Coffee’s Effect On Diabetes

Coffee being one of the most commonly consumed beverages has attracted a lot of debate for its health benefits and disadvantages. There are several compelling researches that showcase the benefits of coffee consumption and how it can lower the risk of developing type 2 diabetes. However, for those who already have type 2 diabetes, drinking coffee may not be a good idea. This may all sound too confusing, so let’s learn in-depth about the effects of coffee on diabetes. 

Some Good News For Coffee Lovers

Some researches show that coffee can lower the risk of type 2 diabetes. This benefit is attributed to the high amounts of magnesium in coffee. Coffee also contains a rich amount of chromium, and the mix of the two minerals can be very helpful in improving insulin sensitivity. 

A study conducted in 2009 that involved over 40,000 participants shows that consumption of three cups of caffeinated beverages like tea or coffee a day can lower the risk of developing type 2 diabetes. 

Americano or black coffee, in particular, can be a good idea as they contain zero calories. However, moderate consumption is the key to good health. It is wiser to have coffee in the afternoons if you are affected by the dawn phenomenon (high blood sugar levels in the morning).

Things To Try

Those who are concerned about the consumption of coffee can try a simple experiment. On a morning when the blood sugar level is in range, have a cup of coffee and check the levels within 1-2 hours of consumption. Some patients may need one unit of fast-acting insulin with a cup of coffee. For a better comparison, test the body’s response by removing coffee from the morning routine for a few days. If your sugar levels spike up or if you experience any discomfort, limiting your coffee intake is something that must be taken into consideration. It is also a wise option to consult your doctor or dietitian with regards to the consumption of coffee if you are diabetic. 

What Research Suggests

The health benefits of coffee for diabetes patients differ in every individual depending on their food habits, lifestyle choices and more. A Harvard research that lasted over 20 years observed more than 100,000 people, concentrating on a 4 years period, concluded that people who had more than one cup of coffee had an 11% lower risk of developing type 2 diabetes. While those who reduced the consumption of coffee by one cup per day heightened the risk of developing diabetes by 17%. 

Another small study included only men which traced an acute rise in blood sugar for ones who had decaffeinated coffee. 

A small pilot study says people with type 2 diabetes may have reduced blood sugar levels if they have coffee before their workout. While another study says that people with type 1 diabetes could get slightly reduced blood sugar levels if they take caffeine supplements. However, they are also warned that this could increase the risk of late-onset low blood sugar. Therefore, it is essential to consult an expert.

Substituting Regular Add Ons To Coffee

Some alternative sweeteners for coffee can be used, such as monk fruit, for anybody who needs a sweetener, as this could be a healthy alternative. However, the gradual reduction of sweeteners and slowly cutting it out altogether is a healthy choice. There are many other natural substitutes to milk or cream as well, these include almond milk and coconut milk.

Additional Health Benefits 

Polyphenols found in coffee are molecules with anti-inflammatory properties which can help keep the heart healthy. People with diabetes are usually at higher risk of developing heart diseases and stroke. Therefore, consuming foods with high anti-oxidants can help lower the risks of heart complications in the long run.

The Last Word

While earlier studies said coffee can be considered harmful, newer studies suggest it may have some health benefits after all. Looking at just one component of the diet cannot be sufficient, as several other factors can contribute to diabetes. Coffee has shown to provide protection against type 2 diabetes and moderate consumption or the consumption of decaf coffee can provide certain benefits to diabetes patients. However, it is advised to consult an expert before making any dietary changes.
