An increasing body of evidence suggests that blueberries and anthocyanins reduce biomarkers and risk of diseases that constitute major socioeconomic burdens, including cardiovascular disease (CVD), type 2 diabetes mellitus (T2DM), and neurological decline. Recently, gut doctor Saurabh Sethi shared several benefits of blueberries and how consuming the fruit for 14-days will improve overall health.
Blueberries have emerged highly beneficial as they contain low calories and several essential nutrients. If you consume 100 grams of blueberries, you will get 57kcal. Regular intake of blueberries can support brain health, heart health, and blood sugar management. The superfood is loaded with nutrients that can improve memory, reduce DNA damage, lower blood pressure, and bring down muscle damage after strenuous exercise.
The presence of high fibre content in blueberries can slow down digestion, improve insulin sensitivity, and bring down the risk of developing type 2 diabetes.
According to a study featured in National Library of Medicine, “An increasing body of evidence suggests that blueberries and anthocyanins reduce biomarkers and risk of diseases that constitute major socioeconomic burdens, including cardiovascular disease (CVD), type 2 diabetes mellitus (T2DM), and neurological decline.” 1
Recently, Dr. Saurabh Sethi, AIIMS-trained gastroenterologist and liver specialist, also educated at Harvard and Stanford, took to his Instagram account and shared the benefits of eating blueberries for 14 consecutive days. Sharing the post, the gut doctor said, “If you ate blueberries everyday for 14 days, this is what could happen.” 2
1. Your Brain Will Benefit: Dr Saurabh Sethi said, “Blueberries are rich in anthocyanins, which are plant compounds linked to memory and cognitive function.”
2. Your Gut Will Benefit: The AIIMS-trained doctor said, “blueberries contain fibre & polyphenols that help feed beneficial gut bacteria.”
3. Your Blood Sugar Response Will Improve: “Despite being sweet, blueberries have a low glycemic impact, and their polyphenols can help improve insulin sensitivity. And if fresh one are not available, frozen ones work just as fine. They retain most of the same nutrients. A small serving that is about half to one cup can be an excellent addition for most people. Just make sure to rinse properly with either baking soda or vinegar to reduce pesticides residues.”
If you eat 100 grams blueberries, you will get the following vitamins and minerals given below:
Improves Body Functions: Apart from being low in calories, the nutrient-rich blueberries can boost various body functions. The fruit is rich in vitamin C that can enhance your immune health and support other functions. It contains manganese that can support brain health, improve muscle, and bone health. It is rich in vitamin K that can help your body clot effectively.
Fights Oxidative Stress: The superfood has high content of antioxidant that can fight oxidative stress. It is worth mentioning that unstable oxygen molecules known as free radicals can lead to oxidative stress and harm cells. As blueberries contain antioxidants, it can fight these free radicals. Antioxidants can generate a barrier or shield around cells to protect them from being harmed. Blueberries are high in antioxidant namely anthocyanins that give them their deep blue colour.
Manages Cholesterol: They are rich in soluble fibre that can help manage cholesterol levels. Soluble fibre binds to the bile in the gut and helps eliminate it from the body. According to a report featured in Cleveland Clinic, bile is waste made of substances known as salts, metals, and cholesterol. 3
Eliminating that bile can lead to decline in total cholesterol that can bring down the overall risk of heart disease.
Manages Blood Sugar: The fruit has high amount of fibre and less sugar content when compared with other fruits. Blueberries’ glycemic index is also low at just 53 and that’s why they do not cause blood sugar spike. According to a latest study where men with Type 2 diabetes were given blueberries every day, it reduced some factors liked to heart health such as triglycerides.
Reduces Muscle Damage: Hard exercises can cause muscle tiredness and soreness due to local inflammation and oxidative stress in muscle tissue. Blueberries may lessen the damage that can take place at a molecular level subsequently leading to reduced soreness. Blueberries can improve exercise performance and reduce some inflammatory markers that can support recovery.
FAQs
What are the main benefits of eating blueberries every day for 14 days?
Eating blueberries daily for 14 days can improve brain health through anthocyanins, support gut health by feeding beneficial bacteria with fiber and polyphenols, enhance blood sugar response by improving insulin sensitivity, reduce muscle damage after exercise, and aid in managing cholesterol levels due to their soluble fiber content.
How many blueberries should I consume daily to gain health benefits?
A recommended serving is about half to one cup (approximately 50-100 grams) of blueberries per day. This portion is enough to provide key nutrients, improve insulin sensitivity, and contribute to heart and brain health. Both fresh and frozen blueberries retain most of the beneficial nutrients.
Can blueberries help manage blood sugar and diabetes risk?
Yes, blueberries have a low glycemic index (around 53) and are high in fiber and polyphenols, which improve insulin sensitivity and slow digestion. Studies show that daily blueberry consumption can lower factors linked to type 2 diabetes and cardiovascular health, making them beneficial for blood sugar management.
Are blueberries effective in reducing muscle soreness after exercise?
Blueberries contain antioxidants and anti-inflammatory compounds that reduce oxidative stress and local inflammation in muscles caused by strenuous exercise. Regular intake can decrease muscle damage at a molecular level, improving exercise recovery and reducing soreness.
Do blueberries support heart health, and how do they affect cholesterol?
Blueberries support heart health by managing cholesterol through their soluble fiber, which binds bile in the gut and aids its elimination. This process helps lower total cholesterol levels, reducing the risk of cardiovascular disease. Additionally, anthocyanins in blueberries contribute to overall heart health.
