Fried Chicken and Alex
I closed last week’s column with a brief mention of the death of Alex, the African grey parrot that had been taught and studied by Irene Pepperberg and her colleagues for some 30 years. Alex deserves more than just a passing mention. In last Sunday’s New York Times there was an article about Alex. The article, by George Johnson, cites a couple of incidents supporting the view that Alex possessed a sense of awareness that some maintain is characteristic of only us humans. Regular readers of these columns will know that I love to write about animal behaviors that show we’re not the only intelligent beings on this planet. I particularly enjoy pointing out instances where the derogatory term “birdbrain” doesn’t apply to certain birds.
Alex’s ability to count (up to 6), to distinguish colors, objects and their sizes were remarkable but what most impressed me most were reports of his showing frustration when subjected to prolonged experimentation and his demonstrating what might be considered a wry sense of humor. In the counting game, Alex apparently grasped the concept of zero, a concept not that easily understood by young humans. For example, Alex, was presented with the old carnival shell game. An object, a nut in Alex’s case, is placed under one of three shells and the shells are then moved round. Alex was obviously quite upset when he picked what should have been the shell containing the nut and there was none. He sensed there was nothing there. Zero.
In another experiment, Alex was presented with groups of two, three and six objects. Within each group all the objects were the same color. In response to the question, “What color two?” Alex would normally give the correct color for the group containing two objects. One day, however, Alex was not really in the mood for such shenanigans and when asked, “What color three?” he replied “Five”. There was no group of five objects. Repeating the question evolved the same response from Alex. Finally, the researcher gave in and said, “OK. What color five?” “None”, Alex replied, using the word he had learned years before in a different situation. Not only did Alex seem to know the concept of nothing, or zero, but I can also imagine him feeling quite smug about toying with the questioner.
Another of my favorite birds is the chicken, not for its intellect but for its tastiness. Here at home, I’m again in the care-giving mode, my wife having returned from rehab after surgery last Saturday. While in rehab, she received an amusing card from our good friends in Dallas. On the front of the card was a colorful, mouth-watering picture of fried chicken arranged around a cup of dipping sauce on a platter. The caption above the picture read “They gave their lives so that we might celebrate.” Open the card and you’re greeted by a loud and surprisingly high quality musical rendering of what my wife tells me is the “Chicken Dance”. On the empty platter are the words “Let us dance to their memory.”
If I have a choice of my last meal on Earth, I will choose my wife’s fried chicken as the entr e. For the last few decades, following the conventional wisdom regarding fats, I’ve been reluctantly discarding the skin on my favorites, the leg and the thigh. But wait – the September issue of the Harvard Health Letter’s lead article is titled “Time to fatten up our diets” with the subtext “Saturated and trans fat? No. But replacing carbohydrates with unsaturated fat could lead to a longer, healthier life.”
We’ve talked before about Walter Willett, chair of the Harvard School of Public Health’s nutrition department and a leader in the fight against trans fats. He was also instrumental in the drastic recent overhaul of the government’s food pyramid. Well, Willett says when it comes to chicken, go ahead and leave the skin on! “A little bit of chicken fat isn’t such a bad thing” and “besides, cooking chicken with the skin on makes it taste a lot better.” You better believe it – the next time I have fried chicken the skin stays on!
The Harvard article contains a very interesting table showing the percentages of saturated fat, trans fat, monounsaturated fat and polyunsaturated fat in various oils and fats. Chicken fat is 27% saturated, 41% monounsaturated and 31% polyunsaturated fat. It contains 0% trans fat. Compare that with beef fat, with 39% saturated, 8% trans, 49% monounsaturated and just 3% polyunsaturated fats. In other words, chicken fat is over 70% “good” fat while beef fat is split roughly half and half between “good” and “bad” fats.
I’m certainly not a nutritionist; so don’t follow my switch to eating the chicken skin without doing some research of your own on the subject. There was an excellent article in last Sunday’s New York Times magazine section by Gary Taubes. Taubes, who also wrote the book “Bad Science” debunking cold fusion, looks into the matter of “bad science” in the field of medicine and nutrition. I also heard Taubes being interviewed by Brian Lehrer this week on WNYC, New York’s Public Radio station. Taubes also has written a book on the subject that will no doubt stir up considerable controversy. He specifically details the problems involved in interpreting epidemiological data from studies such as the Nurses Health Study, a long running project in which my wife is one of the thousands of participants.
The Times article is much too detailed for me to cover it here. Just a quick example of one area he discusses in some detail – Hormone Replacement Therapy, HRT. Women of postmenopausal age are quite familiar with the early recommendations that HRT would help them cope with such things at hot flashes and would also protect against heart attacks. Later, of course, it was found that HRT seemed to promote heart attacks on prolonged use. Taubes discusses how such conflicting results can be obtained by not considering all the possible factors that can affect the results in studies of groups of individuals.
On the radio program, for example, there was a question concerning the well-known view that the Japanese have fewer heart attacks and lower rates of certain types of cancer due to their lower consumption of fats and their diet rich in fish. The question raised was whether anyone had considered that their better health regarding heart attacks might be due to the Japanese eating less sugar? Not having seen the book, whose title I didn’t catch, but having read the Times article, I would recommend either as being thought provoking inquiries into how easily dubious conclusions can be drawn from what seem to be sound scientific studies.
Finally, back to the chicken. The September 17 Newsweek had an article by Babak Dehghanpishen and John Barry titled “Brainiac Brigade”. The article concerns the very impressive group of military experts assembled in Baghdad by General Petraeus to try work on a strategy to handle the mess in Iraq. In March, the 20-member team got together in Baghdad, working 14-hour days. According to the article, a strange ritual was performed every day at 9:00 PM. A recording of the “Chicken Dance” was turned on and individuals would pick up things from their desks such as stuffed SpongeBobs, rubber chickens and rubber hand grenades and throw them into the air! Promptly at 9:10 PM the ritual stopped and it was back to work.
I’m wondering if one of them didn’t receive the same card my wife received and decided that they needed a respite from their very serious deliberations. I know I hadn’t had such a good laugh in weeks as when I opened the card and I hope that the “Chicken Dance” does the same for those folks in Iraq.
