Is there Caffeine in Apples?

caffeine-in-apples
There is somewhat popular health advice being passed around that states eating an apple wakes you up as well as a cup of coffee.

I’m not even sure where this statement originally came from, but some have come to believe that apples must contain caffeine. Let’s have a look at the nutrition data of an apple and see what ‘an apple a day’ is actually packing.

Nutrition of an Apple

Serving size182 grams (1 medium apple)
Calories95
Sugar19
Protein0.5mg
Vitamin C8.4mg
Vitamin A98.3 IU
Folate5.5mcg
Choline6.2mcg
Calcium10.9mg
Phosphorus20mg
Potassium195mg
Caffeine0mg

Apples also contain very small traces of other vitamins and minerals.

No Caffeine in Apples

An apple will wake a person up somewhat, but it’s not because of caffeine. The high sugar content of an apple is what does the trick.

Fructose is digested quickly which raises blood sugar levels and gives the body, more or less, a sugar rush.

In fact, one medium apple has about the same sugar content as drinking half of a 12oz Coke.

So even though apples don’t wake you up with a jolt of caffeine, they are a healthy way to get a sugar rush.

    Well, buy an apple and some caffeine testing strips and test yourself silly… It will show no caffeine….

    We do. It’s called the coffee bean.

    It keeps you awake because of the way your body digests the apple / apple juice. I’ve been using it for years on night shifts. You are not alert buzzing you are awake though.

    Sugar rush is a myth. Kids drink cola with caffeine, thus the rush. Mothers who swear their kid gets sugar rush cannot find a way to eliminate the caffeine from the kid’s diet. Imagine drinking vodka and eating a banana, and then blaming the banana for making you drunk. That’s how moms reason about caffeine and sugar.

    It is also possible for kids to get extremely excited about eating sweets. They could get a texting rush as well.

    Rob, do you also drink coffee?

    Hyperactivity and sugar rush are not the same thing. I taught middle school for 12 years and can attest that sugar rush is indeed a real thing. Even personally, If I have something sweet shortly before bedtime, I have difficulty falling asleep.

    You are playing with words. When a mother says her kids are “bouncing off the walls” after eating or drinking something sweet, that is BEHAVIOR. It seems your personal anecdote is more scientific to you than any scientific clinical studies, so I am wasting my time explaining it to you. Even so, if you do have the ability to open your mind, read this (that I already mentioned in my online post): http://en.wikipedia.org/wiki/Sugar_high#Human_body_and_health (Scroll down to “Nutrition, food, and drink”) It says “Double-blind trials have shown no difference in behavior between children given sugar-full or sugar-free diets, even in studies specifically looking at children with attention-deficit/hyperactivity disorder or those considered sensitive to sugar.” Mothers (and probably you as well) do not get out any stethoscope to check heart rate or blood pressure for their kids. They observe BEHAVIOR and call it “sugar rush”. The clinical studies cannot agree with this. The mothers likely would see a “rush” if the kids were told they would be going to Chucky Cheese even if no sugar preceded the announcement.
    It doesn’t matter if you classify it “rush” or “hyper”. You are too old to be hyperactive. Your rush / sleeplessness / whatever you want to call it is not caused by sugar. Did you drink a soft drink, tea, or coffee before bed? If I eat a slice of bacon before bedtime, I may have sleeplessness. It isn’t caused by nitrates. It might be caused by a bill that came in the mail or news that my uncle has cancer. A hundred things could cause sleeplessness, so don’t try to blame sugar.

    Sugar in Apple’s have a low glycemic index. Which means it will give more sustained energy then a cup of coffee

  • Maxwell

    A sugar rush is a real thing, All food breaks down into sugars within the body for use as energy, when you eat or drink high sugar content foods the sugar does not need to be broken down first like other carbs and immediately enters the blood stream in large quantities, thus high energy levels.

  • Jim

    Mainly, what you’ve demonstrated through these comments is just one thing: A lack of understanding of the role carbohydrates play in the body. Not mention a lack of understanding of what carbohydrates even are, let alone the differing types.
