Dark roast coffee and cinnamon may support brain health, but milk and sugar effects lack strong human validation.

Rep speed doesn't significantly affect muscle growth when training close to failure, but super-slow protocols may reduce gains.

Controlled human trials show no adverse health effects from artificial sweeteners at typical intake levels when used to replace sugar.

Food source quality matters more than low-fat or low-carb labels for heart health, according to observational studies.

Dietary fat does not suppress cortisol via HPA feedback; glucose increases it, while fat shows no effect compared to water.

Higher volume may slightly increase muscle growth, but deloading shows no benefit at low volumes; individual responses vary widely.

Total protein, creatine, training volume, and proximity to failure drive muscle growth; equipment type and timing matter less than consensus science shows.

Vitamin D may support muscle growth in older adults and alter metabolic signals in mice, but human evidence for fat loss or steroid-like effects is lacking.

Reducing sodium and increasing potassium intake lowers blood pressure, stroke, and death risk without harm at low levels, according to robust clinical evidence.

Some food additives show biological effects in studies, but human evidence is limited and inconsistent.

B12 deficiency is linked to premature graying in some cases, but reversal is rare and other factors like genetics and other nutrient deficiencies play major roles.

Testosterone replacement at normal levels does not increase heart disease or prostate cancer risk, but requires monitoring for blood thickening and lipid changes.
