甜食过量与食盐过量同样有害。譬如吃点心或饮桔汁等过量,就会使血糖增高。人体为了不使血糖含量增多,胰脏就得开足马力分泌胰岛素。长此以往,就会形成习惯,既使不吃糖也照样分泌胰岛素,形成血糖值低;血糖值低,人体自然受不了,就又得吃糖或甜食。进食后,胰脏又分泌胰岛素;如此恶性循环,可能导致糖尿病的发生。甜食过量不仅能引起糖尿病,而且容易引起癌。更有甚者,据一位精神科医生的报告,精神分裂症患者最爱吃糖果、甜点心,爱饮咖啡和吃水点心等甜食,所以甜食过量与精神病也有一定关系,不可不引起重视。在甜、酸、咸、苦四种味道中,大多数人最爱吃甜食。人如此,动物也如此。例如,有些虫和鸟就专吸吮树干上的甜汁。
Overdoses are just as harmful as overdoses. For example, eating too much dessert or drinking orange juice, will make blood sugar increased. In order not to increase the body’s blood sugar levels, the pancreas has to open enough to secrete insulin. Over time, it will form a habit, even if not sugar also secrete insulin, the formation of low blood sugar; blood glucose is low, the body naturally can not stand, they have to eat sugar or sweets. After eating, the pancreas also secrete insulin; such a vicious cycle may lead to the development of diabetes. Overdose can not only cause diabetes, but also easily lead to cancer. What is more, according to a psychiatrist’s report, schizophrenic patients most like to eat sweets, sweet snacks, coffee and snacks to eat sweets and other desserts, so there is a certain relationship between sweets and mental illness, we must pay attention. In sweet, sour, salty, bitter four kinds of taste, most people like to eat sweet food. So, animals, too. For example, some insects and birds specialize in sucking the sweet juice from tree trunks.
