It’s that time again! Time for another installment of Intelligent Medicine’s “Test Your Health IQ” quiz. You can also test your knowledge in our previous quizzes, part one and part two.
According to an article in The Los Angeles Times, American adults get a “D” in science. In fact, 22% confuse astronomy and astrology! On a general science knowledge quiz consisting of 12 questions, the test-takers answered 7.9 correctly, on average. That’s a score of 66%. Only 6% answered all 12 questions correctly.
Similarly, lack of health literacy is also a huge problem among Americans. We are continually bombarded with often-contradictory health information. U.S. patients are confronted with a myriad of treatment options that they are ill-equipped to properly choose among. Urban legend, aggressive direct-to-consumer advertising, and dumbed-down media stories add to the confusion.
The mission of Intelligent Medicine is to enhance your health IQ. Here’s a third, all-new installment of our Health Quiz. See if you get a “Pass!”
1. The following are reasons for a chronic persistent cough EXCEPT:
2. Which statement most accurately describes the relationship between the gut and the brain:
3. All of the following support cellular energy metabolism EXCEPT:
4. Which of the following nutrients can dangerously over-accumulate in patients with kidney failure?
5. ALL of the following reflect the professional esprit of many U.S. physicians EXCEPT:
6. All of the following are harmful effects of even moderate alcohol consumption EXCEPT:
7. Recently disproven medical dogmas include all of the following EXCEPT:
8. High-dose vitamin D has been demonstrated to be effective for all EXCEPT:
9. Which of the following statements about the Paleo Diet is incorrect:
10. Which of the following has NOT been demonstrated to be helpful for Parkinson’s Disease:
ANSWERS:
1. E) All of the above; GERD is a newly-recognized cause of chronic cough.
2. E) All of the above; The gut-brain connection is now acknowledged to be a two-way street.
3. E) All of the above.
4. D) Magnesium, can dangerously accumulate in patients with reduced kidney filtration.
5. A) Surveys show that electronic health records (EHRs) and office automation are a major source of physician dissatisfaction.
6. B) While alcohol reduces the risk of coronary artery disease, and hence heart attacks, it may increase the risk of atrial fibrillation.
7. A) Unfortunately, women with a BRCA gene mutations may be at such higher risk of ovarian cancer that hysterectomy may be warranted. The lifetime risk of ovarian cancer is 20%–46% for BRCA1 mutation carriers and 10%–27% for BRCA2 mutation carriers.
8. This is kind of a trick question. I’ll accept either C) or E) for an answer. Excess vitamin D may INCREASE the risk of kidney stones (vitamin D greater than 10,000 IUs per day) but there is a unique condition called secondary hyperparathyroidism, which usually occurs in the setting of kidney dialysis, where the risk of stones can be diminished with aggressive vitamin D therapy. A new study suggests the risk of kidney stones with even high vitamin D supplementation may be exaggerated
9. A) While it may seem counterintuitive, the anti-inflammatory, blood sugar-regulating effects of the Paleo Diet make it ideal for heart disease prevention and reversal.
10. C) Unfortunately, while it showed promise in early trials vs. Parkinson’s, vitamin E was deemed ineffective in the large DATATOP trial. However, the vitamin E used was alpha tocopherol, so it may be that mixed tocopherol or gamma-tocopherol E may eventually be proven beneficial as potent brain antioxidants.
If you answered all these questions correctly, or even 9 out of 10, congratulations, you are a true paragon of Intelligent Medicine! If you got 7 or 8 right, you’re still doing better than average. If you scored 60% or less, your health literacy needs a boost. Try boning up on medical and nutritional facts by listening to our Intelligent Medicine podcasts and following the articles we post at DrHoffman.com—you’re sure to ace the test when we repeat it sometime next year!
