There is literally never a good time to get sick. Between work, life, and trying to function as a human being, a cold or virus is a wrench in the gears that none of us need.
Naturally, when the sniffles start circulating, the instinct is to panic-buy the entire pharmacy aisle. But before you stock up on neon-colored syrups, look at your fridge. Real food is your body’s first line of defense.
We’re talking about antiviral foods. Ingredients that don't just taste good but actually armor you up against threats. To give you the facts without the fluff, we’ve pulled the science-backed data on 7 natural powerhouses that inhibit viral replication and boost immunity.
Here is the breakdown of nature’s best defenders (and why you need them in your antiviral diet ASAP).
1. Black Tea
Is rich in a group of pathogen-fighting compounds that can protect against a variety of viral infections. Tea leaves contain naturally occurring compounds—including polyphenols, catechins, and alkaloids such as caffeine, theobromine, and theophylline—that defend the plants against invading bacteria, fungi, and viruses. Research shows that black tea can almost completely inhibit the infectivity of influenza virus. And in one study, black tea extract rich in flavanol compounds called theaflavins inhibited herpes simplex virus type-1 (HSV-1) infection.
Try this: Purée strong-brewed black tea with grated ginger, frozen mango, and Greek yogurt for a flu-busting breakfast; steep black tea bags in hot water, then use as a broth to cook brown rice, garlic, and onions; finely grind loose black tea (try Earl Grey) and add to lemon or banana muffin batter before cooking.
2. Garlic
Contains powerful compounds—including allicin, diallyl trisulfide, and ajoene—that fight viruses, including influenza, rhinovirus, cytomegalovirus (a type of herpes virus), herpes simplex, HIV, viral pneumonia, and rotavirus. In one study, people who took allicin extract over a 12-week period had significantly fewer colds than a placebo group, and those who did get a cold recovered faster.
Try this: Roast whole heads of garlic, skin-on, until cloves are soft, then let cool and peel off skins; finely mince raw garlic and add to a dressing of olive oil, lemon juice, and minced thyme; press or mash raw garlic cloves and mix with minced rosemary and coconut oil, then refrigerate until firm for a pungent vegan spread.
3. Shiitake Mushrooms
Are loaded with beta-glucans, antiviral compounds that have been shown to inhibit viral replication and enhance immune function. In one study, people who ate shiitake mushrooms for four weeks showed improved markers of immunity, as well as reduced inflammation. Other studies have shown that shiitake mushrooms have significant antibacterial and antifungal properties, and protected against 85 percent of the yeasts, molds, and other organisms it was tested on.
Try this: Thinly slice shiitake mushroom caps, toss with melted coconut oil and minced garlic, and roast until crispy; sauté whole shiitake mushroom caps and leeks in olive oil, then finish with balsamic glaze; stir-fry shiitakes, slivered carrots, broccoli, sliced red peppers, and minced ginger in sesame oil and tamari, then toss with cooked soba or rice noodles.
4. Ginger
Has long been used in tradi-tional medicine to treat colds and flu, and modern studies show that it has measurable antiviral benefits. In one study, fresh ginger protected against HRSV (human respiratory syncytial virus, a major cause of lower respiratory tract infections), by blocking the virus’ ability to attach to cells and stimulating the release of compounds that help counteract viral infections.
Try this: Cut peeled ginger root into matchsticks, sauté in olive oil until crispy, and use as a topping for soups or salads; simmer ginger slices in milk or coconut milk, strain, then whisk in turmeric and honey for a creamy, soothing beverage; combine finely grated ginger, dates, walnuts, and coconut in a food processor, process to make a paste, then roll into balls for quick energy treats.
5. Apple Cider Vinegar
Is another traditional antiviral, and a number of modern studies have established the antimicrobial activity of apple cider vinegar against a variety of pathogens. Researchers suggest that apple cider vinegar may work by a variety of mechanisms, including the antiviral properties of apples and the presence of probiotics that occur during the fermentation process.
Try this: Steep dried elderberries and sliced ginger in apple cider vinegar, then strain and add honey for an easy oxymel (herbal tonic); whisk together apple cider vinegar, honey, mustard, and olive oil for a sweet, creamy dressing; stir apple cider vinegar and agave into hot water and pour over sliced onions and ginger for quick pickles.
6. Cinnamon
Has been used in herbal medicine for hundreds of years, and chemical profiling shows that its active compounds have antiviral, antimicrobial, immunomodulatory, and anti-inflammatory effects. In one study, cinnamaldehyde, the compound that gives cinnamon its characteristic flavor and smell, inhibited the growth of the influenza virus. Cinnamaldehyde also inhibits Listeria and Escherichia coli in foods, and protects against a variety of yeasts and fungi, including Candida albicans.
Try this: Add cinnamon, cardamom, vanilla extract, and coconut milk to oatmeal for a chai-spiced breakfast; toss sliced apples and pears with cinnamon and honey, sauté in coconut oil, and top with toasted pecans; add cinnamon and cocoa powder to your morning coffee.
7. Yogurt
Contains probiotics that fight viral infections. In one review, 28 trials showed that probiotics protected against respiratory tract infections. Other studies have found that probiotics can enhance respiratory tract immunity, speed recovery, and lessen the severity of respiratory infections caused by the influenza virus. Probiotics may protect against other viral infections, including some types of Coxsackievirus, HIV-1, and viruses that cause diarrhea.
Try this: Mix Greek yogurt with mashed avocado, minced red onions, and cumin for a creamy sandwich spread; whisk yogurt with apple cider vinegar, dried dill, and minced garlic and chives for a delicious healthy dressing.
