A new report out today shows US adult obesity rates leveling off, yet still at least one of every four adults has obesity in almost every state. That’s a big deal for cancer risk because AICR research links obesity to eleven cancers. Aside from not smoking, getting to and staying a healthy weight is the single biggest change people can do to lower their cancer risk.
Only 40 percent of babies meet the global recommendations for breastfeeding, according to a report released today to mark the start of World Breastfeeding Week.
As the analysis points out, there are many health benefits for breastfeeding – including cancer protection. AICR’s latest report found that breastfeeding lower the risk of breast cancer for mothers. Previous research suggests that babies who are breastfed are less likely to gain excess weight as they grow. Among adults, overweight and obesity increases the risk of 11 common cancers, including colorectal, ovarian and post-menopausal breast.

The evidence is not clear on how – or even whether – snacking, breakfast eating or meal size links to weight. A large study adds new data to this body of research suggesting that fewer daily meals and snacks can help prevent weight gain, at least for this healthy group. For cancer prevention, staying a healthy weight is key to reducing risk for many common cancers like endometrial, postmenopausal breast and colorectal.
The authors analyzed data from the Adventist Health Study that includes over 50,000 North American adults. At the beginning of the study, participants reported their height and weight, as well as health habits like exercise, sleep and television watching. They also reported their eating habits via 24 hour recalls and a food frequency questionnaire.
The participants – members of the Seventh Day Adventist Church – tend to be more health-conscious, nonsmokers, mostly nondrinkers and eat less meat than most Americans.
Researchers used this data to determine how many meals – including snacks and breakfast – participants ate, and which meals were typically largest. They calculated participants’ weight changes by comparing Body Mass Index (BMI) at the beginning and end of the study.
An average of 7 years later, the study found:
For participants eating 1 or 2 meals a day, their BMI decreased in comparison to those eating 3 meals per day.
