A new scientific article concludes that adding seaweed to processed foods such as frozen pizzas, hot dogs and dried pasta will reduce cardiovascular diseases. One suggestion is to replace 5% of the flour in pizza dough with dried and granulated seaweed.
According to the World Health Organization (WHO) cardiovascular diseases are the number one cause of premature death globally. Ironically, many of the pathologies leading to premature death from cardiovascular diseases are not only widespread, but they are preventable.
‘Many seaweed species have a variety of health benefits and an important feature is also that the seaweed has umami - the fifth basic taste, which is known to promote satiety and hence regulate food intake.’
AdvertisementOne way to prevent cardiovascular diseases is to avoid obesity and eat healthy, leaving the responsibility with the individual consumer. But the responsibility should also be shared by society, argues University of Southern Denmark professor of biophysics, Ole G. Mouritsen, who has authored several books on seaweed as food.
Professor Mouritsen is the co-author of an article in the journal Phycologia reviewing existing knowledge on the health effects of 35 different seaweed species. In the article the authors offer suggestions to how both individual consumers and the food industry can use seaweed to make our everyday meals healthier.
"Certain substances in seaweed may be important for reducing cardiovascular diseases. We think this knowledge should be available for society and also be put to use", says Mouritsen.
Seaweed salt is healthier salt
Many seaweed species have a variety of health benefits. They contain, among other things, beneficial proteins, antioxidants, minerals, trace elements, dietary fiber and polyunsaturated fatty acids.
Seaweed's content of potassium salts does not led to high blood pressure - unlike the sodium salts, typically encountered in the processed food.
An important feature is also that the seaweed has umami - the fifth basic taste, which is known to promote satiety and hence regulate food intake in addition to reduce the craving for salt, sugar and fat.
"It is difficult to determine how much seaweed a person should consume to benefit from its good qualities. 5-10 grams of dried seaweed per day is my estimate", says Professor Mouritsen.
He and the co-authors suggest that seaweed should be added fast food, thus making this type of food healthier. It can even enhance the flavor of the food, they argue. For example, dried and granulated seaweed can replace some of the flour when producing dry pasta, bread, pizza, snack bars, etc.
Seaweed is also good in meat products
It is also possible to add seaweed to meat products and thereby provide the consumer with an increased intake of dietary fiber and antioxidants - or maybe the aim is lower cholesterol levels.
In the article Professor Mouritsen and his co-authors describe a study in which a group of overweight but otherwise healthy men were asked to taste bread with added dried seaweed from the species Ascophyllum nosodum. The men's reaction was that the bread tasted acceptable as long as the seaweed content was kept under 4%.
By eating bread containing 4% of dried seaweed the overweight men ingested more dietary fiber (4.5 g more fiber per. 100 g) than when they ate the control whole-meal bread. Another effect was that they consumed 16.4% less energy in the 24 hour period after eating the seaweed enriched bread.
"We know that many people have difficulty distinguishing between healthy and unhealthy food. By adding seaweed to processed foods we can make food healthier. In many cases we also get tastier food, and it may also help reduce the risk of cardiovascular diseases", the authors believe.
HOW TO GET THE HEALTH BENEFITS FROM SEAWEED
- Seaweed contains only few calories, but is still rich in rich in essential amino acids, dietary fibers, minerals, trace elements, vitamins and polyunsaturated fats.
- You can easily add up to 5% dried seaweed to a dough without losing its ability to raise.
- Dried seaweed can be stored for months or years without loss of flavor and nutritional value.
- Dried seaweed can be added to food as powder, granulate or pieces in pastries, egg dishes, mashed potatoes, dressings, or sprinkled on vegetables or fish dishes.
- Powders and granulates can be used as a salt substitute.
- Hijiki contains arsenic, which is carcinogenic and therefore some national food authorities recommend that you do not eat it. Despite these warnings, you can buy dried hijiki in many stores.
- Some species may contain large amounts of iodine.
- Never eat seaweed that is washed up on the beach.
