I remember when I was growing up many people who were trying to live a “healthy” lifestyle avoid all caffeine, even that in chocolate. Of course, our idea of what is healthy changes over the years. It used to be that fat was the culprit to avoid. Now, it is carbohydrates. Next it will be….your guess is as good as mine.
With coffee, there is actually some strong evidence that it is a healthy choice for most people. Many studies have shown coffee to be a brain protector that could help prevent Parkinson’s and Alzheimer’s disease. There are also studies indicating that coffee might decrease the risk of diabetes. And there are compounds in coffee besides caffeine that could be beneficial. For instance, chlorogenic acid is the active ingredient in the popular weight loss supplement Green Coffee Bean Extract.
For a small percentage of the population, these benefits might be outweighed by some potential health concerns. About 12% of us have a genetic variation in a caffeine-detoxifying enzyme, known as cytochrome p450 1A2, which leads to slower breakdown of caffeine. One study indicated an increased risk of heart attack among individuals with these genes who drank coffee. The risk increased with higher coffee intake. Likewise, coffee drinkers with these variations had higher risk of breast cancer in another study. The study seemed to indicate that if they didn’t drink coffee they had a slightly lower risk of breast cancer than the rest of the population.
So how do you know if you are in this 12%? Genetic testing is now a viable option since it has become inexpensive. Many people with this genetic variation can tell because caffeine will affect them longer or even cause strange symptoms. They might notice that a cup of coffee with supper or even lunch or breakfast keeps them awake at night.
For everyone else, some caffeine seems like a safe and possible protective part of the diet, but to quote one of my herbal medicine instructors, “the proper dose for this herbal medicine is 1-2 cups per day.” Over reliance on coffee to keep us energized might be masking underlying health issues to need to be addressed.
