Inflammation's trigger finger
A molecule found in nearly all cells plays a vital role in kick-starting the production of key biological molecules involved in inflammation, a group of Salk Institute scientists has discovered. The finding, published in the June 25 issue of Science, may lead to new strategies for blocking the devastating inflammation that lies at the heart of autoimmune disorders such as multiple sclerosis, arthritis, lupus as well as some cancers.  more

Cholesterol levels, diabetes, & hypertension – known risk factors for strokes & heart attacks – can contribute to risk of cognitive decline and dementia later in life
Higher levels of "good" cholesterol in middle age may help preserve brain function in later years, according to research reported today at The 9th International Conference on Alzheimer's Disease and Related Disorders (ICAD), presented by the Alzheimer's Association.  more

A longer chain fatty acid, found in milk and beef products, is found to increase key peptide production and reduce appetite and energy intake
It appears that size matters when it comes to the length of the macromolecule found in fatty acids and the effect on appetite suppression. Researchers have determined that the longer the molecular chain, the more effective the fatty acid is in increasing important peptides associated with digestion. The reason is found in the actions of nutrients within the digestive system. more
