New Study on Coffee Consumption and Health Benefits
Research suggests a potential correlation between black coffee consumption and reduced mortality risk
Researchers from Tufts University have conducted a study that delves into the effects of coffee consumption on mortality risk and overall health. The study, which was based on the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2018, provides valuable insights into the potential benefits and risks associated with drinking coffee.
Lower Mortality Risk with Moderate Coffee Consumption
The study found that consuming one to two cups of caffeinated black coffee daily is associated with a 14% lower risk of all-cause mortality compared to non-coffee drinkers [2][3][5]. Furthermore, drinking one cup of black coffee per day is linked with a 16% lower risk of all-cause mortality [6].
Cardiovascular Health and Longevity
The bioactive compounds in coffee, such as antioxidants, may promote cardiovascular health and reduce inflammation [1][2]. As a result, the study suggests that consuming plain coffee without excessive add-ins may contribute to longevity and overall well-being [1][3].
Potential Risks of Adding Sugar and Saturated Fat
However, the study also discovered that the addition of milk, cream, and half-and-half increases the saturated fat content of coffee [4]. Exceeding the "low added sugar" and "low saturated fat" thresholds defined for the study nullifies the link between coffee consumption and lower mortality risk [7].
The study found that a 1/2 teaspoon of sugar per 8 oz of coffee constitutes low added sugar in coffee [8]. Additionally, one to two cups of coffee with low sugar and fat are linked with a 14% lower risk of all-cause mortality [3].
The study's findings support the Dietary Guidelines for Americans which recommend limiting added sugar and saturated fat [9]. Consuming high amounts of sugar and saturated fat can lead to various health issues, including increased risk of obesity, diabetes, and cardiovascular diseases [3].
Fang Fang Zhang is the senior author of the study [10]. The study also analyzed the type of coffee (caffeinated or decaf) and data from 46,000 adults aged 20 and older [1][2][3].
Interestingly, the study found no associations between drinking coffee and the risk of death from cancer [1]. However, the study did not find any definitive evidence to suggest that coffee consumption reduces the risk of cancer.
Overall, the study suggests that while coffee itself can be beneficial, the way it is prepared—without excessive sugar and saturated fat—plays a crucial role in maximizing its health benefits. Moderate consumption of black coffee or coffee with minimal amounts of added sugar and saturated fat can potentially lower the risk of all-cause mortality and promote cardiovascular health.
- The study implies that the bioactive compounds in coffee, such as antioxidants, found in black coffee may contribute to longevity and overall well-being by promoting cardiovascular health and reducing inflammation.
- Exceeding the "low added sugar" and "low saturated fat" thresholds defined in the study nullifies the link between coffee consumption and lower mortality risk, as the addition of milk, cream, and half-and-half increases the saturated fat content of coffee, potentially leading to various health issues like obesity, diabetes, and cardiovascular diseases.
