What 2 foods can you live off of?

Like berries, most beans are highly nutritious. Black (turtle), red (kidney), pinto and soy top the lists of so-called superfoods by many nutritionists. This is probably the best source of calcium and iron on the island. Beans are also a versatile island food, since once dried they can be preserved for a long time.

And if you're alone on the island, why worry about flatulence? While most leafy greens will be good for you, kale is particularly rich in vitamins, minerals and fiber. You can boil the stalks to get a simple vegetable broth. Kale was obtained from wild cabbage and its close cousins include broccoli, Brussels sprouts, cauliflower, cabbage, collards, kohlrabi, kohlrabi, mustard and rapini. Like berries, cantaloupe is tasty and nutritious.

Although it's a little high in sugar, it's too good a source of vitamins A and C and potassium to pass up. Their lack of fat and lower glycemic load index make melons a slightly better choice than bananas. Choose if they are available for collection. Few foods match berries in flavor, vitamin content and antioxidant power.

Add to this list the kiwi, which was once called Chinese gooseberry, but which was changed for marketing reasons. Kiwis have more vitamin C than oranges and almost as much potassium as a banana. Watch out for poisonous berries, such as holly, frankberry, and bamboo berry. Even the laziest of us can harvest what is washed.

Seaweed, alaria and lavender (kombu, wakame and nori in Japanese cuisine) are among the most common. Algae are loaded with vitamins and minerals. Once dry, it will also last for months. Seaweed is a regular part of the Asian diet, and most Japanese households have four or five types available.

Even if you avoid sushi, you've eaten seaweed in ice cream. Irish moss (carrageenan) is a thickening agent. People have survived solely, or almost exclusively, on potatoes for centuries. For example, during the potato famine in Ireland, the impoverished part of Irish citizens lived on potatoes and, when available, on milk.

This could be because food lacks the nutrients it lacks, or because foods have an overabundance of nutrients because they cannot process them due to a lack of the necessary macronutrients or micronutrients.
