Diet Ratings
Miso paste is fermented and relatively low-carb (1-2g net carbs per tablespoon). A simple miso soup with tofu and seaweed contains 2-5g net carbs per serving. However, some recipes add noodles or starchy vegetables.
iStrict keto practitioners may avoid miso due to its carbohydrate content and fermented nature affecting ketone production, though evidence for this is limited.
Miso paste is fermented soybeans and is plant-based. Traditional miso soup with tofu, seaweed, and vegetable broth is fully vegan.
Miso is fermented soy (legume). Soy is excluded on paleo diet. Tofu often added is also soy-based.
Asian soup with fermented soy and minimal processing. Contains beneficial probiotics but not Mediterranean. High sodium from miso paste is a concern.
iSome Mediterranean diet researchers acknowledge fermented foods like miso as compatible with gut health principles, though not traditional to the diet.
Miso is fermented soy (legume), and soup typically contains seaweed, tofu, and vegetables. Soy is plant-derived and excluded from carnivore diet.
Miso is made from fermented soybeans. Soy is explicitly excluded from Whole30 as a legume.
Miso paste itself is low-FODMAP in small amounts (1 tablespoon per Monash). However, traditional recipes often include green onion, tofu, and dashi broth. The soup is safe only if prepared without high-FODMAP additions and consumed in moderate portions.
iMonash University rates miso paste as low-FODMAP at 1 tablespoon, but clinical practitioners often caution that fermented soy products may trigger symptoms in sensitive individuals despite low FODMAP content. Serving size and added ingredients are critical.
Miso paste is extremely high in sodium (one tablespoon contains ~600mg). While it contains beneficial probiotics and umami, sodium content makes it problematic for DASH. Acceptable only in very small portions.
Fermented soy provides protein and probiotics; broth is low-glycemic. However, miso is sodium-dense and often served with tofu (incomplete protein profile). Typically lacks sufficient protein and fat for Zone balance without additions. Sears emphasizes complete protein sources.
iSome Zone practitioners accept miso soup as a light appetizer or side, not a standalone meal, due to incomplete macronutrient profile.
Fermented miso provides probiotics and beneficial enzymes. Seaweed offers iodine and polysaccharides. Typically low-calorie with minimal inflammatory ingredients. Tofu adds plant protein.
Miso soup is light, easy to digest, and naturally low in fat. It provides fermented probiotics beneficial for GLP-1-induced digestive changes, contains some protein from miso and tofu (if included), and has high water content supporting hydration. The broth-based nature makes it ideal for small portions while feeling satisfying.
