Heating Blueberries

I really love zero yogurt and got blueberries. I am wondering now I am counting calories, would I need to add extra calories? I only hear them for 30 seconds in the microwave so they are oosing - then add 2 big spoons of zero yogurt. Good heaven!

If you are asking...
Does microwaving increase calories in blueberries? No, but theoretically some water may evaporate. Just measure the blueberries before you heat them and use the raw blueberry entry.
Do I need to count calories from blueberries? Yes. Weigh (by preference) the blueberries, or measure by volume.
Do I need to count the calories from my blueberry and yogurt snack? Yes. Even low cal snacks add up over the course of the day.
Hope that helps.0 -
Blueberries have calories so weigh the amount you are going to eat and log then accordingly0

Count all foods you consume
It makes no difference if they are oozing or not.
Weigh all your solids with a food scale. Measuring cups for liquids.0 -
Have you got a weigh scale yet? That will tell you how many calories you are getting from your zero fat yogurt and your blueberries. With MFP you count the calories of everything you consume.0
-
Is the question about the fact that the blueberries were heated, whether or not that might negate some/all of the calories in them and thus make it unnecessary to log them?
Just wanted to make sure I was understanding the original question because I feel I must be missing something otherwise.0 -
Yes, count the calories for both the yogurt and the blueberries. Microwaving will not change the calorie count.0

Thank you. I was told that any fruit which has been heated will release sugsrs making it more calorific, hence the question.0

0.001 calories per gram per degree C of extra temperature is the number of calories to add for heating, approximately.
100g of blueberries at 40 C compared to 20C = 2 extra calories.0 -

Thank you.. I think people though I was going mad with the replies here. It's very minimal calories but answers it perfectly.0 -

Heating it does, see other comment.0 -

Why would I think it would negate any calories? When you heat fruit, it releases the sugars and hence more calorific. I want to ensure I'm counting every calorie. So.. no I'm not trying to Not Log them.. the complete opposite! See the other reply to my question.0 -

Yes I am but the question was if there were more calories to count..and I can see from Yarwell that there are.0 -

Does heating blueberries increase calories? Yes.. See Yarwell's reply here. Although minimal, they are still EXTRA calories.

Yes of course they have calories, and more when heated which I am now aware of thanks to a reply from Yarwell.0 -
This is my favorite thread.
Thank you. Others have replied as if it was a dumb question and I was trying to get out of adding the food calories... It was the opposite in fact I don't know why people had to assume I was trying to get away without adding the food calories lol. When I was asking about the extra calories fruit has when it's heated. Thanks again.0 -
I did not know that.0

100g of blueberries at 40 C compared to 20C = 2 extra calories.
What counts as "extra" temperature? Like, what's the baseline on which one would expect the USDA calorie count for blueberries was calculated?0 -
OP, don't drive yourself too crazy with this. Blueberries that were harvested a couple days earlier than others will have less calories than the later harvest, ones that grew in even slightly higher temperature environments will also be slightly higher... unless you know the absolute minutiae of the temperature at which the berries grew through the whole process, the extra cals from microwaving won't make a bit of difference, and really wouldn't be accurate in any event, as there is up to a 20% margin of error in any recorded calorie count.0

FWIW, perhaps an interesting read on the subject for the unfamiliar (come to your own conclusion; there's plenty of room for more research): http://blogs.discovermagazine.com/crux/2011/12/08/why-calorie-counts-are-wrong-cooked-food-provides-a-lot-more-energy/#.Vs1yAa2-3n40

I also find this interesting-thanks OP. However, I agree that the change in calories is minimal and won't sabotage your weight loss. Good on you for wanting to be accurate--we need more people like you.0

So heating blueberries adds calories? How? Does the microwave add sugar? I think it might just be a matter of "concentrating" the calories rather than adding any. Experiment A: So if you take 100 gr of raw berries, microwave them and weigh them again - do they now weigh less? Do they contain the same amount of sugar? Does sugar evaporate? Is life too short? Weigh your berries, log them, eat them - any which way you like. :-)0

That's what I'm wondering. Is it dehydration altering the weight or does the heating change the structure or chemical composition.0 -
I like heating berries to have with yogurt and I will add the extra 2 per 100g. It may to miniscule but so is thinking a tsp of sugar isn't worth adding. I'm hoping to Change my way of eating by counting each calorie to lose weight.. after all it's because of my "not counting" the off thing here and there.. Why I am here and over weight.!
So... A Fresh look and all that.. thanks for all your comments.0 -

Above room temperature or whatever base temperature USDA use.
I don't know the convention in nutrition, but in Thermodynamics generally either 0 or 25 C tend to be common.
"Atwater and Rosa (63) defined the Calorie at 20°C and noted that it was slightly larger than the 18°C unit employed by Armsby (64)." according to http://jn.nutrition.org/content/136/12/2957.full0 -
I have learned something new today! who'd have thought heated fruit = a few more cals....0
