Food Science in the News: Taco Bell debuts new Power Protein Menu July 25th 2013


Ringing Endorsement for Protein: Taco Bell's new Power Protein Menu (coming to select locations July 25th) 
New items on the Power Protein Menu include a Power Protein Burrito and the Power Protein Bowl. Each item includes the word "power" to portray the connection between protein and performance. But as a wise man once explained to his grandson, "With great power comes great responsibility." Let's look at the pros and cons of these Power Protein meals.

Pro: Getting enough protein every day is important for overall health
Amino acids are the most basic unit of proteins, just as letters are building blocks to words. When amino acids are linked together in certain ways, they build proteins that perform several important functions in the body. Blood clotting, fluid balance, hormone production, cell repair – all rely on a steady source of amino acids so the body can build the protein that will get the job done.

Pro: Getting the right kinds of protein is essential to life
The body makes about half of the amino acids it needs, but some of them (the "essential amino acids") have to come from the diet. If one amino acid is missing, it's like building a car without a steering wheel. You need all the pieces or it's a no-go.
The Power Protein burrito and bowl each include double-servings of chicken or beef, animal sources of protein which are considered "high-quality" or "complete" proteins because they contain sufficient amounts of all the essential amino acids. The Power Protein bowl also comes with slow-cooked black beans, which are a great source of the amino acid methionine. Fingers-crossed there'll be a Power Protein Black Beans and Rice bowl – complementary proteins that would give vegetarians all the essential amino acids.

Con: You don’t need as much protein as you think
It's true that protein deficiency can lead to weakened immune system, edema and diseases like Kwashiorkor, but an excess of protein can put stress on the body too. The typical North American diet has no shortage of protein. The protein RDA for adults is 0.8 grams of protein per kilogram of body weight, which means a man weighing 154 pounds only needs about 56 grams of protein. For most athletes, 1.2 grams of protein per kilogram of bodyweight is enough for muscle maintenance and growth, and few studies prove that a higher ratio than this increases muscle growth. Some fitness professionals recommend up to 1.7 grams of protein per kilogram body weight but at that ratio amino acids get used for fuel.

Con: Yes, you can have too much protein
If your body could talk, it would tell you that using protein instead of carbs for fuel is annoying. It's almost as annoying as getting rid of a Christmas tree or your X's belongings. You have to take it somewhere special and dispose of it properly. It's a hassle. The liver and kidneys have to take extra steps to remove nitrogen and process all the other accessories like sulfur. The body can do these steps, sure, but here's the problem: the body stores fat, the body stores carbs, the body does not store proteins. That means when there's an excess of protein in the body, the situation has to be dealt with immediately – not unlike a crying baby, a barking dog or an overflowing toilet. See? Annoying.

Pro: A meal high in protein is satiating; it satisfies hunger and keeps one feeling fuller, longer
As a result of the way proteins are metabolized, they satisfy hunger more than carbs alone. The body runs on carbs as the #1 source of fuel so it's incredibly efficient at metabolizing them (exception: dietary fiber, which isn't absorbed). Nutrition experts recommend adding a bit of protein to every meal because it's more metabolically satisfying than carbs or fats.

Con: Dinner isn't supposed to be the biggest meal of the day
Eat breakfast like a king, lunch like a prince and dinner like a pauper. That saying by American author and nutritionist Adelle Davis has been scientifically proven time and again. Breakfast is important. Those who skip it usually gain more weight over a year than those who do have breakfast. Metabolism is more efficient in the morning than at night, so a big breakfast kick starts the day while a big dinner has a higher likelihood of being stored. A hearty meal late at night with tacos, multiple Power Protein Burritos, nachos and a giant soda won't increase power as much as it'll increase the waistline.

Pro: Power Protein Menu items have more than 20 grams of protein but fewer than 450 calories
Sure, Taco Bell may be capitalizing on the high-protein craze (or as some dietitians call it, "Atkins, revisited"), but these menu items actually have potential to help people eat better, healthier meals (as long as people don't go crazy and order multiple items from this menu).
Protein – good.
Quality protein – good.
Less than 450 calories per meal with over 20 grams of satisfying protein – GOOD!

Energy Drink of the Month - July 2013

Partially inspired by the movie Iron Man 3 and partially due to this summer's hot weather, I've chosen Nawgan Mandarin Orange as the Energy Drink of the Month for July 2013.

For any caffeinated beverage, the following 10 attributes are key to assessing the drink's potency and value. Let's go through this exercise with Nawgan's Mandarin Orange.





1. CAFFEINE CONTENT:
Caffeine content is stated on the label - 100mg caffeine per can (11.5 ounces)
This is amount is less than the amount of caffeine in a tall iced coffee from Starbucks (120mg).
 Energy Fiend Complete Guide to Starbucks Caffiene

2.  SERVING SIZE AND SERVINGS PER CONTAINER:
One serving is one whole can, which makes it easy to regulate the amount of caffeine one consumes.

3. NUTRITION OR SUPPLEMENT FACTS PANEL:
This product has a Nutrition Facts panel, which means it's a beverage, not a supplement. That means this product is subject to food/beverage regulations, not the supplement reglations (What? Supplements are regulated? Yes, despite what you may here elsewhere, supplements ARE regulated by the FDA, just using a different rule book than the one used for food/bev products).
Since this has a Nutrition Facts panel, you know all the ingredients used within are either GRAS (Generally Recognized As Safe) or approved food additives.


4. RECOMMENDED USE:
Since this product is a beverage, not a supplement, it's unusual to find Recommended Usage or Warning information. Some caffeinated beverages still bear the Warning Label, but this beverage does not. With only 100mg caffeine, this isn't surprising.

5. FIRST INGREDIENT:
The first ingredient in this product is filtered water, not carbonated water. Carbonation irritates the stomach lining which speeds up the absorption of certain molecules like alcohol and caffeine. This is why champagne seems to affect one's sobriety more rapidly than beer does.

6. SWEET STUFF:
This product has 11 grams of added sugar so those of you watching your sugar intake may want to opt for the sugar free Nawgan products.  This product also has Erythritol, a sugar alcohol that's captured the interest of food scientists for its reported ability to improve oral health.
New clinical trial indicates erythritol’s superior dental benefits
Notably, this product is also sweetened with Stevia, not any artificial sweeteners.

7.  VITAMIN B-12:
Vitamin B-12 plays a key role in maintaining healthy cells and DNA throughout the body. This product has 50% of the Daily Value of B-12, a respectable amount. There is no known upper intake level for B-12, meaning you can't ever have too much, but there's no reason anyone without a clinically diagnosed B-12 deficiency or absorptive disorder needs over 100% DV in one product.

8. VITAMIN B-6:
 Vitamin B-6 participates in over 100 chemical reactions in the body, most of them involving amino acids and proteins. This product has 50% of the Daily Value of B-6, which is a good amount. A deficiency in B-6 makes it harder for blood cells to carry oxygen properly, so it's important to get enough of the vitamin every day. However, intakes over 100 milligrams ( 5,000% DV) can cause nerve damage.

9. FOLIC ACID - This product has no folic acid, which isn't a bad thing at all. It would only be bad if the product had more than 100% DV folic acid, because that could mask a B-12 deficiency.

10. NIACIN - This product has no niacin, which isn't a bad thing either. It would only be bad if the product had more than 35 milligrams of niacin (175% DV) because that could bring on the "niacin flush" - symptoms of flushing and itching.

BONUS POINTS:
This drink gets bonus points for the ingredient that makes it (and all other Nawgan beverages) special. Citicoline has been used in numerous studies assessing cognitive health and especially cognitive decline with diseases such as Alzheimer's disease. A double-blind, placebo controlled (aka legit) study involving healthy participants showed that daily supplementation with citicoline improved cognitive function and performance. That study can be found here:
Improved Attentional Performance Following Citicoline Administration in Healthy Adult Women


BOTTOM LINE:
The amount of caffeine in this product and the lack of carbonation make this product a good match for Fatigue Level 3 (Read more about the 5 Levels of Fatigue in my book, ARE YOU A MONSTER OR A ROCK STAR: a guide to energy drinks - coming August 2013).

This drink is perfect for those mornings when a cup of tea or a glass of water isn't enough to wake you up, but you don't need a high-powered shove of caffeine to push you through an all-nighter or a graveyard shift. Moreover, whether or not this citicoline brain-booster actually works, the drink is energizing, sweet and refreshing - perfect for a hot summer day.

"That was brave" versus "I wonder if..."

What is it like to step up to the plate, hoping you get to be the hero and hit the home run that wins the game while fearing you will swing and miss, thereby bringing shame not only upon yourself, but upon your family, your fans and your whole team?

What is it like to tell someone you've fallen for them without knowing where they stand or how they truly feel about you?

What is it like to stand up in front of a crowd of strangers and open your lips to deliver a song or a speech you've been practicing and perfecting for months on end?

These scenarios are just a few examples of what it's like to pit vulnerability and fear against passion, drive and commitment. If you don't try at all, you won't fail, but you won't succeed either. If you never fall for anyone, you'll never get hurt, but you'll also never know true love. If you never stand up in front of a crowd of strangers, you'll never face the ridicule of people who don't enjoy your material, but you'll also never know the satisfaction of truly connecting with your audience.

"The safest risk is the one not taken" goes a popular motto in the field of Quality Assurance. But without risk, there is no reward. A quest to ensure safety is hardly a quest because the only way to stay safe is to take no action at all. This dichotomy is captured in Finding Nemo:

Marlin: I promised I'd never let anything happen to him. Dory: Hmm. That's a funny thing to promise. Marlin: What? Dory: Well, you can't never let anything happen to him. Then nothing would ever happen to him. Not much fun for little Harpo.

On a personal note, fear has dominated much of my teenage years and I suspect fear was what really ended my gymnastics career, not the knee injury - one brought about the other. As I grow older I am getting better at following the mantra, "I'd rather say 'WOW, that was brave' than 'I wonder if...' ". At times it can be excruciating to act upon my curiosity and drive instead of obliging my fear. But often the first step is the hardest, and the satisfaction of actually taking action is much more rewarding than the satisfaction I'd get if I played it safe and never tried.

Maybe I won't be remembered as being the smartest or greatest, and I will probably always be a little cautious and analytical, but I would also like to be remembered as being brave.

Bold takes initiative.
