Are the Boston Red Sox Malnourished?

Posted by on October 11, 2010 45 comments

Last Thursday’s post was mainly concerned with Abby’s bone injury that refused to heal. I noted that four nutrients – vitamins C, D, and K2, and magnesium – were essential for bone health, and that deficiencies could have contributed both to Abby’s injury and her slow healing.

Today’s post is about another group of people who frequently break their bones and don’t heal well:  the Boston Red Sox.

Injury-Prone Sox

Those who follow baseball may know that a promising 2010 Red Sox season was sabotaged by a rash of broken bones:

  • Centerfielder Jacoby Ellsbury missed 144 games with hairline fractures in four ribs; they failed to heal properly and re-fractured months after the initial injury.
  • Second baseman Dustin Pedroia missed all but two games after breaking his foot June 25.
  • Catcher Victor Martinez missed a month with a broken thumb.
  • Backup catcher Jason Varitek played just five games after breaking his foot on July 2.

There were muscle and joint injuries too, but let’s stick to bones.

Is it possible the Red Sox players are suffering from micronutrient deficiencies?

The Red Sox Hire a Dietitian

A few years ago the Red Sox hired a professional dietitian to advise their players: Tara Mardigan of the Dana-Farber Cancer Institute.

Ms Mardigan is a lovely woman, a marathoner and former gymnast, with a charming personality that shines through in radio interviews. She obtained her position with the Red Sox after meeting Red Sox president Larry Lucchino at a charity breakfast.

But what is her diet advice, and which players are taking it? I found a hint about the latter question in an interview in the student newspaper at Tufts University’s Friedman School of Nutrition Science, where Ms Mardigan studied:

I stopped working full-time at Dana-Farber to accommodate working with the Red Sox, and luckily they have a great relationship with the team so I was able to reduce my hours.  I also work with the Red Sox’s minor league teams, the Lowell Spinners, Pawtucket Red Sox, and Portland Sea Dogs. This is where I really make changes.  I work with young guys who are interesting in learning about how nutrition can improve their performance.  They are hungry to get to the big leagues. It’s great to see them move up into the major league, and then become someone like Jacoby Ellsbury (Left Field/Center Field) who is now well-versed in nutrition.

Uh oh! Jacoby Ellsbury, who managed only 18 games in 2010, whose bones break on incidental contact and whose hairline fractures won’t heal in six months, is the dietitian’s prize pupil?

The Dietitian Advises Avoiding Supplements

The Friedman School interview didn’t tell us much about Ms. Mardigan’s dietary recommendations, other than that she opposes most nutritional supplements:

I try to get them to choose food before supplements, and only supplements when necessary. Athletes are vulnerable and think [supplements] are well made and well regulated, and they are shocked when they find out they are not.

Those who have read our book know that we have a chapter titled “Why Moderns are Malnourished” which explains why modern agriculturally-produced foods and treated water don’t provide enough micronutrients, and why supplements are needed to optimize health.

Among the micronutrients for which supplementation is most needed are vitamin K2 and magnesium – two crucial nutrients for bone health.

What Is Her Diet Advice?

To get an idea of what diet she might be recommending, I looked at the Dana-Farber nutrition team web site, and was surprised to see this graphic illustration of their “Optimal Diet plan for cancer survivors”:

Yikes! No fats, and no mention of healthy plant foods like starchy tubers. A quarter of the diet is toxic grains and the protein may be derived from toxic legumes. It looks like roughly 70% of calories come from carbs and 25% from protein.

Later in the page they suggest such omega-6-rich oils as soybean oil, canola oil, flaxseed oil, wheat germ oil, and walnuts – all eliminated on the Perfect Health Diet.

It seems Ms Mardigan has recommended a similar diet to the Red Sox. From the Dana-Farber site:

On staff with the club since January 2006, she attends most home games to meet with players and make sure grilled chicken, steamed vegetables, and other healthful options are available in the team dining room.

Vegetables and lean protein, just like the Dana Farber diet. Another clue from this interview:

“My diet is very restricted right now, but Tara has been wonderful at helping me figure out what I can eat, like certain thick-skinned fruits and soy products,” says Anne Forgit, a leukemia patient and recent bone marrow transplant recipient.

Soy products. As readers of our book know, this is a highly toxic food.

Ms Mardigan does have a personal home page. The only clues I found there to her diet advice reside on her “Resources” page, where she recommends Michael Pollan’s In Defense of Food and  Dr. Walter Willett’s Eat, Drink, and Be Healthy. Pollan is a journalism professor who has made a career attacking industrial agriculture, and has likened the Atkins diet to an eating disorder. He seems to avoid specific diet advice, but it looks like he favors grains and omega-6-rich plant fats over animal fats. Dr. Willett is mentioned in our book, where we object to his opposition to coconut oil and saturated fat. He is a promoter of polyunsaturated fat and whole grain consumption.

If this is what Ms Mardigan is recommending to the Red Sox, it’s no wonder their bones are breaking:

  • Grains are toxic to bones. Wheat, oats, and other grains induce rickets, a softening of the bones that leads to frequent fractures. (This is discussed extensively in our book, and has been known since Mellanby’s original experimental investigations into rickets in dogs [1].)
  • Omega-6 polyunsaturated fats reduce bone mineral density. [2]

The Missing Nutrients

So the Red Sox players are being recommended a diet that is highly toxic to bones. But what about the key bone nutrients?  Are they lacking in those as well?

The answer is almost certainly yes. The fat-soluble nutrients are critical to bone remodeling, and it seems the Red Sox diet is completely lacking in vitamin K2.  Plant sources of vitamin K1 aren’t sufficient for bones, and animal sources of K2 seem to be excluded from the Red Sox diet.

Bone fracture rates are very strongly dependent on vitamin K2 levels. Most people are deficient, and supplementation with K2 reduces risk of vertebral fractures by 60%, hip fractures by 77%, and non-vertebral fractures by a remarkable 81%. [3]

If that happens on ordinary diets, the reduction in fracture rates would probably be even more remarkable on a K2-empty diet like the one that has been recommended to the Red Sox.

Conclusion

If a biomedical scientist were asked to contrive a diet that maximized the likelihood of bone fractures, the advice would be:

  1. Eat lots of grains to induce rickets.
  2. Eat vegetable oils and non-tropical fatty plants to reduce bone mineral density.
  3. Avoid animal and dairy fats to deprive the body of fat-soluble vitamins needed for bone mineralization, such as vitamin K2.
  4. Do not take nutritional supplements, in order to maintain a deficiency of bone nutrients.

It seems that this is precisely the advice that is being given to the Red Sox and their minor league players.

This year’s broken bones cost the Red Sox a chance at a World Series. The player who followed this diet advice most rigorously, Jacoby Ellsbury, lost a full season to bone fractures, and his injury history could cost him millions when he becomes a free agent next year.

As a lifelong Red Sox fan, I beseech the team to reconsider their diet advice.

Nutrients Are Needed to Heal Wounds and Injuries

Posted by on October 7, 2010 68 comments

Abby asked for suggestions to accelerate healing of her injuries. What should be done when a wound won’t heal?

More often than not, I think, slow healing wounds reflect nutritional deficiencies. Tissue regeneration is a nutrient-intensive process, and a lack of nutrients can radically slow it down.

Osteoporosis Epidemic Indicates a Widespread Deficiency of Bone Nutrients

Tissues are not static:  they are constantly broken down and regenerated. So just maintaining tissues requires a steady supply of nutrients.

Bone is particularly in need of certain nutrients: vitamins C, D, and K2; magnesium; and others. Unfortunately, the nutrients needed by bone are precisely the ones in which Americans are most deficient.

I believe that deficiencies in these nutrients are the main cause of the osteoporosis epidemic. Take vitamin K2. Most Americans are deficient in vitamin K2, which is needed for bone calcification. Non-vertebral fractures are five-fold more common in people with vitamin K2 deficiency. [1] The rise in fracture rate in women after menopause may be due to the fact that estrogen improves vitamin K2 status. [2]

Vitamin D is another nutrient critical for bone health. Bone mineral density peaks in the range 32 to 45 ng/ml. [3]

Vitamin C is a third nutrient necessary for bone health. Vitamin C is needed for collagen to form a meshwork that can then be mineralized by calcium, magnesium and other minerals. In the absence of vitamin C, bone is malformed.

Interestingly, cow’s milk has only one-fifth the vitamin C of human breast milk, and vitamin C is destroyed during pasteurization, so formula-fed babies before the days of vitamin C supplementation were prone to scurvy. Some believe that vitamin C and vitamin D deficiencies, not malicious parents, are responsible for “Shaken Baby Syndrome.” [4,5]

Vitamin Levels Determine the Success of Orthopedic Surgery

Today I read a press release about a study that found that 40% of all patients arriving for orthopedic surgery, and 52% of those coming in for trauma service, were deficient in vitamin D. Deficiency was defined as 25(OH)D levels below 20 ng/ml.

(We recommend keeping 25(OH)D between 35 and 50 ng/ml.)

What happened?  Those who had surgery with vitamin D deficiency failed to heal properly, while those who were vitamin D sufficient generally did well. Concluded the doctors:

“In the perfect world, test levels, fix and then operate,” said Joseph Lane, M.D., professor of Orthopedic Surgery and chief of the Metabolic Bone Disease Service at HSS, who led the study. “If you put people on 2,000-4,000 [milligrams] of vitamin D based on what their deficient value was, you can usually get them corrected in four to six weeks, which is when you are really going to need the vitamin D. If you are really aggressive right before surgery, you can correct deficient levels quickly, but you have to correct it, measure it, and then act on it.”

According to Dr. Lane, bone remodeling or bone tissue formation, a part of the healing process, occurs about two to four weeks after surgery. This is the critical stage when your body needs vitamin D….

“With arthroplasty, there is a certain number of patients that when you put in the prothesis, it breaks the bone adjacent to the protheses, which can really debilitate patients.” This could be prevented or minimized by rectifying vitamin D levels. Dr. Lane also explained that they now perform procedures where they grow a bone into a prosthesis without using cement. “In those people, it would be an advantage to have adequate vitamin D, because it matures the bone as it grows in, it is really healing into the prosthesis,” he said.

“The take home message is that low vitamin D has an implication in terms of muscle and fracture healing, it occurs in about 50 percent of people coming in for orthopedic surgery, and it is eminently correctable,” Dr. Lane said. “We recommend that people undergoing a procedure that involves the bone or the muscle should correct their vitamin D if they want to have an earlier faster, better, result. What we are saying is ‘wake up guys, smell the coffee; half of your patients have a problem, measure it, and if they are low, then fix it.'” [6]

Conclusion

If you have any sort of injury, make sure you are well nourished.

If an injury refuses to heal, consider it a red flag:  you are probably missing one or more crucial micronutrients. Take steps to identify the deficiencies and remedy them as quickly as possible.

A Sample Meal: Salmon and Mashed Sweet Potato

Posted by on October 5, 2010 50 comments

Marla is having trouble visualizing a 70% fat meal, and asked for a sample meal plan. I don’t have meal plans at the ready, but I do have some random food pictures, and this one shows a typical meal at our home. Click to enlarge:

The meal is salmon, vegetables (spinach, bell pepper, onion, carrot, and lemon slices), and mashed sweet potatoes. The salmon and vegetables were baked together with butter, because that’s an easy way to make vegetables. The sweet potatoes were mashed with butter and coconut oil.

Overall this meal is light in carbs: this is a reasonable amount of meat for a meal (we tend to the low protein side of the diet), but has only about 100 carb calories, so lower in starch than we like. But it is at least 70% fat, probably closer to 80% fat, in terms of calories. So it gives a reasonable idea what our meals look like.
