Harvard 30-year study: A cup of coffee a day can help prevent dementia and chronic diseases and achieve healthy aging

A cup of coffee every morning is not only refreshing, but also an important habit for maintaining healthy aging. According to the latest research from Harvard University in the United States, taking a cup of coffee every day can significantly reduce the risk of women suffering from chronic diseases such as dementia, diabetes, and cancer, and help maintain a good psychological state and action.

The senior has been tracking for 30 years, and more than 40,000 women have been analyzed. This study was directed by Dr. Sara Mahdavi of Harvard University's Public Health Institute. It analyzes the health data of more than 47,000 women in the Nurses’ Health Study. It tracks the health of more than 30 years, covering nutritional intake, living habits, chronic diseases and mental health. The study found that women who consumed an average of about 315 mg of caffeine (about 3 cups of coffee) per day in middle age (45 to 60 years old) had a significantly higher chance of healthy aging.

The research team defines "healthy aging" as living to over 70 years old, without 11 major chronic diseases including cancer, diabetes, cardiovascular disease, etc., without cognitive impairment or memory degeneration, no mobility difficulties, and maintaining good mental health. According to the results, only about 8% (3,700 people) meet all standards, and they generally have a fixed habit of drinking coffee.

One cup of coffee a day will reduce risks and increase health chances

The research further pointed out that if you take a cup of coffee a day, the chances of healthy aging can increase by 1%; if you take 2.5 cups a day, you can increase the possibility of healthy aging by 2 to 5% in both physical, psychological and cognitive functions.

However, the study clearly pointed out that "caffeinated coffee" has a protective effect, and tea and uncaffeinated coffee have not observed the same benefits.

Soda and sugary drinks, the aging risk increases

It is worth noting that carbonated beverages and sugary drinks may have a negative impact on healthy aging. Research shows that drinking a glass of sugary drinks such as cole and soda every day will reduce the chance of healthy aging by 19%; the possibility that meets the standard of healthy aging has dropped to 25%.

In fact, past studies have pointed out that coffee has potential health benefits, including reducing the risk of cardiovascular disease, hypertension and Alzheimer's disease. This new study further integrates the mind, mind, action and disease prevention aspects, and evaluates the impact of coffee on aging for the first time from multiple aspects.

Dr. Sara Mahdavi emphasized: "These results show that small but stable habits can cause significant differences in long-term health. Catering caffeine-containing coffee with proper exercise, balanced diet and no smoking may help maintain physical and mental health in later years."
