最近,据营养学家研究指出:经常单独进餐的人容易患胃溃疡和十二指疡溃疡。那么,这是什么原因呢?
让我们先看看一家进餐的状况:当一家人心情舒畅地围着餐桌吃饭时,大家的心态是平和的,每个家庭成员咀嚼着自己爱吃的美食,有说有笑,即交流了感情,又享受了佳肴,气氛融洽,十分温馨。在这种充满亲情的环境下共进午餐(或早、晚餐)时,心情轻松愉快。在人们精神愉悦时,其胃液的分泌也相对旺盛,可促使肠胃加快蠕动,使食物尽快地消化和吸收,消化系统也就保持畅通无阻。
而一个人单独进餐情况就大不相同了:一个人吃饭,因为没有伴,吃起来很慢,有的一边看书报一边吃饭,有的一边看电视一边咀嚼,有的则一边杨关不愉快的事情或没完成的工作一边进餐,默默地吃,慢慢地嚼,一餐饭往往从热的吃到冷,要化两顿饭的时间。单独进餐的人心情不开朗,容易产生紧张、烦恼、气愤等不良情绪。而不良的情绪会对消化系统会造成极大伤害。它能使人体胃肠的血管收缩,阻碍正常的消化活动,抑制胃中消化液的分泌,这对胃部来说,是十分危险的征兆。
我们知道,从胃壁分泌出的胃液中含有盐酸和胃液素,胃液可以使食物消化、溶解。那么,胃液为何不会把胃部溶化呢?这是因为,胃壁在分泌胃液的同时,也不断地分泌粘液,用粘液来保护胃壁不受胃液的侵害。但是,当一个人情绪不稳定,甚至出现孤独、苦闷、紧张、烦恼或气愤时,胃壁的血管便自动收缩,血液循环变慢,保护胃壁的粘液的分泌也大为减少了,而胃液的分泌并不减少。在这种情况下,极容易导致胃壁穿孔,造成胃溃疡或十二指肠溃疡。胃溃疡有的是长年累月单独进餐形成的,也有的人是在受到了沉重打击的时候,在极短的时间内造成胃穿孔的,医学上称它为“突发性胃溃疡”。
所以说,有条件的朋友,最好和家人、朋友或同事一道进餐,大家说说笑笑、轻松愉快,既吃得开心,又吃得健康,何乐不为?
