Like most allied health professions, RDs report not having had enough training in evidence-based practice (and most want more training). Lots of room for uplifting EBP, starting with crdns and krdns (which drive national examinations)! See Table 1: pubmed.ncbi.nlm.nih.gov/3815…
Cosign for dietetics. It's gotten out of control in the field - more enthusiasm for flipping evidence-based practice on its head to feel like a naturopathic prescriber with supplements than there is for rigor & excellence in dietetics.

We need evidence-based ā€˜research’, where high quality, original, up to date systematic reviews and guidelines identify the gaps, and drive much needed clinical nutrition trials. And the trials need to measure outcomes that matter to patients and the public
It is bizarre living in the Bay Area, being around folks so interested in nutrition/biohacking, yet I go to work daily knowing that there is about zero local supported infrastructure left to run a clinical trial on nutrition/supplements/general non-pharmaceutical interventions

As corresponding author, I agree about fallacies of low fat, low carb. Using such a lens allows for diet categorization, but grossly oversimplifies. The NMA of 14 diets shows best was Mediet (& lifestyle), which is not very restrictive. Needed: RCTs on whole food vs X vs Y diet
Diets focusing on restricting a particular macronutrient (i.e. low fat, low carbohydrate) largely perform the same at weight loss, blood pressure reduction. Until the evidence around benefits of different eating patterns is strengthened, we should instead focus on the core dimensions common among them: ā¬†ļø Non-starchy vegetables šŸ„• , whole fruitsšŸ“ , legumes🫘 , whole grains🄣 , nuts🄜 , seeds🌻 , low-fat dairy products šŸ„› ā¬‡ļø meatsšŸ– , sugar-sweetened beverages🄤 , refined grains🄐 , ultra-processed foodsšŸŸ šŸ” Need more guidance?

Agree, big problem. Publishing becoming monetized & p. review is these journals is often horrendous. Reason to understand & prioritize methods > results. 1st question in appraising methods, did authors follow detailed, published protocol & are any deviations explained & sensible
There are no longer any real barriers to publishing anything in science. You can find a paper to cite to support just about any view. People also believe that because it's published, it's true. High-volume, OA, pay-to-publish journals are slowly destroying science... 1/

A nuanced perspective. Who and what to believe? One complex answer: do your research, think more and discuss more
Replying to @wideawake_media
If the food system contributes to 30% of the emissions and all of livestock to 12%, then the majority comes from plants to begin with. But the entire anti-meat argument is simplistic - here's a video explaining why:

reflections covid19 vac @scienceupfirst i) absolute estimates slides 1 & 2 on risk of adverse CV events - good ii) why switch to relative effects slide 7 likelihood CV benefit? iii) are any citations systematic reviews? I hope you are right, room to improve evidence summary
There is still a lot of misinformation circulating on social media about a possible link between COVID-19 vaccination and heart conditions. We summarize the facts based on evidence here šŸ‘‡scienceupfirst.com/project/m… #ScienceUpFirst

A nice article illustrating debates btw EBP & PH experts, using covid & toxicology exs. Unfortunately it uses familiar false narrative pitting RCT against non-RCT evidence! EBP practitioners embrace all evidence to aid transparent, fully informed decisions

Nice to start the year off with a paper acceptance! Congrats to @NirjharRuth & @methodsnerd for leading this systematic review of EBP competencies amongst dietetic professionals/trainees. Need 4 more research & curricula development #RDchat @jnutritionorg jn.nutrition.org/article/S00…
