Calories in Miso Paste: Nutritional facts for Miso Paste Types

A 100g serving of Miso Paste provides 198 calories.

One kilogram (1000g) of Miso Paste supplies 1980 calories.

A single tablespoon of Miso Paste (17g) contains 33.7 calories, while a single teaspoon of Miso Paste (6g) provides 12 calories. Retail brands offer distinct energy profiles, as a serving of Chikuma Miso Paste (18g) contains 30 calories. A serving of Hikari Miso Organic Dashi Miso (12g) provides 25 calories.

The health benefits of miso paste include providing probiotics and essential enzymes derived from the fermentation of soybeans with salt and koji. The paste aids in digestive health and supports immune function due to the presence of beneficial bacteria. 

• Supports Gut Health: The fermentation process generates probiotics, specifically Aspergillus oryzae, which maintain a healthy microbiome balance. Research by Jayachandran, M., & Xu, B. (2019), "An insight into the health benefits of fermented soy products," confirmed that regular consumption of miso improves gut flora diversity and digestive efficiency.
• Provides Antioxidant Protection: Soybeans contain isoflavones and phenolic acids that neutralize free radicals and reduce oxidative stress. A study by Ito, K., et al. (2017), " The Effects of the Habitual Consumption of Miso Soup on the Blood Pressure and Heart Rate of Japanese Adults: A Cross-sectional Study of a Health Examination," established a correlation between miso consumption and reduced risk of lifestyle-related diseases due to high antioxidant activity.
• Enhances Nutrient Absorption: The enzymes produced during fermentation break down antinutrients in soybeans, increasing the bioavailability of minerals like zinc and iron. Research by Fidler, M. C., et al. (2003), "Iron absorption from fish sauce and soy sauce fortified with sodium iron EDTA," noted that fermented soy products facilitate better mineral uptake compared to unfermented soy.

The downsides of miso paste involve risks regarding high sodium content and potential allergen exposure when consumed in large quantities. Nutritionists advise limiting intake to one tablespoon (17g) per day and choosing Chickpea Miso as a soy-free, lower-sodium alternative to mitigate potential risks. 

• Elevates Sodium Levels: Excessive intake contributes to daily salt limits, potentially straining the cardiovascular system. Research by He, F. J., et al. (2013), "Effect of lower salt intake on blood pressure and risk of cardiovascular disease," found that even moderate reductions in sodium intake significantly lower blood pressure and stroke risk.
• Contains Soy Allergens: The soybean base presents a severe risk for individuals with soy sensitivities or allergies. Research by Savage, J. H., et al. (2010), "The natural history of soy allergy," identified soy as a persistent allergen that requires strict avoidance for sensitized populations.
• Risks Histamine Intolerance: Fermentation produces biogenic amines which trigger headaches or allergic-like reactions in sensitive individuals. A study by Toro-Funes N., et al. (2014), " Biologically active amines in fermented and non-fermented commercial soybean products from the Spanish market," detected significant levels of histamine in aged miso samples.

Yes, miso paste is good for health because the probiotics support gut flora and the soy base provides complete proteins, provided the sodium intake remains controlled. Cardiovascular health benefits from the presence of soy isoflavones which improve arterial flexibility as explored by Ito, K. (2020), "Review of the health benefits of habitual consumption of miso soup." Digestive health improves through the introduction of beneficial bacteria from the fermentation process as confirmed by Jayachandran, M., & Xu, B. (2019), "An insight into the health benefits of fermented soy products." Cellular health enhances due to the antioxidant capacity of compounds formed during fermentation as detailed in the study by Santiago, L. A., et al. (1992), "Japanese soybean paste miso scavenges free radicals and inhibits lipid peroxidation."

Calories change according to miso paste types based on the fermentation duration and the ratio of soybeans to grains like rice or barley. White Miso contains the highest energy load per 100g due to the shorter fermentation period and higher rice content, which retains more carbohydrates and sugars. Red Miso offers a reduced profile as the extended fermentation process breaks down more starches and the recipe relies more heavily on protein-rich soybeans. Mixed Miso provides a moderate caloric density per serving because the product blends the carbohydrate-heavy white variety with the protein-dense red variety.

The origin of miso paste dates back to ancient China, where a fermented soybean paste known as "jiang" or "chi" existed as early as the 4th century BC. Buddhist monks introduced the precursor to miso to Japan during the 7th century AD. Japanese artisans refined the process during the Muromachi period by grinding the soybeans into a paste rather than leaving them whole, creating the texture known today. The condiment became a critical source of protein and salt for samurai during the Sengoku period. Industrial production expanded in the 20th century, establishing miso as a global symbol of Japanese gastronomy.
