'No trans fat' doesn't always mean healthy
By Kathy Warwick kwarwick@canufly.net
New York City Bans Trans Fat In Restaurants!" This was a big headline last week, and the media is buzzing about the move by the New York City Board of Health.
As a nutrition professional, I can agree trans fats will raise the level of bad cholesterol and lower the level of good cholesterol in the blood. We are all aware high cholesterol levels can increase the risk of heart disease. On the other hand, I think the Health Department may have missed the boat if its intention was to decrease rates of obesity in the city and impact health care costs.
Restaurants will be asked to replace the trans fats in their menus with more heart-healthy fats such as peanut oil, canola oil or olive oil. Even these heart-healthy oils contain a lot of calories - in fact, the same number of calories per measure as the trans fats. One tablespoon of any oil has 120 calories. Therefore, restaurants can still serve very high-calorie, high-fat menu items. Obesity is caused by taking in more calories than we burn up with exercise and daily activity, no matter where we get the extra calories. If we eat too much organic health food and we don't exercise, we will gain weight over time.
Most cookies, crackers, baked goods, chips and snack foods have been produced with trans fat because it helps keep these foods from getting stale on the grocery store shelf.
Now manufacturers are looking for a fat to substitute for trans fat in these products. Many are using other saturated fats such as coconut oil, palm oil or real butter. Because they contain saturated fats, these snacks can raise your cholesterol levels and may have lots of calories. The average consumer sees the packaging with "No Trans Fat" in bold letters and assumes he or she can eat as much of this "healthy" snack food as desired.
One New York restaurant owner was quoted as saying, "In this country, there are so many obese people. It is really a disgrace. When I was growing up in France, my mother never gave me a French fry. We don't have a fryer here in the restaurant, we just saute our potatoes in real butter."
This statement just goes to prove how confused everyone really is when it comes to the fat debate. Real butter is a saturated fat. If I cook all my low-calorie vegetables in butter or bacon grease, they become high-calorie and can raise my cholesterol, but they can be labeled "no trans fat."
When we take in more calories (from any source) than we burn up, we will gain weight. Obesity is a risk factor for diabetes, heart disease and cancer. Banning trans fat from restaurant menus will do little, if anything, to decrease obesity. Until individuals take some personal responsibility for cutting calories and increasing activity, obesity levels will continue to rise. Waiting for the government to legislate us into good health is pure folly.

Interesting. The restaurant owner says clearly that here in the US, there are so many obese people. Then he says that they don't eat french fries (a lot of carbs), but they eat a lot of food, including potatoes, sauteed in butter. He did not mention that they don't eat all their meals with a half gallon jug of hfcs soda.
So the french eat a high animal-fat diet with little refined carbs and they are less obese and more healthy than the americans eating generally lower fat and higher carb diets.
And she tries to infer that the restaurant owner is confused about calories. Calories mean squat in the face of a diet full of highly processed crap carbs and fake fats.

Be careful about connecting dots that aren't there. The French do many things quite different from us obese Americans.

monty1945@lycos.com - 13 Dec 2006 05:00 GMT Patrick:
Farmers determined long ago that soy and corn really fattened up their animals, whereas coconut oil kept them slim. Have you ever heard of the phrase, "the corn-fed farmer's daughter?" This referred to a young woman who was not slim. You can do your own experiment with rats and see for yourself. Feed one group of rats corn oil at 25-30% of daily calories vs. another group getting coconut oil at 25-30%. See what happens.
As to the claims being made by various "experts:" whether something like coconut oil raises your cholesterol or LDL a little is totally irrelevant. Even AHA spokesman Dr. Richard Stein pointed out that only oxidized cholesterol is dangerous, and saturated fatty acids do not oxidize cholesterol. Unsaturated fatty acids can, especially the want they are consumed by Americans. This is a major problem, along with cooking meat. Eggs, though high in cholesterol, appear to be reasonably healthy if boiled. Enig and Fallon point out that freezing meat for more than 2 weeks, then eating it raw is best. However, there is still a lot of iron, unsaturated fatty acids, and an amino acid profile that is sub-optimal, at best.

dorsy1943 - 13 Dec 2006 14:50 GMT Monty, what does happen with corn oil vs coconut oil when feeding rats? There must be cultures which eat coconuts (do they extract the oil and eat it alone?) as part of a traditional diet and are healthy as far as they continue their traditional diet. It also occurs to me that perhaps these traditional cultures consume a lot of fish. Do you know which groups of people eat a lot of coconut oil as part of a traditional diet and remain healthy?
I also have to say again that cows are not only fed corn, but about 15% protein as a finisher. They are also kept immobile, doused with antibiotics and hormones and the males are castrated. Cows are natural grazers not corn eaters. They are practically force fed the corn at the finishing stage. I bet if you eliminated the hormones, didn't castrate the males, fed them corn as a small part of their diet and gave them gym memberships they wouldn't end up so fat. There are also whole cultures of people who traditionally eat corn (not corn oil) in some form as a mainstay of their diet and as long as they eat the corn along with squash, beans and anything else they forage or trap, are perfectly healthy and slim. What else is the corn fed farmer's daughter eating besides the corn? Dolores

Actually cattle are probably a good test group, in that you can be fairly well assured that their activity levels will remain fairly constant regardless of what they are fed. And they are fed grains to fatten them up. I think we can agree that grains are higher in starch content than grasses. And the are not "kept immobile", they are allowed to roam and graze at will. And they were fed grains to fatten them up before the use of hormones became widely practiced. As far as castrating them is concerned, we can default to only the females and you will see the same thing, grains = fattening.

This is being done all the time intentionally. When researchers need groups of rats with various metabolic disorders upon which to do research they feed them a high saturated fat diet of 60 percent. This has become a standardized diet for this purpose sold by one company. All the fat in the diet is 100 percent coconut oil. One strain of rats responds to this diet by getting diabetes and others various heart disease related disorders.

If that were the case, the Pilgrams would have expirenced a lot of fat native American girls.

No disrespect, but if I ever get to the point where I'm eating raw meat/frozen and then thawed meat/only boiled eggs, call the guys in the white coats and have them bring me over and fit me in one of those jackets that tie in the back.
Instead, I think people would be MUCH better served, and lifespans noticeably lengthened, by avoiding all forms of motorized transportation, living in a home free of any carpeting, paint, insulation etc., and maybe by staying away from all high-voltage power lines, cellular transmissions and radar. (Now who does this?)
Screw that! I'm going to enjoy life, and food, and continue eating omeletes, grilled buffalo burgers, soybeans on my salads and corn on the cob.

Even AHA spokesman Dr. Richard Stein pointed out that only > oxidized cholesterol is dangerous, Funny how much stock you put in a statement by a paid spokesman, when it suits you, but anyone who disagrees with you is an "industry shill".
Raising LDL levels isn't irrelevant either. If you understood what the process leading to LDL oxidation and atherosclerosis was you'd know that the more LDL there is, the more chance it's going to end up oxidised and lodged in an artery wall.
> and saturated fatty acids do not > oxidize cholesterol. Your evidence for this? Coconut oil oxidizes DNA:
Oxidative stress related DNA adducts in the liver of female rats fed with sunflower-, rapeseed-, olive- or coconut oil supplemented diets.
"1,N(6)-ethenodeoxyadenosine (etheno-dA)...were determined as markers for DNA-damage derived from lipid peroxidation products and markers for oxidative stress." "Highest adducts levels of etheno-dA (133 +/- 113 adducts/10(9) parent bases) were found in coconut oil diet (lowest content of linoleic acid)."
What's your molecular level explanation for that?

dorsy1943 - 13 Dec 2006 09:11 GMT I don't eat trans fats or hfcs if I can help it. If the French don't eat this junk, there are also other things the French and those from some other cultures don't do. A friend from Tanzania told me that when they moved here they were amazed at the portion sizes. She said in Tanzania and Europe, a sandwich was thinly sliced bread with a thin slice of ham between the slices. My kids were friends with exchange students who were also amazed at portion sizes. We Americans feel we are not getting our money's worth unless the restaurant serves us a potato the size of Rhode Island and a steak large enough to feed a small African Village. And by golly the meal better come with a salad bar.

Healthy oils? Peanut and Canola? WOW.
I'm not sure who is being quoted in the above but 'canola' oil is a smoke screen to hide that fact of what 'canola' oil really is. (it's rape seed oil) Do a web search to learn the nasty truth about this 'healthy oil'.
And peanut oil is very high in poly-unsaturates. So that sure wouldn't be my first choice for a 'healthy oil'.

It appears to reduce heart disease. -- Jim Chinnis Warrenton, Virginia, USA jchinnis@alum.mit.edu
monty1945@lycos.com - 13 Dec 2006 22:52 GMT "It's not rapeseed oil. It's produced from a plant developed in Canada FROM rape. It appears to reduce heart disease."
Rapeseed oil is often used in "junk food," at least around here. Go to your local supermarket and just read the ingedients lists.
As to "appearing" to "reduce" heart disease: most of the time this means that something lowers cholesterol levels slightly. As biologist Ray Peat pointed out long ago, this is a toxic effect, not a beneficial one. Again, all one needs to do is to feed one group of rats or dogs a 30% canola oil diet and compare their lives to a group of the same species fed 30% good quality coconut oil, and see what happens. If you don't understand the molecular-level evidence that I present on my site, and if for some reason the raw demographic data does not strike you as convincing (though I can't imagine why), then you can do your own experiment and demonstrate it to yourself. If you are so sure about how healthy canola oil is and how "bad" coconut oil is, then you can take me up on my offer. If you are right, you pay for nothing.

What about hamsters?
From:
Different palm oil preparations reduce plasma cholesterol concentrations and aortic cholesterol accumulation compared to coconut oil in hypercholesterolemic hamsters.
"The coconut oil-fed hamsters also had significantly higher plasma lipid hydroperoxide concentrations compared to RBD-PO (112%) and the reconstituted RBD-PO (485%)"
i.e. there were *more* oxidised lipids from eating 10% coconut oil than 10% palm oil.
> and if for some reason the raw demographic data does not strike > you as convincing (though I can't imagine why), What data would that be? Are there human populations that eat 30% of a single oil?

Canola is a GM rapeseed. And the oil has to go thru some severe processing to minimize its content of toxic erucic acids.
And you used the right word in that it "appears" to reduce heart disease. Then again there were "studies" that made it "appear" that hydrogenated oils were healthy too. And Ancel Keyes made it "appear" that "saturated" animal fats were causing heart disease.
So Keyes was wrong about saturated fats and they were wrong about hydrogenation. What are the chances that they are right about genetically modified , previously toxic, rapeseed oil being healthy?
