When you’ve ordered a latte or a cappuccino at Starbucks, you’ve probably watched as the barista wipes down the steamer before whipping up a new cup. This is meant to fight bacteria, but you may be getting something extra in your drink that you probably don’t want. “What you don’t realize is that sanitizing solution ends up in your frothed milk! It’s not a ton, but it is there—a small amount on that wand for every frothed carafe! So avoiding lattes is a good choice if that concerns you,” Immer says. Or just prepare yours at home to make sure you’re not getting more than you bargained for. This is the healthiest coffee you can drink.
If you are already a coffee drinker, it should be reassuring that after decades of research, no strong link can be found between coffee intake and cancer and, to the contrary, a number of health benefits seem to accompany coffee consumption. But, I’m not sure the evidence is powerful enough to recommend an increase in your daily habit. One reason is that we don’t know for sure that coffee consumption actually caused the health benefits observed in these studies. Some other, unmeasured factor could be responsible. Another reason is that the overall effect was small. And, it’s worth noting that some people are quite sensitive to the side effects of coffee.
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.
If you like your coffee on the sweeter side, swap out those artificial vanilla and hazelnut creamers and syrups for a naturally tropical taste by adding a tablespoon of coconut oil. And while coconut oil might not be the “cure-all” it’s made out to be, adding it to your coffee may have a few health benefits, from contributing to weight loss to possibly preventing Alzheimer’s disease. While these health claims are still under investigation, we think it's worth adding it to your coffee for the flavor alone. The creaminess is crazy.
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).
Here's what you should know: Collagen is the protein-rich connective material between tissue and bones (so, yup, veg-heads, you’ll have to sit this one out). It comes in a powder form, so you can stir it into pretty much anything to get a major protein boost that will help you kick-start your day. There’s also some preliminary evidence it can help keep your skin hydrated, improve alcohol-induced liver damage, and support joint health. Look for a brand that doesn't change the flavor, like Further Food Collagen Peptides, so you aren't scrunching up your nose at every sip.
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.
Men who drink coffee may be at a lower risk of developing aggressive prostate cancer. In addition, new research from the Harvard School of Public Health suggests that drinking four or more cups of coffee daily decreased the risk of endometrial cancer in women by 25 percent as compared to women who drank less than one cup a day. Researchers have also found ties between regular coffee drinking and lower rates of liver, colon, breast, and rectal cancers.
According to Jill Weisenberger, MS, RDN, CDE, one of the easiest ways to make sure your coffee is brewed in a healthy way is to consider how you’re filtering it. Those reusable filters might be tempting (and sure, provide less waste), but using recyclable paper filters has an added bonus for your nutrition. “Filtering coffee with paper removes two compounds, cafestol and kahweol, that raise both total and LDL cholesterol levels,” she explains. Here’s how coffee can help you learn.
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.
In 2005, Hu's team reviewed nine studies on coffee and type 2 diabetes. Of more than 193,000 people, those who said they drank more than six or seven cups daily were 35% less likely to have type 2 diabetes than people who drank fewer than two cups daily. There was a smaller perk -- a 28% lower risk -- for people who drank 4-6 cups a day. The findings held regardless of sex, weight, or geographic location (U.S. or Europe).
In fact, coffee shows more antioxidant activity than green tea and cocoa, two antioxidant superstars. Scientists have identified approximately 1,000 antioxidants in unprocessed coffee beans, and hundreds more develop during the roasting process. Numerous studies have cited coffee as a major — and in some cases, the primary — dietary source of antioxidants for its subjects.
We’ve been conditioned to believe that caffeine is dehydrating, one of the primary reasons why fitness experts recommend nixing coffee pre- and post-workout. However, recent research suggests that moderate caffeine consumption — up to about 500 mg, or about five cups per day — doesn’t dehydrate exercisers enough to interfere with their workout. In addition, coffee helps battle fatigue, enabling you to exercise longer.
