Horror movies, books and fan-fics are always trying to claim that vampires gravitate towards a specific flavor of blood- that they can sense it even before one crimson drop hits their tongue.
Some of it’s milky, some sweet.
Even the fake blood used on set has a specific taste. In a Vanity Fair interview, True Blood’s Kristin Bauer admitted the prop is “really sweet, like sugar water.”
“I turned the bottle around once and read the ingredients,” she said. “It’s corn syrup, red dye, and gelatin. It’s amazing some of the things the special-effects people on True Blood can cook up.”
But the lore associated with vampire’s taste buds might not be too far off from the truth.
Mosquitos are attracted to a certain type of blood also.
Metabolism and body chemistry play a huge roll in the aroma and flavors of your blood.
Yahoo! Health explores some more interesting factors in what distinguishes your blood as a top shelf beverage or a stale leftover dish.
You’re their type
Mosquitoes are nearly twice as likely to land on people with type 0 blood than those with type A, according to a Japanese study. Most people secrete substances that allow mosquitoes to identify blood type before they bite.
Drunk on you
According to a study published in Journal of the American Mosquito Control Association, beer also increases your likeliness of being biten. The researchers reported that, “Mosquito landing on volunteers significantly increased after beer ingestion compared with before ingestion.”
It must be the moon
The tiny bloodsuckers are 500 times more active when the moon is full, reports the American Mosquito Control Association. Overall, the highest risk times for mosquito bites are dusk and dawn, with the females of some species migrating up to 40 miles in pursuit of a meal. Male mosquitoes don’t bite.
Scientist Bart Knols used his own body as a guinea pig to see which parts mosquitos bite most. Sitting in his underwear, he found that 75 percent of the bugs homed in on his feet. But after he washed them with deodorant soap, the mosquitos bit randomly. His team also reported that stinky cheeses, such as Limburger—which has the same odoriferous compound responsible for foot odor—also draws mosquitoes.
Of mosquitos and mothers
Expectant mothers get bitten about twice as often as women who aren’t pregnant, increasing their risk for bug-borne diseases, according to a study conducted in Gambia. The researchers hypothesized that since women in the later stages of pregnancy exhale 21 percent more volume, mosquitos were drawn in by the moisture and carbon dioxide in their breath. They also found that pregnant women’s abdomens are nearly 1 degree warmer, which may cause more volatile substances—released in sweat and attractive to mosquitos—to be present on their skin.
You can run, but you can’t hide
Both the carbon dioxide we exhale and substances in sweat, such as lactic acid, help mosquitoes home in on their prey. As a result, Dr. Koehler reports. “You’re more likely to be bitten if you’re running or exercising than when you’re at rest, since you’re breathing harder and sweating more.” In fact, physical activity ups risk for bites by as much as 50 percent, according to AMCA.
Dark and devious
Many insects, like bees, are attracted to bright colors resembling a flower. Not mosquitos. Dark-colored clothing can increase your risk of being bitten, compared to lighter-colored garments. In one study comparing the appeal of various hues to mosquitoes, the researchers reported the following results: black (most attractive); red (very attractive); grey and blue (neutral); khaki, green, light khaki, and yellow (less attractive).
