3 What do you call the artery lining that can get damaged and trigger clot formation as a “patch”?

The endothelium is the inner lining of arteries, and when it’s injured, your body forms a clot to seal the spot until repair cells rebuild the lining. Learn more.

Avoid all carbs, eat only lean meat, and add more artificial sweeteners
Take large probiotic doses daily and stop eating all meats to stimulate probiotic growth
Skip fiber completely, increase healthy fats, and rely on natural fruit juices
Start with easy-to-digest carbs, then add resistant starch and inulin slowly
Butyrate is made when microbes ferment fiber, so you build tolerance first, then feed butyrate-producers with resistant starch and inulin gradually. Learn more.

2 Which kind of cells get reprogrammed by tick saliva to weaken immune defense at the bite site?

Foam cells
Mast cells
Langerhans cells
Tick saliva alters Langerhans cells in the outer skin so they leave the bite site and become more tolerant, delaying the early immune alarm while microbes spread. Learn more.
Natural killer (NK) cells

3 Which of these foods does not help your body make more butyrate?

Candy and sugary soda
Candy and soda don’t feed butyrate-producing bacteria and can worsen gut imbalance, while fermented foods support butyrate-making microbes. Learn more.

20,000 FU
25,000 FU

8 Why are ultrafine particles from vaping especially concerning?

They dissolve instantly in saliva and never reach your lungs
They mainly irritate the nose and stop before the throat
They can reach the alveoli and carry more dangerous substances
Ultrafine particles are small enough to reach deep lung air sacs (alveoli) and tend to carry more metals and peroxide compounds that can drive oxidative damage. Learn more.
They only affect the stomach lining after you swallow them

9 Which of these is not one of the “Four E’s” said to drive chronic inflammation?

Excess linoleic acid (LA)
Electromagnetic fields (EMFs)
Endocrine-disrupting chemicals (EDCs)
