In a root, a stem, and a leaf... human food...

- Return to start;

We mentioned at the beginning of this speech that plants store food in:
A root, or in a stem, or in a leaf, or in a fruit, or
Seed.

We quickly came to examples of food being stored in a fruit or a seed, and we started with what is related to sowing with grains because they are the most dangerous to human life and the launch of civilization, then we brought legumes because they have the second place, then we brought walnuts in general because they contain the two elements of food, protein and fat.

What remains is what the plant stores in the fruits, and these are the fruits and they are a lot of things. Including oranges, apples, pears, peaches, apricots, plums, and so on. Anyone who looks into it will find that it does not contain any of the basic food sources, I mean protein and fat, that are worth mentioning, and that sugar and starches are the one fixed principle that it contains, and even this is due to the fact that there is a lot of water in the fruit.
The matter of this fruit is well known.

It remains to quickly mention examples of what plants store in terms of food:
In the root
And in a leg
And in paper
In order to complete the general picture on which it is stored
Plant food.

- Radishes, turnips, carrots, etc.;

These are examples of plants that store their food in their roots. The root was a good place for storage because it was in the depths of the earth, so the earth had protection. They are all plants as old as time.

We add beets to it, and their risk of producing sugar is great. We add to it the sweet potato, which was originally native to tropical America. Then it moved to the Old World and spread in all parts of it, but its danger remained where it was planted, so it did not become an object for trade.

- Potato or potatoes;

We distinguished between the potato (potato) and the sweet potato, because the sweet potato is a root that contains a store of food in the ground, but the non-sweet potato (potato) has ground stems known as tubers. You look at one of them and find in it sunken “eyes” from which buds emerge. The tuber is cut into pieces, each with an eye and buds. They are buried in the ground and begin to settle in it and grow a new plant.

Potato, its first home is America, and the Spaniards transported it to Europe in the Old World after 1580. Potato is one of the most important nutritional plants for humans.

Potatoes contain about 78 percent water, about 18 percent carbohydrates (starches and the like), 2 percent protein, and 0.1 percent fat. Protein is one-ninth of its starch, and this has its dangers.

Europe grows 90 percent of the world's potato crop. It competes with wheat somewhat, as whole wheat flour contains about 73.5 percent of starches and about 9.5 percent of protein, meaning that the ratio of protein to starch in it is slightly more than one-eighth, while it is about one-ninth in potatoes. They resembled each other.

(The upper parts of sweet potatoes are moist, and the lower parts are dry, and the plant has true roots)

- Lettuce, cabbage, spinach, etc.;

Then to examples of plants that store food in their leaves, as well as in their stems, as in lettuce and cabbage.
Asparagus stores its food in its stem.

This stored food contains a lot of water and little starch. It contains some protein, especially in the leaves, which are the factory of the plant in which materials are made.

All vegetables, most of which are green leaves, even though they have lost the nutritional value to the extent that we are accustomed to, contain many of the salts that the body needs, and vitamins. For this reason, it was essential in food.

Then, after digestion, it leaves in the digestive canal residues of food that are not digested, such as cellulose residues, which have a roughness that helps move the food in the digestive canal.
