Raspberry (Rubus idaeus)
OriginThe berry from Mount Ida
According to legend, nymphs on Mount Ida gathered the first raspberries for baby Zeus – hence the name. Idaeus.
The raspberry grows wild throughout Europe and northern Asia, preferring forest edges, clearings, and open areas. Seed finds dating back to the Stone Age show that humans have been collecting them for millennia. In the Middle Ages, it was cultivated in monastery gardens, but selective breeding only began in the 16th century. Like the blackberry, it belongs to the genus *Raspberry*. Rubus; the fruit is an aggregate drupe made up of many small individual fruits that detach from the cone when picked - hence the hole in the middle.
Today, a distinction is made between summer raspberries, which bear fruit on the previous year's canes, and autumn raspberries, which fruit on the current year's canes until the first frost. Besides red varieties, there are yellow and black ones. Because raspberries are extremely delicate and prone to mold, they are one of the most expensive fruits commercially available – and one of the most rewarding to grow in your own garden.
To useWhat the raspberry does for you
The raspberry is a Fiber berryWith approximately 6.5 g of fiber per 100 g, it surpasses almost all other fruits, while containing only around 4 g of sugar and about 50 kcal. It also contains vitamin C, manganese, vitamin K, and plenty of polyphenols – especially… Ellagitannine, which are converted into urolithins by bacteria in the intestine, and anthocyanins.
Small controlled studies have found that raspberries eaten with a meal can reduce the rise in blood sugar and insulin levels in people with prediabetes. Ellagitannins and urolithins are the subject of intensive research, for example, in relation to inflammation and gut health – so far primarily in laboratory settings and small human studies.
An honest indication of Raspberry ketoneRaspberry flavoring is sold in capsule form as a weight-loss aid. The claims are based on animal studies with very high doses; there is no reliable evidence for its effectiveness in humans. Eating the whole fruit with its fiber is a better option.
IngredientsThis is what's inside the raspberry
Raspberries contain Dietary fiber (much of it in the small kernels), vitamin C (about 25 mg per 100 g), manganese, vitamin K, folate, and potassium. The red color comes from cyanidin glycosides. Characteristic are the Ellagitannine, especially sanguine H-6 and lambertianine C, as well as free ellagic acid.
The characteristic aroma is created by raspberry ketone together with ionones, which are also found in violets. A single raspberry contains very little raspberry ketone – dozens of kilograms of berries would be needed for a single capsule dose, which is why the capsule powder is usually produced synthetically.
