Sweet potatoes are a nightshade

Batata is the botanical name of the sweet potato. But the name and appearance are deceptive.

Sweet potatoes and table potatoes look similar, but are not botanically related. Both are originally from South America. The potato belongs to the nightshade family, the sweet potato is a bindweed family. It is exported from Brazil, Israel, the USA and China, but now also thrives in our latitudes and is ideally planted after the ice saints. The sweet potato is also available in gardening shops under the name Ipomea Batata.

At the end of April, when the soil temperatures are above ten degrees Celsius, it is advisable to place the plants in the beds with a row spacing of 50 to 60 centimeters. A mulch film can also provide the necessary ground warmth. Harvest time is in September. In summer you have to water sufficiently, possibly also a little fertilizer. Alternatively, it is worth trying to plant in a larger and deeper balcony tub. Due to their high water content, sweet potatoes can only be stored for a limited time. They don't like cold below five degrees and need a dark, dry place - neither a fridge nor a kitchen.

Both table potatoes and sweet potatoes contain important minerals such as potassium, zinc, calcium and many vitamins. The proportions of beta-carotene and vitamin A are higher in sweet potatoes. The potato, on the other hand, provides more folic acid and phosphorus. The sugar content and the so-called sweet potato or batata starch vary depending on the climatic conditions. Here's a comparison (200 grams each uncooked): Sweet potatoes contain ten grams of sugar, 215 calories, six grams of fiber and three grams of protein. Potatoes, on the other hand, contain two grams of sugar, 140 calories, four grams of fiber and four grams of protein.

Domestic potatoes even consist of 80 percent water and 15 percent starch - so, from that point of view, they are not fattening. The potato protein is characterized by a high content of the essential amino acid lysine for plant-based foods. The health value increases in combination with the protein from milk, egg or legumes.

Incidentally, eating the peel with potatoes is not advisable, even if this is a popular practice. The skin, eyes and germs contain solanine - by the way, sweet potatoes do not. The neurotoxin can cause nausea and headaches in sensitive people, sick people or children. Solanine protects the tuber from predators. Green areas also contain the substance. It is enough to remove these stains very generously. New potatoes should also be scrubbed well to remove most of the peel. The season in Germany is from the end of May to the beginning of June. The aroma is often not as intense as with fully ripe table potatoes. Their season starts in August.

A word about storage: if possible, do not store potatoes in the refrigerator. They like it dry, cool and dark. After all, it is nightshade family.
