1Which of the following is NOT a glucagon-like peptide-1 (GLP-1) weight-loss drug?

• Ozempic
• Wegovy
• Mounjaro
• Xenical

  Xenical or Orlistat blocks fat absorption, while glucagon-like peptide-1 (GLP-1) drugs act on appetite and blood sugar regulation. Learn more.

2What is the fatty, waxy substance found in every cell of the body?

• Glucose
• Cholesterol

  Cholesterol is a waxy fat-like substance present in all cells. Most of it is made by the body, mainly in the liver, while a smaller portion comes from food. Learn more.

• Protein
• Calcium

3What was the most common issue reported in lawsuits involving GLP-1 drugs?

• Digestive injury

  Most lawsuits involve digestive problems, especially gastroparesis, where the stomach slows or stops moving food properly. Learn more.

• Skin irritation
• Vision problems
• Muscle weakness

4Which foods help support beneficial gut bacteria like Akkermansia muciniphila?

• Processed snacks and sugary drinks
• Fried foods (made with healthy oils) and refined grains
• Polyphenol-rich fruits and inulin-containing foods

  Foods like berries, garlic, and asparagus provide compounds that support beneficial gut bacteria and help maintain a healthy microbiome. Learn more.

• Natural sweeteners and homemade smoothies

5What elements make up baking soda?

• Sodium, calcium, oxygen, and nitrogen
• Sodium, hydrogen, carbon, and oxygen

  Baking soda, or sodium bicarbonate (NaHCO₃), is made of sodium, hydrogen, carbon, and oxygen. It helps maintain pH balance. Learn more.

• Carbon, oxygen, nitrogen, and sulfur
• Hydrogen, oxygen, calcium, and potassium

6Where is most of the klotho protein produced in the human body?

• Liver
• Kidneys

  Klotho is produced mainly in the kidneys and also in the brain. It helps reduce inflammation and supports healthy aging, brain function, and tissue repair. Learn more.

• Heart
• Lungs

7Why do aggressive diets increase metabolic stress?

• They release large amounts of stored fats into the bloodstream at once

  Extreme dieting speeds up fat breakdown, releasing large amounts of stored fats at once, which increases inflammation and metabolic stress. Learn more.

• They improve fat processing by making a person sweat more, leading to fat loss
• They lower energy demand and slow metabolic activity in the body
• They prevent fat from being used as fuel during energy production

8Which cells in the gut are responsible for producing protective mucus?

• Stem cells
• Immune cells
• Epithelial cells
• Goblet cells

  Goblet cells produce mucus that protects the gut lining. When these cells are reduced, the intestinal barrier weakens. Learn more.

9Which waste materials does the brain need to clear to stay healthy?

• Calcium and sodium
• Glucose and oxygen
• Beta-amyloid and tau proteins

  The brain clears beta-amyloid and tau proteins through the glymphatic system. Buildup of these wastes is linked to neurological diseases like Alzheimer’s. Learn more.

• Cholesterol and fatty acids

10What term describes a cell’s ability to adjust energy production when needed?

• Metabolic flexibility

  Metabolic flexibility is the ability of cells to adjust energy output. Aging brains lose this ability, making it harder to respond to stress and maintain function. Learn more.

• Cellular respiration
• Oxidative stress
• Energy storage

11Which type of meat is a better alternative to conventionally raised chicken?

• Farmed fish like tilapia
• Meat from ruminant animals like cows and sheep

  Ruminant animals like cows and sheep have unique digestion that helps reduce harmful fats, making them a better meat choice compared to grain-fed chicken. Learn more.

• Processed deli meats made using traditional, organic methods
• Grain-fed pork products

12Which of the following is not a heavy metal?

• Lead
• Mercury
• Aluminum

  Lead, mercury, and arsenic are classified as heavy metals linked to toxicity, while aluminum is not typically grouped with them in this context. Learn more.

• Arsenic

13Why are breast cancer survival rates higher in high-income regions?

• Access to early detection and effective treatment differs

  High-income regions detect cancer earlier and provide better care, leading to lower death rates than regions with limited access. Learn more.

• Genetic risk is higher in low-income countries
• Climate affects how breast cancer develops
• Lifestyle choices fully explain survival differences

14What type of strength is most important for preventing falls?

• Hip strength in the hip abductors

  Strong hip abductors help control side-to-side balance and stability, making it easier to step, recover, and avoid falls. Learn more.

• Arm strength in the shoulders
• Core strength in the abdomen
• Grip strength in the hands

15Which two vegetables were shown to remove most microplastics from water?

• Spinach and kale
• Carrots and cabbage
• Broccoli and cauliflower
• Okra and fenugreek

  Natural okra and fenugreek removed up to 93% of microplastics from water by trapping particles and helping them clump together for easier removal. Learn more.

16Which of these foods is also a good source of choline?

• Pastured eggs

  Pastured eggs are rich in choline, a nutrient linked to lower anxiety and better brain function, helping support a stable mood. Learn more.

• Cooked white rice
• Grilled chicken breast
• Unvetted olive oil

17How does cognitive shuffling help rewire your brain for better sleep?

• It trains the mind to stay completely silent before sleep
• It encourages focused thinking to prepare the brain for rest
• It trains the brain to associate repetitive thoughts with sleep

  Repeating simple, random thoughts helps the brain link this pattern with winding down. Over time, it becomes a cue that signals the body to relax and fall asleep. Learn more.

• It increases mental alertness to delay the onset of fatigue

18Which of these is not a symptom of an ingrown toenail?

• Redness around the nail
• Swelling and tenderness
• Improved nail growth

  Ingrown toenails cause redness, swelling, pain, and possible infection. Improved nail growth is not a symptom. Learn more.

• Pain or signs of infection

19Which cut of meat contains the least amount of collagen?

• Oxtail
• Beef shank
• Pork knuckle
• Tenderloin

  Tenderloin is a lean cut with very little connective tissue, so it contains less collagen compared to tougher cuts like shank or oxtail. Learn more.

20Which of the following is not a threat to cellular energy production?

• Seed oils high in linoleic acid
• Exposure to plastics
• Complex carbohydrates

  Seed oils, plastics, and electromagnetic fields (EMFs) can damage mitochondria. Complex carbohydrates support energy production and are not a threat. Learn more.

21How do low vitamin K2 levels affect calcium in the body?

• Calcium is fully absorbed into bones and strengthens them
• Calcium builds up in arteries while bones become weaker

  Without vitamin K2, calcium is not directed to bones and instead accumulates in arteries, leading to weaker bones and increased cardiovascular risk. Learn more.

• Calcium is completely removed from the bloodstream
