Weekly Health Quiz: How Your Body Makes GLP-1, Dangers of High Fat Diets, and Reducing Cancer Risk

1 How do fermented foods help the gut defend itself against harmful microbes?

• Higher pH levels make the intestines more neutral
• Lower pH levels create an environment hostile to pathogens
  

  Fermentation produces acids that lower gut pH, creating an environment where harmful microbes struggle to survive while beneficial species thrive. Learn more.

• Complete removal of gut bacteria prevents any microbes from staying
• Faster sugar absorption changes how the small intestine works

2 About how many people in the U.S. experience a stroke each year?

• 795,000
  

  More than 795,000 Americans experience a stroke each year, making it a leading cause of long-term disability, particularly in older adults. Learn more.

• 520,000
• 610,000
• 430,000

3 How does fermentation improve the availability of nutrients in foods?

• It removes all natural acids from food
• It reduces the food’s calorie content
• It makes vitamins easier for the body to absorb and use
  

  Fermentation breaks food components into forms your body can absorb more easily, boosting the bioavailability of nutrients, such as vitamins C, B12, and K. Learn more.

• It replaces nutrients with microbial byproducts

4 What percentage of daily calories from fats supports healthy hormone production?

• 10% to 15%
• 20% to 25%
• 45% to 55%
• 30% to 40%
  

  Keeping fat at about 30% to 40% of daily calories supports hormone production and nutrient absorption while avoiding the metabolic strain caused by excessive fat intake. Learn more.

5 Which condition is characterized by episodes of mania alternating with periods of depression?

• Panic disorder
• Seasonal affective disorder (SAD)
• Bipolar disorder
  

  Bipolar disorder involves mood swings between highs (mania or hypomania) and lows (bipolar depression). Depressive episodes may include persistent sadness, low motivation, slowed thinking, and brain fog. Learn more.

• Generalized anxiety disorder (GAD)

6 Which of the following is a serious side effect of long-term stomach acid suppression?

• Increased vitamin C levels
• Elevated glaucoma risk
• Reduced magnesium levels
  

  Long-term stomach acid suppression can lower magnesium levels and impair nutrient absorption, while also raising the risk of fractures, infections, and other health complications. Learn more.

• Higher oxygen levels

7 How does excess body fat raise your cancer risk?

• It prevents vitamins from being absorbed properly in the gut
• It releases inflammatory signals that support tumor growth
  

  Fat tissue releases inflammatory chemicals and disrupts metabolic function, creating conditions that support tumor growth. Learn more.

• It blocks protein from reaching muscle cells, causing sarcopenia
• It stops the body from making new mitochondria

8 Which statement best describes pink noise?

• A softer, deeper static sound similar to steady rushing water
  

  Pink noise concentrates more sound energy in lower frequencies, creating a gentle, water-like static often used in sleep sound devices. Learn more.

• High-pitched bursts that resemble electronic beeps
• Random volume spikes that change through the night
• Sharp rhythmic pulses designed to mimic fast heartbeats

9 Which hormone helps protect the brain from inflammation and oxidative stress?

• Cortisol
• Melatonin
• DHEA-S
  

  DHEA-S acts as a long-lasting buffer against chronic stress, helping the brain stay resilient when cortisol levels remain elevated. Learn more.

• Insulin

10 Which process does butyrate help suppress to protect brain cells?

• Rapid neuron firing during stress
• Neuroinflammation driven by NF-κB activity
  

  Butyrate helps suppress nuclear factor kappa B (NF-κB), a key regulator of inflammation, helping protect neurons and support healthy brain signaling. Learn more.

• Blood flow changes in the frontal cortex
• Loss of electrolytes during digestion

11 How does obesity affect macrophage activity during an infection?

• Faster responses that create excess strain in lung tissues
• Slower clearing of pathogens as macrophages lose efficiency
  

  Obesity-related inflammation pushes macrophages into a low-efficiency state, slowing pathogen removal and prolonging infection. Learn more.

• Reduced engagement with infected areas during respiratory stress
• Increased targeting of healthy tissues rather than invading microbes

12 What is the recommended daily intake of vitamin K2 for adults?

• 15 to 30 mcg
• 45 to 60 mcg
• 200 to 300 mcg
• 90 to 180 mcg
  

  For adults, the suggested daily range is 90 to 180 micrograms. Vitamin K2 helps direct calcium into bones, keeping it from accumulating in the arteries. Learn more.

13 Do children gain cognitive benefits from resistance training?

• Only if they train two hours daily at moderate intensity
• Only after early adulthood when muscle begins to form
• Yes, with small but steady improvements
  

  Children and teens experience modest but consistent improvements in cognition, behavior, and academic performance, with the greatest gains often seen in those with lower baseline muscular fitness. Learn more.

• No, benefits appear only in older adults

14 Which brain region showed inflammation-driven cell death after 5G exposure?

• Amygdala
  

  5G-related pyroptosis (an inflammatory form of cell death) was found in the amygdala, a region that helps regulate emotion, memory, and behavior. Learn more.

• Hippocampus
• Cerebellum
• Prefrontal cortex

15 What matters more than liver fat when predicting serious liver risk?

• Steatosis
• Fibrosis
  

  Fibrosis, or liver scarring, is the stronger warning sign because it reflects declining function and a higher risk of complications such as liver cancer better than fat accumulation alone. Learn more.

• Bile flow
• Hydration

16 Which age group saw the fastest rise in anxiety medication use?

• 35 to 49 years old
• 18 to 34 years old
  

  Young adults had the sharpest increase between 2019 and 2024, a shift linked to pandemic-related stress, financial pressure, and constant social media comparison. Learn more.

• 50 to 64 years old
• 65 years and older

17 How many adults in the U.S. aren’t getting enough sleep?

• 6 out of 10
  

  Data from the National Sleep Foundation show that 6 in 10 American adults do not get sufficient sleep, a pattern linked to gut disruption and higher metabolic risk. Learn more.

• 3 out of 10
• 1 out of 10
• 8 out of 10

18 What is the most convenient and effective way to use molecular hydrogen?

• Using hydrogen products steadily throughout the entire day
• Drinking hydrogen-rich water immediately after preparation
  

  Hydrogen-rich water, especially from tablets, works best when used right away because the hydrogen level falls quickly after preparation. Learn more.

• Taking hydrogen only after eating a large heavy meal
• Saving hydrogen water and drinking it much later on

19 What’s the best way to use information from wearables?

• Check and beat every score obsessively
• Treat the data as short-term feedback
  

  Wearable data is most useful as temporary guidance to learn your patterns, not as something to micromanage your day. Learn more.

• Let the device decide your daily schedule
• Compare your results to strangers online
