Inflammation in the body, in particular low-level, ongoing inflammation, has been linked to an increased risk of serious and even deadly conditions, including heart disease, cancer, and strokes. While a certain amount of inflammation is unavoidable, there has been evidence to indicate the certain foods may be associated with increased levels of inflammation in the body.
Caffeine, especially when found in coffee, has been linked to inflammation, but the correlational studies conducted so far cannot say for sure whether the caffeine is the cause of the problem, or if there might be something else at work.
Making things more interesting is the fact that several studies have actually suggested that caffeine may be an anti-inflammatory, at least when consumed at low to moderate levels.
According to the National Institutes of Health a great deal more researched is planned for the near future, to determine which foods have an inflammatory or anti-inflammatory effect on the body, and in particular, what role caffeine may play in this hotly debated condition.
It is important to note that different people will have different reactions to different foods; some can tolerate foods that cause inflammation in others, and vice versa. There may be some trial and error in determining which foods you can tolerate, and which you cannot.
