I see people that drink 3-4 cups per day that get a massive headache if they don't have their daily coffee due to caffeine withdrawal.  I choose to avoid this addiction by only drinking 1 cup per day max.  I drink various teas like green, oolong, black, and white teas at other times, which are much lower in caffeine.  Or I like to use rooibos or other herbal teas many times which have no caffeine at all.
It’s enough to make a tea drinker buy an espresso machine. In a new study scientists in Germany report they were able to modify a common age-related defect in the hearts of mice with doses of caffeine equivalent to four to five cups of coffee a day for a human. The paper—the latest addition to a growing body of research that supports the health benefits of drinking coffee—describes how the molecular action of caffeine appears to enhance the function of heart cells and protect them from damage.
Poole notes that the analysis included a number of different studies, each with different designs, and not all of them may have adjusted for potential confounding effects that could skew the connection between coffee and health outcomes. Coffee drinkers, for example, also tend to smoke more than non-drinkers, and smoking has an effect on early death, heart disease and certain cancers.
In a research, a few individuals received a dose of 150 milligrams of caffeine each, about as much consisted of a cup of coffee. The researchers noticed a significant surge in their brain activity. The researchers, also, noted that the reaction times, as well as memory skills of the caffeinated individual improved dramatically compared to the control group that received an ordinary placebo. To be specific, they didn’t indicate any increase whatsoever as far as brain activity is concerned.
From health bloggers to celebs (hey, Jennifer Aniston), it seems like everyone is hopping on the collagen bandwagon this year—adding it to smoothies, cooked meals, and... you guessed it... coffee. If you’re not on board yet, don't believe everything you hear about collagen—sprinkling it into a smoothie probably won't make you look 30 years younger.
If you consider the “health” of your coffee as more than just what you’re putting in your body, but also how your coffee beans are grown, picked, and get to you, Swinney suggests you’re taking your coffee habit to a more beneficial level—not only for yourself, but for the world. “Drink clean and with a conscience. Choose fair trade or coffee with other certifications that help third-world farmers improve their living conditions. Give some thought to the packaging involved in single-serve coffee—it requires much more packaging and contains a larger carbon footprint for getting to the store.”

When a group of volunteers received a dose of 100 milligrams (mg) of caffeine, about as much contained in a single cup of coffee, Austrian researchers found a surge in the volunteers’ brain activity, measured by functional magnetic resonance imagery (fMRI), as they performed a memory task. The researchers noted that the memory skills and reaction times of the caffeinated volunteers were also improved when compared to the control group who received a placebo and showed no increase in brain activity.
The popularity of the Bulletproof Diet is undeniable. But what started the craze was the world-famous Bulletproof Coffee. By simply adding grass-fed butter to black coffee, you will get a nice brain-boosting buzz — as well as all the health benefits of grass-fed butter. Try blending the coffee with a handheld blender or latte frother if you are stuck with globs of butter on top of your coffee.
So how much java is too much? It's wise to stick to no more than 3 to 4 cups per day. Certain groups, such as people with hypertension and the elderly, may be more susceptible to the adverse effects of caffeine. Pregnant and breast-feeding women will want to limit intake to a maximum of 200 to 300 milligrams a day of caffeine (the amount in 2 to 3 cups of coffee). The American Congress of Obstetricians and Gynecologists recommends that pregnant women cap caffeine consumption at 200 milligrams a day.
In fact, according to a 2005 study conducted by researchers at the University of Scranton, coffee is the number one source of antioxidants in the human diet—yes, even over wine and tea. Aside from the caffeine giving you an early-morning energy buzz, those high levels of antioxidants can help protect your body from damage caused by free radicals, as well as fight off disease.

Cinnamon actually comes from the bark of a tropical evergreen called the Cinnamomum tree, and it has one of the highest antioxidant contents of any spice, according to research from the Journal of Agricultural and Food Chemistry. It’s been known to reduce inflammation, help lower sugar and triglyceride levels in the blood, soothe nausea, and aid in fat burning. The antiviral and antibacterial properties in the spice are also said to boost your immune system (and ward off colds.) It’s also packed with manganese, iron, calcium.

Studies show that coffee boasts of more antioxidant activity compared to the two antioxidant superstars; cocoa, and tea. In fact, a wide range of detailed lab analysis carried out over the years has identified over 1,000 antioxidants in coffee beans – unprocessed at that. Interestingly, hundreds of more antioxidants come up on roasting the beans. What’s more, a 2012 research labeled coffee as one of the core dietary antioxidants source readily available today.

You might think that nonfat, sugar-free vanilla syrup is a healthy choice, but low-calorie doesn’t always translate to health benefits. Swinney suggests weaning yourself off sweeteners completely if you can, but if you can’t, be super picky about the additives you’re putting into your brew. “Pick organic cream to whiten your coffee or make your own packaging-free alternative milk from oats or nuts. Creamers often have artificial flavors, sweeteners, and other additives, so you’re better off using organic milk or cream plus organic brown sugar,” she says.
