The ancient Asian practice of fermenting soybeans and eating soy in the form of curds called tofu makes a healthy diet from a plant that eaten almost any other way would make people ill. The soybean itself is a notably inauspicious staple food; it contains a whole assortment of "antinutrients" compounds that actually block the body's absorption of vitamins and minerals, interfere with the hormonal system, and prevent the body from breaking down the proteins in the soy itself. It took the food cultures of Asia to figure out how to turn this unpromising plant into a highly nutritious food.
One of the most inauspicious days for washing was “Good Friday”.... Clothes hung out on that day would be spotted with blood & a story is told that Jesus cursed a woman who was washing clothes as he passed by on the way to Calvary .
