In 2013, the journal Epidemiology and Prevention published a review of studies analyzing the correlation between coffee consumption and cardiovascular disease. Data from 36 different studies showed that people who drink three to five cups of coffee per day had a lower risk of heart disease than those who drink no coffee or more than five cups per day.
How it works: Antioxidants fight inflammation, an underlying cause of many chronic conditions, including arthritis, atherosclerosis and many types of cancer. They also neutralize free radicals, which occur naturally as a part of everyday metabolic functions, but which can cause oxidative stress that leads to chronic disease. In other words, antioxidants help keep us healthy at the micro-level by protecting our cells from damage. Finally, chlorogenic acid, an important antioxidant found almost exclusively in coffee, is also thought to help prevent cardiovascular disease.
Constituents in coffee can interfere with normal drug metabolism and detoxification in the liver, making it difficult to regulate the normal detoxification process in the liver. Another issue to be aware of with coffee intake is how certain medications such as levothyroxine (thyroid) as well as tricyclic antidepressants are poorly absorbed, making symptoms curiously worse for patients.
In addition to being pretty terrible for the environment, Immer says Keurig Coffee Makers also pose some potential health dangers. Not only do you expose yourself to plastic that’s been heated, but Keurigs tend to get dirty, fast. “The water tanks in a Keurig can never truly be flushed and cleaned. We are concerned about mold and bacteria growth in these tanks over time, much like commercial ice machines,” Immer says.
Regardless of what you might come across in health blogs and nutrition magazine, it’s true that coffee lowers the danger of liver cancer. Once again, a steady coffee consumption has been linked to a lower cirrhosis incidence more so alcoholic cirrhosis. Some studies have even indicated an inverse correlation between increased coffee drinking and a reduced risk of cirrhosis- 20% reduction for every cup consumed.
If you love the taste of coffee creamers, but don’t love all the processed sugar and added fat, try vanilla extract or vanilla bean for a hit of flavor. Add a few drops of pure extract to your pot of coffee or add a vanilla bean to your coffee grounds so the flavor infuses before you brew. (Note: The longer you keep the vanilla bean in your grounds, the stronger the flavor will be.)
For this part of the experiment, 22-month-old mice received caffeine—the daily equivalent of four to five cups of coffee in humans—in their drinking water for 10 days. That was sufficient to raise their mitochondrial respiration to the levels observed in six-month-old mice, according to the study. Analysis showed the old mice had roughly double the amount of p27 in their mitochondria after the 10 days of caffeine.
According to the web site myfoodapedia.gov -- part of the U.S. Department of Agriculture's Center for Nutrition Policy and Promotion -- a 6-ounce cup of black coffee contains just 7 calories. Add some half & half and you'll get 46 calories. If you favor a liquid nondairy creamer, that will set you back 48 calories. A teaspoon of sugar will add about 23 calories.
Increased coffee consumption may reduce risk of type 2 diabetes - the Harvard School of Public Health (HSPH) researchers gathered data from three studies. In these studies, the diets of the participants were evaluated using questionnaires every 4 years, with participants who reported having type 2 diabetes filling out additional questionnaires. In total, 7,269 study participants had type 2 diabetes.
Consider a complete elimination program and avoid all refined sugars, flours, caffeine, alcohol, dairy, gluten and any other addictive substance. By allowing certain triggers to stay in the diet the body stays on the vicious cycle of cravings and addictive behavior. Reset your biology by eliminating all these dietary triggers for inflammation and fatigue.
Other studies have tried to pinpoint exactly what in caffeine is helping to halt the onset of these diseases. A 2014 study (14) found that caffeine blocks various tau receptors (a protein that contributes to brain cell degeneration). Another study found that caffeinated coffee increased GCSF (15) - a substance greatly decreased in Alzheimer’s patients - levels in the bloodstream.
Feeling a little slow lately? All it might take to get your body back to working at a normal pace is a little coffee. A 2005 study from the Radiological Society of North America found it doesn’t take much—just a couple cups—to improve your reaction time, making you better at everything from noticing something scary like smoke in your home (and realizing you need to grab the fire extinguisher ASAP) to breaking your car for a stop sign.
