  • The Food and Drug Administration recently announced companies will be required to remove

  • trans fats from their foods over the next few years. But, like, what is a trans fat?

  • Trans fat gets a lot of bad press, but that's because fat is a tough cookie; some are good

  • for you, some are bad for you. Fat isn't just FAT there's a lot of different KINDS of fat.

  • Each type manifests differently, and… #WHEW it's complicated.

  • Fats coat membranes. They store energy, they protect vital organs and they insulate tissues. The word

  • "lipid" is a general term for a group of hydrocarbons -- that is to say a string of carbon atoms

  • surrounded by hydrogen atoms -- which includes all fats and many other basic molecules in body.

  • the body. Triglycerides, cholesterols, and Vitamins like A,D,E, and K are all lipids[1].

  • Different fat sources each form chains a little differently; and those arrangements change

  • how your body can process them.

  • The three main lipids you hear about in the food world are saturated fats, unsaturated

  • fats and trans fats. Picture a parking lot, if the hydrogen atoms are the cars -- saturated

  • fats are saturated -- or FILLED with hydrogen -- all the spots are full. Unsaturated fats

  • have some spaces here or there --and the shape of the molecules will determine their behavior -- like some of spots are empty.[2][3].

  • Saturated fats are solid at room temperature because the filled up molecules are more rigid;

  • they usually come from animals, but are also found in coconut oil and palm oil. Whereas

  • unsaturated fats have more room for hydrogen, which allows the molecules to bend, fold over.

  • This folding allows them to stay liquid at room temperatures -- so you can think of them as oils[4]!

  • These mostly come from plants, and are sometimes just called vegetable oils. So the olive oil, corn

  • oil, and peanut oil are all unsaturated fats.

  • Mono-unsaturated fats are called "good" fats[5]. They're much easier to produce so companies

  • came up with a way to convert these liquid lipids to solids in a process called HYDROGENATION.

  • Hydrogenated oils have been chemically altered to move the hydrogen around and fill up more

  • of the empty parking spaces in the chain. They try to make cheaper plant fats look more

  • like expensive animal fats; think margarine or shortening[6]. Because they have to alter

  • the hydrogen bonds, these hydrogenated oils, are ALSO known as TRANS FATS[7].

  • Up until the early 1980s, saturated animal fats, like beef tallow, were used to make delicious delicious french

  • fries, until it was thought saturated fats could raise levels of bad or Low-density lipoprotein

  • cholesterol -- essentially causing increased risk of heart disease. The public was alarmed, so companies

  • switched to *partially hydrogenated vegetable oil.* Recently, studies like one in the Annals

  • of Internal Medicine from last year[8] -- show that saturated fat is not nearly the demon

  • it was made out to be and might be entirely neutral in our diet, but that TRANS FAT is just TERRIBLE. It is the worst: causing

  • increases in LDL cholesterol and decreases in High-density lipoprotein -- or good cholesterol[9][10].

  • In fact, studies have found diets high in trans fats correlate with memory loss, heart

  • disease, and of course weight gain obesity[11].

  • Overall the FDA ban might be a little late to the party. From 2003 to 2012 the amount

  • of trans fats consumed has dropped 78 percent, mainly due to food label, but it's better

  • late than never. Commonly, you hear people say, "Everything in moderation," which works

  • for saturated and unsaturated fats, but for trans fat? No way.None. The CDC says to keep "trans

  • fatty acid consumption as low as possible[12]!" That's HUGE!

  • What's your favorite type of good fat? Avocados? Nuts? Olive oil????? I LUVVV olive oil. It's the best..
