Why are New Zealanders called kiwis

How healthy are kiwis?

There are very serious days among the celebrations, memorial days or days of action that deal with the promotion or maintenance of health. And there are those about which opinions can be as colorful as the blossoms on a bouquet of wild flowers. The “International Day of Jogging Pants”, the “Day of the German Apple” or, soon on May 24th, the “Eat a Kiwi Day” should feel at home in this class. There really is. Regardless of the fact that "Eat-a-Kiwi Day" was not proclaimed by the World Health Organization, but by New Zealand kiwi farmers in association with a German marketing agency, it is worth taking a closer look at the kiwi fruit.

Kiwis: good for smoothies, bad for yogurts

Kiwis are suitable for a balanced and varied diet, especially pure or as part of smoothies or fruit salad. However, nutrition experts advise against using it in combination with natural yoghurt. Kiwi fruits contain actinidine. This enzyme destroys the milk proteins contained in the yoghurt, the yoghurt tastes bitter. This can be prevented by briefly braising the fruit in the yoghurt just before consumption - or by opting for the sweeter, yellow kiwi variety. This contains less of this milk-decomposing enzyme.

Nine minerals, five vitamins

According to the New Zealand kiwi farmers and marketing company “Zespri”, 20 out of 50 nutrients that are important for humans are contained in kiwi fruits, including vitamins, minerals, antioxidants and trace elements. In an analysis by the German Research Institute for Food Chemistry, the following ingredients were determined:

Ingredients / nutrients:

  • Water: 83 grams
  • Protein: 1 gram
  • Carbohydrates: 9.1 grams
  • Dietary fiber: 2.1 grams
  • Minerals: 0.7 grams

Micronutrients:

  • nine minerals including potassium, calcium, magnesium, iron and zinc
  • five vitamins, including vitamin C3 and vitamins B1, 2 and 3.

One kiwi - the full daily dose of vitamin C.

One vitamin stands out in particular: vitamin C. Perhaps the best-known of the vitamins is considered helpful for defense against infection, for metabolism, bones and teeth, and as an antioxidant (protecting cells). During digestion, it improves the utilization of iron from plant-based foods and inhibits the formation of cancer-causing nitrosamines, according to a consumer information sheet from the German Nutrition Society (DGE).

For adults, the recommended daily dose is between 95 mg for women and 110 mg for men and. Pregnant women (105 mg) and breastfeeding women (125 mg per day) have a slightly higher vitamin C requirement; a significantly higher number of smokers (women: 135 mg, men: 155 mg). According to the DGE, the recommended natural sources of vitamin C include a glass of orange juice, a portion of (briefly) cooked broccoli or Brussels sprouts (150 g each), an apple or a kiwi fruit. They all provide around 150 mg of vitamin C at once - the full daily requirement of an average adult.

New Zealand Kiwis: Allegedly without chemical fertilizers

The question remains: How healthily are these "healthy" fruits grown? In the marketing talk of the marketing company "Zespri", the picture is painted of a "unique 12-step system", to which "in addition to the careful selection of the plantations" and " the protection of valuable resources ”also includes the“ renouncement of chemical fertilizers ”.

Conventional kiwi fruit: Low pesticide contamination - but frequent

In a study by the Lower Saxony State Office for Consumer Protection and Food Safety of kiwis from six countries of origin, on average only a third of conventionally grown kiwis were free of pesticide residues. When examining the kiwi samples, a total of seven different active ingredients were detected, the most common being the fungicide fenhexamid and the insecticide chlorpyrifos. However, the agency also found that in almost 90 percent of the samples only a Active ingredient pesticide has been registered. Conclusion of the state office: “The examined kiwi samples are only very slightly contaminated with pesticide residues. The maximum content was not exceeded in any of the samples. "

Kiwi - the fruit that is called like a round, brown bird

The fruit, initially known as "Chinese gooseberry", originally comes from northeast China. In the local forests it grows as a strong, woody liana or climbing shrub. The fruit came to Europe via a curious detour. A New Zealand teacher brought it home from a stay in China in 1904, where it became popular. Kiwi fruits grown in New Zealand have been exported to England since 1952, where they were also given the name “Kiwi”: after the bird that lives in the forests of New Zealand - which is also brown and spherical - but is called “the” kiwi.

Kiwis: only known in Germany since the 1970s

The kiwi fruit only became known in Germany in the early 1970s. The kiwi fruits offered in grocery stores today often come from New Zealand, but now also from several southern European countries. About half of the world's production comes from China. The second largest producer is Italy - ahead of New Zealand, Iran and Greece.
