Diabetes is one lifestyle disorder that needs proper attention and management to keep your blood sugar level in control. If not managed well, diabetes can lead to a lot of complications. Over the years, home remedies have proven to be effective in controlling and preventing diabetes. Green tea is one such ingredient that has a host of health benefits and one of them is prevention and control of diabetes. There are some more home remedies to keep diabetes in control. Here are 6 ways green tea can benefit diabetics:

  • In case of type 1 diabetes, the body is unable to produce insulin leading to high blood sugar levels. Green tea stimulates production of insulin, thereby preventing and controlling diabetes. Green tea prevents damage to the pancreatic beta cells [1] and helps in effective functioning of the pancreas which produces insulin. Epigallocatechin gallate (ECGC), an antioxidant present in green tea, delays the onset of type 1 diabetes too.
  • The polyphenols present in green tea have exhibited anti-diabetic properties [2] and help reduce oxidative stress, thereby boosting glucose tolerance. The caffeine present in green tea in small amounts is known to lower insulin sensitivity [5].

  • The catechins in green tea have a beneficial effect against glucose and lipid metabolism disorders which are caused by type 2 diabetes. The catechins [1] also inhibit the digestive enzymes resulting in a decrease in glucose production from carbohydrates. This leads to lower glucose levels, thereby controlling diabetes.
  • Obesity is one of the leading causes of type 2 diabetes. Green tea boosts metabolism and shows anti-obesity activity[3]. Green tea lowers fatty acids and triglyceride levels thereby controlling obesity. This helps in preventing complications that may arise in obese diabetic patients.

  • Diabetes is a result of hyperglycaemia and glucose intolerance due to insulin deficiency or insulin resistance. Hyperglycemia may also lead to ailments like diabetic retinopathy by promoting oxidative stress. Green tea has a potential in preventing diabetic retinopathy [4] if consumed regularly in moderation.
