Optimizing Your Caffeine Intake With an App

samzenpus posted more than 2 years ago | from the take-another-shot dept.

Software 134

MrSeb writes "Two doctors at Penn State University have developed Caffeine Zone, a free iOS app that tells you the perfect time to take a coffee break to maintain an optimal amount of caffeine in your blood — and, perhaps more importantly, it also tells you when to stop drinking tea and coffee, so that caffeine doesn't interrupt your sleep. By reading through lots of peer-reviewed studies, doctors Frank E. Ritter and Kuo-Chuan Yeh found that a caffeine level of between 200 and 400mg in your bloodstream provides optimal mental alertness, and that you should be below 100mg when you try to sleep. Caffeine Zone plots your caffeination level after you consume caffeine, and warns you if that big afternoon coffee will keep you up at night. It also lets you change the 'optimal' and 'sleep' values if you're particularly resistant or weak to caffeine."

The good thing about antioxidants is that they reduce the free radicals in your system, which have been hypothesized to be linked to cellular damage. Although, after almost twenty years of research, there is still no clear evidence of this.

The bad thing about antioxidants is that they reduce the free radicals in your system, which have been repeatedly shown to be critical for fighting off bacterial disease.

Re:Caffeine (0)

If that's the case then you obviously have a drug addiction and might want to consider getting it under control. Your body gets quickly accustomed to the caffeine, so you'll need more and more just to get to a "normal" level. If you can't stay awake without it then using your holidays for a detox might be one of the best things you've done for yourself in a long time. Trust me, I've been there!

I've had caffeine problems in the past and am now rolling back to Green Tea. Just enough of a prod. The problem with Coffee is it's a big hit and the subsequent sips provide a declining return on alertness, but an increase in fidgeting, anxiety, etc. A more modest dose from tea and I'm less likely to become accustomed to high levels of caffeine which only serve to keep me at a body-acclimated "normal".

ayep

I don't drink coffee, so on the odd occasion that I grab a small foam cup at work I find it makes me edgy, and it actually makes me jittery ... breaking concentration. I sometimes drink tea, but tea is a PITA when no one else drinks it, and unlike coffee which I like best black, I cant stand tea without a little sugar in it, which early in the morning gives me heartburn.

Re:Simpler method (1)

vikisonline (1917814) | more than 2 years ago | (#39071509)

That should depend on your type of tea. Some tea's like the lemon ones I can't have without sugar or its too bitter. Other ones like chai, I could not imagine drinking it with sugar ( but that depends on the brand too. The tim hortons ones are good with 2 bags and let it soak till its dark ).

But just experiment around. I'm sure you'll find a tea you like without any additives.

Coffee is great in small doses. The huge mugs that Americans favor and the super mega vente that most people buy at the coffee shop is way overkill. I found that coffee was making me edgy until a friend from Europe gave me a set of very nice small cups, maybe six ounces. If I have one of those in the morning, sitting on my back porch with the wife, it gets me off to a nice running start and doesn't keep me awake at night.

After that, it's just herb tea or slivovitza. Once in a while a Yoohoo and Jagermeister over crushed ice, because the elk blood is good for my gout.

This is the case - your first hit of coffee has more impact than any more you drink all day - rate of declining return - as your body acclimates to it and your cognitive self also makes subtle adjustments. Star*ucks is far too strong and I only get on gift cards when traveling, in the smallest cup size - even that will last more than one day.

Keep in mind that Europeans drink stronger coffee than Americans.
The recommended dosage for "ideal" coffee is 65-75 grams per liter in the US, and 75-90 grams per liter in Northern Europe.
Add that most Americans prefer their coffee weaker than recommended[*] - one scoop per cup is common, which translates to 4 scoops per quart, whereas in e.g. Norway, the recommendation is seven scoops per liter, plus "one for the kettle", or about 8 scoops per quart.

So chances are that your European friends get as much if not more caffeine from one small cup of coffee than what you'd get from a large 20 oz Starbucks.

[*] In part, I believe, because Americans drink more central and South American coffee high in organic acids, while Europeans drink more African coffee, higher in inorganic acids. With American roasts also being lighter and thus more acidic, it helps explain why the coffee is brewed weaker - few people would like to drink sour coffee. In comparison, a typical European coffee would taste less acidic but more bitter.

Believe me, you just can't group Europeans like that. I'm Italian. I simply cannot drink what they call coffee in any northern country. Spaniards, Greeks and Turkish have interesting ways of preparing coffee too. Northern countries are very similar to Americans in their coffee habits.

65 grams per litre will kill you. The LD50 is about 20 grams. OTOH, I'm drinking a Relentless here containing 160mg, so 90mg per litre sounds like some weak-ass coffee if you're only drinking 1/3 litre at a time.

I appreciate what they're trying to do, but really, each person has their own caffeine profile and has to find where it works and where it doesn't.

Very true. Whilst they can probably accurately model the caffeine absorption into the bloodstream, there are two factors that the app cannot know.

  1. Amount of caffeine per coffee. Whilst this is predictable with instant coffee, different coffee beans differ in the amount of caffeine in them. Percolators are not bad but if you drink espresso based drinks then the amount of caffeine per shot can vary by a factor of 8 (fineness of the grind, tamping, how the shot is pulled etc).
  2. Each person metabolises caffeine at a different rate. Young people and teenagers can take up to 72 hours to metabolise caffeine whereas adults can do it in anywhere between (about) 2-3 hours and 10 hours. This is why some people can't get a decent night's sleep if they have a coffee after about lunchtime, whereas some are fine.

I like the idea of this app (for kicks) but without those two factors it's not going to be very accurate

rebelwarlock (1319465) | more than 2 years ago | (#39070049)

Does it come with testing hardware so that it can determine precisely how strong your coffee is, and thus more accurately calculate your intake? Does it come with measuring tools to know how much you're pouring into your mug? How about accountability for the additional influence of sugar? What about people who have become desensitized to caffeine? There are too many factors they haven't considered, not least of which being how they're going to convince me to jam a needle in my liver so they can determine how well it's working.

Does it allow for those of us who needs coffee to sleep?

I grew up in a culture where 7 cups a day was average, which, when accounting for those who don't drink coffee, meant 10-12 cups a day for coffee drinkers. Often including a bedside mug. Then I moved to the US, where people have a belief that coffee can make them unable to sleep, and that's when drinking making-love-in-a-canoe coffee. I think it's at least partially psychosomatic - people get restless from coffee because they expect to, and because it's a pick-me-up in the morning, they believe it's also going to wake them up if drunk at night.
Sure, caffeine is a stimulant, but American coffee has extremely low doses. The theobromine in a cup or bar of chocolate is more of a stimulant (never mind the sugar), and they don't seem to have the same belief about chocolate keeping them awake.

Sure, I have probably built up a tolerance, but I didn't have any problem with coffee keeping me awake when I started drinking it either. About a pot of strong coffee a day during summer at age 14, and I slept like a log. Nobody told me I would have problems sleeping, so I didn't.

Re:Too many missing pieces (1)

nprz (1210658) | more than 2 years ago | (#39071379)

I didn't drink coffee until I finished college and started working. From middle school up until that time, I drank soda. I had my part-time job at a place giving out free soda, so I probably drank a gallon a day.
Now that I'm on coffee, I have at least 6 cups a day to feel normal. Drinking it before going to sleep has no affect.

Worrying about work and what-not would keep me awake, so I usually try to note down any brilliant ideas when lying in bed and that usually helps.

I used to think the soda kept me up at night, but it really is just the computer (and its addiction).

There are a couple of other tests they don't mention, but it's pretty well established that sugar doesn't make kids hyper. The excitement from having something sweet and tasty might do that, but even that seem to be pretty psychosomatic on the parents' part.

Re:Too many missing pieces (1)

voidphoenix (710468) | more than 2 years ago | (#39071517)

Except actual experience with kids will demonstrate otherwise. My opinion of the matter is based on observing my niece and nephew, both when they and their parents were living apart from me and after they moved in with us. We had no expectations, neither I nor my siblings had sugar/hyperactivity problems when we were kids. But my sister's kids both react to sugar, albeit with noticeably different tolerances. The boy (7) is affected by lower doses of sugar than the girl (6), but both will exhibit startlingly different patterns of activity after a big jolt of sugar. My nephew apparently feels it, and will often start jogging back and forth to bleed off the excess energy, because he just can't sit still when it happens. Here's the kicker: the boy is so sensitive that he gets hyperactive if he has a big rice meal (rice is a staple in many parts of Asia). Please note that non-fiber carbohydrates (sugar and starch) you ingest break down and are absorbed more or less directly into blood sugar.

The bottom line is that different people will have different responses to different chemicals, and sugar can and does have an effect. On the plus side, these two kids are pretty smart and now police their own sugar intake. They take smaller servings of sweets and avoid them from late afternoon onward.

Yes, you're absolutely right - there is no possibility that this app can/should be taken seriously. That it's being promoted as developed by 2 doctors is a more worrying issue (or would be, if I cared), as the more credulous members of society, with no self-control, will make the basic error of believing what it tells them.

In practice it's just a bit of silliness for people who feel the need to justify the amount of coffee they drink. Hopefully the next version will link coffee intake with biorhythms - so we can see exactly how much credibility to give it.

Re:Too many missing pieces (1)

Hadlock (143607) | more than 2 years ago | (#39071789)

A standard cup of coffee/tea is about 100-110mg. Being a crop it can vary 10-15% in either direction from lot to lot, even the same brand/flavor. BMI has loopholes too (like body builders), but for many young people just entering the workplace, that giant pot of free coffee is enticing and this could really help a lot of people become more aware of how strong drugs like caffeine effect your body. Sure, you'd be better off with blood tests and a full suite of diagnostics, but like the food pyramid, I don't think many people disagree that refined sugars should be consumed the least.

Re:Too many missing pieces (0)

Good point!
I live now in The Netherlands and the coffee I drink at work is considerably weaker than what I was used to back in Portugal, to the point of drinking quadruple, both in frequency and amount (2 times more often and double expressos) than what I used to when I was in Portugal. This isn't something of getting used to as I do get a Portuguese brand for home and then I get the same jolt as I used to.
In the end it took me a bit to get used to this and have a complete different routine.
By the way, we had a few different brands so far at work and all of them seemed quite week and similar in terms of amount of cafeine in them.

It tastes so good, that's why i'm addicted. I'm constantly on and off coffee. I hate the caffeine but love the taste. I'm on decaf now but it tastes bad. What I don't get is people who need to add cream & sugar. Why not just drink soda at that point?

Don't mean to troll here but maybe decaf doesn't taste so good because as you swig, the caffeines not there to light the 'taste' up?

I wouldn't think so - caffeine by itself has a rather bitter taste. Energy drinks add tons of other crap as much for marketing as to work around it.

No, it's because decaf inherently tastes bad.

Basically, when making coffee, the idea is to extract some chemicals from the coffee beans using hot water. Those chemicals are volatile organic compounds, for the most part. If you leave a coffee bean exposed to the air for a while (or a ground coffee bean exposed to the air for an hour), most of those chemicals will evaporate. The resulting coffee would taste terrible - much of what makes it taste like coffee would have evaporated.

Something similar happens with decaf. You have to try to extract the caffeine, without extracting the other compounds that make it taste like coffee. That's really difficult, because any process you might use to extract caffeine will extract other chemicals as well. Much of what makes it taste like coffee would be lost - you can take some decent coffee, decaffeinate it, and it'll end up tasting bad.

You can work around that by using much higher quality coffee beans - you take coffee that would taste really good, and it'd end up tasting OK. The problem with that is economics.

It turns out that people aren't willing to pay any extra for decaf compared to regular coffee. Since the decaffeination process itself adds cost, the only way to sell decaf for the same price as regular coffee is to use lower quality (cheaper) coffee beans. So now you're taking bad coffee, and making it worse. Aside from which, if you're producing coffee beans, why would you take the best you have and ruin it, when you could sell it as-is for a much higher price?

It is possible to have decaf coffee that doesn't taste like crap. It's just difficult.

This is the exact reason I've heard from many different sources. If you were willing to pay 50% extra for decaf, then you could have primo beans, no caffeine and good-tasting coffee. Most people won't pay the extra, thus most decaf tastes like crap.

It's actually in the roasting and processes used to make decaf. For one thing, it's almost universally roasted so dark that it's basically burnt, and becomes extremely bitter. The lighter and medium roasts that have the more mellow flavours actually have the highest caffeine content.

A big difference is that caffeine is naturally occurring in lots of plants and not a major health negative especially as far as stimulants go. On the other hand only my kids believe that there is a McNugget tree in the wild despite my best efforts to avoid that shit.

Honestly, why do people addict themselves to this crap? Stop eating McCrappers all the time, get some exercise and you might be surprised how much energy you have without caffeine. You'll feel a lot better, too, not being buzzed and strung out all the time.

You sound really irritated and snappish - a cup of coffee might help soothe your nerves.

I was a twice daily autodrip coffee drinker, cup in the morning, cup or 2 in the afternoon when one tends to the the dowsies at a dull day job. 2 years ago I made an effort to stop drinking coffee. I didn't think myself a heavy coffee drinker, but it was that afternoon problem of getting drowsy... it was getting worse and I'd need more and stronger coffee. I was successful without much effort. I quit, and ate fruit instead, and the drowsy afternoon problem went away; I found myself alert in the afternoons. A few months later, after having no coffee whatsoever, I was given a coffee gift card... and within a few visits became addicted to esspresso... and since have spent a depressing amount on coffee. And I have tried to quit... and its really difficult. I need 6 or so shots a day just to hold it together.

Go into coffee induced mild coma at 2pm

After just 7 cups? Hardly. That's about the average coffee consumption in Scandinavian countries, when the average includes those who don't drink coffee at all.

It's just coffee - it's not like you're downing wellbutrin or ritalin.

It's not as bad a drug as you might think - disregard "studies" done or sponsored by Loma Linda (adventists) or BYU (mormons) who have a religious agenda against coffee, and you'll find little to indicate that it's all that bad for you in moderation.

I've never drank coffee on a regular basis. I've drank maybe under 100 cups of coffee total in my entire life. I've never had a problem with drowsiness or alertness. I get a good amount of sleep at night and decent exercise. This is all you need.

I would argue the majority of people drink coffee and tea for the taste and caffeine is just part of the deal or a perk for some. There are just so many better ways to get jacked-up on caffeine if that is the sole goal. I too don't drink coffee, but love a nice Earl Grey every now and then.

Caffeine is a drug that's sadly overused to the max. Surely, the best thing must be to avoid taking caffeine at all? It's really mind boggling how our culture nurtures it to the point that they now talk about "optimum caffeine level" in your blood. Wow, just..wow.

Reportedly commercial cigarettes have sugar added to them [[citation needed]] which interacts with some of the other additives + nicotine in the tabacco to improve it's stimulating effects.
 
In Peru they make a really tasty margarita-tasting thing made with ice, vodka and coca leaves (the same species they extract Cocaine and Novocaine from - the leaves are legal and widely available in most of South America) which leaves you up all night and full of energy, which is good because the bars in the touristy areas never fully close.

I drank my last one then and haven't touched it since. I know some people it's ok for, however like most drugs they affect people in different ways.

Some drinkers get merry, happy and have a good time, others want to beat people up.
Coffee makes me an addict, takes my energy away, wrecks my sleeping patterns and is generally not a good thing to go near.

I have weak jasmine tea now, awesome drink, much better - can sip at it all day from a thermos as if I'm in a Vietnamese resteraunt.

Only way to "optimise" your coffee intake? (1)

zedrdave (1978512) | more than 2 years ago | (#39071957)

Don't drink it regularly... (note that I did not say "don't drink it EVER... it will kill ya... coffee's bad" etc. etc.)

It's not witchcraft, people: coffee is a drug (a reasonably mild one at that), like many drugs your body builds a tolerance to it real fast. The more you drink it, the less effective it is, up until the point where your hourly cup barely keeps you at baseline wakefulness (kinda like crack, really, but much cheaper). I could quote you a gazilion studies on that, but I'm pretty sure you already have that one coworker whose 12 cups/day diet does not make particularly on edge (but who gets the shake if they go without caffeine for a couple days).

Restrain yourself, only drink coffee (in small dosage) when you particularly need the alertness or wakefulness, and you will be making optimal use of it (at minimal cost on your kidneys).

And if 24/7 "optimal mental alertness" is what you are really after, then why do half-measure: just skip to amphetamines directly.
