Blue-Green Algae – Breakthrough For Diabetes And Heart Disease

| January 19, 2016

The mention of algae might make you think of the slimy stuff that coats the sides of fish tanks and swimming pools and turns the water green. But annoying as they may be when they grow where we don’t want them to, algae are actually a real health-boosting superfood. And they have special benefits for people with diabetes.

In particular, algae can help to stabilise blood sugar levels and improve cardiovascular health. The three kinds that have been most studied, and have been found to have the greatest benefits, are all blue-green ones – chlorella, spirulina and Klamath Lake algae.

These edible algae are among the most nutrient-dense foods on the planet. They contain around 70 per cent protein – more than a beef steak – and are chock-full of vitamins, minerals and other important nutrients. And all of that nutritional goodness is in a form that is easily and efficiently digested and absorbed by the body.

Studies have found that chlorella has antidiabetic effects. For instance, when rats that had been made type 2 diabetic by a high-fructose diet were given chlorella (three times daily for five days), their insulin resistance was reversed.1 And even a single dose of chlorella reduced blood sugar levels in these rats.

Other researchers have shown that chlorella can block the action of enzymes that break down starches into glucose and promote its absorption into the blood stream.2 This means that chlorella could help to prevent blood sugar peaks after meals.

In human clinical trials, chlorella has shown an ability to reduce stiffness in the arteries, lower blood pressure and improve cholesterol and blood fat readings, so reducing the risks of a heart attack or stroke.

The type of chlorella that has been most studied for its antidiabetic and heart health effects is Chlorella pyrenoidosa, so this is the one to look for in supplements. You may need to take five or six grams of chlorella a day to see beneficial effects, so it is a good idea to buy it in 500 mg size tablets.

In my next blog post I’ll tell you about spirulina and Klamath Lake algae, two more blue-green algae with amazing health benefits.

Wishing you the best of health,
