FOOD FOR FERTILITY
We’re all different…
But food affects us all.
Wherever we live...
And whatever we do.
This woman is desperate for a baby
and willing to try almost anything to get pregnant.
Can she improve her chances
through the food she eats,
and help the baby stay healthy
running up to the birth?
From the hit and miss nature of conception,
to all the dangers associated with pregnancy,
it’s often amazing
that any babies are born at all.
When you’re pregnant,
what you eat goes straight into your baby,
so if you like any of these foods
then stop eating them right now.
Raw eggs can contain salmonella,
and uncooked pate or soft cheeses can carry listeria.
Both dangerous bacteria.
Fish, in moderation,
is generally good for you,
but raw fish can contain mercury
and affect the babies developing nervous system.
Finally, cut down on alcohol and caffeine.
Better to be safe than sorry.
But when it comes to babies,
food is a double edged sword.
There are foods that can help this couple start a family?
The advice of modern science is fairly simple.
Go for a healthy diet.
Fruit and vegetables for those essential vitamins,
and milk or yoghurt to help top up her calcium levels.
It’s not just women though.
Plenty of foods can affect male fertility.
The occasional steak
could reduce birth defects in her
and keep his sperm count high.
But remember to keep it lean.
Too much excess body fat can damage sperm
and cause problems later down the line.
Surprisingly, coffee,
which can be a problem for women,
might actually improve male fertility
by making sperm less sluggish.
So with fertility sorted out,
the next thing is to get you in the mood.
Over the years one culture or another
has used near enough
every food available to boost fertility.
Some are purely based on the idea
that foods with a passing
resemblance to sexual organs must improve them.
Others have a little more to them.
Oysters have been an aphrodisiac
for generations,
and it turns out there is some truth in it after all.
Packed full of zinc,
they may not actually get you in the mood,
but they will help to improve both her fertility
and his sperm production
As usual it’s the more attractive
and suggestive foods
that get all the aphrodisiac credit.
But spare a thought
for those less attractive unsung heroes.
Perhaps surprisingly,
celery and beetroot
might actually be more effective.
Celery contains
the male hormone androsterone,
thought to stimulate arousal in women.
And beetroot has high levels of Boron,
important in the production of human sex hormones.
Once you’ve become pregnant
your tastes can change,
and you might find yourself craving foods
you’d never considered before.
They could be for something bizarre,
but harmless,
or you might find yourself with an
uncontrollable desire to eat coal.
This desire to eat non-food items is called pica
and it can cause real health problems.
After all, whatever you eat
enters your baby’s bloodstream too.
So whether you have cravings or not,
eat smart while you’re pregnant
and your baby should have
a much better start in life.

繁衍后代的食物
每个人都是不同的个体
但都受食物影响
不论我们住在哪里
也不论是什么职业
这位小姐很想生个小孩
只要能怀孕什么方法都愿意尝试
她能靠摄取的食物提高受孕机率
同时协助宝宝健康发育到出生吗？
从是否命中的概念看来
就怀孕的相关危险而言
婴儿诞生可说是个奇迹
怀孕时摄取的食物会直接传送给胎儿
如果你喜欢这些食物
最好现在就戒了
生蛋可能含有沙门氏菌
没煮熟的软质乳酪可能含有李氏杆菌
这两者都是危险的细菌
适量摄食鱼类通常对身体很好
但生鱼可能含有汞
影响宝宝发育中的神经系统
最后是减少酒精和咖啡因摄取量
最好还是小心为上
但对婴儿而言
食物有好处也有坏处
有什么食物能帮助这对夫妻建立家庭？
现代科学的建议相当简单
建立健康的饮食习惯
水果和蔬菜拥有必需维他命
牛奶或优格可增加体内的钙
当然不只是针对女性
也有很多食物可影响男性生殖能力
偶尔吃些牛排可减少先天缺陷
及提高精子数目
但要记得维持身材
体内脂肪过多可能破坏精子
以及造成其它问题
令人惊讶的是对女性可能造成问题的咖啡
却可能增加精子活动力提高男性生殖能力
解决生殖能力问题之后
接着是如何营造气氛
自古以来，各种文化尝试过
各种食物来提高生殖能力
有些食物只是因为像性器官
就被认为能提高性能力
有些则不只如此
牡蛎一直被视为催情食物
现在认为确有几分道理
牡蛎含有大量的锌
或许不能营造气氛
但有助于制造精子和提高生殖能力
通常较有吸引力或暗示性的食物
被认为具有催情作用
但也要留意不起眼的无名英雄
令人惊讶的是，芹菜和甜菜其实可能更有效
芹菜含有男性荷尔蒙雄固酮
可刺激女性
甜菜则含有大量的硼
对制造人类性荷尔蒙相当重要
怀孕后味觉会改变
往往会吃以前从来不吃的东西
可能是某些奇特，但无害的东西
甚至可能会想吃煤炭
这种吃非食物的欲望称为异食癖
可能造成健康问题
毕竟不论你吃下什么东西
都会进到宝宝体内
因此不论你吃不吃东西
怀孕时吃东西应该特别小心
宝宝就能赢在起跑点上
