Is the cholesterol hypothesis dead?

Is there any life left in the cholesterol hypothesis (a.k.a. the lipid hypothesis)? Is there anything left for serious scientists to cling to or is time for its mouldering corpse to end up on the trash heap of medical history, alongside lobotomy, bloodletting and the theory of the four humors? I was asked this question by a reader of this blog recently, and as it happens, a systematic review was recently published in Evidence Based Medicine (my favorite medical journal, mainly because it is edited by the brilliant Dr. Carl Heneghan) that definitively answers this question, so I thought it would be interesting to go through what the evidence says together. read more

Covid-19 interview with Ben, Rob, and Robbo

A few days back I did an interview on the Ben, Rob and Robbo show about covid-19. In the interview we discuss what measures were taken in Sweden to prevent the spread of the disease, whether Sweden has now developed herd immunity, and what the role of T-cells vs antibodies is if that is the case. We also discuss whether the Swedish government intentionally “sacrificed” a couple thousand citizens for the “greater good”, and how Sweden’s response compares to its neighbors. Finally, we talk about how long it makes sense to stay in lockdown and whether other countries should stay in lockdown until a vaccine is available or whether it makes more sense to copy the Swedish herd immunity strategy. The complete interview can be found here. read more
