Does Green Tea Help The Prostate
Green tea is a terrific superfood. A Chinese proverb says that its better to be deprived of food for three days than tea for one.
Thats how the Ancient Chinese regarded this healthy food, and we can benefit a lot from embracing their wisdom.
Back then, people believed that a sip of green tea cures many ailments. And today those beliefs are backed by evidence and scientific research.
May Benefit Cognitive Health
Regularly consuming garlic and ginger or taking garlic and ginger supplements may help protect your brain and improve cognition.
Some population studies have suggested that consuming garlic may be particularly helpful for protecting against cognitive impairment in certain populations.
A 2019 population study that included 27,437 older Chinese people found that those who consumed garlic more frequently were less likely to experience cognitive impairment. They also lived longer than those who rarely consumed garlic (
- high cholesterol
- high blood sugar levels
A 2014 review of 22 high quality studies found that consuming garlic powder significantly reduced levels of total and LDL cholesterol, as well as fasting blood sugar and blood pressure levels .
Other studies have shown that garlic helps reduce blood pressure, blood sugar, and cholesterol, and that it helps prevent atherosclerosis, or the buildup of plaque in the arteries .
Studies have also linked ginger to heart health benefits.
A 2017 study including 4,628 participants found that consuming 1 gram of ginger daily decreased peoples risk of high blood pressure and coronary heart disease by 8% and 13%, respectively (
Summary
Studies show that ginger and garlic may help reduce heart disease risk factors like high blood pressure and high blood lipid levels and help protect against heart disease.

What Does Green Tea Do To The Prostate Gland
Studies focusing on EGCG show how that this antioxidant affects the prostate gland however, there are two functions in particular that are worth highlighting:
Erectile Dysfunction And Ginger Root
Erectile dysfunction, defined as the inability to achieve or maintain an erection sufficient to facilitate intercourse, is one of the most common problems that men face all over the world. This particular problem is not pleasant and it is quite psychologically troublesome for all men.
In some cases, erectile dysfunction is temporary, often a sign of extraordinary stress, and will resolve on its own spontaneously. In other cases, it is a long-term problem, which can also result from underlying medical conditions such as diabetes, cardiovascular diseases, Parkinsons disease, or multiple sclerosis.
Because erectile dysfunction can have a large negative impact on a mans quality of life, experts are looking for various ways to solve this problem and help men have proper sexual intercourse once again. Nowadays, there are a lot of medications that will help men treat the problem of erectile dysfunction.
Viagra is the best known medication for erectile dysfunction. Apart from medications, there are also a lot of natural remedies that help in getting rid of erectile dysfunction. Ginger root is thought to be one such remedy. However, people should first get to know as much as they can about the ginger root.

Green Tea & Prostate Cancer: Implications
Prostate cancer is typically a slow-growing cancer, Henning says. That makes it an ideal cancer to try diet interventions to slow it even more.
“Green tea is high in polyphenols and it’s convenient,” she says.
Other research has found that green tea may slow prostate cancer. An Italian study found that men who had a precursor to prostate cancer and drank green tea were less likely to get prostate cancer, Henning says.
Now, Henning is studying whether adding quercetin, an antioxidant found in apples and onions, to the green tea will ramp up its cancer-fighting ability.
Sumanta Pal, MD, assistant professor of medical oncology at the City of Hope Comprehensive Cancer Center in Duarte, Calif., reviewed the study findings for WebMD.
“Studies such as this are critical to confirm or support a plausible explanation for how green tea may work,” he says. More study is needed, however, before making any diet recommendations.
Benefits Of Tea For Prostate Ingredients
Each one of the ingredients has different benefits that can help the male body to function better.
- Holy Basil is an adaptogen that aids the body adapt to whatever situation that life throws at it
- Ginseng is also a powerful adaptogen
- Hawthorn Berries can help with vein structure and blood flow
- Saw Palmetto Berries can aid the function of the prostate making this a great tea for prostate health
- Ginger Root is anti-inflammatory and warming
- Molasses contains many vitamins and minerals while adding a bit of sweetness
- Ginkgo Leaves can help with blood flow and memory, but too much can cause headaches in some
Alone, any of these would be good for a single tea, but together they make a great combination for the man in your life.

It May Rev Up Your Metabolism Helping You Lose Weight
The phytonutrients in green tea may also help you lose weight and keep it off. A 2009 meta-analysis of studies in this area found that drinking catechin-rich green tea significantly reduced body weight . Furthermore, people who drank green tea were more likely to maintain a healthy weight after significant weight loss.
Green Tea & Breast Cancer
Other researchers reported that an extract from green tea, Polyphenon E, may help inhibit breast cancer by affecting substances called growth factors. Growth factors are involved in the signals that tell breast cancer to grow.
In earlier research, Katherine Crew, MD, assistant professor of medicine and epidemiology at Columbia University Medical Center in New York, had assigned 40 women already treated for breast cancer to take 400, 600, or 800 milligrams of the extract or to take a placebo twice daily for six months.
That was a study to examine any toxic effects of the extract. For the current study, she evaluated blood and urine samples from 34 of the women to see how the extract might work as a cancer fighter.
“We wanted to better understand the biological effects,” she says.
“After two months of Polyphenon E, there was a reduction in hepatocyte growth factor,” she says. This is one of the growth factors that affect breast cancer cell growth, spread, and invasion. That reduction declined and was not different from the placebo group at four months, however.
It’s still too early to recommend green tea extract as a way to prevent breast cancer, Crew says.

Why Are Coffee & Tea Bad For The Prostate
The prostate is a gland found in men that is responsible for the secretion of semen. As a man ages, this gland tends to become enlarged, causing pressure on parts of the urinary tract such as the urethra and bladder. As a result, you may experience urinary frequency combined with an inability to fully empty your bladder. A chronically enlarged prostate can also lead to incontinence, pain when urinating and infection. While coffee and tea don’t cause an enlarged prostate, they may make symptoms worse.

For men, living long enough means you are going to have problems with your prostate. While the prostate is typically a small, walnut-sized gland in young males, it undergoes two phases of growth later on in life which often result in urinary problems. The first phase of growth occurs during puberty and usually doubles the size of the gland, while the second phase of growth begins at around 25 and continues for the rest of your life leading to benign prostatic enlargement . More than 50 percent of men have BPH by the age of 60 and experience urinary difficulties. Although prescription medications are commonly used to treat BPH, herbal supplements may provide much needed relief during the initial stages of the condition. One such herbal solution is green tea.

Questions And Answers About Calcium
Calcium is a mineral that is needed for basic blood vessel, muscle, and nerve functioning, for sending signals from cell to cell, and for releasing hormones. It is the most common mineral in the body. The body stores calcium mainly in bone tissue.
The main sources of calcium are in foods and dietary supplements. About one-third of dietary calcium comes from milk and milk products like cheese and yogurt. Vegetable sources include Chinese cabbage, kale, and broccoli. Foods may have calcium added, such as fruit juices and drinks, tofu, and cereals.
Most research about calcium and prostate cancer risk has studied calcium in the diet and not calcium in supplements.
See the Laboratory/Animal/Preclinical Studies section of the health professional version of Prostate Cancer, Nutrition, and Dietary Supplements for information on laboratory and animal studies done using calcium.

Clinical trials
Green Tea To Treat Cancer
There is very little research into whether green tea or green tea extract can help treat cancer.
In 2012 an American study looked at taking a green tea extract called polyphenon E. They gave it to 42 patients. They all had a type of leukaemia called chronic lymphocytic leukaemia . The people in the trial were not taking any other kind of treatment.
The researchers found that in a third of people the number of leukaemic cells lessened. Their lymph nodes also shrank. This was a small trial but the results were promising. We need larger trials before we will know whether green tea or its extracts can help people with cancer.
In another review study in 2018 researchers looked at using green tea and turmeric in people with CLL. They found limited evidence and mixed results that it might work.
Research has shown a possible interaction between green tea and the drug bortezomib . This early research suggested that green tea might stop Velcade from working well. But we need much more research to find out if green tea has the same effect on humans.
Speak to your doctor if you are taking Velcade and you want to drink green tea. You might have to avoid green tea or the extract EGCG. Some people take EGCG as a supplement in liquid or capsules.

The Best Herbal Tea For Prostate Health
The prostate is one of the most important parts of the male body. It is part of the reproductive system and has functions as essential as producing semen, which is responsible for protecting the sperm, it helps the chances of reproduction and its good condition is indispensable for fertilization. The prostate is located below the bladder and in front of the rectum and its size increases very slowly with the passage of time. The average size of the prostate in young men is that of a walnut.
In men, complications in the prostate are very common, in fact, prostate cancer is the leading cause of death worldwide. Men over the age of 50 are at increased risk for conditions in this gland. When the prostate does not work properly it can have serious consequences on men’s health and can sometimes cause pain. Fortunately, nature has medicinal plants for the prostate that help prevent and treat diseases in this area. Learn about the best herbal tea for prostate health in this oneHOWTO article.
Male Tea Drinkers ‘may Be At Greater Risk Of Prostate Cancer’
Men who are heavy tea drinkers may be more likely to develop prostate cancer, according to new research.
A team from Glasgow University tracked the health of more than 6,000 male volunteers over a period of 37 years.
They found men who drank over seven cups of tea per day had a 50% higher risk of developing prostate cancer than moderate and non tea drinkers.
The team said it did not know if tea was a risk factor or if drinkers lived to ages where cancer was more common.
Prostate cancer is the most common cancer amongst men in Scotland and diagnosed cases increased by 7.4% between 2000 and 2010.

Green Tea And Prostate Cancer
Men with prostate cancer who drank green tea had less prostate tissue inflammation, linked to cancer growth, and other changes than those who didn’t drink it, says Susanne M. Henning, PhD, RD, adjunct professor at the David Geffen School of Medicine at the University of California, Los Angeles.
”We were able to show the green tea polyphenols reached the prostate tissue and they did modify inflammation of the prostate,” she says. Polyphenols are antioxidants that protect against cell damage.
Henning’s team assigned 79 men with prostate cancer scheduled to undergo surgery to drink either six cups of brewed green tea or water daily. They did so for three to eight weeks, depending on when their surgery was scheduled.
Before and after the study, Henning obtained urine and blood samples. She collected samples of prostate tissue after the surgery.
She reported on the 67 men who finished the study. Levels of prostate-specific antigen, or PSA, were lower after the study in those who drank green teas. Higher levels of PSA, a protein produced by the prostate gland, may reflect prostate cancer.
An indicator of inflammation, called nuclear factor-kappaB, was also reduced in those who drank green tea compared to those who didn’t, Henning found. Inflammation is linked to cancer growth.
“We were not able to inhibit tumor growth,” she says. But the study length may not have been long enough to show that a longer-term study is needed, she says.
