Are potato tubers a sustainable source of protein?

The cultivation of potato tubers has a remarkably low carbon footprint, low water footprint, and low use of water compared to other protein crops, making them a sustainable source of plant proteins. Where most plant proteins are obtained from dry starch or oil seeds, potato proteins are extracted from juice obtained from the tuber.

What nutrients are found in potatoes?

Compounds existing in potatoes such as starch, protein, fiber, mineral, polyphenols, and carotenoids are thought to have a variety of benefits for human beings , although there are significant differences in the nutritional profiles and contributions of different potato cultivars to the human body.

Why is potato a stable food?

These authors contributed equally to this work. Potato (Solanum tuberosum L.) has gradually become a stable food worldwide since it can be a practical nutritional supplement and antioxidant as well as an energy provider for human beings. Financially and nutritionally, the cultivation and utility of potatoes is worthy of attention from the world.

What is the energy value of boiled potato?

Energy value of a boiled potato is lower (69 kcal energy per 100 g of weight) than a raw potato (80 kcal energy). Its low energy density in boiled form indicates that it is a good food for weight-conscious people. The energy value of potato is less than major food crops like rice, wheat, maize, and sorghum.

What elements are found in potatoes?

Potato can supply a part of daily requirements of trace elements such as manganese, copper, molybdenum, and chromium. Potato can also provide traces of boron, bromine, iodine, aluminum, cobalt, and selenium. A small potato can provide 10% DV of folate, magnesium, manganese, and phosphorus.
