Low vitamin B12 raises risk of dementia in the elderly: Study

According to a latest study the elderly with low levels of vitamin B12 in their blood may be more likely to develop problems with their thinking skills and have more brain shrinkage. The study points to a link between low B12 and early cognitive decline, a condition that often leads to dementia. Previous research has found that those people with high levels of vitamin B12 in their blood have lower levels of an amino acid called homocysteine, which some studies have linked to an increased risk of Alzheimer's disease, memory loss, and stroke.

Taking prenatal vitamins early during pregnancy can reduce risk of having children with autism

Women who reported not taking a daily prenatal vitamin immediately before and during the first month of pregnancy were nearly twice as likely to have a child with an autism spectrum disorder as women who did take the supplements - and the associated risk rose to seven times as great when combined with a high-risk genetic make-up, a study by researchers at the UC Davis MIND Institute has found.

Vegans at increased risk of developing blood clots and atherosclerosis

People who follow a vegan lifestyle - strict vegetarians who try to eat no meat or animal products of any kind - may increase their risk of developing blood clots and atherosclerosis or "hardening of the arteries," which are conditions that can lead to heart attacks and stroke. That's the conclusion of a review of dozens of articles published on the biochemistry of vegetarianism during the past 30 years. The article appears in ACS' bi-weekly Journal of Agricultural and Food Chemistry.

Folic acid supplement does not reduce cardiovascular events, cancer or death

Use of folic acid supplements appears to lower blood levels of the amino acid homocysteine—theorized to be a risk factor for heart and blood vessel disease—but does not appear to be associated with reduced rates of cardiovascular events, cancer or death over a five-year period, according to a meta-analysis of previously published studies in the October 11 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.

'Rotten eggs' gas inside knee joint protects against inflammation

Hydrogen sulfide (H2S) is a gas more commonly associated with the smell of 'rotten eggs' and blocked drains. However, it has now been shown to be present naturally in our bodies and reside in knee joint synovial fluid, the protective fluid found in the cavities of joints that reduces friction between the cartilage of joints during movement. Synovial fluid H2S may play a role in reducing inflammation in joints.
