Elderly who eat better stay mentally sharp: study

Published

on

WASHINGTON — Elderly people with higher levels of certain vitamins and omega 3 fatty acids in their blood score better on mental acuity tests than those who eat junk food, a study released Wednesday showed.

The study published in Neurology, the journal of the American Academy of Neurology, also showed that eating better could help reduce the brain shrinkage commonly associated with Alzheimer’s disease.

“This approach clearly shows the biological and neurological activity that’s associated with actual nutrient levels, both good and bad,” said Maret Traber, a principal investigator at the Linus Pauling Institute and study co-author.

Researchers at the institute at Oregon State University conducted the study, one of the first of its kind, along with scientists at the Oregon Health and Science University in Portland.

The study, carried out among 104 people at an average age of 87, specifically measured a wide range of blood nutrient levels instead of basing results on food questionnaires, which are less precise and less reliable.

“The vitamins and nutrients you get from eating a wide range of fruits, vegetables and fish can be measured in blood biomarkers,” Traber said.

“I’m a firm believer these nutrients have strong potential to protect your brain and make it work better.”

Researchers noted the positive effects of high levels of vitamins B, C, D and E, as well as the healthy oils most commonly found in fish, on mental quickness and brain size.

Those with a higher intake of trans-fats — commonly found in fried foods, fast foods and other less healthy diet options — did not perform as well on cognitive tests.

Researchers found that while age and education affected performance on the cognitive tests, nutrient status accounted for 17 percent of the variation in scores, and 37 percent of the differences in brain volume.

Of those who took part in the study, seven percent showed a vitamin B12 deficiency, and 25 percent did not have enough vitamin D in their systems.

Scientists tested 30 different nutrient biomarkers. In addition, 42 participants had MRI scans to measure their brain volume.

“These findings are based on average people eating average American diets,” Traber said.

“If anyone right now is considering a New Year’s resolution to improve their diet, this would certainly give them another reason to eat more fruits and vegetables.”

Study co-author Gene Bowman of the Oregon Health and Science University added while results needed to be confirmed, “it is very exciting to think that people could potentially stop their brains from shrinking and keep them sharp by adjusting their diet.”

Trump lies to the press about his massive tax increasing while departing to France for the G7 Summit

Published

on

President Donald Trump was caught repeating inaccurate claims when he spoke to reporters before boarding Marine One for his trip to France for the G7 Summit.

"I think our tariffs are very good for us. We're taking in tens of billions of dollars, China is paying for it," Trump argued.

In reality, China is not paying for the tariffs, which are paid by American importers and passed on to consumers, making the announcement a massive tax increase on Americans.

"Our tariffs are working out very well for us, people don't understand that yet," Trump argued.

Bill Maher dances on David Koch’s grave: ‘I’m glad he’s dead and I hope the end was painful’

Published

on

HBO "Real Time" host Bill Maher celebrated the death of right-wing billionaire David Koch, who died of prostate cancer.

"I guess I'm going to have to reevaluate my low opinion of prostate cancer," Maher said.

"Condolences poured in from all the politicians he owned and mourners are being asked, in lieu of flowers, to just leave their car engine running," he said.

"I know these seem like harsh words and harsh jokes, and I'm sure I will be condemned for them on Fox News, which will portray Mr. Koch as a principled libertarian who believed in the free market," Maher said. "He and his brother have done more than anybody to fund climate science deniers -- for decades."
