Skip the lemon - 5 better fruits for a cough 😰
5 fruits to eat when you have a cough or cold - backed by research
When you are fighting a cough or cold, your immune system works overtime. While no fruit can cure a viral infection, certain fruits contain nutrients and bioactive compounds that may help reduce inflammation, support immune defenses, and ease respiratory discomfort.
Here are five fruits supported by nutrition research that may help during cold season.
1. Pomegranate 🍅
Pomegranate is rich in polyphenols, especially punicalagin, known for antiviral activity.
According to a
study published in PubMed, pomegranate polyphenol extract suppressed replication of influenza A virus in cultured cells and showed direct virucidal effects. Researchers identified punicalagin as a key compound involved in blocking viral RNA replication. These findings suggest pomegranate extracts may help reduce viral load during respiratory infections.
2. Kiwi
Kiwi is exceptionally high in vitamin C, a nutrient closely linked to immune function and respiratory health.
A study published in Antioxidants (MDPI) found that consuming two SunGold kiwifruit daily for six weeks restored adequate plasma vitamin C levels in adults with a history of severe respiratory infections. Researchers concluded that kiwi consumption can directly support antioxidant defenses during respiratory illness.
3. Tropical cherries 🍒
Instead of traditional lemon, consider tropical cherries such as Malpighia (acerola cherry) and Eugenia (Surinam cherry).
Acerola (
Malpighia glabra - Barbados Cherry) is one of the richest natural sources of vitamin C. Clinical research shows that adequate vitamin C intake is associated with reduced duration and severity of common cold symptoms. Vitamin C supports immune cell function and helps maintain the respiratory tract's protective barrier.
Eugenia species (Tropical Cherries) contain anthocyanins and phenolic compounds with antioxidant and anti-inflammatory properties, which may help reduce oxidative stress during illness.
4. Pineapple🍍
Pineapple contains bromelain, a group of proteolytic enzymes known for anti-inflammatory effects.
According to a
study published in PubMed, bromelain significantly reduced inflammatory cell infiltration in the lungs in a mouse model of airway inflammation. These findings suggest bromelain may help ease airway inflammation and congestion.
5. Berries and including mulberries
Strawberries, blueberries, raspberries, blackberries and mulberries are rich in flavonoids and vitamin C.
Although direct clinical trials on berries for colds are limited, nutrition reviews highlight their immunomodulatory potential. Flavonoids such as quercetin, anthocyanins, and catechins have demonstrated antioxidant effects and possible antiviral activity in laboratory studies.
Mulberries provide additional anthocyanins and resveratrol-like compounds, offering strong antioxidant support during illness.
