Fatty acids and dietary fat


All fats are combinations of fatty acids. Nutritionists characterize a dietary fat or oil as saturated, monounsaturated, or polyunsaturated depending on which fatty acids make up the largest portion of the fat or oil:

Foods such as butter, which are high in saturated fatty acids, are solid at room temperature and get harder when chilled.

Foods such as olive oil, which are high in monounsaturated fatty acids, are liquid at room temperature; they get thicker when chilled.

Foods such as corn oil, which are high in polyunsaturated fatty acids, are liquid at room temperature and stay liquid when chilled.

So how come margarine, which is composed primarily of unsaturated fatty acids, is solid? Because its fatty acids have been artificially saturated with extra hydrogen atoms. This process, called hydrogenation, turns an oil, such as corn oil, into a solid fat — margarine.

Hydrogenated fats are sometimes called trans fatty acids, but no matter what you call them, these fatty acids raise — rather than lower — cholesterol levels. As a result, these days most margarines boast “no trans fats” right on the label. I know your mother told you not to toot your own horn, but these guys have earned the right. So when you’re shopping, pick them.

  6. Today, I went to the beach front with my children.
    I found a sea shell and gave it to my 4 year old daughter and said
    "You can hear the ocean if you put this to your ear."
    She placed the shell to her ear and screamed.

    There was a hermit crab inside and it pinched her ear.
    She never wants to go back! LoL I know this is
    totally off topic but I had to tell someone!

  9. Everything published made a lot of sense.
    But, consider this, what if you typed a catchier title?

    I mean, I don't want to tell you how to run your blog, however what if you added something to maybe get a person's
    attention? I mean "Fatty acids and dietary fat" is kinda vanilla.

    You might peek at Yahoo's home page and watch how they write post titles to get viewers to click. You might try adding a video or a related pic or two to get people excited about what you've written.

    In my opinion, it could make your website a little livelier.
