Permanent hair dye and straighteners may increase breast cancer risk

By National Institutes of Health (NIH)

Scientists at the National Institutes of Health found that women who use permanent hair dye and chemical hair straighteners have a higher risk of developing breast cancer than women who don’t use these products. The study published online Dec. 4 in the International Journal of Cancer and suggests that breast cancer risk increased with more frequent use of these chemical hair products. Using data from…

We May Not Have to Age So Fast

By David A. Sinclair and Matthew D. LaPlante

We all age chronologically with the passage of time, but what about our bodies? Is physiological aging inevitable too? A growing cadre of biologists is starting to say no, thanks to developments in the field of epigenetics, which studies not our DNA itself but the processes that determine how our genes “express” themselves in directing our cells throughout our lives. If you think of your…

The Link Between Diet, Exercise and Alzheimer’s

By Sumathi Reddy

In his 40s and a self-described fitness nut, Stephen Chambers doesn’t seem like someone who would be worrying about Alzheimer’s. But when his father was diagnosed with the disease about five years ago, he went to the Alzheimer’s Prevention Clinic in New York to see what he could do. Continue reading at The Wall Street Journal

Key molecule linked to cancer cell metabolism in tumours of the nervous system

By Cheryl Xia

Researchers discover a key player in tumor energy metabolism that holds promise for new cancer treatments with fewer side-effects. Tumours are characterized by uncontrolled cell growth, which is sustained by a series of cellular reactions to produce the energy and molecular building blocks for replication. This process, called cancer cell metabolism, relies on the activity of many proteins and enzymes involved in metabolic pathways. Scientists…

Diet for One? Scientists Stalk the Dream of Personalized Nutrition

By Cynthia Graber and Nicola Twilley

No single food regimen works for everyone. A new study is the most comprehensive effort yet to understand why. A decade ago, spurred by the success of the Human Genome Project and the affordability of genetic sequencing, scientists began to explore the promise of “nutrigenomics.” Could personalized nutrition, informed by knowledge of an individual’s DNA, help prevent and even treat diet-related diseases? The results of…

9 Extremely Subtle Signs You Have Too Much Inflammation in Your Body

By Carolyn Steber - Bustle

If you’re experiencing signs your body has inflammation, it can crop up in the form of various symptoms, and be a sign of a number of different health concerns. Usually, inflammation is associated with joint health, since arthritis is one of the top causes of pain and swelling. But inflammation can be associated with other health concerns, beyond swollen joints. While you’ll want to tell…

‘Ultraprocessed’ foods may make you eat more, clinical trial suggests

By Health - AAAS

Something about the industrial processing of food makes us more likely to overeat, according to a new study. Volunteers ate more and gained more weight on a heavily processed diet than an unprocessed one, even when the two diets had the same available calories and nutrients. The study is “a landmark first,” and a “shot over the bow” in a debate over the health of…

Raw and Red-Hot

By Harvard Magazine

Could Inflammation be the Cause of Myriad Chronic Conditions? In 2007, associate professor of medicine Samia Mora and colleagues published a study of exercise that sought to understand why physical activity is salutary. They already knew that exercise reduces the risk of cardiovascular disease as much as cholesterol-lowering statin drugs do. By analyzing biomarkers in the blood of 27,055 women participating in a long-term study,…

Interview – Identifying Food Sensitivity and Intolerance

By Cell Science Systems

“When it comes to testing, you can always count on a lively debate about how to best identify food sensitivity and intolerance. In this interview we review recent clinical and mechanistic research on the Alcat test, including studies conducted by Yale School of Medicine and other institutions. In addition, general advice will be given about how food testing can help integrative practitioners create personalized diets…
