Vital Stem: Affordable Stem Cell Treatments for Everyone? Anti-Aging Breakthrough?
Vital Stem is a dietary supplement mixture that supposedly reverses the changes of normal aging by increasing the body’s production of stem cells. We can’t know if it works, because it hasn’t been tested. Is Vital Stem a Miracle Anti-Aging Remedy? Evidence is lacking.

Treating Chronic Fatigue Syndrome with Cognitive Behavioral Therapy and Graded Exercise Therapy: How the PACE Trial Got It Wrong
The PACE trial said graded exercise is an effective treatment for CFS. CFS patients disagree. Chronic fatigue syndrome (CFS), also known as myalgic encephalomyelitis (ME), and the recently-suggested IOM term systemic exertion intolerance disease (SEID), is characterized by long-term fatigue and a host of other symptoms that impair the patient’s ability to… read more "Treating Chronic Fatigue Syndrome with Cognitive Behavioral Therapy and Graded Exercise Therapy: How the PACE Trial Got It Wrong"
Stem Cells for Macular Degeneration: Meticulous Science vs. Unethical Carelessness
Age-related macular degeneration (AMD) is a major cause of vision loss in people over 50. Thirty percent of us will develop it by age 75-85. There is no cure.

Dietary Associations with Cardiovascular and Diabetic Mortality: “Bacon, soda, and too few nuts”?
A recent study attempted to quantify the association of ten dietary factors with deaths from cardiovascular disease and diabetes. Headlines about the study were misleading. How likely is bacon to kill you?

New evidence clarifies its modest benefits and worrisome risks. Lots of men are taking testosterone supplements, some of them for good reasons and some for not-so-good reasons.… read more "Update on Testosterone Supplementation"
Magnets Provide Amusement, But Not Health Benefits
Over the years, the claims for health benefits of magnets have provided me with much amusement. Here are just a few examples: A skeptic pointed out that if magnets in health products really attracted red blood cells as claimed, an MRI scan with magnets many orders of magnitude stronger would… read more "Magnets Provide Amusement, But Not Health Benefits"
Why Do Things That Are Unlikely to Harm Us Get the Most Attention?
We are very bad at assessing risk, often giving the most attention to the things that are least likely to harm us. Geoffrey Kabat’s new book teaches us how to think more clearly about scientific studies of environmental health risks. Sharks get a lot of bad press and inspire a… read more "Why Do Things That Are Unlikely to Harm Us Get the Most Attention?"
Natural Remedies for Diabetes: Plavinol, Glucopure
There is not enough evidence to support using dietary supplements in the treatment of diabetes. There is preliminary evidence that some herbs lower blood sugar by a modest amount, but it would be foolish to think they could replace conventional treatment of diabetes. There is good news for diabetics; unfortunately,… read more "Natural Remedies for Diabetes: Plavinol, Glucopure"
