Coffeeberry and Green Coffee Beans: Game Changing Ingredients for Energy Drinks

I declared myself a biochemistry/chemistry major in 2003 – right at the beginning of the Energy Drink Boom. Fascinated by these drinks and all the fears surrounding their use, I’ve applied my education (and basically all my free time) toward understanding the science behind energy drinks and their ingredients. In 2003, energy drinks contained synthetic caffeine as well as caffeine extracts from guarana and yerba mate. While synthetic caffeine was often criticized for being synthetic, guarana and yerba mate were often criticized for being “dangerous stimulants”. Then along came green coffee bean extract and coffeeberry/coffee fruit. As a caffeine consumer, you may be wondering, what is it about green coffee beans and coffeeberry that make it special? I encourage you to geek out with me over these game-changing energy drink ingredients.

Food Waste and a Master’s Thesis dream – GreenEyedGuide on ScienceMeetsFood

“This excerpt comes from the master’s thesis of a food scientist from UC Davis. That food scientist was me, Danielle Robertson, M.S. In my research, polyphenol procyanidin extracts were used, unsuccessfully, to prevent enzymatic browning in bananas. Seven years after that thesis was published, a company named Apeel Sciences has succeeded in creating an effective natural shelf-life extender entirely out of food waste. They succeeded where I did not, which is why I find this product so compelling.”

    Energy Drink of the Month – Oct 2016 : Bing Crisp

    Winter is coming. Do you need a little help keeping your energy up as the day winds down? How about a caffeinated beverage that doesn’t have the same stereotypical cocktail as the typical energy drink? How about something you can feel good about drinking – something with a little pizazz, or dare I say a little BING…

    The Energy Drink of the Month for October 2016 is Bing Crisp.

    It has apple and cherry juice, but there is also Bing original (cherry) and Bing Black (blackberry). The green one is my favorite (shocker), but your taste preference may vary.

    Between the three flavors shown and mentioned above, the WHO, WHAT, and WHEN is consistent, but I will refer to the ingredients of Bing Crisp specifically.

    img_20161013_2312031

    Who is this for? Target Audience

    Bing Crisp contains 100 milligrams of caffeine per serving / per 12 ounce can. This is about the caffeine content of a tall Starbucks Pumpkin Spice Latte, or an 8 ounce Red Bull. Unlike the PSL, Bing Crisp only has 8 grams of sugar – which is nice and low. Ingredients include cane sugar and sucralose, but there are no other sweeteners. Of course, apple juice does contribute its own sweetness, though.

    There are no artificial colors, nor artificial flavors, and the preservatives used include consumer-friendly, CSPI-approved potassium sorbate. The Center for Science in the Public Interest has been accused before of fear-mongering and cherry-picking scientific studies, so if THEY say potassium sorbate is okay, that’s a great sign. (We’ve talked about potassium sorbate before during the Panera KNOW-No Project)

    What is in it? Ingredients and Function

    This drink contains caffeine and an insignificant amount of ginseng (see PS at the end). Unlike typical energy drinks Bing Crisp also has beta glucan, grape skin extract (as resveratrol), and cherry juice. SPOILER ALERT: The amounts aren’t enough to really change your life, but enough to make this a better choice than other energy drinks.

    Beta glucan from oat fiber has been proven to reduce cholesterol and to reduce the risk of heart disease. To see this health benefit, you’d have to consume 3,000 milligrams of beta glucan a day, and Bing Crisp only contains 10 milligrams.

    “Because oat beta glucan is a soluble form of fibre it dissolves inside the digestive tract where it forms a thick gel – a bit like wallpaper paste. This gel is able to bind to excess cholesterol and cholesterol like substances within the gut and help to prevent these from being absorbed into the body. The gel and the cholesterol is then excreted as part of the body’s waste.”  – Health UK Fact Sheet – Beta Glucan

    Grape Skin Extract and… STORY TIME

    Have you ever thought about what happens to grape skins during wine making? The total tonnage of grape skin waste generated might make you sad. When I was in grad school, my thesis project was to prove you could use those wasted grape skins to get antioxidants which you could then use to prevent fruit from turning brown.

    YOU’D SAVE FOOD WASTE AT BOTH ENDS!

    Sadly, I never got the antioxidant extraction quite right (it’s hard to prove that a food isn’t turning brown from spoilage if you’re using a brownish-purplish coating to preserve it but that’s a story for another day). Bing DOES use grape seed extract, but only for coloring purposes and not in amounts large enough to mean anything in terms of antioxidant potential.

    Cherry juice has some interesting real-world research behind it. Cherry juice has been associated with reduced gout symptoms, improved arthritis, and boosted immune support. The research that interests me most involves running. Have you ever gone for a run and felt your throat get sore and dry afterward?

    tumblr_mqk2hlpnyq1s75dd1o1_500

    Prolonged and exhaustive exercise can cause upper respiratory tract symptoms – in other words, all that heavy breathing of polluted air with your mouth open can irritate your throat! Cherries have been shown to reduce that irritation because of the kinds of antioxidants they contain. [Reference – JISSN article]

    If you’re the kind of person that only runs because you have to, the cherry juice in Bing might help your post-run dry mouth. However, if you’re a legitimate runner, you probably need legitimate, straight cherry juice.

    When to take it? 5 Levels of Fatigue

    anigif_enhanced-buzz-2799-1399905452-4_preview

    During grad school, when I was doing research on energy drinks and their ingredients, I developed the 5 Levels of Fatigue. This system is designed to match the type and potency of caffeinated beverage with one’s true level of fatigue. In short, if you always reach for the strong stuff when you’re bored (not tired), it won’t work when you really truly need it.

    According to the 5 Levels of Fatigue, this product, with its 100 mg caffeine per serving, is Fatigue Level 2. Fatigue Level 1 is when you’re only tired because you’re dehydrated. Level 2 means you’re tired enough to need real caffeine, but not so tired that you need something with a big kick. Note – Different Bing flavors may have more caffeine, for example, Bing (cherry) and Bing Black (blackberry) have about 120 milligrams of caffeine, while Bing Crisp (reviewed here) and Bing Raz (not shown) have 100 milligrams caffeine.

    Bottom Line

    Bing has some interesting ingredients that make this a healthier option than the more stereotypical energy drinks. If you’re someone that has to have caffeine every single day, you can feel good that the grape extract, beta glucan, and cherry juice are contributing to your health through a long-term, additive effect.

    Energy Drink of the Month – June 2016: WTRMLN WTR

    What’s going on? Why is WTRMLN WTR on an energy drink blog? Because dehydration causes fatigue, and the solution (pun intended) for Level 1 of the Five Levels of Fatigue is water. With summer in full swing, it’s the perfect time to review the ingredients, hydration power, and food science behind this watermelon hydration drink.

    The Energy Drink of the Month for June 2016 is WTRMLN WTR.

    GreenEyedGuide.com Energy Drink of the Month for June 2016 is WTRMLN WTR.
    GreenEyedGuide.com Energy Drink of the Month for June 2016 is WTRMLN WTR.

    Yes, this is literally the water from a watermelon, not water that’s been enhanced with fruit juice extracts or add-ins. Food Waste is a growing concern among food scientists (and consumers!) so I was overjoyed when I learned that this product is made from watermelons that would otherwise be discarded.

    WTRMLN WTR Nutrition Facts and Ingredients – GreenEyedGuide Energy Drink of the Month June 2016

    This drink is a little bit sneaky with its serving size. One bottle is actually one AND A HALF servings, and the Fact Panel pretends you’re only going to drink two-thirds of the container (8 of 12 ounces). This is a pet peeve of mine, but the new FDA food labeling regulations should resolve this.

    One reason this serving size decision bothers me is that the label compares the sugar and electrolyte content of WTRMLN WTR, orange juice, and coconut juice. These comparisons are “per serving”, but that is not helpful because the serving size is arbitrary. If you Googled “what is one serving of fruit juice”, you’d find the American Heart Association explain that one serving of fruit is one whole medium-sized fruit or one-half cup (4 ounces!) of fruit juice. And yet one whole 12 oz bottle of orange juice can also be labeled one serving.

    With this inconsistency, it’s better to compare the nutrients per ounce than per serving.

    Hydration Power

    WTRMLN WTR label GreenEyedGuide Energy Drink of the Month June 2016
    WTRMLN WTR lays out the people and situations this product is suited for…

    The ideal hydration beverage has 6-8% carbohydrates, according to the research review article, “The effectiveness of commercially available sports drinks.” In the table above, Gatorade falls in that ideal range – shocker – but so does WTRMLN WTR. When are these hydration beverages most effective? According to this same research review article:

    • Consumption during short duration high-intensity exercise may enhance performance
    • Consumption during prolonged intermittent exercise can improve performance
    • Consumption during prolonged exercise (meaning 1-4 hours) may enhance performance

    Food Science – What is Citrulline?

    WTRMLN WTR What is Citrulline - GreenEyedGuide Energy Drink of the Month
    Did you notice the “bedroom” claim on the label? Citrulline has some pretty interesting use cases involving the Urea Cycle, Nitric Oxide Metabolism, and muscle fatigue!

    The more I read about citrulline, the more I wanted to learn about it. A “deep dive” on this ingredient is forthcoming later this month, but here are some key facts you should know.

    1. Citrulline is also known as watermelon extract.
    2. Citrulline gets its name from watermelon – watermelon’s Latin botanical name is Citrullus vulgaris.
    3. One average watermelon contains 2.1mg citrulline per gram
    4. In the sports supplement world, people take citrulline (as L-citrulline or citrulline malate) to increase the levels of amino acid arginine in the body
    5. The kidneys turn citrulline into arginine, which is supposed to delay muscular fatigue [Bodybuilding.com’s Complete 2016 Supplement Guide rates this ingredient/function claim as “Great: Inconclusive findings but anecdotal evidence is favorable and the ingredient is considered safe for use”

    Comparisons and Conclusions

    How does this drink hold up to plain old water? Well, it’s certainly tastier, and potentially more expensive. If you’re one of those people that have a hard time drinking enough water throughout the day, this product could be one way to drink more.

    How does this drink hold up to orange juice? Comparing ounce-per-ounce instead of tripping over serving sizes, WTRMLN WTR has fewer calories and fewer grams of sugar. It also has less Vitamin C.

    How does this drink hold up to other watermelon beverages we’ve reviewed at GreenEyedGuide? Well, WTRMLN WTR is not caffeinated, so if you’re one of those people who need help getting up for your 5 am workouts, WTRMLN WTR may not be the best pre-workout drink.

    My initials are DR but I’m not a doctor, so take my insight with a grain of salt and take all caffeinated beverages with a tall glass of water.
