This Low-Cost Crop is a Well-Kept Health Food Secret which Helped Civilizations Grow in Europe and America
There is a well-kept secret in the nutrition and food industry. One of the lowest-cost food items is among the most nourishing and satisfying forms of carbohydrate. In this article, I share some little-known nutritional and historical facts about golden and red potatoes, which are among the healthiest carbohydrates when compared to most types of rice, pasta, bread. Potato’s impressive high fiber content and nutrient density (Vitamins A, B and C, micronutrients, magnesium, phosphate, potassium, iron, copper, and calcium) make it a superfood for our cardiovascular and digestive health as well as immune system. Because of its high fiber and micronutrient density, potato is a perfect food to satiate hunger while regulating blood sugar (although certain people should watch the glycemic index for white potato and certain other varieties, as explained below).
No wonder potatoes were among the earliest domesticated crops in the human history. Cultivation of potatoes in South America may go back 10,000 years. Over time, potato found its way to Europe and by the 19th century it was the most important new food in Europe because of its resistance to spoilage and its amazing nutrient density and value. Furthermore, boiled or baked potatoes were cheaper than rye bread, just as nutritious, and did not require a gristmill for grinding. Potato’s combination of nutrient density and low cost had a large effect on European demographics and society, due to the fact that it yielded about three times the calories per acre of grain while also being more nutritive and growing in a wider variety of soils and climates.
While in hotter climates of Portugal, Spain, Italy, and southern France the sweeter maize (corn which also yielded far more calories per acre than wheat) proved more popular, potato is believed to be a key in the economic development in central and northern Europe and England by underpinning the Industrial Revolution in the 19th century. Marxist Friedrich Engels even declared that the potato was the equal of iron for its "historically revolutionary role." In the German lands, Frederick the Great, king of Prussia (depicted in the drawing above), issued Kartoffelbefehl (potato order) in 1756, an official proclamation mandating potato cultivation. Frederick was later known as the Kartoffelkönig ("potato king").
Probably the first area of Europe to cultivate potato on a wide scale was Ireland in the early 17th century. As a result, by the 18th century the Irish population exploded, and its people subsisted almost entirely on the low-cost and prolific crop. The expansion of potato cultivation was due entirely to landless laborers, renting tiny plots from landowners who were interested only in raising cattle or producing grain for the market. A single acre of potatoes and the milk of a single cow was enough to feed a whole Irish family. Potato became a monotonous but nutritionally adequate diet for a poor yet healthy and vigorous rural population. Poor families even grew enough extra potatoes to feed a pig that they could sell for extra cash too.
Unfortunately, the Irish did not practice crop rotation, which caused depletion of the same farmed areas of soil from nutrients. Also, the Irish mainly cultivated (as a monocrop) the Lumper potato, a variety of white potato that yielded large crops in wet and low-nutrient garden soils but was poorly resistant to the potato blight (Phytophthora infestans known as HERB-1) which spread from America to Europe in the 1840s. As a result of the blight and plunging potato supply, the Irish Famine of 1845-1849 led to death of more than a million people and mass migration of another million (one the history’s largest mass migrations) from Ireland to the U.S. and Canada for the remainder of 19th century. By the mid 20th century, Ireland’s population stood at less than half of the pre-famine level of 8 million, while the populations of Canada and the US surged to historically high levels. So one can call potato (blight) a major factor in the economic and population expansion of North America in the late 19th century.
A freeze-dried form of potato popular with Andean people in South America (Peru and nearby countries) was chuño, which could be stored for years without refrigeration, which came into use, especially during years of famine or bad harvests. The Spanish fed chuño to the Inca silver miners who produced vast wealth in the 16th century for the Spanish government.
Golden (Yellow) Potato Compared to Red Potato
While both potatoes are an excellent source of vitamin C, the red potato is richer in anthocyanins (antioxidants) and the yellow potato in carotenoids.
If you're watching your carbs for blood sugar control, golden yellow potatoes may make a better choice than red potato. The boiled golden variety has a glycemic index of 58 as compared to 89 for a boiled red potato.
And of course, as stated in my article about pesticides, you want to eat potato which is not sprayed with chemicals or grown on damages soil so it’s best to always support small organic or chemical-free regenerative family farms, especially if you can directly buy from them.
