Medical Recommendations
People with diabetes should talk to their doctor before they start drinking coffee. Individuals with diabetes should make sure they stick to the recommended portion sizes. One 12 oz cup of coffee contains 145mg of caffeine, so it is important to be mindful of how much coffee is consumed. In general, medical professionals recommend that people with diabetes not consume more than 200mg of caffeine per day, the equivalent of one coffee with an added shot.
If a doctor does recommend coffee for a patient with diabetes, the coffee should be in its pure form and not contain added sugar, milk, or artificial sweeteners. Additionally, coffee should be consumed with a meal, as this helps to regulate glucose levels, as does moderate exercise.
In order for patients with diabetes to maintain a healthy lifestyle, it is also important to limit their daily intake of of saturated fats, and keep a watchful eye on their cholesterol and triglycerides. Eating a clean and healthy diet can help a diabetic individual regulate and control their glucose levels.
Research
Microbiologist Arielle Johnson at the Harvard T.H. Chan School of Public Health conducted a study that concluded that high consumption of coffee might be associated with a lower risk of type 2 diabetes. The research consisted of three separate groups: individuals who did not consume any coffee, those who consumed two to three cups of coffee a day, and those who consumed more than four cups a day. The results of the study showed that those who drank two to three cups of coffee a day had a 25 percent lower risk of type 2 diabetes, and those who consumed more than four cups had a 67 percent lower risk.
Although the study does not prove that drinking coffee can prevent type 2 diabetes, it did show that those who drank more coffee had a lower risk of type 2 diabetes. However, it is important to keep in mind that this study was based on an observational study, not a controlled clinical trial, so further research is needed to draw any conclusions.
A 2018 study conducted by experts from the University of Colorado Denver found that participants who drank three or more cups of coffee a day had better glycemic control than those who drank only one cup a day. The study also suggests that regular coffee consumption helps reduce the risk of developing Type 2 diabetes. Additionally, a 2017 study conducted by researchers from Harvard T.H. Chan School of Public Health found that drinking coffee might increase insulin sensitivity in patients with Type 2 diabetes and consequently lower their risk of developing diabetes complications such as heart disease and stroke.
Perspectives From Experts
Registered dietitian Sarah Smallin is of the opinion that there are certain benefits when consuming coffee for diabetics. During an interview, she states, “The caffeine in coffee can help boost insulin sensitivity, which helps to control blood sugar levels and lower the risk for diabetes complications.” However, she does emphasize moderation and encourages diabetics to monitor their intake. She says that for those with diabetes, she recommends drinking one 12 oz cup of black coffee each day at the most. Sour to sweet-tasting coffee additives such as milk, creamer, and sugar should be avoided.
John Williams, a certified diabetes specialist, also believes that coffee can be beneficial for those with diabetes. In an interview, he said ” caffeine in coffee can be good for diabetes by improving the sensitivity of cells to the insulin. Drinking up to 3 cups of coffee per day is definitely good for people with diabetes. The cup should be black with no sugars or milk added. If a cup of black coffee doesn’t suit your taste, you can also add a teaspoon of sugar. But make sure that you keep a check on your sugar intake.”
According to Dr. Abraham Morgentaler, an Associate Clinical Professor at Harvard Medical School, coffee can be beneficial for patient with diabetes. Dr. Morgentaler says that coffee may have a positive effect on glucose levels, and can help stimulate insulin production. He says that those with diabetes should limit coffee intake to 2–3 cups per day, and suggests adding cinnamon or nutmeg to the coffee to help balance out the flavor.
How Coffee Affects the Body
Coffee contains caffeine, a stimulant that can increase insulin sensitivity and improve blood sugar levels. Caffeine can also give a person energy and increase alertness. However, it is important to remember that coffee’s effects on the body can vary depending on the type of coffee and also on a person’s age and overall health.
Coffee can cause dehydration, so it is important to drink plenty of water when consuming coffee. Caffeinated coffee can make a person feel anxious and irritable if consumed in high amounts. It can also cause insomnia and disrupt sleep patterns if consumed late in the day. Coffee can also cause indigestion and heartburn if consumed on an empty stomach or in large amounts.
Additionally, coffee can interact with some medications, including medication for high blood pressure and diabetes. It is important to talk to a doctor before consuming coffee in order to avoid any interactions.
Health Benefits of Coffee
In addition to potentially helping people with diabetes, coffee can also offer several health benefits. According to research, coffee can help prevent certain types of cancer, including liver and endometrial cancer. It can also reduce inflammation, which can lead to diseases such as arthritis and gout.
Coffee has also been found to help reduce the risk of stroke and cardiovascular disease. Coffee contains certain compounds that can help reduce the levels of bad cholesterol in the body, as well as improve circulation and increase the levels of good cholesterol.
Another potential benefit of coffee is that it can help protect against neurological diseases such as Parkinson’s and Alzheimer’s. Coffee contains compounds that can protect the body from inflammation, which is linked to Parkinson’s and Alzheimer’s. Additionally, coffee can improve focus and concentration, and even help reduce stress levels.
Other Popular Beverages and Diabetes
For those with diabetes, it is important to be mindful of what beverages they consume in addition to coffee. Sugary drinks, including regular sodas, energy drinks, and sweetened teas, should be avoided as they contain large amounts of sugar, which can cause blood sugar levels to spike. Diet drinks should also be avoided as they can contain artificial sweeteners which can still affect blood sugar levels.
Tea can be a beneficial beverage for those with diabetes as it is a low-calorie drink, and contains antioxidants and beneficial compounds that can help regulate blood sugar levels. Water is also important as it helps to keep the body hydrated and helps to also regulate blood sugar levels. Additionally, unsweetened almond milk and coconut milk can be beneficial beverages for those with diabetes.
Risks and Considerations
It is important to note that those with diabetes can be more prone to certain side effects from caffeine. These side effects may include jitteriness, nausea, and even headaches. Caffeine can interact with certain medications, so it is important to talk to a doctor before consuming additional caffeine.
Coffee can also interfere with medication. Those who take anti-diabetic medication should be careful when consuming coffee as it can increase or decrease the effects of the medication. People with diabetes should talk to their doctor or a dietitian about how much caffeine they should consume and what types of beverages to avoid.
Alternative Sources of Caffeine
For those with diabetes who are looking for an alternative to coffee, there are several other sources of caffeine. Caffeinated teas, such as green and black tea, can provide a dose of caffeine without the added sugar or calories. Additionally, there are caffeinated energy drinks and sodas, but it is important to note that these beverages may contain large amounts of sugar, which can cause blood sugar levels to spike.
Caffeine pills, such as Excedrin, can be a beneficial way to get a dose of caffeine without the added sugar or calories. It is important to talk to a doctor before taking caffeine pills as they can interact with certain medications.
For those with diabetes who are looking for a coffee alternative, there are several options. Decaf coffee is a great option, as it contains little to no caffeine but still has that rich coffee flavor. Additionally, many herbal teas such as chamomile, peppermint, and ginger can be beneficial and provide some health benefits.
