LDL, HDL, and triglycerides correctly. Similarly, fasting for 8-10 hours before a fasting blood sugar test ensures precise assessment of fasting blood glucose levels. This helps to aid diagnosing conditions like diabetes.

How to Quickly Improve Blood Test Results with Diet?

If you want to improve your blood test results with diet, focus on nutrient-dense foods, balanced macronutrient intake, and hydration. Implement portion control, limit processed foods, and prioritise whole grains, lean proteins, fruits, and vegetables.

Here are 5 ways to improve blood test results with diet-

1. Reduce Saturated Fat Intake- High levels of saturated fats can raise LDL cholesterol, often referred to as “bad” cholesterol. To improve cholesterol levels, opt for lean protein sources such as poultry, fish, legumes, and tofu instead of fatty meats. Incorporate healthy fats like avocados, nuts, and olive oil into your diet.
2. Increase Fibre Consumption- Fibre-rich foods like fruits, vegetables, whole grains, and legumes help lower cholesterol levels and regulate blood sugar. Aim for at least five servings of fruits and vegetables daily and choose whole grains over refined ones.
3. Limit Sugary and Processed Foods- Excessive sugar intake can lead to insulin resistance and elevated triglyceride levels. Minimise consumption of sugary beverages, desserts, and processed snacks. Opt for natural sweeteners like honey or maple syrup sparingly.
4. Include Omega-3 Fatty Acids- Omega-3 fatty acids found in fatty fish like salmon, mackerel, and sardines can help lower triglyceride levels and reduce inflammation. Consider incorporating fish into your diet at least twice a week. Plant-based sources of omega-3s include flaxseeds, chia seeds, and walnuts.
5. Stay Hydrated- Drinking an adequate amount of water is essential for optimal blood volume and circulation. Aim for at least eight glasses of water per day and limit consumption of sugary or caffeinated beverages.

What Foods Should You Eat to Improve Blood Test Scores?

If you are looking for the best diet for high cholesterol blood tests, incorporating a range of wholesome options such as fruits, vegetables, lean proteins, and whole grains can boost vital nutrients.

Foods that can improve your blood test scores are-

1. Leafy Greens- Kale, spinach, and Swiss chard are rich in iron and vitamins that can improve blood cell counts.
2. Lean Protein- Incorporate lean protein sources like chicken, turkey, tofu, and legumes to support muscle repair and overall health.
3. Whole Grains- Brown rice, quinoa, and whole wheat pasta provide essential nutrients and can help regulate blood sugar levels.
4. Berries- Blueberries, strawberries, and raspberries are packed with antioxidants that promote heart health and improve blood circulation.
5. Oats- Oats contain beta-glucan, a type of soluble fibre that helps lower LDL cholesterol.
6. Fatty Fish- Rich in omega-3 fatty acids, fatty fish like salmon, trout, and mackerel can improve cholesterol levels.
7. Nuts- Almonds, walnuts, and pistachios are high in monounsaturated fats and can help lower LDL cholesterol.
8. Olive Oil- Swap saturated fats with olive oil in cooking to reduce LDL cholesterol levels.
9. Fruits and Vegetables- Colourful fruits and vegetables are packed with antioxidants and fibre that promote heart health and lower cholesterol.
