That depends. If you want foods that last longer, and are cheaper buy foods with preservatives. If you want foods that are healthier( foods with preservatives are most likely going to have extra fat, sugar and salt ) and are natural in taste, ( Some artificially preserved foods have an artificial taste that isn't as satifying as the real thing ) buy foods without artificial preservatives. It depends. Generally, avoid anything with nitrates. Some of the preservatives have been shown to have no negative effects, but nitrates seem to cause problems.

Yes. The preservatives actually make the foods resistant to bacteria and other microscopic organisms that are harmful to humans. Simple ones, such as salt and vinegar, have been around for centuries and were valued highly for their properties to keep food around longer.

What are some breads without preservatives?

Any bread can be made without preservatives- it will need to be consumed or frozen within a few days, or it starts to grow mold. "Artisan" breads- made at a local bakery that sells them directly to consumers usually do not have preservatives. Check with the bakery. Even better- learn how to bake (it is really not hard- I do it) and make some bread of your own. That way you know exactly what you put in it- and nothing tastes as good as bread warm from the oven.


Why doesn't mold grow on bread in 3 weeks and why doesn't grow?

Mold grows on bread really fast When making and storing homade bread, it is best to freeze it if you will not be using it within one week. Refrigerating bread helps to keep it a day or two longer. My bread went bad after three days without refrigerating it. Also homemade bread does not have preservatives - I've kept store bought bread (contains preservatives) for a couple of weeks, out of the frig -and for as long as three weeks refrigerated.

Is a juice box biodegradable?

That depends on if anything was added to it - like preservatives, to keep it fresh in a bottle, but since most Lime juice came from the fruit that grows on trees it is biodegradable. If it is not really lime juice but a chemical flavor then that may take longer to break down. Almost everything is biodegradable given enough time.

It really depends. I mean if the cake is loaded with preservatives then it most likely will last a little longer than an all natural cheesecake. I actually have one now in my freezer that's been in there for about 2 or 3 months. See how long yours stays.
