Coffee drinkers might be healthier than non-drinkers

Coffee drinkers may have a better diet than their non-coffee drinkers, according to a new study published in the journal Health Psychology.

The study suggests that coffee drinkers could have a higher metabolic rate than non–coffee drinkers, which may have implications for weight management.

The results of the study, which involved the use of dietary records from a national sample of 5,000 British adults aged between 18 and 54, also suggest that coffee consumption could lower blood pressure and other cardiovascular risk factors.

The researchers say that the study is “the first systematic assessment of coffee drinking patterns among adults aged 18 to 54 years” and adds that the results should be useful to health professionals in treating patients who may be at increased risk for cardiovascular disease.

The authors point out that coffee drinking may also improve overall metabolic health by reducing stress, reducing blood pressure, and lowering triglycerides.

There is evidence that coffee might reduce blood pressure when combined with exercise.

However, coffee drinkers tend to have lower levels of cardiovascular risk markers such as high cholesterol, high triglycerides, and high blood pressure than non‐coffee drinks, and the association between coffee consumption and cardiovascular risk is unclear.

In recent years, researchers have been interested in the health effects of coffee, as it can be consumed in many different forms and is known to help lower blood pressures, such as in diabetics.

However the results of these studies are conflicting, with some suggesting that coffee can increase blood pressure.

The findings could have important implications for people with heart disease.

However it is also known that coffee is not a great source of antioxidants, as some studies have found.

A study published earlier this year in the American Journal of Preventive Cardiology suggested that coffee intake may reduce risk factors for cardiovascular diseases, including high blood glucose, diabetes, and hypertension.

The research team, led by Dr Toni D’Agostino of the University of Arizona, found that people who drank coffee more than 30 cups a day had a slightly lower risk of developing high blood sugar and type 2 diabetes than those who drank fewer than 25 cups a week.

These findings are important, as coffee consumption has been linked to a reduced risk of death from heart disease and stroke.

“Coffee drinkers who drink a lot may be more likely to have metabolic syndrome, which is a metabolic syndrome where people have more than one metabolic risk factor,” Dr D’Anastasio said.

“They’re more likely than non­coffee drinking individuals to have cardiovascular disease, but they also have a lower risk for high blood pressures and triglyceride levels.”

The study found that, although coffee drinkers were less likely to develop cardiovascular disease compared with non‐drinkering drinkers, they were also more likely on average to have low triglyceride, high blood cholesterol, and low HDL cholesterol levels.

This suggests that people drinking more coffee are more likely of having metabolic syndrome.

The takeaway: coffee may lower blood-pressure and heart-health riskThe authors conclude that “the findings of this study are relevant to the general public, particularly those who are currently consuming coffee in a low-fat, high-calorie, high‐protein and low‐sugar way”.

They also point out the “very important role” that coffee plays in maintaining healthy lipid levels.

“While the current results cannot rule out the potential health effects from coffee consumption, they are suggestive of an important association with reduced blood-sugar, reduced blood triglycerides and elevated HDL cholesterol,” the authors concluded.

Coffee drinking might improve metabolic health among people with type 2 hypertension and diabetes, but the link is not clear Source: New Scientist article Coffee consumption might be associated not only with reducing high blood-poli­nes and low blood-cholesterol levels, but also with a lower cardiovascular risk marker.

The current study examined the association of coffee and diabetes and metabolic syndrome among 7,500 men and women aged 18 and over in the United Kingdom.

Researchers recruited the participants by telephone and asked them to complete a questionnaire about their consumption of coffee (regular, decaf, or tea) and a measure of metabolic syndrome (high blood sugar, high fasting glucose, low HDL, and triglycerid levels).

Coffee drinkers had a higher risk of metabolic symptoms such as hypertension, type 2, type 3, hypercholesterolemia, and elevated blood pressure compared with those who did not drink coffee.

However there were no differences between the two groups when the researchers assessed the association with cardiovascular risk biomarkers. These
