3 Ideas for Better Habits
Gut Harmony
Nutritional psychiatrist Dr. Uma Naidoo explores how gut health directly influences mood, memory, and focus.
“Prebiotics are essentially food for helpful bacteria, certain types of fiber that we cannot digest but the good bacteria in our guts can. For probiotics to be effective, it is helpful for them to have prebiotic foods available in the gut to digest. Probiotics break down prebiotics to form short-chain fatty acids that help reduce gut inflammation, block the growth of cancerous cells, and help the growth of healthy cells.”
Hearts & Minds
Psychiatrist Dr. Drew Ramsey reveals that nutrition plays a powerful role in emotional stability and resilience.
“Psychiatric medicine and mental healthcare have a serious problem. Experts around the globe - from the World Health Organization to the Pew Research Center - all agree: we are in the midst of a mental health epidemic. Diagnoses of depression and anxiety disorders have snowballed over the past decade, now occurring more frequently in teens and young children.”
Eat Smart, Think Sharp
Neuroscientist Lisa Mosconi examines how diet impacts brain performance, hormone balance, and cognitive decline.
“Overall, the typical Western diet is the opposite of “brain healthy.” Time to roll up our sleeves and address this issue once and for all.”
