 Wurst und Käse Salat. Bring on the cheese! First off, I hope all of you and your families had a wonderful Thanksgiving. Mine was really nice: delicious food and great conversation with family and dear friends.
I've been wanting to write a post like this for some time now. My intention is not to criticize other people's beliefs but rather to explain my own and why I hold them. Looking over a number of "Paleo Thanksgiving" menus prompted me to finally address my ambivalence about Paleo, Primal, Weston A. Price Foundation, and other "real food" ways of eating. I know that several people who read this blog identify with one or more of these ways of eating. Please keep in mind that I strongly favor a whole foods approach over a diet containing processed foods. I'm a proud member of Real Food Dietitians, and I recently became a Primal Docs featured member. However, I think carbohydrate restriction is ultimately more important for people trying to manage diabetes, prediabetes, obesity, metabolic syndrome, and PCOS. Diabetes, Hyperinsulinemia, and Insulin Resistance There's a lot of convincing research supporting very-low-carbohydrate diets for people with Type 2 diabetes, metabolic syndrome, and polycystic ovarian syndrome. I'm planning a blog post on insulin resistance and hyperinsulinemia in the near future, but suffice it to say that many, if not most, overweight people have impaired insulin sensitivity, resulting in elevated blood sugar and insulin levels that cause hunger, damage blood vessels and nerves throughout the body, and promote fat storage. Keeping carb intake very low (less than 50 grams per day) will have a beneficial effect on insulin resistance and hyperinsulinemia in virtually everyone, whereas a diet containing twice or three times as much carbohydrate may work for a portion of this population, but most will need to restrict carbohydrates further to lose weight and achieve healthy blood sugar and insulin ranges. In general, the works of Drs. Steve Phinney, Jeff Volek, Eric Westman, Richard Feinman, Michael Eades, Richard K. Bernstein, and other low-carbohydrate researchers are more exciting and convincing to me than authors who classify themselves as Paleo or Primal. People with Type 1 diabetes or normal weight individuals with blood sugar issues (I'd place myself in the latter category) will also benefit from keeping carbohydrate levels very low. I followed a Primal, moderately low-carb (100 grams or so per day) diet for a while but continued to have postprandial blood sugars over 160 and sometimes as high as 200. Only when I began restricting carbohydrates to 15 or fewer grams per meal did my blood sugar response normalize, and it's remained this way for the past year and a half. Dairy I realize dairy is controversial in the Paleo and Primal community due to its lactose content, insulin-stimulating properties, and potential for allergies, but I personally consume quite a bit of it without any problems. In fact, I have Greek yogurt, cheese, sour cream, and/or cream every day and maintain a healthy weight. While there are certainly people with legitimate reasons to avoid dairy (such as true allergies or hypercalcemia), I think many others will do okay with it. If you have other symptoms that clear up when you eliminate dairy, then obviously you shouldn't eat it. I understand the WAPF's position on the benefits of raw milk, but I disagree that pasteurized, homogenized dairy products are inherently bad. My parents are from Switzerland and grew up on pasteurized milk products, as did their parents, and continued consuming them throughout their lives. They're now in their 70s, active, and in excellent health, and I know there are many others like them. While raw milk may contain more nutrients and allow for better absorption of fat-soluble vitamins, I think pasteurized milk provides benefits as well. Grains Here's where I may lose some of my readers (if I haven't lost you already). There was recently a very successful Gluten Summit, and two intelligent MDs, Drs. Davis and Perlmutter, have written books detailing the devastating effects gluten can have on susceptible individuals. But not everyone is gluten sensitive! I avoid grains because of their carb content and I don't really mind not eating them, but there are other low-carbers who consume low-carb bread, wraps, etc., without any problems. Dr. Steve Parker's Low Carbohydrate Mediterranean Diet allows grains for those who tolerate them. The Paleo Thanksgiving yam and sweet potato recipes I saw online contain a lot of carbohydrates. Eating a small amount would be fine, but many people tend to eat larger portions of foods they're told are healthy. I'm not saying that grains are good for you, but to be honest, I'd rather someone with diabetes eat a forkful of stuffing (about 3 grams of carb) than a cup of sweet potatoes (37 grams of carb if plain). Sweeteners Another controversial area among Paleo/Primal/WAPF devotees is sweeteners. Honey or pure maple syrup is often recommended as an alternative to table sugar. However, these items contain more carbohydrate per serving than sugar does, so they're not a good choice for people with diabetes or insulin resistance. Green leaf stevia is recommended as an option for those who need to limit carbohydrates. But have you tasted stevia? It's got an interesting flavor (reminiscent of anise, in my opinion), but it really doesn't work well as a sweetener for all types of food. I rarely use any sweetener at all, but when I do bake occasionally, I use erythritol, a sugar alcohol that isn't absorbed by the body and tastes very similar to sugar. Some have argued that erythritol is a processed product made from corn, but I think people with issues related to glucose intolerance would be better off consuming it -- or even saccharin -- instead of "natural" sweeteners, including fruit juice. Again, it's best to avoid all types of sweeteners except in limited amounts. I do eat a square of 85-90% cacao dark chocolate a few times a week. It's sweetened with sugar but only has about 2 grams of net carb. Pastured and/or Organic As a former vegetarian for ethical reasons, I strongly support raising animals as naturally and humanely as possible. I would prefer to always eat pastured, organic, or naturally raised meat, dairy, and eggs, and most of the time I do, at least at home. But there are many people who can't afford to eat this way on a daily basis. I've written about this before, but I feel even more strongly now that people on limited budgets shouldn't be made to feel that they're jeopardizing their health if they can't buy organic food. I've seen individuals on low-carb forums say that they have to quit eating low carb because it's too expensive. But there are lots of ways to eat low carb without spending a lot of money (also Google "low carb on a budget"). Replacing higher-carb items with conventionally raised animals, eggs, and cheese can have a profound positive effect on blood glucose and insulin levels, as well as weight. And at the end of the day, that's the most important thing. I hope I didn't offend any of the people I respect yet differ with on this issue, but I wanted to make clear where I stand. If folks with diabetes or weight issues can combine "real food" and low carbohydrate intake, this is ideal. But I'll always place carb restriction as the top priority for them because I truly believe it's the key to improving their health. References 1.

This weekend, November 11-14, the Weston A. Price Foundation (WAPF) is holding its 12th Annual Wise Traditions Conference in Dallas. As has become my pattern with events I'd love to attend, I learned about this one too late. After taking a look at the list of distinguished speakers scheduled to present, I'm wishing more than ever that I were there. Anyone who has seen the movie Fat Head (if you haven't seen it yet, I highly recommend watching it) will surely remember the discussion about the healthful aspects of fat and cholesterol by WAPF co-founders Sally Fallon and Mary Enig, PhD.
For those unfamiliar with the WAPF, it is a nonprofit organization whose mission is to promote the research of Weston A. Price, a dentist who in the 1930s-40s performed extensive studies of several diverse societies worldwide in an attempt to discover why some people thrived while others in nearby regions suffered from various diseases. Not surprisingly, the healthfulness of one's diet was found to be the prevailing factor. High intake of whole plant foods including fruits and vegetables rich in enzymes, unprocessed or raw animal foods, and liberal amounts of butterfat and other saturated fats were determined to be highly health promoting by Dr. Price. He photographed families who were isolated from civilization and consumed traditional diets as well as nearby "civilized" groups who consumed "modern" ( processed) foods, and the differences in the quality of their teeth and facial bone structure were striking. Dr. Price discovered that cavities and crooked or crowded teeth were due to nutrient deficiencies and that the state of one's teeth closely mirrored the health of the rest of the body. Now, I know this website is called Low Carb Dietitian. The WAPF is not really advocating a low-carbohydrate for most people, although they certainly advise against consuming all refined sugar and processed grains and suggest that people people with diabetes or sensitivity to carbohydrates cut down on them. But I feel the emphasis on whole, unprocessed, sustainably raised foods rich in vital nutrients is ultimately the most important factor in achieving optimal health for all of us. It's very easy to follow WAPF principles and continue a low-carb lifestyle by simply foregoing any problem foods (these are different for each of us depending on our unique genetic makeup, physiology, and presence of various disease states). Below are ten WAPF recommendations I feel we can all benefit from: 1. Daily use of cod liver oil as a rich source of vitamins A and D 2. Choosing butter instead of margarine (even "healthy" spreads) 3. Using small amounts of natural sweeteners (if at all) rather than artificial sweeteners 4. Eating fermented foods 5. Consuming grass-fed meat and pastured eggs 6. Eliminating soy 7. Consuming bone broth regularly 8. Eating organ meats 9. Consuming raw and/or organic dairy 10. Limiting or eliminating caffeine So am I doing all of these things? Not quite, but I am close. I haven't yet embraced organ meats. I only recently began eating meat again, and I've never liked liver (and have never even tried any other organ meats), so I'm not in a hurry to try this, although the health benefits are huge. I also haven't tried raw dairy yet, mostly because it's difficult to find. As far as caffeine, I drink one weak cup of green tea every morning. For those interested in learning more about Weston A. Price and his foundation, please check out the WAPF website. Also, I just finished one of the best books I've read all year, Nourishing Traditions: The Cookbook that Challenges Politically Correct Nutrition and the Diet Dictocrats, by Sally Fallon and Mary Enig, Ph.D. It's more than 10 years old, but it's packed with highly relevant information about the benefits of traditional diets and contains hundreds of recipes along with interesting sidebars by some of the leading authors and researchers on whole foods and traditional diets. On a final note, there are a number of registered dietitians who belong to a WAPF Yahoo group that is trying to promote change within the American Dietetic Association. One of the group's primary goals is to sever ties with sponsors like Coca-Cola, PepsiCo, Mars, Hershey, and General Mills, and get back to recommending real, nutrient-dense foods like butter, eggs, meat, cheese, etc. I'm very happy to say that I'm a member of this group of RDs and am hopeful that our ranks will continue to grow so that we can ultimately provide education that leads to better health for our own society. |
