Children who ate oranges and bananas or drank orange juice most
days of the week before age 2 were significantly less likely than
other children to be diagnosed with leukemia before age 14,
according to research released this month. Previous research has
suggested that diet may influence the risk of certain cancers,
including colorectal, prostate, lung and breast cancers.
Before age 15, more children become sick from leukemia than from
any other type of cancer. But until now, the effect of diet on
the childhood risk of this cancer was largely unknown.
University of California medical investigators interviewed the
mothers of 328 children diagnosed with leukemia and the same
number of cancer-free kids. Mothers reported what children ate
before age 2.
The researchers found that children who ate oranges or bananas
4-6 times per week were around half as likely to develop leukemia
before age 14. Drinking orange juice 4-6 times per week reduced
leukemia risk by a comparable amount.
In contrast, cured meats such as lunch meats and hot dogs contain
substances that can become carcinogenic in the stomach. Research
in rats suggests that eating these meats in pregnancy may
increase the risk of brain tumors in offspring.
However, in this report, eating hot dogs or lunch meats had no
influence on leukemia, perhaps because vitamin C, along with
other vitamins and nutrients contained in fruit, protect the body
from the damage the meats can cause, according to the
This study illustrates the critical importance of feeding your
child plenty of fresh vegetables and fruit. Do not feed your
child “convenience foods” such as cured meats, hot dogs, French
fries, etc. Leukemia is only one of many health risks you can
reduce in your child with a healthy diet.
