Professor Andrew Smith of Cardiff University's School of Psychology, tested a group of volunteers over a four week period. Measures taken at baseline showed that those that regularly consumed a high-fiber diet were less emotionally distressed; had fewer cognitive difficulties; had a more positive mood; had less difficulty falling asleep and had lower depression scores than those people who ate a low-fiber diet.
The results from the intervention showed that those who included Kellogg’s All-Bran and Kellogg’s Bran Flakes reported a 10 per cent reduction in fatigue.
Professor Smith commented, “The physical benefits of a high-fiber diet have been widely acknowledged amongst healthcare professionals for many years, however this is the first time high-fiber intake has been associated with improved mental health.”
Dr. Kathryn O’Sullivan, Head of Nutrition Affairs at Kellogg’s, says: “This new study is very important and reveals that a bowl of high-fiber cereal is now scientifically shown to have a great impact on physical and mental well-being”.
“Eight out of ten people do not eat enough fiber and are forfeiting the emotional and physical benefits that fiber is proven to provide.”
Kellogg’s All-Bran and Kellogg’s Bran Flakes are extremely rich sources of natural grain fiber. For example, one bowl of Kellogg’s All-Bran provides over 50 per cent of daily fiber needs, which is as much as five slices of whole meal bread or seven bowls of brown rice.
