Norwegian and Swedish researchers show that drinking three to five cups of espresso a day can significantly increase cholesterol levels.
Does drinking coffee affect cholesterol levels? Researchers from the Arctic University, the University of Oslo (Norway) and the University of Gothenburg (Sweden) have investigated the question and state that a cause-and-effect relationship between coffee consumption and excess fat in the blood would constitute a risk factor for cardiovascular circulatory diseases. According to the results published in the journal open heartthe explanation would lie in the chemical compounds naturally present in the caffeinated beverage.
In this study, scientists followed 21,083 coffee drinkers, 11,074 women and 10,009 men between 1974 and 2015. They asked her daily about her coffee consumption and her favorite and preferred way of preparing it. They also did blood tests.
The type of preparation has an influence
Verdict: Three to five cups of espresso a day are significantly associated with elevated cholesterol levels, particularly in men. This corresponds to an increased cholesterol level of 0.09 mmol/l in women and 0.16 mmol/l in men compared to people who do not drink coffee at all.
The method of preparation also plays a role, the researchers explain. Similarly, drinking six or more cups brewed with a French press coffee maker is associated with a similar increase in cholesterol levels in both sexes (0.30 mmol/L more in women and 0.23 mmol/L more in men). In contrast, drinking more than six cups of filtered coffee is associated with a 0.11 mmol/L increase in cholesterol in women but not in men. Instant coffee is associated with elevated cholesterol levels in both sexes, regardless of the amount consumed.
According to the researchers, the chemicals in coffee that can increase cholesterol vary depending on several factors. “The intake of each compound depends on the type of coffee, the degree of roast, the type of brewing process and the portion size, but also on the gender of the consumer,” the study authors summarize.
