This story helps temper some of the rampant health claims made for vitamin D with information about the nature of the studies giving rise to the enthusiasm. It is a step in the right direction for helping readers discern between health claims supported by actual clinical trials and those seen in observational studies.
People are bombarded with health claims and learning to question their basis – how strong is the evidence supporting the claim – is helpful for people so that they can make more informed decisions.
The cost of testing for vitamin D levels was provided. No information about the costs of vitamin D supplements, but we’ll give the story the benefit of the doubt on this one.
The story did not contain any quantification of the potential benefits from vitamin D. On the one hand, the story mentioned about 12 conditions that might be helped. On the other hand, JoAnn Manson basically said we don’t really know where the true benefits will be until after the clinical trial is done. That was an appropriate balance or the story.
While Dr. Holick is quoted in this story as commenting that "…there is no downside to increasing your vitamin D intake", he is also a co-author on a 1992 paper in the New England Journal of Medicine documenting a series of deaths due to accidental overdose of vitamin D. The story did not give any weight to the potential for problems with over-consumption of vitamin D.
.
The story first presented the assertions of Dr. Holick that vitamin D supplementation had the capacity to prevent a wide range of conditions without substantiating his claim. This was followed by a more balanced explanation about the limitations of observational studies which have yielded the suggestions about the possible multifaceted roles for vitamin D in maintaining health.
The story did not engage in overt disease mongering. Even the suggestion that conditions from Alzheimers’ to autism down to tuberculosis could be avoided with vitamin D supplementation was countered by another perspective.
Several respected experts in the field of vitamin D research and the epidemiology of disease were quoted for this story.
The story mentioned a variety of sources for obtaining vitamin D.
The story did mention various means to increase one’s level of vitamin D including supplements, fortified foods, and exposure to sunlight. It would have been useful to mention that vitamin D is commonly found in multivitamins, and many calcium supplements contain vitamin D as well.
The new 5-year NIH study on Vitamin D was emphasized.
Does not appear to rely on a press release.
Systematic, Criteria-Driven
Like Michael Corleone of science reporting that @garyschwitzer is (he tries to get out, bullshit disguised as #science #journalism keeps pulling him back in!), he drops this on @nytimes idiocy 🙄 in reporting T1 diabetes "cure"

A great read on this weekend’s NYT claims of a cure for Type 1.
Cure for Type 1 diabetes? We’ve been down this road before with NY Times https://www.healthnewsreview.org/2021/11/cure-for-type-1-diabetes-weve-been-down-this-road-before-with-ny-times/
"But it is the framing and the emphasis of the #journalism by a leading science journalist at a leading newspaper that demands scrutiny. It has an impact on readers and on sick people that may cause harm by promoting false hope about extremely preliminary research"
👍👏💪 truth https://twitter.com/garyschwitzer/status/1465399358137024518
