Book Review: The Miami Mediterranean Diet
The Mediterranean diet is an important part of any brain health program. A number of studies have shown that people who follow the Mediterranean diet have less chance of having a heart attack, and that changing to the diet can reduce risk for another heart attack. Consistent with our increasing appreciation of the relation of heart and brain risk factors, at least one study has shown that people who follow the Mediterranean diet more closely have a lower risk of being diagnosed with Alzheimer’s disease.
Just that may be enough to have you ready to try the diet, but you might wonder what it is and what you’re supposed to eat. That’s where Dr. Michael Ozner’s book comes in. Dr. Ozner is a cardiologist in Miami, Florida, and says that he has been using the diet to treat his patients for more than 25 years. The book includes clinical vignettes in which patients describe their experiences with the diet and how it has helped them. Although Dr. Ozner recommends the often-unpopular practice of counting calories, people who follow the diet may find that they can eat more and still lose weight because of the diet’s emphasis on low-glycemic index foods, fresh fruit and vegetables, and whole-grain breads and pastas.
In clear language Dr. Ozner lays out the reasons why you should be interested in the diet. He gives you an overview of the studies that have shown that people who follow the diet have lower risk for heart disease, and explains why. You may note that many of the elements of the Mediterranean diet have anti-inflammatory and anti-oxidant effects, making it similar in this respect to Dr. Andrew Weil’s anti-inflammatory diet.
But the book has lots more than just a description of the why the diet is important. It also has a complete 14-day diet plan and a wide selection of recipes that any cook can use to make the diet not just healthy but delicious. My favorite section of recipes is the one for pizzas. There is also a section with a number of recipes for desserts that are high in flavor and low in fat.
Overall, this is a very useful book that will help you understand the importance of the Mediterranean diet and will help you get started in following it.

Mindfulness meditation as practiced over a long period by experts makes clear changes in someone’s brain function. But what about those of us who don’t have a few years to sit in a monastery in the Himalayas? A new study shows that even brief meditation practice can improve attention.
Researchers at Wake Forest University studied whether just four days of training (at just 20 minutes a day) could make a difference in participants’ mood, energy, and cognition. Undergraduate students (average age 22 years) either participated in the meditation sessions or spent a similar amount of time sitting quietly and listening to an audio book.
Participants in the meditation condition showed decreases in anxiety and improvements in several mental processing tasks compared to those in the audio book group. The meditators’ performance on one aspect of a working memory task (how many answers they got correct in a row) suggested that they may have improved their attention.
This is a small and very preliminary study that extends others’ work on meditation and the brain.It shows that even brief meditation practice can make a difference. you don’t have to be a Buddhist monk to learn to still your mind and pay better attention. Paying attention may be one of the most important things you can do to improve your brain’s functioning.

I saw an interesting blog post yesterday evening on the site of the Huffington Post about the potential benefits of meditation – or at least about what one woman thinks might be the benefits. Priscilla Warner writes about the contrast between Tibetan monks’ apparent calm, evident even on brain scans, and her own anxiety disorder. Ms. Warner says that she suffers from panic disorder, a severe form of anxiety in which a person can have multiple anxiety attacks every day, even in the middle of the night. Her post is titled “I Want the Brain of a Monk” Although most people don’t suffer from anxiety this severe, many people have symptoms of anxiety. And research has consistently shown that higher levels of anxiety are related to more memory problems.
What’s the relation to brain fitness? In my brain fitness class, I often mention the usefulness of meditation in helping reduce stress and anxiety, both of which have negative effects on memory. You don’t have to go to Tibet to get the benefits of meditation. If you simply take 10 minutes several times a day to break in to the ongoing rush of getting things done, you’ve made a start. Use those 10 minutes to sit quietly, relax your muscles, and breathe deeply.
If you do that every day for two weeks, I think you’ll notice that you feel calmer and better able to focus. And if you’re better able to focus, you will be better able to pay attention and remember things.
Although many people are excited about the potential for using computers to train their brains, we shouldn’t forget that other techniques have been used to the train the brain for many centuries. I’m thinking about the large number of techniques for meditation. While free computer software still requires an investment in a computer, meditation only asks you to sit or lie quietly and focus your mind.
A recently-published study shows parts of the brain in long-term meditators are larger than the same parts of the brain in people who don’t meditate. The article by Eileen Luders and her colleagues appeared in a recent issue of the journal Neuroimage (Vol. 45, No. 3, pp. 672-678, April 15, 2009). The study showed that portions of the orbitofrontal cortex and the hippocampus were larger in persons who had been regular meditators for 5 or more years. The study is interesting because the parts of the brain that were larger are often thought to be important in helping people keep themselves emotionally balanced.
A number of strategies are likely to be helpful for meditators. There has been a great deal of interest over the last several years in mindfulness meditation. Researchers have studied how it can be used in reducing anxiety and depression. Mindfulness is based on Buddhist meditation (for a brief article, click here) but you don’t have to be a Buddhist to practice meditation. In fact, one of the most important persons who has promoted mindfulness is Jon Kabat-Zinn, a researcher at the University of Massachusetts. You can see a video presentation by him on YouTube by clicking here.
