Advantages Of Coffee for Diabetes Patients

Some compelling research suggests that coffee helps to reduce the risk of developing type 2 diabetes. People who increased their intake daily by a cup experienced an 11% reduced risk of diabetes. Drinking coffee for a long period also has shown a positive correlation to glucose and insulin sensitivity. This tolerance leads to protection from prediabetes and diabetes for adults aged between 20 and 70 years. 

For those with high sugar, it  is recommended to limit the amount of coffee, based on their diet.

Ways to Consume Coffee

Adding cinnamon, coconut oil, and cacao powder to your coffee can enhance the taste. For a more sweet drink, add natural sweeteners like Stevia, honey, or maple syrup as they are less harmful. A cold brew iced coffee is the best way to destress as it’s strong and smooth. Another way is to add boiling water to your instant coffee.


Best Time To Consume Coffee

The best time to drink coffee is in the morning post 9 am when the cortisol levels are dropping. Another time is after you have been awake for 3–4 hours. It’s not recommended to drink coffee on an empty stomach as it may trigger stress hormones and have a lower energizing effect.

Having coffee later in the day can negatively affect your energy levels and lead to sleep issues.

  • It can lead to insomnia in the elderly as caffeine remains in the body for 4–5 hours.
