More recently, Australian researchers looked at 18 studies of nearly 458,000 people. They found a 7% drop in the odds of having type 2 diabetes for every additional cup of coffee drunk daily. There were similar risk reductions for decaf coffee drinkers and tea drinkers. But the researchers cautioned that data from some of the smaller studies they reviewed may be less reliable. So it's possible that they overestimated the strength of the link between heavy coffee drinking and diabetes.
First, you may have seen debate in the past about how coffee has some compounds in it that could have negative health effects such as small amounts of acrylamides or other possibly harmful compounds in brewed coffee. But, the good news is that coffee has such high concentrations of beneficial antioxidants, phenolic nutrients, chlorogenic acids, and other healthy compounds , that it more than counteracts any bad compounds.
Coffee is one of the world’s most popular beverages for a reason: It not only tastes good and gives you a serious jolt of energy, but it also has plenty of amazing, body-boosting benefits. Which, in all honestly, is a major bonus considering the fact that most people are simply pleased to have something to help them get through their morning meetings.
The study builds on earlier work in which the two scientists showed caffeine ramps up the functional capacity of the cells that line blood vessels. The drug does so by getting into cells and stoking the mitochondria, structures within the cells that burn oxygen as they turn glucose into energy.“Mitochondria are the powerhouses of the cells,” Haendeler says. One of the things they run on is a protein known as p27. As Haendeler and Altschmied discovered (and describe in the current paper), caffeine works its magic in the major types of heart cells by increasing the amount of p27 in their mitochondria.
Over the past decade, studies have found a link between coffee consumption and a lower risk of dementia. It’s thought that the drink’s high caffeine content might be responsible for the brain-boosting benefits. One small study of subjects who showed signs of memory problems found that, over a 2- to 4-year period, people with lower blood levels of caffeine were more likely to develop dementia than those with higher levels.

“For example, prior studies have suggested that variants in CYP1A2, (a gene) encoding the enzyme responsible for more than 95 percent of caffeine metabolism, may alter associations of coffee drinking with cardiovascular-related outcomes, with slower caffeine metabolizers having higher risk of developing hypertension (high blood pressure) or having a myocardial infarction (heart attack) relative to their non-drinking counterparts, whereas faster caffeine metabolizers who drink coffee are at no or lower risk of these outcomes.”
If you want a caffeine boost, but get too jittery or anxious with the two to four shots of espresso typically found in coffee drinks, order a tea latte with one shot of espresso. A typical shot of espresso contains around 64 milligrams of caffeine, while a cup of tea can range from 30 to 75 milligrams. Combining both can give you that energy boost without so much intensity.
Coffee lovers have happily embraced the headlines about the health perks of java: Aside from supplying a significant dose of antioxidants, a daily coffee habit may also help ward off a host of ailments, including type 2 diabetes, Parkinson's, and colon and breast cancers. To max out the benefits of your beloved cup of joe, give these six tips a whirl. You might find you enjoy your a.m. ritual even more.
Historically, it was first recorded as a drink just over 500 years ago, beginning on the Arabian peninsula, but there is a speculation that its use as a stimulating beverage stretches back more than 1,000 years in various ancient and indigenous cultures. Now, it is consumed in nearly every country of the world, and almost daily, even 5-6 times a day. While offices have larger machines, at home people often have single serve coffee makers which work best for the small requirements.
So how much coffee is healthy, and how much is too much? Two to three eight-ounce cups per day is considered moderate; heavy coffee drinkers consume four cups or more daily. Remember, the amount of caffeine per coffee beverage varies depending upon the preparation and style of beverage. Eight ounces of brewed coffee may contain as little as 80 to as much as 200 mg of caffeine per cup (an “average” cup probably contains about 100 mg).
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.

Cardamom is commonly used in Ayurvedic medicine, because it helps neutralize the stimulating effects of caffeine, but that’s not the only reason to add the spice to your java. A two-tablespoon serving has just 36 calories, is loaded with fiber, essential minerals, and cancer-fighting compounds; research published in the Asian Pacific Journal of Cancer Prevention found cardamom contains compounds with the potential to kill cancer cells and stunt new cancer cell growth. Cardamom has also been known to improve blood circulation in the body, help control cholesterol, cure dental diseases, and infections like gonorrhea. It’s even been said to cure impotency, erectile dysfunction, and premature ejaculation.
