Before the Iron curtain fell in 1989, microwave oven were not considered safe with Russia’s microwave radiation safety threshold being 1,000 times lower than that in the the western world.
“Microwaves absolutely decimate the nutritional value of your food, destroying the very vitamins and phytonutrients that prevent disease and support good health. Previous studies have shown that as much as 98% of the cancer-fighting nutrients in broccoli, for example, are destroyed by microwaving.
To understand why, you have to understand the nature of vitamins and phytonutrients (plant-based nutrients). These are very delicate molecules which are fragile. They are easily destroyed by heat, which is why raw plant foods contain more plant nutrients than cooked foods. Carotenoids, antioxidants and other molecules like DIM (in broccoli) or anthocyanins (in purple corn) are all easily destroyed by microwave energy.”
