What is Kiwi?

What Is Kiwi

Kiwis, also known as kiwifruit, are a variety of fruits indigenous to the mountainous regions and hillsides of Southwest China. Today, they are cultivated in numerous other parts of the globe, including New Zealand, a leading producer of this widely consumed fruit. Additionally, kiwis are grown in various locations throughout the United States.

The introduction of kiwis to New Zealand can be attributed to Isabel Fraser, a schoolteacher who transported kiwi seeds back to her homeland after she traveled to China in 1904. Formerly known as Chinese gooseberry, the fruit was named “kiwi” by fruit exporters in New Zealand, inspired by the flightless kiwi birds unique to the country.

From a botanical standpoint, kiwis fall under the classification of berries. The two most commonly consumed species of Kiwi are Actinidia deliciosa and A. chinensis. The Hayward kiwi, a type of A. deliciosa kiwi, is famous.

What Is Kiwi 1

It is named after Hayward Wright, who was crucial in popularizing Kiwis in New Zealand during the 1920s. Hayward kiwis possess an oval shape similar to a large hen’s egg. They feature fuzzy brown skin, vibrant green flesh, and tiny black seeds.

In addition to the green-fleshed Hayward kiwis, yellow-fleshed or golden varieties exist (A. chinensis). The distinction between the two lies in the presence of chlorophyll, a green pigment found exclusively in green kiwis.

Notably, kiwi berries and kiwis belong to the same plant family, Actinidia. However, they are distinct species. Kiwi berries are small fruits with edible skin resembling grapes, while kiwis are larger in size and possess thicker, fuzzy skin.

What Is Kiwi 2

For most kiwi varieties, peeling off the skin before consumption is recommended. Yet, some individuals may prefer to consume the skin of golden or yellow Kiwi varieties as their skin is comparatively softer than green Kiwi.

In summary, kiwis are small fruits in green- and yellow-fleshed varieties. New Zealand serves as a prominent producer of kiwis, but these fruits are also cultivated in numerous other regions worldwide.

May Improve Digestive Health

One kiwi fruit contains more than two grams of dietary fiber. This fiber plays a crucial role in promoting a healthy digestive system. Researchers who have studied the fiber composition in kiwis have found that approximately one-third is soluble fiber, while the remaining two-thirds is insoluble fiber.

Soluble Fiber:

  • Possesses a viscous or gel-like consistency and can be fermented
  •  Dissolves when exposed to water
  •  Serves as a prebiotic, providing nourishment to beneficial bacteria in the gut

Insoluble Fiber:

  • Does not dissolve in water
  •  Cannot be fermented by gut bacteria
  •  Contributes to the formation of bulky stool, facilitating regular bowel movements
  •  It may help prevent constipation

It’s worth noting that individuals may exhibit varying sensitivities to dietary fiber. For those who suffer from irritable bowel syndrome (IBS), it may be necessary to exercise caution when consuming fiber-rich foods.

If you require further guidance on incorporating fibrous foods into your diet, it is advisable to seek advice from a qualified nutritionist or expert in the field.

Kiwifruit, carbohydrate availability, and the glycemic response

Kiwifruit Carbohydrate Availability And The Glycemic Response

A significant portion, approximately 10%, of the dry weight of kiwifruit is composed of primary cell walls. The available carbohydrates in kiwifruit account for about 80% of its dry matter and consist of glucose, fructose, and sucrose.

Additionally, around 10% of kiwifruit’s dry weight comprises digestible protein. The nonstarch polysaccharide nature of the cell wall component renders it indigestible in the stomach and small intestine.

Consequently, this component increases relative concentration within the gut lumen, where its physicochemical properties play a potentially important role in modulating carbohydrate digestion and absorption.

Upon release from the structural constraints of the fruit, the dietary fiber within kiwifruit swells to four times its original volume during in vitro digestion.

Kiwifruit Carbohydrate Availability And The Glycemic Response 1

Upon settling into a densely packed yet uncompressed state, as observed within the gut, the digested remnants of kiwifruit significantly reduce the rate of glucose diffusion by approximately 40%.

Moreover, they profoundly hinder digestion mixing, particularly when accompanied by a low background concentration of soluble viscous polysaccharides.

In vitro assessments of kiwifruit carbohydrates have provided estimations of their glycemic index (GI), which indicates a low value. In vivo estimates further support this finding.

Considering the high water content of kiwifruit, a 100g serving of this fruit affects blood glucose, equivalent to approximately 5g (or one teaspoon) of glucose. Therefore, kiwifruit have a low glycemic impact and are suitable for individuals with diabetes.
