根据教科书《生物学:生理学的地球生命》,黑莓是一种由小核果组成的小水果。Like raspberries, they are not true berries and are called aggregate fruits. They contain large quantities of fiber, vitamin C and other important nutrients. As long as blackberries are clean, fresh and free of pesticides, they are safe for pregnant women.
黑莓和怀孕
黑莓在怀孕期间是安全的,只要孕妇采取正常的食品安全预防措施。吃黑莓之前要清洗,并且不要从灌木丛中采摘,除非是你自己种的。根据神经学家莉斯·艾略特的说法,杀虫剂和化肥会增加黑莓出生缺陷的风险,但如果黑莓经过适当清洗,则没有风险。避免吃不新鲜的浆果,因为它们容易枯萎或发霉。这些会引起腹痛和食物中毒。
黑莓的营养
黑莓能提供几种重要的营养和维生素,有助于健康怀孕。根据《生物学:地球上的生物生理学》,它们大约含有每日推荐摄入量的21%。Fiber contributes to overall health and well being and can help with constipation. They also contain about 10 percent of the recommended daily allowance of folate. Folate is of particular importance for pregnant women, because it helps prevent several birth defects and decreases the rate of miscarriage, according to Eliot. Other important nutrients in blackberries include vitamin C, vitamin K and potassium.
黑莓和能源
孕妇经常感到懒散,尤其是在怀孕后期。像黑莓这样的水果是能量的重要来源。儿科医生威廉·西尔斯建议孕妇每天吃五到六份新鲜水果。水果能增加能量,脂肪和钠含量低,有助于胎儿大脑发育。
食品,以避免
怀孕的女性经常会对那些需要避免的事情感到困惑。一般来说,女性在怀孕期间应该避免的食物只有几种。这些食物包括软奶酪、熟食肉、生鸡蛋和酒精。虽然每周吃一次鱼没什么问题,但大量食用某些鱼类,特别是金枪鱼和鲑鱼,会使发育中的胎儿暴露在汞之下。向你的医生咨询进一步的饮食建议。
