回味地瓜

地瓜，正名番薯（学名：Ipomoea batatas (L.) Lam.）。别称甘薯、红薯、山芋、红苕等等，国家规定为粮食。明朝李时珍在《本草纲目》中记载：“番薯具有补虚乏、益气力、健脾胃、强肾阳之功效”。 薯块中含有丰富而特殊的维生素C、维生素E和钾元素；还有胶原粘液蛋白，这种物质能保持人体动脉血管壁的弹性，有效地防止动脉血管粥样硬化。所以，吃地瓜对人体大有好处。多吃容易引起烧心、吐酸水、肚胀排气等现象，一般要和米面搭配着吃。要注意有胃病的人，吃了会不舒服。

在那艰苦的岁月，稻米、麦子少，而地瓜、萝卜能丰收，人们几乎天天吃地瓜或者其制作品，如：地瓜饭、地瓜干、地瓜粉条、烤地瓜等等，靠地瓜度过了苦难的日子。如今，大米、面粉随便买，许多人对地瓜嗤之以鼻，甚至一年到头不吃地瓜以荣耀。

也许有剩饭不想吃，倒了又可惜。那就做地瓜稀饭，好吃，有人觉得是美味。方法很简单：买好的地瓜，去皮洗净，切成小块，放适量水在锅里煮熟，用筷子一夹就烂，倒入剩饭，水不可太少，烧开就行了。吃饭的时候，吃点主食、地瓜稀饭，吃点炒菜，顺便吃点咸菜、榨菜之类，便宜又实惠，饱腹感明显，有精力。
