Beware of Fat…Is Saturated Fat the Answer?
Nutrition January 12th, 2008Beware of Fat…Is Saturated Fat the Answer? By Angela Pifer, MSN Certified Nutritionist
It’s time to put your guard up as saturated fats threaten an attack and make their way back into your diet. How do you fight? First and foremost, knowledge is your best contender. Despite the recent entourage of new ‘reduced’ and ‘trans-fat-free’ products on the market, be warned that ‘fat-free’ may be anything but.
Trans fats are a type of mostly man-made fat that the food industry loves, but our hearts and blood vessels do not. In the late 19th century, chemists discovered that they could turn liquid vegetable oil into a solid or semi-solid by adding hydrogen atoms to the fat backbone. They did this by bubbling hydrogen gas through vegetable oil in the presence of a nickel catalyst. This was far more than a chemical curiosity. Partially hydrogenated oils don’t spoil as easily as non-hydrogenated fats. They can also withstand repeated heating without breaking down. These characteristics were attractive to food makers. Over time, partially hydrogenated oils became a mainstay in margarines, commercially baked goods, and snack foods.
The FDA once estimated that approximately 95% of prepared cookies, 100% of crackers, and 80% of frozen breakfast products contained trans fat. Now that trans fat must be listed on food labels, some companies are scrambling to remove them from their products. Many others have already succeeded in going ‘trans-fat’ free.
The shift follows the growing realization that trans fats are even worse for the heart and blood vessels than saturated fats. Truth be told, there is an uprising in the food industry resulting in a trade-off of fats. It is true that the labels will demonstrate a reduction in trans fat, however, this is often replaced with saturated fat found in tropical oils. Though researchers announce that tropical oil fats, such as coconut, palm kernel oil, and palm oil, are safer than previously recorded, these newly found foods, actually result in more saturated fat content than the original formula.
Trading fats is not the answer.
Saturated fats are generally solid at room temperature (butter is a good example.) They are most¬ly found in animal fats, including meat and dairy products, as well as in certain tropical plant oils such as palm and coconut oils. The human body has the ability to produce sufficient saturated fat for its needs. Therefore, saturated fats are not considered essential. In fact, saturated fat should be limited as these fats can play a role in increasing cholesterol levels, which can lead to heart disease. Consumption of saturated fats has also been associated with an increased risk of obesity, heart disease and high cholesterol. It is as important to look for ‘trans-fat free’ on the label as it is to choose foods that do not list ‘hydrogenated’ among the ingredients.
All is not lost; however. Become aware of the healthy alternatives including ultra-low-linolenic soybean oil and high-oleic canola oil. The healthier oils such as soybean oil, canola oil, sunflower oil, and safflower oil, can be found in food favorites such as: Goldfish crackers, Nutri-Grain Cereal Bars, Bear Naked All Natural Granola, and Healthy Valley Chocolate Cookie Cremes. One of the leading distributors of trans-fat-free oil, Asoyia, indicates that today’s demand is ten-fold from last year.
Power is knowledge and knowledge is power. Trans-fat and tropical oil based saturated fats are still fattening. Arm yourself with the knowledge that there are healthier alternative oils available to you. Of course FRESH is best and pre-packaged or processed foods should be eaten in limited quantities. Therefore, ‘whole’ foods, lean proteins, fruits and vegetables should top the list of healthy picks.

Great information. Thank you!

I agree fresh is best, but given all the choices you’ve laid out some good intel. Thanks for coming back. I’m going to enjoy your site.

Thanks, this was a great post! Its good for people to learn that while trans-fat is constantly talked about being bad, that saturated fats aren’t better to switch to. I wish more people would eat fresh foods and not processed junk, I think the prices would come down with more money going into better products.

Thanks for sharing this. I would love to know a bit more. Can you share more on which cancers have been associated with saturated fats. Can you share if one saturated fat is worse than another? I noticed olive oil wasn’t on any of your lists. I understand it falls into the “good oils” category, but I’m not sure where it falls. Charts on the various oils would help “visual” people like me :).
Also, I’ve heard that as the processed food industry creates low fat processed foods, they tend to make up for it in higher sugar contents (especially processed corn syrups and the like) and salt/sodium content. I don’t know how true this is. Can you enlighten me?
Again, thank you!

Here I am already correcting myself. I am still getting used to blogging and I must admit that my fingers sometimes work faster than my brain. When it comes to saturated fats, cancer isn’t as much of an issue as obesity, heart disease and cholesterol (it has not been specifically linked to cancer, yet). We have all heard of LDL and HDL, basically transporting lipo-proteins for cholesterol and fats within our blood stream and liver. These transporting lipo-proteins have receptors on their surface which key to cells and then unload their contents. The more saturated fat you have in your diet, the more likely it is that you have higher LDL levels and lower HDL levels. Each of which have been highly associated with heart disease and stroke.
Trans fats are even worse. Instead of packaging along with the LDL transporting lipo-proteins, trans fats create a very dense lipo-protein. With less surface area, these are usually void of receptors and are unable to key to cells and unload their contents. Instead, these dense proteins build up in the blood stream creating a high risk for atherosclerosis.
Olive oil is a good oil to use. I also suggest using extra virgin coconut oil to sauté with. It has a higher smoke point than olive oil and, though it is a saturated fat, the length of its fatty acid chains, also called a “medium chained” fatty acids compared to other saturated fats which have “long chain” fatty acids, means that it has a different absorption point in the intestine and does not utilize the lipo-protein transport system referenced above. But, please don’t believe the hype most websites offer. It is not a cure all for anything; just a good oil to use to sauté at higher temperatures. (Please note: when something sounds to good to be true, ask yourself what the person is selling).
The following chart shows the breakdown of the types of fats and their sources. Focus as much as you can on the fats from the first two columns, omega-3 and monounsaturated fats, and completely omit the fats from the last column, hydrogenated oils and trans fats.
Omega 3 Fatty Acids
Flax seed & flax seed oil,
Oils of cold water fish:
Salmon
Mackerel
Herring
Trout
Mono-unsaturated Fatty Acids
Olive oil
Canola oil
Hazelnut oil
Almond oil
Avocado
Polyunsaturated Fatty Acids
Omega 6 Fatty Acids
Richest sources:
Safflower, sunflower and corn oils.
Good sources: pumpkin seed, soybean, walnut, wheat germ, sesame seed, rice bran oil
Supplements: evening primrose, borage, & black currant seed oils.
Saturated Fats
Beef, Iamb, pork, butter, lard, coconut oil, palm oil, palm kernel oil, cocoa butter, eggs, cheese, whole & 2% milk, poultry, ice-cream
Hydrogenated Oils & Trans Fats
Margarines, shortenings, breads, muffins, snacks, cookies, and crackers, french fries, donuts and other fried foods
To answer your other question, about corn syrup and salt, I say this: read all labels and be sure that you are not drinking or eating anything that has high fructose corn syrup or corn syrup in it. This immediately tells me that the ingredients are inferior and they need to up the sweet factor to make it palatable. To follow the information above, I would also replace anything that lists ‘hydrogentated’ on the label. This will clue you in that the product does contain trans fats, even if the packaging says it doesn’t. Remember that the manufacturer can say ‘trans fat free’ if each serving has less than .5 grams of trans fat. Current government recommendations are

Wow! Thank you. I actually did a lot of cooking with Hazelnut oil this summer when I was attempting to do a 100 mile diet. This oil is actually produced in the pacific northwest.
I’m curious about the fish. I had no idea there was a difference in cold water fish v. warm water fish. So, are the oils in warm water fish so much different?
Very interesting. thanks!
January 15th, 2008 at 6:31 pm
Hazelnut oil is great oil to cook with and it has a much higher smoke point than either olive oil or coconut oil. Where did you source this?? I didn’t realize there was a company in the Pacific Northwest that manufactured it.
There is less difference in the types of fat present in cold water vs warm water fish, as much as how much is present. Cold water fish have a greater level of fat present…simply for survival.

I found the hazelnut oil at the Phinney Ridge Farmer’s Market (now closed for the winter). But, I have the bottle! Holmquist Hazelnut Orchards from Lynden, Washington was the seller. Looks like they sell it online too: http://www.holmquisthazelnuts.com/Departments/Hazelnut-Oil.aspx
If you’re up for another article, I’d love to see a piece on sweeteners. I’ve started using Agave nectar in tea rather than raw sugar, stevia or honey. I understand that it is relatively low on the glycemic scale and it comes from a plant not a chemical plant, which is good. But, I don’t completely understand the glycemic scale. Thanks for any input. I really appreciate what you share with us!

I’d love ot see the same thing - and ditto on the usage. I use Agave, but I still use stevia or even (i know… bad) Splenda at times. I get severe headaches from refined sugars, and I also have allergies to gluten, dairy, and preservatives. I started doing research on Splenda for my fitness class last year but switched topics… the research/info available on this sweetener is so controversial… any thoughts? (I also heard that stevia may harm female fertility - is that true?)
thanks!

I had a question: how bad is using peanut oil to cook with? I know there are the good oils to use (canola) and there are the bad, but you didn’t mention peanut. Just thought I would ask. Thanks!
April 30th, 2008 at 4:03 pm
Nut oils are absolutely considered healthy to use. Most oils do not have a high enough smoke point to use in a frying pan. Both peanut and sunflower oils have a 450 F smoke point, making either of them healthy choices. What you need to look for is whether the oil is the level of refinement. The less refined it is, the healthier it is, and (usually) the lower the smoke point.
Unrefined peanut oil (smoke point is below 320 F)
Refined peanut oil (smoke point is below 450 F)

Thank you very much!

Great info. Thanks to all.

i am a very picky eater. in training for a triathlon, what are the necessary foods i need to eat to maintain. i eat alot of chicken and use supplements but i know there is a healthier way.
May 3rd, 2008 at 2:30 pm
That’s a great question…but you can understand that there is are a broad set of answers that would apply. Chicken and supplements are not going to supply you with the necessary nutrients to train and compete in a triathlon. Yes chicken is a great source of lean protein and supplements supply a specific array of nutrients and yet you will miss out on thousands of bioactive compounds if you are not making a concerted effort to get your nutrients from food (like that you are taking supplements, but they should do just that, ’supplement’ a health, whole and sound diet). I offer a 90 minute consult. We could go over a few days of food journaling and I could tell you what is and isn’t working for you and then make some recommendations based your your tastes and lifestyle.
