One of the richest forms of plant life, seaweed (Ascopyllum Nodosum) is abundant in health-promoting properties, and as such forms an essential part of any canine diet. The study also noted additional improvements in blood sugar levels in those with a genetic disposition to insulin resistance, which usually accompanies type 2 diabetes ( 51). This poses a health risk, as seaweed can also contain large amounts of toxic heavy metals such as cadmium, mercury, and lead.

Nevertheless, seaweed contains a wide variety of plant compounds that work together to have strong antioxidant effects ( 26). SummaryYour thyroid gland releases hormones to help control growth, energy production, reproduction and the repair of damaged cells in your body ( 1, 2). There are more than 100 different species of edible seaweed, and around 10,000 species of macro-algae. Seaweed comes in three color varieties – red, brown and green. Brown varieties of seaweed are the most commonly eaten, including wakame and kelp. They are also the varieties that have had the most scientific research conducted on them. The next most common is red seaweed, such as nori, which is the one you would be familiar with if you frequent sushi restaurants. Unsurprisingly, the most common seaweed-based diets are eaten in Japan, which is where sushi originates, and Japanese diets are among the healthiest in the world. Health Benefits Of Seaweed Japanese people’s high seaweed intake might be one reason why they have the highest life expectancy in the world ( 57). While seaweed can definitely be considered a superfood for its extraordinary health benefits, there are potential health issues to consider before adding it to every meal. Dulse, a type of red seaweed, for example, has more than 30 times the amount of potassium than an equally sized piece of banana. Eating that much potassium runs the risk of causing heart palpitations in people with kidney problems, however, it doesn’t pose a threat in people without pre-existing problems. Dried or processed seaweed products can be used much as you would any other plant tonic, when the plants are actively growing (usually between March and September). These products are available in liquid or solid form, so always read the label to find out the best way of application.

DIY Revitalizing Seaweed Mask – This vitamin and mineral-rich mask will tone and moisturize the skin, soothe any inflammation, unclog pores and help remove toxins from the body. All you need is kelp powder, which is readily available at most health food stores, aloe vera gel, and distilled water. Seaweed is an umbrella term for plants and algae that grow in all bodies of water. Some different types of seaweed that are beneficial for skin include red algae, kelp, giant kelp, sea spaghetti, carrageenan, and brown seaweed. While a few case reports have associated iodine-containing kelp consumption and thyroid dysfunction, thyroid function returned to regular once consumption stopped ( 58, 59). While it may only contribute to a small percentage of some of the DVs above, using it as a seasoning once or twice per week can be an easy way to add more nutrients to your diet.Seaweed also contains fatty acids to soothe skin irritation and inflammation and may help with skin ailments such as acne, psoriasis and eczema. Although seaweed is considered a healthy food, there may be some potential dangers to consuming too much. Excess Iodine If you do have access to fresh seaweed, it is a useful substitute for farmyard manure, and does not need to be rotted down before use. It is best dug in fresh in winter or spring before it has had time to dry.

A recent study analyzed the concentration of 20 metals in 8 different seaweeds from Asia and Europe. It found that the levels of cadmium, aluminum, and lead in 4 grams of each seaweed did not pose any serious health risks ( 62). The results showed that fucoxanthin increased the expression of a protein that metabolizes fat in rats ( 36). Dried seaweed that is not a powder can be used in soap-making in at least two ways. You could also use whole, or chopped, dried seaweed as a botanical decoration for the top. I’d advise this only if you live in an area without high humidity, though.
