Rice to the Rescue

By Posted on Leave a comment on Rice to the Rescue

Making homemade pizza usually involves making a crust that has to be tossed and kneaded and put in a warm place to rise. It’s a good way to include physical activity in your cooking – but at the end of a long day, you may want a simpler solution.

Today’s Health-e-Recipe uses rice for a crust that holds a variety of healthy veggies and part-skim mozzarella. Rice is the go-to grain for many of the 2 million people in the U.S. who have celiac disease, where eating any food that contains a protein called “gluten” can cause severe intestinal problems. Gluten is found in wheat and other grains.

Here, rice allows you to avoid highly processed frozen or delivered pizzas, and even mixes in Parmesan for a delicious cheesy flavor to complement the cancer-fighting garlic, mushrooms, peppers, onions and tomato sauce, whose phytochemicals all work together in this dish to protect your health.

Another Cancer and Diet Claim: The Alkaline Diet

By Posted on 5 Comments on Another Cancer and Diet Claim: The Alkaline Diet

We continue answering questions about diet and cancer myths from our chat last month.

From Kathy:

Does eating an “alkalizing” diet help prevent cancer? I’ve never read a medical study that says this is the case, but boy, there are a lot of books touting eating foods that “alkalize” the body. Is there merit to this, or is it just the fact that most “alkalizing” foods happen to be vegetables that this way of eating may help prevent cancer?

Answer:

A quick search on Google for “alkaline diet” or “pH diet”* results in hundreds of thousands of hits, so yes, it is very popular.  Food is considered alkaline or acid based on laboratory combustion of the food.**

It’s based on the claim that cancer cells thrive in an acidic environment and can’t survive in alkaline surroundings, so an “alkalizing diet” would promote a more alkaline environment in the body.  There are problems with this claim.

1.  The studies finding that cancer cells thrive in an acidic environment were done in a laboratory setting.  It would be nearly impossible to alter the cell environment to create a less-acidic environment in our bodies.  For example, the stomach is very acidic for proper digestion, so we wouldn’t want it more alkaline.

2.  Our acid-base balance is well regulated – blood pH is tightly controlled normally by the body between 7.35 and 7.45.  If it becomes too acid or alkaline, that could be life threatening and it is typically an indication of a serious health problem, not the underlying cause.

Generally, vegetables, fruits and seeds are considered to be alkaline and meats, beans, nuts and grains are acid. So, as you say, the diet would be rich in vegetables and fruit and lower in meat.  This is similar to AICR’s diet recommendations for lowering cancer risk – a mostly plant-based diet, limiting red meat to no more than 18 oz. per week, and avoiding processed meat.

However, some very healthy foods are listed as “acidic” such as whole grains, beans and even some vegetables such as carrots.  So keep it simple and follow AICR’s New American Plate to lower cancer risk simply by filling at least 2/3 of your plate with vegetables, fruits and whole grains, and 1/3 or less with meat, poultry and fish.

There are many claims about this diet including weight loss, more energy and solutions to other common problems, but according to the American Dietetic Association, “large, well-designed clinical trials on the effectiveness of the many claims made for the alkaline diet are lacking.”

Just a note:  the pH of urine can be changed somewhat by diet because the kidney is key in maintaining the proper body pH.  Some proponents of this diet encourage checking your urine pH to see if your diet is alkaline or acid.  Keep in mind that an increase in acid or alkaline in the urine reflects the fact that the kidney is doing its job.  A change in urine status does not indicate a change in “overall body pH.”

Other factoids:

*pH is a measure of acidity/alkalinity on a scale of 1-14. Seven is neutral, with anything above that alkaline and anything below that acid.

**Alkaline-ash foods or Acid-ash foods:  this is based on the ash that remains after the combustion of foods under laboratory conditions.

More Cancer Survivors: More Healthy Living

By Posted on Leave a comment on More Cancer Survivors: More Healthy Living

A new batch of cancer statistics was published online today and it bodes good news, relatively speaking, for people diagnosed with cancer.  The report found that overall cancer mortality rates have steadily decreased over the last 16 years, translating to approximating 767,000 fewer deaths from cancer.

Avoiding inactivity is one of the latest pieces of advice for cancer survivors.

To read the report visit CA: A Cancer Journal for Clinicians.

The lower cancer death rate occurred in all racial/ethnic groups in both men and women, with the exception of American Indian/Alaska Native women, in whom rates were stable.

A few highlights from the report:
•    Among men, death rates for all races combined decreased by 21.0 percent between 1990 and 2006, with decreases in lung, prostate, and colorectal cancer rates accounting for nearly 80 percent of the total.

•    Among women, overall cancer death rates between 1991 and 2006 decreased by 12.3 percent, with decreases in breast and colorectal cancer rates accounting for 60 percent of the total.

•    Breast, lung, and colon are the three most common types of cancer in women, accounting for an estimated 52 percent of cases in 2010. Breast cancer alone is expected to account for 28 percent of all new cancer cases among women.

And although the lower rates of mortality (and incidence) is overall great news, cancer still accounts for more deaths than heart disease in persons younger than 85 years, the authors note.

The report comes at a time when research is now clearly showing that a healthy lifestyle can help cancer survivors, both physiologically and psychologically. For the latest news and information, visit AICR’s News section for Cancer Patients and Survivors News section.
