Type 1 diabetes results from pancreas not producing insulin and the treatment involves injecting insulin to the body to control blood glucose.

In a 1990 study  researchers treated insulin dependent type 1 diabetes patients each with 100 g/day of defatted fenugreek seed powder equally divided between lunch and dinner with diets of similar calorie value for 10 days.

Compared to the patients with no fenugreek in their diet, the patients with fenugreek added diet showed the following:

  • Reduced fasting blood glucose
  • Improved glucose tolerance
  • 54% reduction in 24 h glucose excretion
  • LDL cholesterol (risk for heart) and triglyceride levels were also significantly reduced

However HDL cholesterol (good cholesterol) level remained unchanged.

Fenugreek Water Reduces Fasting Blood Glucose in Type 2 Diabetes

11/ 18 type 2 diabetic patient consumed with 10 g of fenugreek seed powder/ day soaked in hot water were treated VS. 7/18 were given similar amount of fenugreek seeds powder soaked in yogurt for a duration of 8 weeks.

The blood glucose and glycosylated hemoglobin (HbA1c) level were measured each month for six months.

A fasting blood glucose reduction was seen on 5th month and HbA1c reduction was observed on 6th month. (Ref: American Diabetes Association. Standards of medical care in diabetes – 2015. Diabetes Care. 2015;38:S1–94. [Google Scholar])

  • If the blood sugar control was due to the fiber, the results would have been immediate.
