3. Types of Diabetes – A Quick Overview
To understand how karela helps, it’s important to differentiate between the types of diabetes:
Type 1 Diabetes: An autoimmune condition where the body produces little or no insulin.
Type 2 Diabetes: A metabolic disorder where the body becomes resistant to insulin or doesn’t produce enough.
Gestational Diabetes: Develops during pregnancy and usually resolves after childbirth.
Karela juice is particularly beneficial for Type 2 Diabetes and gestational diabetes due to its ability to regulate blood sugar levels naturally.
4. Why Karela Juice is Beneficial for Diabetics
a. Lowers Blood Sugar Levels
Karela juice contains charantin, which has been shown to reduce blood glucose levels in both fasting and postprandial (after-meal) states.
b. Improves Insulin Sensitivity
Compounds like polypeptide-p mimic insulin and help the body utilize glucose more effectively, reducing the need for artificial insulin.
c. Stimulates Pancreatic Function
Karela may stimulate the beta cells of the pancreas to produce more insulin, especially in people with Type 2 diabetes.
d. Reduces Sugar Absorption
Karela slows down the absorption of glucose in the intestines, thus preventing sudden spikes in blood sugar.
e. Rich in Antioxidants
Oxidative stress is a major contributor to diabetic complications. The antioxidants in karela help neutralize free radicals and protect organs.
5. Scientific Evidence Behind Karela and Diabetes
Numerous studies support the use of bitter gourd for managing diabetes:
- Journal of Ethnopharmacology (2004): Found that karela extracts significantly lowered blood glucose in both humans and animals.
- Asian Pacific Journal of Tropical Disease (2013): Karela has hypoglycemic properties and improves glucose tolerance.
- Indian Journal of Clinical Biochemistry (2007): Reported that diabetic patients taking karela juice daily had lower fasting blood glucose and HbA1c levels.
These studies validate the traditional use of karela as a natural remedy for diabetes.
