现代人的营养不足并非缺吃少喝引起的,而是食过分精制食品和不注意营养平衡造成的。所以我们除了从身体内部反应得知营养不足外,首先可从眼、鼻、口、指甲和头发等部位观察到一些端倪。这些部位所表现出的信号,经常是每个医生在诊治时首先问及和留意的重点。作为普通人若对这些信号能略知一二,将有助于调节人体的营养状况。 Modern lack of nutrition is not caused by eating less drink, but eating too much refined food and not pay attention to nutritional balance caused. Therefore, apart from the lack of nutrition in our body’s internal response, we can first observe some clues from the eyes, nose, mouth, nails and hair. The signals that these areas show are often the first thing every doctor asks and looks into at diagnosis and treatment. Being an ordinary person who knows a little about these signals will help to regulate the nutritional status of the human body.
