Definition:Fucoxanthin is a carotenoid, with formula C42H58O6. It is found as an accessory pigment in the chloroplasts of brown algae and most other heterokonts, giving them a brown or olive-green color. Fucoxanthin absorbs light primarily in the blue-green to yellow-green part of the visible spectrum, peaking at around 510-525 nm by various estimates and absorbing significantly in the range of 450 to 540 nm. Some metabolic and nutritional studies carried at Hokkaido University indicate that fucoxanthin promotes fat burning within fat cells in white adipose tissue by increasing the expression of thermogeniIt is a type of carotenoid found naturally in edible brown seaweed such as wakame (Undaria pinnatifida) and hijiki (Hijikia fusiformis), which are used widely in Asian cuisine. Wakame is the seaweed used in miso soup….CLICK & SEE THE PICTURES

Fucoxanthin is also found in much smaller amounts in red seaweed (the kind typically used in Japanese sushi rolls) and green seaweed.

Both wakame and hijiki are available at Japanese specialty food stores, some health food stores and online. Although brown seaweed is the richest source of fucoxanthin, you would have to eat an unrealistic amount of it daily to get fucoxanthin levels close to those used in research studies.

Fucoxanthin is also available as a nutritional supplement in capsule form and can be found in some health food stores and online.

Medicinal Uses:

Weight Loss
Fucoxanthin is being explored for weight loss. So far, only animal studies have been done. Japanese researchers have found that fucoxanthin (isolated from wakame) promotes the loss of abdominal fat in obese mice and rats. Animals lost five to 10% of their body weight.

Although it’s not fully understood how fucoxanthin works, it appears to target a protein called UCP1 that increases the rate at which abdominal fat is burned. Abdominal fat, also called white adipose tissue, is the kind of fat that surrounds our organs and is linked to heart disease and diabetes. Fucoxanthin also appears to stimulate the production of DHA, one of the omega-3 fatty acids found in fatty fish such as salmon.

Although it’s promising and already a popular nutritional supplement, more research is needed to determine if fucoxanthin will work in the same way in humans. If it does prove to be effective, fucoxanthin could be developed into a diet pill for obesity.

Fucoxanthin has also been found in animal studies to decrease insulin and blood glucose levels. Researchers hypothesize that fucoxanthin anti-diabetes effect may be because fucoxanthin appears to promote the formation of DHA (the omega-3 fatty acid found in fish oil). DHA is thought to increase insulin sensitivity, improve triglycerides and reduce LDL (“bad”) cholesterol.

Preliminary research in test tubes suggests that fucoxanthin may have anti-tumor effects. No studies have looked at whether this holds true in humans or if taken orally. It’s far too early for fucoxanthin to be used as a complementary treatment for cancer.

Side Effects
Because there hasn’t been research on fucoxanthin in humans, the possible side effects aren’t known.

People shouldn’t consume large amounts of wakame or other types of seaweed as a source of fucoxanthin. Seaweed is rich in iodine and excessive consumption may result in iodine poisoning. High levels of iodine can interfere with the function of the thyroid gland. Also, consuming excess amounts of iodine-rich foods isn’t recommended if there is a known allergy or hypersensitivity to iodine.



Omega-3 fatty acids For Heart Disease

Learn the numerous benefits of fish oil for good cardiovascular health.
Consider, for a moment, the Eskimos of Alaska and their indigenous cousins in Canada and Russia. These hardy souls survive on diets of nearly pure fat, and yet they tend to be completely free of heart disease. How in the world is this possible? The answer is fish oil….click & see

Every medical journal on heart health brings, it seems, another study demonstrating the cardiovascular benefits of the oil — specifically, its omega-3 fatty acids, a type of polyunsaturated fat found in few foods other than fish and flaxseed. A primary reason it’s so healthy: omega-3s are a natural anti-inflammatory. In recent years, scientists have discovered that inflammation within our arteries — triggered in response to damage done by plaque, high blood pressure, and free radicals — is a major cause of heart disease. While inflammation is a healing response, in your blood vessels it only causes further damage, leaving them stiffer and working at far less then optimal capacity. Omega-3s cause this type of inflammation to recede.

There’s more. Omega-3 fatty acids also seem to make blood less sticky so it’s less likely to form clots that can block blood flow and trigger a heart attack. They also seem to affect heart rhythm, keeping it more regular and reducing your risk of sudden death caused by arrhythmia, or erratic heartbeat, a major cause of death from coronary artery disease. And they lower levels of triglycerides, blood fats linked with heart disease.

Bottom line: Get more omega-3 fatty acids into your body, either through foods or supplements. Plus, here are the fish with the largest amounts of this crucial nutrient (amounts are per 3.5 ounces of fish):

Mackerel: 2.6 grams

Atlantic herring: 1.7 grams

Chinook salmon: 1.5 grams

Fresh albacore tuna: 1.5 grams

Anchovies: 1.4 grams
