婴儿食用营养成分过高奶粉或致日后肥胖

奶粉喂养的家庭要注意一下营养过剩的话题。因为婴儿的营养并不是越丰富越好,他有有效吸收率。据英国的一项研究结论,如果宝宝长期食用营养成分过高的奶粉,他们在儿童期的脂肪含量可能明显高于同龄人,成年后更容易长成胖子。说白了,这个研究结果是支持母乳喂养的,母乳喂养导致营养过剩的可能性较小。

英国伦敦大学学院等机构的研究人员,在新一期《美国临床营养学期刊》上报告说,他们跟踪调查了200多名婴儿的成长情况。其中部分婴儿采用增强营养的奶粉喂养,另一部分食用普通奶粉。结果发现,前一组婴儿成长到5岁至8岁时,体内脂肪含量比后一组要高出22%至38%。

参与该研究的科研人员指出,儿童脂肪含量较高可能成为日后肥胖的诱因。此前有研究发现,约20%的成年肥胖者与其幼年时过度喂养有关。

Researchers at the UCL Institute of Child Health have demonstrated for the first time in humans that feeding babies enriched milk led to statistically significant increases in body fat at age 5-8 years.

The new study is published today online in the American Journal of Clinical Nutrition. This key finding of the link between overnutrition in infancy and body fat was independent of confounding factors such as maternal Body Mass Index. Fat mass in childhood was 22–38 per cent greater in infants randomised to nutrient-enriched versus standard formula.

As increased fat in childhood is a significant risk for obesity in adulthood, the public health implications are profound. The study confirms previous estimates that more than 20 per cent of adult obesity might be caused by overnutrition, or other early excessive weight gain in infancy.

The research, led by Professor Atul Singhal, UCL Institute of Child Health, looked at two different randomised, double blind, controlled trials, in which children small for their gestational age were randomly assigned a nutritionally enhanced formula milk, or a standard formula.

At that time it was considered ethically appropriate to give such babies nutritional enhancement in line with then current practice, a practice which may now have to be re-evaluated. Indeed, the later study was terminated on ethical grounds because of the strength of the link between early over-nutrition and later obesity. The two studies used different methods of testing body fat which, however, produced similar results. The link between over-nutrition and body fat was stronger in the study where over-nutrition took place over a longer period.

Professor Singhal said “This study robustly demonstrates a link between early nutrition and having more fat in later life in humans – a finding suggested by previous studies and confirmed in many other animals. Our findings are strong, consistent, show a dose-response effect, and are biologically plausible.

“Immediately, it raises the issue about the best way to feed those children small for gestational age, which should now be evaluated in the light of all current evidence. In public health terms, it supports the case in the general population for breastfeeding – since it is harder to overfeed a breastfed baby. And it will undoubtedly be of interest to formula milk companies wishing to improve their products.”
