(NaturalNews) Men who drink coffee regularly may reduce their risk of the most dangerous form of prostate cancer, according to a study conducted by researchers from Harvard Medical School and presented at a Houston conference of the American Association for Cancer Research.

Prostate cancer kills more than 27,000 men in the United States each year, making it the second deadliest cancer in men, surpassed only by lung cancer. Roughly 200,000 new cases are diagnosed in the country each year.

"Few studies have looked prospectively at this association, and none have looked at coffee and specific prostate cancer outcomes," said lead researcher Kathryn Wilson. "We specifically looked at different types of prostate cancer, such as advanced vs. localized cancer or high-grade vs. low-grade cancers."

Researchers studied 50,000 men between 1986 and 2006, recording their coffee consumption once every four years. They found that the rate of advanced prostate cancer was 60 percent lower in those who drank six or more cups of coffee per day than in those who never consumed the beverage. Those who drank between four and five cups per day lowered their risk by 25 percent, while those who drank one to three cups lowered it by 20 percent.

The same risk reduction was seen regardless of whether the men drank caffeinated or non-caffeinated coffee.

No relationship was seen between coffee consumption and the risk of developing prostate cancer, only the risk of developing cancer that eventually progressed into an advanced stage. This might explain why prior studies have found no connection between coffee drinking and prostate cancer risk.

The researchers are unsure exactly how coffee affects cancer risk, although it may have something to do with levels of the sugar-regulating hormone insulin. High insulin levels have previously been correlated with prostate cancer risk, and coffee has been shown to increase the body's use of the hormone.

Coffee is one of the most popular beverages in the world. It is consumed by 54 percent of U.S. adults.

(NaturalNews) Kidney stones are solid pieces of material that form in a kidney. They can stay there or they may travel down the urinary tract until they are eliminated naturally. Unfortunately, kidney stones can also get stuck in the ureter, bladder or urethra. The result can be bleeding, blockage of urine flow and excruciating pain. Thankfully, there are natural ways to greatly reduce your risk of having this most common disorder of the urinary tract, including simply drinking lemonade.

If you've ever experienced the agony of having kidney stones stuck in your urinary tract, you know this is no minor problem. In fact, kidney stones can lead to serious infections and major surgery.

"Back and abdominal pain, blood in the urine, and nausea or vomiting, are the three classic symptoms of kidney stones," Roger L. Sur, MD, director of the University of California at San Diego Comprehensive Kidney Stone Center said in a press statement. "You don't have to have all three, but any of them will come on quickly and be hard to ignore. When you have extreme pain, you should see your doctor or go to an emergency room right away, especially if a fever is present. The presence of fever indicates that you may have an infection in your blood stream which can be life threatening."

Dr. Sur explained that kidney stones composed mostly of calcium can be caused by too much salt in the diet. Excess salt stimulates calcium excretion in urine and that can lead to stone formation. Another type of fairly common kidney stones is formed from uric acid, a waste product that may be caused by a high-protein diet.

Treatment for kidney stones can involve drugs, surgery, or a shock wave procedure called lithotripsy that breaks up the stones. But even after medical treatment, they can come back. "There is a 50 percent chance of getting another stone within five to ten years if you've already had one," Dr. Sur explained.

Of course the best strategy for kidney stones is to avoid getting them in the first place. Reducing dietary salt, excess calcium and protein and drinking plenty of fluids can slash the risk of kidney stones – and now it turns out lemonade can help, too. In a recent study headed by Dr. Sur, lemonade therapy consisting of drinking four ounces of reconstituted lemon juice in two liters of water per day was found to significantly decrease the rate of kidney stone formation from 1.00 to 0.13 stones per patient.

So what is it about lemonade that zaps kidney stones? Dr. Sur pointed out in a media statement that lemons have the highest concentration of citrate of any citrus fruit -- and citrate naturally inhibits kidney stone formation. Other fruit juices not only have less citrate but they are also sometimes supplemented with calcium and oxalate, the very compounds that make up the majority of kidney stones.

Natural health tip: skip homemade or store bought lemonade if it's loaded with sugar. Instead, sweeten lemonade to taste with healthier choices -- honey or stevia.

(NaturalNews) The millions of Americans with heart disease and type 2 diabetes didn't develop these diseases out of the blue. Their disorders are the result of a cascade of problems including high blood pressure, insulin resistance, abdominal fat and other symptoms of metabolic syndrome. Now University of Michigan (U-M) scientists say they've found something that could help put the brakes on this downward spiral of ill health. It's not a new drug but a delicious and easy lifestyle change: just eat grapes.

The U-M research findings, announced April 26th at the Experimental Biology convention held in Anaheim, California, showed grape consumption lowered blood pressure, improved heart function and reduced other risk factors for heart disease and metabolic syndrome, a condition affecting an estimated 50 million Americans that often leads to type 2 diabetes. The scientists stated the beneficial effects of grapes appear to be due to the rich supply of phytochemicals in the fruit.

The research team tested a mixture of green, red and black grapes on laboratory rats that are prone to being overweight. For three months, one group of the animals ate powdered grapes mixed into their regular feed, which was devised to imitate a typical high-fat, American style diet. A control group of similar rats received no grape powder in their food (which was supplemented so it had the same number of calories as the grape-added diet).

The results of the experiment showed the rats eating the grape-enriched diet had lower blood pressure, better heart function, and reduced indicators of inflammation in the heart and the blood than rats who received no grape powder. What's more, the grape eating rats had lower triglycerides and improved glucose tolerance even though there was no change in their body weight.

"The possible reasoning behind the lessening of metabolic syndrome is that the phytochemicals were active in protecting the heart cells from the damaging effects of metabolic syndrome," Steven Bolling, M.D., heart surgeon at the U-M Cardiovascular Center and head of the U-M Cardioprotection Research Laboratory, said in a statement to the media.

While this was an animal study, the scientists noted there's good reason to think eating grapes -- along with tried-and-true natural strategies such as eating little saturated fat, keeping weight under control and exercising regularly -- could have broad effects on the development of heart disease and metabolic syndrome in people.

"Reducing these risk factors may delay the onset of diabetes or heart disease, or lessen the severity of the diseases," said E. Mitchell Seymour, Ph.D., lead researcher and manager of the U-M Cardioprotection Research Laboratory. "Ultimately it may lessen the health burden of these increasingly common conditions."

As NaturalNews has previously reported, researchers have found that components of grapes contain a myriad of health benefits. For example, grape seed extract has been found to kill leukemia cells (http://www.naturalnews.com/025248_c...) and drinking grape juice appears to improve memory in older adults (http://www.naturalnews.com/023591_g...).

Editor's note: NaturalNews is opposed to the use of animals in medical experiments that expose them to harm. We present these findings in protest of the way in which they were acquired.

(NaturalNews) The rate of cardiovascular disease is much lower in Japan than in the U.S. and now scientists at the Cardiovascular Research Center and Department of Physiology at Temple University School of Medicine in Philadelphia think they know why. People in Japan eat rice virtually every day and rice -- especially the brown and only partially "polished" varieties -- contains a natural compound that appears to guard against high blood pressure and heart disease.

Brown rice is already well known as a healthy food choice because it's a good source of fiber, B vitamins and other nutrients. But new research just presented by Temple University researcher Satoru Eguchi at the American Physiological Society's Experimental Biology conference held in Anaheim, California, reveals another powerful health benefit. A specific natural compound found in a layer of tissue surrounding grains of brown rice inhibits an endocrine protein known as angiotensin II. In excess, angiotensin II can trigger serious cardiovascular problems.

This is enormously significant news because angiotensin II is a well documented culprit in the development of hypertension and atherosclerosis. Angiotensin II constricts arteries, increases blood pressure and forces the heart to work harder. It also thickens and stiffens the walls of the heart and blood vessels.

Big Pharma has created a huge industry producing angiotensin II receptor blockers (ARBs) -- prescription drugs that lower blood pressure by putting the brakes on angiotensin II. Sold under brand names such as Atacand, Teveten, Avapro and Cozaar, the medications are designed to block angiotensin II, thereby relaxing blood vessels so blood pressure is lowered.

But the side effects of these drugs can be serious and even deadly. They include fetal harm (possibly death) if the drugs are taken during pregnancy, dizziness, blurred vision, fainting, decreased sexual ability, infection, chest pain, swelling, trouble breathing and more.The new discovery about rice indicates brown rice or even half-milled rice could be a natural, side-effect free angiotensin II blocker.

Dr. Eguchi, an associate professor of physiology, and his colleagues investigated the subaleurone layer of Japanese rice. Located between the white center of the grain and the brown fibrous outer layer, this sub-layer of rice is loaded with oligosaccharides (complex carbohydrates known to benefit the digestive system) and dietary fibers. But when brown rice is polished to turn it into white rice, this subaleurone layer is ripped off, taking away some of the nutrients. However, the subaleurone layer is preserved not only in brown rice but also in two types of rice popular in Japan -- half-milled (Haigamai) rice or incompletely-milled (Kinmemai) rice.

The Temple research team, working with conjunction with scientists at the Wakayama Medical University Department of Pathology and the Nagaoka National College of Technology Department of Materials Engineering in Japan, removed subaleurone tissue from Kinmemai rice and ran a variety of lab tests that demonstrated the components of this rice layer inhibited angiotensin II activity in cultured vascular smooth muscle cells. Bottom line: the subaleurone rice layer could offer powerful protection against high blood pressure and atherosclerosis by blocking the endocrine protein that can trigger those conditions.

"Our research suggests that there is a potential ingredient in rice that may be a good starting point for looking into preventive medicine for cardiovascular diseases," Dr. Eguchi said in a media statement. "We hope to present an additional health benefit of consuming half-milled or brown rice (as opposed to white rice) as part of a regular diet."

(NaturalNews) Over 23 million American have been diagnosed with type 2 diabetes and another six million are suspected to have the condition but are not yet diagnosed. Diet and proper nutrition play an important role in the prevention and treatment of diabetes. Eating healthy foods in the proper balanced amounts can help lower blood sugar and manage the symptoms of type 2 diabetes. Balancing carbohydrates, eliminating sugars, and adding protein will help stabilize blood glucose in people with type 2 diabetes.

Carbohydrates and Sugar in a Diabetic Diet
Diabetics need to be watchful for "good" carbs and "bad" carbs. Good carbs contain complex carbohydrates and burn slower, helping to stabilize blood glucose. Bad carbs cause insulin to spike in the blood and should be avoided. Bad carbs are found in sugar, refined white flour, corn sugar, and, unfortunately, fruits and juices. Because of the valuable nutrients in fruits, they can be included in a diabetic diet in small amounts, but fruit juices are best avoided. To add fruit juice to the diet without spiking insulin levels, juice can be diluted at least 50/50, so that the benefits of the fruit can be enjoyed without adding sugar to the bloodstream.

Beans for Diabetes
The American Diabetes Association recommends a half-cup of beans a day. Beans contain carbohydrates along with as much protein as an ounce of meat. Beans also contain magnesium and fiber.

Fiber for Type 2 Diabetics
Fiber is necessary in a diabetes diet because it lowers blood sugar. Fiber has been shown to prevent the onset of diabetes and it can also lower LDL cholesterol levels. Grains and beans are an excellent source of fiber, as are nuts, most fruits and vegetables. Potatoes and apples contain an especially soft type of fiber that is easy on the digestive tract. The recommended amount of fiber in the diet is 25 to 30 grams per day.

Nuts: Diabetic Superfood
Nuts are an excellent source of fiber and magnesium, a nutrient needed in a diabetic diet. Omega-3 fatty acids are found in some nuts, including walnuts. Nuts contain healthy fats that are good for the body and help slow the digestion of carbohydrates, leading to a lowering of blood sugar. The American Diabetes Association lists nuts as one of the superfoods for diabetics.

Protein is Good for Diabetics
Add protein to every meal to help slow the release of blood sugar. One quarter of each meal should come from protein foods, advises the American Diabetes Association.

With proper diet, the symptoms of type 2 diabetes can be mitigated or avoided.
