Last week AICR joined the centennial celebration of the Academy of Nutrition and Dietetics – the US organization for food and nutrition professionals – at their annual Food and Nutrition Conference and Expo. We shared AICR’s cancer prevention research and education and chatted with hundreds of dietitians.
We also attended scientific sessions and heard some of the latest research on food and nutrition and health. Here’s a brief round-up from a few sessions focused on cancer:
Intermittent Fasting, Health and Cancer
Intermittent fasting means alternating one or more normal eating days with at least one day of fasting and is a hot topic in health research. Here researchers presented evidence on overnight fasts of at least 13 hours and how that might affect weight, metabolic health and perhaps cancer risk, including these 2 studies: Read more… “Nutrition research round-up: News from food, nutrition conference”
The American Institute for Cancer Research has a new Director of Research, Nigel Brockton, PhD, and we’re looking forward to all the expertise he brings.
Dr. Brockton has first-hand experience with cancer, being diagnosed in his final year of high school and then his cancer returned while an undergraduate studying marine biology in Scotland. He then shifted to cancer research, graduating with a PhD in genetic epidemiology. Here, Dr. Brockton shares his passion for the field of cancer prevention and survivorship, along with how AICR has intertwined with his work.
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.
