Kiwi, also known as kiwifruit or Chinese gooseberry, is a nutrient-dense fruit celebrated for its vibrant flavor, high vitamin C content, and numerous health benefits. While primarily valued for its vitamins, minerals, and fiber, kiwi also contributes a small amount of protein to the diet. This article provides an in-depth analysis of the protein content in 100 grams, 200 grams, 500 grams, and 1 kilogram of kiwi, exploring variations based on preparation (fresh, dried) and variety (green, gold). A detailed table summarizes the protein content, and practical applications for incorporating kiwi into a balanced diet are discussed. External references from sources like USDA FoodData Central and Healthline provide data-backed insights.
Protein Content Across Different Quantities of Kiwi
Kiwi is primarily a carbohydrate-rich fruit with high water content (about 83%), making its protein contribution modest compared to protein-dense foods like legumes or meat. Below, we detail the protein content for the specified quantities, focusing on fresh kiwi fruit (edible flesh, peeled), as this is the most common form consumed. We also consider dried kiwi for comparison. Values are approximate, sourced from USDA FoodData Central, and reflect green kiwi unless stated otherwise, as it is the most widely consumed variety.
Protein in 100 Grams of Kiwi
The protein content in 100 grams of kiwi varies by preparation and variety:
-
Fresh Green Kiwi (raw, peeled): Approximately 1.14 grams of protein, 61 calories, 0.52 grams of fat, and 14.7 grams of carbohydrates. Green kiwi is tart, nutrient-dense, and low in protein but high in vitamin C.
-
Fresh Gold Kiwi (raw, peeled): Around 1.02 grams of protein, 63 calories, 0.56 grams of fat, and 15.8 grams of carbohydrates. Gold kiwi is sweeter and has a slightly lower protein content.
-
Dried Kiwi (unsweetened): Approximately 3.0 grams of protein, 275 calories, 1.5 grams of fat, and 66 grams of carbohydrates. Drying concentrates nutrients, including protein, due to water removal.
Kiwi’s protein is incomplete, lacking sufficient amounts of certain essential amino acids, so it should be paired with other protein sources for nutritional balance.
Factors Influencing Protein Content
-
Variety: Green kiwi (Actinidia deliciosa) has slightly higher protein than gold kiwi (Actinidia chinensis), though differences are minimal.
-
Preparation: Fresh kiwi retains its natural protein content, while drying increases protein density due to reduced water content. Sweetened dried kiwi may have diluted nutrients due to added sugars.
-
Edible Portion: Only the flesh is typically consumed; the skin is edible but less common, with slightly higher protein (~1.4 g/100 g with skin) and fiber.
-
Processing: Juicing may reduce protein slightly due to filtration, though data is limited.
Protein in 200 Grams of Kiwi
To calculate protein in 200 grams, multiply the per-100-gram values by 2:
-
Fresh Green Kiwi: ~2.28 grams of protein (1.14 g × 2), 122 calories, 1.04 grams of fat, 29.4 grams of carbohydrates.
-
Fresh Gold Kiwi: ~2.04 grams of protein (1.02 g × 2), 126 calories, 1.12 grams of fat, 31.6 grams of carbohydrates.
-
Dried Kiwi: ~6.0 grams of protein (3.0 g × 2), 550 calories, 3.0 grams of fat, 132 grams of carbohydrates.
A 200-gram serving of fresh kiwi (about 2–3 medium fruits, peeled) is a typical snack or breakfast portion, providing minimal protein but significant vitamin C (85 mg/100 g, ~140% of daily needs). Dried kiwi offers more protein but is calorie-dense, requiring moderation.
Practical Applications
A 200-gram portion of fresh kiwi is ideal for breakfast bowls, smoothies, or snacks, offering hydration and micronutrients. Pair with protein-rich foods like Greek yogurt or nuts to enhance nutritional balance. Dried kiwi can be used sparingly in trail mixes or as a sweet treat.
Protein in 500 Grams of Kiwi
For 500 grams, multiply the per-100-gram values by 5:
-
Fresh Green Kiwi: ~5.7 grams of protein (1.14 g × 5), 305 calories, 2.6 grams of fat, 73.5 grams of carbohydrates.
-
Fresh Gold Kiwi: ~5.1 grams of protein (1.02 g × 5), 315 calories, 2.8 grams of fat, 79.0 grams of carbohydrates.
-
Dried Kiwi: ~15.0 grams of protein (3.0 g × 5), 1,375 calories, 7.5 grams of fat, 330 grams of carbohydrates.
A 500-gram serving of fresh kiwi (about 6–7 medium fruits) is suitable for sharing or multiple servings, contributing negligible protein but high levels of fiber (3 g/100 g) and antioxidants. Dried kiwi in this quantity is impractical due to excessive calories and sugar.
Considerations for Large Portions
Consuming 500 grams of fresh kiwi is feasible across meals or snacks, providing hydration and digestive benefits from fiber and actinidin (a digestive enzyme). Large amounts of dried kiwi can lead to excessive sugar and calorie intake, so limit to small portions (e.g., 20–50 g).
Protein in 1 Kilogram of Kiwi
For 1 kilogram (1,000 grams), multiply the per-100-gram values by 10. For whole kiwis, edible flesh constitutes about 80–85% of total weight due to the skin, but we focus on peeled flesh as commonly consumed.
-
Fresh Green Kiwi: ~11.4 grams of protein (1.14 g × 10), 610 calories, 5.2 grams of fat, 147.0 grams of carbohydrates.
-
Fresh Gold Kiwi: ~10.2 grams of protein (1.02 g × 10), 630 calories, 5.6 grams of fat, 158.0 grams of carbohydrates.
-
Dried Kiwi: ~30.0 grams of protein (3.0 g × 10), 2,750 calories, 15.0 grams of fat, 660.0 grams of carbohydrates.
A 1-kg portion of fresh kiwi (about 12–14 medium fruits, peeled) is typically consumed over multiple servings or by a group. It provides minimal protein (about 20% of daily needs for a 70-kg person requiring 56 g) but is rich in vitamin C and fiber. Dried kiwi in this quantity is not realistic for dietary purposes due to high caloric content.
