Studies Show Microwaves Drastically Reduce Nutrients In Food
I can remember the days growing up in the 1950′s and 1960′s, when we prepared foods without a microwave oven. Water was boiled on the stove. Chicken was baked in an oven. Vegetables were steamed, baked, or sautéed. Food was whole and fresh. Even a TV dinner was baked in the oven, which took about 15 minutes to warm. And then, modern science and technology brought us the microwave oven that could heat food rapidly, from 30 seconds to a couple of minutes.
The industry has claimed that microwave cooking protects the nutrient content of foods. Somehow, in tasting foods that came out of a microwave oven, the texture was changed as was the flavor. Foods cooked or reheated in microwave ovens became rubbery and lacked the savory smells and layered flavors that come from cooking foods slower and longer.
Nevertheless, people bought the convenience aspect, the speed, the simplicity of heating and eating prepared foods. The science, which has been supported by the food industry, has continued to claim the health benefits of microwave cooking. Recently, published data from reliable sources questions the health benefits of microwaved food.
Does this mean an occasional microwaved meal will be harmful? Not likely. But what about a steady diet of eating foods cooked at such a high heat? Do the sensitive compounds in food, such as amino acids, fatty acids, vitamins and phytonutrients change? It appears so. Read on to follow the scientific literature surrounding the depletion of our soil, foods, and health as a result of modern farming, food processing, microwave cooking, and not eating enough fresh, natural, uncooked, organic whole foods.
- Three recent studies of historical food composition have shown 5-40% declines in some of the minerals in fresh produce, and another study found a similar decline in our protein sources (1)
- A 1999 Scandinavian study of the cooking of asparagus spears found that microwaving caused a reduction in vitamins (3)
- In a study of garlic, as little as 60 seconds of microwave heating was enough to inactivate its allinase, garlic’s principle active ingredient against cancer (5)
- A study published in the November 2003 issue of The Journal of the Science of Food and Agriculture found that broccoli “zapped” in the microwave with a little water lost up to 97% of its beneficial antioxidants. By comparison, steamed broccoli lost 11% or fewer of its antioxidants. There were also reductions in phenolic compounds and glucosinolates, but mineral levels remained intact (6).
- A recent Australian study showed that micro- waves cause a higher degree of “protein unfolding” than conventional heating (2)
- Microwaving can destroy the essential disease-fighting agents in breast milk that offer protection for your baby. In 1992, Quan found that microwaved breast milk lost lysozyme activity, antibodies, and fostered the growth of more potentially pathogenic bacteria (4).
