Learn the Reality of Adding Immune-Boosting Foods to a Diet

Fact: Garlic Can Help You Fight A Bacterial Infection

Bacteria are different, and eating garlic can help prevent, or at least help to mitigate, a bacterial infection. If you get infected with a virus, then eating garlic is unlikely to make things worse. However, it is unlikely to be a magic bullet that will prevent you from getting sick.

Regularly consuming garlic as part of a varied diet and healthy lifestyle can help keep your immune system functioning optimally. Instead of eating a clove of it raw to keep you from getting COVID-19, follow social-distancing guidelines, wear a mask when you leave the house, and take inventory of your entire lifestyle.

Myth: “Antibacterial” Foods Can Keep You Healthy

Half of the fat in coconut oil comes from lauric acid, a type of fatty acid with antimicrobial and antifungal effects. So if you want to kill off any pathogens inside of you, you should consume lots of coconut oil, right? Wrong.

To reap any antimicrobial benefits of coconut oil, you would have to guzzle so much of it that your heart would stop. Moreover, honey, which also has some antibacterial properties, is also a concentrated form of sugar. Not that you should skip these foods altogether, but don’t believe for a minute that they will improve your immune system.

Fact: All Food Should Be Consumed In Moderation

Coconut oil does have some health benefits, particularly regarding brain health. People with dementia have reported better outcomes in their memories when consuming coconut oil, but it is higher in saturated fat than butter. So while you can cook some food in coconut oil, you should limit how much you consume. And honey, primarily if it is produced from local flowers, can reduce the effects of seasonal allergies. Nevertheless, don’t consume too much of it, because it is very high in sugar. Other healthy foods that supposedly boost immune health should not necessarily be avoided, but they should be consumed in moderation.

Myth: You Should Not Consume Dairy When You Are Sick

This myth claims that dairy increases mucus production, and excessive mucus can clog the airways and harbor pathogens. While there is some truth to this claim, it is more myth than fact. There is simply no evidence to corroborate it.

Singers, public speakers, and others who rely heavily on a well-functioning throat may avoid dairy before an important event. However, they do not do so because they are trying to improve their bodies’ immune responses. They are trying to prevent a mucus build-up in their throats so that their voices are clearer.

Fact: Dairy Provides Necessary Proteins For Recovering

Dairy can cause extra mucus to line the throat, but it also provides nutrients that can help recover from illness. Amino acids, found in proteins, are an important part of immune health, and dairy has high protein levels.

Many dairy products are fortified with vitamin D, which helps the body absorb calcium. Vitamin D is critical for just about everything that the body does, including supporting its immune response and aiding in the recovery from illness. But if your experience is that dairy weighs you down, then go on and avoid it.

Myth: You Should Drink Juice When You Are Sick

When you start to feel the sniffles, your first impulse may be to pour yourself a glass of orange juice. However, you should be aware that orange juice is very high in sugar – it has more sugar, ounce for ounce, than soda – and doesn’t have the fiber that helps slow down the absorption of that sugar.

In other words, drinking orange juice can give you a sugar high, and sugar is the opposite of what you need to recover! The cells in your body can mistake sugar for vitamin C and accidentally bring the wrong molecule in. Drinking orange juice can make your flu worse. If all you can get down is a glass of juice, then sure, drink some juice. But don’t believe the myth that juice is beneficial.

Fact: Whole Fruit Has Many More Nutrients

Before oranges are juiced, they have fiber that helps slow down the absorption of sugar. So while you may be able to down three or four glasses of orange juice without noticing how much you have consumed, eating two or three oranges will leave you feeling full and satisfied.

Many nutrients are lost in the process of making fruit juice, not just the fiber. If you are a fan of juice and want to strengthen your body’s immune response, consider using a home juicer to juice your fruits, mixed with vegetables. Composting the leftover pulp and using it in a vegetable garden can boost your home-grown veggies’ nutrient content.

Myth: You Should Avoid Coffee And Tea When Sick

Coffee, tea, and other caffeinated drinks are diuretics, meaning that they cause you to have to urinate. Some people claim that drinking coffee makes them urinate more than the amount that they drank, a problem that can lead to dehydration if one consumes excessive amounts of coffee.

However, that doesn’t mean that you should avoid coffee and tea when you are sick (however, you should prevent artificially caffeinated drinks, like soda). Coffee lovers and tea drinkers can rest happily knowing that they do not have to forfeit their favorite beverage to feel better next time they get sick.

Fact: Coffee And Tea Have Many Health Benefits

The antioxidants found in coffee and tea far outweigh the temporary side effect of having to urinate more frequently. Studies have shown that people who regularly consume coffee and tea (especially green tea) have improved cardiovascular health, lower rates of cancer, and better cognition (especially among Alzheimer’s patients) than those who do not.

Drinking coffee when you are under the weather is unlikely to make you feel better, beyond it being a comfort food that can provide an emotional boost. Furthermore, if you need extra sleep, you may want to reduce the caffeine. But ultimately, it will do more good than bad.
