Whole Food Papaya and Diabetes

Kyle J,Norton

People with Type II Diabetes may be thinking to add whole food papaya into their diet. the recent study suggested(1) ,
The finding not only showed the effectiveness of unripe pawpaw fruit (Carica papaya) in inhibition α-amylase, α-glucosidase, but also induced lipid peroxidation in a dose-dependent manner, in rat pancreas(1).
The key enzymes of α-amylase, α-glucosidase, involved in the digestion of carbohydrates, have been linked to onset of type 2 diabetes. Inhibition of these enzymes can significantly reduce the post-prandial increase of blood glucose and have been considered by therapists in use for management of blood glucose level in type 2 diabetic and borderline patients(2).

In streptozotocin-induced diabetic rats study, the aqueous extract of leaves of C. papaya administered strongly controlled blood glucose levels(3), through prevention of hepatocyte disruption, as well as accumulation of glycogen and lipids via its hypoglycemic and antioxidant effect(4)

Diabetes is defined as a condition caused by insufficient insulin entering the bloodstream to regulate the glucose. It is either caused by cells in pancreas dying off or receptor sites clogged up by fat and cholesterol. In some cases, diabetes is also caused by allergic reactions of cells in the immune system.

In a new study, conducted by the researchers at the Davis Heart and Lung Research Institute, fermented papaya preparation was tested whether it improves dermal wound healing outcomes in adult diabetic mice by preventing the  risk of infections(5).
The result was astonishing, the fermentation not only up regulated the Sp1 DNA binding activity(modulating the cellular response to DNA damage) in Peripheral blood mononuclear cells (PBMC) but also the protein and mRNA expression of Rac2(regulates a number of cellular functions)(5).

A randomized controlled clinical trial conducted at the Cardiac Centre, ANDI Centre of Excellence for Biomedical and Biomaterials Research and Department of Biosciences University of Mauritius, suggested that oral administration of 6g FPP®/day for a period of 14 weeks could improve the general health status of several organs targeted by oxidative stress during diabetes and suggested that the supplement may be used in the management the complications of diabetes such as cardiovascular disease, neurological disease and other conditions worsened by overt inflammation and oxidative stress(6).

Taken altogether, unripe, fermented papaya and its' leaves may be effective in diabetic management  through controlling the levels of glucose and  reduced risk of complications.

Some Western researchers insisted that large sample size and multi center studies are necessary to validate its effectiveness by identifying the ingredients which are comparable to recently pharmaceutical medicine in use because geography, environment, time of harvest, etc. may influence the concentration of the food cultivation.
 In fact, herbalists have longly acknowledged that the external factors (mentioned above) may alter the quality of the herbs and foods by classifying these difference either through price or formula differentiation. In deed, the effectiveness with little or no adverse side effects of the formula is not the concentration of individual herb and a herb itself but the interaction of all ingredients in a herb and herbs in the same formula. Extracting only one ingredient of the herb for treatment of certain diseases may be effective but enhanced complicative consequences. As always, all articles written by Kyle J.
