Canning is a method of preserving food in air-tight vacuum-sealed containers and heat processing sufficiently to enable storing the food at normal-home temperatures. Canning is one of the safest ways to preserve foods. To retain peak quality, the shelf life of canned food is at least two years, and the vitamin level in canned food remains stable during the shelf life as long as the container is not damaged in any way.

Canning has no effect on proteins, carbohydrates and fats. If you take can meat, for example, it will have the same amount of protein and fat after canning as it had before. In general, canning does not seem to affect the nutritional values of food very much. From that point of view, you don’t have to feel sorry about turning to a can for a quick and convenient meal. Your fresh vegetables can lose more vitamins by lying in storage rack for a week. Canning is a useful way to preserve vitamins, as concentrations of some vitamins can decrease by 50% within the first 7 days after harvest when stored at ambient temperatures.

Canned food only needs to be warmed through before serving because it has already been cooked in the can. By keeping the cooking juices, canned foods lose remarkably little of their nutritional value. Canned poultry and fish, both protein foods, are comparable to their fresh-cooked counterparts in nutritional value. Protein is not lost during the canning process. And some varieties of canned fish tend to have higher calcium levels than their freshly cooked counterparts.

Many canned fruits and vegetables are high in vitamin A; canned products have comparable levels of vitamin A to their fresh or frozen counterparts. Canned food retains vitamin C for up to two years because the can is completely sealed and the food inside is cooked and stored in a vacuum. Canned pineapple, asparagus and grapefruits are significant sources of vitamin C.

There are an enormous variety of canned foods, which differ both in terms of type of ingredients and method of processing. In the end, it can be clearly stated that it’s better to go for canned food rather than bad food.

If you live in an area that freezes during the winter, here’s a tip for keeping your front steps from getting icy. Just take a bowl of hot water, add a few drops of Dawn dishwashing liquid to it. Once you’ve poured that mixture over the steps, they won’t freeze again. Sprinkling powdered laundry detergent on your roof can kill moss, but it won’t kill other things, even when the next rain leeches it down the downspout during the next summer shower. If you happen to see bubbling at the bottom of your downspouts, don’t panic. It’s just the detergent being washed off the roof, and it’s generally harmless to the environment.

If your children have decided to use the bedroom walls to create their latest crayon masterpieces, you’ll get excellent results by dipping a damp rag into baking soda and then using that mixture to scrub it off. It won’t be easy, but you can do it–assuming you’re willing to work at it–and it’s cheaper than repainting the room. Along those same lines, if your kids should use appliances or kitchen countertops as canvases for artwork instead of their bedroom walls, and their medium of choice is permanent marker, you’ll find that dipping a paper towel in rubbing alcohol will take it off. Like the walls, this mixture needs to be combined with a liberal dose of elbow grease.

Another commercial product that’s found in most people’s homes, WD-40, can serve double duty as a cleaner, as well. It can be used it to remove the pesky glue that’s so hard to get off when you peel labels or price tags off of plastic items. Just spray it on and rub it back off. It works like a charm, without harming the plastic itself. If you’re washing both the inside and outside, try using vertical strokes for one side of the window and horizontal ones for the other. That way, you’ll instantly be able to tell which side a streak is one. Instead of expensive window cleaners, you can use vinegar for outside windows. Using old sheets of newspaper also can minimize streaking. When you decide to tackle the window washing chore, do it on a cloudy day. You’ll experience less streaking and less frustration, because the windows won’t dry as quickly when the sun isn’t blazing down.
