Polyphenols are naturally occurring compounds, giving plants color and protecting them from disease and other environmental threats and helping them recover from injury. These phytochemicals are found in plant foods such as spices, fruits and vegetables, seeds as well as legumes.

Consuming polyphenols on a regular basis, we become healthier in a number of ways as they eliminate free radicals in our body and drastically improve our overall health. We may even see a boost in our energy.

 


Polyphenols (also known as polyhydroxyphenols) are a structural class of mainly natural, but also synthetic or semisynthetic, organic chemicals characterized by the presence of large multiples of phenol structural units. The number and characteristics of these phenol structures underlie the unique physical, chemical, and biological (metabolic, toxic, therapeutic, etc.) properties of particular members of the class. Examples include tannic acid (image at right) and ellagitannin (image below). The historically important chemical class of tannins is a subset of the polyphenols…..

多酚
多酚(英語:polyphenol),亦作聚酚,是指一組植物中化學物質的統稱,因具有多個酚基團而得名。多酚在一些植物中起到了呈現顏色的作用,如秋天的葉子。

多酚類物質具有很強的抗氧化作用,常見的多酚化合物有:兒茶素、綠原酸、異黃酮、花青素、可可多酚、薑黃素、檸檬黃素、槲皮素(quercetin)、芸香苷(rutin)、白藜蘆醇等。綠茶、葡萄及深色的蔬果都是多酚類物質的一個來源。

    • Anti-Inflammatory: Most polyphenols have anti-inflammatory properties.
    • Heart Health: Consuming these types of foods can have great benefits on the cardiovascular system, and can actually help to improve heart health.
    • Prevent Cancer: Many studies have shown that polyphenols contain anti-tumor and anti-carcinogenic properties.
    • Prevent Heart Disease: Studies have shown that polyphenols found in cocoa have been shown to reduce cardiovascular stress through by reducing LDL cholesterol, or “bad” cholesterol. Polyphenols also increase the dilation of blood vessels to promote circulation. Several studies show that the polyphenols in red wine can help keeping heart disease at bay.
    • Anti-Aging: Many experts trust that polyphenols, even applied topically, can reduce the effects of aging as they cut down on free radicals floating around in the body.
  • Protect Against Diabetes-Related Side Effects: Exposure to prolonged high blood sugars puts us at risk of developing some severe negative side effects such as retinopathy(視網膜病變) and neuropathy(神經病). Studies have demonstrated that polyphenols can help protect our body against some of these negative side effects.

 

Retinopathy is persistent or acute damage to the retina of the eye. Ongoing inflammation and vascular remodeling may occur over periods of time where the patient is not fully aware of the extent of the disease…
