Kiwi: The Vitamin C Powerhouse
Kiwifruit, particularly the golden varieties, is a certified superstar when it comes to vitamin C content. A 100-gram serving of Zespri SunGold kiwi can contain over 160 mg of vitamin C, and even the standard green kiwi packs more than 80 mg per 100 grams. This means a single kiwi can often provide more than your entire recommended daily intake. Vitamin C is a powerful antioxidant essential for immune function, collagen production for healthy skin, and wound healing. Beyond its high vitamin C concentration, the humble kiwi also offers a wealth of other nutrients.
Other Nutritional Highlights of Kiwifruit
- Dietary Fiber: Kiwis are an excellent source of both soluble and insoluble fiber, which aids digestion, promotes gut health, and can help alleviate constipation. This unique fiber combination is rare among fruits and supports bowel regularity.
- Vitamin K: An often overlooked nutrient in fruits, kiwis are a good source of vitamin K, which is important for blood clotting and bone health.
- Antioxidants: Along with vitamin C, kiwis contain other antioxidants like lutein and zeaxanthin, which are beneficial for eye health and may help protect against age-related macular degeneration.
- Potassium: While not as famous for it as bananas, kiwis also contain a significant amount of potassium, which is important for managing blood pressure and heart health.
Bananas: The Potassium Champion
Bananas may not compete with kiwis in the vitamin C arena, but they have their own nutritional strengths. A medium-sized banana is well-known for its high potassium content, with one fruit providing around 422 mg, or about 9% of the daily value. Potassium is an essential electrolyte that helps regulate fluid balance, nerve signals, and muscle contractions.
Other Nutritional Benefits of Bananas
- Vitamin B6: Bananas are an excellent source of vitamin B6, which is crucial for metabolism, brain function, and immune health.
- Digestive Health: The fiber content, including resistant starch in unripe bananas, acts as a prebiotic, promoting the growth of beneficial gut bacteria and aiding digestion.
- Natural Energy: With a balance of natural sugars and fiber, bananas provide a sustained energy boost, making them a popular choice for pre- and post-workout fuel.
