The flu is a respiratory illness caused by influenza viruses. Five to 20 percent of the American population comes down with the flu each year, while 200,000 people find themselves in the hospital due to complications from the infection, according to the Centers for Disease Control and Prevention. Vaccinations are available each year to help protect you from flu, but if your immune system fails you, certain foods can help you get through a bout of the flu.
Try the BRAT Diet
The BRAT diet is an acronym for bananas, rice, applesauce and toast, all of which are good choices when you suffer from nausea, upset stomach and/or diarrhea. Joanne Larsen of AsktheDietitian states that these foods, along with beverages such as hot tea and apple juice, help control diarrhea. Both bananas and apples are sources of pectin, a soluble fiber which helps watery stools become more solid.
Replace Lost Body Fluids
Vomiting is one symptom that may accompany the flu, although it is more common in children than adults, according to FluFacts.com. To combat the vomiting, refrain from eating or drinking anything for at least one hour from the last incident. At this time, sip 2 ounces of water or some type of carbonated, lemon-lime beverage that is flat. If these stay down, try another 2 ounces of either beverage every 15 to 20 minutes. After a few hours, begin adding more beverages such as juice, hot tea, fruit juice or drinks, soup broth and jello. These will help replace lost body fluids without upsetting your stomach.
Stock up on Chicken Soup
Chicken soup is called nature's penicillin, according to ivillage.co.uk. It can help clear nasal congestion and is an easy way of getting the vegetables needed to boost your immunity. You can add bits of carrots, potatoes and squash. For an extra boost of healing power, add some cayenne pepper. The editors at Fitness magazine state that the capsaicin in the powder helps thin the mucus in your lungs and nasal passages.
Reach for the Ginger Root
Fresh ginger root, according to ivillage.co.uk, may help reduce both the fever and incessant coughing that often come with flu. To make your own ginger tea, simply grate two tablespoons of fresh ginger into a coffee filter and then pour one cup of boiling water over it. Let it steep for 10 minutes, then sip.
Try More Garlic
Garlic is an excellent decongestant and flu-fighting agent for a couple of different reasons. First, it contains alliin, which fights chest congestion. Second, it is a wonderful source of antioxidants, which help destroy the free radicals in your body that are damaging your cells.
