How Much Coffee Should You Drink?
Science tells us that generally, the more coffee you drink, the more the health benefits increase, especially relative to several major diseases. However, the downside is caffeine overload. Caffeine, from coffee or any other source, can increase nervousness, anxiety, jitters and restlessness.
It is important to note that each individual must take responsibility for their own wellness and consult their doctor if they have specific health questions. If you have a known heart condition, please discuss any change in coffee consumption with your doctor before increasing your intake of coffee.
Most studies on the health benefits of coffee focus on 3-5 cups of brewed coffee a day. However, certain health benefits increase significantly the more coffee you drink, up to 8-10 cups, although we are not recommending you drink that much coffee.
Drinking 3-5 cups per day has been found to lower the risk of Alzheimer’s disease by 65%.
Men who drink 6 or more cups of coffee daily had a 60% lower risk of developing prostate cancer.
Drinking 1-4 cups daily decreased the risk of Parkinson’s by 47%, whereas 5 or more cups decreased the risk by 60%.
Drinking 4-5 cups per day was associated with a 12% decrease risk of stroke, whereas with 6 or more cups per day was associated with a 23% decrease risk.
Drinking 1 cup daily lowered the risk of dying from liver cirrhosis by 23%, whereas 4 cups daily lowered the risk of cirrhosis by 84%.
Drinking 3-4 cups per day was associated with a 25% lower risk of developing diabetes. Every additional cup of coffee, up to 6-8 per day, was associated with a 5-10% risk of developing type 2 diabetes (up to 67%).
However, the downside of increased coffee consumption can be caffeine overload.
If you have been diagnosed with hypertension, you should not increase your caffeine consumption without first speaking to your doctor, since findings show progressively larger blood pressure responses to caffeine in persons with increasing risk of hypertension.
Some people are fast metabolizers of caffeine, and some are slow metabolizers. Your body knows how much caffeine you can tolerate. So, listen to your body. If you start to feel that jittery feeling, you have likely reached your body’s threshold for caffeine.
Scientific evidence indicates that for the general population of healthy adults, moderate caffeine intake is not associated with commonly cited adverse effects. Acceptable caffeine levels for most adults with no major health issues: 4 mg per body X weight: 400 mg per day should be the max (4-5 cups of brewed coffee)
While the health benefits are linearly correlated with the amount of coffee drunk, it is best not to exceed 5-6 cups, since high amounts of caffeine may be detrimental.
At Purity our recommendation is not necessarily MORE coffee– it’s BETTER coffee. Better coffee means lower toxins and less caffeine to get higher health benefits. We aspire to provide consumers with the highest level of health benefits for the lowest amount of liquid volume.
Healthy Coffee in Your Hands
Our quest thus far has led us to develop the most health-consciously crafted pure coffee that we have yet encountered. There are things you can do at home to help your coffee taste great and be as healthy as possible. These strategies, including the way you store and prepare your coffee, as well as the amount of coffee you drink, will help keep a focus on your health.
Healthy Practices at Home
- Start with pure water. If you would like more details, please visit: The Specialty Coffee Association of America’s Water Standard.
- Only grind the amount of coffee that you need, and brew within 15 minutes of grinding. Match the grind size to your brewing method, and try starting with this brew ratio and please adjust to taste:
- 3.75 oz. coffee to ½ gallon (64 fl. oz.) pure water
- 14 grams coffee per 235 ml pure water (about 0.5 oz. coffee per 8 fl. oz. water)
In the coming months Purity will be studying the effects of different grind sizes and brew methods on extraction of key health-related compounds in the coffee. We look forward to sharing the results with you.
- Use a chemical-free paper filter, if cholesterol is a concern of yours. Studies have shown that diterpenes in the coffee oils may increase LDL cholesterol (but may also have health benefits). Paper filters help trap them.
- Don’t let your coffee stew for hours on a hot plate, since continued heating changes the chemical composition of the coffee—and not for the better. Simply make the amount of coffee you intend to consume immediately, or put it in a flask that will keep it hot without re-heating it.
- Please don’t ever microwave your coffee. There are over 1000 compounds in just one cup, many of which are beneficial to your health. Microwaving coffee may have negative effects on some of these compounds.
- If your goal is to maximize the health benefits of your coffee experience, you should avoid artificial sweeteners and other additives, including sugar.
