Drinking moderate amounts of coffee – about three or four cups a day – is more likely to benefit our health than harm it, our latest research shows. This is important to know because around the world over two billion cups of coffee are consumed every day.
Earlier studies have suggested beneficial links between coffee drinking and liver disease. Our research group has an interest in liver conditions. As such, we had previously conducted two meta-analyses, one looking for links between coffee drinking and cirrhosis and another at coffee drinking and cancer of the liver. We found that there was a lower risk of both conditions in people who drank more coffee.
Most of the evidence, however, is from observational studies, which can only find probable associations but can’t prove cause and effect. To overcome these limitations, we plan to conduct a randomised controlled trial in patients with non-alcoholic fatty liver disease to see if coffee works as a treatment to reduce the risk of the disease progressing.
But before we can start giving coffee to patients, we needed to know whether coffee drinking had any recognised harms, so we decided to
Millions of groggy people this morning grubbed up an additional 5¢ to 20¢ for their Starbucks fix. No biggie. Most probably swiped or scanned and didn’t even notice it.
But for Starbucks, those nickels and dimes add up–especially since it is paying less for the beans while ringing up higher-priced lattes.
The cost of coffee on commodity markets–the green, unroasted beans, or “berries,” that are stripped off the branch–has been swooning, thanks primarily to a lot of rain and high temperatures in Brazil.
So, cheaper beans for them, higher prices for you–a simple and strong mix, with financial markets swirled just so and a light dash of marketing.
The Arabica empire said it hadn’t tinkered with prices on many of its drinks for about two years. It has “to balance the need to run our business profitably while continuing to provide value to loyal customers and to attract new customers,” spokeswoman Lisa Passe said in a statement. Translation: Sometimes we realize you’ll pay more.
Seeing the big dip in coffee bean prices this spring, Starbucks went ahead and locked in all the beans it will need for the rest of the year and about two-thirds of the beans it will need next year. “We expected coffee prices to come down, just given what we saw in the market,” Chief Financial Officer Scott Maw said during a conference call in late April. “We waited, we were patient, and when they came into our target range, we filled up our needs for the year.”
Hedging goes the other way, too: The recent dip in coffee prices meant that Starbucks was forced to buy some of the beans it brewed this spring at above-market rates because it had locked the price in months earlier, when it was higher.
Still, if the market pans out as Starbucks expects, coffee prices will tick up next year and the company will still be paying this year’s low rates. Meanwhile, it will keep plinking that extra 5¢ to 20¢ per cup into the profit sack (and the bonus pool for that savvy hedging team).
In short, Starbucks is raising prices for one very simple reason: because it can. ……….’
People just aren’t getting enough rest. With a Starbucks on almost every corner, people underestimate the importance of sufficient sleep and rely on a cup or two of coffee to make it throughout the day. In a new study, researchers have found yet again that getting the proper amount of sleep can keep you from developing poor cognitive function later in life.
The study conducted by the University of Warwick, published in PLOS ONE, involved about 4,000 men and over 4,800 women. Researchers observed the quantity versus quality of sleep in different age groups. For adults ages 50 to 64, getting the right amount of sleep was helpful in avoiding brain damage. Adults who slept more than the recommended six to eight hours of sleep showed signs of lower cognitive function. For older adults 65 years and up, the quality of sleep was more important than the quantity. Too much sleep was also noted to be damaging.
“Sleep is important for good health and mental wellbeing. Optimizing sleep at an older age may help to delay the decline in brain function seen with age, or indeed may slow or prevent the rapid decline that leads to dementia,” Francesco Cappuccio, a co-researcher, said in a press release.
If you feel groggy in the morning, it could be that you are getting too little sleep or too much sleep. The National Sleep Foundation says that seven to eight hours of sleep is sufficient, but based off of your age and how you feel, it can vary. Getting a lack of sleep can put you at risk for several chronic diseases such as diabetes, cardiovascular disease, obesity, and depression.
If you are having trouble getting a good night’s rest, the Centers for Disease Control and Prevention offers a few tips that can help you. Try going to bed and waking up around the same time every day. It is recommended one avoid large meals before going to bed and turn off lights and the television. Consistent trouble with sleep could be associated with sleep disorders such as insomnia, narcolepsy, restless leg syndrome, or sleep apnea.
People suffering with insomnia can’t get to sleep at night and tend to fall asleep during the day. Narcolepsy causes excessive daytime sleepiness. Restless leg syndrome causes pains in your legs, making it very difficult to go to sleep. Sleep apnea causes heavy breathing during the middle of your sleep and causes you to stop breathing for short periods. If you have any of these syndromes, you should seek treatment immediately.
