EB - I don't want to be accused of taking yet another thread
I will simply respond that what you quote above are statements NOT proven facts... just because someone or some body says something does not make it a scientific fact - even if that person is a scientist.
We have all been told by the media (every other day) the food industry (eat all the low-fat [high HFCS] yogurt you like... it's good for you!), health establishment, government agencies, XYZ diabetes associations etc... that low-fat is bad for us. This hypothesis has been around for at least 30 years that "eating fat makes us fat and gives us heart disease"; so you would think it would be easy to find some actual scientific research where this has been proven. I, and others here on DF have already posted many sources which show that fat is not bad for you and indeed I (like Joel above) have dramatically improved my lipids by eating MORE fat
Look at the facts I posted above for the USDA regarding a steak... doesn't that give you any pause for thought as to whether the current message makes any sense? It did me. If you actually went to the USDA site you would see that not only does a steak contain the so-called "good fats" but it is also rich in vitamins and minerals
...and here was me thinking that it was the job of the younger generation to question things, and shake up old assumptions
in the words of Jacob Bronowski, "It is important that students bring a certain ragamuffin, barefoot irreverence to their studies; they are not here to worship what is known, but to question it. "
