it's interesting to watch the saturated fat debunking come into mainstream media. Most people who are deep into food research (I don't like to say "nutrition" because it's such a loaded term now) reading many modern studies, books, and blog posts, already know that saturated fat is good and healthy. Both the comments here and on that article show a good deal of naysayers, and how powerful public opinion is.

These doubters seem to have the most basic "common knowledge" explanation of saturated fat: Sat.fat raises cholesterol, and cholesterol clogs your arteries, and clogged arteries lead to heart disease. If you think this chain is how your body works, you should know that it isn't nearly the entire story, and not accurate.

50% of every cell membrane in your body is saturated fat. Your body produces 75% of the cholesterol that it NEEDS to operate, the rest comes from diet. Why does your body produce cholesterol and what is its purpose? That would be a good research starting point if you are still anti sat.fat.

Of course, you shouldn't trust articles on science reporting. You shouldn't trust me. You should read studies and analyze them yourself. You might be pleasantly surprised by what you find.

There are probably thousands of articles on the topic.

I'd there any reason we shouldn't just accept the opinion of the FDA or AMA

The same reason you should not accept the TSA's opinion on security, or the FED's opinion on economics, or the DEA's opinion on marijuana, or the NSA's opinion on information security, or the SEC's opinion on market manipulation.

They are not working for you; while they try to avoid uprising, and that often does correlate with what is good for you - they generally care more about the profits/benefits to themselves/supporters/friends/industry.

Somehow, it is clear to almost everyone on this forum about the TSA and the DEA, to many (but not all) about the SEC - but almost everyone believes the FDA and FED are "the good guys". (The NSA switched sides from good to bad recently thanks to Snowden, I believe).

But there's no difference. Regulatory Capture has happened in all of these. Follow the money trail and the revolving door with the industry.

You just blew my mind. ;)

or the IPCC's opinion on global warming...

I haven't been following them recently, perhaps they are a little more dependable now - but in the late 80s they had reports saying a lot of coastal cities will be flooded by 2000 if we don't do anything. We didn't do anything. Nothing happened - but in 2008 I looked and those early reports mysteriously disappeared.

Yes, climate does change, for sure, and it's probably bad - but so many of the climate scientists were wrong in their predictions from 30 years ago, that they need to do more to be convincing with their predictions for 30 years from now. And the data crunching they are doing, every time I looked at it, is not convincing.

I agree with you - I hate the "the science is decided" or the "economics is decided" argument for any of the examples you mentioned. Whether it is saturated fat, sea level rise, or quantitative easing, one should maintain a healthy skepticism.

Should we listen to the government bodies and medical organizations that give us nutritional guidelines? This is a hard question to answer. I don't think anyone doubts that these bodies have good intentions and have our best interests at heart. But there is an obesity epidemic going on in America and spreading to the world, which has lead many people to question common nutritional teachings. Some people think we're just exercising less and eating more potato chips. However, those who are truly curious and go out hunting for information find evidence that contradicts the advice of these organizations.

We can see that slowly people are agreeing with the other side. They aren't doubting for no reason, evidence is coming from science and analysis of history. Really, you have to read studies. Science reporting is rarely accurate. Once you find the bad science that has lead to our current common knowledge nutrition, and how we got our current recommendations, you may doubt the advice of these organizations.

I am not saying don't trust them. They are working in the name of science for a good cause. But you have to be informed, and if your informing leads you to find doubting evidence (like it already has for me, some doctors, and many laypeople), then you can make your own decisions.
