It is now widely known that a mother's preconception diet plays a significant role in the health of her unborn child. The type of foods and nutrients the mother consumes at the time of conception can impact her child's lifelong health.
"While a child's genes are inherited directly from their parents, how these genes are expressed is controlled through 'epigenetic modifications to the DNA. One such modification involves tagging gene regions with chemical compounds called methyl groups and results in silencing the genes. The addition of these compounds requires key nutrients including folate, vitamins B2, B6 and B12, choline and methionine."
"Our results represent the first demonstration in humans that a mother's nutritional well-being at the time of conception can change how her child's genes will be interpreted, with a life-long impact."

Even though there is a lot of pressure put on the mother to take care of herself and consume the right foods prior to conception, it is quite easy to do if following the Paleo diet and lifestyle template. Paleo diet focuses on the consumption of nutrient-dense foods rich in healthy saturated fats and easily digested proteins from grass-fed and pasture raised animals. According to the authors of The Better Baby Book, such quality fats and proteins are critical for baby's brain growth as they make-up 12% (fat) and 8% (protein) of human brain.
"Studies of the health benefits of meat from cattle and lambs that ate the right feed (that is, grass) show that healthy red meat is one of the best choices for a pregnant woman."
