飞行员的合理营养,对于维护飞行人员的健康,防止疾病,提高飞行耐力,保证飞行安全和延长飞行年限都具有重要的作用。飞行人员的合理营养,是其特殊的工作特点决定的。首先,飞行对消化机能会引起较大变化。飞行中的低压、缺氧、噪声、振动和加速度等因素,通过神经和体液调节的影响,可直接作用于消化器官的本身。如人在1800米至2200米高度飞行,胃液分泌开始减少。在加速度作用下,胃液分泌受到强烈抑制,但以后又进入分泌增加期。低频率的振动能引起消化道功能障碍,出现食欲不振,胃部灼热感等。有人认为飞行人员溃疡病发病 Proper nutrition of pilots plays an important role in maintaining the health of pilots, preventing diseases, improving flight endurance, ensuring flight safety and extending flight years. The rational nutrition of pilots is determined by their special characteristics of work. First, the flight can cause significant changes in digestive function. Factors such as low pressure, hypoxia, noise, vibration and acceleration in flight can act directly on the digestive organs themselves through the influence of nerve and body fluid regulation. As people fly at altitudes of 1800 to 2200 meters, gastric secretion begins to decrease. Under the action of acceleration, gastric secretion is strongly inhibited, but then it enters the stage of excretion. Low-frequency vibration can cause gastrointestinal dysfunction, loss of appetite, burning sensation in the stomach. Some people think that pilots ulcer disease
