Scientists bioengineered a lablab bean gum containing an antiviral protein that cuts HPV levels by up to 93% in saliva and, when fortified with protegrin, nearly eliminates two cancer-associated oral bacteria (Pg and Fn), suggesting use as an adjuvant therapy or preventive measure for squamous cell carcinoma of the mouth and throat while preserving beneficial oral microbes.
Researchers from the University of Pennsylvania developed a lablab-bean–based bioengineered chewing gum that releases FRIL antiviral protein and Protegrin antimicrobial peptide to reduce HPV levels (up to 93% in saliva) and two cancer-linked bacteria (Porphyromonas gingivalis and Fusobacterium nucleatum) in lab tests, while largely sparing beneficial oral bacteria. The gum is not yet publicly available and is not a substitute for HPV vaccination, regular screenings, or medical treatment; more clinical trials are needed to determine whether regular use could lower cancer risk or improve outcomes.
A study in the British Journal of Clinical Pharmacology found that chewing sugary gum for several hours after consuming nitrate-rich vegetables (like beets, spinach, and kale) increases mouth nitrite and systemic nitrite, which can temporarily lower blood pressure. The effect is short-lived and while it may aid endurance or post-meal BP, sugary gum carries dental health risks and isn’t a substitute for medical BP management.
Researchers have developed a chewing gum made from lablab bean proteins that could help fight head and neck cancer by reducing oral microbes linked to the disease. In ex vivo tests, the gum lowered HPV levels by about 93% in saliva, and when bioengineered to include an antimicrobial peptide, it nearly eliminated Porphyromonas gingivalis and Fusobacterium nucleatum without disturbing beneficial mouth bacteria. The approach targets infection locally at the site of cancer risk and could complement existing therapies. Trials are being planned in London and at the University of Pennsylvania in the U.S. to evaluate its effectiveness in HNSCC patients.
Ancient birch tar used as chewing gum 6,000 years ago reveals insights into Neolithic gender roles, diet, and practices through preserved human and microbial DNA, showing differences in usage between males and females and offering a unique window into prehistoric life.
DNA extracted from 10,000-year-old chewing gum found in Sweden sheds light on the Stone Age diet and oral health of teenagers, revealing that they consumed deer, trout, hazelnuts, apple, duck, and fox. The gum, made of birch bark pitch, also showed signs of severe periodontitis in one teenage girl, indicating poor oral health. This discovery provides valuable insights into the lives of ancient hunter-gatherers and their daily activities.
Analysis of chewed resin from Stone Age teenagers at a site in Sweden has provided insights into their lives 9,700 years ago. DNA analysis of the resin revealed human DNA, indicating the presence of teenagers of both sexes. The resin also contained DNA from bacteria, fungi, red deer, brown trout, hazelnuts, and possibly fox. The study suggests that the teenagers were using the resin for tool making and recreational or medicinal purposes. The analysis also indicated that one of the teenagers likely suffered from severe gum disease. This research provides valuable information about the lifestyle and health of Stone Age people and opens up new possibilities for understanding ancient cultures through DNA analysis.
Analysis of 10,000-year-old chewing gum found in Sweden reveals that Stone Age teenagers had a diet consisting of deer, trout, nuts, and various animal species, and suffered from poor oral health, including gum disease and tooth decay. The gum also contained DNA from plants and animals, indicating their consumption and use of teeth for processing. The findings provide insight into the lives of Mesolithic Scandinavians and suggest the use of mistletoe for medicinal or poison production for arrowheads.
Ferrara has discontinued the iconic chewing gum brands Fruit Stripe Gum and Super Bubble, citing declining gum sales and changing consumer preferences. The decision marks the end of decades-long runs for both brands, with remaining supplies still available in some stores until they are sold out. Fruit Stripe Gum, known for its colorful packaging and zebra mascot, was popular for its five flavors and zebra-themed tattoos, while Super Bubble was the first individually-wrapped bubble gum introduced to kids in 1946.
Ferrara Foods has announced the discontinuation of the iconic Fruit Stripe gum after more than 50 years, citing it as a "difficult decision" and attributing it to factors such as consumer preferences and purchasing patterns. The brightly flavored gum, known for its rainbow packaging and cartoon zebra, has been a nostalgic favorite since the 1960s, but fans have expressed disappointment and nostalgia on social media, with some lamenting the loss of a piece of their childhood.
A dentist has shared tips on how to enjoy chewing gum without damaging your teeth. Dr. Ellie Phillis recommends avoiding gum sweetened with sorbitol and opting for 100% xylitol gum instead. Xylitol gum has a hygroscopic property that stimulates saliva production, mineralizing teeth and helping gums heal. Dr. Phillis advises chewing xylitol gum for up to 15 minutes and then discarding it appropriately to avoid changing the composition of saliva. She also suggests avoiding gum with glycerin and provides insights on tooth sensitivity, plaque buildup, and other oral health topics on her TikTok account.
The common belief that swallowed chewing gum stays in the stomach for seven years is a myth, according to experts. Swallowing gum is only harmful if done excessively, which is rare. It passes through the stomach and intestines unchanged and is eventually eliminated from the body. While swallowing gum won't cause harm, it has no nutritional value. Gum was historically used by ancient civilizations to stave off thirst and hunger. Swallowing gum is generally not a concern for most people, but it could cause issues for those with gastrointestinal problems or narrowings in the digestive tract.
