Diet for Pregnancy (Part 4)



There are more common health problems during pregnancy such as nausea and vomiting. It is common but tends to reduce risk of miscarriage. The cause may relate with increased level of human chorionic gonadotropin, progesterone, estragon. Normally, it occurs during the beginning of fourth week but will start disappear on 10th week. However, frequent vomiting can lead to dehydration, electrolyte imbalance or weight loss as the loss of appetite towards food intake. Thus, you should try separating the liquid and solid food intake, select well tolerated food such as hard-boiled eggs, popcorn, yogurt, crackers and noodles or porridge. It is advised to ingest small meal frequently, do not get bed with full stomach, and avoid foods heartburn (spicy, high fat, beans, citrus, peppermint, coffee). Besides, avoid any artificial sweeteners, alcohol, recreational drugs, and cigarettes with the potential of harming your soon to be conceived baby.

在怀孕期间也有一些常见的健康问题:
恶心和呕吐是常见的,可是能帮助减少流产几率。引发这现象的原因是激素,孕酮,雌激素水平增加有关。呕吐通常都发生在第四个星期开始至第十个星期,严重可导致脱水,电解质紊乱。因此,把固体与液体状食物分开饮食,避免触发恶心气味的食物,选择易消化食物如水煮鸡蛋,酸奶,饼干,面食类等食物。

胃灼热归因于胃肠道肌肉松弛的孕激素,降低食管括约肌放松,使胃内容物推入食道。因此,是建议少量多餐(56餐)经常摄取小餐,不要吃的饱饱就睡觉(容易倒流),避免饮食会造成胃灼热的食物,这包括辛辣,高脂肪,豆类,柑橘,薄荷,咖啡等。此外,在怀孕期间也建议避免摄取任何人工甜味剂,酗酒,嗑药,和香烟都可能伤害你的婴儿。

Human milk feeding is adequate as the sole source of nutrition for up to age 6 months providing that the maternal diet and reserves are adequate plus a sufficient quantity is transferred to the infant. The recommended energy intake during the first 6 months of lactation is an additional 500 kcal with extra 20g protein which means a total of 2300 Kcal under the assumption that 170 kcal/d will be mobilized from energy stores accumulated in pregnancy. The recommended energy intake after 6 months is reduced to an additional 400 kcal/d with extra 15g protein which is 2000-2200Kcal because milk production rates decrease to 600 mL/d. However, this energy calculation needs to be calculated based on different weight. Normal weight can be calculated according to the above energy recommendation while overweight or obese person should maintain a 1600-1800 Kcal for further weight gain prevention and able to lose weight effectively. Of course, protein is needed to maintain adequately for the quality of milk production and calcium intake.

哺乳期间的营养需要比起怀孕时的营养更为重要。婴儿从出生到大概六个月时,体重可达到出生体重的一倍,这全依赖于母乳的营养。所以,这六个月母亲所摄取的营养是非常重要的,必须确保饮食营养是充足让婴儿吸收,因为婴儿只依靠母乳得到营养。因此,建议在哺乳期的前6个月摄入额外的20克蛋白质,增加500卡路里,这意味着每天摄取将在2300卡路里。 6个月后推荐的能量摄入将减少,只需要额外15克蛋白,这是2000-2200Kcal。因为牛奶产量率会减少到600毫升/天。然而,这种能量的计算还需要根据不同重量计算。正常体重可以根据上述能源的建议,而超重或肥胖应保持16001800年为预防体重增加,同时有效地进行减肥。 当然充分的蛋白质是必要的,尤其从牛奶方面因含钙量也很重要。

At present, our information about the role of dietary supplementation in lactation is limited. A balance diet during lactation is important rather than then supplements. A supplement of vitamin D (10 g/d) is recommended for women who avoid milk and other foods fortified with vitamin D. Similarly, a supplement of vitamin B-12 (2.6 g/d) is recommended for lactating women who are complete vegetarians.

就如上述所说,产妇的营养可以影响母乳的品质。目前,我们对在哺乳期的膳食补充剂的资料是有限的。哺乳期间的饮食平衡才是最重要的,而不是依赖补充剂。补充维生素D10/天)是建议给不喝牛奶和其他乳制品的产妇。同样的,素食产妇也可以摄取维生素补充维生素B-122.6/天)。
