THE TRUTH ABOUT OLD WIVES TALES
I have read allot about nutrition over the years but the answer to this one surprised me, Compared to other dairy products, cottage cheese is actually a poor source of calcium. During the production, it loses 50 to 70 percent of the calcium initially present in the milk. Skim milk, non-fat milk and Swiss cheese contain much higher amounts of calcium. As for non-dairy sources, broccoli, spinach, salmon and sardines are high in calcium.
Ive heard this admonition all my life, but never had a explanation that made sense. After all, the inside of the can was sterilized before it was opened, so why not just cover the can and put it in the fridge? You save time and extra containers, which you dont sterilize, anyway. Unless the can got pushed to the back of the shelf and sat there for months, becoming a mold factory, Ive never had open canned food spoil. Still the warning had made enough of an impression so that I feel slightly uneasy whenever I ignore it.
To get to the bottom of whether or not this really is an OWT, They went to the top source, the U.S. Department of Agriculture. They confirmed my heretical belief that storing food in the original can in the fridge does not cause it to spoil faster. On the other hand, they did not recommend the practice. Why? Because the food is more likely to pick up an off-flavor from the can, even if its covered. They also reported that the Center for Science in the Public Interest offers another reason for transferring food to another container. The fact that if lead solder is used in the seams of the can the oxygen would help the lead dissolve and leach into the food, especially if its acidic like tomatoes or citrus juice.
