Comment Re:Fad diets based on new "science" (Score 1) 166

As others have pointed out, it is not that straightforward. I have a good friend who used to eat a high carbohydrate, low fat diet, as was the recommendation of dieticians at the time. She had to eat something every two hours or she would begin to get tunnel vision and other symptoms of low blood sugar. Then she changed her diet to one significantly higher in fat. By doing so, she was able to eliminate the need to eat so frequently. Several other minor health issues went away for her as well. This is just one example. Some people should eat a diet with a different balance of calorie sources than that which others should eat. The same is certainly true of fiber and other aspects of one's diet.

I think you are touching on the heart of the problem, but not stating it explicitly. The main reason that it is so hard to determine what the ideal diet is is that the answer is different for everyone.While there are groups of people whose dietary needs are close enough that they can follow the same basic nutritional plan, there are other groups of people for whom that basic nutritional plan is not healthy.

Of course, since then things have gotten worse...Actually, I would question your suggestion that a teaching position was a super sweet patronage position or that teachers did not actually do anything. Especially when you consider that Americans were in general better educated when tenure was introduced than they are today. The purpose of tenure was to reduce the level to which teachers were accountable to the people who pay their salaries (the voters). This allows teachers to focus more on indoctrinating children into progressive ideals (which the parents may not approve of) than on actually teaching them unimportant things like how to read or do basic math.
The basic theory of progressivism is that the "elites" (in other words, the bureaucrats) know better than everyone else how things should be done. The progressive solution to government corruption is to reduce the accountability of government workers to the voters. Tenure for teachers grows out of that the theory that a government worker who is unaccountable to anyone will be less corrupt than one who has to answer to an elected politician.
