The mature pomegranate is bright red in appearance. It is often used as a festive fruit because of its bright color and plump seeds. Now is the season for eating pomegranates. One large pomegranate a day is both thirst-quenching and delicious. Some people say that pomegranates are known as the "Chinese divine fruit" and are very nutritious; others say that pomegranates can beautify and fight cancer.

Pomegranate Nutrition and Health Benefits

Pomegranate is native to Iran, Afghanistan and other countries along the Mediterranean coast. It was introduced to China via the Silk Road during the Han Dynasty and has a cultivation history of more than 2,000 years.

Pomegranate is known as the "Magic Fruit of China", which makes people mistakenly believe that it is rich in nutritional value. In fact, most of the nutrients in pomegranate are at average levels. Apart from its good hydrating effect, only two nutrients are more prominent.

Dietary fiber: The insoluble dietary fiber content of pomegranate is 4.9g/100g, [1] which is considered high among fruits and nearly three times that of apples. It can promote gastrointestinal mechanical movement, aid defecation, prevent constipation, and promote intestinal health.

Mineral potassium: The potassium content of pomegranate is 231 mg/100 g, [1] which is comparable to the potassium content of bananas, which are known as potassium-rich fruits. Adequate potassium intake helps stabilize blood pressure, which is quite friendly for people who need to control blood pressure.

In addition to the above two nutrients, pomegranates can also provide us with some antioxidant ingredients, including gallic acid, chlorogenic acid, caffeic acid, protocatechuic acid, catechins and coumaric acid. [2] Taking more phenolic substances can help us resist oxidation and inflammation, but don’t expect eating them to beautify you or prevent cancer.

As for the vitamin C in pomegranate, the content is not very high. The data in the "Chinese Food Composition Table" shows that the vitamin C content in pomegranate is only 8mg/100g, which is the same as the vitamin C content in banana. Although it is nearly 3 times that of apple, it is far behind oranges and kiwis! It is only about 1/8 of that of kiwis.

However, there are documents showing that the vitamin C content of Kashgar pomegranate pulp can reach 681.9 mg/100 g, and the vitamin C content of Hotan pomegranate and Shaanxi pomegranate is also around 600 mg/100 g. [3] The vitamin C content of Heyin soft-seeded pomegranate is also relatively high, at 408.5 mg/100 g. [4] This may be due to differences between different varieties, and the data varies greatly, which needs further verification.

Soft-seeded pomegranate is good

Many pomegranates have seeds, and you have to spit out the seeds while eating, which is really troublesome! It doesn’t matter, you can choose a pomegranate with soft seeds.

Soft-seeded pomegranates are popular because of their soft and edible seeds. In particular, the Tunisian soft-seeded pomegranate is one of the most popular soft-seeded pomegranate varieties on the Chinese market. It was introduced to my country from Tunisia in 1986 and its price is 2 to 4 times that of ordinary pomegranate varieties.

There are many places in my country where Tunisian soft-seeded pomegranates are produced. Researchers compared Tunisian soft-seeded pomegranates from 13 places and found that the Tunisian soft-seeded pomegranates from Jianshui, Yunnan have the highest soluble sugar content, the highest sugar-acid ratio, the sweetest taste, and the largest fruit, with a single fruit weight of up to 880 grams; the soft-seeded pomegranates from Zhengzhou, Henan have the thinnest peel. [5]

Can I eat pomegranate if I have high blood sugar?

The sugar content of pomegranates is quite high, at 13.7%,[6] which is slightly higher than the total sugar content of bananas,[7] and some varieties of pomegranates have even higher sugar content.

The main sugar components of pomegranate fruit are sucrose, glucose, fructose and sorbitol. Glucose and fructose have the highest content, with fructose accounting for 9.18% to 50.67% of the total sugar, and glucose accounting for 43.84% to 48.36% of the total sugar. Sucrose and sorbitol are only small amounts. [8]

Although the metabolism of fructose has little effect on blood sugar, the metabolism of glucose has a relatively large impact on blood sugar. People with high blood sugar and diabetes should eat less. If you like, you can eat 100 grams each in the morning and afternoon as a snack, and pair it with a few nuts to help stabilize blood sugar.

It is important to note that you should not drink pomegranate juice in large quantities to avoid a spike in blood sugar. Data show that the glycemic load (GL) of pomegranate juice is 21,[9] and a GL>10 means that it has a greater impact on blood sugar.

Pomegranate is the most delicious fruit in autumn. A big spoonful of pomegranate is sweet and delicious, full of juice! Friends who like to eat pomegranates should make arrangements quickly, don't miss the opportunity!

in conclusion

Pomegranates are good at replenishing water, rich in dietary fiber and mineral potassium, but other nutrients are not prominent. In addition, pomegranates contain some phenolic substances. Taking more phenolic substances can help us resist oxidation and inflammation, but they have no beauty or anti-cancer effects.
