Flavonoids From Green Tea Help Prevent Cognitive Decline

Green tea has long been hailed as a cardio-protective beverage due to its ability to lower levels of oxidized LDL cholesterol, an established heart disease risk factor. It has also been shown to promote brain health because the active compound, EGCG (Epigallocatechin gallate) freely crosses the blood-brain barrier to provide antioxidant support and lower damaging levels of brain inflammation.

Researchers from Japan reporting in the American Journal of Clinical Nutrition demonstrate that regular green tea consumption lowers the risk of developing functional disabilities that lead to problems with daily chores and activities, such as bathing or dressing. Drinking up to five cups of green tea each day can lower the risk of developing functional disabilities as we age by nearly one half.

Prior studies have determined that consuming green tea lowers the risk of diseases associated with functional disability, such as osteoporosis, cognitive impairment and stroke. To date, no formal studies have been conducted to confirm the impact of green tea consumption on functional ability. Researchers from Tohoku University Graduate School of Medicine in Japan modeled this study to affirm the positive results associated in the past with drinking green tea.

To design this research work, scientists handed out questionnaires to nearly 14,000 respondents aged 65 or older. The participants answered questions about general diet, green tea consumption and lifestyle. After a period of five years, researchers were able to find a close inverse link between functional disability risk and the consumption of green tea. Higher intake of green tea was associated with a dramatically lower risk of functional disability in the group studied.

The research team concluded that nearly 13% of the participants consuming the lowest amount of green tea (one cup or less each day) developed moderate to severe degrees of functional disability. By contrast, only 7% of those consuming the highest amount of green tea (5 cups or more each day) were classified with any degree of functional decline. The highest level of green tea consumption was shown to cut the risk of functional and cognitive decline by close to one-half.

The researchers noted that those consuming five or more cups of green tea each day also ate more fruit and vegetables, consumed more fish, were less likely to smoke, had fewer strokes or heart attacks, and tended to have a higher level of education. Improved dietary and lifestyle considerations are synergistic factors that compliment green tea consumption and likely contribute to the positive results in this study. Health-minded individuals already follow strict dietary principles to maintain brain health and functional abilities. Drinking 5 or more cups of green tea each day are shown to boost the healthy benefits associated with proper nutrition and lifestyle.

Green Tea Boosts Metabolism to Aid Weight Loss

Green Tea Boosts Metabolism to Aid Weight Loss

Green tea (and its less refined cousin, white tea) has been a part of the ancient Chinese tradition for countless generations, in large part due to its rich endowment of bioactive catechins. Many studies over the past decade have shown that green tea is a powerful tool to improve metabolism in a way that is supportive of weight loss.

Scientists publishing in the Journal of Agricultural Food Chemistry demonstrate that it activates genes associated with fat burning while also helping to reduce absorption of fat from the digestive tract. Further evidence on the gene-altering activity of green tea is reported in the International Journal of Cardiology, as polyphenols from the drink lower free radical damage to help maintain telomere length in heart cells. Drinking several cups of green tea each day may hold the key to effective weight management and cardiac health.

Researchers from the Departments of Chemical Biology and Pharmacology and Toxicology at Rutgers University in New Jersey examined the effect of green tea supplementation on obese mice, known to exhibit similar metabolic characteristics to humans. The animals were broken into two groups and both were fed a traditional high fat/Western style diet. One group received water supplemented with the green tea bioactive catechin EGCG, while the second group acted as a non-supplemented control.

The study determined that EGCG supplementation significantly reduced body weight gain associated with increased fecal lipids and decreased blood glucose levels compared to those of the control group. Scientists further found that fatty liver incidence, associated liver damage and liver triglyceride levels were also decreased by the EGCG treatment. Treated animals also experienced improved insulin response as well as lowered C-reactive protein (CRP) and interlukin-6 (IL-6) levels, both strong indicators of systemic inflammation and immune response.

The study authors concluded “Our results demonstrate that the high fat/Western diet produces more severe symptoms of metabolic syndrome and that the EGCG treatment can alleviate these symptoms and body fat accumulation. The beneficial effects of EGCG are associated with decreased lipid absorption and reduced levels of inflammatory cytokines.” Green tea helps our cellular engines (mitochondria) to better metabolize calories more efficiently, providing a significant weight management tool.

Additionally, supporting research documents the effect of green tea catechins on extending the lifespan of heart muscle cells. Scientists found that EGCG supplementation exerted a potent antioxidant effect that lowered free radical damage to preserve telomere length and reduce heart cell death. Nutrition experts recommend two to four cups of fresh brewed green tea daily or an organically compounded and standardized EGCG supplement (300 to 500 mg daily) to assist weight management goals and improve cardiovascular health.

Green Tea Catechins Boost Weight Loss Efforts in Overweight Adults

Green Tea Catechins Boost Weight Loss Efforts in Overweight Adults

Reporting in the research journal Obesity, researchers continue to mount crucial evidence to support green tea as an agent in the war against overweight and obesity. Green tea (and its less refined cousin, white tea) is shown to slow weight gain and may be a key tool in the obesity epidemic impacting the health of millions of children and adults in western cultures.

Mice supplemented with the active compound found in green tea, Epigallocatechin-3-gallate (EGCG) were fed a high-fat diet and gained weight much slower than their control counterparts. The findings demonstrate the potent effect of the natural tea extract when coupled with a healthy, calorie-reduced diet that minimizes processed carbohydrate foods and hydrogenated fat sources.

Extensive scientific research has been performed on green tea and the potent EGCG extract. Most of this work has shown a direct link between green tea consumption and lowered risk of Alzheimer`s dementia, many digestive cancers, cardiovascular disease as well as being an aid in weight management. Green tea contains between 30 and 40 percent polyphenols that contribute to its myriad of health benefits. Common black tea contains between 3 and 10 percent polyphenols, as the leaves have been highly refined to remove the naturally occurring compounds.

Research leader Joshua Lambert, assistant professor of food science in agricultural sciences at Penn State University and his team determined to expand on prior research showing that green tea consumption promotes healthy body weight. The researchers used obese mice genetically predisposed to gain weight. The mice were broken into two groups; each fed a high fat diet. The test group was supplemented with EGCG in their drinking water for a period of six weeks.

The results showed that mice receiving the active EGCG component through supplementation, along with a high-fat diet, gained weight 45 percent more slowly than the control group of mice eating the same diet without EGCG. Lambert noted “Our results suggest that if you supplement with EGCG or green tea you gain weight more slowly.” Additionally, mice fed the green tea supplement showed a nearly 30 percent increase in lipid excretion, suggesting that the EGCG was limiting fat absorption by inhibiting pancreatic lipase. The study did not differentiate between caffeinated and caffeine-free green tea consumption, so caffeine sensitive individuals can attain similar results with non-caffeinated sources.

Researchers noted that green tea consumption did not appear to suppress appetite, an indicator that the weight reduction effect was due to inhibition of fat cell genesis. The authors concluded “Human data … shows that tea drinkers who only consume one or more cups a day will see effects on body weight compared to non-consumers.” Most nutritionists suggest 2 to 4 cups of green tea each day, or a standardized EGCG extract (500 mg to 1 gram daily) along with a calorically-balanced diet to achieve weight management success.

Green Tea Consumption Improves LDL Cholesterol Levels

Green Tea Consumption Improves LDL Cholesterol Levels

Green tea consumption has been shown to benefit many health issues ranging from help with weight management to cancer prevention and treatment. New research published in the British Journal of Nutrition explains that the natural extract from the Camellia sinensis plant has a powerful effect on cholesterol metabolism in the human body.

Most forward thinking health professionals now understand that dysfunction in the LDL cholesterol pathway lays the foundation for cardiovascular health problems, cancer and fatty liver disease. Regular green tea consumption is now shown to improve healthy LDL cholesterol function, enabling the fatty molecule to efficiently usher excess cholesterol from the body and improve risk factors for many chronic disease conditions.

In one of the first studies of its type, researchers performed DNA microarray analysis to examine the effect of the active compound found in green tea called epigallocatechin gallate (EGCG). Scientists specifically targeted the catechin to determine their effect on cholesterol metabolism in HepG2 hepatocytes. They determined that the expression levels of several genes related to cholesterol metabolism, including the LDL receptor, were changed by EGCG treatment.

EGCG was found to boost the function of the LDL receptor on liver cells. Researchers commented “This is very important as proper function of the LDL receptor enables your liver to “capture” circulating LDL and recycle it.”  In this study, green tea is shown to alter gene expression toward healthy LDL cholesterol metabolism by improving receptor acceptance by the liver. The liver displays an improved capacity to capture and filter LDL cholesterol for removal from the body.

In addition to the finding that green tea alters LDL cholesterol metabolism, ECGC was found to inhibit genes to reduce the production of Apolipoprotein B (ApoB). ApoB formation is required to initially form LDL molecules in the blood. Excess production of ApoB is a significant marker for chronic illnesses ranging from cardiovascular disease and heart attack to increased risk of cancer and dementia.

Green tea and the active compound EGCG are quickly ascending to nutritional “superstar” status. The Chinese have extolled its virtues for countless generations. Researchers now document the prowess of this nutrient by scientifically validating the direct impact exerted on our genetic structure to affect healthy cholesterol function and removal from the body. The healthy benefits of green tea are realized by drinking several fresh brewed cups of organically harvested leaves each day or supplementing with 250 to 500 mg of EGCG extract.

The Chinese have known the healing power of green tea for generations. Many believe that the unprocessed tea leaves can help to prevent or even cure many chronic diseases including heart disease, cancer and dementia. Volumes of scientific evidence now provide compelling proof that the active polyphenol found in green tea (EGCG) has the power to increase the number of regulatory immune support T-cells.

T-cells play a crucial role in the suppression of autoimmune diseases including the terminal condition ALS (Lou Gehrig`s disease). Research published in the journal Immunology Letters demonstrates that regular consumption of green tea can help your innate immune system to operate at peak efficiency to fight invading pathogens.

Autoimmune diseases occur as the result of an imbalance in the immune system that results in the body mounting an attack against itself. Immune T-cells are critical in providing a defensive shield that can protect against cancer proliferation and a host of diseases where the body recognizes healthy cells and organs as foreign. T-cells also help to control systemic inflammation and can dampen the inappropriate response to normal cells seen in autoimmune conditions.

Scientists conducting this study found that EGCG found in green tea was responsible for a significantly higher number and frequency of regulatory T-cells found in the spleen and lymph nodes, helping to control the immune response. They found that EGCG did not directly affect the genetic DNA, but did influence gene expression that determines how the genetic material is switched on or off as a response to food consumption. Epigenetic regulation is a rapidly emerging science that explains the extensive health benefits seen with a natural diet.

Emily Ho, associate professor and research author from the Oregon State University Department of Nutrition commented with reference to EGCG “This appears to be a natural, plant-derived compound that can affect the number of regulatory T-cells, and in the process improve immune function.” Researchers found a dual role for green tea polyphenols include boosting T-cell production and fighting cellular inflammation. Both mechanisms are critical in fighting conditions exacerbated by chronic inflammation such as cancer and heart disease as well as autoimmune disorders.

Studies that involve regular consumption of naturally occurring foods and extracts are rapidly mounting to explain the importance of the foods we eat on our genetic health. Genes are expressed immediately following each meal and directly influence the progression of disease and the prevention of most chronic conditions.

Researchers conducting this study concluded “Epigenetic regulation can be potentially exploited in generating suppressive regulatory T cells for therapeutic purposes, and is of significant clinical importance for the suppression of autoimmune diseases.” Although this study did not publish the dietary equivalent of green tea used to achieve their results, similar studies have recommended consuming 2 to 4 cups of green tea daily or 500 mg of a standardized EGCG extract for optimal health benefits.

Natural Flavonoids Lower Risk of Developing Diabetes

Natural Flavonoids Lower Risk of Developing Diabetes

New research published in the Journal of Nutrition provides evidence that potent epicatechin flavonoids from extracts of green tea and cocoa lower the destructive effects of high blood sugar. This can effectively prevent damage that ravages the major organs and especially the coronary arteries lining the heart muscle. Diabetes is a disease that is growing at an epidemic rate and decreases life expectancy by as much as eight years.

Death occurs as a result of complications from multiple chronic conditions. Scientists found that epicatechin flavonoids inhibit the cellular damage caused by rising blood sugar levels and can prevent damage to the heart and liver. Regular supplementation can improve life expectancy by halting organ damage leading to chronic illness.

This body of research was conducted using five-week old diabetic mice known to present similar metabolic characteristics to humans. Mice were provided drinking water containing .25% epicatechin flavonoids for a period of 15 weeks. This group was compared with lean mice acting as a control. At the end of the study, half of the non-diabetic control mice had died compared with only 8.4% of the diabetic mice provided the epicatechin-supplemented drink. Both groups received the same diet and there was no difference in body weight as the study concluded.

Treatment with the epicatechin-infused water resulted in a significant reduction in deterioration of the aortic vessel of the heart and the liver. Additionally less fat was found to accumulate in the liver of the treated mice, an important factor known to cause progression of metabolic diseases including diabetes and lipid abnormalities. One of the most striking findings in the supplemented animals was a reduced level of systemic inflammation caused by oxidized LDL cholesterol and insulin-like growth factor-1 (IGF-1).

Many prior studies have demonstrated that sustained high levels of IGF-1 in the circulating blood are consistent with chronic disease and shortened life span. Because of the effect exerted by epicatechin compounds extracted from green tea and cocoa products, the study authors determined that the data derived “further suggests that epicatechin may be a food-derived, anti-aging compound given the important role of IGF-1 in regulating the life span of organisms.”

The potent health-inducing nature of green tea has been in evidence for more than 5,000 years as countless Asian generations have cultivated the plant for medicinal purposes. Nutrition advisors recommend taking 2 to 4 cups of fresh brewed green tea each day or supplementing with 250 to 500 mg of the EGCG active compound found in green tea to lower disease risk and increase healthy lifespan.

Compelling evidence presented in the journal Nutrition Research makes the firm connection between green tea consumption, lowered body weight and reduced levels of dangerous belly fat. Drinking between 5 and 8 cups of green tea each day was shown to lower body weight by 5.6% and decrease abdominal fat stores by 17.8% over a period of 8 weeks.

Green tea consumption has long been associated with lowered risk of cancer, metabolic syndrome and heart disease. This research provides compelling evidence that green tea boosts metabolism to target fat stores and assists weight loss efforts.

Green tea extracts have been researched extensively over the past decade and are shown to dramatically lower the risk of Alzheimer`s disease and dementias, cardiovascular disease and many forms of cancer. Additional studies have shown that the polyphenols in green tea are a significant factor in improved oral health and can provide necessary support for weight management and control. Green tea is composed of four primary polyphenols (epigallocatechin gallate (EGCG), epigallocatechin, epicatechin gallate, and epicatechin) that are shown to influence genetic signaling and metabolic rate.

The study was conducted by Polish researchers and used an animal model to determine weight loss and fat accumulation characteristics. The researchers also analyzed cardiovascular risk factors and atherogenesis over an 8 week period. The animals were fed a high fat diet and drank green tea made from either a 1.1% or 2% extract of the active phenolic compound. The results indicate that body weight and fat reduction are dose dependent with maximum results (5.6% lower body weight, 17.8% fat reduction) achieved with the 2% extract.

Green Tea Improves Arterial Elasticity and Reduces Cardiovascular Risks

Researchers also found that both concentrations of green tea extract reduced atherogenesis (initial loss of coronary artery elasticity leading to artery hardening and future heart disease) by 14.3% compared to non-supplemented subjects. The study authors did not determine the mechanism for cardiovascular risk reduction. Prior research has shown that the potent antioxidant content of green tea is responsible for significantly lowered levels of oxidized LDL cholesterol and increased particle size that are consistent with reduced heart disease risk.

This study used the equivalent of 5 to 8 cups of green tea consumed each day to achieve optimal weight management, fat reduction and cardiovascular risk reversal. Researchers found that the green tea concentration is important to achieve optimal weight lowering results. Drink 6 cups of fresh brewed, non-fluoridated green tea daily (or take a standardized green tea extract supplement) to help prevent coronary artery disease, assist weight loss and boost fat reduction efforts.
