Grapefruit vs Blueberry - Health impact and Nutrition Comparison
Blueberry and grapefruits are excellent additions to everyday diets. They both provide numerous health benefits, and they are packed with antioxidants. It is essential to check their drug-food interactions. Blueberry is richer in vitamin K and grapefruit is richer in vitamin A and C.
Table of contents
This article will compare blueberry and grapefruit, focusing on their nutritional content and health impacts.
We will be focusing on the difference each food provides based on nutrition and health impacts.
Nutritional content comparison
85% of blueberry is water, and 89% of grapefruit is water.
This means that most fruits are water, and macronutrients, vitamins, and minerals are all distributed in the remaining.
They are very low in calories. Blueberries are slightly higher in calories.
Blueberry is higher in carbs by 1.5 times.
The glycemic index of blueberries is double of grapefruits. However, they are both classified as low glycemic index fruits.
Blueberries are richer in fibers compared to grapefruit. Blueberry contains 2.4g of fiber, grapefruit contains 1.6g of fiber.
Proteins and fats
They both contain negligible amounts of both proteins and fats.
Blueberries are richer in vitamin K. The amount of vitamin K in blueberries is remarkable. 300g of blueberries satisfy 50% of the daily recommended value of vitamin K. In comparison, grapefruits are richer in vitamin C and A.
The diagrams below display their vitamin distributions.
The mineral profiles of both fruits are not very remarkable. However, blueberries contain higher amounts of copper than grapefruit.
Below we can see the mineral distribution diagrams.
In this section, we will focus on the health impact differences each food provides.
In the case of blueberry, it is richer in vitamin K and anthocyanins, which are the main different health impact providers.
Anthocyanins in blueberries have antioxidative properties, and it decreases oxidative stress, reducing risks of cellular damage, reducing risks of cancers, and risks of neurodegenerative diseases and cardiovascular diseases. (1)
In addition to anthocyanins, vitamin K provides health benefits. It reduces the risks of arterial calcification, which reduces mortality risks from cardiovascular diseases.
Vitamin K reduces risks of osteoporosis and has control over insulin level spikes, reducing risks of diabetes development. (2)(3)
On the other hand, we have grapefruits that provide positive health impacts, mainly through their richer content of vitamin C, furanocoumarins, and pectin.
Grapefruits reduce the risks of cardiovascular health diseases. Furanocoumarins have anticarcinogenic properties. In parallel with vitamin C, it provides antioxidative properties.
Pectins in grapefruits provide antidiabetic properties and reduce hyperglycemia. In addition, pectins reduce blood lipid levels reducing the risks of atherosclerosis. (5)(6)(7)(8)
Spikes or fluctuations in vitamin K levels while taking anticoagulant drugs such as warfarin can interact. Thus, it is important to keep the vitamin K levels stable and not increase them suddenly by consuming high amounts of blueberries if taking anticoagulation medications. (4)
Grapefruits should not be taken with certain medications such as lipid-lowering and hypertension. They affect the elimination and absorption of the drug, increasing their side effects. (9)
