Health Benefits
Boosts thyroid healthMost seaweeds are a rich source of iodine, which the thyroid gland needs to produce the hormones that regulate body metabolism
Helps build muscles
A ½-cup (113-g)serving of raw nori has a mere 40 calories yet provides about 6 g of protein, with no fat or cholesterol
Boosts the immune system
Beta-carotene, a precursor of vitamin A, boosts the body’s resistance to disease while aiding vision, bone growth, and cell function
A ½-cup serving of raw nori provides 5,200 IU of vitamin A as beta-carotene
Prevents folate deficiency
A ½-cup serving of kelp contains almost 200 mcg (micrograms) of folate (50% of the adult Recommended Dietary Allowance) which the body uses as folic acid to build DNA and red blood cells
Because folate is not stored in the body in large amounts, you must eat it regularly to maintain levels of it in the blood
Health Risk High in sodium
A ½-cup portion of raw wakame contains approximately 900 mg of sodium; an equivalent amount of dried spirulina yields more than 1,100 mg
(A recommended daily sodium intake for a healthy person should not exceed 2,300 mg
) The same amounts of kelp and nori are lower in sodium, containing 250 mg and 60 mg, respectively
Anyone on a low-salt diet should avoid foods containing seaweed
