Kiwis Shine as Nutrient Powerhouses for Health Enthusiasts

Nutritionists are increasingly advocating for kiwis as a valuable addition to one’s diet, highlighting their numerous health benefits. These small, brown fruits, often overlooked in favor of more traditional options like apples and bananas, are rich in essential nutrients. With a growing presence on social media, particularly among wellness influencers, kiwis are gaining recognition for their positive impact on digestion and sleep quality.

Rich in Essential Nutrients

Kiwis are packed with an impressive array of nutrients. A medium-sized kiwi contains just over two grams of fibre while providing only 48 calories. The skin is particularly fibre-rich, which helps regulate digestion and manage blood sugar levels. According to Judy Simon, a clinical dietitian at the University of Washington Medical Center, “Fibre slows digestion, helping to prevent blood sugar spikes,” which can increase the risk of Type 2 diabetes over time.

In addition to fibre, kiwis are an excellent source of Vitamin C. Each fruit contains approximately 56 mg of this vital nutrient, surpassing the amounts found in a clementine or half a grapefruit. This amount represents 62 percent of the daily Vitamin C recommendation for men and 75 percent for women. Danielle Davis, a dietitian specializing in gut health at NYC Health + Hospitals/Bellevue, emphasizes the importance of Vitamin C, stating, “It supports your immune system and plays an important role in wound healing.”

Kiwis also boast around 150 mg of potassium, a mineral essential for maintaining healthy blood pressure. While a banana contains about 400 mg, kiwis still offer a substantial amount that helps counteract the effects of excess sodium. Furthermore, the presence of beneficial unsaturated fats in kiwis aids in the absorption of fat-soluble vitamins like Vitamins A and E.

Promoting Digestive Health

When it comes to digestive health, kiwis are particularly beneficial. Dr. Shanti Eswaran, a gastroenterologist at Michigan Medicine, often recommends kiwis as a natural remedy for constipation. “One kiwi provides more fibre than four prunes,” she notes, highlighting that many patients find kiwis more palatable. A recent study conducted in 2023 with around 200 participants found that those who consumed two green kiwis daily experienced an increase in bowel movements per week.

Kiwis contain both soluble and insoluble fibre, which together contribute to effective digestion. Soluble fibre forms a gel-like substance in the intestines, which helps soften stool and makes it easier to pass. Amy Ellis, an associate professor of nutrition at the University of Alabama, explains, “For healthy stool, you want it to be kind of fluffy.” Insoluble fibre adds bulk to stool, promoting regularity.

Additionally, kiwis are unique among fruits for containing an enzyme called actinidin, which may aid in protein digestion. While animal studies suggest potential benefits, further research is needed to determine its impact on human digestion.

Contemplating Sleep Benefits

Some wellness advocates claim that kiwis can enhance sleep quality, citing a small study from 2023 involving elite athletes. In this research, participants who consumed two kiwis one hour before bedtime for four weeks reported improved sleep quality. Kiwis have trace amounts of melatonin, a hormone associated with sleep regulation, and a small amount of serotonin, which is involved in melatonin production.

Despite these claims, Judy Simon cautions that there is insufficient evidence to support the notion that kiwis significantly affect sleep. “The studies just aren’t strong,” she states. Those who experience better sleep may simply be benefiting from healthier dietary choices, such as replacing sugary snacks with kiwis before bed.

Incorporating Kiwis into Your Diet

To enjoy the health benefits of kiwis, consider incorporating them into your meals. Blend kiwis into smoothies, add them to fruit salads, or top Greek yogurt with slices. For those adventurous enough, eating kiwis with the skin can provide additional fibre, although Danielle Davis suggests starting with yellow varieties, which are less fuzzy.

As nutritionists continue to highlight the advantages of this nutrient-dense fruit, kiwis are poised to find a permanent place on grocery lists across the world. Their combination of taste and health benefits makes them a worthwhile choice for anyone looking to enhance their diet.
