Jess: Hey Adam, that is a good question. For a little Miso baseline...Miso soup is a japanese soup that is actually highly touted in Japan for its many health and nutritional benefits. Miso, similarly to soy paste and tempeh is actually a type of fermented soy protein which has been more recently studied in western cultures throughout the 20th century due to their health benefits in r/t phytochemicals (1) and isoflavones (2). In 1999 the U.S. FDA actually approved the food label health claim in the prevention of coronary artery disease. (more info Jess The RD Nutrition Facts Panel/Health Claims)
So, is miso soup high in iron? For a health claim to be "high" indicates that the product must contain 20% of your dietary recommendation for a specific item. The dietary recommendation for iron per the Food and Nutrition Board at the Institute of Medicine recommends...
Infants and children
7 months to 1 year: 11 mg/day
1 to 3 years: 7 mg/day
4 to 8 years: 10 mg/day
Males
14 to 18 years: 11 mg/day
Age 19 and older: 8 mg/day
Females
14 to 18 years: 15 mg/day
19 to 50 years: 18 mg/day
51 and older: 8 mg/day
Unfortunately based on multiple nutrition label evaluations, miso soup is NOT a high iron food. It frequently ranges from 5-8% the recommended daily intake of iron. Look at this list of the Top 10 Iron Rich Foods - WebMD for some high iron options. A traditional miso soup recipe includes miso, vegetables and tofu. It is believed to be a detoxifying agent to potentially prevent cancers, digestive, and heart concerns. it is even believed to improve cognition and mental focus! So, although this item is frequently high in sodium (740-1100mg in 1 serving) it still has some positive health claims for an item to be consumed in moderation. Also, you will find many high iron foods would actually be a great accompaniment in your Miso soup to add a little nutritional bang EX: dark leafy greens, beans, iron rich grains.

Wakame
A seaweed packed with the antioxidant compound fucoxanthin.
It can be tough, so use kitchen shears to cut it into smaller pieces.
Dashi
It's pretty much the chicken bouillon of Japan. Made from dried fish flakes and seaweed, dashi is what gives miso soup its signature subtle fish flavor and light amber color. Dashi comes in three forms, all of which can be used to whip up instant miso: powdered, liquid concentrate, and stuffed in a handy packet like the one used in the recipe above.
