Seaweed: Weightoss Help From the Ocean
taken daily before meals, helped people
in a new
study funded by a Danish Company. The supplement is based on the
alginate, a thickening agent and a common ingredient in foods like
soups and jellies.
Seaweed is a wonder crop, with notable health benefits. For ages, the Asians
have eaten foods wrapped in dried seaweed. The most popular edible seaweeds
include deep green kombu, dried black hijiki, chewy red dulse, emerald wakame,
bright, leafy sea lettuce, and dark, toasted nori.
Since seaweeds grows in the ocean, they contain
essential amino acids, certain
minerals that aren't as available in land-grown vegetables. This extra
variety makes seaweed a good food to mix into your diet. They contain
(beta carotene) and
C. Seaweeds are rich in
magnesium because these minerals are concentrated in sea water. They are
also one of the few vegetable sources of
Seaweed & Weight loss:
12-week double-blind study, appeared in the American Journal of Clinical
Nutrition, was completed by 80 obese individuals who were divided into two
groups. Both groups consumed a calorie-restricted diet, but one group also
consumed a placebo beverage three times daily before each meal while the other
group consumed a beverage that contained the seaweed-based supplement.
At the end of 12 weeks, participants in the placebo group had lost an
average of 5.04 kg (11.11 lb) while those in the seaweed supplement group lost
an average of 6.78 kg (14.95 lb), for a difference of nearly 4 additional pounds
lost in the seaweed group.
The seaweeds used in the supplement were Laminaria hyperborea and L.
digitata. Both are species of a large brown alga and are found in the northern
Atlantic Ocean. These brown alga contain a natural fiber called alginate, which
is often used as a thickener and stabilizer in foods. Alginate has been shown to
significantly reduce the amount of fat the body absorbs.

The Victoria Secret Model, Miranda Kerr banks on
sea weed supplement. In the words of Miranda Kerr, "I like to start my day
with a fresh pressed green juice with kale, cucumber, spinach, parsley and
lemon. Half an hour later I like to make a smoothie with sun warrior protein
powder, goggi berries, noni juice, viatmineral greens, chia seeds, bee
pollen, raw cacao powder, macca powder and acai powder. I will then have
organic eggs or oatmeal for breakfast. That works for me and is a great way
to get my body started for the day. I believe breakfast is one of the most
important meals in the day."
Other Benefits of
Acid Booster: Nori, a type of seaweed is composed of 30 to 50 percent
protein. Most of the protein comes from the amino acids alanine, glutamic and
glycine, which are also responsible for this seaweed's distinctive flavor. Kombu
contains approximately 10 percent protein.
Broadest range of minerals: Are an excellent source of the
magnesium, as well as a great source of iron, calcium, and the
B-vitamins riboflavin and pantothenic acid. Brown seaweeds, such as kombu
and hijiki, also contain iodine. Dulse is high in iron and also contains all
the essential trace minerals known to be necessary in human nutrition.
Anti-cancerous: Seaweed contains significant amounts of lignans,
which are plant compounds with cancer-protective properties. Lignans have
been shown to inhibit angiogenesis, or blood cell growth, the process
through which fast-growing tumors not only gain extra nourishment, but send
cancer cells out in the bloodstream to establish secondary tumors or
metastases in other areas of the body. In addition, lignans have been
credited with inhibiting estrogen synthesis in fat cells as effectively as
some of the drugs used in cancer chemotherapy. In postmenopausal women, fat
tissue is a primary site where
estrogen is synthesized, and high levels of certain estrogen metabolites
are considered a significant risk factor for breast cancer.
Thyroid Health: The RDA of iodine is 150mcg for most adults.
Large percentage of which comes from iodized salt, but as more people reduce
the sodium in their diets, deficiencies could occur. That's one important
reason why seaweed is a great dietary addition — it's one of the best food
sources of iodine. Regularly including a variety of sea vegetables in your
diet can help keep your thyroid working properly. An under-active thyroid
can lead to weight gain, fatigue, cold sensitivity,
loss of hair and slow pulse.
Anti-aging & Anti-cellulite skincare: It can detoxify and
cleanse, tone the
skin, naturally smoothen and
moisturize the skin. It has been known for a long time that seaweed is
an emollient with smoothing, tissue renewal and anti-inflammatory properties
that can have a positive effect on problems such as facial
It acts as a moisturizer by its hydrating and protective action of forming a
layer on the skin that reduces loss of skin moisture through evaporation.
Essential Fatty Acids that are contained in Seaweed are a part of the lipid
layer in your skin, and help maintain the suppleness and elasticity of skin.
Wound Healing: Seaweed Alginate is used as a dressing for
severe burns/wounds. The oils in seaweed have long been used to recuperate
from illness, by detoxifying the body and helping the renewal of damaged
skin cells. Seaweed was known as “Sailor's Cure” by ancient mariners.
Reduced Cell Damage: Seaweeds contain Algal polyphenols &
Carotenoids which have been proven to be powerful antioxidants. Antioxidants
are compounds that protect against cell damage inflicted by molecules called
oxygen-free radicals, which are a major cause of disease and aging. Like
beta carotene and vitamins C and E, polyphenols protects the cells in your
body from an unstable form of oxygen called a free radical. The antioxidant
combines with the free radical to prevent it from attaching to and damaging
the cells in your body.
Reduced Birth Defects: Folic acid is abundant in sea vegetables
and plays a number of other very important protective roles. Studies have
demonstrated that adequate levels of folic acid in the diet is needed to
prevent certain birth defects, including spina bifida.
The easiest way to eat seaweed is by using dried seaweed wrapper, the kind
you find served in sushi restaurants. You can find packs of these wrappers
(called "nori") in most grocery stores.
