Long-term beta-carotene may slow mental decline

Men taking beta-carotene supplements for 15 years or more may experience a slower rate of age-related cognitive decline, according to a new study from Harvard.

The study highlights the benefits of long-term nutritional support, noting that no short-term benefits were observed in the 1,904 men taking the supplements for less than ten years.

"In this generally healthy population, the extent of protection conferred by long-term treatment appeared modest; nonetheless, studies have established that very modest differences in cognition, especially verbal memory, predict substantial differences in eventual risk of dementia; thus, the public health impact of long-term beta carotene use could be large," wrote the authors in the Archives of Internal Medicine.

With growing concern over cognitive decline, this news is welcome news.
