Coffee and Diabetes

Coffee and Diabetes



Coffee contains different chemicals, some having beneficial effects whereas others with less beneficial effect, e.g. caffeine which can impair insulin in the short term.

Caffeine and blood glucose levels
Regular high caffeine consumption, over a 4 week period, has indicated impairing insulin sensitivity in patients with type 2 diabetes.

Whilst the researchers found
The relationship between higher coffee consumption and lower sensitivity to insulin found by researchers:-
The rapid transition with high consumption of coffee may produce an atypical or emphasised response by human body.

Coffee has been shown lowering risks of following dieseases:

  • Type 2 diabetes
  • Cancer – such as endometrial cancer and aggressive prostate cancer
  • Cardiovascular disease
  • Strokes
  • Alzheimer’s disease
  • Parkinson’s disease

Coffee contains polyphenols, a molecule with anti-oxidant properties which are widely believed helping prevent inflammatory illnesses, e.g. type 2 diabetes, and anticarcinogenic (anti-cancer) properties.

Coffee contains mineral magnesium, chromium and polyphenols.  Greater magnesium intake has been linked with lower rates of type 2 diabetes. The blend of these nutrients can have effect improving insulin sensitivity, which may offset the opposite effects of caffeine.

Coffee and prevention of diabetes
Coffee and its effect on risks of developing type 2 diabetes have been studied a number of times and has indicated a notably lower risk of type 2 diabetes being associated with coffee drinkers.

Researches have been performed on:-
A 2009 study of 40,000 participants
Consumption of 3 cups of tea or coffee a day leading to a 40% lower risk of type 2 diabetes developing.

A study of healthcare professionals in the US and UK, published in 2014
People increasing their coffee consumption experienced 11% decrease in the risk of type 2 diabetes over the next 4 years.

Lattes and syrups in coffee
Coffees with syrup could be problematic for people either with, or at risk of, diabetes.  If you have diabetes, or are at risk of diabetes, it is better reducing sugar consumed.

Lattes present two considerations: the number of calories in the latte and the amount of carbohydrate.

Skinny lattes are usually made with skimmed milk, some sweetened which will raise their calories.  Milk, whether full fat or skimmed, tends having around 5g of carbs per 100g.  A regular unsweetened skinny latte can contain between 10 and 15g of carbohydrate.

Ideal cups per day
Experts say sipping two to three cups a day is probably fine.  If you’re having a tough time controlling your blood sugar, it may be worth cutting out coffee.
