Impact of Income on Nutrient Intakes: Implications for Undernourishment and Obesity

The relationship between income and nutrient intake is explored. Nonparametric, panel, and quantile regressions are used. Engle curves for calories, fat, and protein are approximately linear in logs with carbohydrate intakes exhibiting diminishing elasticities as incomes increase. Elasticities range from 0.10 to 0.25, with fat having the highest elasticities. Countries in higher quantiles have lower elasticities than those in lower quantiles. Results predict significant cumulative increases in calorie consumption which are increasingly composed of fats. Though policies aimed at poverty alleviation and economic growth may assuage hunger and malnutrition, they may also exacerbate problems associated with obesity.

德国慕尼黑的啤酒节

每年9月底,慕尼黑都有一个充满德国民族文化色彩的October Festival啤酒节.从1810年开始,迄今为止,已经举办170多届.200多年前,德国是一个群侯割据的松散王朝.阿尔卑斯山脚下的巴维日亚区域历来以农业为主,五谷丰登,牛羊成群.1810年,嗜酒成性Maximilian王侯为了庆祝自己的婚礼,广邀各地英雄好汉到慕尼黑来进行赛马竞技.谁知一场马术比赛却演变成啤酒大狂欢.此后,每年9月的第三个星期天便被定octobeffest狂饮节(亦即啤酒节),为期三周.
