Many of the health benefits of pomegranates come from the fact that they are packed with vitamins, minerals, and nutrients. Pomegranates also contain important antioxidants that help you resist infection and keep your brain healthy. Also, the anti-inflammatory effects of pomegranate can help protect you against chronic disease.

In this article, you will learn about the many reasons why pomegranate juice and pomegranate seeds are good for you.

What Is Pomegranate?

The pomegranate (botanical name, Punica granatum) is a red-colored edible fruit that grows in the Middle East and in countries around the Mediterranean.

Pomegranate fruits grow on trees and have a thick skin and are full of edible seeds surrounded by arils. Pomegranate arils are tiny seed pods and there are about 600 of them in each pomegranate. (1)

The peel of pomegranates is too thick to be eaten. However, pomegranate peel extracts can be made into pomegranate powder and used for their antioxidant properties.

The seeds from the pomegranate fruit are encased in small red-colored sacs (pomegranate arils). Pomegranate seeds can be eaten raw or can be pressed to produce pomegranate seed oil. Researchers have discovered that edible pomegranate seeds contain antioxidants and have protective effect against free radicals. (2)

The journal Advanced Biomedical Research reports that pomegranates have been linked to lowering a person’s risk of coronary heart disease, high cholesterol, inflammatory diseases, and cancer. (1)

Many people say that pomegranates have a sweet taste with hints of sharp, tart taste. Researchers say that the unique taste of pomegranates comes from the many volatile compounds in the flesh and seeds. These can give pomegranates a taste that some describe as “earthy”, “sweet”, “floral”, or “fruity”. (3)

To get the benefits of pomegranates, you can eat the seeds straight from the fruit or drink pomegranate juice.

What Is Pomegranate Juice?

Pomegranate juice is a potent health drink that is extracted from the pomegranate arils.

Many researchers describe pomegranate juice as a “heart-healthy fruit juice.” Pomegranate juice is extremely good for you because it has a high antioxidant content. Consuming pomegranate juice can help lower blood pressure and has even been linked to fighting various bacterial infections. (4, 5)

Another reason why pomegranate juice is good for you is that it contains many vitamins and minerals that are essential to good health. Concentrated pomegranate juice may even have more minerals such as magnesium and potassium than regular pomegranate juice. (5)

It is very easy to juice a pomegranate to enjoy a delicious healthy drink. Cut one pomegranate in half and gently knock out the pomegranate arils or seeds. Put all the removed seeds into a blender and blend until the seeds are broken up. Strain the liquid into a cup to obtain the pomegranate juice. If the pomegranate juice is too tart for you, you can sweeten it by adding a teaspoon of raw honey.

Pomegranate Nutrition Facts

Pomegranate seeds and juice are packed with nutrients that have many health benefits.

For example, the seeds and arils from one pomegranate contain 234 calories, 52 grams of carbohydrates and 38 grams of sugar. This 282-gram serving of pomegranate contains 11 grams of fiber which is 45% of your recommended daily intake (RDI). (6)

Regularly consuming pomegranates can bolster your immune system because one cup of pomegranate seeds contains 9 mg of vitamin C which is 15% of your RDI.

Pomegranate is also good for your blood and liver health because a whole pomegranate has 46 mcg of vitamin K which is 58% of your RDI.

Pomegranate juice and pomegranate seeds also contain good amounts of vitamin E and many of the B-group vitamins.

A glass of pomegranate juice (250g) also contains minerals such as calcium (3% RDI), potassium (15% RDI), manganese (12% RDI), and magnesium (4% RDI).

Pomegranate juice is a powerhouse of antioxidants

The high number of antioxidants is one of the reasons why pomegranate juice is good for your heart, brain, and immune system.

Pomegranates contain an impressive amount of vitamin C which is a natural antioxidant.

Scientific studies have shown that phenolic compounds in pomegranate juice such as tannins have a potent antioxidant effect. These tannins help to kill off free radicals that cause oxidative damage and can increase the risk of chronic diseases. (7)

Research has also shown that the antioxidant activity of pomegranate juice is 3 times greater than green tea or red wine. (7)

Researchers have found that compounds such as tannins and anthocyanins have a powerful effect in reducing your risk of cardiovascular disease.

For example, one of the heart benefits of pomegranate is its ability to reduce a buildup of artery plaque (atherosclerosis). In one clinical trial, patients consumed a glass of pomegranate juice daily. After 3 months, scientists observed that blood flow to the heart was increased when compared to the control (placebo) group. (9)

Pomegranate fruit juice can help lower blood pressure

One of the ways that consuming pomegranate juice improves your heart health is that it has an anti-hypertensive effect.

How to Eat Pomegranate

The best part of the pomegranate to eat are the delicious crimson arils or seeds contained in the fruit. The pomegranate arils are surrounded by a white pith which is bitter to taste.

Pomegranate skin is too thick to consume, but you can dry the peel and then grind it to make a powder.

To get the seeds out of a pomegranate, gently score the thick pomegranate skin around the middle of the fruit and split the fruit in half. Hold each half face down and gently tap on the skin with a wooden spoon to extract the delicious seeds.

Just be careful when getting the seeds out as the red juice of pomegranate arils can stain fabric.

You can eat pomegranate seeds fresh or you can store them in the freezer to consume at a later date.

You can also boost your health by making a refreshing cup of pomegranate tea. Seoklyu-cha, or pomegranate tea, is popular in Korea for its health benefits. All you have to do is fill a cup ¼ full with fresh or frozen lightly crushed pomegranate seeds. Fill the cup with hot water, steep for a few minutes, add some honey to taste once it has cooled somewhat, and enjoy your health-boosting pomegranate tea.

Don’t forget to eat the pomegranate seeds after you have finished your cup!

Side Effects

Pomegranates are a delicious, healthy fruit that can be safely eaten in normal doses.

Because pomegranate juice helps lower blood pressure, you should be careful when drinking pomegranate juice regularly. The juice may cause your blood pressure to become dangerously low if you already suffer from low blood pressure.

Some people could have an allergic reaction to consuming pomegranate juice or pomegranate seeds.

  1. surrinder Bambrah says:

    I am obliged to thank you for showing the benefit of pomegranate.But I would like to know how the pomegranate seed could be dried for daily use? Can it be dried under slow heat and kept in a glass jar?

    What about the skin of the pomegranate – can it be made as powder and used daily? Does 1 teaspoon of dried seed powder in the morning can clear the blocked arteries.

    I will appreciate your comments.
    Thanks

    • Jenny Hills, Nutritionist and Medical Writer says:

      I’ve never tried to dry the seeds as I usually consume them fresh together with the tasty arils. The medical studies about the benefits of pomegranate consumption for the arteries were about the juice (and not about the powder of the skin). Please see the section “Pomegranate Is Good for Your Heart Health”. You’ll notice that the studies were about pomegranate juice. I am sure that the peel has its own benefits but I don’t have a specific study about it in relation to the arteries.

  2. Ben says:

    What amount of the juice do you recommend each day?

    • Jenny Hills, Nutritionist and Medical Writer says:

      Hi Ben, various studies used different amounts of pomegranate juice. The range was between 4 to 8 oz a day (120 to 240 ml). This is something like half cup to one cup.
