Eat Lots of Fiber to Improve Melanoma Outcomes
A new type of immunotherapy that enables T-cells to fight cancer cells is proving hopeful for people with the deadly skin cancer melanoma, and a new study has found that a high-fiber diet improves the effectiveness of the therapy. Researchers from the University of Texas MD Anderson Cancer Center reported in Science that, by analyzing the gut microbiome in hundreds of patients, they found that higher dietary fiber intake was linked with disease non-progression among patients receiving immune checkpoint blockade therapy compared to patients eating little fiber. The results were strongest in patients that ate the most dietary fiber, but did not take probiotics, a finding that was replicated with lab animals.
Consider Berberine and Probiotics to Improve Cholesterol When used together, the plant alkaloid berberine and the probiotic Bifidobacterium breve work synergistically to significantly improve total cholesterol and low-density lipoprotein cholesterol levels, reports a new study in Gut Microbes from Shanghai Jiao Tung University, in China. Researchers tested 365 diabetes patients at 20 centers throughout the country, giving them either a placebo, one of the two substances or both. Comparing post-meal blood samples after 12 weeks, patients that had taken both the berberine and the probiotic had significantly better cholesterol readings and experienced positive changes in the gut microbiome, as well as better fatty acid metabolism. 12

Avoid Formaldehyde to Sidestep Cognitive Problems Workers exposed over years to formaldehyde may experience thinking and memory problems later in life, researchers at the University of Montpellier, in France, have concluded. Their study published in the journal Neurology surveyed and tested more than 75,000 people with an average age of 58. Of those, 8 percent were exposed to formaldehyde through their occupations as nurses; caregivers; medical technicians; workers in the textile, chemistry and metal industries; carpenters and cleaners. The risk of developing thinking and memory problems was an average of 17 percent higher in people that were exposed to formaldehyde on the job than those with no such exposure. People exposed to formaldehyde for 22 years or longer had a 21 percent higher risk of cognitive impairment.
Try Fenugreek to Boost Male Fertility and Health Fenugreek, an herb used in Indian curries and Middle Eastern cuisine, has been shown in studies to increase breast milk production in women, and a 12-week study of 100 men has found that it also boosts male testosterone and fertility. A research team at King George’s Medical University, in Lucknow, India, gave 500 milligrams a day of an extract made from fenugreek seeds to men that ranged in ages from 35 to 60. Sperm motility, or movement, significantly increased at eight and 12 weeks of treatment, while abnormal sperm morphology significantly decreased at 12 weeks. Testosterone levels, cholesterol markers and libido also improved. Higher levels of alertness were documented, along with lower blood pressure.
