When it comes to the best fruits for you, apples seem to be the gold standard. I mean you’ve heard it before—an apple a day…yeah yeah, you know the rest. But how many kilojoules, exactly, are in an apple—and is that staple your mom packed in your school lunch really that great for you?
Well, it turns out apples really do live up to the hype. Can you hear your mom saying, “I told you so?” When it comes to healthy snacks, it doesn’t get much better than apples. They’re loaded with vitamins, have a pretty long shelf life compared to other produce and are super easy to pop into your bag on the go.
“Apples are the second most consumed fruit, behind bananas, for a reason,” says Alex Caspero, registered dietitian and author at Delish Knowledge. “They are generally inexpensive, portable, healthy and delicious.”
Plus, since apples come in a ton of different varieties—way beyond the Red Delicious and Granny Smith kinds you ate as a kid—you’ll probably find something your taste buds will totally love. The flavour profiles of apples range from tart and crisp, to sweet with a little crunch, to tangy and then some.

Whichever you’re preference, though, it’s typically healthiest to eat your apples in their purest form—as a fruit, says registered dietitian Erin Palinski-Wade. “Eating raw apples is a great way to take advantage of their full nutrient benefits and fibre. Although eating apples in dessert form, such as apple pie, can still provide nutritional value, it also incorporates a large amount of added sugar which can be damaging to health.” That doesn’t mean you can’t have those apple turnovers you love, but it’s best to have them in moderation.
So before you set your next apple-picking date (at the farm or supermarket), here’s what you should know about the treasured fruit.
How Many Kilojoules In An Apple?
As far as kilojoules go, you’ll find 397 (that’s 95 calories) in a medium apple, according to the USDA. But the fruit has a lot of other things going on for you nutritionally, too. Here’s how a medium apple stacks up with the skin on:
If that sugar count makes you do a double take, consider this: The sugar you’d get in an apple is not the same as, say, the 21 grams of sugar you’d get in a Kit Kat bar, says Caspero.
“Fibre is nature’s way of controlling blood sugar levels, which is why it’s found in fruits and vegetables,” says Caspero. “Fibre helps to slow down digestion, which prevents blood sugar spikes like you would get from an equal amount of the sugar in candy.”
To regulate those blood sugar spikes even more, Kristin Kirkpatrick, RD, offers a sneaky—and delicious—strategy: “Provide what I call ‘competition for digestion’ by pairing your apple with a fat or protein. A perfect example is an apple with no-added-sugar peanut butter.” This clever pairing helps your body process the sugar slower to give you sustained energy and fuel. Bonus: The vitamin C in apples helps you better absorb the iron in nut butters, helping you get the most out of your snack.

Eating just one medium apple will earn you 14 percent of your daily value of vitamin A and 11 percent of your daily value of vitamin C (not shabby). Antioxidants (like vitamins C and A) in apples help prevent excessive free radical damage, says Caspero. Staving off these free radicals (a.k.a. unstable atoms in your body) can help reduce ageing and the risk of illness.
Apples come in a range of stunning hues and if you tend to gravitate toward the darker ones, you’re in for an antioxidant-rich treat, according to Kirkpatrick. Deep-pigmented peels on fruits like apples contain anthocyanins, a form of antioxidants that slow down oxidative stress and ward against disease. Keep in mind that you’ll only reap the majority of these benefits if you keep the skin on, so avoid peeling your mid-afternoon snack.
What’s more, the high fibre content in apples means they serve up a healthy dose of prebiotics (undigestible fibre that the “good” bacteria in your gut eat). “Prebiotics may improve gastrointestinal health as well as potentially enhance calcium absorption,” says Caspero.

What are the health benefits of eating apples?
Help manage weight
Because apples are full of fibre that can help you feel fuller for longer, they’re a great fruit to help keep your weight steady. A study from the Journal of Functional Foods found that regular apple consumption has been linked to lower lipid levels and a reduced risk of obesity. Caspero explains that “Eating high-fibre snacks [like apples] has been shown to aid in satiation and therefore can decrease overall calorie consumption during the day.” Both of these factors mean that they can help contribute to weight management.
They keep your heart healthy
According to Palinski-Wade, “apples are rich in the compound quercetin, which has been shown to reduce inflammation while fighting against heart disease and hypertension.”
They do keep the doctor away
It turns out there’s some truth to the old adage. In a large study from JAMA Internal Medicine, participants who ate at least one small apple per day required fewer doctor visits, hospital stays and prescription medications than those who didn’t eat apples.
