Lycopene & Resveratrol

Resveratrol Prevents Against Cardiovascular Disease


Chinese, the first in the world, has been utilizing food therapy for more than 2000 years. Western countries, however, realized this only some 50 years ago.

In China, many resveratrol-containing plants, like Giant Knotweed Rhizome and Maltiflower Knotweed, have traditionally used for hypolipidemic, anti-atherosclerosis herbal medicines. Grapes contain abundant amounts of resveratrol. As a result, the incidence rate of high blood fat in French people, who love drinking red wine, is relatively low. Research found that in French red wine, resveratrol content is about 1 mg/L, with 7 mg/L being highest. In comparison, its content in the white wine is lower than 0.1 mg/L. The resveratrol content is dependent on grapes, condition of the producing region, pest invasion, and brewing technology. In fact, resveratrol was re-discovered as an active ingredient in Giant Knotweed Rhizome for reducing blood pressure by Arichi and co-workers. Therefore resveratrol’s hypolipidemic effect is undisputable.


The preventive effect of resveratrol on cardiovascular diseases is not only on blood fat reduction. Another important factor is because resveratrol is also a potent antioxidant. Resveratrol structurally belongs to polyphenols. These compounds have strong bio-antioxidant abilities. Although not as strong as lycopene, resveratrol after dietary intake has different distribution in the body, and therefore different effect. In the previous chapter about lycopene, the effects of bio-antioxidants have been mentioned, including anti-tumor, atherosclerosis prevention, and anti-ageing. The reason for the preventive function of bio-antioxidants on atherosclerosis has been clinically shown using resveratrol which reduces the oxidation of low density lipoprotein (LDL) which could lead to atherosclerosis.

Resveratrol was also shown to promote NO release and enhance anti-clotting function, which is the most important factor for reducing myocardial infarction.
Japanese research even proved that resveratrol has the protective effect on liver.
