In addition to providing a temporary boost in brain activity and memory, regular coffee consumption may help prevent cognitive decline associated with Alzheimer’s disease and other types of dementia. In one promising Finnish study, researchers found that drinking three to five cups of coffee daily at midlife was associated with a 65 percent decreased risk of Alzheimer’s and dementia in later life. Interestingly, the study authors also measured the effect of tea drinking on cognitive decline, but found no association.
In the Hungry For Change Book we discuss the addictive nature of caffeine and when consumed in large quantities, can lead to adrenal fatigue. Coffee is also a diuretic, meaning it purges water from your body. That said, if you want to function at a high level and remain well hydrated, then it would be a better choice to replace coffee with a natural alternative. The list below provides some great tasting substitutes.
The best water to drink is water that has been passed through a filtering process. Common and inexpensive filters are available, such as carbon filters like the ones Brita makes. The best filter is a reverse osmosis filter that puts the water through a multi-step process to remove microbes, pesticides, metals, and other toxins. This can be installed under the sink. It's a great filtering system and cheaper over the long run. Avoid water in plastic bottles, which contains phthalates, a toxic petrochemical. Mineral water or still water in glass bottles is also acceptable.
Anybody who’s serious about health knows the importance of a healthy cardiovascular system. What you may not know is by simply drinking 1 to 2 cups of coffee per day, you could significantly reduce your risk of cardiovascular disease-related death. According to a Japanese study of more than 76,000 participants, men who hit this sweet spot (1-2 cups per day) consuming one to two cups of coffee daily reduced their risk of dying from a cardiovascular disease by as much as 38%. Of course, this still doesn’t excuse you from doing actual cardio. (And if you really hate it that much, check out 8 cardio workouts for the guy who hates cardio.)
While they say that the results support moderate coffee drinking as a relatively healthy habit, both Poole and Guallar say the findings don’t go far enough to prompt anyone to change their coffee-drinking habits in the hopes of improving their health. The study did not confirm, for example, that people who do not currently drink coffee should start adding a cup or two a day in order to lower their risk of getting heart disease or any of the other chronic conditions studied. The data also do not support the idea that current coffee drinkers should drink even more coffee to enhance whatever benefits they might be receiving. Too much coffee, the data suggest, starts to bend the benefit curve back down.
