The Instinct to Heal by David Servan-Schreiber

Depression and anxiety seem to be the new defining diseases of our age, especially in the West. These disorders, and even severe stress, can affect our health as much as smoking or obesity.

 French psychiatrist David Servan-Schreiber notes that drugs and talk therapy are not especially effective, though the side-effects can be serious. The operating theory behind antidepressant drugs may simply be wrong.

 Dr. Servan-Schreiber suggests we look elsewhere for solutions to depression. The roots of depression are in the emotional brain, rather than the thinking brain, the body and the interaction between them.

 Our brain is layered, an as you go deeper inward, you get to older structures similar to other life forms: first those similar to other primates, then to mammals and finally to reptiles. The wordy, analytical, thinking part of the brain is the newest outer layer, the neocortex. Anxiety and depression are more strongly linked to the inner parts of the brain, which is emotional, image-oriented and much more closely linked to the operations of the body.

 One aspect of the brain-body connection is the heart. The heart has a bundle of nerves associated with it that are practically a simple brain itself, and this heart-brain has a direct connection to the emotional brain in the head. Our emotional and physical states are closely tied this way. Servan-Schreiber discusses techniques related to heart coherence, the variation of heart rate in a regular patter, that can be calming to the heart and brain and put is in a relaxed, restorative mode. His book includes instructions on a type of meditation for increasing heart coherence.

 He also talks about a technique that uses eye movements similar to those that occur while we dream to help the emotional brain process trauma, called eye movement desensitization and reprocessing (EMDR). This therapy will require a trip to a psychiatrist or psychologist, but for the right patients it can provide quick results.

 There is the suggestion that some cases of depression can be a symptom of disease or other issues in the body, especially inflammation. One of the things one can do deal with this type of depression is to get more Omega-3 fatty acids. These can help improve the function of the brain by improving the coating on brain cells. Depression seems to be more prevalent in countries where the typical diet is lower in Omega-3. Exercise can also improve depression and anxiety, especially when it is done regularly; three times a week for 20 minutes is enough to see a benefit.

 In addition, relationships and community are important to mental health and a sense of wellbeing. The quality of ones relationships can have a great impact on physical and mental health. Over the last few decades, people have come to have fewer and shallower relationships and less connections to community and purpose. Servan-Schreiber’s advice on this particularly focuses on ways to communicate that resolve conflicts and build empathy.

 Depression and anxiety are complex. Servan-Schreiber provides a suite of options for treating it. One of these may be helpful along, and some may need to use various ones in combination. In any case, there are things you can do, especially with the aid of a physician or psychologist, to make things better.

The Healthiest Diet on the Planet by John McDougal

I previously reviewed a couple of books on low-carb diets. Perhaps it is time for a dissenting opinion. Physician John McDowell argues for a low-fat vegan diet in The Healthiest Diet on the Planet.

The crux of the argument is the inversion of that made by some made by low-carb advocates, especially those who promote nearly carnivorous paleo diets. McDougall proposes that the primary diet of our ancient ancestors was plant-based, and that especially included energy-providing starches; he even refers to his picture of the ideal diet as “starchitarian.” He points to those parts of the world where people still eat their traditional diets and have low occurrence of obesity and associated diseases. They eat a lot of whole grains or potatoes along with vegetables and fruit; they eat little meat. It makes sense to me that this would be a natural diet for humans. In much of the world, foods from plants would have been much more widely available most of the year with much less effort and danger. Meat was probably a great calorie supplement to an otherwise lean diet, but it would not have been a reliable source of food for every meal, nor is it amenable to storage or preservation.

Another appealing aspect of the McDougall plan is it simplicity. In The Healthiest Diet on the Planet, he offers a green-yellow-red light approach to what to eat, what to eat with caution and what to avoid. The diet consists mainly of starchy foods: whole grains, potatoes, sweet potatoes and beans. It also includes vegetables and some fruit. Some foods, such as nuts, avocadoes and fruit juices, can be eaten in small amounts; they are a concern because they include a lot of fat or sugar. Finally, avoid animal products (meat, eggs and dairy) and extracted vegetable oils. McDougall admits that it is unusual of natural human diets to be completely devoid of meat, so I suspect it would be okay for someone to eat meat once in a while.

I haven’t tried it any more than I have tried a low-carb diet. It certainly seems easier. It is also likely to be less expensive.

Like many diet books, this one includes recipes. Coauthor Mary McDougal contributed the recipes.
