Raw Spinach Calories Per Cup And Per 100 Grams
Spinach is feather-light when uncooked, so a huge bowl barely dents your daily energy budget. One cup of loose leaves (about 30 grams) lands near 7 calories. Weigh out 100 grams and you get roughly 23 calories. Both figures come from datasets used by dietitians and researchers across the U.S.
Why such tiny numbers? Raw leaves are mostly water with modest fiber and protein, and only a trace of fat. That composition explains the low energy density and the way a salad can feel generous in volume while staying lean on calories.
Serving Sizes That People Actually Use
Kitchen measures vary. A “cup” depends on how tightly you pack the leaves, and “a handful” differs by person. Use the table below to ballpark common amounts without a scale, then adjust to taste.
| Portion | Weight (Approx.) | Calories |
|---|---|---|
| 1 cup loose leaves | 30 g | ~7 kcal |
| 2 cups loose leaves | 60 g | ~14 kcal |
| 1 packed cup | 40–45 g | ~9–10 kcal |
| 1 ounce | 28 g | ~6–7 kcal |
| 100 grams | 100 g | ~23 kcal |
| 1 large leaf | ~10 g | ~2–3 kcal |
| Small “side salad” | ~60–75 g | ~14–17 kcal |
For diet planning, these counts sit inside a bigger picture—once you set your daily calorie needs, leafy greens make volume possible without a heavy energy load.
How Raw Portions Compare With Cooked Spinach
Heat wilts greens and squeezes the pile down. The calories don’t magically rise; the leaves just lose water and pack tighter into a cup measure. That’s why a cup of cooked spinach looks tiny next to the same weight of raw leaves. If you compare by weight, 100 grams of cooked spinach still sits near the same calorie total per 100 grams; the big swing you’ll see is in vitamin K concentration per cup because the cup now weighs much more.
Quick conversion cues help at the store and at home: dietary guidance counts two cups of leafy salad greens as one cup-equivalent of vegetables. That explains why salad recipes often call for what looks like a mountain of leaves.
Macros, Fiber, And Satiety
A 100-gram portion brings about 3.6 grams of carbs, 2.2 grams of fiber, and 2.9 grams of protein. Those are small absolute amounts, but the fiber supports fullness while keeping calories low. This is one reason raw leaves show up in weight-friendly salads and wraps.
Where The Calories Come From
Energy splits across small contributions from carbs, protein, and a trace of fat. On a gram-for-gram basis that spread looks balanced, yet the total still lands under 25 calories per 100 grams because water dominates the weight.
Why Nutrients Still Matter When Calories Are Tiny
Leafy greens help with vitamins and minerals that many menus miss. Spinach stands out for vitamin K, folate, vitamin A precursors, and potassium. It’s common to see 100 grams deliver over 400% of the daily value for vitamin K, double-digit percentages for potassium and iron, and a healthy bump of vitamin C.
Micronutrient Snapshot (Per 100 Grams)
The numbers below come from a USDA-based dataset widely used by clinicians and nutrition tools.
| Nutrient | Amount | %DV |
|---|---|---|
| Vitamin K | ~483 µg | ~402% |
| Vitamin C | ~28 mg | ~31% |
| Iron | ~2.7 mg | ~15% |
| Calcium | ~99 mg | ~8% |
| Potassium | ~558 mg | ~12% |
| Folate (DFE) | ~194 µg | ~49% |
| Beta-carotene | ~5,626 µg | — |
Vitamin K shows up in abundance here. The NIH’s overview lists spinach among the main sources in U.S. diets, which is why people on certain medications often get consistent-intake advice rather than avoidance.
Portion Strategies For Meals And Snacks
Salads That Stay Light
Start with 2–3 cups of raw leaves for a base that stays under 20 calories. Add crunch from cucumbers or radishes, a sweet note from orange segments, and a protein like chickpeas or grilled chicken. The dressing calls the shots on the final calorie total, so measure oils and creamy add-ins rather than pouring freehand.
Smoothies With Greens, Not Sugar
For a breakfast or workout snack, blend a cup of leaves with unsweetened yogurt, a small banana, and a splash of milk or water. That keeps the drink thick and bright without a syrupy load. Oats or chia add fiber if you want extra staying power.
Sandwiches, Wraps, And Bowls
Use a generous handful as a sandwich layer or burrito filler to bulk up volume. In grain bowls, raw leaves tame heavy toppings and bring a fresh note next to roasted veggies or beans. A squeeze of lemon wakes up the flavor with almost no calories.
Common Calorie Mistakes To Avoid
Dressing And Oil Miscounts
Leaves are light; oils aren’t. A tablespoon of olive oil adds about 119 calories—tasty, and worth it when measured, but an easy way to turn a lean salad into a calorie-dense plate if the pour gets heavy. Choosing a measured spoon or a spray bottle keeps totals honest.
“Healthy” Toppings That Sneak In Energy
Nuts, seeds, cheese, dried fruit, and croutons bring texture and flavor. They also stack calories fast. Pre-portion them, or pick one accent at a time rather than a handful of everything.
Label Literacy For Raw Greens
Store-bought boxes often print nutrients “per serving,” and that serving might be as low as 30 grams. If your bowl holds triple that amount, multiply the numbers. When in doubt, weigh once to calibrate your eye. For authoritative reference values, check the USDA’s nutrient database entries for leafy greens.
How Much Raw Spinach Fits Daily Veggie Targets?
Dietary guidance treats two cups of leafy salad greens as one cup-equivalent of vegetables. If your daily goal is two to three cup-equivalents, you could mix a big salad with other veggies and reach your mark with ease. That way you stay full while keeping calories modest.
Key Facts, In One Place
Quick Numbers You Can Use
Per cup (30 g): ~7 calories, ~1.1 g carbs, ~0.9 g protein. Per 100 g: ~23 calories, 3.6 g carbs, 2.2 g fiber, 2.9 g protein. These values line up across multiple USDA-based tools that dietitians rely on in clinics and apps.
Why The Cup Measure Feels Confusing
Leaf volume changes wildly with packing and with moisture on the leaves. If you rinse and spin thoroughly, the cup weight is more consistent. Still, the easiest way to compare recipes and labels is by grams—30 grams for a cup of raw leaves is a reliable planning number across references.
Helpful Sources For Deeper Detail
The USDA-based profile gives nutrient totals per 100 grams, and the NIH vitamin K sheet explains why greens contribute so much to that vitamin in daily diets.
