Consuming xylitol does prevent cavities despite recent uncertainty over its anti-caries properties, according to a DuPont study.

Doubt was cast on the natural sweetener’s anti-caries effect last year when a Cochraine review declared there was little evidence. The review included data from over 5,900 subjects using xylitol-based lozenges, sweets, toothpastes, syrups, and tooth-wipes.

However, using an in vitro dental simulator with artificial saliva, DuPont believes it has proven that xylitol is protective against tooth decay because it lowered gram-positive bacteriaStreptococcus mutans (S. mutans) – a known cause of cavities.

A group of doctors and medical researchers have backed olive oil as a heart-healthy food, while raising concerns about fad diets and the use of coconut and palm oils.

A new analysis of nutrition studies voices support for olive oil as a heart-healthy substitute for butter, while urging consumers to avoid coconut and palm oils.

"The evidence base for olive oil is the most comprehensive, with clear evidence for a benefit in cardiovascular risk reduction." - Journal of the American College of Cardiology

New data from human clinical study with Yestimun show significantly increases in joy and decreased blood pressure. These results from Leiber's newest clinical study with Yestimun® have recently been published in the Journal of the American College of Nutrition.

New clinical research simulating neuronal activity, conducted by the Division of Life Science, Hong Kong University of Science and Technology, shows that PCSO-524® (the active ingredient in Lyprinol®), protects cells under toxic inflammatory challenge. The researchers noted the promising potential of PCSO-524® to postpone or prevent the onset of neurodegenerative diseases like Alzheimer.
