Time for an Oil Change

Posted: 03/16/2012 8:47 am

It's time to change the way you think about fat. For 30 years well-meaning diet gurus have preached that eating fat makes you fat. I'm here to tell you that fat, in and of itself, is not what is making you fat. Instead, it's eating too much of the wrong kinds of fat. After all, all fats are not created equal. But, if you are like 90 percent of Americans, you are eating the wrong kind of fat most of the time. Time for an oil change!

What is Fat?

Fat is one of the body's most basic building blocks. The average person is between 15 and 30 percent fat! Of all of the types of fats in our diets, the body only REALLY needs two -- omega-3s and omega-6s. What is an omega fat? The omega numbers (in this case 3 and 6) refer to where the hydrogen atom joins the fat molecule. Remember, the name is just basic chemistry lingo. What is important is to understand the impact of different fats on body.

The higher-quality the fat, the better your body will function. That's because the body uses fat you eat to build cell walls. You have more than 100 trillion cells in your body, and every single one of them needs high-quality fat. How do you know if your cells are getting the fats they need? Your body sends signals when it's not getting enough good fats. It's up to you to recognize the warning signs:

  • Dry, itchy, scaling or flaking skin
  • Soft, cracked, or brittle nails
  • Hard earwax
  • Tiny bumps on the backs of your arms or torso
  • Achy, stiff joints

Why does the type of fat matter? Building your body from the inside out is just like building a house. You can frame the house with the cheapest stuff you can scrounge. Or you can invest in quality materials that are going to be energy-efficient and last a long time.

Which Fats to Eat and Which to Avoid

If you want to settle for shoddy, stick with a diet of processed foods. Most processed foods are made with poor-quality omega-6 fats because they are abundant and cheap. Plus, fat makes food taste good and improves its texture. Take a look at the ingredients of your favorite packaged food. If the list includes oils made from corn, soy or safflower, you are getting a sub-par fat. When the body puts these cheap fats to work, the cell walls are also sub-par. That means instead of flexible and responsive, cell walls are stiff and rigid. The more rigid the wall, the slower the cell functions and the more vulnerable it is to inflammation.

To ensure your body has the fats it needs to construct high-quality cell walls, you need to eat more omega-3 fats. For starters, cell walls made from omega 3 fats are flexible, allowing cells to respond more quickly to messages. Secondly, these "good" fats help the body churn out prostaglandins, hormones that put the kibosh on inflammation. The best places to find omega-3 fats include cold-water fish, organic canola oil, walnuts, Brazil nuts and sea vegetables.

Your body is designed to run on high-quality fats. Scientists suspect that early humans ate almost equal amounts of omega-6 fats and omega-3 fats. (Back then, most people got their omega-6 fats from seeds and nuts.) But, as people began to refine oils from plants, the ratio became skewed toward omega-6. As a result of fats being out of balance in the modern diet, our bodies are more vulnerable to diseases such as cancer and heart disease. After all, when the human diet contained a balanced number of omega-3s and omega-6 fats, heart disease was almost nonexistent. Now cardiovascular disease is the number one cause of death in the developed world.

Body Boon

The more omega-3 fats you eat, the easier your body cools itself. A cool body is a less inflamed body. And inflammation is at the root of nearly every chronic disease, especially those impacting the brain and the heart (1).

Of all the body parts dependent on high-quality fat, the brain is uniquely vulnerable. That's because the organ brain is made up of 60 percent fat, the biggest portion of which is an omega-3 fat called docosahexaenoic acid (DHA for short) (2). Your brain needs DHA to spark communication between cells. Easy access to high-quality fat boosts cognition, happiness, learning and memory. In contrast, studies link a deficiency of omega-3 fatty acids to depression, anxiety, bipolar disorder and schizophrenia (3).

After the brain, it's the heart that will thank you for eating more omega-3s (4). The heart is a direct beneficiary of omega-3 fats. They tamp down cholesterol by reducing levels of bad fats (triglycerides). Meanwhile, they raise levels of good fats (HDL) in the blood. Part of their magic is that omega-3 fats make blood more slippery, which reduces the likelihood of artery disease.

Beyond the heart and brain, eating the right fat also helps you shed fat. Healthy cell walls made from high-quality fats are better able to metabolize insulin, which keeps blood sugar better regulated. Without proper blood sugar control, the body socks away fat for a rainy day. Ironically, it's not eating fat that makes you gain weight it's eating the WRONG types of fat.

3 Ways to Change Your Oil

The process of rebuilding all the walls of your cells can take up to a year, so there's no time to lose. Here are three ways to change your body's oil:

  1. Eat more wild or sustainably raised cold-water fish. Aim for two servings a week. The best sources of omega-3s are wild salmon, sardines, herring or small halibut. Of course, everyone is concerned about the sustainability and safety of fish. It's important to know where your catch comes from. For more in-depth information about seafood safety and sustainability visit http://www.oceansalive.org/.
  2. Buy omega-3 rich eggs. These are one of the few animal products that are low in toxins and high in quality fats that balance blood sugar. These eggs supply the body with DHA and don't raise your cholesterol; just the opposite. Enjoy up to eight of these eggs a week.
  3. For good measure, take an omega-3 supplement twice a day with breakfast and dinner. Look for a reputable supplement maker that certifies its products are free of mercury and other contaminants. (For more information, see The Healthy Living Store). Choose a supplement with 500 to 1,000 milligrams of omega-3 fats. (A ratio of roughly 300 EPA and 200 DHA is ideal).

Of course, it is understandable that people who try to lose weight do so by eliminating fat from their diets. But remember there is no such thing as a healthy fat-free diet. Fat is essential for good health. The key is knowing how to maximize good fats and reduce bad fats to heap your body protect and rebuild itself every day from the inside out!

I'm not a researcher, just a regular person trying to eat healthy. The big push to use canola oil because it's healthy seems like a big fat lie to me. I try to avoid it as much as possible which is pretty much impossible outside the home. Mark my words ... it will eventually have the same reputation as HFCS and MSG.

One thing that should have been in this article is how eating vegetable oils like Canola, Soybean and Corn oil are not good for you at all. People should stick with good fats like butter, olive oil and coconut oil if they really want to healthier alternative.

All this talk about O'3s and O'6s (especially regarding fish) but not information on WHY we need to take omega 3 supplements and eat fish? Nothing about the omega 6:3 ratio? If you're not talking about these, not a huge difference between you and Dr. Oz...just telling people what they should eat and not why they should eat it.

Science is cool: http://www.ncbi.nlm.nih.gov/pubmed/12442909
Seriously though, read it.

The reason why this ratio is becoming such a problem is mainly because of the meats we eat. The omega 6:3 ratio of grass-fed beef is approximately 2:1 or 3:1. Unlike, what the majority of the world consumes, grain fed beef, which is about 20:1. Like I said, people need to know why to eat they way they should.

Actually, the majority of the world DOESN'T consume "grain-fed" beef ("grain FINISHED" would be a somewhat more accurate term in any event.) The type of "grain-fed' beef you're talking about is really only common in the U.S. and to some extent Canada, largely because the big grain surpluses we've had in the U.S. since WWII, thanks to the development of synthetic nitrogen fertilizers made in converted munitions plants, made it cheap to use grain as animal feed. Shifting away from this "grain-finished in a feedlot" model will do a lot to correct the O6 to O3 ratio.
01:11 PM on 03/27/2012
Apologies for the generalization of the majority of the world, I meant the North American system. I know nothing of beef from other countries and cannot speak for them. But I think we fundamentally agree. The sad thing is that even "grass finished" beef drastically improves the O3:O6 ratio. These improvements can happen after a few weeks actually.

. Dr. Hyman seems to be very political in this article here's why: Large fatty fish such as Tuna, Mackerel etc.. are F**ing loaded with mercury. Do not eat canned tuna--even the FDA instructs women when pregnant to not eat tuna because of Mercury levels that will poison your baby. Fish/krill oil is the best source of Omega 3's--For all you Vegan's the Flax seed conversion to Omega 3's is a myth Plant based omega-3 sources like flax, hemp and chia are high in ALA and are important sources of nutrients as we all need ALA. However, the key point to remember is that the conversion of ALA to the far more essential EPA and DHA is typically severely impaired by inhibition of delta 6 desaturase. This is an enzyme that is necessary to produce the longer chain EPA and DHA from ALA. Elevated insulin levels impair this enzyme and over 80% of the country has elevated insulin levels. So from that perspective alone it is important to include animal based sources of omega-3 fats---Krill/Fish oil highly purified. Forget about plant based Omega 3--it's a myth for the Vegan to feel like his diet has everything his body needs another myth.

Show me how much profit you expect to receive as a result of your sales article being published here on HP. If you donate that profit to charity, then we might consider commenting. But you don't care about that either, do you.

I thought that omega-6 FAs served as the precursor to prostaglandins, thus an abundance would result in abundant prostaglandin production, which is involved in the inflammation process. Some NSAIDs disrupt prostaglandin production as a part of disrupting the inflammation pathway (Brady-Kinen, I believe). Prostaglandins line the stomach, which is why you are not supposed to drink EtOH on aspirin/ibuprofen or take exorbitant amounts. Without the protective layer of prostaglandins, the stomach is at risk for ulcer development.

Eggs (if raised on flax seed), flax seed, and green microalgae (chlorella is popular) are the ones I can name off the top of my head. I think the article also said Brazil nuts.

It's mostly the sugars that make you fat and they increase your appetite.

Fats cut appetite.

Exercise is good for you for many reasons, but weight loss isn't really one of them.

This could have been much better. The important thing is to keep your O'6s low and your O'3s higher--but these should not be the major source of calories. A person doesn't need/use 800 calories a day of O'3s...you need/can use a couple grams. Hyman your gluten article was much better!

Mase,

You need to translate that in english . What is O'6 though ?

omega-6 essential fatty acids

He's talking about the importance of the ratio of omega 6 and omega 3.

The truth about fish:

From where do those healthy, fatty fish get their omega3 fatty acids?

No animal can produce those healthy fatty acids by itself, first they need to eat them.
Algaes are the source of those omega3 fatty acids,eaten by plancton, eaten by small fishes and than eaten by larger fishes.

Algaes are also the source of those conjungated omega3 fatty acids that we have been told, the fish is building up with simple omega3 fatty acids in its body.
But algaes can also produce those.


The sad truth is that the fish population has been depeleted to only 10% of what has been normal before industrialized fishing.

Now if everyone would want to change to fish for their omega3...I think everyone sees the problem.

Omega3 eggs, do you know what the hens are feed to produce omega3 eggs?
Flax seeds, yes that is right,flax seeds whichs oil deliver double the ammount of omega3 than the same ammount of fish oil.

Nuts and seeds beeing the source of omega6 and fish beeing the source of omega3 is not really correct, because it also depends on which plant based oil you use, or which seeds.

Flax seed, rape seed, walnut oil all deliver much more omega3 than omega 6 while corn oil and sunflower oil delivers more omega6 than omega 3 oil.

I eat freshly ground flax seeds in my oatmeal everyday; no need to eat fish if they are too expensive or if there is a question as to their toxicity.
04:41 PM on 03/17/2012
I think that Dr Hyman's basic message here is absolutely correct, although his basic science makes me wonder how he got through medical school. A fully "traditional" diet probably had a 2:1 omega6:3 ratio, whereas the modern diet can be as high as a 20:1 omega6:3 ratio. These fats are usually a minority of all fats in the overall diet. Omega3 acids do NOT make prostaglandins. Omega6 acids do. Omega 3 acids make resolvins, which may oppose prostaglandins. They are also activate the anti-inflammatory GRP120 receptor. Walnuts are high in omega3 acids, and unlike the fish will not add to your mercury burden. However in the what you gain on the roundabouts, you lose on the swings department, most sources of fish will do more good with omega3s than harm with the small addition of mercury.

While I agree with some of what is said here based on science and even common sense, I think a lot of this is faddish pseudoscience that sells books (his books in particular). You can pretty much justify whatever trendy healthy food ideas you want, but most of it doesn't stand up to the test of time.

Why does wild salmon have a better type of fat than farm raised? Also, I noticed it doesn't say anything about olive oil in here... I use a lot of olive oil, and I was under the impression it was good for me...
