Federal funding for obesity-nutrition research shoots up

Federal funding for obesity-related nutrition research has grown more than seven-fold over a 25-year period as food science research has nudged downwards, according to a recent government report. The number of projects rose from 78 in 1985 to 577 projects by 2009.

Nutrition research in food science, which includes food processing/preservation, has decreased from 226 projects in 1985 to 177 projects.

The figures and chart stem from a USDA report that came out earlier in the year that analyzed federally supported nutrition research from 1985 through 2009 (the latest year of available USDA data). Other findings from the report include: Continue reading


Review: plenty of health reasons to get those young kids active

If being active is good for you — and you know it is — how important is it for young kids? Very, suggests a new review of the research out of the United Kingdom. The review points to how running about and playing sports as children links to numerous health benefits, many of which relate to lowering cancer risk decades later as adults.

For the review, researchers at the British Heart Foundation for Public Health England, part of the UK’s Department of Health, looked at how activity improves 5- to 11-year-olds mental, physical and long-term behaviors.

After finding then rating the studies, the review found strong evidence that activity helps kids’ cardiometabolic health, which puts them at lower risk to develop type 2 diabetes, obesity and other issues related to poor metabolic health. These studies generally focused on how physical activity linked to risk factors for chronic diseases, such as insulin levels and markers of inflammation. Many of these risk factors for heart disease and type 2 diabetes are also shared factors for increased cancer risk.

Here’s the PDF of the evidence review, and below is the summary of what they found.

Study: Obesity Increases Breast Cancer Risk, Preventing Weight Gain Key

Postmenopausal women who are overweight — and especially obese — have a greater risk of developing breast cancers, finds a new study that highlights the importance of preventing weight gain, as it also raises questions about whether losing weight necessarily reduces that risk.

The study adds to a consistent body of research showing that overweight and obesity increases women’s risk of postmenopausal breast cancers. It was published yesterday in JAMA Oncology.

AICR estimates that a third of US breast cancers could be prevented if women were at a healthy weight throughout life, were active and did not drink alcohol.

In this study, as other research has seen, the heavier the women, the greater the risk. Women categorized as the most obese were at almost double the risk of the most common type of breast cancer, ER-positive, along with PR-positive tumors. These cancers are fueled by the hormones estrogen and progesterone, respectively.

The study used data from approximately 67,000 women who were all part of the Women’s Health Initiative trials. That study focused on preventing certain cancers, heart disease and osteoporosis. When the women entered the study in the mid 1990s they were 50 to 79 years old, and they were weighed. They also answered questions about their lifestyle habits, medical history and other health risk factors. After that, they were weighed annually and had regular mammograms. Continue reading
