Hmmm.. I'm not sure why you would think that housewives would need to consume fat any more than another woman - or a house husband, for that matter!?
Consumption of fat is important as it gives us energy. It is needed for the development and growth of cells, and is stored to continue to do this function when there is a shortage of food.
It provides insulation to protect our organs from the cold, and some fats like omega 3, found in oily fish, even help to boost our brain power.
I think it's safe to say that these functions are required by all human beings, regardless of whether they spend their days taking care of children and a household, or are CEO of high flying corporation.
Fat is one of the essential aspects of maintaining our health and well-being. For everyone, not just housewives...
