Is Japanese food Healthy?

I can’t believe today is the last first day of school I will ever have (at least in the near future). There are only the 15 weeks (one semester) standing between me and a master’s degree! With my last “official” summer as a student behind me, I can’t go without talking about my summer adventure to Japan.

I just got home from the steaming hot country last week and had an incredible time! We did lots of walking (definitely hit my 10,000 steps every day), lots of sightseeing, and of course, lots of eating. I checked out tons of local grocery stores and had to try almost every street food we passed.

All of the sushi, ramen, rice, fish, and Japanese omelets were so delicious — I could hardly get enough! However, by the last few days of our two-week trip I was definitely craving some vegetables (that weren’t fried into tempura!). My body wasn’t use to all the starchy rice and ramen noodles. I felt like most of the food I was eating was heavy and “unhealthy”.

I put unhealthy in quotations because there is not one definition of healthy. We, in the United States, are conditioned to believe that noodles and rice (among all other starchy, high-carb foods) are “unhealthy” and cause weight gain. With that messaging, you would think that everyone in Japan would be obese, but guess what?…I didn’t notice a single Japanese person that was severely overweight.

The obesity rate in Japan is a mere 3.5% compared to over 35% in the United States! How could it be possible that Japanese people constantly eat “unhealthy” food for several meals a day but aren’t overweight?

Quite timely as I returned from my trip, I received an email with an article from SELF Magazine entitled “Our Idea of Healthy Eating Excludes Other Cultures, and That’s a Problem”. A Registered Dietitian whose family was from Trinidad wrote the article, and she discussed how our portrayal of “healthy” food is very Eurocentric and makes people think that foods from other cultures are “unhealthy”.

Think about it, most people say their night out at a Mexican restaurant was “unhealthy” – and while maybe there were a few too many chips and margaritas, this Americanized version of a Mexican meal makes us (and potentially Mexican Americans) label Mexican food as “bad”. This same notion goes for Japanese food. Obviously the Japanese are doing something right if their obesity rate is just a fraction of ours.

All of this made me realize that, as a Dietitian and health professional, I need to be more aware of different cultures and their dietary habits, and as an American society, we can’t label peoples’ cultural foods as “good” and “bad”. We also can’t expect people to give up their culture, heritage, and ancestry to eat what the stereotypical Eurocentric “healthy diet”.

Just some food for thought 🙂

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.

Eggs: What do all the label claims mean?

$1 for 18 or $6 for a dozen? Standing in front of dozens of eggs (no pun intended) on the self at the grocery store makes for a very confusion decision. Free range or pasture raised? Cage free or Organic? – don’t worry, it confuses me too so I thought I would break down just a few of the many claims on egg packages to help you make a more educated decision the next time you pick up a carton.

• Cage free means that the animals don’t live in cages

You are all probably thinking..”duh”. But just because the animals aren’t in cages doesn’t mean they aren’t packed in a barn, and most of the time they never step foot outside.

• Free range means that animals have “access to the outdoors”.

While this “access to the outdoors” has to be government certified, there really aren’t any guidelines, criteria, or qualifications on the quality or size of the outdoor space. That means the area could be anything from a small cement square to a grassy field.

• Pasture Raised usually means that animals spent the majority of their time in a large open grass field – think the classic image of chickens in a field.

While pasture raised sounds the best, it isn’t regulated by the government so technically some unethical farmer could slap “pasture raised” on their conventional eggs and wouldn’t get in trouble for it.

• Organic requires that the chickens be raised in conditions that accommodate their natural behaviors.

This includes area to roam outdoors in fields, but the key word is “accommodate”. Yes, they may accommodate for natural habits, but that doesn’t always mean they actually have the ability to live naturally 24/7. On another note, “organic” eggs also come from chickens that are not treated with any antibiotics and they are fed all organic feed – all of which are tightly regulated by USDA.

This chart is a pretty good summary of all the different egg labels- but remember, while it shows that pasture raised is the best, that term isn’t regulated so anyone can use it willy-nilly. Do some research into the brands of eggs at the store to see how they actually treat their chickens.

So you choose…what kind of eggs do you buy?

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 4^th 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 4^th 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) 4^th!

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

Back to the Beverage Basics

This week, I am going back to some basics. While I love writing about all the cool, new nutrition research I learn at work and at school, I sometimes forget that many people have a tough time making basic healthy choices – especially when it comes to what they are drinking.

In many of my rotations at the hospital, people overlook drinks as a source of nutrition. I have seen overweight patients who just can’t figure out why they aren’t losing weight while eating eggs for breakfast, a salad, for lunch, and grilled chicken for dinner. Guess what? These people also drink crazy chocolate-y, sugary Starbucks drinks, several glasses of orange juice per day, and bottle on bottles of pop/soda. I even had one patient who admitted to drinking over 2 liters of orange juice every day – that’s about 946 calories and 176 grams of sugar!! I know this is an extreme scenario, but it is so easy to lose sight of how easily those fluid calories can add up.

When I am working with patients who want to lose weight, my number one piece of advice is to switch to zero calorie beverages with no artificial sweeteners. Yes, diet coke is zero calories, but all the artificial sweeteners wreak havoc on your digestion and bacteria in your gut (more on this in a future post, but for now, avoid all artificial sweeteners).

So what type of beverages do I recommend?

Number 1 is always water! Hot, cold, with lemon, berries, or cucumbers…water is always the best option. I love mine ice cold with a wedge of lemon, of course!

If you aren’t a fan of water, try the unsweetened, flavored, sparking waters that are all over Instagram and Facebook, like LaCroix or Bubly. While these are all better options than pop or sugary drinks, I still encourage people to stick with fluids that aren’t sparkling. There is some newer research showing that all the carbonation can acid reflux and increase ghrelin levels (the hormone that makes you feel hungry).

You can also pick up a cup of coffee. No, not a double chocolate Frappuccino with umpteen pumps of flavor or even a cup with some Splenda…just a plain old cup of black coffee (maybe with a splash of milk). Two to three, 8 ounce cups of coffee per day has been found to decrease risk of many diseases and help you live longer. Unsweetened tea, hot or cold, is also a good option.

Ultimately, my top beverage recommendations are:
1. Water
2. Unsweetened tea
3. Black coffee
4. Zero-calorie flavored water
*1-2 glasses of milk each day (any variety) is also okay. There is lots of new and controversial research about milk, but I’ll save that topic for another day.

Stay away from:
1. Pop/Soda (diet and regular)
2. Juice (even the 100% natural kind)
3. Fancy, sugary coffee drink
4. Gatorade and other sports drinks (unless you are a competitive athlete)

I challenge you to cut out all fluid calories – that could add up to a few hundred calories per day or ½ pound per week!

 

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.

My favorite turmeric recipe – Golden Milk

 

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.

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.
