Nutrition Science Fair Project

Can We Taste the Difference?

Can We Taste the Difference? | Science Fair Projects | STEM Projects
Are you able to tell the difference between regular and low-fat foods? In this experiment, we'll find out if people can taste the difference between regular and low-fat versions of the same food.


The hypothesis is that people can taste the difference because the ingredients are changed, therefore it alters the taste as well.

Method & Materials

You will test five boys and five girls, all in the same age range, with various fat and low-fat foods. You will measure if they think it is low fat or regular and if an aftertaste was detected.
You will need fat and low-fat versions of Nilla wafers, ice cream, brownies, potato chips, graham crackers, and vanilla pudding from the same manufacturer.


The results showed that people can tell the difference between some fat and low fat foods. This experiment proved the hypothesis to be correct.

Why do this project?

This science project is interesting because it tests people's ability to taste the difference between regular and low-fat foods.

Also Consider

Experiment variations to consider include testing different types of food, or testing people of different ages.
