A Tropical Fruit Which Processes Anti Type II Diabetes Potency, Scientists Found

By Kyle J. Norton

Papaya may be used as function food to inhibit early onset and treatment of diabetes, some scientists suggested.

Diabetes is a medical and chronic condition characterized by abnormally high levels of sugar (glucose) in the blood caused by pancreas inability in produced insulin.

In other words, diabetes is a result of absence or insufficient production of insulin by pancreas. The condition is also caused by the inability of the body to properly use of insulin, leading to insulin resistance.

According to the statistic produced by the Canadian diabetes Association, approximately, 17%
of Canadian over 12 years of age are diagnosed with diabetes.

Interestingly, diabetes affects both genders up to age 64. The prevalence does not increase significantly for those aged 65 and older.

Unlike type 1 diabetes which is caused by the immune system attacking the cells in the pancreas that make insulin, leading to the body without enough insulin to function normally, type 2 diabetes is caused by unhealthy diet and life style.
 

Obesity and increasing age are 2 of many risk factors that can elevate risk of type 2 diabetes. 

Symptoms of type 1 and 2 diabetes, according to Medicine Net include increased urine output, excessive thirst, weight loss, hunger, fatigue, skin problems slow healing wounds, yeast infections,….. and tingling or numbness in the feet or toes(6).

If you experience some of above symptoms, please see doctor to rule out the possibility.

Papaya is a species of Carica Papaya, belongings to the family Caricaceae and native to the tropics of the Americas, and was first cultivated in Mexico and several centuries

Chemical constituents
Alkaloids, Cardenolides, Anthraquinones, Saponins, Tannin, phenol, flavonoid, anthocyanin, Benzyl glucosinolate, benzylisothiocyanate, 5-(Hydroxymethyl)-2-furancarboxaldehyde, 2,3-dihydro-3,5-dihydroxy-6-methyl-4H-pyran-4-one and 1,3-dihydroxy-2-propanone, etc.(a).

Water extract from papaya isolated from unripe pawpaw (Carica papaya Linn) fruit, exerted a significant effect in inhibition of enzymes, α-amylase and α-glucosidase that linked to type 2 diabetes, in sodium nitroprusside (SNP)-induced lipid peroxidation mice model and a dose-dependent manner(1).

Combination of the flesh, seed and peel in equal amounts produced the highest inhibitory effect on α-amylase  and α-glucosidase activities in compared to other preparations.

Dr. Oboh G, the lead authors in the study said, “Strong inhibitory activities of the unripe pawpaw fruit against key enzymes linked to type 2 diabetes and SNP-induced lipid peroxidation in rat pancreas could be part of the mechanism by which unripe pawpaw is used in themanagement/prevention of diabetes mellitus in folk medicine”(1).

Truly, in the preparation of individual aqueous extract of the unripe pawpaw fruit parts; peel (PG), seed (SG), flesh (FG), flesh with peel (FPG) and a combination of equal amount of all parts (CG), the Federal University of Technology at the end of experiment indicated that on Fe²⁺-induced lipid peroxidation in rat pancreas, application of the prepared extracts phenolic compounds inhibited oxidative stress through their antioxidant activities(2). 

According to Universidad Juárez Autónoma de Tabasco (UJAT), unripe papaya preparations not only exert hypoglycemic effects in both animals and humans studies, but also help islet regeneration,  preservation of cell size and prevented hepatocyte disruption(3).

In fact, the aqueous extract of Carica papaya also significantly decreased blood glucose levels in diabetic rats and decreased cholesterol, triacylglycerol and amino-transferases blood levels without changing the levels of plasma insulin levels in diabetic rats(4).

 In short term supplementation of a fermented papaya, showed to exhibit its effect in management of diabetes and for those at risk for cardiovascular disease, neurological disease and other conditions worsened by overt inflammation and oxidative stress(5).

These findings suggested that all parts of unripe papaya have a strong and profound effect in inhibition of diabetic onset and treatment of type 2 diabetes.

However, a large sample size and multi centers clinical trial on human consumption on the course of the disease onset are necessary to confirm the unripe papaya anti diabetes possibility.
