Thanks for visiting! My goal here is to discuss the latest scientific research to separate the good from all that "guff" in nutritional sciences and all aspects of human health. Because the more you Know, well...the more you Know!

Newly Discovered Mechanism of Action for Probiotics

A new research study on the popular probiotic strain called Lactobacillus rhamnosus GG shows that probiotic bacteria may work by a mechanism not previously known. While evidence of the benefits of Lactobacillus rhamnosus GG (LGG) for intestinal problems , respiratory infections and eczema have previously been identified by scientists, the key mechanism underlying this effect has been unclear.


Probiotics Help You Forget

An old boss once jokingly told me that "the secret to happiness is 1) lots of money, and 2) a bad memory." I joked back... "well, then I'm halfway to happiness and just need that money to start rolling in!"

We all know that dwelling on previous negative experiences (known as rumination) can activate negative dysfunctional patterns of thinking, which are triggered by subtle changes in mood (known as cognitive reactivity), is one of the most predictive risk factors of depression. This newly published study examined the effects of supplementation with a multispecies probiotic product on rumination and cognitive reactivity.


Pesticides Increase Risk of Heart Attacks

Happy Earth Day! As such, I'll discuss another recent study related to the environment. A month ago I covered a ground-breaking study that showed the use of common pesticides/herbicides cause pathogenic bacteria to develop antibiotic resistance (click HERE for that discussion). Now this new study shows that pesticide exposure could contribute to an increased risk for heart attacks and inflammation in obese premenopausal women.

This study on women demonstrated that endocrine-disrupting chemicals, and not necessarily obesity itself, could play a role in the later development of heart conditions.


Marijuana Use Lacks Long-Term Negative Consequences

Well, it's April 20th, a celebratory or sacred day for those who are pro-marijuana (whether for recreational, medical, or spiritual use). So as appropriate for this day, I share with you a new study that contradicts the long-held belief that marijuana use during our teen years has long-lasting negative cognitive health effects.


Chemical Exposure May Lead to Early Menopause in Women

A recent study has shown (again) that women who have the highest levels of endocrine-disrupting chemicals (EDCs) from a wide variety of common household and personal-care products enter menopause anywhere from 1.9 to 3.8 years earlier than those who have lower levels of EDC.

"Even menopause a few years earlier than usual could have a significant effect on bone health, on cardiovascular health, on memory and quality of life for women in general," said the senior author. "But I think the bigger question--and one that warrants further research--is what's happening at the other end of the ovarian health spectrum. Is the age at which we get pregnant shifting earlier as well, so there are other events on the spectrum that we need to address?"


New Study on Kimchi

A new study has shown that consuming fermented kimchi (a source of lactobacilli bacteria), may alter the intestinal microbiome (composition of bacterial populations in the gut) and affect metabolic pathways for obese women.

In this eight-week study, daily kimchi consumption was associated with a significant reduction in the ratio of Firmicutes to Bacteroidetes in obese women (this ratio is reportedly a good biomarker for obesity).
