Can Vegans Have Strong Bones?

December 14, 2021 by Dr. Steve Chaney

When Is Supplementation Important?

Author: Dr. Stephen Chaney

Whole food, vegan diets are incredibly healthy.

They have a low caloric density, which can help you maintain a healthy weight.

They are anti-inflammatory, which can help prevent all the “itis” diseases.

They are associated with reduced risk of diabetes, heart disease, and some cancers.

Plus a recent study has shown that vegans age 60 and older require 58% fewer medications than people consuming non-vegetarian diets.

But vegan diets are incomplete, and as I have said previously, “We have 5 food groups for a reason”. Vegan diets tend to be low in several important nutrients, but for the purposes of this article I will focus on calcium and vitamin D. Vitamin D is a particular problem for vegans because mushrooms are the only plant food that naturally contain vitamin D, and the vitamin D found in mushrooms is in the less potent D2 form.

Calcium and vitamin D are essential for strong bones, so it is not surprising that vegans tend to have less dense bones than non-vegans. But are these differences significant? Are vegans more likely to have broken bones than non-vegans?

That is the question the current study (DL Thorpe et al, American Journal of Clinical Nutrition, 114: 488-495, 2021) was designed to answer. The study also asked whether supplementation with calcium and vitamin D was sufficient to reduce the risk of bone fracture in vegans.

How Was This Study Done?

The data for this study were obtained from the Adventist Health Study-2. This is a study of ~96,000 members of the Seventh-day Adventist Church in North America who were recruited into the study between 2002 and 2007 and followed for up to 15 years.

Seventh-day Adventists are a good group for this kind of study because the Adventist church advocates a vegan diet consisting of legumes, whole grains, nuts, fruits, and vegetables. However, it allows personal choice, so a significant number of Adventists choose modifications of the vegan diet and 42% of them eat a nonvegetarian diet.

This diversity allows studies of the Adventist population to not only compare a vegan diet to a nonvegetarian diet, but also to compare it with the various forms of vegetarian diets.

This study was designed to determine whether vegans had a higher risk of hip fractures than non-vegan Adventists. It was performed with a sub-population of the original study group who were over 45 years old at the time of enrollment and who were white, non-Hispanic. The decision to focus on the white non-Hispanic group was made because this is the group with the highest risk of hip fractures after age 45.

At enrollment into the study all participants completed a comprehensive lifestyle questionnaire which included a detail food frequency questionnaire. Based on the food frequency questionnaire participants were divided into 5 dietary patterns.

Vegans (consume only a plant-based diet).
Lacto-ovo-vegetarian (include dairy and eggs in their diet).
Pesco-vegetarians (include fish as well as dairy and eggs in their diet).
Semi-vegetarians (include fish and some non-fish meat (primarily poultry) as well as dairy and eggs in their diet).
Non-vegetarians (include all meats, dairy, and eggs in their diet). Their diet included 58% plant protein, which is much higher than the typical American diet, but much less than the 96% plant protein consumed by vegans.

Every two years the participants were mailed follow-up questionnaires that included the question, “Have you had any fractures (broken bones) of the wrist or hip after 2001? Include only those that came from a fall or minor accident.”

Can Vegans Have Strong Bones?

The results of this study were striking.

When men and women were considered together there was an increasing risk of hip fracture with increasing plant-based diet patterns. But the differences were not statistically significant.

However, the effect of diet pattern on the risk of hip fractures was strongly influenced by gender.

- For men there was no association between diet pattern and risk of hip fractures.

- For women there was an increased risk of hip fractures across the diet continuum from nonvegetarians to vegans, with vegan women having a 55% higher risk of hip fracture than nonvegetarian women.

The increased risk of hip fractures in vegan women did not appear to be due to other lifestyle differences between vegan women and nonvegetarian women. For example:

- Vegan women were almost twice as likely to walk more than 5 miles/week than nonvegetarian women.

- Vegan women consumed more vitamin C and magnesium, which are also important for strong bones, than nonvegetarian women.

- Vegan women got the same amount of daily sun exposure as nonvegetarian women.

The effect of diet pattern on the risk of hip fractures was also strongly influenced by supplementation with calcium and vitamin D.

- Vegan women who did not supplement with calcium and vitamin D had a 3-fold higher risk of hip fracture than nonvegetarian women who did not supplement.

- Vegan women who supplemented with calcium and vitamin D (660 mg/day of calcium and 13.5 mcg/day of vitamin D on average) had no increased risk of hip fracture compared to nonvegetarian women who supplemented with calcium and vitamin D.

In interpreting this study there are a few things we should note.

- The authors attributed the lack of an effect of a vegan diet on hip fracture risk in men to anatomical and hormonal differences that result in higher bone density for males.

- In addition, because the average age of onset of osteoporosis is 15 years later for men than for women, this study may not have been adequately designed to measure the effect of a vegan diet on hip fracture in men. Ideally, the study should have enrolled participants who were at least 60 or older if it wished to detect an effect of diet on hip fractures in men.

- Finally, because the study enrolled only white, non-Hispanic women into the study, it does not tell us the effect of a vegan diet on women of other ethnicities. Once again, if there is an effect, it would likely occur at an older age than for white, non-Hispanic women.

The authors concluded, “Without combined supplementation of both vitamin D and calcium, female vegans are at high risk of hip fracture. However, with supplementation the excessive risk associated with vegans disappeared.”

Simply put, vegan diets are very healthy. They reduce the risk of heart disease, high blood pressure, diabetes, some cancers, and inflammatory diseases.

However, the bad news is:

Vegan women have a lower intake of both calcium and vitamin D than nonvegetarian women.

Vegan women have lower bone density than nonvegetarian women.

Vegan women have a higher risk of hip fracture than nonvegetarian women.

The good news is:

Supplement with calcium and vitamin D eliminates the increased risk of hip fracture for vegan women compared to nonvegetarian women.

When Is Supplementation Important?

Much of the controversy about supplementation comes from a “one size fits all” mentality. Supplement proponents are constantly proclaiming that everyone needs nutrient “X”. And scientists are constantly proving that everyone doesn’t need nutrient “X”. No wonder you are confused.

I believe in a more holistic approach for determining whether certain supplements are right for you. Dietary insufficiencies, increased need, genetic predisposition, and diseases all affect your need for supplementation, as illustrated in the diagram on your left. I have discussed this approach in more detail in a previous issue (https://www.chaneyhealth.com/healthtips/do-you-need-supplements/) of “Health Tips From the Professor”.

But today I will just focus on dietary insufficiencies.

Most Americans consume too much highly processed fast and convenience foods. According to the USDA, we are often getting inadequate amounts of calcium, magnesium, and vitamins A, D, E and C. Iron is also considered a nutrient of concern for young children and pregnant women.

According to a recent study, regular use of a multivitamin is sufficient to eliminate most these deficiencies except for calcium, magnesium, and vitamin D. A well-designed calcium, magnesium and vitamin D supplement may be needed to eliminate those deficiencies.

In addition, intake of omega-3 fatty acids from foods appears to be inadequate in this country. Recent studies have found that American’s blood levels of omega-3s are among the lowest in the world and only half of the recommended level for reducing the risk of heart disease. Therefore, omega-3 supplementation is often a good idea.

Ironically, “healthy” diets are not much better when it comes to dietary insufficiencies. That is because many of these diets eliminate one or more food groups. And, as I have said previously, we have 5 food groups for a reason.

Take the vegan diet, for example:

There is excellent evidence that whole food, vegan diets reduce the risk of heart disease, diabetes, inflammatory diseases, and some cancers. It qualifies as an incredibly healthy diet.

However, vegan diets exclude dairy and meats. They are often low in protein, vitamin B12, vitamin D, calcium, iron, zinc, and long chain omega-3 fatty acids. Supplementation with these nutrients is a good idea for people following a vegan diet.

The study described above goes one step further. It shows that supplementation with calcium and vitamin D may be essential for reducing the risk of hip fractures in vegan women.

There are other popular diets like Paleo and keto which claim to be healthy even though there are no long-term studies to back up that claim.

However, those diets are also incomplete. They exclude fruits, some vegetables, grains, and most plant protein sources.

A recent study reported that the Paleo diet increased the risk of calcium, magnesium, iodine, thiamin, riboflavin, folate, and vitamin D deficiency. The keto diet is even more restrictive and is likely to create additional deficiencies.

And it is not just nutrient deficiencies that are of concern when you eliminate plant food groups. Plants also provide a variety of phytonutrients that are important for optimal health and fiber that supports the growth of beneficial gut bacteria.

In short, the typical American diet has nutrient insufficiencies. “Healthy” diets that eliminate food groups also create nutrient insufficiencies. Supplementation can fill those gaps.

The Bottom Line

Vegan diets are incredibly healthy, but:

They eliminate two food groups – dairy, and meat protein.

They have lower calcium and vitamin D intake than nonvegetarians.

They also have lower bone density than nonvegetarians.

The study described in this article was designed to determine whether vegans also had a higher risk of bone fractures. It found:

Vegan women who don’t supplement have a 3-fold higher risk of hip fracture than nonvegetarian women.

The increased risk of hip fractures in vegan women did not appear to be due to other lifestyle differences between vegan women and nonvegetarian women.

Supplementation with calcium and vitamin D (660 mg/day of calcium and 13.5 mcg/day of vitamin D on average) eliminated the difference in risk of hip fracture between vegan women and nonvegetarian women.

In the article above I discuss the importance of supplementation in assuring diets are nutritionally complete.

In short, the typical American diet has nutrient insufficiencies. “Healthy” diets that eliminate food groups also create nutrient insufficiencies. Supplementation can fill those gaps.

For more details about the study and a discussion of which supplements may be needed to assure nutritionally adequate diets, read the article above.

Are Vegan Diets Bad For Your Bones?

The Secrets To A Healthy Vegan Diet

Author: Dr. Stephen Chaney

Osteoporosis is a debilitating and potentially deadly disease associated with aging. It affects 54 million Americans. It can cause debilitating back pain and bone fractures. 50% of women and 25% of men over 50 will break a bone due to osteoporosis. Hip fractures in the elderly due to osteoporosis are often a death sentence.

As I discussed in a previous issue of “Health Tips From The Professor”, a “bone-healthy lifestyle requires 3 essentials – calcium, vitamin D, and weight bearing exercise. If any of these three essentials is presence in inadequate amounts, you can’t build healthy bones. In addition, other nutrients such as protein, magnesium, zinc, vitamin B12, and omega-3 fatty acids may play supporting roles.

Vegan and other plant-based diets are thought to be very healthy. They decrease the risk of heart disease, diabetes, and some cancers. However, vegan diets tend to be low in calcium, vitamin D, zinc, vitamin B12, protein, and omega-3 fatty acids. Could vegan diets be bad for your bones?

A meta-analysis of 9 studies published in 2009 (LT Ho-Pham et al, American Journal of Clinical Nutrition 90: 943-950, 2009) reported that vegans had 4% lower bone density than omnivores, but concluded this difference was “not likely to be clinically relevant”.

However, that study did not actually compare bone fracture rates in vegans and omnivores. So, investigators have followed up with a much larger meta-analysis (I Iguacel et al, Nutrition Reviews 77, 1-18, 2019) comparing both bone density and bone fracture rates in vegans and omnivores.

How Was This Study Done?

The investigators searched the literature for all human clinical studies through November 2017 that compared bone densities and frequency of bone fractures of people consuming vegan and/or vegetarian diets with people consuming an omnivore diet.

Vegan diets were defined as excluding all animal foods.

Vegetarian diets were defined as excluding meat, poultry, fish, seafood, and flesh from any animal but including dairy foods and/or eggs. [Note: The more common name for this kind of diet is lacto-ovo vegetarian, but I will use the author’s nomenclature in this review.]

Omnivore diets were defined as including both plant and animal foods from every food group.

The investigators ended up with 20 studies that had a total of 37,134 participants. Of the 20 studies, 9 were conducted in Asia (Taiwan, Vietnam, India, Korea, and Hong-Kong), 6 in North America (the United States and Canada), and 4 were conducted in Europe (Italy, Finland, Slovakia, and the United Kingdom).

Are Vegan Diets Bad For Your Bones?

Here is what the investigators found:

Bone density: The clinical studies included 3 different sites for bone density measurements – the lumbar spine, the femoral neck, and the total body. When they compared bone density of vegans and vegetarians with the bone density of omnivores, here is what they found:

Lumbar spine:

- Vegans and vegetarians combined had a 3.2% lower bone density than omnivores.

- The effect of diet was stronger for vegans (7% decrease in bone density) than it was for vegetarians (2.3% decrease in bone density).

Femoral neck:

- Vegans and vegetarians combined had a 3.7% lower bone density than omnivores.

- The effect of diet was stronger for vegans (5.5% decrease in bone density) than it was for vegetarians (2.5% decrease in bone density).

Whole body:

- Vegans and vegetarians combined had a 3.2% lower bone density than omnivores.

- The effect of diet was statistically significant for vegans (5.9% decrease in bone density) but not for vegetarians (3.5% decrease in bone density). [Note: Statistical significance is not determined by how much bone density is decreased. It is determined by the size of the sample and the variations in bone density among individuals in the sample.]

Bone Fractures: The decrease in bone density of vegans in this study was similar to that reported in the 2009 study I discussed above. However, rather than simply speculating about the clinical significance of this decrease in bone density, the authors of this study also measured the frequency of fractures in vegans, vegetarians, and omnivores. Here is what they found.

Vegans and vegetarians combined had a 32% higher risk of bone fractures than omnivores.

The effect of diet on risk of bone fractures was statistically significant for vegans (44% higher risk of bone fracture) but not for vegetarians (25% higher risk of bone fractures).

These data suggest the decreased bone density in vegans is clinically significant.

The authors concluded, “The findings of this study suggest that both vegetarian and vegan diets are associated with lower bone density compared with omnivorous diets. The effect of vegan diets on bone density is more pronounced than the effect of vegetarian diets, and vegans have a higher fracture risk than omnivores. Both vegetarian and vegan diets should be appropriate planned to avoid dietary deficiencies associated with bone health.”

The Secrets To A Healthy Vegan Diet

The answer to this question lies in the last statement in the author’s conclusion, “Both vegetarian and vegan diets should be appropriate planned to avoid dietary deficiencies associated with bone health.”

The problem also lies in the difference between what a nutrition expert considers a vegan diet and what the average consumer considers a vegan diet. To the average consumer a vegan diet is simply a diet without any animal foods. What could go wrong with that definition? Let me count the ways.

Sugar and white flour are vegan. A vegan expert thinks of a vegan diet as a whole food diet – primarily fruits, vegetables, whole grains, beans, nuts, and seeds. A vegan novice includes all their favorites – sodas, sweets, and highly processed foods. And that may not leave much room for healthier vegan foods.

2) Big Food, Inc is not your friend. Big Food tells you that you don’t need to give up the taste of animal foods just because you are going vegan. They will just combine sugar, white flour, and a witch’s brew of chemicals to give you foods that taste just like your favorite meats and dairy foods. The problem is these are all highly processed foods. They are not healthy. Some people call them “fake meats” or “fake cheeses”. I call them “fake vegan”.

If you are going vegan, embrace your new diet. Bean burgers may not taste like Big Macs, but they are delicious. If need other delicious vegan recipe ideas, I recommend the website https://forksoverknives.com.

3) A bone healthy vegan diet is possible, but it’s not easy. Let’s go back to the author’s phrase “…vegan diets should be appropriate planned to avoid dietary deficiencies associated with bone health.” A vegan expert will do the necessary planning. A vegan novice will assume all they need to do is give up animal foods.

As I said earlier, vegan diets tend to be low in calcium, vitamin D, zinc, vitamin B12, protein, and omega-3 fatty acids. Let’s look at how a vegan expert might plan their diet to get enough of those bone-healthy nutrients.

- Calcium. The top plant sources of calcium are leafy greens and soy foods at about 100-250 mg (10-25% of the DV) of calcium per serving. Some beans and seeds are moderately good sources of calcium. Soy foods are a particularly good choice because they are a good source of calcium and contain phytoestrogens that stimulate bone formation.

A vegan expert makes sure they get these foods every day and often adds a calcium supplement.

- Protein. Soy foods, beans, and some whole grains are the best plant sources of protein.

It drives me crazy when a vegan novice tells me they were told they can get all the protein they need from broccoli and leafy greens. That is incredibly bad advice.

A vegan expert makes sure they get soy foods, beans, and protein-rich grains every day and often adds a protein supplement.

- Zinc. There are several plant foods that supply around 20% the DV for zinc including lentils, oatmeal, wild rice, squash and pumpkin seeds, quinoa, and black beans.

A vegan expert makes sure they get these foods every day and often adds a multivitamin supplement containing zinc.

- Vitamin D and vitamin B12. These are very difficult to get from a vegan diet. Even vegan experts usually rely on supplements to get enough of these important nutrients.

4) Certain vegan foods can even be bad for your bones. I divide these into healthy vegan foods and unhealthy “vegan” foods.

- Healthy vegan foods that can be bad for your bones include.

- - Pinto beans, navy beans, and peas because they contain phytates.

- - Raw spinach & swiss chard because they contain oxalates.

- - Both phytates and oxalates bind calcium and interfere with its absorption.

- - These foods can be part of a healthy vegan diet, but a vegan expert consumes them in moderation.

- Unhealthy “vegan” foods that are bad for your bones include sodas, salt, sugar, and alcohol.

- - The mechanisms are complex, but these foods all tend to dissolve bone.

- - A vegan expert minimizes them in their diet.

5) You need more than diet for healthy bones. At the beginning of this article, I talked about the 3 essentials for bone formation – calcium, vitamin D, and exercise. You can have the healthiest vegan diet in the world, but if you aren’t getting enough weight bearing exercise, you will have low bone density. Let me close with 3 quick thoughts:

- None of the studies included in this meta-analysis measured how much exercise the study participants were getting.

- The individual studies were generally carried out in industrialized countries where many people get insufficient exercise.

- The DV for calcium in the United States is 1,000-1,200 mg/day for adults. In more agrarian societies dietary calcium intake is around 500 mg/day, and osteoporosis is almost nonexistent. What is the difference? These are people who are outside (vitamin D) doing heavy manual labor (exercise) in their farms and pastures every day.

In summary, a bone healthy vegan lifestyle isn’t easy, but it is possible if you work at it.

The Bottom Line

A recent meta-analysis asked two important questions about vegan diets.

Do vegans have lower bone density than omnivores?

2) Is the difference in bone density clinically significant? Are vegans more likely to suffer from bone fractures?

The study found that:

Vegans had 5.5%–7% lower bone density than omnivores depending on where the bone density was measured.

Vegans were 44% more likely to suffer from bone fractures than omnivores.

The authors of the study concluded, ““The findings of this study suggest that…vegan diets are associated with lower bone density compared with omnivorous diets, and vegans have a higher fracture risk than omnivores…Vegan diets should be appropriate planned to avoid dietary deficiencies associated with bone health.”

In evaluating the results of this study, I took a detailed look at the pros and cons of vegan diets and concluded, “A bone healthy vegan lifestyle isn’t easy, but it is possible if you work at it.”

Which Diets Are Best In 2021?

March 16, 2021 by Dr. Steve Chaney

Which Diet Should You Choose?

Many of you started 2021 with goals of losing weight and/or improving your health. In many cases, that involved choosing a new diet. That was only 2 months ago, but it probably feels like an eternity.

For many of you the “bloom” has gone off the new diet you started so enthusiastically in January.

Perhaps the diet isn’t working as well as advertised…

Perhaps the diet is too restrictive. You are finding it hard to stick with…

Perhaps you are always hungry or constantly fighting food cravings…

Perhaps you are starting to wonder whether there is a better diet than the one you chose in January…

Perhaps you are wondering whether the diet you chose is the wrong one for you…

If you are rethinking your diet, you might want to know which diets the experts recommend. Unfortunately, that’s not as easy as it sounds. The diet world has become just as divided as the political world.

Fortunately, you have an impartial resource. Each year US News & World Report invites a panel of experts with different points of view to evaluate popular diets. They then combine the input from all the experts into rankings of the diets in various categories.

If you are still searching for your ideal diet, I will summarize the US News & World Report’s “Best Diets In 2021”. For the full report, click on this link.

How Was This Report Created?

US News & World Report recruited panel of 25 nationally recognized experts in diet, nutrition, obesity, food psychology, diabetes, and heart disease to review the 39 most popular diets. They rated each diet in seven categories:

How easy it is to follow.

Its ability to produce short-term weight loss.

Its ability to produce long-term weight loss.

its nutritional completeness.

Its safety.

Its potential for preventing and managing diabetes.

Its potential for preventing and managing heart disease.

They converted the experts’ ratings to scores 5 (highest) to 1 (lowest). They then used these scores to construct nine sets of Best Diets rankings:

Best Diets Overall combines panelists’ ratings in all seven categories. However, all categories were not equally weighted. Short-term and long-term weight loss were combined, with long-term ratings getting twice the weight. Why? A diet’s true test is whether it can be sustained for years. And safety was double counted because no diet should be dangerous.

Best Commercial Diets uses the same approach to rank 15 structured diet programs that require a participation fee or promote the use of branded food or nutritional products.

Best Weight-Loss Diets was generated by combining short-term and long-term weight-loss ratings, weighting both equally. Some dieters want to drop pounds fast, while others, looking years ahead, are aiming for slow and steady. Equal weighting accepts both goals as worthy.

Best Diabetes Diets is based on averaged diabetes ratings.

Best Heart-Healthy Diets uses averaged heart-health ratings.

Best Diets for Healthy Eating combines nutritional completeness and safety ratings, giving twice the weight to safety. A healthy diet should provide sufficient calories and not fall seriously short on important nutrients or entire food groups.

Easiest Diets to Follow represents panelists’ averaged judgments about each diet’s taste appeal, ease of initial adjustment, ability to keep dieters from feeling hungry and imposition of special requirements.

Best Plant-Based Diets uses the same approach as Best Diets Overall to rank 12 plans that emphasize minimally processed foods from plants.

Best Fast Weight-Loss Diets is based on short-term weight-loss ratings.

The Top 5 (Excluding Commercial Diets):

#1: Atkins Diet

#2: Biggest Loser Diet

#3: Keto Diet

#4: Raw Food Diet

#5: Volumetrics Diet

Which Diets Are Best For Rapid Weight Loss?

Let me start with some general principles:

#1: If you are looking for rapid weight loss, any whole food restrictive diet will do.

The Atkins and keto diets are meat heavy, low carb diets. They restrict fruits, some vegetables, grains, and most legumes.

The Biggest Loser diet relies on restrictive meal plan and exercise programs.

The restrictions of the raw food diet are obvious.

The volumetrics diet restricts foods with high caloric density.

The vegan diet, which ranks #7 on this list, is a very low fat diet that eliminates meat, dairy, eggs, and animal fats.

I did not include commercial diets that rated high on this list, but they are all restrictive in one way or another.

#2: Restrictive diets ultimately fail.

The truth is 90-95% of people who lose weight quickly on a restrictive diet regain most of that weight in the next two years. The pounds come back and often bring their friends along as well. Many people regain more weight than they lost. This is the famous “Yo-Yo Effect”.

If dieters paid for one of the commercial diets, they may as well have burned their money.

When I talk with people about weight loss, many of them tell me the Atkins diet is the only one they can lose weight on. That would be impressive if they were at a healthy weight, but most are not. They are overweight. I am starting to see the same thing from overweight people who have used the keto diet to lose weight and have regained their weight.

#3: We should ask what happens when we get tired of restrictive diets and add back some of your favorite foods.

If you lose weight on a vegan diet and add back some of your favorite foods, you might end up with a semi-vegetarian diet. This is a healthy diet that can help you maintain your weight loss.

If you lose weight on the Atkins or keto diets and add back some of your favorite foods, you end up with the typical American diet – one that is high in both fat and carbs. This is not a recipe for long-term success.

Long term weight loss is possible if you transition to a healthy diet after you have lost the weight. In a recent article in “Health Tips From The Professor” I wrote about an organization called the National Weight Control Registry. These are people who have been successful at keeping the weight off. For purposes of this discussion, two points are important.

They lost weight on every possible diet.

They kept the weight off by following a healthy reduced calorie, low fat diet. (For what else they did, click here).

Which Diet Should You Choose?

With rapid weight loss out of the way, let’s get back to the question, “Which Diet Should You Choose?” My recommendations are:

Choose a diet that fits your needs. That is one of the things I like best about the US News & World Report ratings. The diets are categorized. If your main concern is diabetes, choose one of the top diets in that category. If your main concern is heart health… You get the point.

Choose diets that are healthy and associated with long term weight loss. If that is your goal, you will notice that primarily plant-based diets top these lists. Meat-based, low carb diets like Atkins and keto are near the bottom of the lists.

Choose diets that are easy to follow. The less-restrictive primarily plant-based diets top this list – diets like Mediterranean, DASH, MIND, and flexitarian.

Choose diets that fit your lifestyle and dietary preferences. For example, if you don’t like fish and olive oil, you will probably do much better with the DASH or flexitarian diet than with the Mediterranean diet.

Finally, focus on what you have to gain, rather than on foods you have to give up.

- On the minus side, none of the diets include sodas, junk foods, and highly processed foods. Teose foods should go on your “No-No” list. Sweets should be occasional treats and only as part of a healthy meal. Meat, especially red meat, should become a garnish rather than a main course.

- On the plus side, primarily plant-based diets offer a cornucopia of delicious plant foods you probably didn’t even know existed. Plus, for any of the top-rated plant-based diets, there are websites and books full of mouth-watering recipes. Be adventurous.

The Bottom Line

For many of you the “bloom” has gone off the new diet you started so enthusiastically in January. If you are rethinking your diet, you might want to know which diets the experts recommend. Unfortunately, that’s not as easy as it sounds. The diet world has become just as divided as the political world.

There are probably two questions at the top of your list.

#1: Which diets are best for rapid weight loss? Here are some general principles:

If you are looking for rapid weight loss, any whole food restrictive diet will do.

Restrictive diets ultimately fail.

We should ask what happens when we get tired of restrictive diets and add back some of our favorite foods.

Long term weight loss is possible if you transition to a healthy diet after you have lost the weight.

#2: Which diet should you choose? Here the principles are:

Choose a diet that fits your needs.

Preventing And Reversing Osteoporosis

A Bone Health Lifestyle

Fall is glorious in my book. I was up in New York a few weeks ago, and the trees were just changing – I was about a week too early for the best colors, but it was still beautiful. Then I flew out to Lake Tahoe, and it was really beautiful there. The air was crisp and clean, and I loved all the fall decorations.

In Florida we are entering our most wonderful time of year. It’s starting to get cooler, the humidity is going down, and hurricane season is over. Hooray! It’s great to be outdoors again!

Please remember all the people who are still going through very difficult times in the Bahamas. Many people have lost their homes, their workplaces and the income that supports them, and some have lost loved ones. A devastating loss.

We here in the USA were blessed that Dorian didn’t come any further west and do the same thing to Florida, Georgia, and the Carolinas. I wanted to share what I have with the people who now have nothing. That made me search for places I trust that will send all the money I donate. In case you want to help, and you don’t have a favorite charity, I want to share those places with you:

Preventing And Reversing Osteoporosis

Weight-bearing exercise builds strong bones. That statement is so common that just about everyone knows they need to exercise for strong muscles and bones, and for all the good it does for just about every system in the body. And, we are what we eat, so nutrition is vital.

Do you like to exercise? Some people are almost addicted to exercise, but I’m not one of them. I go to the gym and I have a fitness trainer to help me stay on track, but it fits right in with my eagerness of going to the dentist. I must say, I’d like that to change, and maybe if I can find a workout partner, it will.

Meanwhile I need to do something because I’ve been told I have osteoporosis. Yikes! One thing for sure, I’m not taking any type of medication. I truly believe there is another solution.

While I’m not an exercise nut, I do love nutrition and I know that the body is so adaptable that if it’s given the proper nutrition, it can do miracles. I believe nutrition and exercise can reverse this osteoporosis diagnosis.

A Bone Healthy Lifestyle

The first thing I did was contact my friend, Steve Chaney, PhD, author of the weekly blog “Health Tips From The Professor. He pointed me to an article he had written on a “Bone Healthy Lifestyle”. Here is a brief summary:

Exercise, calcium, and vitamin D are all essential for bone formation. If any of them are missing, you can’t form healthy bone. The reason so many clinical studies on calcium supplementation and bone density have come up empty is that exercise, or vitamin D, or both were not included in the study.

Get plenty of weight bearing exercise. This is an essential part of a bone healthy lifestyle. Your local Y can probably give you guidance if you can’t afford a personal trainer. Of course, if you have physical limitations or have a disease, you should consult with your health professional before beginning any exercise program.

Get your blood 25-hydroxy vitamin D level tested. If it is low, take enough supplemental vitamin D to get your 25-hydroxy vitamin D level into the adequate range – optimal is even better. Adequate blood levels of 25-hydroxy vitamin D are also essential for you to be able to utilize calcium efficiently.
Consume a “bone healthy” diet that emphasizes fresh fruits and vegetables, minimizes meats, and eliminates sodas and other acidic beverages. For more details on whether your favorite foods are acid-forming or alkaline-forming, you can find plenty of charts on the internet.
Minimize the use of medications that adversely affect bone density. You’ll need to work with your doctor on this one.
Consider a calcium supplement. Even when you are doing everything else correctly, you still need adequate calcium in your diet to form strong bones. Dr. Chaney wasn’t advocating a “one-size fits all” 1,000 to 1,200 mg/day for everyone. Supplementation is always most effective when you actually need it. For example:

o If you are not including dairy products in your diet (either because they are acid-forming or for other health reasons), it will be difficult for you to get adequate amounts of calcium in your diet. You can get calcium from other food sources such as green leafy vegetables. However, unless you plan your diet very carefully you will probably not get enough.

o If you are taking medications that decrease bone density, that may increase your need for supplemental calcium. Ask your pharmacist about the effect of any medications you are taking on your calcium requirements.

If you do use a calcium supplement, make sure it is complete. Don’t just settle for calcium and vitamin D. At the very least you will want your supplement to contain magnesium and vitamin K. Dr. Chaney recommends that it also contain zinc, copper, and manganese.

Between increasing my exercise and ramping up all the nutrients that build bone, I just know that by this time next year I’m going to be surprising the doctor with my great health
