Childhood Obesity linked to Colorectal Cancer

Researchers from Tel Aviv University have found that children classified overweight or obese (BMI percentile ≥ 85) have a 50% higher chance of developing urothelial or colorectal cancers in adulthood compared to those with a BMI less than 85.

During this study, the researchers looked at a group of 1.1 million males in the Israeli Defense Forces over an 18 year time span. After controlling for factors such as year of birth and education, the researchers discovered this clear link between childhood BMI and those who were diagnosed with urothelial or colorectal cancers later in life.

And it might not just be bladder & colon cancers.

Researcher Dr. Ari Shamiss “believes that further research will reveal connections between childhood obesity and a wide range of other cancers, including pancreatic cancer, which he is currently researching”.

What does this mean to you?

According to Dr. Shamiss, more research needs to be done to determine if “whether or not a successful weight loss attempt can reduce a child’s risk of developing urothelial or colorectal cancer in adulthood. Their current sample looks at children who were obese and those who were of normal weight, but does not reveal whether weight loss makes a significant difference”.

New research should focus on researching the pathogenetic link between obesity and cancer, and whether losing weight in adulthood could lower the risk, Dr. Shamiss says.

My opinion?

  • Without getting paranoid about a bit of baby fat, parents need to start thinking of how the food they feed their children impacts their health….and it goes way beyond cancer.
  • Heart disease, diabetes, mental health, etc….all of these medical conditions are impacted by the food & drink we put into our bodies.
  • Candy and cookies and potato chips and pizza may put a smile on your kid’s face…but it’s doing the opposite to their organs.

It’s time to step up and start acting like a parent.
