Calories in Red Kiwi: Nutritional facts for Red Kiwi Types

One hundred grams (3.5 oz) of raw red kiwi fruit contains 61 calories.

One kilogram (1,000 g or 35.3 oz) of raw red kiwi fruit contains 610 calories.

One standard medium red kiwi fruit weighing 75 g (2.6 oz) contains 46 calories. A large fruit weighing 95 g (3.4 oz) contains 58 calories. A small fruit weighing 60 g (2.1 oz) contains 37 calories.

Red kiwi provides some health benefits like boosting immune function and reducing oxidative stress due to its high concentration of Vitamin C and anthocyanins. This fruit, frequently called "Hongyang," "red-heart kiwi," or "rainbow kiwi," is a sweet, hairless variety of the kiwifruit family. A list of the health benefits of red kiwi is shown below.

• Boosts Immune System: A 100 g (3.5 oz) serving provides 93 mg of Vitamin C, fulfilling 103% of the Daily Value (DV). A study by Carr and Maggini (2017), "Vitamin C and Immune Function," confirms that high intake of Vitamin C supports various cellular functions of both the innate and adaptive immune systems.
• Reduces Oxidative Stress: Red kiwi contains anthocyanins, the pigments responsible for its red core, which are potent antioxidants. Research by Li et al. (2015), "Antioxidant activities of red-fleshed kiwifruit," demonstrated that red kiwi extracts effectively neutralize free radicals.
• Supports Digestive Health: The 3 g of dietary fiber per 100 g (3.5 oz) serving aids in regular bowel movements. Additionally, the enzyme actinidin helps break down proteins, facilitating digestion.
• Promotes Heart Health: The potassium content of 312 mg per 100 g (3.5 oz) helps regulate blood pressure, while fiber assists in lowering cholesterol levels.
• Enhances Skin Health: Vitamin C is essential for collagen synthesis, which maintains skin elasticity and wound healing.
• Regulates Blood Sugar: The low glycemic index and fiber content help moderate glucose absorption, preventing rapid insulin spikes.
• Supports Eye Health: The fruit contains lutein and zeaxanthin, which protect the retina from oxidative damage.

Red kiwi has been known to cause some unwanted effects like allergic reactions and digestive irritation due to its actinidin content and oxalates. A list of the downsides of red kiwi is shown below.

• Triggers Allergic Reactions: Individuals with latex allergies may experience cross-reactivity, known as "fruit-latex syndrome," leading to itching or swelling in the mouth.
• Digestive Irritation: The enzyme actinidin can cause mouth irritation or stomach upset in sensitive individuals if consumed in large quantities.
• Risk of Kidney Stones: Red kiwi contains oxalates, which can contribute to kidney stone formation in susceptible individuals.
• Interference with Blood Thinners: The Vitamin K content can interact with anticoagulant medications like warfarin if consumption fluctuates significantly.
• High Cost and Fragility: The fruit is more expensive and has a shorter shelf life than green kiwi, limiting accessibility.

Yes, red kiwis are good for you because they deliver 103% of the DV for Vitamin C and powerful antioxidants like anthocyanins in every 100 g (3.5 oz) serving. Healthy individuals should consume 150 g (5.3 oz) or roughly 2 medium fruits per day to gain immune and cardiovascular benefits. The major benefits include the reduction of oxidative stress and the support of digestive health through actinidin. It is an ideal nutrient-dense fruit for those seeking a sweet, berry-like alternative to traditional tart kiwis.

The calories in red kiwi do not vary significantly between fresh cultivars, as most varieties contain approximately 61 to 63 calories per 100 g (3.5 oz). The primary difference lies in the sugar concentration, with newer hybrids bred for intense sweetness containing marginally more natural fructose. Processed forms show the most significant variation; dried red kiwi slices contain approximately 340 calories per 100 g (3.5 oz) due to the removal of water which concentrates the natural sugars.

The origin of the red kiwi (Actinidia chinensis) is the Sichuan province of China, specifically the mountainous regions where wild kiwi varieties have grown for centuries. The specific "Hongyang" variety was discovered in the wild in 1986 by researchers from the Sichuan Provincial Academy of Natural Resource Sciences.

Unlike the green Hayward kiwi (Actinidia deliciosa) which was commercialized in New Zealand, the red kiwi is a distinct species noted for its hairless skin and sweet, berry-like flavor profile. Commercial cultivation began in China in the late 1990s and has since expanded to New Zealand and Italy under licensed propagation programs. Today, China remains the largest producer, but international exports are growing as global consumers seek sweeter, novel fruit varieties.
