In a perfect world, there’d be no commercially processed trans fats. But since that’s not the case…it’s up to you to ban them from your world.

The only way to do this is to carefully read the labels of all the processed foods you place in your grocery cart, and to be aware that commercially fried foods and many frozen foods contain trans fats (aka partially hydrogenated oil or trans fatty acids). If you can afford to shop at Whole Foods, Trader Joe’s, and similar venues, your work is easier. Their trained teams have already screened products for you.

Many major-brand cookies, crackers, cereals,doughnuts, and similar items get their appealing texture and extended shelf-life from partially hydrogenated oils. Fast foods are commonly deep fried in hydrogenated oils, which can withstand high temperatures and can be reused. Basically, these mega-million-dollar-manufacturers are cutting their costs at a cost to your health. While their products may be comparatively less expensive on the grocery shelf or in the greasy fast food lane, your cholesterol levels and waistline will ultimately pay the real price.

So, what exactly are these nasty trans fats and why are they so unhealthy?

If an oil is labeled partially hydrogenated, it means that the regular, otherwise healthy, unsaturated version of that oil has undergone the process of being heated, then infused with hydrogen bubbles. The fatty acids in the oil subsequently acquire some of the hydrogenation, which makes them denser. If you fully hydrogenate oil, you create a solid fat out of a liquid (Crisco or stick margarine are examples). If you stop partway, you create a semi-solid, or partially hydrogenated oil, which has the rich consistency of butter.

Both hydrogenated and partially hydrogenated oils are harmful because they contain high levels of trans fats. Trans fats have been shown to raise LDL (bad cholesterol) and to lower HDL (good cholesterol), and to increase levels of lipoproteins and triglycerides—all factors related to heart disease. It is also associated with an increased risk of developing type 2 diabetes.

I banned trans fats from my family’s diet about eight years ago. Do the same  for yours! If you’re not yet convinced, check out these websites.

PS: Naturally occurring trans fats can be found in some meat and dairy products, but they are believed to be significantly less harmful, if at all. I’ll tackle that topic in another blog entry.
