Cooking Method Affects Vegetables’ Cancer-Fighting Power


Cooking Method Affects Vegetables’ Cancer-Fighting Power
The best way to protect cancer-fighting compounds in cooked vegetables may be to griddle-cook or microwave, according to a new study in the Journal of Food Science. The study found that for most vegetables, cooking on a griddle with no added oil or microwaving maintains the highest levels of antioxidants, which help protect against cancer. Pressure-cooking and boiling lead to the greatest losses, and frying, in addition to increasing fat content, results in intermediate antioxidant loss.
The artichoke was the only vegetable that maintained antioxidant levels with all cooking methods. Beetroot, green beans, and garlic maintained high antioxidant activity after most cooking methods. Celery and carrots actually had increased protective value after all cooking methods.

Mushrooms Protect Against Breast Cancer
Mushrooms may reduce the risk of breast cancer, according to a study conducted in southeast China. Researchers analyzed dietary records from more than 2,000 pre- and postmenopausal women with breast cancer and a group of matched healthy people. Intake of fresh mushrooms (at least 10 grams per day) and dried mushrooms (at least 4 grams per day) decreased the risk by 64 percent and 47 percent, respectively. The most commonly eaten mushroom in this study was the white button mushroom; one small white button mushroom weighs 10 grams. An additional protective effect was seen when mushrooms and green tea were both consumed.

Meat and High-Glycemic Foods Increase Kidney Cancer Risk


Meat and High-Glycemic Foods Increase Kidney Cancer Risk
Red meat and high-glycemic-index foods could be risk factors for kidney cancer, according to a recent study in the Journal of the American Dietetic Association.
Researchers studied the diets of 335 people with renal cell carcinoma, the most common form of kidney cancer, and 337 healthy individuals. They found that men and women who ate red meat five or more times a week were more than four times as likely to develop the disease, compared with those who consumed red meat less than once a week. The study also found that high consumption of white bread, white potatoes, and other high-glycemic-index foods increased cancer risk.

Hot Dogs Strike Out at All-Star Game and in New Jersey



Hot Dogs Strike Out at All-Star Game and in New Jersey
“Warning: Hot Dogs Can Strike You Out—For Good.” That's the message thousands of baseball fans saw on the Cancer Project’s provocative highway billboard as they flocked to the 2009 All-Star Game. Days later, the nonprofit filed a lawsuit in New Jersey asking hot dog manufacturers for a similar warning on product packaging.
The 48-foot-wide digital billboard posted outside Busch Stadium in St. Louis featured an image of hot dogs jammed into a cigarette pack labeled “Unlucky Strike.” The billboard is part of a campaign to persuade Major League Baseball commissioner Bud Selig to put a “dietary disaster” warning label on hot dogs served at Busch Stadium and other Major League Baseball stadiums because processed meats have been convincingly linked to colorectal cancer.
“Baseball stadiums need to be frank about the cancer risk posed by hot dogs and other processed meats,” says Krista Haynes, R.D., a dietitian for the Cancer Project, an affiliate of PCRM. “Just as tobacco causes lung cancer, processed meats are linked to colon cancer. Like cigarettes, hot dogs should come with a warning label that helps baseball fans and other consumers understand the health risk.”

Pumpkin Custard Pie

Made this way, pumpkin pie can actually be healthy! Pumpkin is a rich source of beta-carotene, a well-known cancer-fighting agent, which is also important for cancer survival. Note that the fat in this recipe comes from the commercial pie crust, so a nutrient analysis without the pie crust is also provided.



Directions

Makes 8 servings

1 1/2 cups nondairy milk
4 tablespoons cornstarch
1 1/2 cups solid-pack canned pumpkin or cooked pumpkin
1/2 cup sugar (preferably raw or turbinado) or other sweetener
1/2 teaspoon salt
1 teaspoon cinnamon
1/2 teaspoon ground ginger
1/8 teaspoon ground cloves
1 unbaked commercial pie crust

Preheat oven to 375 F.

In a large bowl, whisk together nondairy milk and cornstarch until smooth, then stir in pumpkin, sugar or other sweetener, salt, cinnamon, ginger, and cloves. Pour into pie crust and bake for 45 minutes, or until firm. Cool before cutting.

Pumpkin pie needs to be covered and kept refrigerated. It will stay fresh for up to three days.

What is inflammatory breast cancer and why is it diagnosed as "the silent Killer"

Inflammatory breast cancer is a rare but very aggressive type of breast cancer in which the cancer cells block the lymph vessels in the skin of the breast. This type of breast cancer is called “inflammatory” because the breast often looks swollen and red, or “inflamed.” IBC accounts for 1 to 5 percent of all breast cancer cases in the United States (1). It tends to be diagnosed in younger women compared to non-IBC breast cancer. It occurs more frequently and at a younger age in African Americans than in Whites. Like other types of breast cancer, IBC can occur in men, but usually at an older age than in women. Some studies have shown an association between family history of breast cancer and IBC, but more studies are needed to draw firm conclusions.
What are the symptoms of IBC? 
Symptoms of IBC may include redness, swelling, and warmth in the breast, often without a distinct lump in the breast. The redness and warmth are caused by cancer cells blocking the lymph vessels in the skin. The skin of the breast may also appear pink, reddish purple, or bruised. The skin may also have ridges or appear pitted, like the skin of an orange (called peau d'orange), which is caused by a buildup of fluid and edema (swelling) in the breast. Other symptoms include heaviness, burning, aching, increase in breast size, tenderness, or a nipple that is inverted (facing inward) (3). These symptoms usually develop quickly—over a period of weeks or months. Swollen lymph nodes may also be present under the arm, above the collarbone, or in both places. However, it is important to note that these symptoms may also be signs of other conditions such as infection, injury, or other types of cancer.

How is IBC diagnosed? 
 Diagnosis of IBC is based primarily on the results of a doctor’s clinical examination (1). Biopsy, mammogram, and breast ultrasound are used to confirm the diagnosis. IBC is classified as either stage IIIB or stage IV breast cancer (2). Stage IIIB breast cancers are locally advanced; stage IV breast cancer is cancer that has spread to other organs. IBC tends to grow rapidly, and the physical appearance of the breast of patients with IBC is different from that of patients with other stage III breast cancers. IBC is an especially aggressive, locally advanced breast cancer.
 Cancer staging describes the extent or severity of an individual’s cancer. (More information on staging is available in the National Cancer Institute (NCI) fact sheet Staging: Questions and Answers at http://www.cancer.gov/cancertopics/factsheet/Detection/staging on the Internet.) Knowing a cancer’s stage helps the doctor develop a treatment plan and estimate prognosis (the likely outcome or course of the disease; the chance of recovery or recurrence).
