Are Pistachios Healthy? Here's What Experts Say
Pistachios are packed with vitamins, minerals and nutrients, including beta carotene, phosphorus, vitamin B6, thiamine, potassium, magnesium and fiber. Compared to other nuts, they are also high in carotenoids, a type of antioxidant that helps reduce the risk of chronic disease and improves heart health.You can also eat a lot of them in just one serving, which is one ounce, or 49 pistachios.Both raw and roasted pistachios contain a lot of fat: about 13 grams, which is 17% of the recommended daily total. But most of it is monounsaturated fat, a heart-healthy type that can help lower levels of bad cholesterol. Pistachios are also a good source of protein; a serving contains about 6 grams.“All nuts are healthy because they are a great source of plant-based protein, fiber, and healthy monounsaturated and polyunsaturated fat, nuts and seeds of all varieties can improve health.”But pistachios, more than other nuts, may also help reduce blood pressure, That’s due to their monounsaturated fatty acids, their phytosterols (plant compounds in the nut that can help lower cholesterol) and their high fiber.“They also contain lutein, beta-carotene, and tocopherols, which can reduce systemic inflammation... pistachios may act as a prebiotic, or food for your gut bacteria.

A top Cornell food researcher has had 13 studies retracted. That’s a lot. - Vox
Stopping an experiment when a p-value of .05 is achieved is an example of p-hacking. But there are other ways to do it — like collecting data on a large number of outcomes but only reporting the outcomes that achieve statistical significance. By running many analyses, you’re bound to find something significant just by chance alone.

According to BuzzFeed’s Lee, who obtained Wansink’s emails, instead of testing a hypothesis and reporting on whatever findings he came to, Wansink often encouraged his underlings to crunch data in ways that would yield more interesting or desirable results.

In effect, he was running a p-hacking operation — or as one researcher, Stanford’s Kristin Sainani, told BuzzFeed, “p-hacking on steroids.”

Wansink’s sloppiness and exaggerations may be greater than ordinary. But many, many researchers have admitted to engaging in some form of p-hacking in their careers.

A 2012 survey of 2,000 psychologists found p-hacking tactics were commonplace. Fifty percent admitted to only reporting studies that panned out (ignoring data that was inconclusive). Around 20 percent admitted to stopping data collection after they got the result they were hoping for. Most of the respondents thought their actions were defensible. Many thought p-hacking was a way to find the real signal in all the noise.

Sugary Drinks, but Not Foods, Linked to Increased Mortality
Read into this with caution. This is a single study, although large scale and longitudinal. No cause & effect have been found; although there are hypotheses offered they are just that -- guesses as to what's going on. They do note that previous studies that found that all sugar consumption raise mortality risk, this is the first to look separately at food and drink.

While the increased risk of mortality itself is higher for those who are overweight or obese, there is no additional risk for CVD by weight.

Is Cholesterol Killing Us? A Beginner's Guide to Cholesterol | Nerd Fitness
While dietary fat, AKA Dr. Evil, has no doubt been stigmatized as the truly evil madman that is ruining our health, Mini-Me (AKA “cholesterol”) has been branded as the evil sidekick, almost as equally responsible for destroying our bodies.
