Dietitian's Tips for Consuming Seaweed

Metabolic Impact: Agar is particularly rich in soluble fiber, which slows digestion and prolongs satiety after meals. It helps moderate post-meal blood sugar spikes by forming a gel-like substance in the gut that buffers glucose absorption.
Consumption Suggestion: Adding 5–10 grams of dry agar daily, alongside adequate fluid intake, is a practical way to support regular bowel movements. You can stir it into soups, desserts, or smoothies as a gelling agent to quietly work toward your daily fiber goals.
Things to Watch Out For: Consuming dry agar without sufficient water can cause bloating and gastrointestinal discomfort, so always pair it with plenty of fluids. People with thyroid conditions should be mindful of the iodine content in seaweed-derived products and consult their doctor before regular use.
Exercise Equivalent: The 26 calories in 100 grams of agar can be burned off with just 4–5 minutes of brisk walking. Its low caloric density makes it a worry-free addition to pre- or post-workout meals without meaningfully affecting your energy budget.
