Caffeine jump-starts your day and puts a bounce in your step. It can help you focus, improve your mood and maybe even help you live longer.
But how much is too much?
Caffeine, a natural stimulant, can be found in a variety of foods, such as coffee beans, tea leaves, cacao beans, guarana berries and yerba maté leaves. It also can be synthetically created and added to beverages such as soda and energy drinks. Research shows that about 90% of U.S. adults consume some form of caffeine every day.
One of the most popular ways people consume it is through coffee. Because of that, most caffeine research centers around this drink, said Dr. Greg Marcus, associate chief of cardiology for research and a professor of medicine at the University of California, San Francisco.
Full disclosure, I love coffee and coffee drinks like latte’s and cappucino. I drink more than one cup every day of my life.
If you need another reason to start the day drinking a cup of joe, a recent study by Johns Hopkins Medicine researchers has revealed that consuming at least one cup of coffee a day may reduce the risk of acute kidney injury (AKI) when compared to those who do not drink coffee.
“We already know that drinking coffee on a regular basis has been associated with the prevention of chronic and degenerative diseases including type 2 diabetes, cardiovascular disease and liver disease,” says study corresponding author Chirag Parikh, M.D., Ph.D., director of the Division of Nephrology and professor of medicine at the Johns Hopkins University School of Medicine. “We can now add a possible reduction in AKI risk to the growing list of health benefits for caffeine.”
Good news for those of us who can’t face the day without their morning flat white: a long-term study has revealed drinking higher amounts of coffee may make you less likely to develop Alzheimer’s disease.
As part of the Australian Imaging, Biomarkers and Lifestyle Study of ageing, researchers from Edith Cowan University (ECU) investigated whether coffee intake affected the rate of cognitive decline of more than 200 Australians over a decade.
Lead investigator Dr. Samantha Gardener said results showed an association between coffee and several important markers related to Alzheimer’s disease.
“We found participants with no memory impairments and with higher coffee consumption at the start of the study had lower risk of transitioning to mild cognitive impairment — which often precedes Alzheimer’s disease — or developing Alzheimer’s disease over the course of the study,” she said.
Conducted in partnership with the SAHMRI, the team found that people with high blood pressure, angina, and arrythmia were more likely to drink less coffee, decaffeinated coffee or avoid coffee altogether compared to those without such symptoms, and that this was based on genetics.
Milk chocolate is a consumer favorite worldwide, prized for its sweet flavor and creamy texture. This confection can be found in all types of treats, but it isn’t exactly health food. In contrast, dark chocolate has high levels of phenolic compounds, which can provide antioxidant health benefits, but it is also a harder, more bitter chocolate. Today, researchers report a new way to combine milk chocolate with waste peanut skins and other wastes to boost its antioxidant properties.
The researchers presented their results today at the American Chemical Society (ACS) Fall 2020 Virtual Meeting & Expo. ACS held the meeting through Thursday. It features more than 6,000 presentations on a wide range of science topics.
“The idea for this project began with testing different types of agricultural waste for bioactivity, particularly peanut skins,” says Lisa Dean, Ph.D., the project’s principal investigator. “Our initial goal was to extract phenolics from the skins and find a way to mix them with food.”
When manufacturers roast and process peanuts to make peanut butter, candy and other products, they toss aside the papery red skins that encase the legume inside its shell. Thousands of tons of peanut skins are discarded each year, but since they contain 15% phenolic compounds by weight, they’re a potential goldmine of antioxidant bioactivity. Not only do antioxidants provide anti-inflammatory health benefits, they also help keep food products from spoiling.
Eat less; move more; live longer is still the mantra here. We want to live as long as possible and also have a fully functioning brain all the way. I consider exercise to be one of the keys, but certainly diet plays a part, too.
Tufts Food & Nutrition Letter says that the science of whether some dietary choices can be considered brain food or not continues to unfold.
Given long time-frames of conditions such as Alzheimer’s disease and other dementias, it’s challenging to prove any cause and effect relationship between specific foods and brain health. Most such associations are drawn from observational studies, in which people who eat more or less of a certain food are assessed over time for cognitive changes.
It’s obviously difficult to feed a group of study participants lots of, say, blueberries for several years in order to test their brain health at the end; that’s why clinical trials of so-called brain foods have largely depended on animal tests.
Nonetheless, some foods tend to stand out from the pages and pages of research results as most likely being protective for brain health.
Foods That Promote Brain Function
Brain foods typically contain one or more nutrients that scientists believe have positive effects on the brain and/or the cardiovascular system, which in turn affects the brain. These foods include: Continue reading →
As a senior citizen coffee drinker who also has serious concerns about possible cognitive impairment, I was pleased to run across this study by Rutgers scientists.
Rutgers scientists have found a compound in coffee that may team up with caffeine to fight Parkinson’s disease and Lewy body dementia – two progressive and currently incurable diseases associated with brain degeneration.
The discovery, recently published in the Proceedings of the National Academy of Sciences, suggests these two compounds combined may become a therapeutic option to slow brain degeneration.
Mouradian said further research is needed to determine the proper amounts and ratio of EHT and caffeine required for the protective effect in people. NeuroscienceNews.com image is in the public domain.
Lead author M. Maral Mouradian, director of the Rutgers Robert Wood Johnson Medical School Institute for Neurological Therapeutics and William Dow Lovett Professor of Neurology, said prior research has shown that drinking coffee may reduce the risk of developing Parkinson’s disease. While caffeine has traditionally been credited as coffee’s special protective agent, coffee beans contain more than a thousand other compounds that are less well known. Continue reading →
I am guilty of being a coffee lover. I am so bad that when I see someone on TV carrying a cardboard cup of the brew, I am tempted to make some for myself. So, the following was good news for me.
Scientists have now proved that drinking certain types of coffee can be beneficial to brain health, but how does this popular brew support cognitive function? A new study identifies some of the mechanisms that allow coffee to keep mental decline at bay.
According to data from the Harvard T.H. Chan School of Public Health in Boston, MA, about 54 percent of all adults in the United States drink coffee on a daily basis.
While drinking coffee can bring both benefits and risks for a person’s health, a 2016 study from the University of Ulster in Coleraine, United Kingdom, concluded that the health benefits of moderate coffee consumption “clearly outweigh” the potential risks.
Apparently, Saturday, September 29 was National Coffee Day. I missed it.
I’ve touted the benefits of coffee and caffeine in past articles and blog posts (Please see Coffee, Caffeine, and Exercise, among others). Here’s an informative article from The Ladders’ Meredith Lepore. Read it with your daily cup of java.
It seems like every day there is a new study telling us either that coffee is slowly killing us, making us healthier, making us smarter, making us dumber, helping us grow wings, etc., However there are a number of studies that have come out recently that reveal some very interesting facts about your daily cup of joe. In honor of National Coffee Day, this Saturday, check out these 7 facts about coffee.
It can make everyone you work with so much more appealing
A recent study that appears in the Journal of Psychopharmacology finds that if you have coffee…
I am a coffee drinker and always happy to learn of positive effects to be gleaned from drinking it. As a matter of fact, I pretty much concentrate on decaf, though, because I don’t like to introduce any foreign chemicals into my system if I can help it. Also, I read an article about caffeine withdrawal symptoms that scared me.
Summary: A new study reports caffeine concentration, the equivalent of four cups of coffee, can promote the movement of a regulatory protein into mitochondria. This can enhance mitochondrial function and protect heart cells from damage.
They found that caffeine induced the movement of p27 into mitochondria, setting off this beneficial chain of events, and did so at a concentration that is reached in humans by drinking four cups of coffee. NeuroscienceNews.com image is in the public domain.
Caffeine consumption has been associated with lower risks for multiple diseases, including type II diabetes, heart disease, and stroke, but the mechanism underlying these protective effects has been unclear. A new study now shows that caffeine promotes the movement of a regulatory protein into mitochondria, enhancing their function and protecting cardiovascular cells from damage. Continue reading →
A couple of things to lay out before we start here. First, I don’t drink coffee with caffeine as I try to keep drugs of any kind out of my system. Second, I am a regular bicycle rider and always on the lookout for new sources of energy.
The other morning I had a new situation. I had a date for early afternoon to attend a play. In addition, we had reservations for brunch at noon. From this schedule, I was not going to have a lot of time to get in a bike ride. So, I thought I would rise at first light and take out the bike for a ride ahead of walking the dog and my social schedule for the day.
Normally, I start the day with what I call my rocket fuel. It is a smoothie that contains all my vitamins. You can read about it in A super breakfast smoothie.
On the morning in question, my reservation about my smoothie was that it takes 15 minutes to make and another 15 minutes to drink. I didn’t want to spend 30 minutes doing that. I wanted to be riding my bike. On the other hand I was concerned that having just awakened from a night’s sleep, my energy reserves were low. I sure didn’t want to black out. I hadn’t eaten in over nine hours.
So, what to do instead to give me a quick shot of energy. I like my coffee in the morning, but since it is decaf, I don’t expect a boost from it. Here is the beginning of a light bulb going off in my head. As recently as April, I got turned on to coconut oil as a wonderful source of nutrition. Check out Why should I try coconut oil? for more details. Since that time I have been using coconut oil in every way I could think of to cook in, shave with, etc. Coconut oil has a lot of healthy fat in it which provides energy. I decided to add a tablespoon of coconut oil to my coffee. Continue reading →
I confess I love coffee. I drink it every morning and after meals when I eat out. Mostly I consume decaf as I have read some horrifying studies on caffeine addiction and caffeine headaches. Also, I really don’t like to add chemicals to my system if I can help it. Here is an interesting study of the effect of caffeine and coffee on workouts from Medical Xpress.
Caffeine is one of the most researched substances reported to help athletes perform better and train longer and harder. As a result, professional and amateur sportspeople often take it as a performance-enhancing “ergogenic” aids for a wide range of activities. These include intermittent exercise such as football and racket sports, endurance exercise such as running and cycling, and resistance exercise such as weightlifting.
But while most research looks at the effects of pure caffeine consumed as tablets with water, in the real world most people get their caffeine from coffee, energy drinks or other products like special gels or chewing gum. So will drinking a cup of joe before your workout actually make a difference? The answer could depend as much on your genes as what kind of coffee you’re drinking.
Scientists think caffeine affects the body chemical adenosine, which normally promotes sleep and suppresses arousal. Caffeine ties up the receptors in the brain that detect adenosine and so makes it more alert. Continue reading →
I love my morning coffee. I also love a cup of cappuccino after dinner when dining out, so, clearly I have a dog in this fight.
Scientists have found that people who drink coffee appear to live longer.
Drinking coffee was associated with a lower risk of death due to heart disease, cancer, stroke, diabetes, and respiratory and kidney disease for African-Americans, Japanese-Americans, Latinos and whites.
People who consumed a cup of coffee a day were 12 percent less likely to die compared to those who didn’t drink coffee. This association was even stronger for those who drank two to three cups a day—18 percent reduced chance of death.
Lower mortality was present regardless of whether people drank regular or decaffeinated coffee, suggesting the association is not tied to caffeine, said Veronica W. Setiawan, lead author of the study and an associate professor of preventive medicine at the Keck School of Medicine of USC. Continue reading →
I am a great believer in the benefits of stair climbing. Check out my post 5 Reasons stair climbing is good for you to read much more about it. Here are some neat further benefits of this simple, but not necessarily easy, exercise that you can do in lots of places.
A midday jolt of caffeine isn’t as powerful as walking up and down some stairs, according to new research from the University of Georgia.
In a new study published in the journal Physiology and Behavior, researchers in the UGA College of Education found that 10 minutes of walking up and down stairs at a regular pace was more likely to make participants feel energized than ingesting 50 milligrams of caffeine-about the equivalent to the amount in a can of soda.
“We found, in both the caffeine and the placebo conditions, that there was not much change in how they felt,” said Patrick J. O’Connor, a professor in the department of kinesiology who co-authored the study with former graduate student Derek Randolph. “But with exercise they did feel more energetic and vigorous. It was a temporary feeling, felt immediately after the exercise, but with the 50 milligrams of caffeine, we didn’t get as big an effect.” Continue reading →
As a big fan of coffee in general and the mocha drink in particular, this study struck a positive chord with me.
Deep down, we always knew it, but science is proving that cocoa and caffeine are indeed the best marriage ever. Clarkson University researcher Ali Boolani recently completed a study that explores the powers of these two dark delights.
The assistant professor of physical therapy and physician assistant studies teamed up with colleagues at the University of Georgia to examine the “acute effects of brewed cocoa consumption on attention, motivation to perform cognitive work and feelings of anxiety, energy and fatigue.” Continue reading →
I found this on the web and thought it worth sharing. Regular readers know I am not a fan of soda drinks, sugared or chemicalled up. You can check out my Page – What’s Wrong With Soft Drinks? for details.
