Drinking carrot juice could boost immune system and reduce inflammation, say researchers
Adding carrot juice to your daily nutrition routine could help promote better health.
A small study published in the journal Nutrients this month found that drinking carrot juice could help boost the immune system and reduce inflammation.
Researchers from the University of Southern Denmark took into consideration the bioactive compounds falcarinol (FaOH) and falcarindiol (FaDOH) found in carrot juice, which can affect inflammation.
Fourteen healthy volunteers between the ages of 20 and 55 had their blood tested before and then one hour after juice intake.
The volunteers consumed 30 grams of freeze-dried carrot powder mixed with 500 milliliters of tap water.
The study showed promising results following ingestion, which led researchers to believe that carrot juice intake could benefit people with certain diseases like diabetes and cancer, where inflammation comes into play.
"In contrast, carrot juice intake affected both pro- and anti-inflammatory cytokines in LPS-stimulated plasma samples one hour after juice intake compared to no juice intake," the study reported.
"Intake of carrots has acute effects on reactivity in parts of the innate immune system, and the bioactive compounds in carrots that can explain these effects are most likely acetylenic oxylipins such as FaOH and FaDOH."
Fox News Digital reached out to the study authors for comment.
Nutritionist and registered dietitian Ilana Muhlstein, who was not involved in the study, called the research "super interesting" in an interview with Fox News Digital.
"Carrots are the No. 1 food source of beta carotene, which is a precursor for vitamin A that’s vital for our immune system," said Muhlstein, who is based in Los Angeles.
Although these findings are helpful, Muhlstein suggested it would have been "even more beneficial" to carry out the same study with full carrots.
"People would have the added benefits of fiber, which gets removed when juicing fruits and vegetables," she said.
Muhlstein added that the fiber in carrots can function as a prebiotic, which can help aid in gut health and overall immunity.
"Fiber could also benefit blood sugar control, which may further help reduce inflammation in the body," she said.
"So, while I love this study, and it’s nice to see how people can benefit from carrot juice, I think it’s also important to remind people that they can achieve similar benefits, if not more benefits, by eating carrots as well."

中文简要说明：
拌色拉、打蔬果汁常见食材之一是胡萝卜，秋冬两季盛产期更是鲜脆多汁。丹麦最近发表一项研究指出，胡萝卜汁有助于增强免疫系统、减少发炎，对于糖尿病、癌症患者有益。胡萝卜营养丰富，对于人体至少有6大好处，适量摄取就能由里到外照顾你的健康。
美国福斯电视网（Fox News）报导，这项发表于《营养》（Nutrients）期刊的丹麦小型研究，观察胡萝卜汁里2种对于发炎有所影响的生物活性化合物镰叶芹醇（falcarinol，FaOH）、黄花苷二醇（falcarindiol、FaDOH）。
研究团队找了14名年龄介于20岁至55岁健康良好的志愿者，在胡萝卜汁饮用前与饮用后1小时接受血检，胡萝卜汁以30克冷冻干燥胡萝卜粉末加入500毫升的水混合而成。
结果显示，与没喝胡萝卜汁的人相较，受试者喝了胡萝卜汁1小时之后，体内诱发酯多糖（LPS）的血浆样本中，促发炎细胞激素与抗发炎细胞激素都受到影响。摄取胡萝卜会使先天免疫系统产生急性反应，胡萝卜之中能解释这种反应的化合物就是FaOH与FaDOH。接下来需要更多进一步研究证实胡萝卜汁对于促进免疫功能、减少发炎的详细影响程度。癌症与糖尿病均与发炎有关。
并未参与这项研究的美国知名注册营养师穆尔斯坦（Ilana Muhlstein）说，β胡萝卜素的第一大食物来源就是胡萝卜，β胡萝卜素是维生素A的前驱物，对于人体免疫系统非常重要。她强调，胡萝卜素的纤维质对于肠道健康、整体免疫力也有帮助，有利控制血糖，进而减少体内发炎情况，所以她建议，吃胡萝卜的好处比喝胡萝卜汁更大。
健康信息网站Health Shots依据营养师说法报导，适量摄取胡萝卜，有6大益处：
一、胡萝卜富含纤维有助调节饥饿感与血糖浓度，保持消化道健康。
二、胡萝卜富含可增强免疫力的抗氧化剂β胡萝卜素与维生素C，有助抵挡普通感冒与咳嗽。
三、β胡萝卜素与维生素C也能改善肤质，让皮肤更有光泽。
四、胡萝卜汁含有益生菌与胡萝卜纤维均有助控制血糖，适合糖尿病友摄取。
五、吃胡萝卜可摄取矿物质钾，有助控制血压，有益心脏健康；
六、胡萝卜含有维生素A、叶黄素、玉米黄素，这些都是护眼营养素，也有助降低黄斑部病变风险。
