Reliable Medical Information & Research Resources

There is an enormous amount of medical information online, but not all of it is reliable. These websites are useful starting points for understanding health conditions, treatments, and medical research.

Major medical institutions provide valuable information about established treatments and current guidelines. However, guidelines may lag behind emerging research, and knowledgeable researchers sometimes disagree about how evidence should be interpreted.  This is particularly evident in metabolic health and low-carb diets 

Health Curious encourages readers to examine the evidence, consider different perspectives, and recognize uncertainty rather than assume any single organization has all the answers.

Understanding Medical Conditions

MedlinePlus — U.S. National Library of Medicine

A free resource from the National Institutes of Health offering understandable explanations of diseases, medications, medical tests, and treatments. Particularly helpful when encountering unfamiliar medical terminology.

NHS Health A–Z — United Kingdom

The UK's National Health Service provides straightforward information about symptoms, diagnoses, treatments, and prevention. It can be useful to compare British and American medical guidance.

Some NHS recommendations, including those concerning vitamin D supplementation, are more conservative than those advocated by certain researchers and clinicians. This illustrates why consulting more than one source can be worthwhile.

Medical Centers and Current Treatments

Mayo Clinic

Clear explanations of medical conditions, diagnostic tests, and established treatment options. A useful starting point for understanding conventional medical care.

Cleveland Clinic

An extensive collection of patient-friendly articles covering medical conditions, treatments, medications, and healthy living.

Clinical Trials and Emerging Research

ClinicalTrials.gov

A database of clinical studies conducted in the United States and around the world. Particularly useful for investigating experimental treatments, uncommon conditions, and research that has not yet become standard medical practice.

A trial listed here does not necessarily mean a treatment has been shown to work. Some studies are recruiting participants, others are underway, and some have published results.

Alternative Perspectives & Emerging Research

Some organizations focus on areas where medical practice is evolving or where researchers challenge conventional recommendations. These resources can offer valuable perspectives, although their claims should be examined as critically as those of established medical institutions.

Society of Metabolic Health Practitioners (SMHP)

A nonprofit organization promoting metabolic health through education, research, and clinical guidance, with particular emphasis on therapeutic carbohydrate reduction. Its website includes research resources, clinical guidelines, and a directory of practitioners who use low-carbohydrate approaches to metabolic health. See also Insulin Resistance. 

Metabolic Mind

Explores the potential of ketogenic and other metabolic therapies for mental and neurological conditions. Includes research discussions, interviews, videos, and educational resources. Some of these approaches remain experimental. See also Brain Health.

Public Health Collaboration — United Kingdom

An organization advocating improvements in public health through nutrition and lifestyle changes, particularly reducing refined carbohydrates and improving metabolic health.

GrassrootsHealth

A nonprofit public health research and education organization with a particular interest in vitamin D. It emphasizes testing and individualized vitamin D levels and advocates targets that may be higher than those recommended by major public health organizations. Evidence for benefits from higher levels remains debated.

How I Evaluate Medical Information

When researching a medical question, I try to distinguish among:

• Well-established findings supported by multiple high-quality studies.

• Promising but preliminary research that may eventually change medical practice.

• Disputed recommendations where experts interpret the evidence differently.

• Personal experiences and testimonials, which can raise interesting questions but cannot establish whether a treatment works.

Randomized controlled trials are especially useful, but they are not always available, practical, or sufficient to answer every medical question. Observational research, biological mechanisms, and clinical experience can also contribute useful information, provided their limitations are recognized.

The goal is not to accept or reject conventional medicine, but to understand what the evidence actually shows—and what remains uncertain.
