Health benefits

The main health benefits of wakame are:

1. Promoting weight loss

Wakame helps to increase satiety and reduce food consumption, due to the amount of fiber it contains, forming a gel in the stomach and delaying gastric emptying, promoting weight loss. Furthermore, because it is low in calories and rich in protein, wakame is a food that can be incorporated into weight loss diets.

However, for wakame to help with weight loss, it is important that it is part of a healthy, balanced diet, along with regular physical activity. See ARTICLE NOT FOUND IN EN: how to follow a healthy diet to lose weight.

2. Preventing premature aging

Wakame is rich in antioxidants such as vitamin C, vitamin E and beta-carotene, nutrients and bioactive compounds that fight excess free radicals in the body, preventing damage to healthy cells in the body and thus preventing premature aging of the skin.

3. Maintaining brain health

Wakame is rich in antioxidant compounds and choline, a nutrient that is a precursor to acetylcholine, an important neurotransmitter that helps improve memory and facilitate learning, preventing cognitive problems and neurodegenerative diseases such as Alzheimer's and Parkinson's.

4. Helping to lower LDL cholesterol

Wakame has antioxidant properties that help reduce "bad" cholesterol, LDL, as well as reducing the absorption of cholesterol in the intestine due to the presence of fiber, preventing the development of cardiovascular diseases, such as atherosclerosis, heart attack and stroke.

5. Improving thyroid function

Wakame is rich in iodine, an important hormone for the production of thyroid hormones necessary for growth, metabolism, protein synthesis and cell repair, preventing problems such as weight gain, excessive fatigue, dry skin and hair loss.

How to eat

Wakame is safe for consumption when eaten in moderate amounts. Although there is no specific amount of wakame you can eat per day,  one scientific study indicates that one should not ingest more than 10 to 20 grams of seaweed per day to avoid exceeding the recommended daily dose of iodine.

One way to reduce the iodine content in this seaweed is to consume wakame with foods that contain substances that reduce iodine absorption in the thyroid, like broccoli, cabbage, bok-choy and soybeans.

Contraindications

Due to its high iodine content, Wakame should not be consumed by anyone with a history of thyroid disease, especially hyperthyroidism, as it can impair the production of thyroid hormones and aggravate the disease.

Pregnant women and children should also limit their intake of wakame.
