Tea and coffee may help protect you from some cancers.







By Dennis Thompson, HealthDay Reporter

THURSDAY, Dec. 26, 2024 -- That morning cup of coffee or afternoon spot of tea might be protecting you from Cancer.

A new evidence review says that coffee and tea consumption is linked to a lower risk of mouth, throat, head, and neck cancers, per the results published in Cancer.

“Even decaffeinated coffee had some positive impact,” senior researcher Yuan-Chin Amy Lee, an epidemiologist with the University of Utah School of Medicine, said in a news release from the journal’s publisher.

Head and neck cancer is the seventh most common Cancer worldwide, with approximately 745,000 new cases and 364,000 deaths in 2020 alone, researchers said in background notes.

For the study, researchers pooled data from 14 prior studies involving more than 9,500 people with head and neck cancer and nearly 16,000 healthy individuals.

They found that people who drank more than four cups of coffee a day, compared with those who don’t drink coffee, had:

  • 17% lower odds of head and neck Cancer

  • 30% lower odds of mouth cancer

  • 22% lower odds of throat cancer

Researchers found that drinking three to four cups of coffee a day was tied to a 41% lower risk of hypopharyngeal Cancer, which occurs at the bottom of the throat. Tea drinking lowered the odds of this Cancer by 29%.

Results show that caffeine didn’t appear to be the only factor in this lowered risk; decaf coffee was associated with a 25% lower risk of mouth cancer.

Previous studies have found that coffee drinking suppresses biological activity that can support Cancer, researchers added.

Researchers found that drinking one cup of tea or less daily lowered the risk of head and neck cancer by 9% overall.

However, more than one cup of tea daily was associated with 38% higher odds of throat cancer, the paper states.

This increased risk might be caused by tea promoting acid reflux in those who imbibe. Reflux has been associated with a higher risk of throat cancer.

“Coffee and tea habits are fairly complex, and these findings support the need for more data and further studies on the impact that coffee and tea can have on reducing cancer risk,” Lee said.

B12 MAY HELP PREVENT ALZHEIMER'S DISEASE.

  B12 MAY HELP PREVENT ALZHEIMER'S DISEASE. Worms don't wiggle when they have Alzheimer's disease. Yet something helped worms with the disease hold onto their wiggle in Professor Jessica Tanis's lab at the University of Delaware. In solving the mystery, Tanis and her team have yielded new clues into the potential impact of diet on Alzheimer's, the dreaded degenerative brain disease afflicting more than 6 million Americans. A few years ago, Tanis and her team began investigating factors affecting the onset and progression of Alzheimer's disease. They were doing genetic research with  C. elegans , a tiny soil-dwelling worm subject of numerous studies. Expression of amyloid-beta, a toxic protein implicated in Alzheimer's disease, paralyzes worms within 36 hours of reaching adulthood. While the worms in one petri dish in Tanis's lab were rendered completely immobile, the worms of the same age in the adjacent petri dish still had their wiggle, documented as ...

EXTREME HEAT MAY NEGATIVELY IMPACT COGNITIVE HEALTH

  EXTREME HEAT MAY NEGATIVELY IMPACT COGNITIVE HEALTH          July 2023 was the hottest month, with cities like Phoenix experiencing record-breaking heat waves for weeks. A new study finds that ongoing extreme heat can worsen cognitive decline among vulnerable groups -- particularly Black older adults and those living in poor neighborhoods. "Our research finds that cumulative exposure to extreme heat can undermine cognitive health, but it does so unequally across the population," said Eunyoung Choi, a postdoctoral associate at the NYU School of Global Public Health and the first author of the study, published in the  Journal of Epidemiology and Community Health . Extreme heat is the leading cause of weather-related deaths in the U.S., claiming more lives each year than hurricanes, tornadoes, and lightning combined. Young children and older adults are particularly vulnerable to heat-related illnesses such as heat exhaustion and heat stroke. Recent stud...

Diabetes drugs may reduce the risk of Alzheimer’s.

    Diabetes drugs may reduce the risk of Alzheimer’s. The study finds people taking the drugs have fewer biomarkers, slower cognitive decline. People taking certain drugs to lower blood sugar for type 2 diabetes had less amyloid in the brain, a biomarker of Alzheimer's disease compared to people with type 2 diabetes who are not taking the drugs and those without diabetes. The new study, published in the August 11, 2021, online issue of  Neurology , the medical journal of the American Academy of Neurology, also found people taking these drugs, called dipeptidyl peptidase-4 inhibitors, showed slower cognitive decline than people in the other two groups. In people with type 2 diabetes, the body no longer efficiently uses insulin to control blood sugar. Dipeptidyl peptidase-4 inhibitors, also known as gliptins, can be prescribed when other diabetes drugs do not work. They help control blood sugar when combined with diet and exercise. "People with diabetes have been shown to ...
