The Health Benefits of Red Algae




Seaweed has been part of the human diet for hundreds of years. Especially for those living in the coastal areas, seaweed has either been a staple, food additive or delicacy. One of the most-eaten types of seaweeds is red algae, which is traditionally used in Asian and European cuisines. To date, there are about 6000 species of red algae found in many tropical and subtropical regions.

The red algae derive their colour from the red pigments – called
phycoerythrin and phycocyanin – which mask the green pigments. The red pigments also allow photosynthesis in areas of the sea where sunlight can barely penetrate. This is why many of the red algae can be found deeper in the seabed where green or blue-green algae are rarely found.
 
But while red algae are consumed mainly because of its wide availability and unique flavour, it also has its health benefits.

Rich source of antioxidants
 
Red algae are packed with antioxidants including vitamins A and E and manganese which can fight against free radical damage in our bodies. If these free radicals damage our cells, it can result in certain diseases including cancer, heart failure and Alzheimer’s disease. 500 grams of red algae contains about 325 micrograms of vitamin A, 0.5 mg of vitamin E and 8.15 mg of manganese.

Strengthens immunity
 
Most species of red algae contain carrageenans, a type of carbohydrate that is gelatinous and commonly used in the food industry for its binding property. When red algae are consumed, the carrageenans promote the production of interferons in our system. Interferons are proteins released by the body to fight against viruses that cause illnesses. Through the increased production of interferons, the body develops an improved response against pathogens and disease-causing agents.

Vitamin and Mineral-rich food source
 
Red algae are also a rich source of other nutrients that are essential for our overall wellbeing. Specifically, it provides the minerals sodium, calcium, iron, zinc, copper, phosphorus and potassium. It also contains a range of B vitamins, such as B1, B2, niacin (B3) and folate (B9). Additionally, it’s interesting to know that with 1 cup serving of red algae, you only get 27 calories and less than 0.1 grams of fat.

Other Health Benefits
 
Aside from being used as a food ingredient, red algae are also cultivated to be used in the pharmaceutical industry as a supplement. These supplements are known to support healthy ageing, such as promoting heart health, eye health, joint health and memory function.
