Is zapping food in microwave safe?
I have thrown out my microwave for safety reasons and concerns and was wondering how a convection oven works compared to a microwave? How safe is it for warming my baby's milk?
The standard oven and the convection oven, work similar to each other. The notable difference in the convection oven is that it has a fan that increases the distribution of the heat molecules providing heat to all areas more evenly and faster. Because of the fan and the efficiency of the heat circulation, a lower temperature is usually required, thereby conserving energy. Meats do very well cooked in a convection oven, and because of the lower heat, the meat tends to be juicier! Microwaves, on the other hand, penetrate and are absorbed by food products and liquids. Microwaves are a form of electromagnetic radiation in which energy penetrates the food and its power is gradually absorbed, or lost, to each layer of molecules. The rate of energy loss and depth of penetration vary depending on the food. Hence, microwaved food is quite often found cold in the center. The Journal of the Science of Food and Agriculture has stated that research shows that microwaving food does cause a significant decrease in the nutritive value of food. Dr. Joesph Mercola, licensed physician and surgeon, states that the water molecules rotate rapidly in the microwave and in the food in high frequencies, which creates molecular friction that heats the food. This friction causes the molecular structure in the food to change and, as a result, diminishes the nutrient content in the food. The powerful bacteria-fighting agents in breast milk are also destroyed by microwave heating. A study published in the Journal of Pediatrics examined the common practice of using a microwave to heat human milk. Researchers found that heating milk for 30 seconds had greater E.Coli growth - 18 more times than the breast milk not heated in a microwave. Microwaving at low temperatures also dramatically decreased lysozyme activity and also promoted the growth of harmful bacteria for babies. Also of concern is the amount of radiation that may leak from the microwave oven. The Food and Drug Administration warns that you should NOT stand near or in front of the microwave when in use. It is especially important that children follow this rule since their bodies absorb radiation more easily than adults. Just as a note: I microwaved a potato eight years ago and it still looks the same-no mold, no growth, no smell! Hum!
