            咖啡这样喝才健康 Coffee drinks healthier in this way ??? ??? ?? ?? ????





            一些上班族有早上空腹喝咖啡的习惯,觉得能排除毒素、振奋精神,还能起到减肥效果。然而,山医大一院消化内科副主任医师李晓丽介绍,咖啡因具有兴奋心肌的作用,对咖啡因敏感的人饮用咖啡后,会导致血液中咖啡因浓度急剧上升,从而刺激中枢神经系统,造成眩晕、心跳加快、兴奋、不安等精神症状。咖啡因可致房室结的有效不应期缩短,从而引起各种快速性心律失常及早搏。因此,如果饮用咖啡后心慌、心悸、眩晕等,应当减少或避免咖啡因摄入。处于亚健康状态的人、经常熬夜的人不宜长期大量喝咖啡,高血压、心脏病患者也不宜喝咖啡。

            Some office workers have the habit of drinking coffee on an empty stomach in the morning. They feel that they can eliminate toxins, stimulate their spirits, and also have the effect of losing weight. However, Li Xiaoli, deputy chief physician of digestive medicine, Shandong Medical University First Hospital, said that caffeine has the function of exciting myocardium. After drinking coffee for people sensitive to caffeine, the concentration of caffeine in the blood will rise sharply, thus stimulating the central nervous system, causing mental symptoms such as dizziness, rapid heartbeat, excitement and restlessness. Caffeine can shorten the effective refractory period of atrioventricular node, thus causing various tachyarrhythmias and premature beats. Therefore, if you drink coffee after panic, palpitation, dizziness, etc., should reduce or avoid caffeine intake. People in sub-health state and those who often stay up late should not drink coffee in large quantities for a long time, and those with hypertension and heart disease should not drink coffee.

            李晓丽说,空腹喝咖啡之所以会有减肥效果,是因为肠胃经过一夜休息后,早晨空腹喝咖啡时,咖啡因会刺激肠胃,进而影响早餐正常的营养吸收,最终导致体重减轻。但这是非常不健康的做法,特别是有胃溃疡和烧心症状的人,要少喝或尽量不喝咖啡,否则会加重胃肠不适。

            Li Xiaoli said that the reason why drinking coffee on an empty stomach can reduce weight is that caffeine stimulates the stomach and intestines when drinking coffee on an empty stomach in the morning after a night's rest, which affects the normal nutritional absorption of breakfast and eventually leads to weight loss. But this is very unhealthy practice, especially those with gastric ulcer and heartburn symptoms, to drink less or try not to drink coffee, otherwise it will aggravate gastrointestinal discomfort.

            另外,咖啡加奶可避免钙损失。“咖啡中的咖啡因有利尿作用,会增加尿液中钙质的排泄,以及促进小肠中钙质的分泌,有可能导致骨质疏松。”李晓丽说,日常食物中缺乏摄取足够的钙或是不经常动的人,特别是更年期后的女性,缺少雌激素会造成钙质流失,这种情况下再摄入大量的咖啡因,可能会导致骨质疏松。平均每杯咖啡中的咖啡因只会增加2~3毫克的钙流失。如果喝咖啡的时候添加纯牛奶,那么从牛奶中获得的钙用来弥补喝咖啡所造成的钙损失还绰绰有余。

            In addition, coffee with milk can avoid calcium loss. "Caffeine in coffee has a diuretic effect, which increases the excretion of calcium in urine and promotes the secretion of calcium in the small intestine, which may lead to osteoporosis." Li Xiaoli said that people who lack enough calcium in their daily diet or who do not move regularly, especially women after menopause, lack of estrogen can lead to calcium loss. In this case, taking a large amount of caffeine may lead to osteoporosis. On average, caffeine in a cup of coffee increases calcium loss by only 2 to 3 mg. If pure milk is added to coffee, the calcium obtained from milk is more than enough to compensate for the loss of calcium caused by coffee consumption.
