News Editors via Natural News – What is green coffee? (Article republished from GreenMedInfo.com) What is green coffee? Before Dr. Oz featured it on his show this year, creating a global consumer feeding frenzy, it had already been investigated over thirty years ago for its possible liver-regenerating, detoxifying and anti-cancer properties.[i] [ii] [iii] (Article republished from GreenMedInfo.com) This is not to say that roasted coffee does not have its benefits too. In fact, research from the mid-80’s found that roasting coffee produces unique cancer-suppressing compounds not found in green coffee.[iv] Also, technically, the vast majority of studies performed on coffee’s health benefits are on the roasted form, as this is what most people consume globally. Research from the mid-80’s found that roasting coffee produces unique cancer-suppressing compounds not found in green coffee. There may also be unique mood-enhancing, even opiate-like properties in the roasted coffee bean associated with the fat-soluble compound known as cafestrol, which may not be found (or easily absorbed) in green coffee. But this “benefit” may also be a liability for those who may be prone to drinking too much, or feel they are prone to being “addicted” to habitual coffee consumption. But one thing that green coffee definitely has going for it is the fact that it is far higher in sheer antioxidant potential than roasted coffee, and most anything else we consume or drink on a daily basis. Some green coffee bean extracts score 2500 or higher on the ORAC scale, which stands for Oxygen Radical Absorbance Capacity – an abstract measurement of the potential for a substance to reduce oxidative stress. Compare this to an equal weight of blueberries, which scores 10, or Oranges which score 3. This is not to say that blueberries and oranges do not have their own unique health benefits beyond what the ORAC score can reveal – which they do! – but that the green coffee bean is simply a highly concentrated source of antioxidant compounds. And considering how stress, chemical exposures, dietary deficiencies and/or incompatibilities, all lead to increasing oxidative stress in the body (which is a cause of premature aging, cellular damage, and even increased risk for cancers) increasing antioxidant levels in our diet can make a world of difference. Keep in mind that green coffee really isn’t all that “new.” It is believed that cultivation of the coffee bean originated in the area of Arabia on the Red Sea over 900 years ago, and that at the time, the beans were not roasted but brewed in a manner quite similar to tea. [v] So, what are the likely health benefits of green coffee? Despite the present Oz-generated craze to identify green coffee consumption with weight loss, the primary finding is that it has beneficial blood pressure modulating properties. Green Coffee Lowers Blood Pressure Back in 2005, a study published in the journal Hypertension Research found that male volunteers with mild hypertension given various doses of a water-soluble green coffee bean extract (GCE) saw significant reductions , in a dose-related manner, in both diastolic and systolic blood pressure.[vi] The subjects received either 46 mg, 93 mg, or 185 mg of GCE once a day for 28 days. Another study performed in 2006 found similar blood pressure lowering results using 140 mg/day green coffee bean extract of chlorogenic acid . [vii] Finally, a study performed in 2007 found that green coffee is superior to roasted coffee in reducing blood pressure, due to its lower levels of hydroxyhydroquinone, a by-product of the roasting process.[viii] The ordinary coffee group experienced almost no effect. Green Coffee Reduces Weight and Body Mass Index, and May Improve Type 2 Diabetes In the most widely publicized study on green coffee, Dr. Joe Vinson of the University of Scranton lead a randomized, double-blind and placebo-controlled crossover study which found that the consumption of green coffee bean extract reduced weight in overweight subjects.[ix] Subjects received either a high dose green coffee extract (1050 mg), a lower dose (700 mg) or a placebo for six-weeks, followed by a two-week washout period to reduce any influence of preceding treatment. Primary measurements were body weight, body mass index, and percent body fat. Blood pressure and heart rate were also measured. The results were a significant reduction in observed body weight: “(-8.04± 2.31 kg), body mass index (-2.92 ± 0.85 kg/m(2)), and percent body fat (-4.44% ± 2.00%), as well as a small decrease in heart rate (-2.56 ± 2.85 beats per minute).” There we no significant changes to the diet over the course of the study, and impressively, body mass index for six subjects shifted from preobesity to the normal weight range. The study concluded: “The results are consistent with human and animal studies and a meta-analysis of the efficacy of green coffee extract in weight loss. The results suggest that GCA may be an effective nutraceutical in reducing weight in preobese adults, and may be an inexpensive means of preventing obesity in overweight adults.” Dr. Vinson believes that green coffee’s uniquely high concentration of chlorogenic acid relative to the roasted form may be responsible for some of its observed weight-loss promoting effects. Chlorogenic acid is known to increase the absorption of glucose, which offsets some of the insulin resistance and blood sugar elevations associated with type 2 diabetes. Indeed, there is a solid body of clinical literature linking chlorogenic acid to the well-known anti-diabetic properties of coffee. So, is green coffee a new “magic bullet,” or is it just another fad? We don’t know. But, relative to some of the pharmaceutical interventions used today to “treat” overweight and obesity, diabetes and high blood pressure, the research thus far indicates green coffee may make for a promising natural alternative.

From Coffee to Dark Chocolate, the Many Health Benefits of Polyphenols: ‘Dramatic Anti-Cancer Effects’

AHA Publisher — Thu, 21 Oct 2021 07:00:55 +0000

Lori Johnson via CBN News – This year marked the first-ever national Polyphenol Day, a day set aside to recognize one of nature’s healthiest nutrients. Polyphenols, found in certain plant foods are considered very good for the body because of the protection they provide from damage that often comes with aging. In addition to fighting the many negative effects of aging, research shows these compounds can also reduce the risk of heart disease and other leading causes of death. Dr. Steven Gundry, a leading cardiovascular surgeon who specializes in nutrition and the treatment of elderly patients, told CBN News he recommends a diet rich in polyphenols. “Some of these compounds are now recognized as having dramatic anti-cancer effects,” he said. “And I actually use the power of polyphenols in most of my clinic for the active treatment of people with cancer, metastatic cancer, who are inoperable.” In fact, Dr. Gundry pushed the designation of national Polyphenol Day to build interest and knowledge. He said people can find these compounds in their local grocery store if they know what to look for. He says many foods containing polyphenols can be found in the produce department or the frozen food section. “Right now blackberries and raspberries have the highest polyphenol content of any of the berries, that’s followed by strawberries,” he explained. “Traditionally we’ve always thought of blueberries as a great source of polyphenols, but blueberries have actually been bred for sugar content so now blueberries are a little bit down the scale of where you’d find polyphenols. The exception is if you find wild blueberries or tiny blueberries.” Dr. Gundry says when shopping, make sure to go to the aisle where olive oil can be found. It contains high amounts of polyphenols. However, since there are so many different brands, choosing the right olive oil can be confusing. “The more bitter olive oil, the kind that makes you cough, or kind of burns, that’s a sign of the polyphenol content,” he said. Believe it or not, Dr. Gundry says polyphenol-rich foods can be found in the candy aisle in the form of dark chocolate. Like olive oil, Dr. Gundry says the more bitter the better. That means choosing one with the highest percentage of cacao. “Extra dark chocolate has tons of polyphenols. But beware: milk chocolate, which is preferred by Americans, all the polyphenols have been taken out to make it taste good,” he said. Black coffee also does more than give you a morning pick-up, explains Dr. Gundy. “A fascinating study shows people who drink five or more cups of coffee per day have a very low incidence of Alzheimer’s or Parkinson’s,” he said. “And it turns out it’s the polyphenols that have that benefit.” Some, but not all, teas also score high. “And it really doesn’t matter whether it’s green tea or black tea, but herbal teas aren’t loaded with polyphenols,” he said. Dr. Gundry recommends using spices liberally because most of them, even ordinary black pepper, can help. “Sprinkle them on your salad, on your fish, your chicken,” he said. “You can get polyphenols every day without worrying about it.” By increasing the consumption of polyphenols in foods and beverages, spices, and supplements, research shows we can lower our risk of disease.
