Representative antioxidant foods Blueberry and frozen blueberry are effective and nutritious

There are 4 packs of 500g of blueberries in one box. I put the blueberries in the freezer right after leaving only one pack. When eating sun food in the morning, Sansam drinks bananas, blueberries, mulberries, and aronia alternately.

Blueberry, mulberry, raspberry-loving wild ginseng is too short to be self-sufficient in raising a blueberry in the countryside on a trial basis, so they will plant blueberries and aronia for about five weeks each in the fall.

representative antioxidant foods that prevent aging

Blueberries, which help prevent aging by removing active oxygen from our bodies, are representative antioxidants with the highest anthocyanin content among fruits.

The strong effect of blueberries comes from anthocyanin, a purple ingredient, and research shows that blueberries and 40 different fruits and vegetables have the greatest antioxidant effect.

Blueberry is said to produce 15 types of anthocyanin by combining five types of anthocyanidine, Delphinidine, cyanidine, petunidine, malvidine, and peonidine with three types of sugars: glucose, galactose, and arabinos.


The current national blueberry is by the National Standard Plant List Committee (2011). Blueberry is derived from the English name Blueberry, which means that the fruit is dark blue and resembles a strawberry.

학명 Vaccinium corymbosum L.

The generic name Vacinium is presumed to be derived from the Latin word vacinus (cow) influenced by the German slang term Kuhteke, and in another view, the name has nothing to do with vacca (cow) and Hyacinthus was changed to the Greek name Vacinthos. The species name corymbosum means ‘with mountain fire’.

Originating from Blueberry origin

Blueberries, which were selected as one of the world’s top 10 health foods by the New York Times in 2002, are one of North America’s native fruits that have been harvested wild for thousands of years and each part has been used for medicinal purposes.

Blueberries began crossbreeding in New Hampshire and New Jersey in 1908, and began to be produced in many countries around the world in the early 1990s, accounting for 90% of the world’s blueberries in North America, such as the United States and Canada.

Blueberries began to emerge as a “21st century well-being fruit” and were rich in antioxidants, so the U.S. Department of Agriculture (USDA) selected them as the best anti-aging food along with soybeans.

Blueberry effect

Blueberries are considered a powerful antioxidant due to their highest anthocyanin content among fruits. Antioxidants are the root of all diseases and remove excess free radicals, the main culprit of aging.

Blueberries are rich in anthocyanins, as well as in phenolic compounds such as carotenoids, flavonoids, chlorogenic acids, and proantocyanidine, which inhibit active oxygen, prevent aging, and are good for blood circulation.

According to a study by the National Institute of Horticultural Science under the Agricultural Promotion Agency, blueberries can reduce bad cholesterol levels in our bodies, which reduces the likelihood of stroke and cardiovascular disease caused by cholesterol accumulation.

The anthocyanin component of blueberry promotes the activation of rhodopsin resynthesis in the eye retina, which also has the effect of improving vision and suppressing vision loss. When the “overwork” of the eyes persists or gets older, rhodopsin slowly decomposes and vision decreases, because blueberry’s anthocyanin functions to promote re-synthesis of rhodopsin.

According to research data from the National Cancer Information Center, blueberry anthocyanin has a function to detoxify carcinogens in the body, helping prevent cancer, and blueberry’s rich dietary fiber is effective in preventing constipation and colon cancer.

100g of blueberries contains about 3g of dietary fiber, 2.5 times as much as bananas. The fiber contained in blueberries suppresses the absorption of sugar and cholesterol in the intestine and prevents the production of harmful substances, making the intestines healthy. It is good for constipation and prevents colon cancer because of this function.

Blueberries are also called natural Viagra because they lower cholesterol levels and help blood circulation, which supplies a lot of blood to men’s genitals so that they can have good erection.

Blueberries, also called purple gifts from God, contain polyphenol, an antioxidant that turns active oxygen, a harmful oxygen in the body, into harmless substances, which is also effective in improving memory and concentration, which is good for brain health such as preventing dementia.

Blueberry Efficacy Summary

Rural Development Administration

Strong antioxidant and anti-aging effects

Anthocyanin, a purple component of blueberries, is good for preventing dementia by neutralizing active oxygen that causes chronic diseases, cancer, and aging and suppressing the occurrence of inflammation that causes brain nerve damage.

A study by the U.S. Department of Agriculture comparing blueberries with more than 40 other fresh fruits and vegetables showed that blueberries had the greatest antioxidant effect.

a reduction in cholesterol levels

Blueberries reduce bad cholesterol levels in the body, reducing the incidence of stroke and cardiovascular disease caused by cholesterol accumulation, and are also effective in obesity.

Eye protection and improvement

Blueberry’s anthocyanins relieve eye fatigue, improve vision loss, and help improve cataracts and dry eyes.

Constipation and colon cancer prevention effects

Dietary fiber rich in blueberries helps intestinal health by suppressing the absorption of sugar and cholesterol in the intestine and preventing the production of harmful substances.

Improves skin wrinkles

Blueberry’s anthocyanins, polyphenols, and beta-carotene are also effective in improving back wrinkles.

Prevention and Improvement of Diabetes

Anthocyanin reduces blood sugar levels that cause diabetes, and it is effective in improving diabetes symptoms by preventing blood sugar rise by releasing hormones.

Frozen blueberries are effective

Anthocyanin is the most effective antioxidant substance that prevents damage and aging of our bodies and prevents various diseases. To effectively consume blueberry anthocyanins, it is best to eat whole, including skin and seeds.

And blueberries are said to have a better health effect when frozen. This is because the antioxidant component is higher when stored in the freezer.

Blueberries are known to contain about 30 times more anthocyanins than grapes, and research shows that freezing of these anthocyanins, which are rich in blueberries, increases the concentration.
