“Coffee consumption has been consistently linked with a lower risk of type 2 diabetes in cohort studies from across the world,” says epidemiologist Rob van Dam of the National University…
At typical intakes, caffeine doesn’t raise your risk of heart disease. But some methods of brewing coffee—regular or decaf—could harm your heart by raising your LDL (“bad”) cholesterol. Fortunately, that’s…
How much water do you need? “You’d think we’d have a one-sentence answer,” says Colleen Muñoz, assistant professor of health sciences at the University of Hartford. “But it’s much more…
Soft drinks, coffee, and tea aren’t the only sources of caffeine. The attention-boosting chemical is also found in chocolate drinks and candy, too. But the amounts can be pretty small.…
Tea is in. The average American drinks some 155 cups a year. That makes tea the country’s fourth most popular beverage, after water, soft drinks, and coffee.
There is no doubt that tea is an invigorating drink – probably due to how much caffeine is in tea (about half the caffeine of coffee).
And the national waistline would be far better off if we replaced some of that soda with tea (provided we sipped it with little or no sugar).
Most people rely on caffeine to stay alert. But researchers suggest that it may do far more—lowering the risk of Parkinson’s disease and gallstones, for example. Here’s what you may not know about the times that caffeine is good for you.

More than 80 percent of American adults consume caffeine regularly. That’s no surprise, what with a coffee shop seemingly on every corner and in every supermarket, and tiny $3 bottles of 5-hour Energy popping up like mushrooms wherever there’s a checkout counter. It turns out, though, that there is also caffeine in ice cream and frozen yogurt.
How does caffeine work in the body?
Caffeine works mainly by temporarily binding to adenosine receptors in the brain. That prevents adenosine, which is a natural sedative produced by the brain, from occupying those receptors and making us feel drowsy. Adenosine levels build up during waking hours and then drop as we sleep.
People who don’t use caffeine regularly and who haven’t developed a dependence on it “usually become significantly more alert and better able to perform cognitive and motor tasks – such as paying attention during boring tasks or typing – if they’re given the right dose of caffeine,” says Laura Juliano, a professor of psychology at American University in Washington, D.C.
“If it wasn’t on a caveman’s menu, it shouldn’t be on yours.” That’s the basic premise of a Paleo diet. The question remains, as it should for any diet—is Paleo healthy?
Maybe you’ve heard of the Nordic diet, the Mediterranean diet, and more recently, the gluten-free diet, but these are all very different from the primal diet known as Paleo.
But is the Paleo diet healthy?
According to the International Continence Society (ICS), incontinence is the “involuntary loss of urine that is a social or hygienic problem and is objectively demonstrable.” Urinary incontinence is most commonly a result of bladder dysfunction, sphincter dysfunction, or a combination of both. An estimated 30 to 40 percent of middle-aged women and 50 percent of older women experience urinary leakage.
The problem is less common in men, but does increase with age. Even so, older men experience severe urinary incontinence at only about half the rate of women. Despite the prevalence of this health problem, it is still a “don’t ask, don’t tell” issue.
“In our study of nurses, less than 50 percent of the women who had incontinence reported it to their doctors,” says Mary Townsend, an epidemiologist at Brigham and Women’s Hospital in Boston.
It is a sensitive issue, for sure, but what is the cause of urinary incontinence? Leaks are more common in women who are older, heavier, or smokers, and in those who have had more children, diabetes, or a hysterectomy.
“Beverage of champions: Chocolate milk gets an Olympic-style makeover,” reported the Washington Post in January after ads featuring U.S. Olympic athletes began popping up during the Sochi winter games. Olympic athletes have access to the best in exercise regimens and health and nutrition advice. If they drink chocolate milk post workout, should you?
When it comes to recovering from intense exercise, this classic childhood beverage has taken the spotlight.
In some studies, drinking chocolate milk immediately after a strenuous workout is one of the best ways to recover quickly—better than sugary sports drinks like Gatorade. The milk’s naturally occurring sugar (lactose) is half glucose, its protein speeds up glycogen synthesis in the body, and its electrolytes (like potassium and, to a lesser extent, sodium) help you rehydrate.
