Weekly Health Quiz: Viral Shedding and Exercise

1 Which of the following is a major risk factor for vitamin D deficiency and severe COVID-19?

• High melanin density (darker skin)

  Darker skin requires far more sun exposure to produce adequate vitamin D, so much so that dark-skinned individuals living north of the equator are virtually guaranteed to be chronically deficient, which also increases their risk of severe COVID-19 illness and death. Learn more.

• Low melanin density (lighter skin)
• Low body weight
• Being under the age of 20

2 What percentage of the general population that has not been exposed to SARS-CoV-2 is still believed to be immune to the virus?

• 70-90%

  Between 40% and 60% of people who have not been exposed to SARS-CoV-2 still have resistance to the virus on the T-cell level. Learn more.

• 20-30%
• 0-10%

3 Which of the following nasal irrigation mixtures can help reduce the duration of the common cold and reduce transmission within the household by reducing viral shedding?

• Cold water only
• Warm sugar water
• Lukewarm water with table salt

  Nasal irrigation with hypertonic saline has been shown to reduce the duration of the common cold by 1.9 days and reduce transmission within the household by 35% by reducing viral shedding when done within 48 hours of symptom onset. Learn more.

• Hot water with rubbing alcohol

4 Low levels of these two compounds may increase the risk of depression among children and adolescents:

• Vegetable oil and trans fats
• Vitamin B12 and vitamin D

  Further, among the depression group vitamin B12 and vitamin D levels were "clearly low." Learn more.

5 An exercise session lasting just eight to 12 minutes leads to changes in biological processes related to:

• Energy metabolism, oxidative stress and inflammation

  In other words, in what is the most comprehensive study to date of the molecular changes that occur in your body due to exercise, providing an unprecedented glimpse into the details of the body's physiological response, it's demonstrated that "an orchestrated choreography of biological processes" occur, including those relating to energy metabolism, oxidative stress and inflammation. Learn more.

• Heavy metal detoxification
• Vitamin D production
• Nutrient intake

6 Which of the following supplements are given to National Health Service workers in the U.K. to help boost and regulate their immune function, thus lowering their risk of COVID-19?

• Vitamin K, calcium and magnesium
• Vitamins C, D and zinc

  The British Frontline Immune Support Team is providing U.K. National Health Service workers with free liposomal vitamin C, vitamin D and zinc to bolster their immune function and lower their risk of COVID-19. Learn more.

• Resveratrol and glutathione

7 Which of the following is the primary driver of macular degeneration and many other chronic diseases?

• Fluoridated water
• EMFs
• Industrially processed omega-6 vegetable oils

  There's compelling evidence that macular degeneration is not caused by aging or genetics but by processed foods. The four toxic ingredients in processed foods that cause mitochondrial dysfunction and chronic disease are refined wheat flour, refined added sugars, polyunsaturated vegetable oils and trans fats. Learn more.

• Glyphosate
