Researchers at Monell Chemical Senses Center have figured out that nasal congestion is influenced by more than just nasal airflow. Apparently temperature and humidity influence the perception of nasal congestion just as much as how physically obstructed the nose is.
By having volunteers breath air with variations in temperature and humidity, they have determined that cool and dry air minimizes nasal congestion without any change in how open the nasal cavity is.
By taking into account other measured variables, they have deduced that nasal congestion is influenced by Read more »

Attention, pregnant women! The foods you eat now might influence your babies’ palates after they are born. New research published in the journal Pediatrics, shows that the fetus actually drinks amniotic fluid in the womb. The amniotic fluid is flavored by the foods the mother has recently eaten and flavors can be transmitted to the amniotic fluid and mother’s milk.
It makes sense that as the baby is developing, memories are being created by a sense of taste. Could what a mother eats influence food preferences and odor preferences for life? Researchers fed babies cereal flavored with carrot juice vs. water. They showed that babies who experienced daily carrots in amniotic fluid or mother’s milk ate more carrot-flavored cereal and made less negative faces when eating it.
Julie Mennella studies taste in infants at the Monell Chemical Senses Center (Philadelphia) and she says Read more »

Scientists know that our perceptions about taste and texture drive our food preferences. They know quite a lot about the role of taste in this regard, and the results of some recent experiments have shed new light on the role of texture as well, particularly as it relates to foods containing starch.
Starch is a major component of potatoes, rice, corn, wheat and the enormous variety of foods derived from them. It is also added to many other products from maple syrup to pudding. In fact, starch accounts for 40 to 60 percent of the calorie content in the average Western diet, and more than that in many Asian and third-world diets.
Humans begin digesting starch in the mouth, where the salivary glands secrete an enzyme known as amylase. This enzyme breaks down starch and other complex carbohydrates into simpler sugar molecules which end up being absorbed from the small intestine into the bloodstream. Read more »
