Stress can reduce cognition (memory, attention) by ~20% (with respect to test scores)

Certain botanicals (e.g., Rhodiola, Ashwagandha) may mitigate via HPA-axis regulation and neuroprotection

Evidence is promising but requires standardization. As always, act with diet, sleep, and exercise.

🤯🧬 In a stunning medical discovery, scientists have found a previously unknown organ hidden deep inside the human throat. This new organ, a pair of salivary glands located near the upper throat behind the nose, was detected accidentally while researchers were studying cancer patients using advanced imaging technology.

For centuries, anatomy textbooks listed only three major salivary gland pairs, the parotid, submandibular, and sublingual glands. The discovery of this hidden set, now referred to as the tubarial glands, adds an entirely new piece to our understanding of the human body. These glands are believed to play an important role in lubricating and protecting the upper throat and nasal passages.

The finding has huge medical implications. Knowing about the tubarial glands could help doctors avoid accidentally damaging them during treatments like radiation therapy for head and neck cancers. Protecting these glands may prevent complications such as chronic dry mouth and swallowing difficulties, improving patient recovery and quality of life.

This remarkable discovery proves that even in the 21st century, there are still secrets left in human anatomy. It reminds us that the human body is more complex and mysterious than previously thought, and that groundbreaking discoveries can still reshape science and medicine.

What other secrets do you think the human body is still hiding? Does this discovery surprise you?

Alcohol metabolism and why a few drinks linger longer than you think...

Your body processes >90% of ethanol in the liver, but the path creates toxic byproducts and drains key cofactors.

1️⃣ Step 1: Ethanol → Acetaldehyde
Alcohol dehydrogenase (ADH) converts ethanol to acetaldehyde, a far more toxic molecule.
💡 Example: Acetaldehyde is 10–30x more toxic than ethanol and drives hangovers.

2️⃣ Step 2: Acetaldehyde → Acetate
Aldehyde dehydrogenase (ALDH2) detoxifies acetaldehyde to acetate. Genetic variants slow this step, causing the flush response.
💡 Example: ~30–50% of East Asians have ALDH2 deficiency, leading to red flushing and higher cancer risk.

3️⃣ Step 3: Acetate → Acetyl-CoA
Acetate is converted into Acetyl-CoA for energy, but excess NADH shifts it into fat storage.
💡 Example: Chronic drinking promotes fatty liver because metabolism favors lipogenesis.

4️⃣ Cofactors Required
Both ADH and ALDH consume NAD⁺, creating a redox imbalance. Zinc is essential for ADH function, and glutathione helps mop up aldehyde damage.
💡 Example: Heavy drinking depletes NAD⁺ and glutathione, impairing energy metabolism and antioxidant defense.

5️⃣ Systemic Effects
Excess NADH raises lactic acid, blocks fat burning, and impairs gluconeogenesis. Acetaldehyde damages DNA and mitochondria.
💡 Example: This is why alcohol can cause both hypoglycemia and rapid fat gain.

6️⃣ What Can Help?
No hack accelerates clearance beyond ~1 drink/hour, but cofactors can reduce collateral damage:

Taurine supports acetaldehyde detox and membrane stability.
NAC restores glutathione.
B1, B3, B6 support alcohol dehydrogenase activity.
💡 Example: NAC + taurine supplementation has been shown to blunt acetaldehyde toxicity in experimental studies.

7️⃣ The Takeaway
Alcohol metabolism is an NAD⁺-draining, oxidative stress-driven process. You can’t outrun liver capacity, but you can support cofactors that protect cells.
💡 Example: Think of alcohol clearance like a one-lane road. You can’t make it faster, but you can repair the guardrails.

Your liver clears alcohol on its own schedule. Zinc, taurine, glutathione, and B-vitamins help reduce the metabolic fallout, but nothing cancels the 1-drink-per-hour rule.
