Drink a Lot of Liquids

The cold and flu viruses thrive in a dry environment. This is why it’s doubly important that you drink a lot of liquids to keep your throat and nasal passage lubricated. The mucous membranes in the said areas need to be moist in order to properly trap any viruses attempting to enter your body. More than that, drinking liquids can flush down these viruses into your stomach so they’re easily killed without having a chance to compromise your immune system.

Have Some Garlic

Garlic is a good source of allicin -- a powerful antimicrobial that doesn’t just fend off viruses, but fungi and bacteria as well. A good way to harvest this antimicrobial into your body is to chew on a garlic clove every couple of hours (around 3 to 4). If you can’t take the pure taste of garlic, you can just add it to your soup, but before you do so, make sure you let it sit for 15 minutes before adding it to your dish.This will ensure that its antibacterial agents have a chance to act before being consumed.

Eat More Fish

Eating fish rich in omega-3 fatty acids is a great way to prevent inflammation in your body, which leads to a stronger immune system, as an improperly functioning one is more susceptible to the cold and flu viruses. Alternatively, you can also take fish supplements with the said mineral so that you get enough omega-3 fatty acids in your everyday diet during this season.

Snack on Citrus Fruits

Citrus fruits consumption like orange, lime, lemon and grapefruits is a great way to fight colds and flu. The common compound in these fruits, Vitamin C, help fortify your immune system so viruses can’t easily invade your body. Best of all, there’s no such thing such as Vitamin C overdose because your body will just flush out any excess it doesn’t need.
