1 Research shows that if you have enough — a level of 10 percent or more — of the following cells in your body, you will not contract influenza:
- Red blood cells (erythrocytes)
- White blood cells (leukocytes)
- Stem cells
- Natural killer cells
Beta-glucans found in mushrooms enhance NK cell activity and function, and research shows that if you have enough NK cells in your system, you will not contract influenza. Learn more.
2 Which of the following is not a source of nitrogen pollution?
- Dental office wastewater
Communities near hog CAFOs have higher mortality rates from anemia, kidney disease, tuberculosis and septicemia, as well as higher infant mortality, likely due to exposure to hog waste. Learn more.
- Animal manure
- Fertilizer runoff
- Slaughterhouse wastewater
3 Water exists in how many different states?
Research shows water exists in four different states: solid (ice), liquid, vapor and H3O2, a negatively charged, viscous form of “living” water that holds and delivers energy. This fourth state of water may have important implications for the field of homeopathy. Learn more.
4 Mounting research strongly suggests the following diet is protective against the neurological degeneration associated with Alzheimer’s disease:
- Mediterranean diet
- Vegan diet
- Ketogenic diet
Recent animal research shows a ketogenic diet improves neurovascular function, in part by improving the gut microbiome. These findings add further support to previous findings showing a high-fat, low-net carb diet promotes brain health and protects against neurodegeneration. Learn more.
- DASH (low salt) diet
5 Which of the following types of exercises has been shown to lower blood pressure most effectively?
- Aerobic exercise such as walking and running
- Strength training
- Low-impact exercise such as swimming
- Isometric handgrip training
Research suggests improving your handgrip strength may be the most effective way to lower your blood pressure — even more effective than conventional endurance and strength training programs. Learn more.
6 An infant is inoculated with crucial health-promoting bacteria and microbes for the first time during:
- Vaginal birth
Bacterial colonization begins at birth, as the baby travels through the birth canal, and things like birth by cesarean section, antibiotic use, bottle feeding instead of breastfeeding and excessive hygiene can all impair a child’s immune function by limiting exposure to beneficial bacteria. Learn more.
- Breast feeding
- Feeding of first solid foods
7 A low-histamine diet requires the elimination of which general category of healthy food?
- Fruits and vegetables
- Fermented foods
What may appear to be nonceliac gluten sensitivity may actually be a histamine intolerance. A low-histamine diet can seem paradoxical as it eliminates fermented foods, which are otherwise known to improve gut health. Learn more.
