Eating Kale, among other things

Tuesday, June 1st, 2010

Our friend Maggie sent me an email copy of "HEALTHbeat" (I'm putting titles into quotes today as my computer seems to have developed an aversion to italics), a Harvard Medical School publication. It's free on the Web and I signed up to get it regularly. This edition happened start with "Advice to women about supplements-use selectively." and my wife read that with great interest. I ordered two of their print publications, one for women over 50 and one on losing weight and keeping it off. I also sent them an email about what I think was a typo about the recommended vitamin D dosage.

Anyway they talked about nutrient-dense foods as being the best way to get many things we need in a synergistic fashion, which might turn out to be the more effective way as well. I looked through their list which included lots of foods we already eat in our high-fruit-and-vegetable, low-red-meat diet. Among the choices were avocados, bell peppers sweet potatoes, low-fat yogurt, peas, various nuts, salmon and chicken.

So far it sounded like a typical meal at our house. Then Lynnette, to whom I was reading the list, said, "We don't eat kale very often."

That intrigued me, so I went to an older book we frequently consult, "Food" by Waverly Root. The subtitle of this 1980 tome is "An authoritative visual history and dictionary of the foods of the world" and Mr. Root wasn't kidding. Sometimes he'll spend four pages on the histroy of a particular food item. If you ever run across a copy, I'd suggest buying it; we love this book. We also recently found "The New Food Lover's Companion" (the 2007 4th edition) by Sharon Tyler Herbst and Ron Herbst which had a paragraph on kale.

It's a member of the cabbage family, low in calories, high in vitamin C and calcium, and eaten more in Europe than in America, where it's been made into so-called pot greens. My copy of Barbara Kafka's great book, "Microwave Gourmet" gave me a way to cook kale and we'll try some soon.

But back to the Harvard Medical School advice. They appear to think women in America are taking too many multivitamins and that those haven't given all the benefits they've been touted to offer. Their publication for seniors does suggest taking one, but only one such pill a day. They do want you to try some of the foods I mentioned instead (there are more on their list) and to get some extra vitamin D.

We both take one senior vitamin pill a day (which has 125% of the daily recommended vitamin D dose), some calcium, B12, and vitamin C. They'd have us cutting back on some of that, but I'll read more before I do; nothing we're taking seems to offer a risk, as some preliminary studies show may be there for excess vitamin A and E, folic acid and beta carotene. Those studies, Harvard notes, "warrant further studies."

Nuts to you (and to me too)

Tuesday, May 11th, 2010

I just read an abstract in the My 10, 2010 edition of the Archives of Internal Medicine, having had my curiosity tweaked by a short piece in today's Wall Street Journal. There's a reason I always want to check the source material in the medical literature. When I was a Nephrology research fellow and attended on the clinical service a few months a year, a former patient came to me and asked if I'd read a chapter from a book his father, who had an unusual kidney disease, wanted to follow advice from. The book was written by a famous lifestyle guru and the writing and references cited were quite impressive. My patient knew that my boss was a field editor for two peer-reviewed research journals and that I, therefore, as part of my duties, critically read a half dozen articles a week prior to their being accepted (or rejected) for publication.

I picked twenty articles from the pertinent chapter and then went to the medical library. The book's author had claimed they all supported her concepts of what kidney patients should do. But, after reading them carefully, I concluded that not a single article had said what she claimed it did. Lesson learned and retained.

So the WSJ article talked about the health benefits of eating nuts, specifically tree nuts like walnuts, almonds, hazelnuts, macademia nuts, pistachios and also peanuts (which turn out to be a legume). They mentioned a series of studies on the subject.

In this case, when I found data on the lead researcher, an Internal Medicine physician who heads a deptament at a California university, I saw that he had a longterm interest in nuts and had pooled data from 25 nut consumption trials done on subjects of both genders, who were not taking any medication for elevated lipids or had normal lipids to start with.

The short form of the study's results would be eating nuts is good for you, can reduce your blood fats, if, and this is a big if, you're not obese to start with.  More nuts, roughly 2.4 ounces a day, led to better results than lesser amounts.

So I went to our big chest freezer, found a sack of walnuts and one of almonds, and we will start regularly adding nuts to our daily diet.

What's the FDA up to now?

Tuesday, March 9th, 2010

The Wall Street Journal published two interesting articles last week that may, in one case, apply to the world of health and diet and, in the other case directly applies. The first said the FDA's Office of Criminal Investigations should be more active. But, it also mentioned that an appellate judge had reversed a case ruling from a lower court where the FDA had charged a food wholesaler with misbranding the labels on their food product.

Hmm, on the one hand the FDA announce s(they did so in a letter to a senator) they will increase their prosecution of food industry executives, but one of their officials said they will do so with considerable thoughtfulness. The article itself shows why they have to, since their 2007 case got reversed.

The other article said the agency has warned a number of food and beverage makers that they must stick to government labeling requirements. They're particularly concerned about unproven health-benefit claims that don't help us as consumers decide which foods are healthy and which aren't.

Good so far, but I want to see this in action. While walking down the aisles of our favorite supermarket, I've see cereals I wouldn't dream of eating be labeled "a healthy choice" and that's just the beginning. Another example is "no trans fat" in products that still have lots (I define this as >4) grams of saturated fat per helping. One ice cream "snack" mentioned has 20 grams of saturated fat per serving.

The proof is in the pudding; I'll be happy if the FDA does crack down on labeling, but in the meantime I'll continue to read labels carefully and to do most of my supermarket shopping in the outer ring where the fruits and vegetables (and dairy products) are.

How to exercise when you can't really exercise

Tuesday, January 19th, 2010

We just spent a long weekend at the YMCA camp at Estes Park; it was a working vacation for me as I was away from the phone and email, but had a major project that would take lots of time. I had hoped to snowshoe each day, but we found out there was no nearby snow to speak of and Lynnette came down with a cold and didn't want to do anything strenuous.

So that was last Friday through Monday and today I had to drive to an appointment in Denver and then had a Symphony Board meeting. In any case I wasn't going to be able to get in my usual two plus hours at the gym.

We all have this kind of time, one where our best intentions are to get some good exercise in, but work or meetings or other scheduled events get in the way. We can either shrug our shoulders and say, "Well, I'll wait for another day," or we can do something else.

Each of our days in the mountains, we took a walk for thirty to sixty minutes a day. Today, between my drive back and forth to Denver and my two-hour board meeting,  I got in twenty minutes on the recumbent bike at our gym. I didn't get as much exercise as usual or as much as I would have liked to, but I at least got some.

In the case of the YMCA trip, I was able to break up time in front of my laptop with some quality time in the outdoors and to spend time in a shared activity with my wife. Today, I really had to squeeze in the gym time, but I felt refreshed afterwards and ready to cope with a board meeting.

Tomorrow I only have two meetings to attend, one between four and five PM and the other in the evening. I'll get up and go to the gym early and get back in my usual pattern.

I'm happy that I found some way to burn a few calories, spend quality time with Lynnette and break up what otherwise have felt like days of straight toil, with no time for fun. Exercise for me has become a tonic; afterwards I always feel energized and uplifted.

Try to find some time in your own day to get away from your desk or your computer or whatever occupies your time. be creative and look for new ideas on how you can take even short periods for exercise. I think you'll feel better and those small amounts of calories burned add up in the long run. If you're trying to lose weight, fifty calories a day translates into five pounds a year.
