Mr. Swift and Mr. Thrift: Book Excerpt of the Week

January 23, 2017September 7, 2019greeneyedguide

HOW QUICKLY you consume caffeine is JUST AS IMPORTANT as HOW MUCH caffeine you consume.

❎This is why I don’t like energy shots! If it’s more caffeine than you can handle, it’s too late because you’ve consumed the whole thing in one gulp.❎

Sipping your caffeine and even breaking the 1 can = 1 serving suggestion (treating 1 can = 4 servings) you can decrease the total amount of caffeine you consume in one day and ultimately teach your body to work just as well with slightly smaller doses.

Consider the Book Excerpt of the Week from PART TWO: Do They Work Energy – Synergy and the WHO, HOW, and WHEN

Mr. Thrift sips his caffeine throughout the day to make it last. Mr. Swift makes sure to drink every last drop of a 16 ounce can containing 160 mg caffeine on his way to work. By the end of his shift, he feels like he needs another can. With caffeine’s half-life of ~4 hours, there is still ~80 mg in Mr. Swift’s system. However, with his consumption habits, this won’t feel like enough.

Story Time

When I was in grad school I would drink a full bottle of water, then pour half my energy drink in that empty bottle and save it for the next day. The carbonated energy drinks would lose all the carbonation overnight, but I didn’t care. The caffeine still worked. To this day, I rarely finish a whole energy drink in one day. Those days that I do, it’s a long drawn out consumption, to ensure I don’t consume more caffeine than I absolutely need.

Monday Punday meets Caffeine Safety Limits – Book Excerpt of the Week

December 19, 2016September 7, 2019greeneyedguide

Pretend you’re on a on vacation and you’re given $400 a day, every day, to cover your expenses. Would you spend that all at once or try to make it last the whole day? Now pretend that money allowance is actually your caffeine allowance, which brings us to our excerpt of the week:

The Background

Consuming up to 400 milligrams of caffeine per day is considered safe for the healthy adult population. This limit was determined by the Bureau of Chemical Safety, Food Directorate of Health Canada. The FDA uses this limit because it’s based on a comprehensive review of published studies on the effects of caffeine on human health.

Essentially the authors of this review searched all published studies on human health and caffeine, then determined the overall consensus among the studies.

The consensus was consuming 400 milligrams of caffeine per day doesn’t pose a threat to the heart, the bones, or male fertility, and doesn’t cause general toxicity or increased incidents of cancer. Consuming caffeine safely means not exceeding this 400 milligrams per day limit.
The Lesson

Before consuming an energy drink, look at the number of milligrams of caffeine per serving and the number of servings per container. Careful not to blow your whole caffeine allowance in one shot.

What do energy drinks, aspirin, and multivitamins have in common? Book Excerpt of the Week

December 12, 2016September 8, 2019greeneyedguide

You wouldn’t eat 5 multivitamins or take 10 aspirin a day because that could make you sick. How frequently you consume an energy drink is just as important to your safety. There are many energy drinks* that are not bad for your health nor dangerous if consumed in moderation.

[*And then there are caffeinated supplements, including powder pre-workout supplements and liquid drinks like REDLINE that have so much caffeine per serving they are dangerous/too caffeinated even when consumed as directed]

This Book Excerpt of the Week comes from PART ONE: ABCs of Caffeine Safety, C= Consumption Specifics.

How much caffeine can I have a day? Book Excerpt of the Week

November 21, 2016September 8, 2019greeneyedguide

This Book Excerpt of the Week is from PART ONE: ABCs of Caffeine Safety – B=Biological Sensitivity. Did you know a healthy adult can consume up to 400 milligrams of caffeine per day? This magic number is the conclusion of a massive study on caffeine intake and what amounts trigger side effects and health problems.

capture-mon — PS – I also post the Book Excerpt of the Week every Monday morning on my Instagram page! Find me ‘greeneyedguide’

Obeying this this limit is SO IMPORTANT because it means the caffeine should not cause any side effects of bone health and calcium balance, heart health, changes in behavior, incidences of cancer, or male fertility. Going above this magic limit is, well, pushing it. It goes without saying that your personal limits may vary depending on your own sensitivity. Also, I should not have to point this out, but it would be unwise to consume your whole day’s worth of caffeine in one sitting.

As I mentioned with the Book Except of the Week from last week (Caffeine and Panic Attacks), THIS IS WHY IT DRIVES ME CRAZY when people talk about energy drinks WITHOUT DISCLOSING THE AMOUNT OF CAFFEINE. ~~Energy drinks~~ caffeinated beverages and supplements are definitely not for everyone but it’s important to include these details so people can make informed choices about which products work and don’t work for them.

Help me share my story– An energy drink is like your favorite song: what works for YOU might not work for me, and what works for you on a Monday morning may not be your go-to for a Friday night. As the GreenEyedGuide, I use food science to teach people how to calculate what they need and when, whether it’s water, a nap, or some healthy beverage in between.

Energy Drinks and Hepatitis – What You Should Know

November 3, 2016September 8, 2019greeneyedguide

You’ve probably seen this story on CNN and other outlets. There are some additional details I want to add based on the 10 years I put into researching energy drinks and their ingredients. In the CNN article, I do understand why it’s mentioned this man had excessive folate and vitamin B12 levels, and yet the blame for the liver problems went not to B12 nor folate, but exclusively to niacin. Excessive folate masks B12 deficiency; excessive B12 doesn’t have documented symptoms, and excessive niacin HAS in fact caused liver damage. Liver damage may occur at 1.5 GRAMS (1500 mg). However, the man in this story reportedly only consumed 5 cans with 40 mg niacin each, or 200 mg niacin total. That doesn’t seem like enough to hit toxicity levels. Another thing to consider is how Niacin Flush occurs at 30 mg; if someone was consuming an excess of niacin, usually they’d feel it.

I’m always aggravated when “energy drinks” are treated all the same. Have you see the “energy drinks in disguise” I’ve been talking about here on this blog? Do you even realize how different the New Age of energy drinks more closely resembles “functional beverages” than the energy drink stereotype. But I get it — some stereotypes are just too persistent.

In that case, what aggravates me most of all in this particular story is how the caffeine content is curiously missing from the details collected or any of the blame assigned/implicated in this piece. It’s aggrivating to me when a news story casually implies energy drinks have caused a medical condition, and yet the details of that energy drink are missing. What OTHER ingredients were in there? Any EGCG? How much caffeine? How much sugar?

♦

This is important because there are some really critical details missing from the news stories, and yet they’re not wrong. It’s TRUE that TOO MUCH Niacin can hurt your liver. But HOW MUCH is TOO MUCH? (1.5 GRAMS) That’s what is missing from these news stories. That’s what I want to share with all of you. There’s no need for panic, but there IS a need to be more informed.
