Net Carb Calculator for seaweed
To calculate the net carbs in seaweed, you need to subtract the fiber content from the total carb content. Here’s how:
Net Carbs = Total Carbs – Fiber
For example, if a serving of seaweed contains 5 grams of total carbs and 3 grams of fiber, the net carbs would be:
Net Carbs = 5 grams – 3 grams
Net Carbs = 2 grams
So in this example, a serving of seaweed would contain 2 grams of net carbs. Keep in mind that the carb and fiber content of seaweed can vary depending on the type and the serving size, so it’s always a good idea to check the nutrition label to be sure.
