為什么醫(yī)生建議人們吃紫色的蔬菜?

According to a study published in the Journal of Agricultural and Food Chemistry (a scientific journal founded in 1953 by the American Chemical Society.), Anthocyanins present in raspberries reduce the formation.

根據(jù)一項發(fā)表在《農(nóng)業(yè)與食品化學雜志》(美國化學學會于1953年創(chuàng)辦的科學雜志)上的研究，樹莓中的花青素可以減少這種物質的形成。

The researchers suggest that this anthocyanin blocks oxidation and enhances the activity of other important antioxidants, such as natural glutathione in the body.

研究人員認為，這種花青素可以阻止氧化，增強其他重要抗氧化劑的活性，比如人體內的天然谷胱甘肽。

2. Promote cardiovascular health

促進心血管健康

Some purple fruits like blackcurrants and bilberries have the ability to lower LDL (bad) cholesterol and raise HDL (good) cholesterol.

一些紫色的水果，如黑醋栗和越桔，能夠降低低密度脂蛋白(有害的)膽固醇，提高高密度脂蛋白(有益的)膽固醇。

Increased LDL cholesterol levels lead to the formation of plaque on the artery walls. And these plaids limit the natural flow of blood to the heart and the whole body, thereby putting you at risk for serious heart attacks and strokes.

低密度脂蛋白膽固醇水平的升高會導致動脈壁上斑塊的形成。這些格子圖案限制了流向心臟和全身的血液的自然流動，從而使你面臨嚴重心臟病和中風的風險。

3. Inhibiting cancer cells

抑制癌細胞

Many studies have shown that resveratrol in purple food can kill cancer cells that cause blood cancer, breast cancer, prostate cancer, skin cancer, liver and lung cancer. Purple sweet potatoes are extremely beneficial in fighting bowel cancer.

許多研究表明，紫色食物中的白藜蘆醇可以殺死引起血癌、乳腺癌、前列腺癌、皮膚癌、肝癌和肺癌的癌細胞。紫紅薯對對抗腸癌非常有益。

4. Enhance memory

增強記憶

Purple sweet potatoes are thought to enhance memory because they contain anthocyanins, which help prevent the decline of the longevity of the nervous system, promote learning and memory.

紫紅薯被認為能增強記憶力，因為它們含有花青素，有助于防止神經(jīng)系統(tǒng)壽命的下降，促進學習和記憶。

5. Prevent urinary tract infections

預防尿路感染

Vegetables such as purple carrots, cauliflower, and purple cabbage can prevent the risk of urinary tract infection thanks to Anthocyanin - the substance that prevents ulcers and inflammation caused by H. pylori, the bacteria that cause stomach ulcers and Urinary tract infection caused.

紫胡蘿卜、花椰菜和紫卷心菜等蔬菜含有花青素，可以預防尿道感染。這種物質可以防止幽門螺桿菌引起的潰瘍和炎癥，幽門螺桿菌是引起胃潰瘍和尿道感染的細菌。

6. Reduce blood pressure

降低血壓

Purple grapes, cranberries and blueberries contain resveratrol, a type of flavonoid that can help lower blood pressure. Resveratrol relaxes artery walls and helps better blood circulation in arteries.

紫葡萄、蔓越莓和藍莓含有白藜蘆醇，這是一種類黃酮，可以幫助降低血壓。白藜蘆醇可以放松動脈壁，促進動脈中的血液循環(huán)。
