There is actually no food item that you could survive on indefinitely on its own. There are 20 amino acids, 9 essential ones your body cannot produce by itself and many vitamins and minerals essential for proper brain and body function; not to mention your overall health.
"The only food that provides all the nutrients that humans need is human milk," Hattner said. "Mother's milk is a complete food. We may add some solid foods to an infant's diet in the first year of life to provide more iron and other nutrients, but there is a little bit of everything in human milk."
Eating only one food probably won't do any harm in the short term. However, there is no known food that supplies all the needs of human adults on a long-term basis.
A balanced diet of survival food will ensure that your body is getting all the protein, carbs, minerals, and vitamins it requires to remain healthy. If you could only select five foods to survive on, potatoes, kale, trail mix, grains, and beans would get you pretty far.
Can you survive with beans and rice? Yes you can if you know how to use your stock of beans and rice to their full potential. Beans and rice are packed full of energy, nutrition, vitamins and minerals. And they can be used in multiple ways beyond just plain “beans and rice.”
Although eggs are nutritious, the egg diet doesn't have enough variety or calories to be considered a healthy or sustainable way of eating. With such restriction, weight regain is likely. You'll also miss out on fiber, calcium, and other essential nutrients by sticking to the egg diet for more than a few days.
Without the vitamin, scurvy would bring on rashes and gum disease, not to mention very bad breath. Moreover, meat lacks fiber, so you'd probably be constipated. All in all, you wouldn't be healthy or comfortable. That said, some groups of people have survived—even thrived—on an animal-only diet.
A fruitarian diet is very restrictive, excluding a lot of food groups. It does not include the range of nutrients that the body needs for optimal health. A fruit diet is also high in sugar, which may lead to a number of health problems.
Professor Hoss-Cruz further explained, "the problem with potatoes is you'd get enough calories, but when you only eat one food source—especially one plant food source—you won't get all the protein you need." She said potatoes and milk would provide a complete set of protein, but a person would still run short on other ...
Corn. Historically, Ukraine has been one of the world's leading providers of corn, but that's all changed since Russia's invasion — which has no end in sight. ...
If you have the space, experts recommend a week's supply of food and water. Choose foods that don't require refrigeration and are not high in salt. Your stockpile should also contain flashlights, a manual can opener, a radio, batteries and copies of important documents.
Bottom Line. Living on $1,000 per month is a challenge. From the high costs of housing, transportation and food, plus trying to keep your bills to a minimum, it would be difficult for anyone living alone to make this work. But with some creativity, roommates and strategy, you might be able to pull it off.
