Spinach in the context of "Chenopodioideae"

Quinoa (Chenopodium quinoa; /ˈkiːn.wɑː, kiˈnoʊ.ə/, from Quechua kinwa or kinuwa) is a flowering plant in the amaranth family. It is a herbaceous annual plant grown as a crop primarily for its edible seeds; the seeds are high in protein, dietary fiber, B vitamins and dietary minerals especially potassium and magnesium in amounts greater than in many grains. Quinoa is not a grass but rather a pseudocereal botanically related to spinach and amaranth (Amaranthus spp.), and originated in the Andean region of northwestern South America. It was first used to feed livestock 5,200–7,000 years ago, and for human consumption 3,000–4,000 years ago in the Lake Titicaca basin of Bolivia and Peru.

The plant thrives at high elevations and produces seeds that are rich in protein. Almost all production in the Andean region is done by small farms and associations. Its cultivation has spread to more than 70 countries, including Kenya, India, the United States, and European countries. As a result of increased consumption in North America, Europe, and Australasia, quinoa crop prices tripled between 2006 and 2014, entering a boom and bust cycle.

A salad is a dish consisting of mixed ingredients, frequently vegetables. They are typically served chilled or at room temperature, though some can be served warm. Condiments called salad dressings, which exist in a variety of flavors, are usually used to make a salad.

Garden salads have a base of raw leafy greens (sometimes young "baby" greens) such as lettuce, arugula (rocket), kale or spinach; they are common enough that the word salad alone often refers specifically to garden salads. Other types of salad include bean salad, tuna salad, bread salads (such as fattoush, panzanella), vegetable salads without leafy greens (such as Greek salad, potato salad, coleslaw), rice-, pasta- and noodle-based salads, fruit salads and dessert salads.

Leaf vegetables, also called leafy greens, vegetable greens, or simply greens, are plant leaves eaten as a vegetable, sometimes accompanied by their petioles and shoots, if tender. Leaf vegetables eaten raw in a salad can be called salad greens, whereas leaf vegetables eaten cooked can be called pot herbs.

Nearly one thousand species of plants with edible leaves are known. Leaf vegetables most often come from short-lived herbaceous plants, such as lettuce and spinach. Woody plants of various species also provide edible leaves.

Edible plant stems are a part of plants eaten by humans. Most plants are made up of stems, roots, leaves, flowers, and produce fruits containing seeds. Humans most commonly eat the seeds (e.g. maize, wheat), fruit (e.g. tomato, avocado, banana), flowers (e.g. broccoli), leaves (e.g. lettuce, spinach, and cabbage), roots (e.g. carrots, beets), and stems (e.g. asparagus of many plants. There are also a few edible petioles (also known as leaf stems) such as celery or rhubarb.

Plant stems have a variety of functions. Stems support the entire plant and have buds, leaves, flowers, and fruits. Stems are also a vital connection between leaves and roots. They conduct water and mineral nutrients through xylem tissue from roots upward, and organic compounds and some mineral nutrients through phloem tissue in any direction within the plant. Apical meristems, located at the shoot tip and axillary buds on the stem, allow plants to increase in length, surface, and mass. In some plants, such as cactus, stems are specialized for photosynthesis and water storage.

Low-carbohydrate diets restrict carbohydrate consumption relative to the average diet. Foods high in carbohydrates (e.g., sugar, bread, pasta) are limited, and replaced with foods containing a higher percentage of fat and protein (e.g., meat, poultry, fish, shellfish, eggs, cheese, nuts, and seeds), as well as low carbohydrate foods (e.g. spinach, kale, chard, collards, and other fibrous vegetables).

There is a lack of standardization of how much carbohydrate low-carbohydrate diets must have, and this has complicated research. One definition, from the American Academy of Family Physicians, specifies low-carbohydrate diets as having less than 20% of calories from carbohydrates.

Ullucus is a genus of flowering plants in the family Basellaceae, with one species, Ullucus tuberosus, a plant grown primarily as a root vegetable, secondarily as a leaf vegetable. The name ulluco is derived from the Quechua word ulluku, but depending on the region, it has many different names. These include illaco (in Aymara), melloco (in Ecuador), chungua or ruba (in Colombia), olluco or papa lisa (in Bolivia and Peru), or ulluma (in Argentina).

Ulluco is one of the most widely grown and economically important root crops in the Andean region of South America, second only to the potato. The tuber is the primary edible part, but the leaf is also used and is similar to spinach. They are known to contain high levels of protein, calcium, and carotene. Ulluco was used by the Incas prior to the arrival of Europeans in South America. The scrambling herbaceous plant grows up to 50 cm (20 in) high and forms starchy tubers below ground. These tubers are typically smooth and can be spherical or elongated. Generally they are a similar in size to the potato; however, they have been known to grow up to 15 cm (5.9 in) long. Due to the brightly coloured waxy skin in a variety of yellows, pinks and purples, ullucus tubers are regarded as one of the most striking foods in the Andean markets.

Caryophyllales (/ˌkæri.oʊfɪˈleɪliːz/ KARR-ee-oh-fih-LAY-leez) is a diverse and heterogeneous order of flowering plants with well-known members including cacti, carnations, beets, quinoa, spinach, amaranths, pigfaces and ice plants, oraches and saltbushes, goosefoots, sundews, Venus flytrap, tropical pitcher plants, Malabar spinach, bougainvilleas, four o'clock flowers, buckwheat, knotweeds, rhubarb, sorrels, purslanes, jojoba, and tamarisks. Many members are succulent, having fleshy stems or leaves.

The betalain pigments are unique in plants of this order and occur in all its core families with the exception of Caryophyllaceae and Molluginaceae. Noncore families, such as Nepenthaceae, instead produce anthocyanins. In its modern definition, the order encompasses a whole new group of families (formerly included in the order Polygonales) that never synthesize betalains, among which several families are carnivorous (like Nepenthaceae and Droseraceae).

Popeye the Sailor is an American animated series of short films based on the Popeye comic strip character created by E. C. Segar. In 1933, Max and Dave Fleischer's Fleischer Studios, based in New York City, adapted Segar's characters into a series of theatrical cartoon shorts for Paramount Pictures. The plotlines in the animated cartoons tended to be simpler than those presented in the comic strips, and the characters slightly different. A villain, usually Bluto, makes a move on Popeye's "sweetie", Olive Oyl. The villain clobbers Popeye until he eats spinach, giving him superhuman strength. Thus empowered, Popeye makes short work of the villain.

The Fleischer Popeye cartoons proved to be among the most popular of the 1930s, and would remain a staple of Paramount's release schedule for nearly 25 years. Paramount would take control of the studio in 1941 and rename it Famous Studios, ousting the Fleischer brothers and continuing production. The theatrical Popeye cartoons began airing on television in 1956, and the Popeye theatrical series was discontinued in 1957. Popeye the Sailor in all produced 231 short subjects that were broadcast on television for several years.
