DID YOU KNOW that excessive smartphone use, particularly among young people, may lead to a decrease in physical activity?
In a recent study presented at the American College of Cardiology Latin America Conference 2019, university students who used their smartphones five or more hours a day had a 43 percent increased risk of obesity, and were more likely to have other lifestyle habits that increase the risk of heart disease.
Participating students were twice as likely to drink more sugary drinks, fast food, sweets, snacks and have decreased physical activity. Twenty-six percent of the subjects who were overweight and 4.6 percent who were obese spent more than five hours using their device.
ZANTAC UPDATE
Many of you asked about the form and dosage of Pepcid as a short-term replacement for Zantac. We only recommend the 10 milligram Pepcid AC Original Strength tablet once or twice daily maximum. Take 15 to 20 minutes before eating. *Please note this product DOES NOT contain cornstarch so is okay for corn intolerant individuals.
LOSARTAN ISSUE
The same carcinogenic chemical that is plaguing Zantac has plagued blood pressure medication for months now. The FDA just released new information on how Losartan is being affected.
LOW D MAY MEAN LOW T AND MORE
Steve and Bonnie: Three very compelling studies show how genetic predisposition can lead to low vitamin D levels, which in turn, can lead to adverse health.
Low Vitamin D May Mean Low Testosterone In a new study from Journal of Clinical Endocrinology & Metabolism, authors examined a link between low vitamin D levels and lower total testosterone levels. Excitingly, researchers looked at mutations of vitamin D genes that we screen for in our Pure Genomics evaluation. The higher genetic risk score for low vitamin D (largest number of mutations), the lower the risk of vitamin D levels. Of those with lower vitamin D levels, the risk for low testosterone was significantly elevated. The next step is to directly study optimal vitamin D levels with testosterone levels. This is important because optimal testosterone is just as important for women as it is for men. Vitamin D for Colorectal Cancer Protection An investigation of vitamin D-related genes, blood vitamin D levels, and colorectal cancer risk appeared recently in Nutrients. Researchers purport that genetic variants are associated with colorectal cancer depending on vitamin D levels. The least number of genetic mutations and higher vitamin D levels were found to be associated with the lowest risk for colorectal cancer. Even with mutations in the VDR, GC, and CYP27B1 genes, when blood vitamin D levels were optimal, colorectal cancer risk was low. Vitamin D Deficiency and Early Mortality
New research presented at the Annual Meeting of the European Association for the Study of Diabetes revealed that vitamin D deficiency is strongly linked to increased mortality. Researchers analyzed data from the records of 78,581 patients (average age 51.0 years) who had a vitamin D measurement taken between 1991 and 2011, which was then matched with the national register of deaths. Patients were followed for up to 20 years where possible, with a median follow-up of 10.5 years. The survival data confirm a strong association of vitamin D deficiency (under 50 nmol/L) with increased mortality. This association is most pronounced in the younger and middle-aged groups and for causes of deaths other than cancer and cardiovascular disease, especially diabetes. The findings strengthen the rationale for widespread vitamin D supplementation to prevent premature mortality and emphasize the need for it early in life. Interestingly, there was no risk resurgence in those with vitamin D levels above 100 nmol/L. The authors say this further diminishes concerns about a possible negative effect of vitamin D in the higher concentration range, as have been shown in some previous studies reporting "inverse J-shaped" risk association (meaning risk decreased to a certain level of vitamin D and then started increasing again at higher levels).
