Here's another reason to keep blood sugar in check and maintain a
healthy weight. A new study suggests that having high blood sugar
levels may increase the risk of cancer, independently of body weight.
Scientists at Umea University in Sweden looked at the levels of sugar
in the blood of more than 500,000 people, and then found out if they
later went on to develop cancer.
The results found that people
with high blood sugar levels may be at increased risk of both
developing cancer and also of dying from the disease, and the
association was stronger for women than for men. The strongest blood
sugar-cancer links observed were for pancreatic cancer, particularly in
women, and liver cancer in men.
The American Institute for Cancer
Research, which reported on the study, already recommends limiting
consumption of energy-dense foods (such as cookies and cakes) and
avoiding sugary drinks to maintain a healthy weight. Scientists now say
that, after not smoking, maintaining a healthy weight is the most
important thing people can do for cancer prevention.
High blood
sugar levels — and weight — can be reduced by eating plenty of fruits
and vegetables and whole grains. Being overweight increases the risk of
six types of cancer, according to the AICR.
The study, part of
the Me-Can project looking at risk factors for metabolic syndrome,
looked at 274,126 men and 275,818 women from Norway, Austria and Sweden
who had an average age of 44.8. When they were followed up after 10.4
years, 18,621 men and 11,664 women had been diagnosed with cancer, and
6,973 men and 3,088 women had died of the disease.
For men, the
study found there were significant increases in risk of developing and
dying from cancers of the liver, gallbladder and respiratory tract.
There was also increased risk of developing thyroid cancer and multiple
melanomas and of dying from rectal cancer.
For women, there was
increased risk of both developing and dying from pancreatic cancer.
There was also increased risk of developing urinary bladder cancer and
of dying from cancers of the uterine corpus, cervix uteri and stomach.

Q & A
Q: Is shrimp off-limits if I have high blood cholesterol?
A:
No. Though higher in cholesterol than fish, shrimp doesn't contain as
much cholesterol as you might think — 190 milligrams in a 3/5 ounce
cooked serving (about 17 medium shrimp). That's about the same as in a
large egg, and within the daily limit of 200 milligrams of cholesterol
set by the American Heart Association for people with heart disease,
high cholesterol or other coronary risk factors. Moreover, some studies
suggest that shrimp's effects on blood cholesterol isn't all bad.
Saturated fat raises blood cholesterol more than dietary cholesterol,
and shrimp has virtually no saturated fat.
How you cook shrimp,
however, can add lots of calories and affect blood cholesterol. Instead
of breading and frying or broiling shrimp with butter or margarine, try
steaming or grilling. — UC Berkeley Wellness Letter, February 2010
RECIPE
French
toast doesn't have to be calorie-laden, as evidenced by this recipe for
Guiltless French Toast from Southern Living's 2009 Annual Recipes. It
uses egg whites and whole-grain bread.

1/4 cup fresh orange juice
1 tablespoon vanilla extract
1 teaspoon ground cinnamon
4 whole-grain bakery bread slices
1 tablespoon butter
1/4 cup maple syrup
Fresh blueberries and kiwi slices
Whisk
together first 4 ingredients in a shallow dish. Dip bread slices in egg
mixture, coating both sides. Melt butter on a griddle or in a large
nonstick skillet over medium heat. Place bread slices on hot griddle
and pour remaining egg mixture over bread slices. Cook 3 to 4 minutes
on each side or until golden.
Drizzle with maple syrup and top with fruit. Makes 4 servings.
