Macronutrients and Calories in 3 oz of Spinach
A 3-ounce (85g) serving of spinach is remarkably low in calories, with most sources indicating it contains around 20-23 calories. This makes it an ideal food for weight management, as it provides a large volume of food with minimal caloric impact. The macronutrient profile is also lean and health-focused.
- Carbohydrates: A 3 oz serving provides about 3 grams of carbohydrates, a large portion of which is dietary fiber.
- Protein: Spinach offers a modest amount of plant-based protein, typically around 2 grams per 3 oz serving.
- Fat: This leafy green is nearly fat-free, containing less than half a gram of fat in a 3 oz serving.
The Powerhouse of Micronutrients
While the macronutrient count is low, the real value of spinach lies in its micronutrient content. This small serving size packs a significant punch of vitamins and minerals.
- Vitamin K: Spinach is one of the richest dietary sources of Vitamin K1. A 3 oz serving can provide over 400 micrograms (mcg), far exceeding the daily recommended value. Vitamin K is crucial for blood clotting and bone health.
- Vitamin A: Rich in carotenoids like beta-carotene, spinach is a potent source of Vitamin A. A 3 oz serving can contribute a large percentage of your daily Vitamin A needs, supporting vision and immune function.
- Vitamin C: This powerful antioxidant is present in spinach, helping to boost immune function and promote skin health. The amount can vary slightly depending on whether it's raw or cooked.
- Iron: Often associated with iron, spinach contains non-heme iron. While a 3 oz serving contributes a notable percentage of the daily value, pairing it with Vitamin C-rich foods enhances absorption.
- Folate (Vitamin B9): Crucial for cellular function and growth, especially for pregnant women, folate is abundant in spinach.
- Magnesium: An essential mineral involved in hundreds of bodily processes, magnesium content is significant in spinach.
- Potassium: With its high potassium levels, spinach helps relax blood vessels, which in turn can lower blood pressure.
Raw vs. Cooked Spinach: A Comparison
Different preparation methods can alter the nutrient availability in spinach. Cooking can shrink the leafy greens, concentrating some nutrients while decreasing others. Raw spinach contains oxalic acid, which can bind to minerals like iron and calcium and limit their absorption.
| Nutrient | 3 oz Raw Spinach | 3 oz Cooked Spinach | Notes |
|---|---|---|---|
| Calories | ~20 | ~40 | Cooked spinach is more concentrated in calories per weight due to water loss. |
| Vitamin K | Very high | Also very high | Both forms are excellent sources of Vitamin K. |
| Vitamin A | High (from carotenoids) | Very High | Cooking helps release more Vitamin A for absorption. |
| Vitamin C | High | Lower | Vitamin C is heat-sensitive and decreases with cooking. |
| Iron | Moderate | Higher (more bioavailable) | Cooking helps reduce the effect of oxalic acid, improving iron absorption. |
| Fiber | Moderate | Higher (more concentrated) | Cooking concentrates the fiber, and it may be more easily digested. |
