The Truth about Vitamin D, Sunshine, & Supplements

The Truth about Vitamin D, Sunshine, & Supplements

If you’re like me, I find it a challenge to figure out what amount of vitamins I need, and whether or not I get enough of them in my diet.  Vitamin D is one that I have been most confused by, especially because some believe it is best to obtain it from the sun, and yet we are also warned of the damages of the sun.

Well, most medical professionals agree that between 30-80% of Americans are actually vitamin D deficient.  Clearly there are many of us who are confused!  Unfortunately, individuals with low vitamin D levels have a higher risk for developing many health issues, including autoimmune diseases and cancer.  Vitamin D assists our bodies in the absorption of calcium, which helps us develop stronger bones, and helps to prevent or slow osteoporosis.  Research has also shown that vitamin D also strengthens the immune system, and may also decrease our risk of hypertension and psoriasis.

If you’re interested in learning if you are Vitamin D deficient, the National Institute of Health feels the best measure of one’s vitamin D status is blood levels of a form known as 25-hydroxyvitamin D.  You can ask your doctor to check your levels through lab work.

Dr. Andrew Weil (www.drweil.com) recommends that we get 2,000 IU of vitamin D daily.  The National Institute of Health recommends that children from birth to age five should get 200 IU daily.  If you are going to take a vitamin D supplement, vitamin D3 is the best to take.  However, getting appropriate levels of sunshine is far better, provided you do it safely.

Below is a chart that describes how much sunshine you need daily, if you’d like to get your vitamin D this way, depending on skin type. The chart identifies adequate amounts of vitamin D, based on your local UV index.  Please keep in mind, however, that sunscreen blocks our bodies’ ability to synthesize vitamin D.  An SPF of 8 inhibits our ability to make vitamin D by 92.5%, an SPF of 15 inhibits it by 99%. Therefore, skip the sunscreen when following the guidelines offered in the chart below.  (Stats source: http://www.tcolincampbell.org/courses-resources/article/dispelling-vitamin-d-myths/?tx_ttnews%5BbackPid%5D=76&cHash=8b49fbe90a70ed9ccc5355403ffc7091)

Here’s a link to the Environmental Protection Agency that you can use to determine your local UV index based on your zip code: http://www.epa.gov/sunwise/uvindex.html

It’s important to remember that excessive sun exposure does lead to skin cancer, and sunburns can also be quite painful, so if you are going to be outdoors for any longer than what the chart and UV index identifies as being safe, please use sunscreen and protective hats and clothing.  Dr. Weil recommends an SPF of 30 or higher, and one that protects against UV A (causes sun damage and wrinkling) and UV B (causes sunburns and skin cancer).  It’s important to apply the sunscreen 15 minutes before you go outside, and reapply it every two hours.

Excessive sun exposure does lead to skin cancer, however safe, appropriate levels of sunshine can actually lead to good health.  As with many things, we have to find a healthy balance between the two.

Please, don’t forget- good health is contagious, please pass it on!    

How to Select Healthy Foods While Food Shopping…

How to Select Healthy Foods While Food Shopping…

Hey blog peeps!  As many of you already know, I’m enrolled in eCornell’s Certificate in Plant Based Nutrition, and I’m currently taking “Principals in Practice,” the third and final class.  I just finished a lecture for my class titled “Label Reading,” and I wanted to share the highlights with you while it’s still fresh in my mind.  This was definitely one of the most useful, practical lectures yet.

The guest lecturer for this portion of our class was Jeff Novick, a Registered Dietician with 25+ years experience.  He taught us two rules and a few guidelines to follow when selecting food.  He also shared with us how food companies maneuver around the laws and mislabel foods regularly.  I’ll talk about the mislabeling of food in another blog post.  For now, we’ll focus on Jeff’s shopping tips…

We’ll start with Jeff’s two simple rules.  First, don’t ever believe the front of any product- regardless of what is says.  As an example, 1% milk has 24% fat and 2% milk has 34% fat. Who knew??? Well, thankfully, Jeff does.  How is this possible???  Well, as I just learned, the U.S. health guidelines recommend that we limit fat as a “percentage of calories,” while all of our packaged food list fat as a “percentage of weight.”  Confusing, I know.  (I’ll explain this in my future “mislabeling” post…)  Our second rule is to always read the ingredient list and the nutrition facts label.

And, now, onto the guidelines…  As usual, different people and organizations have varying views on what is ideal for our health.  As an example, the USDA and groups like the American Dietetic Association (ADA) and the American Heart Association (AHA) recommend 30-35% of total calories come from fat, while people like Jeff and Dean Ornish recommend that 10-15% of total calories come from fat.  For the lecture, Jeff merged the two sides and recommended that we aim for 20% for packaged products.  He also suggested that we raise or lower that percentage as we prefer, based on our health.  I’m going to aim for 20% right now.

So, the first guideline Jeff shared was to only purchase packaged items that contain 20% or less calories from fat.  As an example, a 100 calorie pack item would need 20 calories or less from fat.  A 200 calorie item would need 40 calories or less from fat.

The second guideline also involves fat- we need to check the ingredient list and avoid bad fats.  These fats fall into three categories- saturated animal fats (dairy, cheese, butter, lard, and chicken fat), saturated vegetable fats (palm oil, palm kernel oil, coconut oil, and cocoa butter), and man-made saturated vegetable fats (such as margarine, shortening, partially hydrogenated vegetable oil). Yes, he lists dairy, butter, and chicken fat as bad fats.  I know not everyone reading this is vegan or plant-based, or plans to be, but it’s good to avoid, or at least limit, these fats whenever we can.

The next guideline Jeff shared involves sodium.  If you’re in good health, most people need, at the very minimum, 250 milligrams of sodium daily.  The Institute of Medicine (IOM) recommends people up to age 50 consume no more than 1,500 milligrams daily, people ages 50 to 70 should limit it to 1,300 milligrams, and people ages 70 to 90 should limit it to 1,200 milligrams.  Apparently if you are over 90 years of age, you can eat however you want- something to look forward to!

The IOM also set an upper limit of daily sodium consumption at 2,300 milligrams.  They believe if you consume over 2,300 milligrams daily, you are harming your health.  Unfortunately, the average American consumes 3,000-5,000 milligrams of sodium daily, and only 10% of the sodium we consume is from what we add while cooking, or by sprinkling it on to our meals.  77% is from restaurant and processed foods we buy.

The third guideline involves using a salt to calorie ratio of 1:1, or less.  If an item has 220 calories, Jeff recommends not buying it if it has more than 220 milligrams of sodium.  If an item has 410 calories, he recommends not buying it if it has more than 410 milligrams of sodium.

Something you have to consider while looking at these numbers is the serving size.  The nutrition facts listed are per serving size.  If you think you’re going to eat two or three servings, then consider this when evaluating the numbers.

Now, we’re onto sugar, the fourth guideline.  First, sugar gets slammed an awful lot.  However, we need sugar, and it is one of our main sources of energy.  In fact, the average human brain burns approximately 500 calories of sugar daily.  The sugar that occurs naturally in fruits and vegetables isn’t typically a concern.  It’s the added sugars that are the problem for us.  Unfortunately, evaluating sugar in the nutrition facts is complicated, because the label lists total sugars, and we’re not interested in total sugars, we’re interested in added sugars.

So, this guideline requires us to look at the ingredient list.  Review the ingredient list for added sugars, such as honey, brown rice syrup, evaporated cane juice, and dehydrated honey.  Jeff recommends that if you’re really worried about avoiding sugars, then avoid any added sugars.  But, at the minimum, make sure added sugars aren’t one of the first three to five ingredients listed.

And, last but not least, the final guideline involves carbs.  90% of the carbs Americans consume is white flour, white rice, white pasta, and white sugar.  All of these have been refined, are stripped of their nutrients, and are high in calories.  On the other hand, Americans consume, on average, less than one serving per day of unrefined whole grains- a good carb.

Jeff recommends that we review the ingredient list again, and look for the word “whole,” and it has to be spelled like that too.  Examples would be “whole grain” or “sprouted whole grain.”  In addition, words like “rolled,” “cracked,” or “stone-ground” also typically means whole grains. 

In summary, these are the rules and guidelines we should be following in order to purchase foods and meals that will enhance our health, and not harm it.  I know some of them are easy, and others require a little math.  I’m going to begin using them when I shop.  I suspect it won’t be easy right away, but I am hoping that after a few weeks, I’ll get the hang of it.  If you try them out, please comment to this post, or comment on my FaceBook page, and let me know how it goes!  If you’d like to learn more about Jeff Novick, his website is: www.jeffnovick.com.

Back to school…and how I really do wish this was pie…

Back to school…and how I really do wish this was pie…

This cracks me up every time I see it...

For the last four weeks, I’ve been immersed in eCornell and the T. Colin Campbell Foundation’s Certificate in Plant Based Nutrition program.  There are three two-week classes in the program, and I’ve been taking them back-to-back.  I completed Nutrition Fundamentals two weeks ago, today I will wrap up Diseases of Affluence, and tomorrow I begin my last and final class for the program- Principles in Practice.  Once my third class is complete, I will have earned my spiffy new certificate.

If you’ve been wondering why I haven’t been writing as much these last couple of weeks, that’s why.  I tried on numerous occasions to write about the class for my blog, but I kept having trouble figuring out what to write about.  Please know it’s not due to a lack of information- quite the contrary.  I can’t even begin to tell you how packed this program is with useful information- much of it quite shocking and inspiring, all at the same time.  It’s taking some time to sort out how I want to write about it.

Before you think I am a vegetarian or vegan, please know I’m not.  I grew up eating the normal, standard American diet.  I have always loved vegetables and fruit, but I also enjoyed loads of animal protein, pastas, junk food, pre-packaged foods, frozen dinners, sodas, and fast food.  I’ve been trying to eat healthier over the last few years, and I thought I was finally making some progress.  Until…I saw a copy of the New York Times Bestseller, The China Study.  That’s when I started to rethink this whole food thing.

Turns out that the author of The China Study, Dr. T. Colin Campbell, is a professor at Cornell University, and he created the Certificate in Plant Based Nutrition program.  You may have seen him in the movie, “Forks Over Knives.”  I was interested in the program a while ago, but when I learned a couple of months ago that I could also knock out some of my continuing education requirements for my CHES certification, I signed up.  (To my fellow milspouses out there- the MyCAA program will pay for it too if you qualify.  And, I need to give a shout out to my friend Isheka who reminded me about the MyCAA program- thanks so much!!)

Boy, am I happy that I signed up…  As I’ve been learning, there are so many incredible health benefits to living a healthy lifestyle and eating a whole foods plant-based diet, and I plan to blog more about them throughout the coming months. Some of them include easy and healthy weight loss, having more energy, looking and feeling younger, lowering your risk of prostate, breast, and other cancers, preventing and reversing heart disease, vastly decreasing your need for prescription drugs, preventing and treating diabetes, keeping your bones strong, avoiding stroke, preventing kidney stones, lowering blood pressure, avoiding Alzheimer’s Disease, overcoming arthritis, and avoiding impotence, among many, many other benefits.  The best part is, if we cut out all the crap from our diets that we normally eat, we can eat as much as we want to.  There’s no counting calories, carbs, fat, etc.  We’d be eating real, whole foods, and plenty of it.

While I’m not a vegetarian or vegan right now, I definitely plan to move further towards a whole foods plant-based diet.  Also- just to clarify- the term vegan usually refers to individuals who don’t eat meat or dairy, and for many, a big motivation is how animals are treated.  A whole foods plant-based diet is very similar, but it identifies what to eat (actual fresh whole foods), instead of what not to eat (meat and dairy).  Technically speaking, vegans can eat processed foods, fast food, etc, as long as it doesn’t have meat or dairy in it.  Some don’t, but many do.

People who follow a whole foods plant-based diet eat very, very little meat or dairy, if at all (most do not), nor any processed foods, or junk food.  It doesn’t mean they can’t sneak a few chips or a burger in here and there, but generally speaking, this is how they eat.  They eat an incredibly nutritious and healthy diet.  I know it sounds like a huge leap from how many of us eat right now, but it’s totally do-able, and it is hardly boring or awful.  Believe me, I wouldn’t be interested in it if it were…

So, my apologies to my blog peeps for not writing as much as I had planned to these last few weeks.  But, please know my wheels are turning with loads of blog ideas, many of which are inspired by the certificate program.  And, I look forward to sharing this info with all of you.  After all, good health is contagious- and we need to pass it on!           

The Clean 15 & the Dirty Dozen

The Clean 15 & the Dirty Dozen

 

What needs to be organic, and what doesn’t…

We all know we should be eating our fruits and veggies, and a lot more of it, but buying fresh produce regularly can get pricey, and it can also be confusing.  I keep hearing mixed messages in the media about what produce to buy organic, and what “conventionally” grown produce is okay to consume.  Fortunately, I recently discovered the Environmental Working Group’s Clean 15 and Dirty Dozen lists.

The Environmental Working Group (EWG) is a non-profit that was founded in 1993.  Their mission “is to use the power of pubic information to protect public health and the environment,” per their website: www.ewg.org.  The EWG conducts research for consumers, including the “EWG’s Shopper’s Guide to Pesticides,” which is where the Clean 15 and Dirty Dozen lists come from.  This Guide ranks pesticide contamination for 53 popular American fruits and vegetables based on testing done from 2000-2009 by the FDA and U.S. Department of Agriculture.  Almost all of the produce tested were done so after they had been rinsed or peeled, and approximately 51,000 tests of produce were conducted.

The Clean 15 consists of fruits and vegetables that are least likely to test positive for pesticides.  In other words, you should be safe if you purchase these fruits and veggies “conventionally” (also known as “non-organic”).  The Clean 15 list includes: onions, sweet corn, asparagus, sweet peas, eggplant, cabbage, sweet potatoes, mushrooms, pineapples, avocado, mangoes, domestic cantaloupe, kiwi, watermelon, and grapefruit.

On the other hand, the Dirty Dozen list includes the most contaminated foods, and the EWG highly recommends only consuming organic versions of these fruits and vegetables, if at all possible.  The Dirty Dozen list includes: apples, strawberries, peaches, domestic nectarines, imported grapes, domestic blueberries, celery, spinach, sweet bell peppers, potatoes, lettuce, and greens (collards and kale). 

I was quite surprised while reviewing the Dirty Dozen on the EWG’s website, regarding just how contaminated they are.  Here’s some additional “food for thought:”

  • 97.8% of the apples evaluated tested positive for pesticides, and 92% of the apples tested contained two or more types of pesticide residues
  • 96% of celery samples tested positive for pesticides, 90% contained multiple types of pesticides, and one sample had 13 different chemicals on it
  • They found 14 different pesticides on one sample of imported grapes
  • All samples of imported nectarines tested positive for pesticides
  • Domestic grapes and strawberries had 13 different pesticides on one sample

So, the next time you are food shopping, remember that the Clean 15 should be safe if purchased conventionally, while you should consider buying organic versions of the Dirty Dozen.  To make things a little easier, here’s a link to a pocket-sized shopper’s guide of the lists: http://static.ewg.org/reports/2011/foodnews/pdf/2011EWGPesticideGuide.pdfAnd, please don’t forget- good health is contagious, pass it on! 

 

 

Today’s breakfast & my trusty juicer…

Today’s breakfast & my trusty juicer…

For the last four months, I’ve made a green juice at least five mornings a week- and I’m loving it…  Today’s recipe- cucumber, kale, pears, carrots (not green, I know), ginger, celery, romaine lettuce, and my secret ingredient to kill the excessive green taste- lemon.  My husband, who isn’t normally a fan of fruits and veggies, is even into it now.  Good health really is contagious- pass it on!
