Low vitamin D ‘boosts dementia risk’

elderly-woman-10032444

A 6 year research lead by Dr. David Llewellyn and his team at the University of Exeter Medical School, concluded that low levels of vitamin D in older people are linked to the risk of developing dementia. Vitamin D can be found in foods, such as oily fish, supplements, or exposure to sunlight, however elderly people have less efficient skin and must be supplement in other ways. The team found that in 1,169 subjects with sufficient levels of vitamin D, there is a 1 in 10 chance of developing dementia. In 70 subjects with deficiency, there was a 1 in 5 risk of getting dementia. They cannot say that low vitamin D causes dementia but it is worthwhile to continue studying the connection. What are your thoughts on the association of dementia risk with low vitamin D?

Vitamin supplements may lower exercise endurance

Researchers found no difference in performance between the two groups. However, those who took vitamin C and E seemed to produce less of a specific mitochondrial marker in their muscle cells, which suggests of a decrease endurance. What are your thoughts about this study? What are your typical recommendations to patients looking to enhance their exercise endurance?

Good cholesterol may clog arteries

cholesterol-meter-10069234In a recent study published in Nature Medicine, researchers at the Cleveland Clinic found that high-density lipoprotein (HDL) or “good” cholesterol can become dysfunctional and lose its protective properties. When HDL becomes abnormal, it may enter the bloodstream and clog the arteries. Of the 627 patients in the study, researchers found that those who had higher blood levels of abnormal HDL were at greater risk of heart disease. What are your thoughts about this study?
