Unroasted coffee beans don’t just impart bold, rich flavor. It also creates a compound that helps dial down production of stomach acid, according to research presented on March 21 at the spring meeting of the American Chemical Society. The discovery may explain why green coffee is gentler on the stomach than their lighter peers and could lead to a new generation of tummy-friendly coffees.
Even though several studies have found a cup-a-day habit imparts health benefits such as decreased risk of obesity, Alzheimer’s and colon cancer, many coffee lovers drink decaf or forgo the beverage altogether because it irritates the stomach or spurs heartburn. Previous work suggested that coffee made from steam-treated beans tamps down this gastric distress, a finding attributed to lower levels of caffeine and other compounds in these brews.
What are Kidney Stones?
Kidney Stones form when the urine becomes concentrated, which allows minerals in the urine to crystallize and stick together. Some stones can form from combinations of calcium and oxalate or phosphate — this is the most common type of stone. Infections can cause struvite stones. Uric acid stones can form in the urine of people who are dehydrated, those who eat a high protein diet, or those who have gout. Cystine stones, which are much less common, form in the urine of people who have a hereditary disorder that makes the kidneys excrete excessive amounts of certain amino acids.
Kidney Stones- How they are caused?
Kidney stones are formed when a very high content of calcium or other minerals get accumulated in the urinary tract and get clumped together, leading to painful stones. Symptoms include blood in urine, nausea, vomiting, fever, and swelling of the kidneys. The most common kidney stone is made up of calcium oxalate.
Green Coffee and Kidney Stones
A study has recently claimed that for each cup of green coffee consumed daily, women reduced the risk of having kidney stone by 8 percent. For men, the risk was as low as 14 percent. These findings however initially confused scientists, because they discovered that the level of calcium oxalate in urine had increased due to the consumption of green coffee which basically meant a higher risk of kidney stone.
Later in their studies, they were able to figure out that it was not just about the oxalate level but also about how it affects the crystal formation.
How Green Coffee prevents the formation of Kidney Stones?
After several studies conducted, contrary to popular belief, it has been determined that green coffee helps in preventing stone formation as well as assists in the further breakdown of crystals already formed. It appears that green coffee binds itself to calcium oxalate while crystallizing to adapt into a flat shape that makes its further breakdown even easier. Also, the oxalate content in the green coffee itself is increasingly less when compared to green tea variations, which makes green coffee consumption less harmful for kidney stone sufferers.
