When 100 % hydogenated, it's safe. Not obligéd to be mentioned under 2%.

Unsaturated Vegetable Oils: Toxic - Ray Peat
Q - Is margarine okay?
RP - There are several problems with margarine. The manufacturing process introduces some toxins, including a unique type of fat which has been associated with heart disease. [Sci. News, 1974; 1991.] There are likely to be dyes and preservatives added to margarine. And newer products contain new chemicals that haven't been in use long enough to know whether they are safe.
However, the basic hardening process, hydrogenation of the oils, has been found to make the oils less likely to cause cancer. If I had to choose between eating ordinary corn oil or corn oil that was 100% saturated, to make a hard margarine, I would choose the hard margarine, because it resists oxidation, isn't suppressive to the thyroid gland, and doesn't cause cancer. Ray PEAT, PhD. From interview on “Unsaturated Vegetable Oils: Toxic”. 2006.
=> 100% saturation destroys all trans fats and PUFAs. Unfortunately, most margarines are partially hydrogenated. -
There is no trans-fat in full saturated fat
From the "project well-being" website:
Saturated fat has zero trans-fat.
Trans fat and cis fat require at least one double bond, and there are no double bonds in saturated fat.
As hydrogenation of unsaturated oils begins, some of the double bonds are reduced to saturated (single) bonds, and some are interconverted between cis and trans form. In a free radical environment, cis and trans fats interconvert, with trans fats being a bit more stable than the cis fats. So oxidizing conditions (heating fat in air for frying foods) and reducing conditions (hydrogenation) can both produce trans fats. But when hydrogenation is taken to completion, there are no double bonds left, and no cis fat and no trans fat. Zero. Nada. Even if there was trans fat to start with, there is no trans fat left at the end. Even if it was 100% trans fat at the beginning, it is zero trans fat at the end.But what if the hydrogenation is not taken to completion?
Then there are trans fats. This is “partial hydrogenation.” The trans configuration of double bonds is energetically and entropically favored over the cis configuration. Commercially, hydrogenation is rarely taken to completion. So if it doesn’t say “fully hydrogenated,” it probably isn’t. Then again, even if it does, it might not be.
The FDA deliberately corrupted the regulations for labeling requirements on behalf of the food industry so that cholesterol, trans fats and other (supposedly) bad things can say zero on the label when it is not actually zero. As long as the amount can round down to zero based on the serving size, it can say zero on the label. And as long as the preservatives in the food were not added by the labeler, they can say “no preservatives,” which is short for “no preservatives added (by us).” Of course, the ingredients used to make the food under the label are usually fully preserved. So maybe “partially hydrogenated” can be shortened to “hydrogenated” and “fully hydrogenated” does not really mean 100% under FDA labeling regulations.

@LucH 2% of what?

2% of what?
The body can manage 2 % maximum of trans fat.
2% of the amount of fats brought by food, logically. -

2% of the box / amount ot sold margarine.

@LucH - Thanks for all of the information.
Fat hydrogenation is the process of combining unsaturated fat with hydrogen in order to partially or completely convert it into saturated fat. Typically this hydrogenation is done with liquid vegetable oils resulting in solid or semi-solid fats.
With coconut fat, the resulting oil is liquid at room temperature.
-
Coconut oil is 92% saturated.
Interestingly, beef fat naturally contains trans fat.

@winters2 sounds like you’re trying to gain weight. if that is the case, why not just eat more of the foods you like (that happen to be bio energetic)? You’ll end up getting more calories/fat in a more appealing way. For example I’d make myself homemade piña coladas (light on the alcohol) with real coconut cream, or thai coconut curry (light on the spices)
Regarding dairy fat, i would concentrate more on butter and less on cream, because butter is usually less adulterated. -
Coconut Oil: Healthy or Not? Brief oriented summary.
- Anything in excess, whether coconut oil or any oil rich in PUFA, is harmful.
- Consumption exceeding the body's PUFA needs could have a long-term impact on metabolism (mitochondrial respiration: slowed metabolism) and weaken membranes (oxysterol formation) if stored. This will very often be the case if...
- A balanced intake of fatty acids should be around 40-40-20, rather than 20-30% SFA, 55-65% PUFA, and 10-20% PUFA, if you eat homemade food.
Note that anything above the body's needs is harmful, especially polyunsaturated fatty acids, which will be stored. Sooner or later, the bill will have to be presented. I would therefore aim for 10% PUFA, just to ensure basic needs.
Best contributions of fatty acids
- If you store (fat belly), it means you need to change something in the equation. Not necessarily the proportions above. Not everything is black or white.
