But a new study led by Jennifer Orlet Fisher, director of the Family Eating Laboratory at Temple's Center for Obesity Research and Education, has found that adding a small amount of dip to a serving of vegetables helped bitter sensitive children eat more of them.
The study, published on line this month in the Journal of the American Dietetic Association, studied 152 pre-school aged children in the Head Start program who were served broccoli at snack time over a 7-week period, and found that offering 2.5 ounces of ranch dressing as a dip increased broccoli consumption by 80 percent among bitter-sensitive children. Low-fat and regular versions were tested, and both were equally effective.
"We know that children can learn to like vegetables if they are offered frequently, without prodding and prompting," said Fisher. "Children with a sensitivity to bitterness may avoid certain vegetables, but offering a low-fat dip could make it easier for those foods to become an accepted part of children's diet."
She added that parents don't necessarily need to stick to dressings high in fat and salt to see a positive effect. "Try applesauce, hummus, or a low-fat yogurt-based dip for more calcium," she suggested.
Dislike of the bitterness in some foods may stem from the TAS2R38 gene, which influences how we perceive bitter tastes. To determine which children in the study had this sensitivity, researchers offered each child a cup with increasing amounts of a bitter-tasting compound common in green vegetables. After each cup, the child was asked whether the fluid tasted like water, or was "bitter or yucky." About 70 percent of the children responded in the latter.
"Parents and caregivers do not make laboratory measurements of children's bitter sensitivity, but most will know if their child is wary of vegetables," said Fisher. "Our research shows that offering dip is another tool that parents can use to help children learn to eat their vegetables."
Fisher is an unpaid scientific advisor for the International Life Sciences Institute of North America Food, Nutrition and Safety Program. The research was funded by a grant from the Clorox Company, owners of the Hidden Valley, The Original Ranch brand of dip used in this study. Fisher has no financial interest in the company.
Contributing authors on this study are Julie Mennella of the Monell Chemical Senses Center; Sheryl Hughes and Yan Liu, of the Baylor College of Medicine; Patricia Medoza of the University of Texas Medical School at Houston; and Heather Patrick, of the National Cancer Institutes.
Fisher and researchers take full scholarly authority over the research designs, methods, data, analyses and interpretation of the findings within this study.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
