Foods to Help You Recover from the Flu


Ginger has been used for centuries in traditional medicine to treat a variety of ailments, including the common cold and flu. This root contains powerful compounds called gingerols, which have antibacterial properties that can help fight off infections.

In addition to its antibacterial effects, ginger is also known for its potent anti-inflammatory properties. Inflammation is a natural immune response that helps the body fight infection, but when it becomes chronic, it can lead to a host of health problems. Gingerols have been shown to inhibit the production of pro-inflammatory cytokines, helping to reduce inflammation in the body.

Research has shown that ginger can be particularly effective in reducing symptoms of respiratory infections like the flu. A study published in the Journal of Ethnopharmacology found that ginger extract was able to inhibit the replication of several strains of the influenza virus. Another study published in the International Journal of Preventive Medicine showed that ginger supplementation reduced the severity of flu-like symptoms in patients.

To take advantage of ginger’s medicinal properties, try adding fresh ginger to your diet. Grate it into hot water for a soothing tea, or add it to stir-fries, smoothies, and other dishes. You can also find ginger supplements in capsule form at health food stores.

Overall, ginger is a powerful natural remedy that can help support your immune system and reduce inflammation. Incorporating this flavorful root into your diet can help you recover more quickly from the flu and other illnesses.


Garlic: The Secret Weapon Against the Flu

Garlic has been hailed as a superfood for centuries, and for good reason. Not only does it add flavor to a variety of dishes, but it also has impressive medicinal properties that can help ward off illness, including the flu.

One of the key compounds in garlic is allicin, which has powerful antiviral and antibacterial effects. Allicin works by attacking the cell walls of harmful microbes, preventing them from reproducing and spreading throughout the body.

In addition to its antiviral and antibacterial properties, garlic is also rich in antioxidants, which help protect the body from oxidative stress and inflammation. This is important because inflammation can weaken the immune system, making it more susceptible to infection.

Research has shown that consuming garlic regularly can reduce the risk of getting sick, as well as the duration and severity of symptoms when you do get sick. For example, a study published in the journal Clinical Nutrition found that taking a garlic supplement for 12 weeks reduced the number of colds experienced by participants by over 60%.

To reap the benefits of garlic, it is best to consume it raw or lightly cooked. You can add it to soups, stews, stir-fries, or even eat it straight with some honey to mask the pungent taste.

Overall, garlic is a simple yet powerful way to support your immune system and fight off the flu. So next time you’re feeling under the weather, consider adding some extra garlic to your meals.

Chicken Soup

Chicken Soup

When you’re feeling under the weather, a warm bowl of chicken soup can be just what the doctor ordered. This classic comfort food has been a go-to remedy for generations, and for good reason. Not only is it soothing and easy to digest, but it also provides a range of benefits that can help support your recovery from the flu.

One key advantage of chicken soup when you have the flu is its ability to keep you hydrated. When you have a fever or are experiencing other flu symptoms, your body loses fluids more quickly than usual. Drinking plenty of water is essential, but you can also get fluids from foods like soup. The broth in chicken soup contains electrolytes like sodium and potassium, which can help replace those lost through sweating and other bodily functions.

In addition to hydration, chicken soup also has anti-inflammatory properties that can ease symptoms like congestion and sore throat. Research has shown that consuming chicken soup can reduce inflammation in the body, potentially helping to relieve the discomfort caused by flu-related inflammation.

But not all chicken soups are created equal. To get the maximum benefits, look for a soup made with high-quality broth and plenty of vegetables. Avoid soups that are high in sodium or contain additives like MSG. You can also add ingredients like ginger and garlic for an extra boost of immune-boosting and anti-inflammatory benefits.

In summary, chicken soup is more than just a comforting food when you have the flu. It’s a nutritious and hydrating option that can help ease symptoms and support your recovery. So next time you’re feeling unwell, consider whipping up a batch of homemade chicken soup or picking up a high-quality store-bought version.

Hot Tea

Hot Tea is a popular beverage that can be enjoyed any time of year, but it can be especially beneficial when you have the flu. Here are some reasons why:


Staying hydrated is important when you have the flu, as it helps to loosen mucus and reduce congestion. Hot tea can be a great way to hydrate because it’s mostly water, and it’s easier to drink than plain water when you don’t feel well. Additionally, adding lemon or honey to your tea can provide extra hydration and boost your immune system.


Tea is rich in antioxidants, which can help to protect your body from free radicals and support your immune system. These plant-based compounds can also help to reduce inflammation in the body, which is beneficial when you’re fighting off an infection. Some teas that are particularly high in antioxidants include green tea, black tea, and oolong tea.


Drinking hot tea can provide warmth and comfort when you’re feeling under the weather. The steam from the tea can also help to clear out your sinuses and ease congestion. Additionally, the act of drinking tea can be soothing and relaxing, which can help to reduce stress and promote better sleep.

Overall, hot tea is a great choice when you have the flu. It can provide hydration, antioxidants, and warmth, all of which can help to support your body’s natural healing process. Just be sure to choose caffeine-free options if you’re sensitive to stimulants or trying to get more rest.

Foods to Avoid When You Have the Flu

Processed Foods

Processed Foods

When you’re feeling under the weather, it can be tempting to reach for processed foods for a quick and easy meal. However, these convenience foods are often packed with preservatives and additives that can do more harm than good.

Preservatives are added to processed foods to extend their shelf life and prevent spoilage. While this may sound like a good thing, many preservatives have been linked to health problems such as allergies, asthma, and cancer. Some examples of common preservatives include nitrites (used in cured meats), BHA and BHT (found in packaged snacks), and sodium benzoate (used in soft drinks).

Additives are another common ingredient in processed foods. These are substances that are added to improve the taste, texture, or appearance of food, or to make it last longer. Unfortunately, many additives have also been linked to health problems. For example, artificial sweeteners like aspartame have been linked to headaches and other neurological symptoms, while food dyes like Red 40 have been linked to hyperactivity in children.

One of the biggest problems with processed foods is that they often lack important nutrients that your body needs to stay healthy. This is because many of the nutrients are lost during processing, or are simply not present in the first place. For example, whole grains are stripped of their fiber and nutrients when they are refined into white flour, while fruits and vegetables lose some of their vitamins and minerals when they are canned or frozen.

To stay healthy when you’re sick, it’s best to avoid processed foods as much as possible. Instead, focus on whole, nutrient-dense foods like fresh fruits and vegetables, whole grains, and lean protein sources. This will give your body the nutrients it needs to fight off infection and get back to full health.



Sugar is one of the most commonly consumed ingredients in the Western diet, but it is also one of the worst foods to eat when you have the flu. Consuming large amounts of sugar can compromise your immune system, leading to a longer and more severe illness.

Studies have shown that consuming sugar has an immunocompromising effect on the body, which can make it easier for viruses and bacteria to take hold. This is because sugar suppresses the activity of white blood cells, which are crucial for fighting off infections. When your body’s defenses are down, it is much harder to fight off the flu and other illnesses.

In addition to its immunocompromising effects, sugar also causes inflammation in the body. Inflammation can lead to a range of health problems, from chronic diseases like diabetes and heart disease to acute symptoms like joint pain and headaches. When you have the flu, your body is already under stress, so adding inflammation to the mix can make your symptoms worse.

Lastly, sugar feeds bad bacteria in the gut, which can further weaken your immune system. The gut is home to trillions of microorganisms, both good and bad, that play a vital role in our overall health. When bad bacteria outnumber the good, it can lead to digestive issues, decreased immunity, and other health problems.

To avoid these negative effects, it is best to limit your sugar intake as much as possible when you have the flu. This means avoiding processed foods and sugary drinks, and instead opting for whole foods like fresh fruits and vegetables, lean proteins, and healthy fats. By supporting your body with nutrient-dense foods, you can give your immune system the boost it needs to fight off the flu and recover quickly.


Alcohol is a common beverage that many people consume on a regular basis. However, when you have the flu, consuming alcohol can have negative effects on your body. In fact, it’s one of the worst things you can drink when you’re sick.

One of the main reasons why alcohol is not recommended when you’re sick is because it can cause dehydration. Dehydration is already a common symptom of the flu, and drinking alcohol can make it worse. Alcohol is a diuretic, meaning it causes you to urinate more frequently. This can lead to significant fluid loss, making it harder for your body to fight off the virus.

Another reason why alcohol is not good when you have the flu is because it can suppress your immune system. Your immune system is what fights off viruses and infections, and when it’s suppressed, it can’t do its job effectively. This means that your body will have a harder time fighting off the flu, and you may end up staying sick for longer than you would have otherwise.

Finally, consuming alcohol when you have the flu can also cause liver damage. Your liver is responsible for filtering toxins out of your body, and alcohol is a toxin. When your liver is working overtime trying to process alcohol, it can become damaged or inflamed. This can lead to long-term liver damage if it happens repeatedly over time.

In summary, alcohol should be avoided when you have the flu. It can cause dehydration, immune suppression, and liver damage, all of which can make your flu symptoms worse. Instead, focus on drinking plenty of water and other fluids that can help keep you hydrated, like electrolyte-rich sports drinks or homemade broth.



Caffeine is a common ingredient in many beverages, including coffee and tea. While it can provide a quick energy boost, it’s best to avoid caffeine when you have the flu. Here’s why:


One of the most significant effects of caffeine is dehydration. When you’re already struggling with replenishing fluids lost due to sweating and fever, adding caffeine to your diet only worsens the situation. It can lead to further dehydration, making it harder for your body to fight off the flu virus.

Interferes with Sleep

Getting plenty of rest is crucial when you have the flu. Unfortunately, caffeine can interfere with sleep, making it harder to get the rest you need. Lack of quality sleep can weaken your immune system and prolong your recovery time.


Caffeine can also lead to jitters or shaky hands, which can be uncomfortable when you’re already feeling unwell. Certain medications you may be taking for the flu, such as antihistamines, can also increase the likelihood of jitteriness if combined with caffeine.

In conclusion, while caffeine may provide an initial pick-me-up, it’s best to avoid it when you’re dealing with the flu. Instead, opt for hydrating drinks like water and herbal teas to support your body’s recovery.

Other Tips for Eating with the Flu



When you have the flu, staying hydrated is critical to your recovery process. Dehydration can exacerbate symptoms and prolong the duration of your illness.


Drinking water is the most effective way to stay hydrated while you are sick. It helps to flush out toxins from your body and keeps your mucous membranes moist, which can help with congestion. Aim to drink at least eight glasses of water a day, and more if you are experiencing vomiting or diarrhea.

Sports Drinks

Sports drinks like Gatorade or Powerade can also be effective in replenishing electrolytes that may be lost due to dehydration. These drinks contain sugars and salts that can help maintain hydration levels and provide energy for your body. However, it’s important to choose a sports drink that is low in sugar, as high sugar content can cause inflammation in your body and compromise your immune system.


Broth, such as chicken or vegetable broth, can also help keep you hydrated while providing essential nutrients to support your immune system. The warm liquid can soothe a sore throat and clear up congestion. Additionally, the sodium in broth can help your body absorb fluid more effectively and restore electrolyte balance.

In conclusion, when you have the flu, staying hydrated is crucial for a speedy recovery. Drinking water, sports drinks, and broth are all excellent options to help you stay hydrated and support your immune system. Remember to drink plenty of fluids throughout the day to keep your body hydrated and functioning properly.

Small Frequent Meals

Small Frequent Meals

When you’re feeling under the weather with the flu, eating large meals can be overwhelming. That’s where small frequent meals come in handy. Consuming smaller portions of food more frequently throughout the day can help make it easier for your body to digest and manage the intake of nutrients.

The benefits of small frequent meals are numerous. First, they can help regulate blood sugar levels, preventing spikes and crashes that can leave you feeling lethargic or irritable. Second, they can help to reduce inflammation in the body, which is crucial when fighting off the flu. Finally, by consuming smaller, more manageable meals, you can ensure that you’re getting enough nutrients without overloading your system.

When planning your small frequent meals, focus on nutrient-dense foods that offer a range of vitamins and minerals. This might include whole grains, lean proteins, fruits, vegetables, and healthy fats. It’s also important to avoid processed foods and sugary snacks, as these can cause blood sugar imbalances and exacerbate inflammation.

If you’re struggling with appetite loss during the flu, consider incorporating high-calorie liquids like smoothies or soups into your meal plan. These can provide essential nutrients and calories without requiring extensive digestion.

Overall, small frequent meals are an excellent way to support your body during the flu and promote a speedy recovery. By focusing on nutrient-dense foods and avoiding processed junk, you can give your body the fuel it needs to fight off infection and restore your health.



In addition to eating nourishing foods, supplements may also be helpful in supporting the immune system while recovering from the flu. Three popular supplements that are recommended for boosting immunity are vitamin C, zinc, and probiotics.

Vitamin C

Vitamin C is a powerful antioxidant that helps protect cells from damage caused by free radicals. It is also essential for the production of white blood cells, which play a crucial role in fighting infections. While vitamin C cannot prevent the flu, it can help reduce the severity and length of symptoms. Good food sources of vitamin C include citrus fruits, berries, kiwi, and red peppers. However, if you are not getting enough vitamin C from your diet, taking a supplement may be beneficial. The recommended daily intake of vitamin C for adults is 75-90 mg, but some experts recommend higher doses (up to 2000 mg per day) during illness.


Zinc is an essential mineral that supports immune function and wound healing. It is involved in many cellular processes, including the production of DNA and the regulation of gene expression. Zinc deficiency has been linked to an increased risk of infections, so ensuring adequate intake may be particularly important during cold and flu season. Foods that are high in zinc include oysters, beef, pork, beans, and nuts. Zinc supplements are available in various forms, including lozenges and capsules. The recommended daily intake of zinc for adults is 8-11 mg for women and 11-14 mg for men. However, taking too much zinc can be harmful, so it’s important to follow dosing guidelines carefully.


Probiotics are beneficial bacteria that live in the gut and help maintain a healthy balance of microorganisms. They have been shown to improve digestion, boost immunity, and even reduce the risk of respiratory infections. Probiotic-rich foods include yogurt, kefir, sauerkraut, and kimchi. However, if you are not a fan of fermented foods, taking a probiotic supplement may be an option. Look for products that contain a variety of strains and at least 1 billion colony-forming units (CFUs). It’s also important to choose a reputable brand and store the supplement properly to ensure maximum potency.

In conclusion, while supplements should not replace a healthy diet, they can be a useful addition to support the immune system during illness. Vitamin C, zinc, and probiotics are three supplements that have been shown to have immunity-boosting properties. However, it’s always best to consult with a healthcare provider before starting any new supplement regimen, especially if you have underlying health conditions or take medications that may interact.
Eating the right foods when you have the flu can make a significant difference in your recovery time and overall well-being. Ginger, garlic, chicken soup, and hot tea are all excellent choices that can help alleviate symptoms and boost your immune system. On the other hand, avoiding processed foods, sugar, alcohol, and caffeine can prevent further inflammation and dehydration. Remember to stay hydrated, eat small frequent meals, and consider taking supplements like vitamin C, zinc, and probiotics. By following these tips, you can support your body’s natural healing process and bounce back from the flu faster. Take care of yourself and stay healthy!
