Adding seaweed to processed foods such as frozen pizzas, hot dogs and dried pasta will reduce cardiovascular diseases, concludes a new scientific article in the journal Phycologia co-authored by University of Southern Denmark professor of biophysics, Ole G. Mouritsen. One suggestion is to replace 5% of the flour in pizza dough with dried and granulated seaweed.In the article the authors offer suggestions as to how both individual consumers and the food industry can use seaweed to make 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,” said Mouritsen.Many seaweed species have a variety of health benefits, Mouritsen says. They contain, among other things, beneficial proteins, antioxidants, minerals, trace elements, dietary fibre and polyunsaturated fatty acids, while seaweed’s content of potassium salts does not led to high blood pressure - unlike the sodium salts, typically encountered in 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,” said Mouritsen. He and the co-authors suggest that seaweed should be added to fast food, thus making this type of food healthier. It can even enhance the flavour 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.It is also possible to add seaweed to meat products and thereby provide the consumer with an increased intake of dietary fibre 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 fibre (4.5 g more fibre 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 said.
