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.

5 Tips for a Healthy Summer BBQ

Can you believe it is almost July?!? I sure can’t.

I hope your grill is hot and your tummy is grumbling for some barbecue because the 4th of July is right around the corner.

In lieu of this festive holiday typically filled with hotdogs and s’mores, I thought I would share some of my favorite tips and tricks for a healthy 4th of July (or any summer night) BBQ.

  1. Load up on veggies – If your cooking, grill a bunch of kebabs full colorful peppers, tomatoes, and broccoli. If you aren’t the one cooking, bring a big veggie tray with hummus or guac and fill your plate! Vegetables provide so many vital vitamins and minerals, plus they help fill you up without breaking the calorie bank.
  2. Cut the carbs in half – Yep, I’m talking about the (whole grain!) bun. This one is tricky if you are having a hot dog, but if you go for a hamburger, go open face so you only get half the bun’s carbs and calories. Or, if you are feeling super healthy, try two big pieces of lettuce for your bun.
  3. Water, water, water! – I know pop, lemonade, and iced tea are BBQ classics, but you can easily save 200+ calories by only drinking water. And an extra bonus – water will help keep you hydrated with all the extra salt you might be getting from that hot dog and side of potato chips.
  4. Choose fruit for dessert – ‘Tis the season of nice, juicy watermelons and delicious fruit salads. Take advantage of natures candy and munch on some nutrient filled grapes and berries instead of reaching for the bag of marshmallows.
  5. Get moving – Go for a walk and enjoy the weather after dinner, or play with the kids in the back yard. Planning an activity for after the meal can help prevent overeating (since nobody wants to run around on an overly full stomach). Exercise also helps your food digest better – not to mention you burn a few extra calories in the process.

Happy Grilling, Happy Summer, and Happy (early) 4th!

The Official Trans Fat Ban!

Food/Health History Update:

Mark your calendars everyone because tomorrow is a very important day in United States nutrition history… Partially hydrogenated oils (also known as trans fats) will officially be illegal and will no longer be found in any food products sold in the United States.

Reminder- trans fats are a type of fat found in chemically produced partially hydrogenated oils, that, even in very small amounts, are responsible for raising cholesterol levels through the roof and increasing risk for heart attack, stroke, and diabetes. Frozen pizzas, solid margarines, frosting, packaged cookies and crackers, and fried foods like onion rings and fries are just some of the common foods where trans fats can be found.

Back in 2015, the FDA finally realized that trans fats were no longer safe for people to eat and removed them from the GRAS (“Generally Recognized as Safe”) list of ingredients. The FDA gave companies until June 18, 2018 (tomorrow!) to have them eliminated from all products. (See my post back in 2016 all about the ban.)

Now, the world is following suit (hopefully!). On May 14, 2018, the World Health Organization (WHO) launched an initiative to eliminate trans fats globally. While many westernized countries have already eliminated trans fats or are in the process of doing so, countries in southern Asia, Oceana, and Central/South America are still consuming dangerously high amounts of these processed fats. WHO can’t actually create any worldwide law or ban, but it will be part of their strategic plan to help countries around the world achieve a trans fat-free food supply. And guess what (this blew my mind)…WHO has never called to completely eliminate anything other than a specific disease! – Shows you just how bad trans fats are!

Happy Father’s Day!

 

*Note- unfortunately the FDA has extended the June 18, 2018 deadline for trans fat removal under some conditions, but for the most part, they will all be eliminated. Read more here: https://www.fda.gov/Food/IngredientsPackagingLabeling/FoodAdditivesIngredients/ucm449162.htm

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.

Are egg yolks bad for you?

It is no secret that egg yolks are packed full of cholesterol (I think they win the gold medal for cholesterol content and are typically the number one source of cholesterol in our diets). People commonly opt for egg white omelets or low cholesterol egg substitutes to cut back on their cholesterol intake.

What is cholesterol?
Cholesterol is a waxy substance both in food (like egg yolks) and made by your liver, which is needed by all of your body’s cells in order to function. In other words, without cholesterol, we wouldn’t be able to survive.

Cholesterol Recommendations
In the 1960’s, American Heart Association, along with many other health organizations, recommended limiting cholesterol intake after researchers found high blood cholesterol levels were linked to heart disease. The typical recommendation was no more than 3 egg yolks per week.

But wait! Researchers are rethinking their “low cholesterol” recommendations. High blood cholesterol levels are still liked to heart disease, but we aren’t so sure that eating cholesterol really increases cholesterol levels in the blood. I know that seems illogical, but our liver actually produces way more cholesterol than we eat, so cutting back on your egg intake won’t really affect your cholesterol levels.

Don’t worry, I’m not just spewing science here… the U.S. government agrees and the Dietary Guidelines for Americans (published every 5 years by the USDA) eliminated the recommendation of limiting cholesterol in 2015.

Dietary Fat
While monitoring your cholesterol intake can be a thing of the past, you should keep saturated and trans fat on your radar. Newer research is showing that these two types of fat play a much more significant role in increasing blood cholesterol levels and heart disease risk compared to dietary cholesterol.

So when it comes to eggs, there is no need to trash the yolk. The yolk won’t increase your cholesterol levels, and it is full of healthy vitamins and minerals! Plus, eating whole eggs has been found to keep you more full, promote weight loss, protect brain health, and decrease inflammation.

Don’t Forget…
Diet isn’t the only thing that affects heart disease risk. High levels of inflammation, stress oxidative damage, along with high blood pressure, smoking, and low physical activity levels can all increase your risk, too.

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.
