衰老与癌症的克星-原花青素 / Aging and Cancer Killer - Proanthocyanidins



氧在维系生命中的地位十分重要,人缺少氧在几分钟之内就会死亡。氧通过血液循环运往全身,以满足细胞呼吸之用。但在此时有部分氧被酶所催化形成氧自由基,它们在人体内随处可见,到处游离,活跃且富于攻击性。自由基是含有一个不成对电子的原子团。电子必须成对出现才会稳定,因此自由基就需要到处夺取其他物质的一个电子,使自己变得稳定,这种现象就是氧化。被夺取了电子的物质遭到了破坏,导致人体正常细胞核组织的损坏,很多疾病就好接踵而来。


正常人体有一套清除自由基的系统,但这个系统的力量会因人的年龄增长及体质的改变而减弱,致使自由基的负面效应大大增强。同时外界的紫外线,各种辐射,吸烟,喝酒,工作压力,生活不规律等,更会使体内的自由基大量的产生。过量的自由基对人体的危害就像氧化作用腐蚀金属一样。它不仅加快人体衰老的过程,而且可能会引发正常细胞的DNA中的致癌基因,导致癌症。

幸运的是人类从大自然中发现很多天然的抗氧化物质,可以对抗过量的自由基。他们进入人体后,可以中和自由基多余的电子,从而清除自由基,使人体细胞免受伤害。目前发现维生素C,维生素E,辅酶Q10,硒,生物类黄酮都是有效的抗氧化物质。而在众多的抗氧化物质中,原花青素是迄今为止发现的最强有效的自由基清除剂之一。它是生物类黄酮的一种,它抗氧化程度是维生素C的20倍,维生素E的50倍,通常富含在葡萄籽中。

 有了原花青素的超强抗氧化能力,人类可以延缓衰老,增加人的健康年限。原花青素虽然本身并不能直接杀死癌细胞,但通过清除过量的自由基,可以抑制癌细胞的生长以及促进癌细胞的凋亡,从而发挥对抗癌症的作用。目前已经证实,原花青素有抗乳腺癌,前列腺癌,皮肤癌等作用。各种研究证明,原花青素在对抗过敏,心血管疾病、辐射等方面也有很好的作用。而配合了矿物质维生素C的原花青素,在人体内各种作用的时间会更持久。神奇的原花青素,已经被越来越多的科学家关注,并应用于保健品中,成为人类对抗衰老和癌症的克星。

Aging and Cancer Killer - Proanthocyanidins

Oxygen status is very important to maintain life, people lack of oxygen will die within minutes. Oxygen delivered to the body through the blood circulation to meet the cellular respiration purposes. But at this point, some oxygen is catalyzed by the enzyme to form oxygen free radicals, which can be seen everywhere in the body, around the free, active and full of aggression. A free radical is an unpaired electron containing atomic group. Must be stable electron pairs, so you need everywhere to capture a radical electron other substances to make themselves become stable, this phenomenon is oxidized. Was captured electronic material was destroyed, causing damage to the body's normal cells and tissues of many diseases like follow.
 

Normal body set free radical scavenging system, but the power of this system due to age and change people's constitution weakened, resulting in greatly enhanced the negative effects of free radicals. Meanwhile outside of ultraviolet rays, various radiation, smoking, drinking, work pressure, irregular life, etc., and even make a lot of free radicals generated. An excess of free radicals on the human body as oxidation corrosion of metal the same. It is not only accelerate human aging process, and may lead to DNA in normal cells oncogene, leading to cancer.

 Fortunately, humans find a lot of natural antioxidants from nature, can fight an excess of free radicals. After they enter the body, can neutralize free radicals excess electrons, which scavenge free radicals, the body cells from damage. Currently found that vitamin C, vitamin E, coenzyme Q10, selenium, bioflavonoids are effective antioxidants. In many antioxidants, the proanthocyanidins are one of the strongest effective free radical scavenger found so far. It is a bioflavonoid, which is 20 times the antioxidant level of vitamin C, vitamin E, 50 times, usually rich in grape seeds.

With powerful proanthocyanidins antioxidant capacity, humans can delay aging and increase human health life. Although proanthocyanidins itself does not kill cancer cells directly, but by removing the excess free radicals that can inhibit cancer cell growth and induce apoptosis of cancer cells, and thus play a role in the fight against cancer. It has been confirmed, proanthocyanidins have anti-breast cancer, prostate cancer, skin cancer, and so on. Various studies demonstrated that proanthocyanidins in the fight against allergies, cardiovascular diseases, radiation, etc. also have a good effect. And with the mineral vitamin C proanthocyanidins, a variety of roles in the human body time will be more durable. Magical proanthocyanidins, has been concerned about the growing number of scientists and applied health care products, anti-aging and cancer become a human killer.
