How Many Calories Are In 100G Blueberries? | Quick Bite Guide

Calories In 100 Grams Of Blueberries — What You Get

Per 100 grams of raw berries, you’re looking at about 57 calories with a light 0.3 g of fat, ~14.5 g of carbs, ~9.96 g of sugars, ~2.4 g of fiber, and ~0.7 g of protein. Those figures line up with the USDA-derived data compiled by MyFoodData and mirror cup-size labels when scaled to the same weight. You also get vitamin C and vitamin K along with manganese in helpful amounts for the size of the serving. The numbers below help you convert that 100-gram reference to common bowls and scoops drawn from the same database.

Quick Nutrition Table For 100 g And Everyday Portions

Portion	Weight (g)	Calories
Standard Reference (raw)	100	57
1 cup raw	148	84
50 berries (avg.)	68	≈38
1 oz (handful)	28	≈16

The 100-gram yardstick makes label math easy, but most of us pour a cup into yogurt, a smoothie cup, or a cereal bowl. At that size you’re in the mid-80s for calories with about 3.6 g of fiber and roughly 15 g of natural sugar, per the same dataset sourced from USDA FoodData Central.

Why Blueberries Work In A Calorie-Aware Plan

Low energy density means you get volume and sweetness for not many calories, which helps with satiety. The skins carry much of the fiber, giving texture and slowing down the sugar rush. That balance is handy at breakfast or as a mid-afternoon fix when you want something sweet without a heavy tally.

Fiber matters for fullness and digestive rhythm. If you’re calibrating targets, scan your recommended fiber intake and stack your day with fruits, vegetables, legumes, and whole grains to hit the mark without supplements.

What About Sugar?

Blueberries bring roughly 10 g of naturally occurring sugars per 100 g. Pairing them with protein or fat—say, Greek yogurt or a spoon of peanut butter—tempers the glycemic kick and keeps you full longer. For general guidance on daily fruit patterns and smart swaps across forms (fresh, frozen, canned, dried), the USDA’s fruit page lays out simple ground rules in plain language.

Micronutrients Per 100 Grams (Raw)

Beyond the macro snapshot, a 100-gram serving offers vitamin C (~9–10 mg), vitamin K (~20–30 µg), and manganese (~0.3–0.5 mg). That’s a tidy package for skin health, clotting, and enzyme function, especially when you regularly rotate berries into meals. The values below reflect the same source used for the opening math and map neatly to cup-size labels.

Nutrient	Per 100 g	%DV
Vitamin C	~9.7 mg	~11%
Vitamin K	~19–29 µg	~16–24%
Manganese	~0.33–0.50 mg	~14–22%

These ranges come from the same USDA-derived dataset aggregated by MyFoodData, which lists cup values and dynamically converts to 100 g. It’s a handy way to keep serving math straight without hunting through multiple entries.

Fresh Vs. Frozen Vs. Dried — Calories And Sugar Per 100 g

Form changes density. Water loss shifts the numbers even when the fruit is the same. Here’s a side-by-side for unsweetened options and a common sweetened dried entry so you can see the spread.

Form (unsweetened unless noted)	Calories / 100 g	Sugar / 100 g
Fresh (raw)	~57	~9.96 g
Frozen (unsweetened)	~51–57	~9–10 g
Dried (sweetened, common)	~300+*	High

*Brand recipes vary widely. Frozen unsweetened blueberries hover near fresh on a per-100-gram basis, while dried versions concentrate sugars and calories as water drops out. Source snapshots: MyFoodData entries for raw and frozen blueberries, and representative dried products.

Serving Ideas That Keep The Count Honest

Breakfast Builds

Greek yogurt bowl: Start with a plain base, fold in 75–100 g of blueberries, add a sprinkle of oats or nuts. You keep sugar natural and bump protein for staying power.

Overnight oats: Stir berries into the jar in the morning, not the night before, to keep them plump and bright. A 100-gram scoop works well across most oat mixes.

Smoothies Without A Sugar Bomb

Use frozen unsweetened blueberries to chill the drink without extra ice. Blend with milk or kefir and a small nut-butter spoon. You get flavor, color, and fiber without pushing calories through the roof. Frozen nutrition per 100 g stays close to fresh when no syrup is added.

Smart Snacks

Pair a 100-gram handful with a boiled egg, cottage cheese, or a few almonds. That mix smooths the blood-sugar curve and stretches satiety.

Label Clues When You Buy

Fresh Clamshells

Look for bloom (that dusty white film), springy skins, and a dry bottom. Weight varies by size and water content. If you’re aiming for a known calorie target, weighing once or twice at home pays off—your eye learns fast.

Frozen Bags

Pick “unsweetened” and scan the ingredient list for only blueberries. Nutrition lines should mirror the fresh profile after you normalize for weight. Anything with syrup or added sugar climbs in a hurry. MyFoodData’s frozen entries are a solid reference point.

Dried Pouches

Most retail options are sweetened; calorie counts jump per 100 g. Reserve small portions for trail mixes or toppings. If the ingredient list shows sugar or juice concentrates, you’re not getting the same per-weight profile as fresh fruit. Representative product entries show three-to-six-times the calorie density.

Portion Conversions You’ll Use

How Much Is 100 Grams In Kitchen Terms?

It’s a rounded ⅔ cup for many lots of berries, though berry size moves the needle. A full level cup of raw blueberries averages ~148 g in the USDA-derived tables, which lands near 84 calories. If you don’t want to weigh every time, use a small bowl or a standard measuring cup as your visual cue.

How This Fits Into Daily Fruit Goals

USDA guidance points most adults toward about two cup-equivalents of fruit per day. Whole fruit beats juice for fiber and satisfaction, and frozen counts when it’s just fruit. That makes a 1-cup blueberry bowl an easy win on busy days.

Kitchen Tips To Keep Calories Predictable

Wash Right Before Eating

Rinse under cool water and drain well to keep skins snappy. Soaking can soften texture and add water weight, which throws off a tight gram target.

Batch Prep For Speed

Portion 100-gram bags for the freezer. Label by weight so smoothie mornings stay automatic, and your macro log stays tidy.

Sweetness Without Extra Sugar

Zest lemon or grate a little ginger over a bowl. Acid and spice amplify flavor so you don’t reach for syrups or honey.

Health Context In One Place

Blueberries are a fruit first and a snack second: low sodium, no cholesterol, and useful micronutrients per bite. The USDA-derived page at MyFoodData lists ~2.4 g of fiber per 100 g, which helps with regularity and meal satisfaction. If you’re balancing a day of meals around fiber, berries can fill gaps without pushing calories.

When You’re Tracking Closely

Weigh once at home to confirm your usual bowl or cup. Most labels and databases round values; a small kitchen scale brings your log in line with what you’re actually eating.

Troubleshooting Common Questions

Do Wild Berries Change The Count?

Wild varieties can be smaller and a touch denser, but per-100-gram values sit close to standard fresh numbers when no sugar is added. Always check the package; “juice sweetened” or “syrup” wording means a different profile.

Can You Just Swap Fresh And Frozen?

Yes, when the bag is unsweetened. Per-weight calories are similar; texture and vitamin C shift a little with freezing and thawing, which you’ll mainly notice in smoothies and baked goods.

Bottom Line

Per 100 grams, blueberries stay light on calories, bring natural sweetness, and carry fiber plus helpful vitamins and minerals. Fresh or frozen unsweetened options are easy to fit into breakfasts, snacks, and desserts without blowing a target. If you grab dried berries, keep portions modest; the math climbs fast as water leaves.
