They can be sent through the mail, and we're able to extract high-quality, high-quantity DNA."įollow Natalie Wolchover on Twitter nattyover. "Samples can be frozen and thawed multiple times. ![]() "One-half of an eyedropper drop is enough to get a reasonable sample of DNA," Granger said. Your spit contains your entire genetic blueprint, and in a form that may be easier to work with than DNA extracted by other methods. It could also reduce their risk of the autoimmune diseases, such as asthma, that are common in industrialized countries - epidemiology evidence indicates that these ailments result from underexposure to pathogens before age 2.įortunately, spit is also swimming with antibodies that reduce the infectiousness of the bacteria in their midst this means exposing babies to spit gives them a taste of pathogens while usually preventing them from getting sick. ![]() Pre-mastication - the act of pre-chewing adult food and feeding it to one's baby - was standard practice among our blender-lacking ancestors and remains common in many of the world's cultures. Now, it may be coming back in vogue in the West, too, thanks to research indicating a mother's saliva helps boost her infant's immune system.īy exposing infants to traces of disease pathogens present in a mother's spit, pre-mastication gears up their production of antibodies, teaching their immune systems how to deal with those same pathogens later in life. In a study published in February, they identified the way sAA levels naturally change over the course of pregnancy, and the pattern by which they vary throughout the day this lays the groundwork for future research investigating the effect of unusually high stress levels on infants. The Johns Hopkins team has developed a method of gauging the impact of a mother's stress on her unborn baby by monitoring sAA levels in her saliva. The stress or emotional trauma that a pregnant woman experiences can affect the health of her fetus. The salivary glands flood the mouth with an enzyme called salivary alpha-amylase (sAA), and this can serve as a marker of stress. ![]() Stress triggers the body's fight-or-flight response, causing, among other things, a rush of adrenaline, an increased heart rate and salivation. These off-balance levels indicate emotional over-sensitivity to stressful situations, a trait that can negatively affect life choices and stress management. The researchers found that when a girl's father-daughter relationship is characterized by rejection, chaos and coercion, her saliva exhibits lower-than-normal levels of the stress hormone cortisol in the morning, and elevated cortisol levels when she is discussing problems or anxieties with friends. But why? As detailed in a recent paper by Granger and his team, the answer may be swimming in spit. Research shows that daughters who have warm relationships with their fathers begin puberty later, wait longer to start dating and having sex, and are more likely to be monogamous. It could be done on a more regular basis, even in their homes," Granger said in a press release. Once a saliva test is available, "more people would be willing to have the test done. According to the researchers, spit contains the same protein, called C-reactive protein, that indicates a risk of heart disease when found in blood at elevated levels, and spit can therefore give a rough proxy of a patients' heart health. Now, in a new study, Granger and his colleagues have proposed a saliva test to replace the standard blood test. ![]()
