Seaweed is a marine algae packed with micronutrients, but its carbohydrate content varies depending on the type. For individuals following a ketogenic diet, understanding these differences is crucial. This article explores the keto-friendliness of various seaweeds and offers guidance on incorporating them into your diet.
Understanding Carbohydrates in Seaweed
The carbohydrate content is a key factor in determining whether a food is keto-friendly. Different types of seaweed contain varying amounts of carbs, influencing their suitability for a ketogenic diet.
Agar Seaweed
Raw agar seaweed contains approximately 6.3 grams of net carbohydrates per 100 grams. While this isn't exceptionally high, it may not be ideal for those strictly adhering to a keto diet. Consuming smaller portions can help manage carbohydrate intake, but it might not be the most efficient way to use daily carb allowance.
Carb Breakdown of Raw Agar Seaweed (per 100 grams):
- Total carbs: 6.8 grams
- Fiber: 0.5 grams
- Net carbs: 6.3 grams
A smaller serving of one ounce (28 grams) of raw agar seaweed contains:
- Total carbs: 1.9 grams
- Fiber: 0.1 grams
- Net carbs: 1.8 grams
Dried Agar Seaweed
The drying process significantly alters the nutritional profile of seaweed. Dried agar seaweed contains a much higher concentration of carbohydrates compared to its raw form.

Carb Breakdown of Dried Agar Seaweed (per 100 grams):
- Total carbs: 80.9 grams
- Fiber: 7.7 grams
- Net carbs: 73.2 grams
This substantial increase in net carbs makes dried agar seaweed less suitable for a keto diet. It's important to be mindful of the form in which seaweed is consumed.
Other Types of Seaweed
Seaweed encompasses a diverse range of species, each with unique nutritional compositions. Here's a comparison of net carb values per 100 grams for various types of seaweed:
- Spirulina: 2.4 grams
- Laver: 4.8 grams
- Agar: 6.3 grams
- Kelp: 8.3 grams
- Wakame: 8.6 grams
- Irish moss: 11 grams
Spirulina and laver seaweed have lower carbohydrate contents compared to others, making them more favorable choices for a keto diet.
Nutritional Benefits of Agar Seaweed
Beyond carbohydrate content, seaweed offers essential nutrients, including vitamins and minerals.
Nutrient Profile of Raw Agar Seaweed (per 100 grams):
- Calories: 26
- Protein: 0.5 grams
- Carbs: 6.8 grams
- Fiber: 0.5 grams
- Fat: 0 grams
- Folate: 21% of the Daily Value (DV)
- Manganese: 19% of the DV
- Magnesium: 17% of the DV
- Iron: 10% of the DV
- Potassium: 6% of the DV
- Other vitamins and minerals in smaller amounts
While agar seaweed provides valuable micronutrients, other low-carb foods offer similar benefits without the higher carb content.

Integrating Seaweed into a Keto Diet
Although some seaweeds are not particularly keto-friendly, they can still be included in moderation. Ketosis is a metabolic state where the body primarily burns fat for fuel, achieved by limiting carbohydrate intake.
General Guidelines for Ketosis
A typical ketogenic diet consists of:
- 55%-60% of calories from fat
- 30%-35% of calories from protein
- 5%-10% of calories from carbohydrates
This generally translates to a daily carbohydrate intake of 20 to 50 grams. Fiber is not included in this count.
Tips for Managing Seaweed Consumption on Keto
- Estimate Portions: Plan and measure the amount of seaweed you intend to consume.
- Avoid Mindless Eating: Be mindful of portion sizes, especially when snacking on dried seaweed.
- Track Intake: Monitor your carbohydrate intake to ensure you stay within your daily limits.
Is Nori Keto-Friendly?
Nori, a type of dried seaweed commonly used in sushi, has a relatively high carbohydrate content. A 100-gram serving of Nori contains approximately 46.79 grams of net carbs, which is nearly the entire daily carbohydrate allowance for many keto dieters. However, a single sheet of Nori (about 3 grams) contains only about 1.4 grams of net carbs.
Nutritional Profile of Nori (per 100g)
- Carbohydrates: 52.39g
- Protein: 31.84g
- Total Fats: 4.01g
- Vitamin A: 14.0ug
- Vitamin K1: 25.0ug
- Sodium: 575.0mg
- Potassium: 1244.0mg
- Magnesium: 482.0mg
- Calcium: 372.0mg
- Iron: 24.95mg
- Calories: 298 kcal
Alternatives to Nori
- Kelp: A sea vegetable with significantly lower carbohydrate content (9.57 grams of net carbs per 100 grams).
- Spinach: A low-carb leafy green (3.6 grams of net carbs per 100 grams) rich in vitamins and minerals.
- Cabbage: Another low-carb vegetable (5.8 grams of net carbs per 100 grams) that can be used in various dishes.
Wakame Seaweed and Keto
Raw wakame seaweed contains approximately 8.6 grams of net carbs per 100 grams, which can be incorporated into a keto diet in moderation.
