Pomegranate and grapefruit are both tangy and bursting with health benefits, but when it comes to antioxidants, which fruit delivers more?
Pomegranate and grapefruit are often referred to as “superfruits,” and for good reason. These fruits are packed with vitamins, minerals, and powerful antioxidants that help protect your body from oxidative stress and inflammation, but one offers a bit more antioxidant power.
Here’s how pomegranate and grapefruit stack up when it comes to antioxidants and overall health benefits.
Antioxidants are compounds that help protect your cells from damage caused by free radicals, which are unstable molecules produced in response to normal bodily functions and external factors like sun exposure, pollution, stress, and alcohol.
Too much free radical activity can lead to oxidative stress, which is a term used to describe an imbalance between antioxidants and free radicals and other harmful compounds. Oxidative stress is linked to health issues and increased risk of conditions such as heart disease, cancer, and neurodegenerative disorders.
Your body has its own antioxidant defense systems of enzymes and compounds to help maintain a balance between free radicals and antioxidants, but dietary antioxidants are also found in foods like fruits, vegetables, and spices, and supplements. Nutrients and plant compounds like vitamins C and E, selenium, zinc, carotenoids, flavonoids, and omega-3 fats are just some examples of antioxidants found in food.
Pomegranate and grapefruit both deliver antioxidants, but they offer distinct compounds with unique benefits.
Pomegranates are amongst the most antioxidant-rich foods you can eat. Pomegranate seeds, also known as arils, arils, are packed with polyphenols and flavonoids, including anthocyanins, ellagitannins and organic acids that have powerful antioxidant and anti-inflammatory activity.
Studies show that drinking pomegranate juice could help reduce markers of oxidative stress, such as malondialdehyde (MDA) and increase the total antioxidant capacity (TAC) of the blood.
Pomegranates are also high in vitamin C, which functions as a potent antioxidant in the body. A one-cup serving of pomegranate arils covers 19.7% of the Daily Value (DV). Vitamin C is needed for immune function, blood vessel health, and collagen production.
The same serving also covers nearly 25% of your daily fiber needs. Fiber is essential for supporting overall gut health, including the growth of beneficial bacteria and preventing constipation.
Grapefruit is a standout citrus fruit when it comes to antioxidants. Just one cup provides nearly 100% of your daily vitamin C needs, making it one of the best sources of vitamin C you can eat.
It’s also rich in flavonoid antioxidants like naringin and naringenin, as well as carotenoids, which work together to combat oxidative stress and inflammation in the body.
Studies show that drinking grapefruit juice can increase blood levels of vitamin C and naringin, as well as the radical scavenging ability (RSA) of the blood. RSA is a measure of the blood’s capacity to neutralize free radicals.
Research suggests that regularly eating citrus fruit may help reduce your risk of health conditions like gastric cancer and heart disease.
When it comes to antioxidant capacity, both of these fruits are excellent choices. Grapefruits have been shown to have a higher ORAC score, short for Oxygen Radical Absorbance Capacity. ORAC is a test that measures a food’s antioxidant capacity.
According to a 2021 study, grapefruit has an ORAC of 13,805, and pomegranate has an ORAC of 9,046. This suggests that grapefruit has a greater free radical-neutralizing power.
That said, pomegranate is a better source of polyphenols, which are powerful antioxidant compounds.
Unfortunately, no studies have directly compared the total antioxidant content of grapefruit and pomegranate.
Since both are rich in nutrients and antioxidants and offer unique health benefits, the best approach is to enjoy both as part of a well-rounded diet to promote overall wellness.
Both pomegranate and grapefruit are nutritious fruits that deliver antioxidants and other essential nutrients.
But when it comes to sheer antioxidant capacity, studies show that grapefruit has higher free radical-neutralizing power. However, pomegranate also provides powerful antioxidant protection.
It’s best to include a variety of antioxidant-rich foods, like grapefruit and pomegranate, in your diet to support overall health.
