Tomatoes Can Ward Off Prostate Cancer

Scientists at the University of Naples suggest that a daily serving of tomatoes could protect against prostate cancer and slow the growth of a tumour in an existing sufferer, reports the Daily Mail.

The study involving mice bred to be genetically susceptible to cancer showed those fed a daily diet rich in tomato extracts were less likely to fall ill – and survived longer if they did.

The findings are the latest in a long line of studies looking at whether tomatoes can combat the disease.

There have been conflicting results with some suggesting benefits and some none at all. [Read more...]

Vegetable Prices Beat Stocks In Arab Bourses

The unusual gap between vegetable and financial markets recently began to emerge.

Since we are halfway through Ramadan, let us take a look at some paradoxes that are both sad and amusing. The Arab financial markets, ‘bourses’, are the only markets where the prices of stocks are being beaten by the prices in local vegetable markets. With the onset of Ramadan, vegetable prices have reached record rates while stock prices have continued to decrease, therefore increasing the price gap between vegetables and stocks.

As a result, the price of a bundle of parsley has increased from Dh1 to Dh5 during Ramadan, and this is equal to the price of three shares of the Gulf’s best banks that have an annual dividend rate of 20 to 25 per cent from their nominal value. [Read more...]

Breeding Better Broccoli

breeding better broccoli_Carotenoids—fat-soluble plant compounds found in some vegetables—are essential to the human diet and reportedly offer important health benefits to consumers. Plant carotenoids are the most important source of vitamin A in the human diet; the carotenoids lutein and zeaxanthin, found in corn and leafy greens vegetable such as kale, broccoli, and spinach, are widely considered to be valuable antioxidants capable of protecting humans from chronic diseases including age-related macular degeneration, cancer, and cardiovascular disease.

Vegetables in the cabbage family (such as kale, cauliflower, and broccoli) have long been known as especially good sources of dietary carotenoids. Recently, broccoli has emerged as the stand-out member of the species, providing more carotenoids to American consumers than any of its cabbage-family relatives. Yet, little has been understood about the carotenoid make-up of this popular green vegetable—until now.

Mark W. Farnham of the U.S. Department of Agriculture, Agricultural Research Service, Charleston, South Carolina, and Dean A. Kopsell from the Plant Sciences Department, University of Tennessee, Knoxville, designed a research study aimed at finding out more about the carotenoid content of field-grown broccoli and determining the effects of genetics and the environment on carotenoid levels.

The duo’s research confirmed that broccoli heads contain abundant levels of lutein, an antioxidant commonly thought to provide nutritional support to eyes and skin. Other carotenoids like beta-carotene, violaxanthin, neoxanthin, and antheraxanthin were also found in broccoli heads, but lutein was clearly the most significant, accounting for about half of all carotenoids measured.

The researchers also discovered that when it comes to breeding broccoli, lutein levels were linked to the plants’ genetics; the environment in which the vegetables were grown had little effect on carotenoid production.The full study, published in a recent issue of HortScience, includes recommendations for vegetable breeders interested in producing vegetables that feature higher lutein levels. “Ultimately,” reported Farnham and Kopsell, “this research indicates that breeding cultivars with increased levels of this particular carotenoid may be feasible.” redOrbit

For Some Of Us, Health Reform Begins At Home

for some of us, health reform begins at home_During a recent visit to my cardiologist, I was asked, “Do you eat red meat?” An occasional burger, I lied. But a high cholesterol count had already tipped my hand. The doctor prescribed medication and recommended that I switch from burgers to broiled chicken and fish.

I protested. Cholesterol medication can cause impotence, among other ailments, according to those TV ads. To which the doctor replied that high cholesterol causes strokes and heart attacks and that, just in case I hadn’t noticed, dead men don’t have sex.

So it’s off to the pharmacy instead of the rib shack.

When President Obama talks about health care reform, I hope he succeeds in making the case for those 46 million Americans who are uninsured. But I’d also like for him to talk about the importance of making healthy life choices. I could sure use the encouragement.

“You drink sodas?” the cardiologist asked.

“Maybe with a hot dog,” I said.

“You’re a grown man, and you’re still doing that?” she asked.

But everybody else does it, right? According to the National Hot Dog and Sausage Council, Americans ate more than a billion wieners during the summer. “I exercise,” I told the doctor.

She was not impressed. “Haven’t you read about people who play tennis and run marathons and drop dead because their arteries were clogged?” She went on to say the food industry did not care about my health and warned, “Any processed food that you see advertised, stay away from it.”

The recommended food plan was not inspiring: oatmeal without sweeteners but with soy milk and cinnamon; four to six glasses of water a day to flush out some of the fat; scrambled tofu. (“It’s better than it sounds. Just try it,” she said.) Also allowed: egg white omelets with hummus and a choice of veggie soy patties or sardines.

I’m supposed to avoid salt and carbohydrates. No white rice, pasta or potatoes. And no daily bread, just daily vegetables, steamed, sauteed, grilled and raw. Help me, Lord.

In a recent opinion piece in The Washington Post, Arthur M. Feldman, a cardiologist and chair of the department of medicine at Jefferson Medical College, wrote: “Unless Congress outlaws McDonald’s, cigarettes, alcohol and idleness and cleans up the environment, no amount of ‘prevention’ will put a dent in the cost of keeping Americans healthy.”

My cardiologist gave me a copy of a recent Consumer Reports on Health, which said that a third of American adults have hypertension and that fewer than half of those with hypertension have it under control. If they ate right and exercised, however, there would be 6.2 million fewer heart attacks and 7 million fewer strokes a year.

A third of American adults are obese, and another third are overweight. Losing just a few pounds would prevent a total of 8.2 million heart attacks and strokes a year. Lowering cholesterol would prevent 12.6 million strokes and heart attacks a year.

I had a lot on my mind when I left the doctor’s office. One thing I didn’t have to worry about was getting an appointment. I had health insurance. Everybody should be so fortunate. Even people who make healthy choices can get sick. High cholesterol and hypertension, for example, are just two of many maladies that can be inherited. You need to see a doctor just to know where you stand. That said, my doctor made clear that no amount of health insurance is going to make healthy life choices for me. No insurance agent will magically appear to stop me from eating a cheeseburger.

The question is: Will I stop on my own, or will the burger have to be pried from my cold, dead hands?

“The problem is getting people to do what we already know they should,” said Javed Butler, deputy chief science adviser for the American Heart Association. “Eat right, exercise, stop smoking; control blood pressure, cholesterol and blood sugar levels; and consider preventive aspirin.

There’s just no way around it. Let’s get going on health care reform. But for people like me, self-care reform could also use a jump-start. By Courtland Milloy, The Press Democrat.
