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.

Top 5 Healthy Springtime Tips

Even though spring has barely sprung outside, the spring semester is coming to an end. Tomorrow is my last day of class for the semester! Thankfully I don’t have any final exams, just one presentation on Wednesday and then I will no longer say that I am in school and working at the hospital at the same time. Now I’m taking a week of rest and relaxation until I hit the books again to start studying for my RD board exams (it makes me nervous just thinking about it!).

Since we are well into spring, I thought I would just share some of my 5 favorite things to do in the spring to stay healthy and happy!

1. Go outside! I know the cold weather is still lingering (especially up here in Cleveland), but getting fresh air and sunlight has been found to increase energy, decrease stress, improve digestion, and give your immune system a boost. Going for a walk is a great way to try to hit your 10,000 steps for the day and soak up some vitamin D.
2. Clean! Throwing out all the unnecessary stuff in your house/apartment/room has some surprising benefits. Living in a clean and uncluttered space decreases stress levels and makes you more productive. Not to mention, people who live in clean spaces are more likely to eat healthy, and cleaning can be a bit of a workout 😉
3. Check out a farmers market! The growing season is in full swing and farmers markets are the perfect for stocking up on produce. They are a great way to try out a new fruit or vegetable, see what is in season, and support local farmers. Plus you get the great to know exactly where your food came from and how it was grown.
4. Socialize! The longer days and rooftop restaurants & bars are the perfect excuse to spend time with friends and family. Spending time talking with other people can boost mental health and reduce your risk for dementia.
5. This is a big one…get ready…Put your phone down! It is so easy to get caught up in the virtual world of work and social media that it can be hard to disconnect (I’m guilty of it too), but try to unplug for at least an hour every day. Maybe put your phone in airplane mode an hour before bed, don’t check email or social media for at least an hour after you wake up, or leave your phone at home while you do my first four tips. It will help you be less distracted, more productive, more present, and you might even talk to someone and make a new friend.

Happy spring!

It Isn’t Only About Calories

What is the first thing you think about when it comes to health or weight loss? I am pretty sure I can guess that it is either diet or exercise. Did I guess correctly?

While diet and exercise both play very critical roles in health and body weight, there are many other things that people tend to forget about. Yep, it more than just calories in versus calories out than can impact how you feel or how much you weigh.

Here are some things to think about:

  1. Sleep –Not only can lack of sleep leave you with brain fog and feeling tired, it can also make it difficult to lose weight. Here’s why: lack of sleep increases a hormone in your body called ghrelin- your hunger hormones that tells your brain it is time to eat. Therefore, lack of sleep can cause you to eat more calories and have more cravings. Also, just like a lack of sleep makes your brain feel tired, it makes your metabolism feel tired too. That means your body doesn’t function as efficiently and you aren’t burning calories the same way as you would if you were well rested. Not to mention, it is difficult to get in a good workout in when you’re tired.
  2. Stress – When you are stressed, your body goes into the “fight or flight” response (also called “survival mode”). Just like the name, your body is doing everything it can to survive; your cortisol (stress hormone) levels increase and your body stops using your fat stores for energy. Why? Because your body thinks it needs to hold on to and use all of its energy to deal with the stress. Think about it…in evolutionary history, stress use to mean running from a dangerous situation, which does in fact require lots of energy, but now our stressors (like work and school) don’t require the same amount of energy as running from animals does. High stress and cortisol levels also cause you to crave energy dense/high calorie foods because, again, your body thinks it needs lots of energy to handle the stressor.
  3. Inflammation – Inflammation is a natural way the body protects and heals itself, but excess inflammation can cause weight gain and increased risk for chronic disease. Sugar, saturated fat, and trans fat are all pro-inflammatory foods (aka the bad guys), and more and more studies are showing dairy, artificial sweeteners, chemical food additives, and white flour are also culprits of inflammation. This means that even if you are only eating 800 calories per day worth of these foods, you are unlikely to lose weight (and you might also find yourself with headaches, fatigue, joint pain, and increased risk for heart disease and cancer).

While I am the nutrition guru and wish that all problems could be solved with nutrition, it is important to remember that there are other factors that control our weight and overall health. Try getting an extra hour or two of sleep, doing some relaxing activities (like yoga, reading, listening to some music, or taking a walk outdoors), and cutting out some of the pro-inflammatory foods and see how you feel. You might be surprised by the results after just one week!

What is Healthy?

It has officially been a week since arriving in Copenhagen and I only went the wrong way on the train once! Last week was filled with orientation seminars and tours of the city, and I successfully survived my first day of classes on Thursday. So far, I am enjoying all of my classes with Danish definitely being the most difficult. Thanks to my host family, I’ve got built in tutors for that!

My core class in the Public Health program is Health Delivery and Prioritization in Northern Europe. Our class discussion on Thursday and our homework for the weekend revolved around the definition of health. Think about it… health can be a hard word to define. After reading this excerpt from Stephen Holland’s book Public Health Ethics, I was reminded of a new meaning of health that is often overlooked.

“…raised blood pressure is a risk factor for all kinds of disease. Reducing alcohol intake can be expected to lower the patient’s blood pressure and therefore reduce the risk of disease. So, the doctor ought to persuade the patient to drink less. But, on a conception of health as well-being, things look different. Given the patient’s circumstances, it might well be that going to the pub or bar to drink beer is vital to maintaining the levels of well-being. Stopping drinking – even compromising the pleasure of drinking by harping on about its detrimental effects – might well be disastrous for the patient’s well-being. So, on this account of health it would be dubious of the doctor to persuade the patient to drink less.”

The World Health Organization defines health as “a complete state of physical, mental, and social well-being, and not merely the absence of disease or infirmity”. Coming from a nutrition perspective, I am always focused on physical health and preventing disease and often forget about the mental and social well-being part of health.

So what is the point?
What I am trying to say is that it is important that we enjoy what we are eating and have a positive relationship with food. Eating lots of fiber, vegetables, and lean meats is great for our physical health but sometimes it can be overwhelming and interfere with out mental and social well-being.

For example, if you are at a dinner party or a restaurant trying to eat only “healthy” foods, the “unhealthy” foods around you can be very tempting. This can cause anxiety and an unpleasant, stressful night for you. You might be proud of yourself at the end of the night for not having a single French fry, but was it worth all of the anxiety? Would it have been better for your mental and social well-being to have a few fries or a bit of ice cream?

Not only is your diet about balance, but so is your overall health. Every person is different so I am not going to tell you when and where you should be eating what, but keep in mind that your overall health is determined by a lot more factors that just the food that goes into your mouth. Making “healthy” choices doesn’t just mean eating salad for every meal. “Healthy” choices can also include having a piece of cake in honor of a celebration or having chips and salsa at the dinner party so you don’t feel isolated and hungry.

5 Tips: Adjusting to the College Dining Hall

As the new school year rolls around it is out with mom’s home cooked meals and in with all-you-can-eat dining halls. Going away to college calls for new eating habits, which can definitely add to the stress of moving away from home. With many assignments to be completed, textbook pages to read, and tests to study for, food should not be on your list of things to stress about while away at school.

I struggled to find healthy and yummy options my first semester of college. After lots of trial and error, I discovered these 5 tips are the best way to take the stress out of eating in a college dining hall.

  1. Ask about allergens or special diets. If you have any allergies or a special diet, make sure you contact the catering company that provides to food to your dining hall. They likely have a dietitian on staff that can help you find foods that are safe for you to eat.
  1. Become friendly with the chefs and other kitchen staff. From my experience, they love talking to students, and if they know who you are, they will be more likely to get you what you want (even if it isn’t on the menu for the day).
  1. Find a “go to” food item the dining hall always has and that you enjoy. My dining hall always has a salad bar and a stir-fry station, so no matter what they are serving I know that there is always something for me to eat.
  1. Fill out the comment cards. Most dining halls will have a place in the dining hall or online where you can leave comments and suggestions. If there is something you liked or didn’t like, tell them. If there is something that you would like that they don’t have, tell them. From my experience, the chefs and dining hall staff take them seriously and will often respond to you.
  1. If you can’t find anything you like, ask! My school has a “just ask” policy; if you don’t see it, find a chef or other staff member that can help you. Lots of times, if you wait a few minutes they will make you what you want, as long as they have it in the kitchen. If the on-site staff is not responsive to your requests, contact a manager or dietitian. They should do their best to get you what you need and feel comfortable with your food options.

If these tips don’t work, try again (and again)! Seriously, don’t be afraid to advocate for what you need. Nobody can live without food so you might as well enjoy what you are eating.
