We know the effects of childhood traumas like abuse and neglect on later substance abuse. But what impact does second hand trauma have? A study published in the August issue of the journal Addiction shows that when a child under age 15 is exposed to a family member’s trauma (e.g.

Eating probiotics regularly may modestly improve your blood pressure, according to a new review of none studies examining blood pressure and probiotic consumption in 543 adults with normal and elevated blood pressure.

Probiotics are live microorganisms naturally occurring bacteria in the gut thought to have beneficial effects; they have recently been a nutrition trend and common sources are yogurt or dietary supplements. 


Too much dietary fat is bad for the heart, everyone knows that by now, but not all fats are equal. The right kind of fat keeps the heart healthy, and a paper in The Journal of Experimental Medicine shows how it works.

Unlike saturated fats discussed in popular media, unsaturated dietary fatty acids, such as eicosapentaenoic acid (EPA), are known to protect against cardiovascular diseases. However, the mechanism and the specific fat metabolites responsible for this protection were unknown. 


Spanish scientists did an experiment using obese rats and found that the consumption of probiotics over 30 days (equivalent to almost four years in human terms) helped diminish the accumulation of fat in the liver.


Last Friday a group of researchers announced their findings ahead of their report on the nutrition of organically produced food to be published in the British Journal of Nutrition.

An abdominal aortic aneurysm is a potentially life-threatening condition: If the body's major blood vessel ruptures, it can prove deadly.

Abdominal aortic aneurysms are a bulge in the aorta, which is the body's largest artery and is located in the abdomen above the belly button. The greatest risk is that the aneurysm will rupture.
That's scary but who should be watched?

The U.S. Preventive Services Task Force recently updated its recommendations on screening and Mayo Clinic vascular surgeon Peter Gloviczki, M.D., outlines how people are diagnosed and how surgery, which now includes a less invasive endovascular option, is improving survival rates


Donating a kidney is a selfless act and it is going to save a life.

But even before the Affordable Care Act, it had pitfalls if you wanted to add or change health insurance. In the future, the only option could be state Medicare programs, which many doctors are refusing to accept now.   Under the Patient Protection and Affordable Care Act, insurance companies can no longer refuse health insurance to live kidney donors or charge them a higher insurance rate. But, as with 'If you like your doctor, you can keep your doctor', the rules may change at any time, making donors stuck with nothing but government programs and the inability to get an appointment.

And insurance companies clearly penalize donors and have done so for decades.

If your baby is allergic to milk, your choices might get a little more narrow, if the European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) and the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition have their way.

In a commentary in the Journal of Pediatric Gastroenterology and Nutrition, they say that the inorganic arsenic levels of dietary products used by children should be regulated, and make the recommendation that "Rice drinks should not be used in infants and young children."


A new study suggests that experiencing stressful events the day before eating a single high-fat meal can slow metabolism in women.

Researchers questioned study participants about the previous day's stressors before giving them a meal consisting of 930 calories and 60 grams of fat. The scientists then measured their metabolic rate, how long it took the women to burn calories and fat, and took measures of blood sugar, triglycerides, insulin and the stress hormone cortisol.

On average, the women in the study who reported one or more stressors during the previous 24 hours burned 104 fewer calories than nonstressed women in the seven hours after eating the high-fat meal – a difference that could result in weight gain of almost 11 pounds in one year.


You don't have a pre-pregnancy and your computer doesn't have a pre-power switch. Calling someone who has moderately high blood sugar a prediabetic is premature and creates unnecessary alarm and financial burdens.

Imagine being at a party with gluten-free, HFCS-free, non-GMO, vegans who are now also pre-diabetic. Not fun. And worse, it has no value. A new analysis in BMJ sought to find out whether a "diagnosis" of pre-diabetes carried any health benefits such as improved diabetes prevention. If someone was going to get diabetes, treatments to reduce blood sugar only delayed the onset of type 2 diabetes by a few years and there was no evidence of long-term health benefits.
