How parents' diet affects baby's health
CHROMOSOMES and genes contain the blueprint for your physical characteristics. But your parents' health and diet before you were conceived can also affect how your genes are expressed - and impact your long-term health.
There's a good explanation for this.
What's known as the "periconception period" covers the final stages of egg and sperm growth, fertilisation and embryo development before implantation into the uterus. During this time, the overall health of the egg, sperm and embryos are highly susceptible to changes in the environment.
Both under-nutrition (through deliberate calorie restriction) and over-nutrition (through diets high in calories, fats and sugars) in parents during this time can have major impacts on fertility and the long-term health of children.
