The coffee is the company of many people every day, it seems that not only helps us to.
Wake up, but also contributes to better mental function by increasing the concentration, improving attention and positive influencing short-term memory. In the above we must add a growing number of studies show that moderate coffee consumption may have beneficial effects on heart health.
Specifically, a meta-analysis carried out in 2012 and examined the results four major surveys showed that moderate coffee consumption systematically (up to 4 cups a day), it is possible to reduce the risk of heart failure. This correlation was attributed to the effect of coffee and caffeine intake in hypertension and diabetes mellitus type II, two parameters that are risk factors for heart failure.
The positive effects of coffee consumption has also been confirmed for the Greeks, and in accordance with the CARDIO study conducted in Greek population in 2000 seemed that people who used moderate coffee consumption (2 cups of coffee a day) had a 30% lower risk of coronary syndrome compared to those who did not consume coffee.
But how coffee affects specific aspects of cardiovascular health?
The role of coffee in hypertension: Studies today show that consuming moderate amount of coffee does not appear to affect blood pressure in people who consume coffee regularly. Especially interesting is the fact that drinking a cup of coffee can reduce the blood pressure values within the first two hours following consumption in healthy people with mild hypertension.
Shield for type 2 diabetes: Studies indicate that moderate, but regular coffee consumption is likely to help reduce the risk of type 2 diabetes.
A possible mechanism to which is attributed the beneficial effect of coffee on heart health is the content of antioxidants. According to scientific data of recent years, the coffee seems to be a source of antioxidant ingredients for example one instant coffee serving contains 0.43 g of antioxidants. From the main antioxidants found in a cup of coffee are polyphenols, which appear to have potent antioxidant, protecting lipids of cell membranes from free radicals, helping to protect the body from oxidative stress.
Furthermore, coffee is rich in chlorogenic acid, a component with a strong antioxidant effect.
What is particularly interesting is that similar protective effect seems to have had and decaf coffee! This further supports the view that the possible positive effects of moderate coffee consumption on cardiovascular function may be due to the high presence of antioxidant components.
In conclusion, one could say that the effect of coffee on cardiovascular function is a matter of particular research interest for years. According to scientific data, the moderate consumption (200-300mg of caffeine), quantity translates into 2-4 cups of instant coffee or 4-6 cups Greek day not appear to be associated with risk of cardiovascular diseases. On the contrary, people tend to consume coffee in moderation, appears to have beneficial effects for the health of their heart.
