Opting for olive oil could boost brain health

Regular olive oil consumption associated with 28% lower risk of fatal dementia

Opting for olive oil could boost brain health
2023-07-24
(Press-News.org) A new study suggests that incorporating olive oil into your diet could help reduce the risk of dying from dementia. As many countries face rising rates of Alzheimer’s disease and other forms of dementia, the study offers hope that healthy lifestyle factors such as diet can help to prevent or slow the progression of these devastating conditions.

 

“Our study reinforces dietary guidelines recommending vegetable oils such as olive oil and suggests that these recommendations not only support heart health but potentially brain health, as well,” said Anne-Julie Tessier, RD, PhD, a postdoctoral fellow at the Harvard T.H. Chan School of Public Health. “Opting for olive oil, a natural product, instead of fats such as margarine and commercial mayonnaise is a safe choice and may reduce the risk of fatal dementia.”

 

Tessier will present the findings at NUTRITION 2023, the flagship annual meeting of the American Society for Nutrition held July 22–25 in Boston.

 

Dementia includes a range of conditions in which impairments in thinking or memory affect a person’s daily activities. Alzheimer’s, a progressive and fatal disease affecting an estimated 5.7 million Americans, is the most common form of dementia.

 

The study is the first to investigate the relationship between diet and dementia-related death. Scientists analyzed dietary questionnaires and death records collected from more than 90,000 Americans over three decades, during which 4,749 study participants died from dementia.

 

The results indicated that people who consumed more than half a tablespoon of olive oil per day had a 28% lower risk of dying from dementia compared with those who never or rarely consumed olive oil. In addition, replacing just one teaspoon of margarine and mayonnaise with the equivalent amount of olive oil per day was associated with an 8-14% lower risk of dying from dementia.

 

Research suggests that people who regularly use olive oil instead of processed or animal fats tend to have healthier diets overall. However, Tessier noted that the relationship between olive oil and dementia mortality risk in this study was independent of overall diet quality. This may suggest that olive oil has properties that are uniquely beneficial for brain health.

 

“Some antioxidant compounds in olive oil can cross the blood-brain barrier, potentially having a direct effect on the brain,” said Tessier. “It is also possible that olive oil has an indirect effect on brain health by benefiting cardiovascular health.”

 

Previous studies have linked higher olive oil intake with a lower risk of heart disease. Incorporating olive oil as part of a Mediterranean dietary pattern has also been shown to help protect against cognitive decline.

 

Tessier cautioned that the research is observational and does not prove that olive oil is the cause of the reduced risk of fatal dementia. Additional studies such as randomized controlled trials would be needed to confirm the effects and determine the optimal quantity of olive oil to consume in order to reap these benefits. Overall, however, the study aligns with dietary recommendations and bolsters the evidence that using olive oil in place of margarine or mayonnaise can help to support a healthy diet.

 

Tessier will present this research at 8:13 a.m. EDT on Monday, July 24, during the Nutrition-related Factors in Aging and Chronic Disease Poster Theater Flash Session in the Sheraton Boston, Fairfax (abstract; presentation details).

 

Please note that abstracts presented at NUTRITION 2023 were evaluated and selected by a committee of experts but have not generally undergone the same peer review process required for publication in a scientific journal. As such, the findings presented should be considered preliminary until a peer-reviewed publication is available.

Upping your intake of omega-3s may help protect your hearing

2023-07-24
Researchers report that blood levels of the omega-3 fatty acid docosahexaenoic acid (DHA) were inversely correlated with hearing difficulty in a new population-based cross-sectional study. Middle-aged and older adults with higher DHA levels were 8-20% less likely to report age-related hearing issues than those with lower DHA levels.   “Higher DHA levels have previously been found to be associated with a lower risk of heart disease, cognitive impairment, and death. Our study extends these findings to suggest a role for DHA in maintaining ...

What is the best dieting strategy for people with type 2 diabetes?

2023-07-24
Losing weight is often a goal for people with type 2 diabetes, which is strongly associated with being overweight or obese. However, it hasn’t been clear what dieting strategy works best for people with this metabolic disorder.   A new randomized controlled study of people with type 2 diabetes showed that study participants who restricted eating to between noon and 8 p.m. daily lost more weight than those who reduced their overall calorie intake by counting calories. Both dieting strategies produced similar improvements in blood sugar levels.   “Many people find counting calories very hard to stick to in the long term, ...

Wormlike animals are first amphibians shown to pass microbes to their offspring

Wormlike animals are first amphibians shown to pass microbes to their offspring
2023-07-24
Caecilians are an elusive type of amphibian that primarily live underground and look like a cross between a worm and a snake. One of the few things that is known about caecilians is their unique method for feeding their young. Mothers produce a special layer of fatty skin tissue, which juvenile caecilians tear off with baby teeth that evolved specifically for that purpose. A new study shows that skin-feeding does more than provide nutrients for young caecilians. It also helps the mother pass microbes from her skin and gut down to her young, inoculating them to jump-start a healthy ...

Image-guided adaptive radiation treatments reduce short-term side effects for patients with prostate cancer

2023-07-24
A technique that uses imaging technology as a guide can make radiation therapy safer for patients with prostate cancer by helping clinicians accurately aim radiation beams at the prostate while avoiding nearby tissue in the bladder, urethra, and rectum. That is the finding of a thorough analysis of all published clinical trials of the technique, called magnetic resonance–guided daily adaptive stereotactic body radiotherapy (MRg-A-SBRT). The analysis is published by Wiley online in CANCER, a peer-reviewed journal of the American Cancer Society. By providing detailed images, MRg-A-SBRT can be used to adjust a patient’s radiation plan every ...

Children and adolescents in food-insecure homes had more mental health visits

2023-07-24
Children and adolescents living in food-insecure households had a 55% higher frequency of physician visits for mental health reasons than those with adequate food supplies, according to new research published in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.230332. In 2021, almost 6 million people Canada, including 1.4 million children and adolescents younger than 18 years faced food insecurity; that is, inadequate food intake because of financial problems. The study looked at population health survey data from the Canadian Community Health Survey on ...

Gene conferring novel function to seahorse brood pouch identified

Gene conferring novel function to seahorse brood pouch identified
2023-07-24
Teleost fish encompass a diverse group, among which seahorses display a unique morphology. The characteristic spines and brood pouch seen in seahorses feature distinctive epithelial cells—called flame cone cells—covered by a mucous cap. However, these cells are not found in the barbed pipefish Urocampus nanus or the seaweed pipefish Syngnathus schlegeli, close relatives of the seahorse, belonging to the Syngnathidae lineage. While research has hypothesized the function of the flame cone cells, their evolutionary origins have remained a mystery. Now, a team of scientists led by Assoc. Prof. Mari Kawaguchi and Prof. Shigeki Yasumasu from the Department of Materials ...

Two in three cosmetic surgery injections in the UK are not administered by doctors

2023-07-24
According to an analysis of the UK’s cosmetic injectables industry by UCL researchers, 68% of cosmetic practitioners who are administering injections such as Botox are not qualified medical doctors. The study, published in the Journal of Plastic, Reconstructive & Aesthetic Surgery, is the first survey of who is providing cosmetic injectable services, such as Botulinum Toxin (Botox) and Dermal Fillers, in the UK. Currently, little is known about the background qualifications, training and experience levels of those who are administering treatments. To fill this ...

A whole new dimension for 3D printing

A whole new dimension for 3D printing
2023-07-24
3D printing of complex objects typically takes a long time due to the printing process necessarily laying down a large number of 2D layers to build up the object. The process usually wastes a lot of material required to support the unfinished object. Some novel ways to make flat materials self-fold into 3D shapes exist, but have shortcomings. For the first time, researchers combined 2D printing, origami, and chemistry to create a method of rapid 3D object fabrication without creating any waste material. These shapes self-fold in seconds. For some time, 3D printing has been used to prototype ...

A diet originally designed to help ward off cognitive decline in adults might also help improve attention in pre-adolescents, according to a new study. The findings could help inform future dietary interventions aimed at improving cognition in children.   The new study examined two diets: the Healthy Eating Index – 2015 (HEI-2015), which is based on the Dietary Guidelines for Americans, and the Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet, which combines the Mediterranean diet with the heart-healthy Dietary Approaches to Stop Hypertension ...
