Caffeine increases the risk of heart disease
Research has shown that regular caffeine use has little or no effect on blood pressure, cholesterol levels or risk of heart disease. Studies show that while first-time caffeine use can cause a slight increase in blood pressure (similar to that experienced when walking up stairs), the changes are minimal and disappear with regular use.It has also been found that only boiled, unfiltered coffee, such as that taken in some Scandinavian countries, elevates cholesterol. It seems the oils in the coffee that are not filtered out are responsible for this effect, not the coffee or caffeine. Consumption of caffeine-containing beverages does not typically affect cholesterol levels.
