Class Correlation

Strong PTC Taste Everyone that can distinctly taste the

PTC either likes or thinks broccoli is ok 10 people either like or think cabbage is

ok whereas 4 people dislike it Only 6 people like or think Brussels

sprouts are okay and 8 people dislike them

Slight PTC Taste 5 people that can slightly taste the PTC

like or think broccoli is ok and 4 people dislike it

Only 3 people like or think cabbage and Brussels sprouts are ok and 6 people that can only slightly taste the PTC dislike them

No PTC Taste Only 3 people that cannot taste the PTC like

broccoli, 4 people think it is OK, and 2 people dislike it

No one that cannot taste the PTC likes cabbage or Brussels sprouts

4 people think cabbage is OK 3 people think Brussels sprouts are OK 5 people dislike cabbage 6 people dislike Brussels sprouts

Real World Conclusions

The American Society for Pharmacology and Experimental TherapeuticsStudies confirmed earlier reports

that genetically mediated sensitivity to the bitter taste of PTC was associated with lowered acceptability of Brussels sprouts, cabbage, spinach, and broccoli.

Real World Experiment 65 preschoolers 3.5-4.5 years old at the

start of the study 33 girls 32 boys**Children with allergies, recent illnesses, or taking medication that alter food taste were excluded.

Initial findings: 63% were “tasters” 37% were “non-tasters” Vegetable choices:

Raw broccoli*Cucumber*Pitted ripe black olives *Mini carrotsRed bell peppers

*bitter tasting vegetablesPrecision Nutrition Inc. "Research Review: Bitter Blind? Why You Don't Like Broccoli...

Real World Experiment cont.

What did they find? “Non-tasters” eat more vegetables during snack-time

than “tasters” 92% of “non-tasters” ate some vegetables, compared

to only 68% of “tasters” 32% of “tasters” ate no vegetables at all “Non-tasters” ate more bitter vegetables compared to

“tasters”, but there was no difference in broccoli consumption
