Coffee is a beverage beloved by millions around the world, and morning coffee is a daily ritual for many people, as they cannot start the day without a cup of coffee before going to work.
As for the benefits of coffee, studies have proven that coffee without additives is better for health, explaining that the relationship between coffee consumption and changes in mortality risk varies with the amount of sweeteners and saturated fat (milk) added to the coffee.
Benefits of Coffee Without Additives
A study conducted at Tufts University found that black coffee and coffee low in added sugar and saturated fat were associated with a 14% lower risk of death from all causes, compared to no coffee consumption.

The same association was not observed with coffee containing high amounts of added sugar and saturated fat.
Key Findings of the Study
The study analyzed data from nine consecutive cycles of the National Health and Nutrition Examination Survey in the United States, from 1999 to 2018, linked to data from the National Mortality Index.
Coffee consumption was categorized by type (caffeinated or decaffeinated), sugar content, and saturated fat. Results included all-cause mortality, cancer, and cardiovascular disease.
Half a teaspoon of sugar
Low added sugar (from granulated sugar, honey, and syrup) was defined as less than 5% of the daily value, or 2.5 grams per cup, or about half a teaspoon of sugar.
Low saturated fat (from milk, cream, and half-and-half) was defined as 5% of the daily value, or 1 gram per cup, or the equivalent of 5 tablespoons of 2% milk, or 1 tablespoon of light cream.
According to Medical Express, consuming at least one cup of coffee per day was associated with a 16% lower risk of all-cause mortality, while this increased to a 17% lower risk for consuming 2-3 cups per day.

Coffee and a Lower Risk of Death
Consuming more than 3 cups per day was not associated with additional reductions. The association between coffee and a lower risk of cardiovascular death weakened when coffee consumption exceeded 3 cups per day.
No significant associations were observed between coffee consumption and cancer mortality.
During the study, researchers noted that adding sugar and saturated fat may reduce coffee's mortality-lowering benefits.
