Pectin and Its Beneficial Effect on Health: New Contributions in Research and the Need to Increase Fruits and Vegetables Consumption-A Review

The beneficial effect of consuming fruits and vegetables in the prevention of chronic non-communicable diseases and healthy aging is well known. This is attributed to food and vegetable antioxidant and fiber content. The aim of this publication is to communicate the results of recent research on pectin in humans, to propose an increased consumption of fruits and vegetables, or their possible use as a food supplement. A comprehensive narrative review was conducted considering recent publications on pectin. The description of starch, pectin, the physicochemical changes caused by pectin, and the effect of pectin on the activity of amylase are reported. Dietary fiber and gut microbiota in human health are also described, with the production of saturated fatty acids with fewer than six carbon atoms. Finally, health effects such as anti-hyperglycemic and anti-hyperlipidemic activities, preventing and controlling obesity and heart disease, are analyzed, as well as other health effects in tumors, the gastrointestinal tract, and immunity. Considering the beneficial effects of pectin in health and the low consumption throughout the world, it is recommended to promote the consumption of fruits and vegetables to increase pectin intake in the human diet.
