Study: A Salad A Day Could Keep This Cancer Away

We recently lost actress Farrah Fawcett to colorectal cancer. Now a new study says women can protect themselves from the same fate by simply eating more vegetable salads. Here's what you need to know.- By Colette Bouchez

It's clear that any medical headlines hitting the front page these days are linked to the tragic and untimely death of Micheal Jackson.

But if you're a woman, it would be wise to pay attention to the less publicized, but possibly more relevant cause of death of superstar – Farrah Fawcett . Succumbing to rectal cancer, Fawcett is within a growing number of women diagnosed with this disease, as well as colon cancer every year.

And now a new study shows that a simple dietary change may have saved her life.

While once thought of as primarily a “man's problem” ( I lost my own father to colon cancer more than 30 yars ago) according to the American Cancer Society estimates today, the number of women with colon cancer is greater than men. Indeed, according to ACS estimates in 2009 some 54,000 women are expected to be diagnosed with this disease, compared to 52,000 men. An additional 17,000 women are expected to be diagnosed with rectal cancer – the type that killed Farah Fawcett at age 62. Nearly 25,000 women are expected to die of these two diseases in 2009, predicts ACS.

But this week, the news is encouraging. A new study shows we can substantially reduce our risks by as much as 70% - and all it's going to take is adding a few more leafy and green vegetables to our dinner plate. As the most powerful source of the B vitamin folate, a salad a day may just keep colon cancer away!

Indeed, in a new study published this week in the European Journal of Clinical Nutrition, researchers from Seoul, Korea found that women who had the highest intake of foods rich in the B vitamin folate experienced up to a 66 percent reduction in the risk of colon cancer and a 70% reduction in the risk of rectal cancer.

“We found a statistically significant relationship between higher dietary folate intake and reduced risk of CRC, colon cancer and rectal cancer in women,” wrote the researchers, who hail from Korea’s National Cancer Center, Hallym University, Inha University College of Medicine, and Seoul National University.

Study Details & Why A Vitamin Pill Won't Help You

In this hospital-based study doctors analyzed dietary data from nearly 600 men and women between the ages of 30 and 79, all of whom had been diagnosed with colorectal, colon or rectal cancer. Among the factors they sought out were the patients intake of foods high in the B vitamin folate – such as cow peas, chick peas, spinach,lentils, broccoli, peas,and lettuce.

The researchers then compared the dietary data to that of some 500 case controls – men and women in the same age group who did not have this cancer.

The Result: Women who had the highest intake of foods rich in folate had up to a 64% reduced risk of colorectal cancer, a 66% reduce risk of colon cancer, and up to a 70% reduced risk of rectal cancer.

Interestingly, the men in the study did not appear to gain cancer-reducing benefit from eating these same high folate foods.

But if you think you can cheat the system by continuing to eat cake instead of salad and just get your folate from a vitamin pill ….not so fast! A growing body of evidence suggests that folic acid, the synthetic form of folate that is not only basis for vitamin supplements but also the fortification found in founds like flour and other grain products, may not offer you the same protective effects. In fact, for some folks, synthetic folic acid supplements could even be harmful.

Folic Acid Supplements: What You Should Know

Clearly, some studies, like the one published today, offer evidence that folate can reduce the risk of some cancers in women. Other research, however, has shown the opposite – and now some experts think they know why.

The key appears to be the difference between the way the body processes the natural folate found in foods and how it deals with it's synthetic cousin folic acid, which is what you get in both vitamin pills and enriched grain products.

More specifically, as the synthetic folic acid passes through the intestinal wall, a conversion process must take place to turn it into folate – which the body can use. Now there is some evidence that a type of oxidation that occurs during the process can be harmful to some people.

“In select circumstances in which an individual who harbours a pre-cancerous or cancerous tumour consumes too much folic acid, the additional amounts of folate may instead facilitate the promotion of cancer,” says Joel Mason, a researcher from USDA Human Nutrition Research Center on Aging at Tufts University in an article featured in the journal Nutrition Review.

Mason adds that "The fact that folic acid, which is not a naturally occurring form of the vitamin, is used by food and pharmaceutical industries for fortification and supplementation is potentially of importance.”

So, while natural folate found in foods may be beneficial, synthetic folic acid may not be – at least when it comes to colon cancer.

Women, Pregnancy and The Folic Acid Controversy

For women, however, the controversy over synthetic vs natural folate takes on even greater meaning in light of the overwhelming medical literature showing that adequate folate intake during pregnancy remains the single most important way to reduce the risk of neural tube defects, and related forms of mental retardation.

As a result, all pregnant women in the US, Canada and most nations worldwide are now prescribed folic acid supplements both before and during their pregnancy. What's more to help ensure adequate folate intake even more, in 1998 both the US and Canada ruled that all grain products sold in these countries must be fortified with folic acid.

But does folic acid offer the same level of pregnancy protection that was found in the natural folate studies? And could it ever be harmful?

Most obstetricians agree that folic acid supplements used during pregnancy at the prescribed amount ( up to 400 mcg daily) are helpful and not likely to cause any harm.

Indeed, preliminary data has shown that the supplementation has led to as high as a 50% reduction in neural tube defects in the US, Canada and Chile. And while the European jury is still out as to how much it's really helped, results are expected to mirror those found elsewhere.

That said, to help further insure the health of your baby – and begin to insure your own good health against colorectal cancer now and in the future - most experts agree it's a good idea to keep whole, healthy food sources of folate on your shopping list as well – including spinach, brocholi, cow beans, chick peas, lentils, peas and lettuce.

Not coincidentally, these same foods have also been linked to a lower incidence of a number of cancers, as well as a decrease in heart disease

New Studies Confirm New Super Health Foods

Yes, I know, a trip to the supermarket is almost as costly as visiting your local jewelry store. Or, as a friend of mine says, if fresh fruit were diamonds, they would cost less!

But if you, like me, would rather pony up your hard earned dollars to the local grocer than the local pharmaceutical company then pay attention: There is important new healthy food news you'll be happy to hear.


Eat Grapes - Lower Cholesterol & Blood Pressure

In a new study just published in the journal Nutrition, a group of Spanish researchers found that the fiber in red grapes might help reduce the risk factors for heart disease more than any other type of fibrous grain.

In one sixteen week study of 34 folks who received a daily supplement of red grape fiber, doctors noted cholesterol levels were cut by 9 percent, with a similar drop in LDL – the “ bad” cholesterol. Moreover, blood pressure came down by 5 percent.

Results were even more profound in the 13 participants who went into the study with high cholesterol. Results show they experienced a 14 percent reduction in total cholesterol levels and a nearly 12% reduction in “bad” LDL cholesterol.

This same subgroup also saw a whopping 18.6 reduction in total triglycerides – the blood fats which some say are an even more accurate predictor of heart disease.

Across the board researchers say results with grape fiber were higher than what has been previously noted in studies on other types of fiber, including oats or psyllium.

The reason for the grape fiber success? Experts theorize it was the combination of the fiber and grapes high antioxidant content that came together to offer a one-two punch against blood fats and blood pressure.

Not only are these nutrient levels higher in grapes, they are also capable of reaching the colon, where they provide additional antioxidant protection. To learn more about this study, click here.

Green Tea, Snoring & Sleep Apnea

If you're lying awake nights because your bed partner snores like an elephant that ate too many peanuts, try slipping them a "mickey" of green tea before bedtime.

According to animal studies just published in the American Journal of Respiratory and Critical Care, green tea and it’s extracts may prove to be a suitable intervention for sleep – related breathing disorders, some of which result in snoring.

Indeed, obstructive sleep disorders, which cause people to momentarily stop breathing hundreds of times each night (of which snoring can be a symptom) also increase the risk of oxidative stress. This is a process many believe is the underlying cause of some neuro-degenerative problems, including memory loss and learning difficulties. Green tea, with its high antioxidant properties may have the ability to counter some of that oxidative stress, and either halt or reduce the damage occurring while we sleep.

In the study, researchers deprived 106 male rats of oxygen similar to what happens during sleep-related breathing disorders in 12-hour segments for a period of 14 days. Half the rats received drinking water laced with green tea, the other half, plain water.

The end result: The rats who drank the green tea showed a 40 percent reduction in blood markers of oxidative stress – and they performed consistently better on tasks involving memory and concentration.

Reseachers credit the success to the high antioxidant content of green tea, which, they point out is 4 times greater than that found in black tea.

While the study has yet to be duplicated in humans taking a cup of green tea after dinner may make a difference in how rested you feel after a night’s sleep. Click here to read the study!

Fish Oil, Colon Cancer & Hyperactivity in Kids!

Want to slash your risk of colon cancer by up to 40 percent? Eat more fish- and increase your overall intake of omega 3 fatty acids, one of the “good fats’ found in not only fish, but foods such as walnuts, flax seed, eggs and fortified soy products.

According to research just published in the journal Cancer Epidemiology, Biomarkers and Prevention, an impressive 22 year study of some 21,000 men found those who had the highest intake of fish meals per week had up to a 40 percent reduction in colon and rectal cancer. Looking specifically at intake of foods containing omega 3 fatty acids, researchers found a 26 percent reduction in colon and rectal cancer.

This is particularly important news for women, who are among a growing group affected by colon rectal cancer. To learn more, click, here .

In a second study just published in the American Journal of Clinical Nutrition a group of French researchers found that increasing levels of omega 3 fatty acids in children helped increase attention spans and decreased levels of hyperactivity.
