Scientists have cured mice of Type 1 with gene therapy. Apparently it will work for Type 2 as well, though a lot of that is caused by following terrible nutrition advice.
Most Americans don’t think they should be able to be purchased with food stamps.
I agree. I oppose food stamps (it’s a federal subsidy to farmers), but if you’re going to give them out, they should only be used for food.
Problems with p-hacking are by no means exclusive to Wansink. Many scientists receive only cursory training in statistics, and even that training is sometimes dubious. This is disconcerting, because statistics provide the backbone of pretty much any research looking at humans, as well as a lot of research that doesn’t. If a researcher is trying to tell whether changing something (like the story someone reads in a psychology experiment, or the drug someone takes in a pharmaceutical trial) causes different outcomes, they need statistics. If they want to detect a difference between groups, they need statistics. And if they want to tease out whether one thing could cause another, they need statistics.
The replication crisis in psychology has been drawing attention to this and other problems in the field. But problems with statistics extends far beyond just psychology, and the conversation about open science hasn’t reached everyone yet. Nicholas Brown, one of the researchers scrutinizing Wansink’s research output, told Ars that “people who work in fields that are kind of on the periphery of social psychology, like sports psychology, business studies, consumer psychology… have told me that most of their colleagues aren’t even aware there’s a problem yet.”
I think the hockey stick episode shows that this is a problem with climate research as well.
The point of peer review has always been for fellow scientists to judge whether a paper is of reasonable quality; reviewers aren’t expected to perform an independent analysis of the data.
“Historically, we have not asked peer reviewers to check the statistics,” Brown says. “Perhaps if they were [expected to], they’d be asking for the data set more often.” In fact, without open data—something that’s historically been hit-or-miss—it would be impossible for peer reviewers to validate any numbers.
Peer review is often taken to be a seal of approval on research, but it’s actually more like a small or large quality boost, depending on the reviewers and scientific journal in question. “In general, it still has a good influence on the quality of the literature,” van der Zee said to Ars. But “it’s a wildly human process, and it is extremely capricious,” Heathers points out.
There’s also the question of what’s actually feasible for people. Peer review is unpaid work, Kirschner emphasizes, usually done by researchers on top of their existing heavy workloads, often outside of work hours. That often makes devoting the time and effort needed to catch dodgy statistics impossible. But Heathers and van der Zee both point to a possible generational difference: with better tools and a new wave of scientists who aren’t being asked to change long-held habits, better peer reviews could conceivably start to emerge. Although if change is going to happen, it’s going to be slow; as Heathers points out, “academia can be glacial.”
“Peer review” is worse than useless at this point, I think. And it’s often wielded as a cudgel against dissidents of the climate religion.
Why it’s “almost useless and misleading.”
No, actually, it’s worse than useless.
The reign of terror is almost over. What’s not mentioned, though, is that even if the kids were eating the food, it’s not healthy for them. Low grains are only a little less terrible than refined ones, and low fat constitutes physical child abuse, because they need fat to grow their brains.
This mouse study seems very promising, but there is a word missing here:
In consideration of the challenges and side effects associated with prolonged fasting in humans, we developed a low-calorie, low-protein and low-carbohydrate but high-fat 4-day fasting mimicking diet (FMD) that causes changes in the levels of specific growth factors, glucose, and ketone bodies similar to those caused by water-only fasting (Brandhorst et al., 2015) (see also Figure S1 for metabolic cage studies). Here, we examine whether cycles of the FMD are able to promote the generation of insulin-producing β cells and investigate the mechanisms responsible for these effects.
It’s called “ketogenic,” people. Kee Toe Jen Ick. Low carb, high fat.
…as a metabolic disease. A long but interesting essay.
At least the community is starting to wake up to the hazards of sugar. I’ve seen a proposal to make food stamps ineligible for items containing it. Makes sense to me. It could help a lot with the obesity epidemic.

Health authorities continue to fail us:
Considering the above, no one in their right mind would take any kind of dietary advice provided by the authorities at face value. It’s little wonder then that so many are taking matters into their own hands. Thirty years ago, if the USDA, AHA, or AMA told you something was bad for you, you stopped eating it. You didn’t question, because they were the ones with credibility and years of study. It was simply too much trouble for the average person to find the information they needed. Thankfully with the internet, all of the information needed is now available to anyone who wants it. We no longer have to put blind trust in authority figures because we can sift through the information ourselves and ask the right questions. If anything, the glut of information shows that the public’s trust in nutrition advice given by the authorities and media was sorely misplaced.
Same thing with climate, for the same reasons: there’s a lot of public policy, and money, at stake.
We don’t know much more about it than we do.
