What fruits not to eat while sick?

3 min read

According to numerous health resources, while fruits are generally beneficial, some can aggravate symptoms like sore throats, congestion, and digestive issues due to their high acidity or sugar content. Knowing what fruits not to eat while sick can be just as important for a speedy recovery as knowing which ones to embrace.

Quick Summary

Certain fruits can worsen cold, flu, or stomach bug symptoms through their acidity or sugar content. It is best to avoid them for a more comfortable and faster recovery.

Key Points

  • Avoid Citrus Fruits: The high acidity in fruits like oranges and lemons can irritate a sore or inflamed throat, worsening coughs and discomfort.

  • Limit High-Sugar Fruits: Natural sugars found in fruits like bananas and grapes can thicken mucus and increase congestion, especially when you have a cold or cough.

  • Skip Raw and Unripe Fruits: When you have a stomach bug, the high fiber in raw fruits and the acidity in unripe varieties can worsen diarrhea and upset the stomach.

  • Consume Fruits at Room Temperature: Cold or chilled fruits can shock a sensitive throat and trigger coughing, making it more comfortable to eat them at room temperature.

  • Choose Gentle Alternatives: Soothing options like cooked apples, pears, and papaya are easier to digest and less likely to irritate your throat or digestive system during illness.

  • Consider Your Symptoms: While bananas are good for stomach upset (BRAT diet), they might increase mucus for those with respiratory issues, so be mindful of your specific ailment.

The Culprits: Fruits to Avoid While Sick

When your body is fighting off an illness, it becomes more sensitive. The wrong dietary choices can add unnecessary stress to your system, potentially prolonging your discomfort. Several types of fruits, despite being healthy under normal circumstances, should be put on hold until you feel better.

Citrus Fruits: A Sore Throat's Worst Enemy

While famous for their vitamin C content, which supports the immune system, citrus fruits like oranges, lemons, limes, and grapefruits can be highly problematic for a sore throat. Their high acidity can irritate and sting inflamed throat tissues, making coughing and swallowing more uncomfortable. This acidic nature can also trigger acid reflux, which further aggravates throat irritation.

High-Sugar Fruits: The Mucus Thickener

Some fruits, especially those high in natural sugars, can contribute to thicker mucus production and worsen congestion. This can be particularly true for bananas and grapes. When mucus thickens, it can feel like your chest is cloggier, making it harder to breathe and prolonging the duration of your cold symptoms. While natural, the influx of sugar can also be less beneficial than opting for more hydrating options when fighting an infection. Dried fruits are also a prime example of high-sugar options that should be avoided.

High-Fiber and Hard-to-Digest Fruits

If you are dealing with a stomach flu or any digestive upset, high-fiber or hard-to-digest fruits can be a bad choice. Raw fruits and vegetables, though generally healthy, can be difficult on an already sensitive gut and may worsen diarrhea. Unripe fruits, such as unripe mangoes or guava, are particularly hard to digest due to their high levels of citric acid, tannins, and starch, which can lead to bloating or discomfort. It is best to stick to bland, easy-to-digest options during these times.

Chilled or Frozen Fruits: Temperature Matters

Drinking a cold smoothie or eating chilled watermelon might seem refreshing, but when you have a sore throat or cough, the cold temperature can be irritating. Cold foods and drinks can cause throat discomfort and may trigger more coughing or strain on your respiratory system. For this reason, it's often recommended to consume foods and drinks at room temperature or warm when you're sick.

The Histamine Connection: Certain Berries and Kiwis

Some fruits contain histamine, a compound involved in allergic reactions, which could potentially worsen allergy-like symptoms during illness. While typically mild, some individuals with sensitivities may find that kiwis or certain berries, despite their antioxidant content, might exacerbate issues like congestion or a runny nose.

Comparison of Fruits During Sickness

Feature Fruits to Limit (When Sick) Better Choices (When Sick)
Acidity Citrus fruits (oranges, lemons), Pineapple, Unripe mangoes Pears (cooked), Cooked apples, Papaya
Sugar Content Grapes, Bananas, Dried fruits Strawberries (in moderation), Blueberries (in moderation), Avocado
Mucus Effect Bananas (can thicken mucus) Kiwi (supports immunity without acidity)
Digestibility Raw fruits, Unripe fruits, Dried fruits Applesauce, Bananas (for stomach issues, per BRAT diet)
Temperature Chilled watermelon, refrigerated fruits Room-temperature fruits, Warm cooked fruits

A Note on Bananas

It is important to address the differing advice on bananas. The BRAT diet, which includes bananas, is often recommended for individuals with upset stomachs and diarrhea because of the fruit's soluble fiber content. However, other sources caution that bananas can increase mucus production and worsen congestion for those with a cough or cold. This highlights the importance of listening to your own body and tailoring your fruit intake to your specific symptoms.

Conclusion: Mindful Eating for a Quicker Recovery

While the impulse to boost your immune system with a fruit-heavy diet when sick is understandable, it is essential to be mindful of which fruits you choose. Avoiding high-acidic, very cold, or high-sugar fruits can prevent the aggravation of symptoms like sore throats, congestion, and digestive issues. Instead, opt for gentle, room-temperature, and easily digestible alternatives like cooked apples, pears, or a modest amount of berries or kiwi. By listening to your body and making informed dietary choices, you can support your recovery and feel better sooner. For more comprehensive information on immune-boosting foods, consider consulting resources like the CDC.
