How Coffee Slows Aging: Beneficial Groups and the Ideal Daily Intake
A new study finds that drinking 3 to 5 cups of coffee daily may slow biological aging in patients with schizophrenia, bipolar disorder, and psychotic depression, while excessive intake may have negative effects.
A recent study published in BMJ Mental Health shows that consuming 3 to 5 cups of coffee per day can slow biological aging by up to five years in individuals with serious mental health disorders, including schizophrenia, bipolar disorder, and psychotic depression.
The study, which involved 436 participants from psychiatric units in Oslo, Norway, found that moderate coffee drinkers had longer telomeres—cellular indicators associated with delayed aging—compared to non-drinkers or heavy coffee consumers.
The effect is attributed to antioxidants in coffee, such as chlorogenic acids and trigonelline, which reduce oxidative stress, calm inflammation, and protect DNA, rather than caffeine alone.
Researchers warned that exceeding 5 cups per day may increase stress, disrupt sleep, and accelerate aging, potentially causing sleep disturbances, anxiety, high blood pressure, and digestive issues.
The study also highlighted that certain foods can shorten telomeres, including processed meats, added sugars, refined grains, and high-glycemic foods.
Limitations of the study include reliance on self-reported coffee consumption and lack of information on coffee type and preparation methods, emphasizing the need for further research.
Regular health screening is one of the most important steps to maintain good health and detect diseases early. The essential medical checkups for every age help in preventing complications and ensuring a healthier life.
Many people, after doing medical tests, receive their results and immediately start looking at numbers and unfamiliar terms like (High – Low – Normal) without fully understanding what they actually mean.
When dealing with medical services, many people come across different titles for doctors such as “Specialist” and “Consultant”, which can sometimes create confusion about what each title actually means and how they differ from each other.
Choosing the right time to visit a doctor is not a random decision. It can directly affect how quickly a condition is diagnosed and how effective the treatment will be. Many people delay visiting a doctor or go at the wrong time, which may lead to worsening symptoms or delayed care.
