In Discussing his audiobook on caffeine with Terry Gross on NPR Last winter, Michael Pollan called caffeine “the enemy of good sleep” because it interferes with deep sleep. He confessed that after the daunting task of weaning himself from coffee, he was “sleeping like a teenager again.”
Dr. Willett, now 75, said, “You don’t have to consume zero to reduce the effect on sleep,” but he acknowledged that a person’s sensitivity to caffeine “probably increases with age.” How fast people metabolize caffeine also varies widely, with some people sleeping well after drinking caffeinated coffee at dinner, while others have trouble falling asleep after drinking coffee at lunch. is. But if you fall asleep easily after an evening coffee, it can hinder your ability to get enough deep sleep, says Mr. Pollan in his upcoming book, “This Is Your Mind on Plants.”
Dr. Willett said it is possible to develop a degree of tolerance to the effects of caffeine on sleep. My 75 year old brother, who is heavily addicted to caffeinated coffee, claims it has had no effect on him. However, gaining a tolerance to caffeine may outweigh its benefits if you want it to help you stay alert and focused while driving or taking a test.
Caffeine is one of over a thousand chemicals in coffee, not all of which are beneficial. Others with positive effects are polyphenols and antioxidants. Polyphenols may inhibit the growth of cancer cells and reduce the risk of type 2 diabetes; Antioxidants, which have anti-inflammatory effects, may combat both heart disease and cancer, the nation’s leading killers.
This by no means means that coffee is beneficial no matter how it is prepared. When brewed without a paper filter, as in French press, Norwegian steamed coffee, espresso or Turkish coffee, it contains oily chemicals called diterpenes that can raise artery-damaging LDL cholesterol. However, these chemicals are virtually absent in both filtered and instant coffee. Knowing I had a cholesterol problem, I dissected a coffee pod and found a paper filter on a plastic cup. Wow!
Also some people use to counter the potential health benefits of coffee, such as creams and sweet syrups, which can turn this calorie-free beverage into a calorie-rich dessert. “What people put in coffee can result in junk food with 500 to 600 calories,” Dr. Willett said. a 16-ounce Starbucks Mocha FrappuccinoFor example, it contains 51 grams of sugar, 15 grams of fat (10 of them saturated) and 370 calories.
With iced coffee season approaching, more people are likely to turn to cold-brew coffee. Now increasing in popularity, cold brew is due to the natural acidity and bitterness of counter coffee that occurs when boiling water is poured over the ground. cold brew is made by submerging the field in cold water for several hours, then filter the liquid through a paper filter to remove the ground and harmful diterpenes and keep to enjoy the flavor and caffeine. Cold brew can also be made from decaffeinated coffee.
Decaf is not entirely without health benefits. Like caffeinated coffee, the polyphenols in it have anti-inflammatory properties that may reduce the risk of type 2 diabetes and cancer.
