It's no surprise for those of us paying attention that there are many studies demonstrating health benefits from the so called "Super Foods". A slew of studies have shown that these foods can help prevent basically everything bad in our lives, but rarely are these studies peer-reviewed and can hold up under the scrutiny of multiple independent clinical trials.
Several studies, however, have not only shown coffee to be the ultimate super food, but unlike many of these other studies, these represent some of the largest health studies in history. Moderate coffee consumption actually reduces your risk of arterial blockage.
It can help lower your risk of a stroke -
If you a have a few cuppas throughout the day, don't worry, you're probably doing more good than bad. Evidence shows that those who drink a moderate amount of coffee (one-three cups/day) have a lower incidence of stroke compared to non-coffee drinkers.
"The antioxidants in coffee may help to protect the arteries from the damage of inflammation. But be aware that an excessive coffee consumption of five cups or more has been linked to higher heart disease risks," says Elouise.
Increasing Lifespan -
The biggest clinical trial of coffee in history was a Harvard study that concluded in 2011, which followed roughly 500,000 participants and correlated coffee to a variety of risk factors and benefits. Mortality in the study did not improve with statistical significance, but it also did not drop as well. This indicates that, at best, the research so far is muddy on any longevity benefits for regular coffee consumption.
Reducing the Risk of Diabetes -
Studies show that those who drink coffee regularly (four cups or more/day) had a decreased risk of developing Type 2 Diabetes.
It has been suggested that the antioxidant phytochemicals in coffee such as chlorogenic acid and quinides may increase the cell's sensitivity to insulin, thereby regulating blood sugar levels.
Coffee can help prevent Dementia -
Research suggests that enjoying one-five cups/day may help reduce the risk of Alzheimer's disease and Dementia.
"The antioxidants in coffee increase the effects of neurotransmitters involved in cognitive function. These antioxidants may prevent damage to brain cells."
It strengthens your brain function and energy -
Two Java jolts a day can help kick-start your memory helping to increase your intelligence whilst also boosting your energy levels.
"Caffeine has a stimulant effect on the brain by blocking an inhibitory neurotransmitter in the brain called, Adenosine. This results in enhanced levels of other neurotransmitters, such as dopamine and norepinephrine, increasing the 'firing' or neurons. Coffee improves moods, energy levels, reaction time and cognitive function in general".
Selecting Among the Various Types of Coffee -
There are various types of coffee, including the types of roast, as well as the types of beans themselves. Arabica beans are the most common ones available. Typically, the studies have found the darker and stronger the coffee, the better. This helps to prevent damage to the person's stomach lining due to the acidic qualities of coffee by drinking large amounts of it. The Harvard study noted above found that coffee contains a particular substance called "cafestol", which is a potent stimulator of our bodies' cholesterol levels. Coffee made through espresso machines or cafetieres contains this protein, however, those made from traditional drip brewing is strained out. It's advised for those worried about cholesterol levels to strain their coffee they drink as a result.
Coffee offers a lot of benefits, though calling it a "super food" may be something that can only be validly stated after more research. Compared to the other famous "super foods" being written about, the data for coffee having significant health benefits is much greater. There are dozens of studies that have looked at a variety of health benefits for coffee so far, and particularly raw, unroasted coffees appear to offer significant benefits. It's clear that regular coffee drinking, even significant levels of coffee each day, should not be harmful.
