This study aimed to assess the potential effects of long-term intake of caffeine and habitual consumption of coffee and tea on the occurrence of cardio-renal events among an Iranian population with low coffee and high tea consumption. Because These amounts seem to be of optimum benefit. More consumption than this did not change the findings.

Cardio-renal events

Authors write that coffee is connect to a reduce risk of prostate cancer; Alzheimer’s disease and Parkinson’s disease. Astrid Nehlig; a research director at France’s National Institute of Health and Medical Research in a statement said; “It is difficult to calculate; but my feeling is that drinking coffee possibly adds another couple of years to your life.” He added that more focus and attention could be the reason behind this longevity.

“Moderate coffee consumption (e.g. 2-4 cups/day) was associated with reduced all-cause and cause-specific mortality, compared to no coffee consumption.” In yet another study from Australian researchers; it was found that there was an optimum amount of coffee that was beneficial.

Optimum amount of coffee

The new study was published this month in the journal American Journal of Clinical Nutrition and was titled; “Long-term coffee consumption; caffeine metabolism genetics, and risk of cardiovascular disease: a prospective analysis of up to 347,077 individuals and 8,368 cases.”

Researchers from the University of South Australia in their study published this month set out to ascertain the amount of coffee that was beneficial for health. They noted that drinking six or more cups of coffee per day could be harmful for health and raise the risk of heart disease by up to 22%.

The researchers write that one in six persons are suffering from heart disease in Australia. The World Health Organization calls cardiovascular disease the leading cause of death as well as one of the most preventable causes of death. Dr Ang Zhou and Professor Elina Hyppönen of the Australian Centre for Precision Health looked at the long term effects of coffee consumption and heart disease.

Raising blood pressure

They explain that research shows that excess coffee can harm the heart by raising blood pressure. They write that this is the first study that outlines the upper limit of coffee consumption in terms of benefit and harm. Prof Hyppönen in a statement said; “Coffee is the most commonly consumed stimulant in the world  it wakes us up; boosts our energy and helps us focus but people are always asking ‘How much caffeine is too much.
‘” She added, “Most people would agree that if you drink a lot of coffee, you might feel jittery; irritable or perhaps even nauseas that’s because caffeine helps your body work faster and harder, but it is also likely to suggest that you may have reached your limit for the time being. We also know that risk of cardiovascular disease increases with high blood pressure; a known consequence of excess caffeine consumption.”
