Star Fruit, as it is called in English-speaking countries like Kenya, is little known in Italy as Carambola, which comes from its plant, the Averrhoa Carambola. 
On the other hand, the name of the plant itself, originally from the Malay Peninsula and belonging to the Oxalidaceae family, derives from the shape of the fruit, which resembles a star. The ripe fruits are oval, light yellow in colour, with five pointed lobes arranged vertically along the surface.
Cutting the fruit widthwise, the shape of each slice is reminiscent of a five-pointed star.
Since the eighteenth century, it was imported into Europe to be displayed at the banquets of nobles and kings as a decoration.
Today, however, it is beginning to be appreciated for its incredible qualities. 
The carambola contains a very long list of essential nutrients, antioxidants and vitamins, but at the same time it is low in sugar (100 grams of pulp have only 31 calories).
The waxy skin provides a good amount of dietary fiber. The fiber helps prevent the absorption of LDL cholesterol. 
The fruit has digestive properties, it is very astringent when immature. You can recognize its ripeness by its colour, a definite yellow-orange.
Star Fruit has found use in traditional medicine for the treatment of certain pathological conditions, such as headache, nausea, cough, insomnia, hypertension and diabetes. 
As far as its therapeutic properties are concerned, starfruit is rich in vitamin C, which has antioxidant power and boosts the immune defences - potassium, which helps to rebalance the presence of liquids in the body and is an efficient aid to the cardiovascular system - and fibers that regulate the intestine.
It is possible to use the fruit also green, squeezed in dishes like a lemon or sliced in salads. The taste of the carambola is a mixture of different fruits, such as lemon, pineapple, plum.replique patek philippe
