1酸碱失衡正常人血液的pH值为7.3～7.4,呈弱碱性,利于生理活动。一般情况下,人体具有自动的缓冲系统,能自身处理好酸碱的关系,从而使血液酸碱值保持在正常范围内,以达到生理上的平衡。但是,这种机体自身的缓冲能力是有限的,如果借着秋季凉爽,食欲大开,大吃山珍海味、大鱼大肉等呈酸性食物,超过了机体本身的耐受程度, 1 acid-base imbalance Normal blood pH of 7.3 to 7.4, was weakly alkaline, conducive to physical activity. Under normal circumstances, the body has an automatic buffer system that can handle the relationship between acid and base, so that the blood pH value maintained within the normal range, in order to achieve physiological balance. However, this body’s own buffer capacity is limited, if by the cool autumn, appetite, eating delicacies, big fish and other acidic foods, more than the body’s own tolerance,
