Carotenoid Nutrients Proven to Keep Senior Citizens Active

(NaturalNews) Senior citizens who consume a high dietary intake of carotenoids, nutrients found in colored fruits and vegetables such as carrots, peppers, mangoes and kiwi fruit, are able to walk 'longer and stronger' than those with a low dietary intake, suggest the results of a new study published by the Journal of Nutrition, Health and Ageing.

Researchers at Johns Hopkins Medical Center used blood tests to measure levels of carotenoids in 687 older adults aged sixty-five and over, and subsequently assessed the results against the physical walking performance of the trial participants.

Results showed that a higher dietary intake of fruits and vegetables, as indicated by a higher blood carotenoid level, was associated with a significant protective effect against physical degeneration over the course of three years, as measured by a strong or weak walking performance. [1]

The latest findings are the second such study to examine the connection between these dietary factors and sustainable physical performance in aging. Previous research, also carried out by Johns Hopkins and forming part of the larger Women's Health and Aging Study, revealed that "low serum carotenoid levels, an indicator of low intake of fruits and vegetables, are independent predictors of the progression towards severe walking disability among older women living in the community." [2]

Prior to both studies, the link between a low carotenoid intake and poor muscle strength had been established [3], as had a more general correlation between fruit and vegetable consumption and functional disability in senior citizens. [4]

Researchers in the current study felt that their results may be particularly important given that such mobility assessments can be accurate predictors of future disability and even mortality, and that the findings could help senior citizens in maintaining...
