Chewing More May Boost Brain Health and Memory, Research Suggests

Chewing More May Boost Brain Health and Memory, Research Suggests A controversial idea that is gaining support A long time ago, American nutrition advocate Horace Fletcher became famous for his extreme chewing habit. He claimed food should be chewed until it turns almost liquid. He even believed this could reduce food intake and save money at a large scale in society. His methods were unusual, but modern researchers say he was not entirely wrong. How chewing affects the brain Experts now suggest that chewing more than usual may do more than help digestion. It can also support brain function. Studies indicate that stronger chewing activity increases blood flow to the brain, which may improve attention, focus, and memory performance. Researchers also link good oral health with lower risks of cognitive decline. Some studies suggest a connection between tooth loss, gum disease, and conditions like dementia and Alzheimer’s disease. While chewing is not a treatment, it may play a supporting role in keeping the brain active. The science behind mastication Chewing is not just a mechanical step in eating. It activates muscles in the jaw that increase blood circulation and stimulate parts of the nervous system. According to scientists studying human evolution, our jaws and teeth have changed over millions of years, which may also influence how we process food and energy today.

Previous Article John Travolta’s Cannes Directorial Debut Divides Critics After Mixed Reception Cannes Premiere Draws Mixed Reactions John Travolta has made his first step behind the camera with Propeller One Way Night Coach, which premiered at the Cannes Film Festival. The screening was introduced by festival director Thierry Frémaux, who noted that films made by actors often feel personal, inventive, and closely tied to cinema itself. Despite that framing, early reactions to the film have been far from positive. One critic described it bluntly as a “disaster”, setting the tone for a divided critical response. A Short, Personal Story Told Through Memory The film is a deeply personal project for Travolta. It follows a young boy traveling with his mother on a domestic flight across the United States in the 1960s. The journey includes brief stops in different cities, but the narrative stays minimal and reflective rather than plot driven. Travolta first wrote the story as a children’s book in 1997. The film version keeps that same simplicity, running for just over an hour and relying heavily on voiceover narration instead of traditional dramatic scenes. Actor to Director Shift Raises Familiar Questions Travolta joins a long list of actors who later stepped into directing. Some have succeeded, while others have struggled to replicate their on screen impact behind the camera. History shows mixed results. Films by established actors often appear at major festivals like Cannes or Toronto, then fade quickly from public attention. Recent examples include Ryan Gosling’s Lost River and Chris Pine’s Poolman, both of which received weak critical responses and limited follow up projects. At the same time, there are clear success stories. Figures such as Charlie Chaplin, Clint Eastwood, Greta Gerwig, and Jordan Peele have built strong directing careers. This contrast highlights how difficult the transition can be, even for major stars. Festival Spotlight but Uncertain Future Some industry observers question whether festival selection always reflects quality or simply the appeal of celebrity names. Travolta’s film, with its autobiographical tone and experimental structure, fits into a pattern of passion projects that gain festival attention but struggle to find wider audiences. At just 61 minutes, the film feels more like a personal memory piece than a mainstream release. Its heavy use of narration and limited dramatic structure further sets it apart from conventional storytelling. John Travolta’s Cannes Directorial Debut Divides Critics After Mixed Reception

Australian shark attack near Rottnest Island leaves father of two dead Incident at Horseshoe Reef An Australian man lost his life after a shark attack while spearfishing off Western Australia. The incident took place around 10:00 local time at Horseshoe Reef, northwest of Rottnest Island near Perth. The victim, Steven Mattaboni, aged 38, was in the water with friends about 1 kilometer from shore when a large shark, estimated around 4 meters long, bit him on the lower leg. Rescue attempt by friends Friends quickly brought him back to shore after the attack. Emergency teams arrived soon after, but they were unable to save him. Police described the event as a severe and distressing attack. Officers confirmed that witnesses saw the full incident unfold. Family statement and personal tribute His wife, Shirene Mattaboni, described him as a loving father and devoted partner. She said he deeply cared for their two young daughters, including a baby aged four months and another child turning three next month. She shared that he loved the ocean and spent much of his time fishing. She described him as generous, loyal, and kind, saying the family feels deep grief after the sudden loss. Tributes from community and sport club The Kingsley Amateur Football Club in Perth paid tribute to him, remembering him as a valued member and a friend to many. The club said he was known for his warm personality and positive presence. The Australian Underwater Federation also expressed sympathy. Its president noted that spearfishing carries risks, even though safety measures are used in organized settings such as boats and shark spotting systems. He added that recreational diving can leave people more exposed because conditions are less controlled. Official police details WA Police Sergeant Michael Wear said the attack happened while Mattaboni was close to his boat, about 20 meters away at the time. Friends witnessed the incident and immediately tried to help. Authorities continue to remind the public about ocean safety risks in shark active waters.
