For them, egg consumption should be personalised based on their lipid profile and overall diet.

Indeed, studies in humans have demonstrated that individuals could be hypo-responders or hyper-responders to dietary cholesterol.

Dietary cholesterol is found in animal foods, including meat, seafood, poultry, eggs, and dairy products. [...] Strong evidence shows that eating patterns that include less dietary cholesterol are associated with reduced risk of cardiovascular diseas...

There are enough issues with this study that it’s hard to make strong conclusions about whether eggs are healthy or not.

According to guidelines from the American Heart Association and American College of Cardiology, one to two eggs per day can fit into a heart-healthy diet, such as the Mediterranean diet, for people with normal cholesterol levels.

The fact is that eggs are a great source of high-quality protein and fat, which will keep you full for longer and may lead to lower consumption of unhealthy foods.

I think without a study like that, I’m not willing to make any conclusions about whether egg consumption is good or bad for you all.

The scientific reality is not in either of these extremes: eggs are still a food with very good protein quality, but at the same time, they have a high cholesterol and saturated fat content, which although not as harmful as once believed, are still a...

It always seemed entirely plausible to me that Covid escaped from a laboratory, but that doesn’t mean that it was deliberate or the result of nefarious activity.

This acknowledgement should not lead to the dismissal of the possibility (e.g., accidental leakage from a BSL-4 or lower biosafety level laboratory) or the legitimate concerns surrounding biosecurity and biosafety in general.

The story of lab leak in Wuhan is a fiction and it is as ridiculous as the counterclaim that Sars-CoV-2 comes from lab leaks in the US.

The problem is that argument doesn’t work — all evidence points to Covid starting around the same time the market outbreak started.

All he is saying in this Science article is that we need better, more comprehensive patient case and dated viral sequence data – at the time of first appearance of these viruses – to make this viral phylogenetic/evolutionary history approach more acc...

The data from the paper support the notion that Huanan market may have been just an amplifier of COVID-19 transmission, rather than the place where COVID-19 originated.

Much of the evidence used to shape the recommendations comes from epidemiological studies—large population surveys that look for associations between diet and disease. While these studies can generate hypotheses, they cannot prove cause and effect. T...

The evidence that cholesterol in one egg a day is safe for most people comes from huge studies — many conducted here at Harvard Medical School — that have followed hundreds of thousands of people over decades.

Bayesian reasoning serves as a bridge between quantitative and qualitative research that allows one to analyze any and all kinds of data within a single, unified inferential framework. This paper demonstrates the strength and flexibility of the Bayes...

The arguments around covid origins seem largely to fall into an inference trap Andrew has termed premature collapse of the wavefunction. Rather than maintaining multiple hypotheses with different levels of credibility, there seems to be a desire to c...

Determining the origin of an outbreak or pandemic can be divided into four stages: detection, identification, characterization, and attribution. Understanding how a specific pathogen entered and spread in a population to cause an outbreak is a multid...
