根据世界卫生组织报告,每年大约有1700万人死于心血管病,特别是心脏病和中风。
卢卡斯和他的同事比较了216个十几岁的青少年的健康状况,他们幼年时有的是母乳喂养的,有的食用的是营养配方奶粉。他们在兰斯特医学杂志上发表了他们的发现。
在坏胆固醇和好胆固醇的比例方面,吃母乳的青少年的比例低14%,并且他们的蛋白质积聚也比较低,而蛋白质积聚是导致心血管病的因素之一。
研究者还发现,不论孩子出生时的体重是多少,孩子在最初几个星期或几个月里长得越快,他们在今后的生活中的心脏病和中风的危险就越大。这种作用对男孩女孩都一样。
卢卡斯说:在新生期间喝越多的人奶,16年后胆固醇水平和血压就越低。[卫生类B]
6 Healthy Food
Street sellers, particularly in developing countries, supply large amounts of food for people on low incomes. This sector also employs some 6% ~ 25% of the work force, mainly women, in developing countries, and provides markets for agricultural and other produce. In many countries, however, the authorities are not willing to recognize it as a formal sector of the food supply system, they may ignore it In food control programs of even try to put and end to it.
There are two possible contaminants: pathogenic micro-organisms and hazardous chemicals. As far as micro-organisms are concerned, there is apparently no convincing evidence that street foods are more involved in the transmission of infection than foods obtained in, e.g., hotels. Studies in Egypt and else-where have found street foods to compare not unfavorably with hotel foods in respect of contamination with micro-organisms-some street foods were found to be contaminated with pathogens, but so were foods from four-and five-star hotels in the same area.
