“Major changes have taken place in the food supply over the last 100 years, when food technology and modern agriculture led to enormous production of vegetable oils high in omega-6 fatty acids, and changed animal feeds from grass to grains, thus increasing the amount of omega-6 fatty acids at the level of LA (from oils) and arachidonic acid (AA) (from meat, eggs, dairy).
“This led to very high amounts of omega-6 fatty acids in the food supply for the first time in the history of human beings. Traditionally, animals grazed. Grass contains ALA (omega-3), whereas grains, corn and soya (which are now fed to animals) are high in LA (omega-6). This imbalance in the amount of omega-6 and omega-3 fatty acids is a new phenomenon that was never a part of human evolution.
“Human beings evolved on a diet that had equal amounts of omega-6 and omega-3 fatty acids. This balanced ratio of omega-6 to omega-3 is critical to human development during pregnancy and lactation, in the prevention of chronic diseases and in their management.
“The typical Western diet now provides an omega-6 to omega-3 ratio of around 16:1. High dietary intake of omega -6 fatty acids as occurs today leads to increases in white adipose tissue and chronic inflammation, which are the ‘hallmarks of obesity’.”
Many mothers-to-be are victims of this ratio imbalance, with a direct impact on their unborn children.
