Milk, fruits and vegetables may help reduce disability risk

07.02.2005


There may be more reason than ever to drink your milk and eat your fruits and vegetables. A Wake Forest University Baptist Medical Center researcher and colleagues reported today that high consumption of dairy products and fruits and vegetables may lower the risk of disability, especially among black women.



The research, in the American Journal of Clinical Nutrition, found that black women who consumed the highest amounts of dairy products and fruits and vegetables – close to the amounts recommended by the 2005 Dietary Guidelines for Americans – had at least a 30 percent lower risk of disability than participants who consumed the lowest amounts of these foods.

And, among all participants, eating more of these foods was associated with lower risk for functional limitations, such as being unable to walk a quarter of a mile or climb 10 steps, that often precede disability. "In general, there was an association between dairy, fruit and vegetable intake and functional limitations and disability," said Denise Houston, Ph.D., a research associate at Wake Forest Baptist. "Getting the recommended number of servings of dairy, fruits and vegetables should be investigated for its potential to reduce the prevalence of disability in the aging population."


Houston, who completed the study while she was a graduate student at the University of North Carolina at Chapel Hill, said the findings are important because the number of disabled elderly is expected to triple between 1985 and 2050. About half of people over age 65 will become disabled enough to require some nursing home care. "We know that obesity, lack of physical exercise, alcohol consumption and smoking are modifiable risk factors for disability, but little is known about the role of diet," said Houston, a registered dietitian.

The researchers believe this is the first study to report on an association between disability and eating certain foods. For the project, they evaluated data from the Atherosclerosis Risk in Communities (ARIC) study, which included about 16,000 randomly selected participants in Forsyth County, Jackson, Miss., Hagerstown, Md., and suburban Minneapolis, Minn. People who had chronic disease and were likely to already be disabled were excluded. Participants, who were between 45 and 64 years old when the study began, were asked to report on their diets over the past year using a 66-item food frequency questionnaire.

Then, an average of nine years later, the researchers surveyed participants on their ability to perform 12 daily activities, such dressing and feeding themselves and walking across a room, known as activities of daily living; being able to cook and manage their money, known as instrumental activities of daily living; and being able to walk a quarter of mile and walk up 10 steps without resting, to measure functional limitations.

The study adjusted for other factors that could have affected the results – such as age, education, smoking, and body mass index – and found that higher amounts of dairy, fruits and vegetables were associated with lower risk of functional limitations. And, among black women, risk of disability was significantly lower.

The median servings for study participants consuming the highest amounts of the foods were two servings of dairy, three servings of fruits and three servings of vegetables. In contrast, median servings for participants consuming the lowest amounts of the foods were less than half a serving of dairy and one or less serving of fruits and vegetables. Current dietary recommendations call for three cups a day of low-fat or fat-free dairy products, two cups (four servings) of fruit and two and a half cups (five servings) of vegetables.

Houston said there are several ways that the foods could affect disability risk. The calcium and vitamin D in dairy foods may decrease the risk of disability associated with osteoporosis and decreased muscle strength. The antioxidants found in fruits and vegetables may reduce the accumulation of oxidative damage in tissues, which could slow disability associated with aging and decrease the risk of chronic diseases that can lead to disability.

Houston’s co-researchers were June Stevens, Ph.D., Jianwen Cai, Ph.D., and Pamela Haines, Ph.D., all with the University of North Carolina at Chapel-Hill.

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
