Re: Palm oil lowers blood fats

[Guest guest]

Dave,

Palm oil has a fatty acid profile similar to lard, and by the way,

human depot fat has the same composition as lard. I compiled a table

of the Fatty acid compositions of some common edible fats and oils:

http://www.scientificpsychic.com/fitness/fattyacids1.html

By now all eyes are wide open. How can lard or palm oil improve blood

lipids?!! Mensink and Katan [1] published equations that calculate

the changes in serum lipid and lipoprotein levels caused by isocaloric

exchanges of carbohydrates and fatty acids. In general, reducing

carbohydrates and increasing fats improves triglycerides, HDL, and

LDL. The results are summarized here:

http://www.scientificpsychic.com/health/cholesterol1.html

There is so much negative publicity about lard that most people think

that it a saturated fat, whereas in reality, lard contains 57 percent

unsaturated fatty acids. Note the distinction between PALM OIL which

is OK, and PALM KERNEL OIL which is a highly saturated fat with a

large percentage of myristic acid (C14:0) that increases cholesterol.

P.S.

I found it humorous that the Brazilian subjects were 34 young

individuals (average age 21.9) with an average BMI 22.0 kg per sq. m

In the U.S., you would be hard pressed to find people with a BMI in

the middle of the normal range. :-)

Tony,

Palm oil is okay? I've been seeing so many products in Whole Foods

and Trader Joe's lately that contain palm oil, and I've bought

alternatives without this ingredient (with perhaps canola oil or

butter) thinking I needed to avoid palm oil. All the other

ingredients were acceptable, but then I'd put it back on the shelf

because it contained palm oil. I don't need what are typically snack

foods and cookies for myself, but for children's lunch boxes, I like

to put something fun in so they don't feel deprived. All else being

equal, is palm oil better than butter?

Human depot fat is influenced by the human fat

consumption. If we change the feed of chicken the

composition of their fat changes. It is how we get

more omega 3s in some animals. I am not suprised that

studies done on humans who eat lots of unhealhty fats

show their fat to be similar to the unhealthy fats

they eat.

Palm oil may be the least harmful of the common

tropical oils (and other common animal fats) so of

course, if it is substituted for more harmful fats,

you use an improvement. But i would never consider

it a healthy food.

Palm oil is extremely calorie dense and low in

nutrient density.

Tony,

you seem to place a lot of stock in these equations, you reference

them often. However, aren't their predictions theoretical at present?

From your study:

" Obviously, these questions about diet and coronary

risk cannot be settled by drawing theoretical inferences

from short-term dietary trials. However, our analysis

does raise the question of whether replacement of fat by

carbohydrates rather than replacement of saturated by

unsaturated fats is really the optimal strategy for the

reduction of coronary risk, a question that probably can

only be answered by long-term clinical trials. "

Are there any long term clinical trials proving their mathematical

assertions?

You state: " In general, reducing carbohydrates and increasing fats

improves triglycerides, HDL, and

LDL. "

I have sincere doubt that replacing unprocessed fiber rich vegetables

with fat (ANY type of fat) would improve the lipid profile. Look to

the low-fat research from Ornish, Pritikin etc for evidence of this.

Am i missing smthg here??

As Jeff said, diet does influence fat composition. High cholesterol

levels are generally a sign that a person is eating too many saturated

fats or too many carbohydrates relative to the amount of essential

polyunsaturated fats (omega-3 & omega-6). Carbohydrates that cannot

be metabolized are mostly converted to palmitic acid, a saturated

fatty acid, and stored as fat. The essential fatty acids must be

obtained from food because the body cannot make them.

Based on its fatty acid profile, lard will generally increase your

cholesterol by a factor of 7 more than olive oil. So lard or palm oil

should be consumed in small quantities and they should always be

balanced by an adequate amount of cholesterol-lowering polyunsaturated

fatty acids, as from walnuts, flax seed, and sunflower seeds.

Here is an interesting article about how the ratios of essential fatty

acids of grass-fed beef differ from the conventional corn-fed beef:

There is more than one way to skin a cat. Ornish and Pritikin achieve

good blood lipids through reduced calories, low saturated fat, and

plenty of vegetables. On the other hand, the Atkins diet achieves

improved lipids by displacing carbohydrates with fats.

http://en.wikipedia.org/wiki/Atkins_Nutritional_Approach#Evidence_in_favor_of_th\

e_diet

Blood lipids are just one of a large number of " Health " biomarkers.

The human body is a chemical engine that can run on a variety of

fuels: protein, fat, carbohydrate. We are still trying to find the

optimum ratios of these macronutrients, and the appropriate balances

of their component amino acids, fatty acids, and carbohydrate types.

With regard to the equations, I think that they are good quantitative

tools to help us estimate the effects of diet on the body. Without

quantification there is no science.

You say " I have sincere doubt that replacing unprocessed fiber rich

vegetables with fat (ANY type of fat) would improve the lipid

profile. " Actually, vegetables DO contain fat. Where does corn oil,

peanut oil, sunflower seed oil, or soybean oil come from? Obviously

from vegetables. If you look in the USDA database, you will find that

even romaine lettuce has fat. I think that your point is that if you

already have a good lipid profile, it is hard to " improve " it by

adding oil. You are right.

Hi folks:

Perhaps it is worth remembering in this discussion that, at least as

far as I know, there are only two known ways to reverse clogged

arteries:

1. (Pritikin, Esselstyn, Ornish) eat a diet where fat calories are

10% of total calories, with as little of that fat as possible in

saturated form.

2. (Based on carotid IMT measurements) sizeable caloric restriction.

There is a requirement for fats in the diet, but 10% of calories from

fat with little or no saturated fats, will easily satisfy that

requirement, as I understand it. I believe there is no requirement

for any variety of saturated fat.

It seems to me that the evidence regarding which fats are not

specifically harmful and which are specifically harmful, like much

other nutritional information, is far from being settled. But the

Ornish/CR evidence persuades me.

The conclusion I come to about this is, until the evidence is far

more conclusive, to reduce all fats, especially saturated fats (of

which palmitic is one) as far as is reasonably possible without

becoming fanatical about it. But if you suffer itchy skin

(especially immediately after taking a shower) raise intake of non-

saturated fat until that symptom disappears. And restrict calories.

Of course we all have to draw our own conclusions from incomplete

information, depending on the evidence we happen to be aware of and

the significance we attach it.

Yes, even vegetables contain some fat, but very small amounts--far

less than most whole foods. But your examples of sunflower oil,

peanut oil, and soybean oil are from sunflower seeds, peanuts, and

soybeans. (Those foods are not vegetables.)

I would like to ask how nonhydrogentated coconut oil and palm kernal

oil compare quantitatively with respect to both palm oil and olive

oil (in terms of their effect on blood cholesterol/lipid profile).

Are there any quantitative data of which you are aware?

Thanks,

-Dave

Subject: [ ] Re: Palm oil lowers blood fats

Yes, even vegetables contain some fat, but very small amounts--far

less than most whole foods. But your examples of sunflower oil,

peanut oil, and soybean oil are from sunflower seeds, peanuts, and

soybeans. (Those foods are not vegetables.)

I would like to ask how nonhydrogentated coconut oil and palm kernal

oil compare quantitatively with respect to both palm oil and olive

oil (in terms of their effect on blood cholesterol/lipid profile).

Are there any quantitative data of which you are aware?

Thanks,

OK, right, but I was referring to the effect on

blood profile due to the consumption of the oil,

not the profile of the oil itself. From a

previous post, a statement was made:

" Based on its fatty acid profile, lard will generally increase your

cholesterol by a factor of 7 more than olive oil. "

Is there a similar comparison for palm kernal oil

and for coconut oil, and are there any references

available??

Thanks,

-Dave
