The Potato
The
potato was first cultivated somewhere between the borders of Peru and Bolivia
approximately 8,000 years ago. It is the world’s most widely grown tuber crop
and the 4th largest food crop in terms of fresh produce after rice, wheat and
corn. Peru is essentially the birthplace of the potato and in the Andean region
there are still thousands of varieties of potatoes that grow wildly. Farmers
there still cultivate up to 50 varieties that are commercially available, some
with medicinal and therapeutic value.
From
the Andeans, potatoes were taken to Europe post the colonization of South and
Central America by Spanish traders and have increased in popularity ever since.
It is at present the most consumed tuber crop in Europe and has become an
essential clog in fulfilling the dietary needs of most Europeans.
Potatoes
were first introduced to Central Asia approximately 150 years ago and since
then potatoes have become an important food source. In 2011 a University of
Michigan study set the average consumption of potatoes in the region at 143 kg
annual per capita, one of the highest in the world.
In
2004 a study done by the International Potato Center revealed that iron
deficiency was rampant in many countries in Central Asia including Uzbekistan,
Kazakhstan, Kyrgyzstan and Tajikistan. The center undertook an extensive study
to find an effective solution to the problem and it discovered that certain
varieties of potatoes especially those grown in Uzbekistan namely the Picasso
and Kuroda have the highest iron and zinc content on a dry weight basis.
The
center identified Central Asia as a region that can potentially impact the
overall global nutritional status especially with regards to iron deficiency
anemia and recognized the role of the potato as a solution to the problem.
Chronic
malnutrition especially iron deficiency is a critical problem in some parts of
Central Asia affecting up to 60% of women aged between 15 to 49 years and
children under the age of 3 (Uzbekistan).
The
potato is a fast-growing plant and grows well not only in large farms but also on small plots of land. Its yield of calories per acre (about 9.2 million) is
higher than that of maize (7.5 million), rice (7.4 million), wheat (3 million)
and soybean (2.8 million). The world’s largest producer of potatoes is China,
followed by India, the Russian Federation, Ukraine, the United States, Germany,
Poland, Bangladesh, Netherlands, France, the United Kingdom, Malawi, Turkey,
Canada, Iran, Peru, Egypt, Brazil, Algeria and Pakistan.
A
bulk of the potatoes that are produced around the world today are cultivated as
secondary crops, on a small scale, utilizing poor sandy soil with relatively
low yields.
Growing
potatoes is not only an option for farmers but it is also an option for anyone
with a bit of land to spare. Soil fertility does not have much of an impact on
production because potatoes can grow, as farmers in Poland and Ukraine have
shown, in relatively poor soil. Both countries produce in excess of what’s
required and their production capacity is bolstered by utilizing less fertile
soil. Even if the potatoes are not suitable for human consumption they can
still be used as animal feed.
The
demand for potatoes has doubled over the last 15 years and this is mainly due
to the growing demand for frozen and dried potatoes, chips and snacks.
Consumption
of potatoes in developing countries has also increased from 9 kg per capita in
the early 1960s to over 14 kg today. Belarus has the highest consumption of
potatoes per capita.
The
potato is a nutrient-dense food. It provides good nutritional return for
calories. It has a high energy yield and it is rich in vitamin C content.
Typically, 100 gm of potatoes will contain about 17 mg of Vitamin C.
In
addition to that, potatoes also contain vitamins A, B and D. The potato is also
rich in potassium and it further contains calcium, iron and phosphorus. It is
about 17% starch and it is one of the best natural sources of starch.
The
United Nations officially declared 2008 as the International Year of the
Potato. It was done in order to increase awareness of the importance of the
potato as a food source in developing nations. It dubbed the potato “the hidden
treasure”. Promotions were carried out throughout the year to increase
awareness on the contributions the honest potato can make in alleviating global
hunger.
