Nutrition for Bone Health

Calcium
When you think bone health, what is the first nutrient you think of? I’m going to go out on a limb and guess that you said Calcium! Yep, calcium is crucial for bone health. It is the key component of hydroxyapatite, which makes of the mineral matrix that keeps you teeth and bones sturdy and strong. Our bones are also constantly breaking down and building up – and in order to properly build, they need adequate amounts of calcium. This “adequate amount” ranges from 1,000mg- 1,300mg per day depending on age and gender and mainly comes from dairy products, almonds, leafy greens, tofu, beans, lentils, and some fish fish.

Vitamin D
Now, while calcium is the key component in bone, it pretty much is no good without its partner in crime, vitamin D. Vitamin D is needed for calcium absorption, so no matter how much calcium you eat (or drink), your body isn’t absorbing much of it if you lack vitamin D. Vitamin also helps in that bone remodeling (breakdown and building) process I mentioned.

Vitamin D has become a pretty hot nutrition topic recently. In fact, vitamin D deficiency is on the verge of becoming a global public health issue. Why? Well, if you are reading this post right now, you are likely sitting inside staring at a computer or phone screen as opposed to soaking up the sun’s UV rays. Our primary source of vitamin D comes from the sun so the decreased time spend outdoors and the increased use of sunscreen that have been seen around the globe are causing vitamin D deficiency rates shoot through the roof!

There are a few food sources of vitamin D, including fortified dairy products, some fatty fish, and mushrooms, but these can’t really provide enough to meet our need of 600-800 IU per day (and most people need up to 2,000 IU per day if they are deficient).

Exercise
The final key player in bone health isn’t a nutrient; it is exercise!- specifically weight-baring exercise. Simply carrying the weight of your skeleton in activities like walking, running, jumping, and stair climbing all help in that formation of strong bones. Not to mention, exercise improves strength and balance, which can help decrease risk of falls and broken bones.

Other Nutrients
In addition to these top three, researches have also found that low vitamin C and vitamin K levels also put people at risk of poor bone mineralization. On the other hand, people who had diets high in fruits and vegetables were found to have stronger bones… just one of the millions of reasons to eat more fruits and veggies!

Controversy
A few studies have found that high calcium intake, greater than the recommended daily intake doesn’t provide any additional benefit when it comes to bone mineral density. There have also been associations between high calcium intake (especially from supplements) and heart disease risk. Moral of the story- more calcium isn’t always better.

Artificial Sweeteners: Not so sweet after all

The next time you are about to tear open that yellow, blue, or pink packet or reach for a diet beverage, you may want to think twice. Throughout the 1900’s, artificial sweeteners seemed to be the miracle food – all the delicious sweetness people enjoy, without any of the sugar or calories. But now this “miracle food” might not be such a miracle after all. Recent research has been showing that these artificial sweeteners may be doing more harm than good!

One study of over 400,000 people found that, even though artificial sweeteners don’t have any calories, they did not help people lose weight. In fact, they found consuming more artificial sweeteners lead to weight gain and obesity, diabetes, and heart disease.

How could this be possible? Less calories should mean more weight loss, right? Well, just because the sweeteners aren’t providing any calories, doesn’t mean we aren’t getting more calories elsewhere. One Harvard doctor explained that artificial sweetener consumption could cause overstimulation and desensitization of our sugar receptors, which causes people to crave sweeter and sweeter foods. It can also end up making un-sweet foods (such as vegetables) unpalatable. These sugar cravings and vegetable aversions lead to people eating more sugary and high calorie foods, which cancel out any reduction in calories from using artificial sweeteners.

Also, remember the gut microbiome I talked about in my post about Probiotics? Well, researchers found artificial sweeteners can change your gut bacteria…and not in a good way! The sweeteners increase the number of Bacteroides, an “energy hoarding” bacteria species that make it nearly impossible to lose weight. Other changes in the microbiome, caused by artificial sweeteners, make it more difficult for your body to breakdown sugar – leading glucose intolerance and diabetes.

If you are looking for any bright sides, using artificial sweeteners in place of sugar can decrease likelihood of cavities and tooth decay, and while there is a lot of hoopla around artificial sweeteners causing cancer, there haven’t been any concrete studies to prove this. But! We only have short-term studies…we don’t really know what the effects of long-term use are.

In the end, regardless of weight gain, cravings, and diabetes, artificial sweeteners are, well, artificial. I don’t know about you but I would rather avoid putting artificial chemicals in my body and stick with the real stuff (in moderation, of course) if I had the choice.

Turmeric & Golden Milk

If you don’t have a trail of this yellow/orange powder around your kitchen, you might be missing out. Turmeric is a hot topic right now and for good reason – it has tons of health benefits.

Historically, turmeric was used in Ayurvedic, eastern medicine for pain and fatigue. Turns out they were on to something… Recent research has found that curcumin, the active compound in turmeric, has some serious anti-inflammatory effects.

Why is “anti-inflammatory” a good thing?

In a few cases, inflammation is a good thing – like healing cuts or wounds and fighting foreign pathogens in the body. However, when there is a chronic, low level of inflammation in the body it can increase risk for heart disease, cancer, metabolic syndrome, and Alzheimer’s, among many others. Stress, environmental toxins, and chemicals and preservatives in our food can all cause some of this chronic inflammation, which turmeric can help counteract.

Does turmeric sound appealing now?

If adding turmeric into your diet sounds more appealing now, here are a few things to consider:

  1. Whether you’re adding turmeric to your stir fry, eggs, golden milk (see my favorite recipe below!), salads, or soups, make sure you add some black pepper – this boosts absorption of the curcumin in turmeric up to 2000%
  2. While it is more of a pain to cook with, raw turmeric root more potent than the powdered spice form of turmeric

Remember…

Just like any other food or supplement, turmeric is not a magic pill. In order to get the real anti-inflammatory benefits of turmeric, it is also important to be eating a diet rich in whole, real foods (not the processed stuff), fruits and vegetables, and fiber.

Probiotics

Last Wednesday the nutrition department at school had their annual symposium. This year’s topic: the gut microbiome. The microbiome is a pretty hot topic right now. There is so much interesting research on how it affects our health so there is no way I could share everything with you in one post (or even a few!). If you aren’t familiar with the microbiome, it is the collection of the billions of different bacteria (both good and bad) that live inside our guts, and the composition (both the type and number) these bacteria play a role in our health. They can influence whether or not we get certain diseases, how efficiently our metabolism runs, our hormone levels, our immune system, and much, much more. And guess what? Diet is the #1 factor that determines which bacteria live in our gut!

So how do you make sure your microbiome is in tip-top shape? Well, there are many different things to think about, but I am going to just focus on 1 here today — probiotics.

Most of us have probably heard of probiotics in a few contexts – supplements and yogurt. Probiotics are actually live, good bacteria that help create a good balance of the different bacteria in your gut. In other words, they help improve your microbiome, which is good news for your health and digestion.

How much do you need? Taking 1 probiotic supplement every day or consuming 2-4 tablespoons of fermented foods every day is optimal.

If you are going to take a supplement, you want to pay attention to the strains and the CFUs.

  • Strains are the number of different types of bacteria in the supplements. Try to find a supplement with at least 5 different strains to get the most benefit (the more the better).
  • CFUs are the colony forming units or the actual number of live bacteria in the supplement. Aim for a supplement with 25-30 billion CFUs. Some people can benefit from up to 900 billion CFU’s, including those with IBD and celiac, but 25-30 billion is typically enough for healthy individuals.

Sound too science-y and confusing? Eating 2-4 tablespoons of probiotic containing foods is just as good! Probiotics are found in fermented foods like unpasteurized sauerkraut (the stuff you find in the fridge), kefir, yogurt, kimchi, apple cider vinegar, and tempeh. Getting probiotics from just one of these foods is great, but mixing up your sources of probiotics is extra helpful.

My Experience on Whole30

Don’t mind me just sitting over here indulging in a big bowl of ice cream.

The cycle of restricting foods (and dieting) and then binging on “unhealthy” or “forbidden” foods has never been as clear to me as it is right now. That’s because I just completed day 30 (the last day) of the Whole30 diet.

After my experiment as a vegetarian for a month, I thought I would try out another diet. The lucky winner- Whole30. Whole30 is a diet designed to “end unhealthy cravings and habits, restore a healthy metabolism, heal your digestive tract, and balance your immune system”. Sounds great until you hear what is involved. On Whole30 you aren’t allowed ANY grains, legumes, sugar, sweetener (including things like honey), dairy, soy, or alcohol. What does that leave you ask? I have pretty much spent the last month eating only meat, fish, eggs, fruits, and vegetables. It got real boring, real fast to say the least.

If you catch my drift, it was not an enjoyable experience. If you have read many of my previous posts or know me well, you know that I am not one to cut any foods out of my diet – you name it, I’ll probably eat it (yes, even as a nutrition student and future dietitian I eat (and love) chocolate, ice cream, buttered popcorn, and even a loose with chili cheese fries from Detroit’s Lafayette Coney Island), so having to cut so many things out of my diet was a challenge.

In theory, sticking to a diet made up of whole foods is great, but not allowing any wiggle room leads to overeating all of the “forbidden foods” later on (aka the big bowl of ice cream I am having). Cutting out foods can create an unhealthy relationship with food, it is restrictive, not sustainable, and most of all, it isn’t fun.

So, how was Whole30?

Like I said before, it is really boring because there wasn’t a lot of variety. It was also very difficult to go to restaurants or gatherings with food since there were so many things that were off limits.

Do I feel better?

Honestly, I don’t feel any different – aside from the fact that all I want to do is eat dessert, bread, and a big chipotle burrito bowl. But also remember, my diet was pretty rich in fruits, vegetables, and lean proteins before. It wasn’t like I was starting out eating McDonald’s on the daily.

Would I recommend Whole30?

That would be a big fat NO! I see no reason why you have to cut out things like whole grain bread that is packed with fiber, beans that are a good source of plant based protein, and dairy products that are full of calcium and protein. I actually think you end up in an even worse situation after Whole30. Think about the restricting and binging cycle I mentioned — after 30 days of restricting, all you want to do is overeat/binge on the foods you avoided for a month. (It has even been difficult for me, someone who is very aware of these restrict and binge patterns, to resist eating an entire pint of ice cream and a loaf of bread right now.)

On the other hand, I do think the emphasis of fruits, vegetables, and lean protein is great! Everyone could benefit from eating a few more of these and a few less sugary and starchy foods (since they make up the majority of a standard American diet). Note that I said “a few less”, not “eliminate” the sugary and starchy foods. There is no reason why pizza and chocolate can’t make there way into a healthy, balanced diet.

I think this pretty much sums up my thoughts on Whole30. Have you done Whole30? If so, what are your thoughts?

Coconut Oil

This week’s topic brought to you from the family dinner table last weekend.

It seems like coconut oil is everyone’s favorite oil right now. It is encouraged by the recently popular clean eating, paleo, and ketogenic diets. Why is it so popular? There may be some great health benefits of coconut oil, but there are still some fuzzy areas that need more research. When asked, most coconut oil users can’t tell you why they use it or why they think it is healthy, so I thought I would share some insight.

Cholesterol

There are two main types of fat: saturated and unsaturated. Saturated fat is considered the bad kind of fat which increases our LDL (bad) cholesterol. Unsaturated fat is known as the good or healthy kind of fat, which can decrease LDL cholesterol. Both saturated and unsaturated fats can boost your HDL (good) cholesterol a tiny bit, too.

Coconut oil is 90% saturated fat (which is more than the 65% saturated fat in butter!). Therefore, coconut oil, just like other saturated fats, increase that bad LDL cholesterol (not good!). However, coconut oil is unique in that it seems to give your HDL a little extra boost compared to all other fats.

This is where it gets confusing. Right now, when you go to the doctor, they test your blood for the amount of LDL particles and the amount of HDL particles in your blood, but they don’t look at the size of those particles. There has been some new research showing that the size of these cholesterol particles might be a more accurate measure of heart disease risk rather than the number of particles.

Here is where coconut oil comes in…while coconut oil increases the number of LDL particles (just like other saturated fats), it might increase the size of these particles, which could mean good news for your heart disease risk (the bigger the better!). But remember, this is still new research and we don’t consider this 100% fact yet.

MCTs

Then there are the infamous MCTs (medium chain triglycerides) that coconut oil is known for. MCTs don’t need to be digested the same way as other fats and are a readily available energy source for your cells. For this reason, they have historically been used as a therapeutic agent in people with fat malabsorption, cystic fibrosis, and epilepsy.

Most fat digestion requires the fats you eat to be transported to the liver via triglycerides in order to be used, but because MCTs don’t go through the normal digestion process, there are some studies showing they can decrease triglycerides and aid in weight loss. MCTs also have some anti-inflammatory properties, which is also good news from a health perspective.

Conclusions

While all of this sound great, I would still be a little skeptical. Much of this is just preliminary research, there are few research studies, and the results are inconclusive. So while coconut oil is fine every now and again, choosing oils high in unsaturated fats, like olive, sunflower, and avocado oils, are definitely the best choice as far as we know.

Being Vegetarian

Exactly four weeks ago I decided to become a vegetarian…temporarily. Yep, I have officially been a vegetarian for one full month. I had been pondering the idea for a while and I had finally used up all the chicken and turkey in my freezer, so I thought it would be a good time to start. (Oh, and I guess I should include that I just cut out all meat and fish. I still ate eggs and dairy.)

By no means did I plan on being a vegetarian forever, but as a future dietitian I thought it would be a good experience to walk in the shoes of vegetarian patients and clients that I will work with.

Anyways, I thought I would share some things I have learned from my experience with you this week.

The good, the bad, and the indifferent

The first question I have gotten from all my friends and family is, “how do you feel”, and honestly, I can’t say that I feel much different. Prior to my vegetarian experiment, I didn’t each much red meat at all; I mostly stuck to chicken, turkey, tuna, and salmon. Research has shown that there are a lot more benefits to cutting out red meat compared to other lean meats, so I don’t know if that has anything to do with the lack of change I have felt.

People are also very concerned about protein, so I’ll also mention that I was keeping track of my food intake using MyFitnessPal at the beginning to make sure I was getting enough protein. While I could easily meet my protein needs for the day, I had to be a lot more conscious of including it at every meal and snack than I was before.

With that being said, eating out was a struggle– not because there aren’t any vegetarian option (you can get pasta and potatoes pretty much anywhere), but because restaurant menus lack vegetarian protein sources. I especially had a hard time in the cafeteria at the hospital. After the first week I started bringing a container of tofu and beans to add to salads and soups to make sure I got my protein in.

So while it may have been a little difficult at times, I actually am really happy that I gave vegetarianism a shot. I had to get super creative in the kitchen, and find new ways to incorporate tofu, tempeh, beans, and eggs into my meals to make sure I got enough protein in for the day (which means lots of new vegetarian recipes and food combination to share in the coming weeks!). I also now have a good basis of vegetarian recommendations for any patients or clients who come to me with questions.

And finally (skip this section if you don’t want to hear about flatulence and bowel movements), vegetarianism has made me very regular. Vegetarian diets tend to be a lot higher in fiber which kept everything moving smoothly. The first week I was a little gassy (probably due to all the beans I was eating), but my body got use to it and I have been fine ever since.

Overall thoughts

I think a lot more good came out of this experiment than bad. I have cooked up some new things in the kitchen and have had experiences that will help me be a better dietitian. Meeting protein needs can be tough but definitely manageable if you plan ahead.

While I think going completely vegetarian isn’t really necessary (unless you would like to, of course), there are lots of benefits to being a vegetarian. Plant-based diets usually have a lot more fiber, vitamins, and minerals. There is also lots of research showing that decreasing meat intake can help prevent chronic diseases, aid in weight loss, and save the environment.

If I were to give any recommendations, I would say that it is always beneficial to cut back on red meat intake (Eat it no more than 1x per week) and increase you fruit and veggie intake. You can also try Meatless Mondays or another modified version of being a vegetarian to get some of the benefits (such as meatless lunches during the week).

Looking forward

This week I am planning on including a lot of fish and meat to see if I feel any different (I give you any updates in next weeks post). After that, I’ll definitely be adding fish and meat back into my diet but probably not in the same quantities as before. I am going to continue to include vegetarian meals on a regular basis because they both healthy and – more importantly – they taste good!

Considerations

If you are or decide to become a vegetarian or vegan long-term (longer than 1-2 months), I suggest seeing a dietitian (or sending me an email, I’m happy to help!) since there are some vitamin and mineral deficiencies that can occur if you aren’t taking supplements.
