THE 10 TOP THINGS
YOU CAN DO TO PROTECT YOURSELF AGAINST
CANCER
[We offer the
following article for your information and encouragement. As
followers of Christ, we should want to do all we can to
maintain a healthy lifestyle that will help protect ourselves
from cancer and other debilitating diseases. RH]
It’s easy to
get blown about in the gust of the latest “NEWS FLASH” study.
One night on TV news, for instance, you might hear that
seafood’s good for you. The next night, another report
might roar that seafood poisons you.
Oy vey! Too
often, we feel a great Cloud of Confusion engulfing even
the simplest of nutrition questions.
That’s why
a large new review on lifestyle habits and cancer prevention
is so important. It is not based on one small media-sensationalized
study. Rather, this review has distilled the findings of more
than 7,000 studies into one 517-page statement, and
it is supported by the top health organizations worldwide,
including the Food and Agriculture Organization of the
United Nations and the World Health Organization Titled “Food,
Nutrition, Physical Activity and the Prevention of Cancer:
a Global Perspective” and coordinated by the World Cancer
Research Fund and the American Institute of Cancer Research,
the review is the result of a five-year examination by
a panel of 21 distinguished scientists from all over the
world.
They didn’t
start from scratch, either. This is the second edition
(the first edition was published in 1997) of a volume that
Dr. Gail Harrison, UCLA researcher and member of the Institute
of Medicine, calls “the Bible of Nutrition and Cancer.”
This is
science. To paraphrase the old E.F. Hutton commercial:
When this WCRF/AICR document talks, people ought to listen.
It is the largest report ever on lifestyle and cancer prevention.
There’s more
good news. The report outlines 10 key lifestyle recommendations
that offer powerful means of reducing risk for many, perhaps
most cancers. And those 10 recommendations closely resemble
what you’re already following – the Pritikin Program.
So for optimal
cancer prevention, there’s no need to get caught up in
the latest chaos on the nightly news. There’s no need to
wonder if you’re doing the right thing. You are.
Below are the
report’s 10 guidelines for cancer prevention:
Recommendation
1: Maintain body weight within the normal range throughout
adulthood.
“Maintenance
of a healthy weight throughout life may be one of the most
important ways to protect against cancer,” stated the independent
panel of 21 leading scientists from institutions worldwide,
including the University of Pennsylvania, University College
London, Kyushu University in Japan, and Harvard School
of Public Health.
A key message
throughout the 517-page report is that there’s much we
can do to control cancer risk. That’s important to stress.
Many people recognize they have the power to reduce heart
disease risk, but they think of cancer as this big bad
ogre that pounces out of nowhere.
That just isn’t
so. “Evidence shows that only a small proportion of cancers
are inherited. Environmental factors are most important
and can be modified,” concluded the international panel
of experts. “Food, nutrition, physical activity, and body
composition play a central role in the prevention of cancer.”
Being as lean
as possible within the normal range from age 21 is optimal
for cancer protection, but at any time in life, it helps
to lose weight if you’re overweight, stated the panel.
Even a 5 to 10% weight loss can be important.
Recommendation
2: Be physically active for at least 30 minutes every
day.
“All forms
of physical activity protect against some cancers as well
as against weight gain,” wrote the WCRF/AICR cancer report.
Optimally,
the report advised, aim for moderate activity, like brisk
walking, which essentially means walking as though you
have somewhere to go (and you’re running a little late).
As fitness
improves, aim for 60 minutes or more of moderate activity – or
for 30 minutes or more of vigorous physical activity – every
day.
Recommendation
3: Limit consumption of calorie-dense foods. Avoid sugary
drinks.
As you learned
at Pritikin, the best way to prevent weight gain is to
steer clear of calorie-dense foods like fat-rich fast foods
as well as dry, processed foods such as chips and candy
bars and even healthier options like bagels, pretzels,
and dried cereals. That’s because all dry, processed foods
pack a lot of calories into very small packages. It’s shockingly
easy to swallow 1,000 to 2,000 calories long before you’ve
satisfied your hunger.
“Food supplies
that are mainly made up of processed foods, which often
contain substantial amounts of fat or sugar, tend to be
more calorie-dense than food supplies that include substantial
amounts of fresh foods,” concluded the new cancer report.
For a low-calorie-dense
diet, fill each day with water-rich, fiber-rich foods like
fruits, vegetables, beans, hot cereals, and potatoes and
other starchy vegetables. Foods with a lot of water and
fiber usually provide a lot of stomach-satisfying volume,
but not a lot of calories.
Avoid calorie-rich,
sugar-rich drinks, too. One in every five calories in our
American diet now comes from beverages (all those grand
lattes are adding up), and that’s a big problem because,
as the cancer report states, “Sugary drinks provide calories
but do not seem to induce satiety or compensatory reduction
in subsequent calorie intake.”
Translated:
Whether you drink a diet coke or a regular coke, you’ll
likely eat the same burger and fries. And you’ll get hungry
about the same number of hours later. Regular coke, in
short, is simply adding more calories to your day, which
can all too easily add more pounds on you.
Recommendation
4: Eat mostly foods of plant origin.
Advised the
international panel of cancer experts: Eat at least five
servings of fruits and vegetables every day, and eat relatively
unprocessed whole grains and/or legumes (beans) with every
meal. “These, and not foods of animal origin, are the recommended
center for everyday meals.”
All these foods
contain “substantial amounts of dietary fiber and a variety
of micronutrients, and are low or relatively low in calorie
density.”
One easy way
to get a lot of veggies into your day, as your Pritikin
registered dietitians taught, is to start each lunch and
dinner with a big satisfying salad. We stress “big.” This
is one case where “super sizing” is a very good thing.
At salad bars,
start with a big bowl and pile on the greens. Then add
lots of colorful veggies and some lean protein, if you’d
like, like beans, tofu, white meat chicken, or seafood.
Beans are really high in fiber, so they will satisfy your
appetite for a long time.
Recommendation
5: Limit intake of red meat and avoid processed meat.
According to
the WCRF/AICR report, red meat, including beef, pork, and
lamb, as well as processed meats like sausage, bacon, hot
dogs, salami, and ham “are convincing or probable causes
of some cancers,” including cancers of the colon, esophagus,
lung, stomach, and prostate.
Moreover, “diets
with high levels of animal fats are often relatively high
in calories, increasing the risk of weight gain.”
The cancer
experts recommend that the population average consumption
of red meat be no more than 11 ounces a week, very little
if any of which is processed.
Instead of
red meat, the experts advised, select white meat poultry
and seafood. “Flesh from wild animals, birds, and fish,
whose nutritional profiles are different from those of
domesticated and industrially reared creatures, is also
preferred.”
For optimal
protection against cardiovascular disease, the Pritikin
Program recommends no more than 3.5 ounces (cooked) of
animal protein each day. Your optimal choice is seafood,
except for some of the higher-in-cholesterol selections
like eel, conch, and squid. Once a week, you may opt for
skinless white poultry or grass-fed, free-range wild game
such as buffalo, elk, and moose. Try to limit other red
meat choices to once a month – or not at all.
Recommendation
6: Limit alcoholic drinks.
Though the
WCRF/ACIR panel took into account the evidence that modest
amounts of alcoholic drinks are likely to protect against
coronary heart disease, the data on cancer indicate that “even
small amounts of alcoholic drinks should be avoided.”
Alcoholic drinks
are linked to mouth, larynx, and colorectal cancer and
may also cause liver cancer.
If you consume
alcoholic drinks, the cancer report advises you limit consumption
to no more than two drinks a day for men and one drink
a day for women.
These modest
levels of consumption are associated with reductions in
heart disease risk only among middle-aged and older
individuals, because heart disease is a much larger factor
in these groups.
From a cardiologist’s
point of view, the drinking age should be about 40, since
anyone younger does not benefit from alcohol. They simply
drive cars into ditches, or worse. About 100,000 Americans
die from alcohol-associated diseases and trauma like car
accidents each year, due mostly to overconsumption of alcohol.
Recommendation
7: Limit consumption of salt.
“Salt is necessary
for human health and life itself, but at levels very much
lower than those typically consumed in most parts of the
world,” stated the cancer report. Salt and salt-preserved
foods are a probable cause of some cancers, particularly
stomach cancer.
To avoid cancer,
the panel recommends that consumption of processed foods
with added salt be less than 2,400 milligrams of sodium
a day. (Salt is about 40% sodium and 60% chloride.)
To avoid not
only cancer but also cardiovascular-related diseases like
hypertension and heart attacks, the Pritikin Program, in
line with the Institute of Medicine, advises that adult
Americans limit their consumption of sodium to 1,200 to
1,500 milligrams a day, depending on age. People aged 19
to 50 should consume 1,500 mg or less of sodium a day.
Those 51 to 70 should cut sodium to1,300 mg or less, and
those over 70 should aim for 1,200 mg or less.
That’s no small
task when you live in a country like the U.S. where one
restaurant plate of pasta marinara can tally up a whopping
3,000 mg of sodium, and, calorie for calorie, corn flakes
and most breads pack in about twice as much sodium as potato
chips.
And do we ever
pay the price. High blood pressure in America is at an
all-time high. Our lifetime chance of getting high blood
pressure is now over 90%. It’s a huge problem because hypertension
(persistent high blood pressure) increases the risk of
dying from cardiovascular disease three-fold.
The good news:
blood pressure can fall dramatically, studies on the Pritikin
Program have found. In a meta-analysis of 1,117 hypertensives
at the Pritikin Longevity Center, 55% of those on hypertension
drugs lowered blood pressure to normal, medication-free
levels. After just three weeks, they returned home free
of their anti-hypertensive drugs.
Recommendation
8: Aim to meet nutritional needs through food alone,
not supplements.
Consuming supplements
for cancer prevention “might have unexpected adverse effects,” concluded
the WCRF/AICR panel. “The best source of nourishment is
foods, not dietary supplements.”
Suspect, too,
are “fortified” foods, a trend that began in the U.S. in
1988 – when nearly every processed food was “Fortified
With Oat Bran” – and has recently given us the likes of
Cocoa Puffs With Whole Grain Goodness. Another common marketing
trick: Turning lousy food into a “health” food just because
one ingredient has been removed (Trans-Fat-Free Crisco).
Ironically,
the only foods that have never been labeled as “fortified” or “good
for you” are the most genuinely healthful foods of all,
the ones sitting quietly in the produce section, the lowly
carrots and green beans and other fruits and vegetables.
They’re naturally rich in virtually every nutrient we need,
but never at artificially high, potentially dangerously
levels.
Ultimately,
argues Michael Pollan in his compelling book on the food
industry, The Omnivore’s Dilemma, we’re better off avoiding foods
bearing health claims. “They’re apt to be heavily processed,” Pollan
writes, “and the claims are often dubious at best.
“Don’t forget
that margarine, one of the first industrial foods to claim
that it was more healthful than the traditional food it
replaced, turned out to give people heart attacks.” When
Mars can boast about its plant-sterol-enriched chocolate
bars and Kentucky Fried Chicken about its trans-fat-free
drumsticks, health claims have become hopelessly compromised.
Our best bet:
Eat real food. Whole fresh food. Yes, in our present state
of confusion, that’s easier said than done. Here’s a tip:
Buy foods your great-great grandmother would have recognized
as food. Foods like fruits, vegetables, beans, potatoes,
yams, oats, corn on the cob, and brown rice. These foods,
mostly of plant origin, are, as the panel of leading cancer
experts concluded, your best source of nourishment.
Special Recommendation
1: Mothers to breastfeed; children to be breastfed.
The evidence
on cancer and other diseases shows that sustained exclusive
breastfeeding is protective for the mother as well as the
child. (Exclusive means human milk only, with no other
food or drink, including water.)
The panel therefore
recommends that mothers breastfeed infants exclusively
up to six months and continue with complementary feeding
thereafter.
Special Recommendation
2: For cancer survivors, follow the recommendations for
cancer prevention.
If able to
do so, and unless otherwise advised, the WCRF/AICR report
recommends that cancer survivors (all cancer survivors,
before, during, and after active treatment) lifestyle guidelines
outlined in its report.
There is evidence
that people who’ve had colon cancer are significantly less
likely to suffer a recurrence if they adopt a healthier
diet and lifestyle. This also appears to be the case for
cancers of the breast and prostate.
Finally, throughout
its report, the expert panel emphasizes the importance
of not smoking and avoiding exposure to tobacco smoke.
Summing up
Lose weight.
Eat your vegetables. Limit salt. Cut out fatty animal products
and refined carbs. Don’t smoke. Exercise daily. That’s
how you prevent cancer. It’s not new news. It won’t make
sexy headlines that sell newspapers and magazines. But
it works.
More clearly
than ever, the WCRF/ACIR review of 7,000 studies affirms
we have the potential through our food and lifestyle choices
to make a major impact on the cancer risk we each face
in our lives.

[We
believe that Recommendation 8, above, may not entirely
be accurate. It
may be the part of wisdom to add certain basic supplements
to our diet to ensure adequate intake of all nutrients. Megadoses,
of course, are problematic and should probably be avoided. RH]
