Quinoa (from the Quechua kinua or kinuwa) is a pseudo-cereal belonging to the Chenopodioideae subfamily of the Amaranthaceae. It has been cultivated since ancient times in the Andes of what is currently known as Bolivia, Peru and Chile. Quinoa has a variable content of proteins of high biological value, which can range from 14 to 22% approximately. It is considered the only food of vegetable origin that provides all the essential amino acids, being its balance superior to that of wheat, barley and soybean. It is compared, as for its nutritional value, with the protein of the meat, eggs and milky, for what it can be of interest to introduce the quinoa in vegetarian diets or in those in which the contribution of essential amino acids is compromised. The absence of gluten makes quinoa a more than interesting option for celiacs. Its profile is predominantly unsaturated. Approximately half of quinoa's fats are composed of linoleic acid (known as Omega 6). It includes carbohydrates. Fiber is an important component of quinoa, its presence being higher in this food than in most cereals, but lower than in legumes. Therefore, the consumption of quinoa is another way to increase the contribution of fiber in the diet. It also has calcium, iron, potassium, magnesium and zinc, compared to many cereals, doubling and tripling the amounts present in wheat and rice, for example. As for vitamins, quinoa is a good source of vitamin E, riboflavin (B2) and folic acid (B9). Regarding the content of thiamine (B1), it is quite similar to that of cereals, and the content of niacin (B3) is lower than the latter. One of the most important aspects is the quantity and quality of the protein it contains, with 14.4 grams of protein in 100 grams of quinoa, it is very similar to that of eggs and milk, these are the best quality proteins among foods. It is worth mentioning that quinoa, being a vegetable food, can offer us a high value protein as the one of the animal origin food. It is also a cereal that provides energy thanks to the 72% of starches it contains. One hundred grams of cooked quinoa provides 86 calories. This favors people who perform jobs that demand physical effort, for athletes, pregnant women, older adults, children in growth stages, people with low weight or who have diseases whose defenses are low or that support a weight loss.
