What you should know about potatoes
In addition to important minerals and vitamins, the low-calorie potato also contains a complete amino acid profile as well as starch and carotenoids (plant pigments with an antioxidant effect).As a useful plant, the potato belongs to the nightshade family. Around 400,000 tons are harvested worldwide every year. The potato tubers develop in the soil just below the surface. The herbaceous, green potato plant with short-stemmed leaves can grow up to a meter high.
Seed-containing berries develop in the flowers. The green colored parts of the potato plant are poisonous. They contain alkaloids (nitrogenous, poisonous plant components). The edible tuber was brought to Europe by sea from South America in the 16th century. The first potatoes were shipped to mainland Europe from the Canary Islands. The first German potato cultivation is said to have taken place around 1650. A large number of potato varieties are now available on the market. The range includes more than 5500 different types of table potatoes. On the one hand, there are differences in maturity and quality groups.
The potato harvest takes place from late May to mid-October. The harvest season is divided into very early, early, medium early and medium late to very late. A distinction is also made between types of food and commercial types. An allocation is usually possible based on information on the tuber shape, skin and meat color. The name of the potato indicates the type of cooking: "waxy", "predominantly waxy" or "floury cooking". Waxy potatoes are particularly suitable for preparing dishes. The potato peel does not burst when cooked and the potato shows a firm structure and a smooth cut surface.
Potatoes can be boiled, deep-fried, fried, grilled, or steamed. They can be combined in many ways with dishes. Potatoes are valuable, healthy foods because of their high content of vitamins, minerals and trace elements as well as their high water content. The pleasant taste of the potato varies depending on how it is prepared. Since it does not have a dominant taste of its own, it can easily absorb other flavors of the food combination.
Importance to health
Potatoes have numerous valuable nutrients and the fiber they contain ensures a feeling of satiety for a long time. This reduces the feeling of hunger and, above all, the surprising ravenous hunger with its fatal effects.
The suitability of potatoes for a balanced diet is also illustrated by the high water content and the low fat content. The low-calorie nutrient supplier contains important minerals and vitamins as well as a complete amino acid profile as well as starch and carotenoids (plant pigments with antioxidant effects). This provides the body with energy reserves and the antioxidants can lower the risk of cancer. The high content of the special protective vitamin C in potatoes is also important for health. A serving of potatoes covers half of the daily requirement of vitamin C and the entire daily requirement of the mineral potassium.
The results of a Canadian research study indicated that potatoes noticeably improve memory performance. According to various test results, potatoes should also have antihypertensive ingredients. This is intended to act on the enzyme that is responsible for the production of a certain hormone. This hormone is supposed to constrict blood vessels in the long term and thereby increase blood pressure. Overall, the body's immune system is strengthened by the high nutrient content of the potatoes and the metabolism is regulated.
