減嬰兒遺傳病 孕婦要均衡飲食

基因不一定決定命運，有外國研究發現，人的健康有八成在幼童期受環境因素影響，建議婦女把握懷孕前六個月關鍵期，忌吃太多或太少，減低嬰兒未來患有糖尿病等遺傳病風險。

外 國接連有大學如哈佛大學等發表研究，發現孩子健康有20％在受孕時由遺傳基因決定，其餘在幼童期受環境因素影響。根據「ENP」（早期營養編程科學），把 握兒童「前六後六」，即懷孕前六個月至幼兒六歲成長關鍵期，若孕婦攝取足夠營養素，可以減低孩子患上一些遺傳病風險如濕疹、糖尿病等。

 
把握懷孕前六個月關鍵期

註冊營養師張智良指，污染物如塑膠添加劑雙酚A，會啟動致肥基因，但老鼠研究發現進食維他命B12 等可抵銷效應。他指有研究發現荷蘭在1944年發生大饑荒時出生的嬰兒，到50歲時部分出現高血壓等徵狀；另有研究香港97年後出生的8,000個小童， 他們7歲時體重指標較高，而父母教育程度愈高，孩子愈重，反映孕婦懷孕時吃太多或太少均影響孩子健康。

張續說，葉酸在懷孕六至八星期時攝 取效果最佳，但婦女因多不知已懷孕而錯過，因此在計劃懷孕前應增攝取量；若本身超重，生育前亦宜應先減肥。他補充，孕婦應避免常吃燒烤食物，及少吃大魚， 減少攝取水銀等有害物質。 婦產科醫生則指，中國人有不少錯誤觀念，如孕婦要吃雙份食物，及不宜做運動等；此外亦不宜節食，否則孩子長大後回復正常進分量，亦會導致癡肥，孕婦 超重10至15公斤已足夠。

DHA Pregnanc

Adequate DHA intake is of utmost importance to expectant mothers. It has been shown that DHA plays a vital role in fetal brain and retinal development. According to international recommendations, the minimum daily requirement of DHA for pregnant or breast-feeding women is 200 milligrams, which is equivalent to a weekly intake of 1-2 portions of deep-sea fish that is rich in DHA.


However, pregnant ladies may find it difficult to eat fish because of alterations in taste and appetite. Furthermore, the concern of marine pollution is a real one, and expectant mothers may fear that inadvertent intake of heavy metal like mercury that comes with deep-sea fish may affect their babies.


Indeed there are other sources of DHA, among them are algae. Microalgae, from which algae oil DHA is extracted, are at the very start of the food chain. With a closely monitored production environment, algae oil is a safe source of DHA for expectant mothers.
