从营养价值角度谈啤酒

 　　Beer is a low-alcohol beverage¹ obtained by fermentation of malt. The main ingredients involved in the set are: malt, yeast², hops³ extract (plant bitter taste) and carbon dioxide, which is what makes soda⁴.

　　One positive aspect is that the beer has less alcohol content compared with wine or other spirits, but let's nutrition.

　　The beer contains a small amount of vitamins and minerals derived⁵ mostly from yeast. Yeast is rich in B vitamins, minerals and trace elements, however, yeast in beer is very dilute⁶, so that the vitamins are made in small quantities.

　　It contains vitamin B2, B6 and folate, 2 to 3% of the recommended daily amount of vitamin C and E are completely absent in the beer.

　　One thing that might interest them vegans is that non-alcoholic beer can be found vitamin B12.

　　It has 1 to 2% of the recommended daily allowance of calcium⁷, phosphorus, magnesium⁸ and potassium.

　　Beer is one of the best sources of chromium, this trace element deficiency can cause the onset⁹ of diabetes¹⁰.

　　The dark beer is rich in antioxidant flavonoids similar to those in red wine, so as to exert a protective effect on the heart. But do not rule out negative effects on the heart muscle and other organs.

　　These are some of the nutrients¹¹ that have but we can not ignore the fact that habitual¹² consumption promotes the development of rectal cancer, gout, and migraine. Therefore their intake¹³ should be moderate and occasional.

　　啤酒是一种发酵麦芽形成的低度酒精饮料。主要成份是麦芽，酵母，蛇麻草(一种苦味植物)提取物及用于制作苏打水的二氧化碳。

　　相比酒或其他烈酒，啤酒的可取之处是酒精含量要少很多，不过咱们今天从啤酒的营养角度出发。

　　这种酒当中含有少量的维生素和来自酵母出的大部分矿物质。酵母富含B族维生素，矿物质和微量元素。然而，啤酒中的酵母被稀释，以致于维生素只有很小的含量。

　　在啤酒含有的维生素B2，B6和叶酸中，2% —3%的每日人体所需维他命C和E已经完全消失。

　　你可能感兴趣的一件事是，不含酒精的啤酒中发现了维生素B12。

　　啤酒当中还有1%—2% 的每日人体所需的钙，磷，镁，钾。

　　同样，啤酒是铬的最好来源，该微量元素缺乏可引起糖尿病的发病。

　　黑啤酒当中含有丰富的类似于红酒的抗氧化剂类黄酮，这对保护心脏有好处。但不排除心脏肌肉和其他器官的负面影响。

　　这些是啤酒的营养，但我们不能忽视一个事实，那就是习惯性喝啤酒容易引起直肠癌，痛风及偏头痛。因此必须适度和偶尔摄入啤酒。
