Spinach: Complete Macros & Nutrition Guide

Spinach Macros: Complete Nutrition Guide

For anyone on a journey to optimize their health, manage weight, or build muscle, understanding the macros and nutrition facts of the foods we eat is paramount. As the JustMacrosFit team, we believe in empowering our community with comprehensive insights into foundational ingredients. Today, we're diving deep into spinach, a leafy green powerhouse often hailed as a superfood, to uncover its full nutrition facts and explain why it deserves a prime spot in your diet.

Quick Answer

Spinach is a remarkably low-calorie vegetable, offering an excellent source of micronutrients with minimal impact on your daily macros. Per 100g of raw spinach, you can expect approximately 23 calories, 3.6g of carbohydrates, 2.9g of protein, and a mere 0.4g of fat, making it an incredibly nutrient-dense food. Its standout feature is its exceptional vitamin K content, vital for bone health and blood clotting.

Detailed Nutrition Facts

When we delve into the nutrition facts of spinach, we discover a treasure trove of health-promoting compounds. Whether raw or cooked, spinach remains a champion for its impressive micronutrient profile, all while keeping its calorie and macro counts remarkably low.

A 100-gram serving of raw spinach contains roughly:
* Calories: 23
* Carbohydrates: 3.6g
* Fiber: 2.2g
* Sugars: 0.4g
* Protein: 2.9g
* Fat: 0.4g

This macro breakdown highlights spinach as a fantastic source of dietary fiber, contributing to satiety and digestive health without adding significant calories. The protein content, while not massive, is notable for a leafy green, making it a valuable addition to plant-based diets.

Beyond the macros, spinach shines brightly in its micronutrient offerings. It's packed with vitamins and minerals essential for countless bodily functions:

• Vitamin K: Crucial for blood clotting and bone health, providing well over 100% of the Daily Value (DV) in a single serving.
• Vitamin A (as beta-carotene): Important for vision, immune function, and skin health.
• Vitamin C: A potent antioxidant that supports immune health and collagen production.
• Folate (Vitamin B9): Essential for cell division and DNA synthesis, particularly important during pregnancy.
• Iron: Vital for oxygen transport in the blood, though the non-heme iron in spinach is best absorbed with Vitamin C.
• Magnesium: Involved in over 300 enzymatic reactions, supporting muscle and nerve function, blood glucose control, and blood pressure regulation.
• Manganese: Important for bone development, metabolism, and antioxidant defenses.
• Potassium: Crucial for maintaining fluid balance and healthy blood pressure.

When considering serving sizes, remember that raw spinach significantly reduces in volume when cooked. A cup of raw spinach is a very small amount by weight (around 30g), whereas a cup of cooked spinach is much denser (around 180g). This means a greater nutrient intake per volume when consumed cooked. Compared to similar foods like romaine lettuce, spinach offers a far superior micronutrient density and generally higher fiber and protein per serving. Even against other leafy greens like kale, spinach often holds its own, particularly in iron and Vitamin K content.

Health Benefits

Incorporating spinach into your diet brings a cascade of health benefits, making it an indispensable food for virtually everyone. The JustMacrosFit team consistently champions foods that provide a broad spectrum of advantages, and spinach is a prime example.

One of spinach's primary benefits lies in its powerful antioxidant and anti-inflammatory properties. These compounds help combat oxidative stress and reduce inflammation in the body, which are underlying factors in many chronic diseases. The high concentration of vitamin K contributes significantly to bone health, playing a critical role in bone mineralization and reducing the risk of osteoporosis. We often recommend it for individuals looking to support a strong skeletal system.

Hero Nutrients: Spinach is an exceptional source of Vitamin K, Vitamin A, and Folate, all vital for robust health.

Spinach is also a friend to your cardiovascular system. Its potassium content helps regulate blood pressure, while nitrates present in spinach have been shown to improve blood flow and reduce blood pressure. For those concerned with vision, the carotenoids lutein and zeaxanthin in spinach are crucial for eye health, protecting against age-related macular degeneration and cataracts.

* Pregnant women: Its high folate content is crucial for fetal development.

When to eat it? Spinach is incredibly versatile and can be enjoyed at any meal. We encourage our members to add it to breakfast smoothies, lunch salads, or dinner stir-fries. There's no wrong time to boost your nutrient intake with this green powerhouse.

How to Track Macros

Accurately tracking your macros is key to achieving your fitness and health goals. With a nutrient-dense food like spinach, understanding portion measurement is crucial, especially given its volume reduction when cooked.

For precise macro tracking, we always recommend using a digital kitchen scale. This allows you to measure your food in grams, which is far more accurate than volumetric measurements (like cups) that can vary widely.

• Raw Spinach: A standard serving might be 30g (about 1 cup loosely packed) or 100g. If using cups, be mindful of how densely you pack it.
• Cooked Spinach: This is where weight measurement becomes even more critical. A cup of cooked spinach can weigh significantly more than raw. Aim for 90-180g (0.5 to 1 cup) depending on your meal and goals.

When using macro tracking apps, like JustMacrosFit, you can search for "Spinach, raw" or "Spinach, cooked" and enter the weight in grams for the most accurate data. Many apps also provide common serving sizes in cups, but for true precision, especially when you're meticulously hitting specific macro targets, a scale is your best friend. Remember, consistent tracking helps you understand your intake patterns and make informed adjustments.

For Weight Loss

For individuals focusing on weight loss, spinach is an unparalleled ally. Our experience as nutrition coaches tells us that success in weight management often hinges on choosing foods that are both satisfying and low in calories, and spinach fits this description perfectly.

Key Data: A generous 100g serving of raw spinach contains only 23 calories, making it a powerful volume food for weight loss.

Spinach's incredibly low calorie density means you can consume a significant volume of it without significantly impacting your daily calorie budget. This "volume eating" strategy is highly effective because it helps you feel full and satisfied, reducing the likelihood of overeating higher-calorie foods. The high fiber content in spinach further contributes to satiety, slowing digestion and stabilizing blood sugar levels, which can curb cravings.

Portion Recommendations: We encourage our members to be generous with spinach. Aim for at least 1-2 cups of raw spinach per meal, or 0.5-1 cup cooked. Don't be shy about adding extra handfuls to your scrambles, soups, or even just wilting a large batch as a side dish.

Pairing Suggestions for Weight Loss:
* Lean Protein: Combine spinach with lean protein sources like grilled chicken breast, fish, tofu, or lentils. The protein and fiber combination is incredibly satiating.
* Healthy Fats: A small amount of healthy fats (avocado, nuts, seeds, olive oil) with spinach can enhance the absorption of fat-soluble vitamins and add to satisfaction.
* Whole Grains: Pair spinach with moderate portions of whole grains (quinoa, brown rice) for sustained energy and additional fiber.

For Muscle Gain

While spinach isn't going to build biceps on its own, it plays a critical supporting role in muscle gain programs. The JustMacrosFit team understands that muscle growth isn't just about protein; it's about a holistic nutritional approach that includes micronutrients for recovery, energy, and overall cellular health.

Spinach's protein content, while modest, contributes to your overall daily protein intake, especially when consumed in larger quantities as part of a varied diet. More importantly, spinach is rich in micronutrients that support muscle function and recovery:

• Magnesium: Essential for muscle contraction and relaxation, and helps prevent cramps. It's also involved in ATP (energy) production.
• Potassium: Crucial for fluid balance and nerve signals that control muscle movement.
• Iron: Vital for oxygen transport to working muscles, improving endurance and reducing fatigue.
• Nitrates: Studies suggest that the nitrates in spinach can enhance exercise performance by improving muscle efficiency and reducing the oxygen cost of exercise.

Pre/Post Workout Timing:
* Pre-workout: Adding spinach to a pre-workout smoothie or meal can provide nitrates and micronutrients to support energy and performance.
* Post-workout: Incorporate spinach into your post-workout meals to replenish electrolytes, aid in recovery with its anti-inflammatory compounds, and contribute to overall nutrient repletion.

Bulking Meal Ideas:
