You’re in your pajamas or sweats, and the coffee’s on. Without even trying, you’ve just done something positive, as coffee may protect you against developing both Alzheimer’s and Parkinson’s diseases. Though it’s certainly not a cure, a new study out of the Krembil Brain Institute investigated how certain components within coffee can decrease your risk of cognitive decline.
It turns out that the roasting process of coffee beans leads to higher quantities of a compound known as phenylindanes, which act as warriors against specific protein fragments common in Alzheimer’s and Parkinson’s. The other plus to the discovery is that phenylindanes are a natural compound, one from Mother Nature, and easy to extract for further research.
A hot cup of Joe isn’t for everyone, though, and many have turned to cold coffee because they find it less acidic, and want to avoid heartburn or gastrointestinal distress. The U.S. market grew 580 percent from 2011 to 2016 to cold-brew coffee preferences, which is a no-heat long-steeping method of preparation. A new study published in Scientific Reports shows that the pH levels of both hot- and cold-brew coffee are overall quite similar, ranging from 4.5 to 5.13 for all samples tested. So switching to a cold brew shouldn’t be a “silver bullet” to avoid stomach distress, cautions one of the authors of the study, says Megan Fuller, Ph.D.
Kids and caffeine: What are the risks?
Children are vulnerable to the effects of caffeine, and the American Academy of Pediatrics doesn’t want them ever touching the stuff. Or energy drinks. Because they weigh less than adults, when they do consume caffeine, its concentration in the body is higher per kilogram of body weight, and can cause headaches, dehydration, nervousness and difficulty sleeping or concentrating. Furthermore, its effects will last longer than the three to seven hours it takes for an adult to break down caffeine.
We shouldn’t really like coffee, as it’s bitter, but weirdly, reports show that the more sensitive you are to the bitter taste of coffee, the more of it you drink. By evolutionary logic, you would typically spit out something that was bitter and might harm you. But a new study of more than 400,000 men and women in the U.K. suggests that the positive reinforcement, namely the stimulant elicited by caffeine, negates the bitterness, and instead, triggers our reward center. We associate “good things with it.”
Coffee or tea, that’s a daily habit that you could feel good about.
