Relationship between coffee and diabetes

The relationship between coffee and diabetes has been explored in numerous studies. Some suggest that coffee consumption may reduce risk of developing diabetes, while others have shown no significant association.

A study published in the Journal of Agricultural and Food Chemistry in 2018 found that coffee compounds may help prevent diabetes by inhibiting accumulation of a toxic protein that can damage insulin-producing cells in the pancreas.

However, a study published in the American Journal of Clinical Nutrition in 2014 found no significant association between coffee consumption and risk of developing diabetes in men and women.

Another study published in the Journal of Internal Medicine in 2018 found that high coffee consumption is associated with an increased risk of developing diabetes in people with a genetic predisposition for the disease.

Adverse effects of coffee on diabetes

Reduces insulin sensitivity

Caffeine is a stimulant that can negatively impact how the body utilizes insulin, the hormone that regulates blood sugar level. That can result in reduction in insulin sensitivity, making it challenging for individuals with diabetes to manage their blood sugar levels effectively.

Increases blood sugar level

Caffeine can directly increase blood sugar level by stimulating the production of cortisol, a hormone that prompts the liver to release glucose into the bloodstream. That can be problematic for people with diabetes who need to regulate their blood sugar level carefully.

Hypoglycemia risk

Consuming coffee on an empty stomach can lead to a drop in blood sugar level, as caffeine interferes with the liver's ability to release glucose. That can result in hypoglycemia, which can cause shakiness, confusion and dizziness and is dangerous if left untreated.

Interference with diabetes medications

Coffee can also hinder diabetes medications, especially those containing metformin.

Caffeine can reduce absorption of metformin, making it less effective in managing blood sugar level and increasing difficulty of managing diabetes.

Risk of dehydration

As a diuretic, coffee can enhance urine production, potentially causing dehydration. That can be problematic for individuals with diabetes, as dehydration can cause blood sugar level to rise. Drinking plenty of water and limiting coffee intake is vital to prevent dehydration.

Coffee and diabetes have a complex relationship that requires more investigation. While some studies suggest that coffee consumption may reduce risk of developing diabetes, more research is needed to confirm that.

If you have diabetes, it's important to discuss your caffeine intake with your healthcare provider and monitor your blood sugar level accordingly. Coffee and diabetes are two important topics that need to be understood and managed properly for overall health and well-being.
