Medical notes this week…
Osteoarthritis, sometimes called “wear and tear arthritis,” is the biggest cause of disability in the United States. Now a new study suggests that wear and tear may not be the cause. It might be a bad balance of bacteria in the intestines. The study in the journal JCI Insight shows that mice fed a high fat diet developed bacteria in the gut that were dominated by pro-inflammatory types. The mice developed inflammation all over their bodies and rapid deterioration of joints. But when they were given a prebiotic to balance the intestinal bacteria, it reversed the symptoms.
Some experts have suggested drinking coffee to prevent Alzheimer’s disease. But a new study shows that once Alzheimer’s has taken hold…coffee or other caffeinated drinks only make the symptoms worse. The animal study in the journal Frontiers in Pharmacology shows that caffeine increases anxiety and fear of new things two hallmarks of Alzheimer’s that are considered strong sources of distress for patients. It took the equivalent of about three cups of coffee per day to produce the effects.
And finally… if you work the night shift, or if your work changes hours often, watch out for that cheeseburger on the way home. a study in the FASEB Journal shows that constantly changing schedules make it tough for the body to process fats without producing much higher than normal levels of inflammation.
