Mike Zimmer’s first Vikings mini-camp has even veterans nervous

Filed under: Football — Tags: , , , — Nicholas @ 09:37

As a brand-new head coach, Mike Zimmer is allowed to have a few more early team practices and training sessions than established coaches under the NFL’s bargaining agreement. The first mini-camp was held this week, from Tuesday to Thursday, and even the veteran players were approaching it like the first day on the job:

Matt Cassel has been around the NFL block a few times in his 10 seasons as a quarterback. Not much surprises him anymore, and yet he found himself unable to sleep the night before the Vikings minicamp this week.

“I was excited, jittery,” he said.

Chad Greenway felt those same butterflies. The veteran linebacker compared it to being a rookie or college freshman again.

“It was straight-up nerves,” he said.

Captain Munnerlyn arrived in town as a key offseason acquisition who’s supposed to help fix a shipwrecked defense, and even he felt a weird uneasiness.

“With a new coach, it’s a clean slate for everybody,” he said. “That means every position is open. Except for the running back position.”

Good call. We’ll go out on a limb and suggest that Adrian Peterson probably didn’t need to impress the new coaching staff in order to keep his job. But everyone else convened at Winter Park this week with an overarching sense of anxiety not normally evident at a routine offseason workout.

Imagine your first day with a new boss, one who’s known for his no-nonsense personality and brutal honesty. And salty language.

“You’re on edge and trying to make a good first impression,” Greenway said. “You know the draft is coming in a week. They’ll probably make some decisions based off of this camp.”

If Mike Zimmer’s first on-field introduction made players nervous and uncomfortable, that’s a good thing. This organization had become too lethargic under the previous regime. The atmosphere at Winter Park became stale as losses piled up last season.

Fat’s negative health impact reconsidered

Filed under: Food, Health, Science — Tags: , , , — Nicholas @ 09:19

Hmm. Today seems to be health news day. In the Wall Street Journal, Nina Teicholz looks at the dubious science behind the saturated fat demonization we’ve all seen in so many health stories:

“Saturated fat does not cause heart disease” — or so concluded a big study published in March in the journal Annals of Internal Medicine. How could this be? The very cornerstone of dietary advice for generations has been that the saturated fats in butter, cheese and red meat should be avoided because they clog our arteries. For many diet-conscious Americans, it is simply second nature to opt for chicken over sirloin, canola oil over butter.

The new study’s conclusion shouldn’t surprise anyone familiar with modern nutritional science, however. The fact is, there has never been solid evidence for the idea that these fats cause disease. We only believe this to be the case because nutrition policy has been derailed over the past half-century by a mixture of personal ambition, bad science, politics and bias.

Our distrust of saturated fat can be traced back to the 1950s, to a man named Ancel Benjamin Keys, a scientist at the University of Minnesota. Dr. Keys was formidably persuasive and, through sheer force of will, rose to the top of the nutrition world — even gracing the cover of Time magazine — for relentlessly championing the idea that saturated fats raise cholesterol and, as a result, cause heart attacks.

[…]

Critics have pointed out that Dr. Keys violated several basic scientific norms in his study. For one, he didn’t choose countries randomly but instead selected only those likely to prove his beliefs, including Yugoslavia, Finland and Italy. Excluded were France, land of the famously healthy omelet eater, as well as other countries where people consumed a lot of fat yet didn’t suffer from high rates of heart disease, such as Switzerland, Sweden and West Germany. The study’s star subjects — upon whom much of our current understanding of the Mediterranean diet is based — were peasants from Crete, islanders who tilled their fields well into old age and who appeared to eat very little meat or cheese.

As it turns out, Dr. Keys visited Crete during an unrepresentative period of extreme hardship after World War II. Furthermore, he made the mistake of measuring the islanders’ diet partly during Lent, when they were forgoing meat and cheese. Dr. Keys therefore undercounted their consumption of saturated fat. Also, due to problems with the surveys, he ended up relying on data from just a few dozen men — far from the representative sample of 655 that he had initially selected. These flaws weren’t revealed until much later, in a 2002 paper by scientists investigating the work on Crete — but by then, the misimpression left by his erroneous data had become international dogma.

Take every salt report with a pinch of salt

Salt is bad for you, as we’ve been told for years and years. It raises your blood pressure and makes you more prone to strokes and other nasty health issues. Except … perhaps not:

The more salt we eat, the more water our body retains. This increases blood pressure, at least until our kidneys flush out the salt and water. Those who see salt as a problem believe that the effect on blood pressure is more lasting, and that if too much salt is ingested over a long period of time it will cause hypertension and perhaps death. A much-cited study carried out by America’s National Institutes of Health in 2001, called the DASH-sodium study, found that participants put on diets that were lower in sodium than the control group ended up with significantly lower blood pressure. This study forms the basis for many of the public-health pronouncements that demonise salt. America’s dietary guidelines, based on “a strong body of evidence”, put salt at the top of the list of things to avoid.

The body of evidence, though, is rather weaker than the American government lets on. The DASH study is one of many that have looked at the effects of salt intake on health. Others have failed to produce similar results. The English study mentioned above finds a correlation, but other factors — such as a simultaneous decline in smoking — seem more likely to account for the improved health outcomes. In 2011 two meta-analyses, which look at the results from many different studies, were published by the Cochrane Collaboration, a non-profit that reviews medical evidence. The first found that reducing salt intake leads to lower blood pressure, but concluded that there is “insufficient evidence” that this will lead to fewer premature deaths or a lower incidence of heart disease. The second concluded, rather simply, that “we do not know if low salt diets improve or worsen health outcomes.” The authors went on to say that “after more than 150 [randomised controlled trials] and 13 population studies without an obvious signal in favour of sodium reduction, another position could be to accept that such a signal may not exist.”

Some researchers go a step further, claiming that reducing salt intake actually increases a person’s risk of dying. The body needs some amount of sodium; if it gets too little the kidney secretes an enzyme called renin that can lead to hypertension. Some studies have found that low sodium levels were associated with increased risk of heart failure. Others suggest that a low sodium-to-potassium ratio may be the key to heart health. Much depends on the individual. The evidence is inconclusive, yet public-health officials have long presented the link between salt and heart disease as if it were fact. Such confidence is not warranted. There are plenty of reasons to avoid a full English breakfast, but salt may not be one of them.

I am not a number!

We had a call from Rogers (our ISP/cable provider) last night to discuss our current internet plan (we’ve been bumping up against our data cap lately, even though we increased it from 60GB to 80GB only a few months ago). I pointed out that my son’s internet bill while he was away at university came to about the same as our bill with Rogers, but that his data cap was 250GB. I asked if Rogers could come close to offering me that in Brooklin, since Cogeco is clearly able to turn a profit while offering folks in Peterborough a much higher data cap.

Rogers couldn’t quite match the offer, but for a slightly higher monthly bill we’ll now have a 270GB cap and higher (nominal) upload/download speeds. After this, I got an email that showed I’m not just a number to Rogers … I’m {$/process_data/xmlData/CRCFormatRequest/CustomerInfo/FullName$} instead:

QotD: The educational machinery that produces the modern twenty-something

Filed under: Bureaucracy, Business, Education, Quotations — Tags: , — Nicholas @ 00:01

When conservatives complain that children are not being taught anything in public schools, they’re half right: They’re not being taught anything useful. They’re taught how to conform. That’s really the point of so many of the stupid rules in modern schooling, people learn to obey the irrational.

This translates into the corporate world in two ways. Those leaving the educational system are outwardly rebellious and undisciplined, even slovenly. Inwardly they’re perfect conformists. They haven’t the slightest notion of principles or integrity, it’s been beaten out of them by the public schools. They are desperate to fit in and conform in a way that is common among teenagers, but used to fade away as people entered their twenties and thirties. As a cranky old executive once observed to me, the young people aren’t so much soft as weak. Passionate about trivia and indifferent toward the fundamentals of life and work.
