Good Peanut Butter vs. Bad Peanut Butter

The peanut butter said something like 16 g per serving fat, 3 g. saturated fat, so that left 13 grams PER SERVING of unsaturated fats, many of which are hydrogenated. I threw the jar out. [snip] Leila (ducking for cover) I'm wondering about your calculations. I don't think that total fats - saturated fats is equal to trans fats. I think the peanut oil in the peanuts is unsaturated and makes up almost all of the total fat - saturated fat number you computed. The Skippy web page: http://www.peanutbutter.com/faq.asp referenced previously in this thread states: "Does Skippy peanut butter contain trans fats? By U.S. FDA definition, Skippy peanut butter is a trans-fat free food. Most commercial peanut butters contain small amounts (typically less than 2%) of a partially hydrogenated fat, which prevents oil separation by helping the peanut butter "set up" a fat structure. This partially hydrogenated fat is almost totally saturated and contains only an insignificant trace amount of trans fats. " I looked for the US FDA definition of trans-fat free and found a page about the proposed trans fat labeling rules: http://vm.cfsan.fda.gov/~dms/qatrans2.html which states in part: "Q: Is it possible for a food product to list the amount of trans fat as 0 g on the Nutrition Facts panel if the ingredient list indicates that it contains "partially hydrogenated vegetable oil? A: Yes. Food manufacturers are allowed to list amounts of trans fat with less than 0.5 gram (1/2 g) as 0 (zero) on the Nutrition Facts panel. As a result, consumers may see a few products that list 0 gram trans fat on the label, while the ingredient list will have "shortening," "partially hydrogenated vegetable oil," or "hydrogenated vegetable oil" on it. This means the food contains very small amounts (less than 0.5 g) of trans fat per serving." So my guess is that Skippy has less than 1/2 g of trans fat per serving. I can't believe other big brand name peanut butters are that different. It might be good to avoid even small amounts, but I think that your idea that each serving of your peanut butter contained many grams of trans fats is way off. I think commercial cookies, crackers, donuts, fried foods and margarines are all much more significant sources of trans fats than peanut butter in the average american diet. Peggy |

Peggy Trans- fats are saturated. That's why they are solid. Roughly half of hydrogenated fat is trans- and the other half is... ummm... "cis-", I think. Peanut oil contains a little bit of natural saturated fat, all of which will be "cis-". So, Skippy probably has about 1 gram of hydrogenated oil per "serving", half of that is "trans-", or .5 grams. They adjust the serving size down small enough to stay below the .5 gram limit. Best regards, Bob |

The rumors no doubt started because small amounts of hydrogenated vegetable oils are added to commercial peanut butters--at 1 to 2 percent of total weight--to prevent the peanut oil from separating out. And the hydrogenation process can generate the formation of trans fatty acids in oils, according to Timothy H. Sanders, who leads research at ARS’ Market Quality and Handling Research Unit at Raleigh, N.C. To see if the rumors had any validity, Sanders prepared 11 brands of peanut butter, including major store brands and natural brands, for analysis by a commercial laboratory. He also sent paste freshly prepared from roasted peanuts for comparison. The laboratory found no detectable trans fats in any of the samples, with a detection limit of 0.01 percent of the sample weight." ************************** Sue(tm) Lead me not into temptation...

I can find it myself! Thanks! When I was explaining it (wrongly) something didn't seem right, cuz if the fat is completely saturated it will just be a chain of single-bonds. So trans- fats would just be a problem in *partially* hydrogenated oils. I still prefer to grind up roasted salted peanuts without any sugar or shortening added. Health food store bulk peanut butter doesn't have enough salt. Best regards, Bob |

But there do not really seem to be any trans fats to skip, in Curly Sues post I read: "The laboratory found no detectable trans fats in any of the samples, with a detection limit of 0.01 percent of the sample weight." And reading the full article at the link Curly Sue provided, I found this elaboration: "That means that a 32-gram serving of any of the 11 brands could contain from zero to a little over three-thousandths (0.0032) of a gram of trans fats without being detected." And in any case, I'm not sure my kids (who prefer Skippy or Jif to natural peanut butter) would accept wine or coffee and jelly sandwiches as a substitute -- although they might like chocolate and jelly ones.

It's not as if natural peanut butter is difficult to come by. -- jmk in NC |

Who did you ask? From the information in Sue's post and my post, it is *not* one gram per serving, it is 1/100 of one percent of the sample size, which the part of my post you cut out (or simple arithemtic) computes as .0032 grams for a 32 gram serving (which seems to be the standard serving). An 18 oz jar of peanut butter contains about 16 of these 32 gram servings for a total of about 5/100 of a gram of trans fats in the entire jar. So one would need to eat 20 jars to injest one gram of trans fats. Moreover, these numbers just represent the most that could be present without being detected, in fact none was actually detected. Here is the link to the page Sue found again: http://www.ars.usda.gov/is/pr/2001/010612.htm Check it out. Peggy |

Perhaps however, the 0.8 grams (or something) is the quantity of hydrogenated oils added -- almost all of which are not trans fats according to the USDA study. Peggy Right. That's why I e-mailed them. It says 0 but I think that it means "less than 1." I wanted to confirm that. Anyway, I like natural peanut butter and it is readily available so that is what I get. It was more a curiosity thing that anything. -- jmk in NC |

I said that when I contacted the company they said that Skippy contained .8 g of transfats per serving, if I remember correctly. Since there is an alternative (peanut butter without hydrogenated stuff) and I do think that transfats are probably not a good thing, I don't eat it. That's just me though. -- jmk in NC |
