Nutrients

You've heard the word or at least seen it - nutrient.  What is it exactly?  Obviously, it has something to do with nutrition - right.  Nutrients are, basically, chemicals derived from food that our bodies use for energy, structural materials (bone, etc.), and regulating agents for growth, maintenance, and tissue repair.  Hmm, pretty important stuff those darn nutrients.  Nutrients are broken down into various categories, depending on what is being discussed:

  • Macronutrients are those nutrients that our bodies need in large amounts such as carbohydrates, fats, and proteins (macro=large);
  • Micronutrients are the nutrients that our bodies need in smaller portions such as vitamins and minerals (micro=small);
  • Essential nutrients are nutrients (chemicals) that we require from outside our bodies.  In other words, our bodies can't produce them or we produce them in too small quantities to meet physiological needs -- there are approximately 40 essential nutrients, by-the-way;
  • Organic nutrients - no, not like organic produce but it relates to the nutrients that contain at least 1 carbon molecule.  These are the vitamins of which there are 13.
  • Inorganic nutrients are nutrients that do not contain any carbon molecule.  These are the minerals and there are only 16 of them that are known to be essential in human nutrition.
Now that we have all of that cleared up, I'd like to discuss these nutrients :D  You knew that was coming, right?  Right.

There are six classes of nutrients required by our bodies.  They are:
  1. Carbohydrates - macronutrient; provides energy; organic
  2. Lipids (aka fats) - macronutrient; provides energy; organic
  3. Proteins - macronutrient; provides energy; organic
  4. Vitamins - micronutrient; organic
  5. Minerals - micronutrient; inorganic
  6. Water - inorganic
 NOTE: There are other compounds in foods that our bodies utilize (fibers, phytochemicals, etc.) but these are not considered nutrients...just wanted to clarify that.


Macronutrients. When the body uses carbohydrates, fats, and proteins for energy or fuel, the bonds between the nutrient's atoms break and releases the energy into our bodies.  Some of the energy is released as either heat or it's used to send electrical impulses (messages), to synthesize body compounds, and to move muscles.  If either of these macronutrients is not used up in the body, what do you think happens?  Yep, it gets stored in the body for some day in the future when the intake is inadequate or during the night while you sleep or even for in-between meals.  Speaking of which, your body continues to use energy (your brain especially) while you sleep therefore depleting stored reserves and helping you to lose weight - that's why it's so important to get enough hours of sleep if you're trying to lose weight!  And, did you know that our brains (since we've sidetracked a bit about that fine organ) use glucose for fuel and that our bodies produce that from the carbohydrates we eat?  The only animal product that has enough carbohydrates for this are dairy products...take that, Atkins dieters. Click here to learn more.  These same macronutrients (carbs, protein, & fats), also provide the foundational materials to build tissues and regulate many of the body's activities/functions. (FYI - Protein is NOT a major energy provider but is more of a structural building block. It also helps to regulate digestion and metabolize energy.)
 

Vitamins. Obviously, vitamins don't directly provide energy to the body but they do play their part. These little (micronutrients) powerhouses help the macronutrients release their energy and they do a bunch of other things throughout the body too.  Each of the 13 vitamins has a starring role in the body because almost every action in the body requires the help of vitamins.  Also good to know - vitamins can only function properly if they are intact.  Their molecular organic complexity makes them vulnerable to being destroyed by heat, light, and chemical agents!  This is why steaming veggies for a very short time (or eating them raw) is a preferred and healthier method of preparation.  Just for fun, here are the 13 vitamins: 
  1. Vitamin C (water soluble);
  2. Eight (8) B vitamins (water soluble) - thiamin, riboflavin, niacin, B6, B12, folate, biotin, and pantothenic acid;
  3. Vitamin A, D, E, & K (fat soluble).
 Minerals. These also don't fuel the body's energy needs but they are important to the body's structures.  There are only 16 known essential minerals in human nutrition, even though they are studying others to figure out if they have a significant function.  Being inorganic, minerals are pretty much indestructible but they can bind to other substances that might get in the way of the body being able to absorb them.  They can also be lost during food-refining processes or when cooking because they seep into the preparation water that is thrown out. Major minerals are equivalent to macronutrients in that they are needed in large amounts and trace minerals are needed in smaller amounts.
  1. The major minerals are: calcium, phosphorus, potassium, sodium, chloride, magnesium, & sulfate.  For more information on the major minerals, go here.
  2. The trace minerals are: iron, iodine, zinc, chromium, selenium, fluoride, molybdenum, copper, & manganese.  To learn more about trace minerals, go here.
 Water.  Everyone has heard of how important water is to the proper function of our bodies, right?  It must be really important if a 150lb body contains about 90lbs of water! It's used in metabolic reactions, helps transport vital materials to cells, helps carry away cell waste products...it's really important.  We can go (on average if we're healthy) about 8 weeks without food but we can die in a matter of hours without water.  

So, drink your water and make sure you're getting all of your nutrients!

Health Claims on Food Labels (in USA)

Did you know that up until 2003, the FDA (Food and Drug Administration) would make food manufacturers show significant scientific evidence of any health claim they wanted to put onto their product labels?  Yes, I said "up until 2003" because after that, things got stupid and crazy.  Once again we get to see evidence that these manufacturers, those with the "deep pockets", get to play havoc with the public's psyche.

Before 2003, if a food label read "Diets low in sodium may reduce the risk of high blood pressure" we would have known that this couldn't have been published on the label without having enough scientific evidence to back it up - the FDA wouldn't have allowed it. Back then, if there was a claim on something, it came with scientific baggage.

Okay, let's get clear first on what exactly is a "health claim".  According to the FDA, a health claim is: "any claim made on the label or in labeling of a food, including a dietary supplement, that expressly or by implication, including “third party” references, written statements (e.g., a brand name including a term such as “heart”), symbols (e.g., a heart symbol), or vignettes, characterizes the relationship of any substance to a disease or health-related condition. Implied health claims include those statements, symbols, vignettes, or other forms of communication that suggest, within the context in which they are presented, that a relationship exists between the presence or level of a substance in the food and a disease or health-related condition (see 21 CFR 101.14(a)(1)).
Further, health claims are limited to claims about disease risk reduction, and cannot be claims about the diagnosis, cure, mitigation, or treatment of disease. Health claims are required to be reviewed and evaluated by FDA prior to use. An example of an authorized health claim, is: 'Three grams of soluble fiber from oatmeal daily in a diet low in saturated fat and cholesterol may reduce the risk of heart disease. This cereal has 2 grams per serving.'"


Yes, well...it all started with supplements and then the GMA (Grocery Manufacturers Association) decided that they didn't want to be left out in the cold so they challenged the FDA saying that if they didn't get the same treatment that was allotted to the supplements industry in the Pearson ruling that they would also take the FDA to court.  The gist of the argument was that the GMA should be allowed to inform their consumers of possible benefits.  The court ruling read, "Holding only the highest scientific standard for claims interferes with commercial free speech".

In order to accomplish this, while still letting the public know what their stance was on the particular health claim, there was devised a plan...a letter grading policy.  Have you heard about it?  I hadn't until recently because, basically, if I saw a product that read "...has been shown to lower cholesterol", I was assuming it had been scientifically proven and okayed by the FDA.  As far as I can tell, there's no actual letter grade printed on packages but it's the way a claim is worded that's supposed to tell us what the grading is. Uh...what?

Do you know what the grading policy is exactly? Here's an ABC/Health News article from that time that excitedly shares the information and cites a lot of experts that were excited for the change and those that were not. I have to side with the "were not" ones, especially when they said that consumers wouldn't pay attention to the letter grades but just the health claim. Really?  You think??  Let's face it, as human nature goes, we're far too busy to read the nutrition label AND follow up on the health claim grade too, right?

In case you do want to know but only want the highlights, the grading policy goes like this:
Grade A: High: Significant scientific agreement - no disclaimer needed.
Grade B: Moderate: Evidence is supportive but not conclusive - must have this statement after the health claim: "Although there is scientific evidence supporting this claim, the evidence is not conclusive."
Grade C: Low: Evidence is limited & not conclusive - must contain this statement: "Some scientific evidence suggests [enter health claim here]. However, FDA has determined that this evidence is limited and not conclusive."
Grade D: Very low: Little scientific evidence supporting this claim - must have this statement: "Very limited and preliminary scientific research suggests [enter health claim here].  FDA concludes that there is little scientific evidence supporting this claim."

Okay, so I just checked out my box of Kashi Lean cereal and snapped a picture of their health claim:
So it says "25 grams of soy protein a day, as part of a diet low in saturated fat and cholesterol, may reduce the risk of heart disease."  There's none of those other disclaimers on there so we can assume that this health claim has an "A" grade, meaning there's "significant scientific agreement" to their claim! Whew! That's good to know, 'cause I just had some for a snack :-D   I was looking for a different claim but couldn't find any in my pantry - guess that's what I get for buying healthy foods.

Besides these "health claims" on packages, there are other claims that are completely different categories - nutrient claims and structure-function claims.


Nutrient claims are those phrases like "good source of fiber" or "rich in calcium" or "low in sodium" because they single out a particular nutrient to focus on for marketing purposes (of course).  It works though, doesn't it?  If you know that eating more fiber helps you lose weight and lower your risk for heart disease, when you see that tag "good source of fiber" or "high in fiber", you'll be tempted to grab it, won't you? Still, these have to meet FDA definitions, and let me tell you that there are A LOT of definition guidelines for these claims!  Let's take my fiber example - "good source of fiber"...in order to claim that on the package the product must provide between 10% - 19% of the Daily Value for fiber, per serving.   But change the claim to "high in fiber" and then the product needs to be 20% or more of the Daily Value for fiber per serving (this goes for the words "rich in" and "excellent source" interchangeably).  Ya, words - who knew that just changing the words "good source" to "high" would mean a difference in the amounts of a particular nutrient?  Oh, and just so you know, the words "fat-free" aren't 100% true -- something can say that it's "fat-free" and still contain up to .5grams of fat per serving...eat 5 servings and that's 2.5 grams of fat...not that it's all that much, but fat is fat, is fat... If you want more information on the wordings and what you're really getting, you can go to the FDA labeling website by clicking here.

Structure-function claims are the most unusual of the lot - hold on to your hats for this one -- they can be made WITHOUT any FDA approval!  These claims can be made WITHOUT any proof - none, zip, nada!   The only requirement is that the claim cannot mention a disease.  Look at the following statements:
A) "May reduce the risk of heart disease."
B) "Promotes a healthy heart."
Statement (A) is definitely a health claim whereas statement (B) is a structure-function claim - can you tell the difference?  If you saw statement (B) on a box of cereal, would your thought be "This might prevent me from having a heart attack - I think I'll buy it"?  Or would it be "Huh, there's no actual health claim here maybe I should look for a cereal that does have an actual heart disease prevention health claim"?  Honestly, consumers don't usually know that there's a difference.  I sure as heck didn't know.  Here's the link to the FDA's information on structure-function claims if you want more information.

So, now that I've shared all of this information with you, what are you going to do with it?  I hope you share it with those who are close to you.  There's more to reading labels than just reading the nutrition panel and, as much as I hate to think about it this way, there are big, money-making food manufacturers out there to make even more money and to trick you into buying their products by using the laws to their advantage.  Make an effort to beat them at their game by getting educated on what it is you're putting into your body because food, whether you want to think of it that way or not, is a chemical - and there are bad chemicals and there are good chemicals (there are some that are the Switzerland of chemicals but that's another story) so fuel your body with "premium unleaded" food instead of "regular" almost-food products.



Hahaha!  Here's MY disclaimer now:

RECIPE - Dark chocolate pudding!!

Oh ya, and it's VEGAN!!

Serves: 4


TOOLS NEEDED:
- A small, seal-able container for 1/4cup of liquid.
- Dessert dishes (4)


INGREDIENTS:
1/2 cup evaporated cane juice sugar
1/2 cup baking dark cocoa (powder & preferably organic)
1 tbsp non-GMO cornstarch (or use arrowroot instead)
1 1/4 cup unsweetened almond milk (you can use soy or vanilla flavored but that will change the nutrition information)
1/4 cup unsweetened almond milk
1 tbsp vanilla extract
Pinch of salt

DIRECTIONS:
1. In a saucepan over medium-low heat, whisk the sugar, cocoa, and 1 1/4 cups almond milk.
2. While mixture is warming, add the cornstarch and 1/4 almond milk into the small, seal-able container; shake until well blended. Set aside.
3. When the sugar, cocoa, milk mixture is simmering, open cornstarch container carefully (slowly) whisk the mixture into the saucepan.  If you do it too quickly, you will get clumps of chocolatey cornstarch (which isn't really all that bad but it won't be smooth).
4. Continue whisking until mixture starts to thicken; remove from heat and pour immediately into dessert dishes.  Let them cool before covering with plastic wrap then store them in the fridge.
Enjoy!!

Motivational & Self-Help for Everything!

I am about to push...er, recommend a book to the universe (or at least anyone who reads this blog :D ) but, before I do that, I've got to do a build-up first or this might be a pretty boring post.

Some of you might be aware that I decided to finally start watching "The Biggest Loser" show this coming new season (BTW, which premieres on Tuesday, September 20th!) but I like to get caught up with any show I decide to watch that's been on for a while.  So onto Hulu I went and all the way back to the very first episode of the show.  As I first started watching those episodes back-to-back, I really could NOT stand Jillian Michaels! Seriously.  I thought she was mean and thoughtless and too severe (especially in contrast to Bob Harper's style which has also changed a lot from the beginning of the show). But then something happened.  Slowly, I started realizing that she had a really great psychological understanding of why people get to that "Biggest Loser" stage in their lives.  She doesn't take very long to realize what their triggers are or what the "chinks in their armor" are and then she digs in - very much like a doberman but the hurt is going to make those people (hopefully) realize what their issues really are and make them bring out those issues into the light of day.  Breaking someone down so they can build themselves back up!  It's brilliant!  Well, I think she uses her abilities brilliantly :D  Yes, even when she's yelling & insulting them as they sweat buckets to endure the physical side of her technique.  But, I believe, she does it to bring out what needs to be brought out by removing barriers, making them so raggedly tired that there's no energy left in them to fight back and keep their emotional walls up.  Now, mind you, I'm not saying that I know how she thinks or anything but all of this has just been small observations as I progressed through the numerous episodes that I watched over the Summer.  I'm also not about to start worshiping her (even though I believe there is a goddess in every woman) or anything but I can acknowledge that she knows her stuff AND not just weight loss, dieting, and exercise!  

Fast forward to a few weeks ago.  I was tired of listening to music during my workouts so I decided to download a few motivational audiobooks.  I tried one and found that I had much better focus during my exercise routine than when I listened to music.  I went on to a second audiobook but didn't really care so much for it. I went back online to find something else for my next workout.  As I was scrolling through some "same ol', same ol'" types of motivational books, I had an idea and decided to search for something written by Jillian Michaels, thinking a fitness motivational audiobook would be really cool.  But, it wasn't her fitness books that caught my eye.  It was another book she released earlier this year called "Unlimited: How to Build an Exceptional Life"  I downloaded it and I haven't regretted it one single bit!  If you get your hackles up at the mention of something written by Jillian Michaels, let me just say this to you: Open your mind and give her book a chance because it is profound!   It's very much her personality in the sense that it's "no holds barred" and she uses strong language on occasion to get an important point or two across but it's well organized with information and ideas that JUST MAKE SENSE!  The audiobook makes me feel like she's really standing there, next to me (or jogging alongside me) and talking to me like a very emotionally intelligent (& mentally intelligent) friend who's giving me her sage advice.  For example, why do some of us feel guilty if we acquire something we've wanted/desired for a long time?  Why do we feel guilty about having wants & desires for something more than what we have?  Do you want to know what her take is on this concept? Get the book! Oh wait, you know what?  Please get the book and read it - let your mind be open to see the possibilities because what if the way you've been thinking and doing things has given you the same undesired results repeatedly, does that mean the next time you try doing or thinking the same way it'll work out better? If you believe that, then please don't get the book :-)

So, with that said - love her or hate her, you know she helps people get results and achieve their goals, and not just with weight loss and exercise.  I read a lot and, honestly, there have been only two books up until now that have helped me be a better person emotionally and have helped me find my paths in life - this book will definitely be the third on that list (scroll to the end if you want to see my list). Get this book - read it or listen to it then go back and do it again & do the exercises the second round - that's what I'm doing (a little difficult to write answers down when you're trotting along on a treadmill or on the pavement)! 

Thank you, Jillian Michaels, for writing something so perceptively right! 

My emotional & life path changes have been transformed for the better by the following books:
1) Living with Joy, by Sanaya Roman (yes, it's a new age, spiritual book but it made me realize how much of my life's reactions are my own choice);
2) The Journey of Souls: Case Studies of Life Between Lives, by Michael Newton (this was the first time that I felt I had learned the truth of our existence, it FELT right);
3) Unlimited: How to Build an Exceptional Life, written by Jillian Michaels (this is just an addition to everything else I've learned about myself, the universe, and life)

RECIPE - Lower Calorie Tapioca Pudding!

I loved tapioca pudding when I was a kid and still do but I've never liked the name-brand, pre-made versions at the grocery stores -- they're too watery for me.  My grandma used to make tapioca pudding so that it was thick and, I hate to say it, almost a rubbery consistency.  But that's how I remember tapioca and that's how I like it.  Now, being on a vegan diet, I've been experimenting with different mixtures to get a tapioca pudding that I can enjoy but that will deliver less calories and maybe add more nutrients than a plain tapioca pudding.  So, tonight, I think I've found it!  Here's my discovery - drop a comment if you try it!  My next experiment will be vegan cannoli so that when my daughter is eating one, I can eat one too! :D

Vegan Tapioca Pudding Recipe
Serves: 4
(CalorieCountAbout.com)
  

SPECIAL EQUIPMENT
4 – dessert bowls

INGREDIENTS
½ cup of quick cooking granulated tapioca (I like Let’s  Do…Organic brand)
½ tsp vanilla extract
¼ tsp cinnamon
1 ½ cups unsweetened soy milk
¼ cup evaporated cane sugar
½ cup unsweetened applesauce
½ cup unsweetened almond milk

DIRECTIONS
  1. In a medium saucepan, add all the ingredients. Whisk together.
  2. Place saucepan over a medium-low heat.
  3. Whisk constantly to prevent scorching and the tapioca from sticking to pan.
  4. When tapioca has thickened (remember that it’ll thicken and solidify more when it starts to cool) to your desired consistency, turn off heat.
  5. Pour into dessert bowls and let cool, then cover & store in fridge.
