List of Food to Avoid
When you have flu, it is imperative to know what foods to eat. However, it is just as imperative to know what foods to avoid. The last thing you’d want is to aggravate the condition by eating something you shouldn’t.
Here’s a list of foods you must avoid when you have flu:
Sugar leads to inflammation, which tends to weaken the white blood cells in your body. As white blood cells play a leading role in fighting infections, you must avoid sugar while fighting flu to ensure your body’s defense mechanism doesn’t get weakened.
2. Simple Carbohydrates
Looking for buttered toast, saltiness, or a bowl of pasta? We suggest you think again. Your body breaks down simple, refined carbohydrates into sugar, prompting the similar rise in blood sugar as caused by snacks and sugary drinks, and with similar inflammatory effects.
Similar to sugar, alcohol weakens your white blood cells and leads to inflammation. Also, it contributes to dehydration. Typically, staying hydrated is important when you’re ill since mucous membranes in the nose flush out viruses more effectively when they are damp. Therefore, dehydration will only worsen your symptoms.
4. Spicy food
If your flu symptoms include an upset stomach, refrain from the hot stuff since it will only worsen your symptoms.
5. Citrus Fruits
Citrus fruits, including lemon, grapefruit, and oranges, tend to irritate the lining of your stomach and intestines, hence aggravating the symptoms of an upset stomach. Also, in case you are feeling nauseatic while having flu, your best bet will be to refrain from all types of citrus fruits.
6. Fatty foods
Fatty, creamy, and greasy foods tend to cause inflammation, thereby weakening your immune system. Also, they are usually tougher to digest than protein or carbohydrates, so you’d do well by avoiding fatty foods when you have flu.
