Kiwi is a small but nutrient-packed fruit that offers a surprising array of health benefits. Whether you’re a health-conscious eater, a fitness enthusiast, or just curious about what makes kiwi so special, this list covers key nutrition facts about one medium-sized kiwi. Understanding these facts can help you appreciate its role in a balanced diet.
Calories and Macronutrients
One medium kiwi, weighing about 70 grams, contains approximately 42 calories. It has a modest macronutrient profile with around 0.4 grams of fat, 0.8 grams of protein, and 10 grams of carbohydrates. This low-calorie count makes kiwi an excellent fruit choice for those looking to maintain or lose weight without sacrificing nutrition.
Rich Source of Vitamin C
Kiwi is famously rich in vitamin C, providing about 71 mg per medium fruit, which is more than the daily recommended intake for adults (65-90 mg). Vitamin C is crucial for immune function, skin health, and antioxidant protection. Eating one kiwi can help boost your immune defenses and support collagen production.
Dietary Fiber Content
One kiwi contains roughly 2.1 grams of dietary fiber, including both soluble and insoluble types. Fiber aids in digestion, helps regulate blood sugar, and promotes feelings of fullness. Including kiwi in your diet can contribute meaningfully to the recommended daily fiber intake of 25-30 grams.
Potassium Levels
Kiwi provides about 215 mg of potassium per medium fruit. Potassium is an essential mineral that helps regulate blood pressure, muscle contractions, and nerve signals. Incorporating kiwi can support cardiovascular health by helping maintain proper electrolyte balance.
Vitamin K Content
One kiwi offers approximately 40 micrograms of vitamin K, which accounts for about 33% of the daily recommended intake for adults. Vitamin K plays a vital role in blood clotting and bone metabolism. Regular consumption of kiwi can help support bone strength and reduce bleeding risks.
Antioxidants Beyond Vitamin C
Kiwi contains various antioxidants including lutein, zeaxanthin, and polyphenols. These compounds help combat oxidative stress and may protect against chronic diseases like heart disease and certain cancers. The presence of diverse antioxidants makes kiwi a powerful fruit for overall cellular health.
Low Glycemic Index
Kiwi has a low glycemic index of about 52, meaning it causes a slower and smaller rise in blood glucose levels compared to high-GI foods. This makes kiwi a suitable fruit option for people managing diabetes or anyone seeking to maintain stable energy levels.
Folate Content
With around 25 micrograms of folate per fruit, kiwi contributes to about 6% of the recommended daily intake. Folate is essential for DNA synthesis and repair, making it especially important for pregnant women to support fetal development. Including kiwi in your diet can help meet folate needs naturally.
Natural Sugars and Carbohydrates
Kiwi contains about 6 grams of natural sugars, primarily fructose and glucose, balanced by its fiber content. This natural sweetness satisfies cravings without the blood sugar spikes associated with processed sugars. The carbohydrate profile supports energy needs while being nutrient-dense.
Hydration and Water Content
Kiwi is approximately 83% water by weight, which helps with hydration and supports bodily functions like temperature regulation and joint lubrication. Eating kiwi can contribute to your daily fluid intake, especially in warmer climates or after exercise.
How to Choose
When selecting kiwi, the main factors to consider are ripeness and freshness rather than size or color. A ripe kiwi will yield slightly to gentle pressure but should not be mushy; this indicates optimal sweetness and texture. Avoid fruits with bruises, wrinkles, or overly soft spots, as these may be overripe or damaged. The skin color can vary from brown and fuzzy to smooth green (in varieties like golden kiwi), but taste is best judged by feel and aroma.
