8 Things You Can Do To Cut Your Risk Of Cancer

Feb 26, 2009 in Health

According to the World Cancer Research Fund (via New Scientist Magazine), lifestyle changes could cut cancer by 1/3 in developed countries and 1/4 in developing countries.

"People think that somehow cancer comes from heaven, or Darwin, or from their parent's genes, but that's not always the case," says Michael Marmot, chair of the WCRF panel that produced the report. "A third are caused by smoking, and approximately a third are related to diet and physical activity."

Cutting the risk of cancer by a third.  Sign me up.  So what are the WCRFs recommendations?  Nothing you haven't heard before, but they're always worth repeating.

  1. Be as lean as possible without being underweight.  WCRF suggests shooting for the lower end of the normal range for your BMI.
  2. Be physically active for at least 30 minutes per day.  The recommendation is actually 30 minutes of vigorous activity or 60 minutes of moderate activity.  (Note to self - that doesn't include time spent blogging!)
  3. Limit consumption of energy-dense foods (high in fats and/or sugars, and/or low in fiber) and avoid sugary drinks.  In the olden days that would have been guaranteed if you were a vegan, but today there's a proliferation of vegan junk food and vegan processed foods out there, so make smart choices!
  4. Eat more of a variety of vegetables, fruits, whole grains, and pulses (legumes) such as beans.  "Basing our diets on plant foods (like vegetables, fruits, wholegrains, and pulses such as beans), which contain fibre and other nutrients, can reduce our risk of cancer."
  5. Limit consumption of red meat (such as beef, pork and lamb) and avoid processed meats.  Obviously, this is not an issue for those of us eating vegan, but it's important info for our omnivorous family and friends.  The WCRF recommendation is to limit consumption of meats to 500g per week.
  6. Limit alcoholic beverages to 2/day for men and 1/day for women.
  7. Limit consumption of salty foods and foods processed with salt (sodium).  Our daily intake of salt should be less than 6g (2.4g sodium).  To determine how much salt a food contains, multiply the sodium content by 2.5.
  8. Don't use supplements to protect against cancer.  WCRF recommends getting nutrients thru whole foods as opposed to eating a lower quality diet and supplementing.

So while the WCRF doesn't come out and recommend a vegan diet, they do stress basing a diet on fruits, veggies, whole grains, and legumes (pulses).   Easy enough to do when you are eating vegan.

A Vegan Valentine For Him

Feb 10, 2009 in Health

So yesterday we looked at vegan demographics and learned that there are many more females who are vegan than males.  We also learned that most people go vegan for ethical reasons.  Jane likes to point out that this confirms that women tend to be more compassionate than men. Jane also points out that I was vegetarian in my twenties, because of a female... The woman I was dating at the time was vegetarian, and over the course of our relationship, I too became vegetarian.  Now I'm vegan, because of my wife.

So if you're a single female looking for a vegan male, you might have to convert one... and here's some ammunition for you...  A new study says that eating meat significantly increases the likelihood of developing prostate cancer.  Yikes!

Dr. Andrew Roddam of the Cancer Epidemiology Unit at the University of Oxford, and colleagues compiled the results of 12 studies linking prostate cancer to insulin-like growth factor 1 (IGF-1).  These studies included a total of 3,700 men with prostate cancer and 5,200 without it.  Roddam's findings were  published in the Annals of Internal Medicine.

Epidemiological studies have established a link between high circulating serum IGF-1 levels and the risk of later developing advanced prostate cancer. -- Source: National Center for Biotechnology Information (NIH)

Prior research has shown a strong relationship between meat and dairy consumption and levels of IGF-1, and strict vegetarians are known to have far lower levels of the hormone circulating in their blood.

Men in the group with the highest IGF-1 levels were 40 percent (emphasis mine) more likely to be diagnosed with prostate cancer than men with the lowest levels. Among men who did develop cancer, higher IGF-1 levels were also associated with a significantly greater rate of tumor spread. -- Source:  Natural News

Prostate cancer is the most common cancer in men in the UK, accounting for a quarter of all new cases of cancer diagnosed in men. It is the second most common cause of cancer death in UK men after lung cancer. (Source: Science Daily) According to the National Cancer Institute, 15.78% of men born in the United States today will be diagnosed with cancer of the prostate at some time during their lifetime. In other words, 1 in 6 men will be diagnosed with cancer of the prostate during their lifetime.

So ladies, get your guys to go vegan... and you might want to suggest they start taking lycopene which has been shown to help neutralize harmful free radicals that can damage cells.  Lycopene may be valuable in slowing the growth of  cancers in the prostate, lung, and stomach. - Source: American Cancer Society.

Since most of us males are lead around by that certain part of our anatomy, this information could mean that you're twice as likely to convince us!

Blueberries Minus The Milk

Feb 05, 2009 in Health

One of the Eight Foods To Eat Every Day is blueberries.  Blueberries also happen to be one of my favorite foods.  I will often add them to whatever smoothie I am having for breakfast.  Or I'll drop a handful into my cereal or oatmeal.  I love blueberry muffins.  And, in the summer, when they're in season and plentiful, Jane makes a killer blueberry pie!

The reason blueberries are so good for you is that they are packed with polyphenols which provide blueberries with antioxidants.  However, according to a new study reported in the journal Free Radical Biology and Medicine, the antioxidant power of blueberries is significantly reduced by consuming blueberries with milk.  This has to do with the protein in milk. The study was conducted using people who consumed their blueberries with milk or water.

The blood work of  people who consumed the blueberries with milk did not show an increase in levels of plasma antioxidant capacity.  The conclusion the authors of the study draw is that  the best way to gain maximum benefits from blueberries (and other fruits eaten for their polyphenol content) is to consume them either one hour before protein is consumed, or two hours after.

So while we're not consuming dairy, we usually eat our blueberries with almond milk, also a source of protein.... We'll have to stop doing that if we want to get the full antioxidant benefits of our blueberries.

Why Trans Fats Are Bad For Your Health

Nov 10, 2008 in Health

A week or two ago we wrote a post complaining that Tofutti uses partially hydrogenated vegetable oil (trans fats) in their cream cheese alternative.  I was expressing some frustration that Tofutti does make a version of the cream cheese without the trans fats, but the one that is most easily found contains trans fats (something we try to avoid at all costs).  We received a few e-mails questioning why this is so bad.  So here's a brief tutorial...

Partially hydrogenated oils = trans fats.

Trans fats = bad.  Bad enough, in fact, for New York City to ban the use of them in restaurant foods as early as December 2006 (the first city in the US to do so).  Seattle and Boston have jumped on the bandwagon this year as well.  Not to be outdone, California banned the use of trans fats in restaurant food in July, the first state to do so.  It isn't a smooth transition.  Many vendors are complaining.  Trans fats are easier to use, stable longer, and cheaper.  But they are one of the most unhealthy things you can consume.

Why are trans fats bad?  Trans fats are bad for your heart.

Tans fats have also been found in scientific studies to lower high-density lipoproteins, the “good” cholesterol, while increasing low-density lipoproteins, the “bad” cholesterol, high levels of which contribute to the onset of heart disease, the leading cause of death in California and the nation.  Dr. Clyde Yancy, incoming president of the American Heart Association, said a 2 percent increase in trans-fat intake could result over time in a 25 percent increase in the likelihood of developing coronary artery disease.

The AMA came out with a policy today to support any state or federal effort to  ban the use of trans fats in restaurants and bakeries.  (They're also against texting and driving, saying texting increased the amount of time your eyes are off the road by 400%.  Yikes!  DON'T TEXT AND DRIVE PEOPLE!!!)

According to AMA board member Dr. Mary Anne McCaffree, "Trans fats have been proven to raise LDL (low density lipoprotein), the bad cholesterol, while lowering HDL (high density lipoprotein), the good cholesterol, which significantly increases the risk for heart disease."

According to the comprehensive Nurses' Health Study -- the largest investigation of women and chronic disease -- trans fats double the risk of heart disease in women.

As Maija commented, it's likely that trans fats will be banned in the next few years, at least in the western world. So why not get a head start...  When you're in the grocery store check your product labels for Trans Fats.  They should read 0 grams.  If they don't, you should look for a healthier alternative.
