Kontraindizierte Eigenschaften und Nebenwirkungen von Seetang

Brown algae are considered to be one of the strongest natural sources of iodine. Some species of brown algae contain iodine in a concentration that is up to 30,000 times higher than in seawater. Iodine deficiency is becoming increasingly common worldwide and can lead to hypothyroidism and the formation of cysts. Due to its high iodine content, brown algae are often used as an aid in the treatment of thyroid problems. This element is necessary for the production of thyroid hormones, which regulate metabolic functions and the biosynthesis of hormones. Disorders in thyroid function, such as hypothyroidism, can lead to growth disorders and mental underdevelopment, as well as a slowed metabolic conversion. They may prevent or help treat diabetes. Brown algae can also be an ideal dietary supplement for diabetics or people at risk for this disease. A Korean study published in Nutrition Research and Practice found that the consumption of brown algae significantly improved blood sugar levels, glycemic control, and the activity of antioxidant enzymes in patients with type II diabetes. Blood clot reduction. Brown algae also have the ability to reduce blood clotting. Fucoidan (a polysaccharide) present in brown algae has been shown to be an effective means of preventing blood clots that can lead to dangerous health problems such as stroke and heart attack. It is so effective that scientists cite it as a potentially useful oral agent for preventing blood clots, potentially reducing the need for prescription drugs in the treatment of clotting problems. Cancer fighting. When it comes to cancer-fighting nutrients, fucoidan (found in brown algae) is one of the best-known polysaccharides. Studies have shown that it induces programmed cell death in cancer cells. This is especially true for leukemia, colon, breast, and lung cancer. It also has anti-inflammatory properties, which positively affects the immune system and protects the body from chronic diseases. Bone strengthening. Brown algae can also be beneficial for people at risk of osteoporosis. They are a rich source of vitamin K, which strengthens the bone system. It has also been shown that fucoidan can help prevent age-related bone loss and improve bone mineral density. However, it is important to note that people taking blood-thinning medications should avoid additional vitamin K, as it can interfere with the effectiveness of the medication.

Cautions regarding the use of kelp are primarily directed towards women who are pregnant or breastfeeding. This rule applies to most medicines and dietary supplements. During pregnancy and breastfeeding, extra caution should be exercised, and no medicines that may have an effect on the body should be taken without consulting a doctor beforehand.

Occasionally, individuals who consume kelp encounter adverse reactions such as irritations, vomiting, and hair loss. However, these symptoms are transient and disappear after reducing the kelp dosage. Simultaneously taking kelp and zinc may also be advisable. Exceeding the recommended dosage can also result in arsenic poisoning. This element is naturally present in kelps, but it is essential in the appropriate concentrations in the diet, in case of consumption in excess, it can be toxic. It is crucial to know that kelp is an excellent source of iodine and can be incorporated into the diet in cases of iodine deficiency, but only in a dose that matches the body's needs. In case of worsening symptoms or any uncertainties concerning kelp intake, a doctor should be consulted. There are about 30 different types of seaweeds that grow in cold waters worldwide, some of which are the best available sources of iodine. Kelp can aid in weight loss, improve diabetes risk factors, and prevent blood clots, while the contained fucoidan displays anticancer anti-inflammatory properties. However, it is vital to consult a doctor before supplementing with seaweeds to avoid an excess of iodine in the diet, which can also be detrimental to health.
