The flavor of the fruit enclosed is outstanding(bluberry) and if there is  a drawback it is that the blanket that encloses the fruit is a bit thick (unlike this companys fig bars) and pastry textured.Flavored with cane  syrup(not fruit juice).150 cal per bar,and low in fat and the carbs(29) not too bad considering the great taste.

Ex Output:
Positive

I bought these for my vegan father who LOVES the curry kale chips by Rhythm Superfoods (my 22 month old daughter, husband and I also like them)!  Thought I would give him a new kale chip flavor--BBQ--as part of his Christmas gift. Although a different brand than we typically eat, they sounded good. First, I was disappointed to see these chips are not kale in its natural curly form but pressed into round, dog-snack-looking discs. Luckily I tried them before giving them. I spit it right out! Was it just me? My husband also tried one and couldn't finish even one chip.  I have a pack of 4 that cannot be returned... what a waste of food and money!

As of Nov 2007, the Keebler website says that each 16 gram serving contains 1 gram of trans fat!  Don't take my word for it that this is terrible, because here are some quotations from the survey article  Mozaffarian et al "Trans Fatty Acids and Cardiovascular Disease," The New England Journal of Medicine, volume 354, pages 1601-1613 (2006).  Here are a few quotations from this article:  "given the 1.2 million annual myocardial infarctions and deaths from CHD ["coronary heart disease"] in the United States, near-elimination of industrially produced trans fats might avert between 72,000 (6 percent) and 228,000 (19 percent) CHD events [i.e. "heart attacks"] each year. These estimates are based on the replacement of trans fats with carbohydrates. In practice, however, trans fats in partially hydrogenated oils would most commonly be replaced with unhydrogenated (cis) unsaturated fats,6 which may have additional potential benefits as compared with carbohydrates. If such additional potential benefit is considered, greater proportions of CHD events (12 to 22 percent) might be averted."  Note that the disproportionate percentage of heart disease attributable to trans-fat is astonishing, since the authors point on on the first page that trans-fat makes up only a tiny proportion of the american diet:  "The average consumption of industrially produced trans fatty acids in the United States is 2 to 3 percent of total calories consumed."  They conclude  "On the basis of evidence from in vitro experimental studies, dietary trials, and prospective observational studies, the consumption of trans fatty acids from partially hydrogenated oils provides no apparent nutritional benefit and has considerable potential for harm."  Professor Willett (one of the co-authors of the above article) is the chairman of Harvard's nutrition department, the author of the medical school textbook "nutritional epidemiology", and the most-cited author in his field. He has also written about trans-fat for a general audience in his book "Eat, Drink, and be Healthy: The Harvard Medical School Guide for Healthy Eating."
