This is the #2 survival food to grow after lambs quarters. One aspect that is better than lambs quarters is; it is more easily storable during winter. You could survive on cooked onions for a long time. In a survival situation, like most of our survival crops, I suggest eating it as a soup. Onion is grown in 175 countries, which is more than any other crop in the world. [1] Arguably onion were also the first crop ever cultivated, both in ancient history 5500 BC and also in American history [2].

They do contain a bit of protien; and a good source of carbs and sugars, no fat to speak of. They contain sulfur which I believe is an underappreciated nutrient and might help prevent muscle wasting on a low protien diet since most protiens like collagen and keratin contain sulfur [3]. Sulfur is also necessary to produce insulin to maintain healthy blood sugar [4]. They also contain lots of fiber [5] which keeps the gut healthy, which is the most critical thing to survive.

Cultivation

Here is info on cultivation [6]. Onion is also very resistant to pests and diseases and can grow in almost any soil type [7]. The only downside is you only get about 5,000,000 calories per acre [8] which is about half of rice or 1/3 of corn, but still enough to feed 5 people per acre of plant.[9] Potatoes and corn are pretty on par with eachother [10]. One very important aspect of onion as a survival food is that it is easy to grow either from seed or from propogating the bulbs which is the best of both worlds. [11]

Varieties

Yellow, red, and white onions are the most common types. Yellow and red contain quercetin, red also contains anthocyanin.[12]

Yellow onions

A good keeping and producing yellow onion is the southport yellow globe [13] and can be purchased here.

Medicine

Onions were used as a performance enhancing drug in the Olympic games in ancient Greece [14]. This was likely because they killed bacteria that caused myositis, or muscle weakness such as Brucella.
