Medical Forum / General / Nutrition / May 2005Partially hydrogenated oil and NO trans fats?
A product I was looking at (a chocolate bar) list "partially hydrogenated palm kernel oil" among the ingredients, however it claims to have 0 Trans Fat. How can that be? I thought trans fat is always formed when vegetable oils are hydrogenated.

How can that be? What brand is it? Anyway, try real pure chocolate, which contains cocoa butter and no other vegetable fats! :-) > I thought trans fat is always formed when vegetable oils are > hydrogenated. Hmmm... I asked a similar question a few weeks ago ("A few questions about hydrogenated fats").

However, I read... http://www.mypyramid.gov/pyramid/discretionary_calories_fats_how_print.html | Foods containing partially-hydrogenated vegetable oils usually contain | trans fats. They say "usually", not "always". Besides... http://www.mypyramid.gov/pyramid/oils.html | Check the Nutrition Facts label to find margarines with 0 grams of trans | fat. Amounts of trans fat will be required on labels as of 2006. Many | products already provide this information. But such a label might refer to margarines with no hydrogenated fats at all, I suppose. At the end of day... sorry, I don't know the answer! :)  SignatureEnrico C > On 18 May 2005 10:16:14 -0700, ll1ff@hotmail.com wrote on > sci.med.nutrition [quoted text clipped - 29 lines] > > They say "usually", not "always". The reason to this is, and I think I also mentioned that in the discussion where the quote is from, that the hydrogenation process is getting better and better. The ammount of trans fatty acids that results from a modern hydrogenation process (new catalysators etc) is very small to practically zero. I would expect the "0 trans fats" to be read as "0 grams" which basically means that there might still be trace ammounts in there but not in the area of one gram. Trace ammounts of trans fats are absolutely harmless.. trans fats are not the "killers" anyway because the ammounts are very small and they have similar properties to saturated fats when it comes to LDL cholesterol. > Besides... > [quoted text clipped - 7 lines] > > At the end of day... sorry, I don't know the answer! :) > A product I was looking at (a chocolate bar) list "partially > hydrogenated palm kernel oil" among the ingredients, however it claims > to have 0 Trans Fat.

This happens because the stated "0" per serving only has to be "close" to the actual value per serving, not exactly the actual value per serving. I forget the amount of leeway you have, but I think it's close to 25% plus or minus the actual value, but I could be wrong. >> A product I was looking at (a chocolate bar) list "partially >> hydrogenated palm kernel oil" among the ingredients, however it [quoted text clipped - 7 lines] > serving.

Such mix in right proportions would have the consistency of the partially hydrogenated oil, but won't have trans fats. Sometimes such mix is still called "partially hydrogenated oil".

How can that be? How much polyunsaturated fat does palm kernel oil start with? My understanding is that the serving size is reduced until the transfat (or sugar) is less than half a gram per serving. They are then allowed to say zero on the label, even though the product may, in fact, contain the trans fat or suger. It could be 10%. > A product I was looking at (a chocolate bar) list "partially > hydrogenated palm kernel oil" among the ingredients, however it claims > to have 0 Trans Fat.
