Eating healthier means living longer

22.12.2010
According to new study in the Journal of the American Dietetic Association

The leading causes of death have shifted from infectious diseases to chronic diseases such as cardiovascular disease and cancer. These illnesses may be affected by diet. In a study published in the January 2011 issue of the Journal of the American Dietetic Association, researchers investigated empirical data regarding the associations of dietary patterns with mortality through analysis of the eating patterns of over 2500 adults between the ages of 70 and 79 over a ten-year period. They found that diets favoring certain foods were associated with reduced mortality.

By 2030, an estimated 973 million adults will be aged 65 or older worldwide. The objective of this study was to determine the dietary patterns of a large and diverse group of older adults, and to explore associations of these dietary patterns with survival over a 10-year period. A secondary goal was to evaluate participants' quality of life and nutritional status according to their dietary patterns.

By determining the consumption frequency of 108 different food items, researchers were able to group the participants into six different clusters according to predominant food choices:

"Healthy foods" (374 participants)
"High-fat dairy products" (332)
"Meat, fried foods, and alcohol" (693)
"Breakfast cereal" (386)
"Refined grains" (458)
"Sweets and desserts" (339).
The "Healthy foods" cluster was characterized by relatively higher intake of low-fat dairy products, fruit, whole grains, poultry, fish, and vegetables, and lower consumption of meat, fried foods, sweets, high-calorie drinks, and added fat. The "High fat dairy products" cluster had higher intake of foods such as ice cream, cheese, and 2% and whole milk and yogurt, and lower intake of poultry, low-fat dairy products, rice, and pasta.

The study was unique in that it evaluated participants' quality of life and nutritional status, through detailed biochemical measures, according to their dietary patterns. After controlling for gender, age, race, clinical site, education, physical activity, smoking, and total calorie intake, the "High-fat dairy products" cluster had a 40% higher risk of mortality than the "Healthy foods" cluster. The "Sweets and desserts" cluster had a 37% higher risk. No significant differences in risk of mortality were seen between the "Healthy foods" cluster and the "Breakfast cereal" or "Refined grains" clusters.

According to lead author Amy L. Anderson, Ph.D., Department of Nutrition and Food Science, University of Maryland, the "results of this study suggest that older adults who follow a dietary pattern consistent with current guidelines to consume relatively high amounts of vegetables, fruit, whole grains, low-fat dairy products, poultry and fish, may have a lower risk of mortality. Because a substantial percentage of older adults in this study followed the 'Healthy foods' dietary pattern, adherence to such a diet appears a feasible and realistic recommendation for potentially improved survival and quality of life in the growing older adult population."

The article is "Dietary patterns and survival of older adults" by Amy L Anderson, Ph.D.; Tamara B Harris, M.D., M.S.; Frances A Tylavsky, Dr.P.H.; Sara E Perry, M.A., M.P.H.; Denise K Houston, Ph.D., R.D.; Trisha F Hue, M.P.H.; Elsa S Strotmeyer, Ph.D., M.P.H.; and Nadine R Sahyoun, Ph.D., R.D. It appears in the Journal of the American Dietetic Association, Volume 111, Issue 1 (January 2011) published by Elsevier.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
