  Gamma-aminobutyric acid (GABA) slows excessive brain activity, helping regulate mood, sleep, and stress. Low levels are linked to anxiety, poor sleep, and neurological issues. Learn more.

6 How does honey help relieve throat inflammation?

• It increases mucus production in the throat
• It dries out the throat to reduce irritation
• It coats the throat and suppresses coughing

  Honey coats the throat and acts as a natural cough suppressant, helping reduce inflammation and irritation, especially at night. Learn more.

• It blocks all bacteria instantly in the airway

7 What type of foods may help rebuild the gut after antibiotic use?

• Highly processed foods and refined sugars
• Simple whole foods, including complex carbohydrates

  Simple whole foods with complex carbohydrates help restore gut bacteria, support the gut lining, and improve overall microbial balance after antibiotics. Learn more.

• High-fat foods that follow the principles of the ketogenic diet
• Artificial sweeteners and packaged snacks

8 How many Americans are affected by arthritis?

• 53.2 million

  About 53.2 million Americans live with arthritis, making it one of the most common causes of joint pain, stiffness, and reduced mobility. Learn more.

• 10.8 million
• 23.1 million
• 80.9 million

9 Why may fruits help protect against tinnitus?

• They increase blood sugar for energy
• They improve digestion in the stomach
• They add more calories to the diet
• They provide antioxidants that protect ear cells

  Fruits are rich in antioxidants like vitamin C and polyphenols, which help reduce oxidative stress and protect the inner ear from damage linked to tinnitus. Learn more.

10 Which of the following is a source of unhealthy fats in modern diets?

• Organic fruits
• Pastured eggs
• Restaurant meals

  Restaurant meals and packaged chips are often cooked in seed oils high in unhealthy fats. Organic fruits contain little to no fat, making them an unlikely source. Learn more.

• Home-cooked whole foods

11 How much creatine does the body naturally produce each day?

• 1 to 2 grams

  The body produces about 1 to 2 grams of creatine daily from amino acids, helping support cellular energy and overall function. Learn more.

• 5 to 10 grams
• 10 to 15 grams
• 0.5 grams

12 What is the active ingredient in Benadryl?

• Diphenhydramine

  Benadryl contains diphenhydramine, an older antihistamine that can cause sedation and other side effects, with newer alternatives now considered safer. Learn more.

• Loratadine
• Cetirizine
• Fexofenadine

13 What type of fat is stored deep around your organs and drives inflammation?

• Subcutaneous fat
• Brown fat
• Intramuscular fat
• Visceral fat

  Visceral fat surrounds organs and releases inflammatory signals, disrupting blood sugar control and increasing the risk of liver damage over time. Learn more.

14 What is the most common cause of tight hips?

• Drinking too much water
• Sleeping too many hours
• Prolonged sitting

  Sitting for prolonged periods keeps hip flexors shortened and weakens glutes, reducing blood flow and leading to stiffness and poor movement control. Learn more.

• Eating a high-protein diet

15 What process triggered by intermittent fasting contributes to hair loss?

• Lipolysis

  Intermittent fasting increases lipolysis, releasing fatty acids that create oxidative stress, which can damage hair follicle stem cells and disrupt hair growth. Learn more.

• Glycolysis
• Protein synthesis
• Cell hydration

16 What is the main function of fibroblasts in the body?

• They produce hormones that regulate metabolism
• They break down damaged cells in tissues
• They transport oxygen through the bloodstream
• They produce collagen to build connective tissue

  Fibroblasts are repair cells that produce collagen, helping form and maintain connective tissue, but excess activity can lead to tissue thickening. Learn more.

17 How much protein is recommended after a workout?

• About 20 to 40 grams

  Consuming 20 to 40 grams of protein after exercise supports muscle repair and recovery when muscles are most ready to absorb nutrients. Learn more.

• About 5 to 10 grams
• About 50 to 70 grams
• No protein is needed

18 Which of the following does not cause exercise headaches?

• Increased blood flow to the head
• Rapid rise in workout intensity
