To ease your mind from the rising tension between nuclear-capable countries and worries of a civil unrest, investing a decent amount of money for this underground survival shelter may serve as one of your best life-saving decisions. At a price of $200,000, you get a Radius Engineering Survival Shelter with fiberglass shells that outlasts steel shells and concrete shells. Apart from the extremely tough walls, Radius also build their bunkers with air purifiers with a UV-radiation sterilization system too.
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.
1.  20 pounds of Rice.  As boring as it may sound, rice is one of the backbones of every food storage plan.  It is filling, nutritious  and with the use of  varied seasonings and condiments, highly adaptable in a variety of tasty meals.  The choice of white, brown or a combination of the two is up to you.  White rice has a longer shelf life but brown rice has more nutritional benefits.  In my own household, I like to combine the two along with some Jasmine, Basmati and Calrose sticky rice.

Freeze-dried food is nothing new. As early as the 13th century, the ancient Quechua and Aymara people of Bolivia and Peru pioneered a form of the process by exposing potatoes to the freezing temperatures of the Andes overnight, then drying them in the sun. In 1937, Nestlé used industrial technology to create the world’s first freeze-dried coffee, and in the 60s and 70s, the US military shipped freeze-dried food rations to the troops in Vietnam.
