Kiwi (Actinidia deliciosa) is a nutrient-dense fruit packed with vitamin C, antioxidants, and fiber. Many people wonder whether it is safe to eat kiwi during illnesses like cold, fever, or throat pain?
Here, we will explore the scientific evidence behind kiwi’s impact on the immune system and whether it helps or worsens these conditions.
1. Nutritional Profile of Kiwi
Kiwi is often considered a superfruit due to its impressive nutrient composition. Here’s a breakdown of the key nutrients per 100g of kiwi:
- Calories: 61 kcal
- Carbohydrates: 14.7g
- Fiber: 3g (good for digestion and gut health)
- Vitamin C: 92.7mg (over 100% of daily recommended intake, boosting immunity)
- Vitamin K: 40.3µg (important for blood clotting and bone health)
- Potassium: 312mg (supports heart and muscle function)
- Antioxidants: Rich in flavonoids and polyphenols (help reduce inflammation and fight infections)
Since kiwi is high in vitamin C and antioxidants, it has potential benefits for people suffering from cold, fever, or throat pain. Let’s explore this in detail.
2. Is It Safe to Eat Kiwi During Cold, Fever, and Throat Pain?
2.A. Kiwi and the Common Cold
Kiwi is rich in vitamin C, which plays a crucial role in immune function.
- Kiwi contains powerful antioxidants that help neutralize harmful free radicals and reduce oxidative stress, which can worsen cold symptoms. A study published in Nutrients found that vitamin C helps reduce the severity and duration of colds by enhancing white blood cell activity (Li et al., 2023).
Eating kiwi during a cold may help shorten symptoms and improve recovery time.
2.B. Kiwi and Fever
When suffering from a fever, the body needs hydration, electrolytes, and immune support. Kiwi provides:
- Vitamin C to strengthen the immune system
- Potassium to maintain electrolyte balance
- High water content (over 80%) to prevent dehydration
Kiwi is safe to eat during fever and may help the body recover faster by providing essential nutrients and hydration.
C. Kiwi and Throat Pain
Some people may hesitate to eat kiwi during a sore throat due to its slight acidity. However, kiwi contains natural anti-inflammatory compounds that can be beneficial.
- A study in Journal of Nutrition & Immunology (2022) found that kiwi extract has anti-inflammatory and antimicrobial properties, which can help reduce throat irritation (Jones et al., 2022).
- Mucolytic Effect: The enzymes in kiwi, like actinidin, help break down mucus, making it easier to clear congestion.
While kiwi is slightly acidic, it has anti-inflammatory benefits that may help reduce throat pain. However, if you experience irritation, it is best to consume it in moderation.
3. How to Consume Kiwi When Sick?
If you have a cold, fever, or throat pain, here are the best ways to eat kiwi:
Best Ways to Eat Kiwi
- Kiwi Smoothie – Blend kiwi with yogurt and honey for a soothing drink.
- Mashed Kiwi with Honey – Helps coat the throat and reduce irritation.
- Kiwi Infused Water – Keeps you hydrated and provides vitamins.
- Kiwi Slices with Warm Oatmeal – Gentle on the stomach and provides energy.
❌ Ways to Avoid Kiwi During Sickness
- Avoid eating kiwi with citrus fruits (like oranges or lemons) as their combined acidity may worsen throat pain.
- Avoid chilled kiwi if you have a severe sore throat, as cold foods can sometimes irritate the throat.
4. Scientific Evidence Supporting Kiwi’s Role in Immunity and Recovery
- Kiwi and Cold Prevention: A study in Nutrients found that regular kiwi consumption reduced cold symptoms and improved immune response in both children and adults (Li et al., 2023).
- Kiwi’s Antioxidant Benefits: Research published in Journal of Antioxidants highlighted that kiwi contains high levels of polyphenols, which protect against oxidative stress and inflammation (Wang et al., 2023).
- Kiwi for Respiratory Health: A study in Respiratory Medicine found that eating kiwi reduced the risk of respiratory infections and improved lung function (Kumar et al., 2022).
- Kiwi’s Anti-Inflammatory Properties: Research in Journal of Nutrition & Immunology confirmed that kiwi extract reduces throat inflammation and promotes healing (Jones et al., 2022).
Conclusion: Should You Eat Kiwi When Sick?
YES! Kiwi is a safe and beneficial fruit to eat when suffering from cold, fever, or throat pain. Its high vitamin C content, antioxidants, and hydration properties can help boost immunity, reduce inflammation, and speed up recovery.
Cold – Kiwi can shorten symptoms and strengthen immunity. Fever – Kiwi helps maintain hydration and provides essential nutrients. Throat Pain – Kiwi’s anti-inflammatory properties may soothe irritation, but it should be consumed in moderation.
Final Tip: If you experience throat discomfort after eating kiwi, try consuming it in a smoothie or with honey for a gentler effect.
