Weekly Health Quiz: Shattering Keto Myths, Getting to Know Urolithin, and Alcohol Brain Bleeds

1 What does the “fiber paradox” suggest about gut health?

• Fiber can backfire if the gut isn’t ready to ferment it properly
  

  In a damaged gut, fiber might feed harmful bacteria instead of helpful ones, worsening symptoms like bloating and preventing butyrate production. Learn more.

• Most fiber passes through the gut unused, regardless of condition
• Fiber works best when paired with high-protein meals
• Healthy microbiomes need zero fiber to produce butyrate

2 What now makes up more than half of the calories U.S. adults eat at home?

• Takeout foods from organic restaurants
• Fresh foods cooked from basic ingredients
• Ultraprocessed food made by big companies
  

  Ultraprocessed foods now supply over half of at-home calories for U.S. adults, crowding out healthier foods and increasing the risk of chronic disease. Learn more.

• Traditional diets based on whole foods

3 Which simple food swap helps restore gut balance and butyrate production?

• Replacing carbs with protein shakes for fitness
• Having an occasional serving of homemade yogurt
• Avoiding all fats to improve digestion and lose weight
• Swapping seed oils for healthy fats like ghee
  

  Seed oils disrupt the microbiome, while stable fats support gut cells and microbial balance, helping restore butyrate production naturally. Learn more.

4 How should fiber be added to increase butyrate production without worsening gut problems?

• Add large amounts of raw fiber immediately to overwhelm harmful gut bacteria
• Eliminate carbohydrates so gut bacteria are forced to adapt more efficiently
• Use fiber supplements first to crowd out endotoxin-producing microbes
• Restore gut balance with easy carbohydrates before increasing fiber intake
  

  When the gut is damaged, fiber feeds harmful bacteria. Rebuilding a low-oxygen, balanced microbiome first allows fiber to boost butyrate safely. Learn more.

5 When does occasional trouble sleeping become chronic insomnia?

• When sleep issues appear during life changes but fade within weeks
• When sleep trouble occurs at least three nights a week for over three months
  

  Chronic insomnia is diagnosed when sleep problems happen at least three nights a week and persist for over three months, beyond temporary causes like stress or diet. Learn more.

• When feeling tired after sleep happens once or twice during stressful periods
• When falling asleep becomes harder only after screen time or heavy meals

6 How do everyday chemicals like pesticides and plastics affect your gut?

• They act like antibiotics that kill helpful gut bacteria
  

  Many common chemicals behave like antibiotics in the gut, killing beneficial bacteria that support digestion, immunity, and metabolic health. Learn more.

• They increase stomach acid to improve digestion
• They only affect gut bacteria at very high doses
• They weaken the gut lining by allowing microbes to flourish

7 What is the primary source of butyrate, the real histone deacetylase (HDAC) inhibitor in your gut?

• Made from sugar in the liver after eating high-quality protein
• Produced by gut bacteria breaking down fiber you eat
  

  Gut bacteria make butyrate by digesting fiber, not from fat or sugar metabolism. Learn more.

• Created by your muscles when you exercise every day
• Made by the brain during times of stress or worry

8 About how many Americans are diagnosed with lung cancer each year?

• Roughly 75,000 people nationwide
• Just over 120,000 new cases annually
• More than 235,000 people each year
  

  Lung cancer diagnoses exceed 235,000 annually in the U.S., making it one of the most commonly diagnosed and deadliest cancers nationwide. Learn more.

9 Which factor directly weakens tendon collagen and raises the risk of Achilles rupture?

• High-intensity sprint drills done without proper warmup
• Long-term wear of unsupportive minimalist running shoes
• Use of certain drugs like fluoroquinolone antibiotics or corticosteroids
  

  Fluoroquinolone antibiotics and corticosteroids can degrade tendon collagen, making tendons more prone to tearing — especially with repeated or high-dose use. Learn more.

• Inherited tendon length differences that affect natural foot mechanics

10 In addition to urolithin A, which habit can help support your mitochondria?

• Supporting nicotinamide adenine dinucleotide (NAD⁺) production with niacinamide
  

  By lowering consumption of seed oils and supporting NAD⁺ with niacinamide, you help mitochondria make energy and reduce cellular damage. Learn more.

• Raising healthy fat intake and minimizing all dietary carbohydrates long-term
• A controlled, gradual increase in exposure to environmental toxins for stronger immune signaling
• Replacing all animal fats with processed seed oils for metabolic health

11 Which sweetener is linked to hidden fat buildup in the liver?

• Aspartame, found in most diet sodas and sugar-free gums
• Sorbitol, a sugar alcohol that turns into liver-damaging fructose
  

  Sorbitol turns into fructose in your liver, where it causes fat buildup — even if your gut bacteria are healthy. This raises your risk of fatty liver disease over time. Learn more.

• Stevia, a natural plant extract used in low-calorie sweeteners
• Erythritol, a zero-calorie sweetener that your body flushes out unchanged

12 What is parcopresis?

• The inability to have a bowel movement in public due to anxiety
  

  Parcopresis, or “shy bowel,” happens when social anxiety makes it feel impossible to poop in public restrooms. The body stays tense, and normal bowel reflexes shut down. Learn more.

• Having weak bladder muscles that make it hard to urinate fully
• Getting constipation from eating too little fiber or drinking too little water
• Losing bowel control during moments of sudden stress or fear

13 Which of the following is not a practical step to protect your child in today’s digital world?

• Providing smartphone access early to cultivate emotional maturity
• Keeping devices out of the bedroom to support deeper, more restful sleep
• Giving your child more screen time to improve their ability to self-soothe
  

  More screen time doesn’t teach self-soothing — it increases stimulation and stress. Limiting exposure and building healthy habits supports emotional resilience and better sleep. Learn more.

• Replacing Wi-Fi with wired connections to reduce wireless radiation exposure

14 Why do glucagon-like peptide‑1 (GLP‑1) weight‑loss drugs often lead to hair loss?

• They block scalp blood flow, slowly starving hair follicles of oxygen over time
• They raise testosterone levels, triggering genetic pattern baldness prematurely
• They create metabolic stress that pushes hair into a resting shed phase
  

  Rapid weight loss and calorie suppression signal internal stress, forcing hair follicles into telogen effluvium, a stress-driven shedding response rather than permanent hair loss. Learn more.

• They directly poison hair follicles through drug buildup in scalp tissue

15 What is one goal of the U.S. Department of Agriculture’s (USDA) new $700 million Regenerative Pilot Program?

• To expand sustainable farming methods that prioritize high crop yields
• To support farmers switching to soil-friendly, regenerative practices
  

  The USDA’s program helps farmers move toward regenerative farming, which builds healthier soil, improves food quality, and reduces the need for chemicals. Learn more.

• To grow industrial farms that supply ingredients for the organic food industry
• To encourage centralized, organic food systems over smaller, local farm networks

16 What makes calisthenics a good long-term fitness option for most people?

• It uses advanced gym equipment and heavy loads for maximum results
• It focuses only on cardiovascular health, not strength
• It works best for athletes with high mobility
• It’s simple, adaptable, and easy to stay consistent with
  

  Calisthenics is sustainable because it uses bodyweight movements anyone can adjust and stick with over time. Learn more.
