Durian, like other tropical fruits such as Banana, avocado, and jackfruit, is rich in energy, minerals and vitamins. 100 g fresh fruit provides 147 calories.
The fruit is made of soft, easily digestible flesh made of simple sugars like fructose and sucrose that when eaten replenish energy and revitalize the body instantly. Though it contains a relatively high amount of fats among fruits, it is free from saturated fats and cholesterol.
Durian is rich in dietary fiber, which makes it a good bulk laxative. The fiber content helps to protect the colon mucous membrane by decreasing exposure time and as well as binding to cancer-causing chemicals in the colon.
The durian fruit is a good source of antioxidant vitamin-C (about 33% of RDA). Consumption of foods rich in vitamin C helps the body develop resistance against infectious agents and scavenge harmful free radicals.
The fruit is an excellent source of health benefiting B-complex groups of vitamins; a rare feature among fruits, such as niacin, riboflavin, pantothenic acid (vitamin B5), pyridoxine (vitamin B-6) and thiamin (vitamin B-1). These vitamins are essential for the body as it requires them from external sources to replenish.
Further, it also contains a good amount of minerals like manganese, copper, iron and magnesium. Manganese is used by the body as a co-factor for the antioxidant enzyme, superoxide dismutase. Copper is required in the production of red blood cells. Iron is required for red blood cell formation.
Fresh durian fruit is a very rich source of potassium. Potassium is an important electrolyte of cell and body fluids that helps controlling heart rate and blood pressure.
Additionally, it also contains high levels of essential amino acid, tryptophan (also known as "nature's sleeping pill") which in the body metabolizes into serotonin and melatonin; these neuro-chemicals have important functions like sleep induction and in the treatment of epilepsy.
