Dietary fibers have been closely studied for their health benefits and functional properties for the past three decades and fiber deficiency is well known to cause many nutrition-associated illnesses.
The European Food Safety Authority (EFSA) has recommended an average daily fiber intake of 25-38 grams (EFSA, 2010 European Food Safety Authority (EFSA) (2010). However, according to a study conducted in 2018, the average fiber intake in the GCC is only 13 grams per day – far below the recommended daily intake. Another study conducted in 2018 by the Emirates Gastroenterology and Hepatology Society (EGHS) in the UAE found that over 80% of the population in the country consumed less than the recommended daily intake of dietary fiber. This is a concerning trend, as fiber deficiencies have been linked to several health problems, such as obesity, diabetes, heart disease, hypercholesterolemia constipation, irritable bowel syndrome and colon cancer. Several studies have reported that the consumption of a high-fiber diet may prevent or reduce these ailments.
A wide range of functional and non-functional fibers offer food manufacturers the health benefits of fibers combined with their functional properties which can improve the texture of products and prevent syneresis (separation of water) due to fibers ability to hold water.
