Keep in mind that 3-4 cups of coffee means 3-4 eight-ounce (250mL) cups – not mugs, thermoses, and especially not Starbucks beverages. More than 4 cups can have the opposite effect, increasing the risk of heart disease and possibly even increasing the risk of death. 3-4 cups) but excessive consumption does not. In other words, moderate coffee consumption appears to be beneficial (i.e. With a lot of the research studies that have been done on coffee, the benefits are dose-dependent.

Plenty of other research has discovered benefits like lowered inflammation, blood pressure reduction, better athletic performance, improved focus and attention, reduced driver error, and more! This is just a small sample of the health benefits of drinking coffee. Promote Weight Loss: A German study found that coffee drinkers were more likely to maintain weight loss than those who don’t drink it. Reduce Alzheimer’s Disease: In the Cardiovascular Risk Factors, Aging and Dementia Study, drinking 3-5 cups of coffee in midlife was associated with a reduced risk of dementia and Alzheimer’s Disease by nearly 65% later in life. Prevent Parkinson’s Disease: A study found that caffeine intake may lower the risk of Parkinson’s even in individuals who are genetically predisposed to it. Reduce Cancer Risk: Moderate coffee intake has been linked to a reduced risk of liver, endometrial, breast, and possibly colon cancers. Prevent Type 2 Diabetes: Researchers at Harvard found that for every cup of coffee consumed, the risk of type 2 diabetes drops by 9%. Heart Health: Research combining data from 1,279,804 people discovered a 20% reduction in the risk of Cardiovascular disease in people who drank 3-5 cups of coffee a day.

Two genes were responsible for how caffeine is metabolized, two were associated with how we feel rewarded from it, and two genes were discovered that regulate fat and sugar in the bloodstream in response to it.Īntioxidants: It has more antioxidants than green tea or chocolate, fighting free radical damage that underlies many diseases including cancer. Ī really cool study performed at Harvard University looked at 120,000 people and found 6 genetic variations in how people metabolize and become addicted to caffeine. Others have a genetic difference in the sensitivity of their adenosine receptors to the caffeine molecule. Some people make less of the CYP1A2 enzyme that the body uses to break down caffeine. Science has been able to explain why these different sensitivities exist. The third group of individuals are those who metabolize it “normally”. For us, drinking a single cup of coffee could keep us awake for hours, possibly even preventing us from falling asleep that night. Other people (myself included) are overly sensitive to caffeine, reacting to even small amounts with shakiness, rapid heart rate, and insomnia. These types of individuals make up 10% of the population who have limited sensitivity to it. We’ve all met those people who claim they can drink a shot of espresso and still fall asleep an hour later. Scientists have identified 3 different levels of caffeine sensitivity based on your unique genetic makeup. If you drink a cup of coffee around noon, paraxanthine may the reason you can’t fall asleep at 10 pm. What this means is that even though the stimulant is mostly inactive after 8 hours, paraxanthine could still be blocking adenosine up to 10 hours later.
