According to Dr. Howard LeWine of the Harvard Health Publishing Center (USA), for the majority of healthy adults, drinking about 2-3 cups of coffee a day is considered a reasonable consumption level, as long as it does not cause insomnia, restlessness or anxiety. Many studies have also noted that coffee may be associated with reducing the risk of type 2 diabetes, liver disease and some cardiovascular problems.
Experts recommend that people who drink 2 cups of coffee a day should avoid adding too much sugar, fatty cream or sweetening syrup. These ingredients can increase calories, sugar and saturated fat, thereby reducing the inherent health benefits of coffee.
Besides, the time to drink coffee is also very important. Caffeine can stay in the body for many hours, so you should limit drinking it in the late afternoon or evening to avoid affecting sleep quality.
Drinking about 2-3 cups of coffee a day may be associated with a lower risk of dementia than people who drink less or no coffee. However, experts emphasize that coffee should only be part of a healthy lifestyle, alongside a balanced diet, regular exercise and good sleep.
