While everyone is more concerned with microplastics, mercury, and lead in the foods we are supposed to eat, you should familiarize yourself with this list of items that you will not find in a pantry. But they are all things you can eat when you need to. Once the world collapses after the apocalypse, it is useful to know the things you can eat to (maybe) stay alive.
chalk . Although it is not toxic, it is still not advisable to eat large amounts of chalk. According to the US National Library of Medicine, real digestive problems can arise. However, an Instagram trend from 2018 in which ASMR accounts publish chalk-eating videos to get likes has not been stopped. If you crave chalk, chances are you have pica. This disease drives people to eat all kinds of non-food items like paper, sand and glue. ( Source )
Cigarettes . It is generally not recommended, especially not for children, since a single cigarette contains 20 mg of nicotine. Smokers only consume 1.5 mg per cigarette. But there are many survivors who suggest eating a cigarette as a natural parasite cleanser because the nicotine can kill intestinal parasites. ( Source )
dirt . More specifically, sound. People all over the world consume dirt from the depths of the soil under the topsoil. Initial studies suggest that it is consumed because of its protective properties against parasites, pathogens and plant toxins. Some places in the United States pack and sell white dirt called kaolin. It is often bought and consumed by pregnant women. ( Source )
Bark . Like all plants, some bark is toxic to humans. The inner bark (not the rough material on the outside of the tree) made of pine, black birch and balsam fir is filled with calories, starch, sugar, nutrients and (obviously) tons of fiber. It is still used all over the world, like in Sweden and Finland, where you can find bread made from pine bark flour. ( Source )
Leather . Leather products are now treated with highly toxic chemicals that make them inedible for humans. There is some record of Indians cooking leather for a few hours to make it edible, and the Thunder Party ate cooked leather before turning to cannibalism to survive. ( Source )
