Weekly Health Quiz: Glyphosate's Dirty Secret, Secrets to Better Brain Health, and Brain Rot Basics

1 Why should regulatory claims about glyphosate safety be questioned?

• Key studies with secret industry backing were retracted
  

  Confidence in glyphosate safety is weakened when key studies are retracted for ethical reasons and hidden industry ties. Learn more.

• Regulators have banned all research on glyphosate for profit motives
• Organic farmers control most of the published studies
• Safety claims are based only on animal testing and not human consumption

2 Why is it hard to get much thymoquinone from black cumin seed oil?

• The oil is hard to find
• Thymoquinone is destroyed by cooking
• There’s very little thymoquinone in the oil
  

  Thymoquinone is the main beneficial compound in black cumin seed oil, but only tiny amounts are present in the oil. Learn more.

• Most brands add sugar, which disrupts the chemical makeup

3 What is one effective way to reduce glyphosate exposure?

• Choosing organic or regeneratively farmed foods
  

  Eating organic or regeneratively farmed foods helps lower glyphosate exposure by avoiding crops treated with herbicides. Learn more.

• Rinsing all produce with hot water to remove residue
• Avoiding all fresh fruits and vegetables sold in grocery stores
• Taking daily vitamin supplements to increase antioxidant effectiveness

4 Which activity is most reliable for long-term brain health?

• Heavy weightlifting
• Daily sprint intervals
• Marathon training
• Regular moderate walking
  

  Moderate, consistent walking is linked to slower brain decline and fewer metabolic problems. Learn more.

5 Which is a recommended way to avoid per- and polyfluoroalkyl substances (PFAS) in cosmetics?

• Check labels for “perfluoro-” or “polyfluoro-”
  

  Checking for “perfluoro-” or “polyfluoro-” on labels is the most direct way to avoid per- and polyfluoroalkyl substances (PFAS) in cosmetics. Learn more.

• Choose only fragrance-free beauty products
• Wash your face more often with cold water
• Buy products labeled “hypoallergenic”

6 What opportunistic pathogen often rises in the gut after a colonoscopy?

• Bacteroides
• Lactobacillus
• Firmicutes
• Proteobacteria
  

  Proteobacteria thrive when the gut is disrupted, quickly taking advantage of higher oxygen and stress after procedures like colonoscopies. Learn more.

7 Which approach is most effective for rebuilding focus?

• Relying on willpower alone
• Ignoring phone use and multitasking
• Creating focus blocks
  

  Changing your environment and setting daily focus periods helps restore attention better than relying on willpower. Learn more.

• Taking daily memory supplements

8 Why do vision problems often appear before heart symptoms?

• Large arteries handle stress longer than small vessels in the body
• Eyesight conditions need more time to develop than chest pain
• Heart and eye symptoms always appear together
• Small eye vessels show damage from poor blood flow sooner
  

  Tiny blood vessels in the eyes are affected by poor circulation before larger heart arteries show problems. Learn more.

9 How many Americans are affected by Type 2 diabetes?

• Fewer than 5 million
• About 8 million
• Nearly 18 million
• Over 38 million
  

  More than 38 million Americans have Type 2 diabetes, and the number keeps rising. Learn more.

10 Which combination of exercise produces the strongest improvements for fatty liver disease?

• Stretching, flexibility exercises, and some calisthenics
• Aerobic exercise combined with resistance training
  

  Combining aerobic and resistance exercise improves fat burning, insulin signaling, and blood sugar regulation more effectively than either exercise type alone. Learn more.

• Resistance training without cardiovascular activity
• Light walking performed a few times per week

11 Which kind of fat is most strongly linked to low vitamin D levels?

• Visceral fat
  

  Visceral fat, stored deep around organs, has the strongest association with low vitamin D levels. Learn more.

• Subcutaneous fat
• Fatty acids
• Neck fat

12 Which neurotransmitter helps with memory, attention, learning, and emotional regulation?

• Dopamine
• Acetylcholine
  

  Acetylcholine supports memory, attention, learning, and mood by helping nerve cells communicate. Learn more.

• Serotonin
• GABA

13 Which substance found in plaques explains why clots resist breaking down?

• Low-density lipoprotein (LDL) or bad cholesterol
• Red blood cells
• Lipoprotein A
  

  Lipoprotein A helps patch artery damage but makes clots harder to dissolve, promoting plaque buildup and raising heart attack risk. Learn more.

• Dietary fats

14 Which of these isn’t released by microbes from fermented foods?

• Acids
• Enzymes
• Metabolites
• Hormones
  

  Fermented food microbes release acids, enzymes, and metabolites — but not hormones — when passing through your gut. Learn more.

15 What role does brain-derived neurotrophic factor (BDNF) play in mental health?

• It slows down brain development in childhood
• It raises stress hormones during anxiety
• It blocks new connections between brain cells
• It supports learning, mood stability, and stress resilience
  

  BDNF helps brain cells grow and connect, promoting learning, stable mood, and the ability to handle stress. Learn more.

16 Which cancer-related complications have the strongest clinical support for photobiomodulation (PBM)?

• Fatigue and nausea from chemotherapy
• Oral mucositis and radiation-related skin damage
  

  Clinical research shows PBM is especially helpful for easing pain and healing mouth sores and skin reactions caused by cancer treatment. Learn more.

• Hair loss and immune suppression
• Infection risk and blood cell loss

17 What hormone is commonly known as the “bonding hormone”?

• Oxytocin
  

  Oxytocin is called the “bonding hormone” because it promotes connection and lowers stress. Learn more.

• Cortisol
• Insulin
• Adrenaline

18 What happens to the brain when someone has long-term high blood pressure?

• Attention and learning get a measurable boost
• More oxygen reaches all brain regions over time
• Blood flow drops and memory-related areas shrink
  

  Long-term high blood pressure reduces brain blood flow and shrinks areas critical for memory, focus, and decision-making. Learn more.

• Nerves controlling relaxation become more active

19 Which of the following is not considered a real food alternative to Big Food?

• EatWild.com and Local Harvest
• Digital farmers market platforms
• Pasture-based meat and raw dairy
