"If you're in contact with coronavirus, it doesn't matter how many oranges you eat, you're going to get it," Dr. Caroline Apovian, Director of the Nutrition and Weight Management Center at Boston Medical Center, previously told Business Insider.
It is true that malnutrition can impair your ability to fight off illness and infection, but if you eat an otherwise balanced diet, loading up on specific "super" foods like kale, berries, or anything else won't provide any additional benefits.
Following common-sense dietary advice is enough to keep your immune system in good shape, no superfoods required, according to Apovian.
While sugar and heavily-processed foods are linked to chronic health issues over time, there's no evidence that a single donut is going to increase your risk of catching a virus.
Unless you have a nutritional deficiency, experts say no amount of vitamin shots, juices, or infusions will prevent you from getting sick if you come into contact with a pathogen like the coronavirus.
Some popular Youtube naturopath have recommended IV doses of vitamins A and C that are up to 15,000 milligrams a day, 166 times the recommended daily amount for men, and shots of vitamin D3 up to 160 times the recommended daily dose, Insider previously reported.

These extremely high doses can cause serious side effects like dizziness, nausea, and headaches. Even more alarming consequences include damage to organs like the kidneys and liver, possible coma, and even death.
Colloidal silver, tiny particles of metal in liquid that's sold as a dietary supplement, has been advertised online to fight bacteria and viruses as well as treat diseases from HIV and cancer to herpes and shingles.
None of these claims are backed by any evidence, however, according to the National Institute of Health and the Mayo Clinic.
And the side effects include condition called argyria, or permanent blue-gray discoloration of the skin, and possibly kidney damage. Colloidal silver can also interfere with the absorption of certain medications.
A substance called miracle mineral solution (MMS) has been advertised in some fringe communities as a cure-all, and is making the rounds again as a means to prevent or heal coronavirus.
In reality, MMS (sometimes called chlorine dioxide) is an industrial bleach, and people have severe vomiting, diarrhea, life-threateningly low blood pressure, and acute liver failure after drinking the concoction.
According to the FDA, there is no research that shows MMS to be an effective treatment, cure, or prevention for any illness, coronavirus or otherwise.
