Does cooking destroy nutrients, or sometimes make them easier to absorb? Human experiments, food chemistry and practical comparisons of heat, oils, vegetables and safety.
In 1994, Dr. Jonathan Shay, a renowned psychiatrist, brought forth an exceptional work that helped redefine our…
Most cracked heels come from dry thickened skin plus pressure, but diabetes, eczema, psoriasis and other conditions can contribute. Here is how to treat heel fissures safely and when to seek care.
Dry cupping creates suction on intact skin. It may temporarily change local sensation and blood flow, but evidence for meaningful pain relief is uncertain and detox or fat-removal claims are unsupported.
Seven common misconceptions about bipolar disorder, including mania, depression, long-term management and why ordinary mood changes are not the same as a psychiatric diagnosis.
There is no single symptom that proves carbohydrate intake is too low. Fatigue, constipation and poorer high-intensity performance can occur, but energy, fiber, electrolytes and adaptation matter too.
You can influence daily energy expenditure, but there is no safe switch that dramatically speeds up metabolism. Muscle, movement, protein intake and avoiding extreme dieting matter more than metabolism hacks.
Can a longer mental time horizon improve health or longevity? The evidence supports links with self-regulation, purpose and behavior, not cellular reprogramming.
Vitamin K1 and K2 have important biological functions, but many supplement claims go beyond the evidence. Correct serving-size data, AI values, vitamin K metabolism and warfarin safety.
NSAIDs can relieve pain and inflammation but carry real cardiovascular, gastrointestinal and kidney risks. Here is what FDA warnings mean, who should be cautious, and why acetaminophen is different.
Vitamin A has an unusual personality. Too little of it can damage vision, immunity and normal tissue…
Most vitamins and minerals do not need elaborate separation schedules. The interactions that matter most are a shorter list: calcium with iron, high-dose zinc with copper, biotin with lab tests, and vitamin K with warfarin.
Peter Attia is an interesting longevity figure for a reason that has little to do with any…
Liz Parrish’s gene-therapy self-experiment is scientifically interesting but uncontrolled. This article preserves the original longevity hypothesis while separating reported outcomes from independently validated evidence.
Creatine transport systems can increase short-term creatine retention, especially with carbohydrate or protein plus carbohydrate. But do they improve strength or muscle growth beyond creatine monohydrate?
Creatine is a strange success story in sports nutrition. It began as a molecule in basic muscle…
Is aspartame safe? IARC classified it as possibly carcinogenic, while JECFA kept the ADI at 40 mg/kg/day. Here is what that means for cancer risk, side effects and everyday use.
Boron is a trace element found in food. Small human studies have examined testosterone and bone-related markers, but evidence is insufficient to recommend routine boron supplementation for healthy men.
Healthy ear canals usually do not need internal cleaning. Learn when earwax needs treatment, why cotton swabs and ear candles can cause harm, and when a blocked ear is not wax.
UV exposure changes the volatile compounds released by living human skin. Human experiments measured acetaldehyde, propanal and ethene, supporting a lipid-oxidation mechanism behind “sun smell”.
