Nutrition in the womb is the process that delivers to
the fetus what it needs to grow and develop into a healthy
baby. A fetus receives its nutrition from two sources.
The first source of nutrients is from the mother’s diet
before and during pregnancy. Most people understand this.
The fetus receives the nutrition
it needs to grow not only from what the mother eats during
pregnancy but from the mothers own body.
The least known and probably more important source of
nutrients is the mother’s body. All bodies undergo a
turnover process. Turnover is the ever-changing state
of breakdown and renewal of muscle, fat and bone which
releases protein, fat and calcium into the bloodstream.
In a pregnant woman these nutrients are important sources
of food for a growing baby. Mothers who have good turnover
rates for themselves are able to provide well for their
babies. A mother acquires her body composition and turnover
throughout her whole lifetime as a fetus, child, girl,
adolescent and adult. The mother’s turnover and her diet
work in harmony to provide nutrition in the womb through
the placenta.
The placenta, which is part of the baby that attaches
it to the womb, captures nutrients from the mother’s
blood and transports them to the baby. The growth of
the placenta and the food it supplies are the key to
health for a lifetime. The placenta has three functions. It is the gate between mother and
baby, transferring food from the mother and waste from the baby; it makes hormones that
signal to the mother what the baby needs; and it protects the baby from the mother’s
immune system, which could attack the baby because it is "foreign" to the
mother’s body because half of its genes come from the father. The development of
the placenta begins when the embryo implants into the lining of the mother’s womb,
on the eighth day after conception. The organ becomes fully functional in the tenth week
of pregnancy. At birth its surface is oval in shape. It seems that the tissue along the
length of the surface has different functions to tissue along the breadth.
