Mr. Patrick, who lives in the East Midlands region of England, says that people need not stock large quantities of food, and that his family has enough for only a week. “This is a case of having some candles as well as a torch, a battery-powered radio, perhaps a solar-powered phone charger,” he said, rejecting any parallel to doomsday preppers who prepare to barricade themselves in remote places with enough supplies for months or years.
Keep in mind is that temperature fluctuations can be as bad as a sustained high temperature.  I don’t claim to know the science but what I have found is that food stored at a constant 80 degrees will hold better than food stored at 30 in the winter and 90 in the summer.  Anecdotally, this is especially true of canned goods I have stored in my home.

A lot of electric mountain bikes have hit the market lately. I’ve listed one instead of a regular mountain bike because they can help you travel substantially faster than you would be able to without the extra boost. Of course it’s important to get a bike that will continue to work well even after you run out of electricity, in case you only want to use the boost initially, but not waste your precious post-SHTF electricity on bike speed later, which is why the ability to remove the battery off an electric bike completely is very helpful. No one needs to carry dead weight.
Fires happen at the best of times—when the SHTF, they are even more likely to happen. You need to be prepared. And you will be with the Firemask as part of your prepper gear This is a respiratory device that will protect against smoke inhalation, fire, and radiant heat. It also protects against carbon monoxide, ammonia, hydrogen sulfide, and other toxic gases.
Since people began building fallout shelters during the Cold War, canned nonperishable food has been recognized as great to have around when the going gets tough. Freeze-dried food and MRE (Meal, Ready-to-Eat) military rations with years of shelf life are also good options that take up less space per available calorie. [Doomsday Facts (and Fictions)]
