Data analysis reveals link between age of puberty onsite and health in later life

Data analysis reveals link between age of puberty onsite and health in later life.

From the 18 June 2015 Guardian article

The age that children hit puberty has been found to be a significant predictor of their health in later life, researchers say.

The University of Cambridge study confirms previous findings of a link between early puberty in women and heart disease and type 2 diabetes, and has shown for the first time that early puberty in men is also associated with these conditions.

Those who went through puberty relatively early had around 50% higher relative risks for type 2 diabetes and heart disease. However, women and men who went through puberty relatively late had a higher relative risk of developing asthma.

Researchers from the Medical Research Council (MRC) epidemiology unit at theUniversity of Cambridge found that the age at which both men and women begin puberty is associated with a total of 48 different health conditions including irritable bowel syndrome, arthritis, glaucoma, psoriasis and depression – along with early menopause in women.

Why Some Fats Are Worse Than Others

All dietary fats are not created equal. Some types of fats have been linked to ailments like heart disease and diabetes, while others, like those often found in plants and fish, have well documented health benefits.

So why do our bodies respond so destructively to some fats but not others?

A new hypothesis described in latest issue of The Quarterly Review of Biologysuggests the answer may lie in how different fats interact with the microbes in our guts. According to researchers from the University of New Mexico and Northwestern University, some fats may encourage the growth of harmful bacteria in the digestive system. Our bodies have evolved to recognize those fats and launch an immune response to preempt the impeding changes in harmful bacteria. The result is low-levelinflammation that, over the long term, causes chronic disease.

“Although the inflammatory effects of [fats] are well documented, it is less well appreciated that they also influence bacterial survival and proliferation in the gastrointestinal tract,” write the researchers, led by Joe Alcock, of the University of New Mexico Department of Emergency Medicine and VA Medical Center.

Some fats – mostly unsaturated fats – actually have strong antimicrobial properties. They react chemically with bacterial cell membranes, weakening them. “If you expose unsaturated fats on bacteria, the bacteria have a tendency to lyse. The combination of long chain unsaturated fats, especially omega-3 fatty acids, and innate host defenses like gastric acid and antimicrobial peptides, is particularly lethal to pathogenic bacteria,” Alcock said. Saturated fats on the other hand generally lack those antimicrobial properties, and in fact can provide a carbon source that bacteria need to grow and flourish….
