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:
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.

Why is it a 15 year old in the US can only have 100 milligrams of caffeine a day, while a 15 year old in Canada can have 400 milligrams? For the book excerpt of the week, we consider the difference in caffeine limit recommendations from US and Canada.
You may need these guidelines if the US presidential race has prompted you to consider moving to Canada. Regardless, it’s interesting to consider Canada’s approach to caffeine safety for kids.

March is Caffeine Awareness Month, and what better way to celebrate than to revisit some of the most popular caffeine-related GreenEyedGuide posts! Remember that rebuttal to BroBible’s energy drink article or the open letter to Time magazine? How about the three tips for parents or the two Year-In-Review lists of all the “Energy Drink of the Month” winners? Do you remember what happens when energy drinks dress up like workout supplements?

BroBible may be have expert insights on some matters, but their article on energy drinks proves biology and food science isn’t in their wheelhouse. Here’s the point-counterpoint to all the misleading statements in their article.
As a food scientist who’s studied energy drinks for over 10 years, Ms Sifferlin’s article came across as yet another “all energy drinks are lethal” story. While the article was missing many crucial facts, there were three points in particular that should be part of the conversation.
This presentation covers the effects of caffeine when it’s consumed before, during, or after a workout. We also review how the Five Levels of Fatigue helps people determine which caffeine products (if any) are right for them.
Energy drinks are in the news again, and this time the story is the reported increase in emergency room visits attributed to energy drinks. Are these stats more indicative of consumer misuse or that energy drinks are inherently more dangerous than other caffeinated beverages? Some clues to consider.
As always, my goal is to educate and inform, to provide an alternate perspective to help people look past confusing scientific jargon and learn the tools to making the best choices for their lifestyle. Caffeine is not always the answer but to find the right answers we must ask the right questions.
How concerned do parents need to be about the use of energy drinks in kids and teens? In the Green-Eyed Guide guest blog on The Scientific Parent, we review the three major details often left out of these conversations on caffeine, and how these details can dramatically boost our efforts to keep ourselves and our kids healthy and safe.
A study published in January 2014 involving over 40,000 people defines beverage caffeine intakes in the US, revealing the amounts of caffeine consumed and from what source per age group. As your Green-Eyed Guide, I’m going to explain what it all means.
What can 42,000 people tell us about the caffeine habits of the US population? Plenty, if you look at the right details. Understanding this information is critical to any conversation about caffeine safety.
With new caffeinated foods popping up, the FDA is getting more pressure to reevaluate the safety of caffeine, particularly for adolescents. We evaluate the impact of caffeinated gum and why CANADA has the best caffeine regulations.
ENERGY DRINK OF THE MONTH YEAR IN REVIEW (YEAR1 AND YEAR 2)
While I am all for food science innovation, I am extremely cautious to with anything that makes it harder for one to keep track of how much caffeine they’ve consumed. Yes, I know there’s an app for that. But in a world that both loves coffee and loves to talk about the “dangers of energy drinks”, coffee flour warrants some concern.
An article in FWx discusses new caffeinated flour which can provide 100 mg (aka more than an 8 oz Red Bull) per 4 g flour. The innovation implications are enormous, and wonderful — a product developer’s dream come true! For caffeine and carb lovers, this innovation is the greatest thing since sliced bread! HOWEVER, the application can easily cause problems for those who do love all things caffeine (and/or carbs).
What if someone uses the new caffeinated peanut butter on their caffeinated toast? What if they then wash it down with a large cup of coffee or tea (caffeine amounts vary) or even just something made with green tea extract (such as a V8 V-fusion: 80mg caffeine from green tea extract)?
The European Food Safety Authority confirmed that up to 200 mg caffeine can be consumed per sitting, and 400 mg caffeine is the maximum daily dosage that is safe for healthy adults (anyone under 18 should stick to 100 mg, unless you’re Canadian then it’s just anyone under 14). How easy will it be for one too many (caffeinated) bagels or bear-claws to put someone past the point of safe caffeine consumption?
This innovation should be celebrated, with caution. Let us take this opportunity to revisit caffeine safety and how energy drinks aren’t the only “danger” for over-consumption.
Let’s play a game. If I say “energy drink,” what comes to mind? Extreme sports athletes? Teenagers in the hospital? Green tea? News outlets often portray energy drinks as dangerous concoctions of sugar and caffeine but this isn’t the whole picture. While some energy drinks are loaded with sugar and caffeine, the truth is there were over 200 different energy drink brands in the US as of 2009, and some of those are more like green tea than the sugary caffeine-loaded product portrayed. Since many popular energy drink ingredients are also popular in fitness/health supplements, it’s time to consider the energy drink facts no one is telling you.
