Fruits To Avoid During Fever

Fever is a condition that can affect individuals of all ages. It is typically characterized by an elevated body temperature, often accompanied by sweating, chills, headache, and body aches. The condition is usually a sign of an underlying infection or illness, with the body’s temperature rising as a natural defense mechanism against pathogens. The fever itself isn’t a disease but a symptom indicating the body’s efforts to fend off illness. Proper nutrition during a fever is crucial to support the immune system and aid recovery. While fruits are generally considered healthy, certain types may exacerbate fever symptoms due to their specific properties.

Fruits to Avoid During Fever

Citrus Fruits

Examples: oranges, lemons, limes

Citrus fruits are commonly recommended for their high vitamin C content, which is known to boost immunity. However, during a fever, the high acidity of citrus fruits can become problematic. These fruits have the potential to irritate the already inflamed mucous membranes, particularly if the fever is accompanied by a sore throat. The acidic juices can cause further discomfort, potentially worsening the sore throat. Additionally, the acidity might lead to stomach upset in some individuals, which can be detrimental when the body is already under stress.


Bananas are a staple fruit known for their high potassium content, which is beneficial for muscle function. However, during a fever, bananas can slow down digestion due to their high starch content. This can lead to a feeling of fullness and bloating, which can be uncomfortable when the body is fighting an illness. In certain individuals, bananas are known to increase mucus production, which can exacerbate symptoms of congestion that often accompany a fever.

Dried Fruits

Examples: raisins, dates, dried apricots

Dried fruits are a concentrated source of natural sugars, which can be both a boon and a bane for someone with a fever. While the natural sugars can provide quick energy, the high sugar content can suppress the immune system, potentially prolonging the illness. Additionally, dried fruits contain minimal water content, which can contribute to dehydration—an undesirable condition when one is already losing fluids through sweat due to fever.

Avocados Avocados are well-known for their healthy fats and are usually considered a nutritious addition to a balanced diet. However, their high-fat content makes them difficult to digest, which can be a concern when one’s digestive system is compromised during a fever. The richness of avocados can lead to bloating and discomfort, adding to the discomfort already caused by the fever.

Grapes Grapes are a delicious and hydrating fruit that many enjoy. However, they are rich in natural sugars, which can cause blood sugar levels to spike, potentially leading to energy crashes that can further weaken the body. For individuals who experience diarrhea as a symptom alongside fever, grapes can worsen the condition due to their laxative effects.

Additional Considerations

Processed Fruit Juices

Processed fruit juices are a common recommendation for hydration during illness, but they can contain significant amounts of added sugars. These sugars can weaken the immune system, making it harder for the body to fight off infections. Moreover, processed juices often lack the fiber found in whole fruits, leading to fluctuations in blood sugar levels that can affect energy levels and overall health.

Unripe Fruits

Examples: green bananas, unripe mangoes

Unripe fruits can be difficult to digest due to their high starch content and the presence of complex carbohydrates that require more energy to break down. This can lead to bloating, stomach pain, and discomfort, which are undesirable when the body is already under the stress of a fever. These fruits can also cause constipation, further complicating the body’s ability to recover efficiently.


In conclusion, while fruits are generally a healthy part of a balanced diet, certain fruits can be detrimental during a fever due to their specific properties. Citrus fruits, bananas, dried fruits, avocados, and grapes can exacerbate symptoms and hinder recovery in different ways. Additionally, processed fruit juices and unripe fruits pose their own set of challenges that can further strain the body’s immune system. It’s crucial to consult healthcare professionals for personalized advice, as each person’s needs may vary. Ultimately, balanced nutrition that supports the immune system is essential for aiding recovery during a fever.
