The risk of autism is not increased by 'too many vaccines too soon'

Posted: 29 Mar 2013 09:46 AM PDT

Although scientific evidence suggests that vaccines do not cause autism, approximately one-third of parents continue to express concern that they do; nearly 1 in 10 parents refuse or delay vaccinations because they believe it is safer than following the Centers for Disease Control and Prevention's (CDC) schedule. A primary concern is the number of vaccines administered, both on a single day and cumulatively over the first 2 years of life.

Monosaturated fats reduce metabolic syndrome risk

Canola oil and high-oleic canola oils can lower abdominal fat when used in place of other selected oil blends, according to a team of American and Canadian researchers. The researchers also found that consuming certain vegetable oils may be a simple way of reducing the risk of metabolic syndrome, which affects about one in three U.S. adults and one in five Canadian adults.

Liquid smoke, black and green teas and coffee produced levels of cell DNA damage comparable to chemo drugs

In a laboratory study pairing food chemistry and cancer biology, scientists at the Johns Hopkins Kimmel Cancer Center tested the potentially harmful effect of foods and flavorings on the DNA of cells. They found that liquid smoke flavoring, black and green teas and coffee activated the highest levels of a well-known cancer-linked gene called p53.

The p53 gene becomes activated when DNA is damaged. Its gene product makes repair proteins that mend DNA. The higher the level of DNA damage, the more p53 becomes activated.

Study Finds Heat Key Factor In Population Growth Of Some Urban Insect Pests

New research from North Carolina State University finds that higher temperatures found in urban environments are a key contributor to higher populations of insect pests called scale insects – indicating that an increase in temperatures associated with global climate change could lead to a significant increase in scale insect populations.
