Unit 1 – Food Safety

1.1 Introduction

Food and Nutrition Go Hand in Hand

A study of nutrition is incomplete without  discussing food — the two go hand in hand.  Food is the delivery vehicle of nutrients to our bodies.   We need nutrients for growth and repair of our body tissues,  as a source of energy, and to  stay healthy.  And foods need the various  nutrients for their color, flavor, texture, and even shape.

For example, it’s well known that milk is an excellent source of calcium and protein, both are needed to build strong bones.  When we look at a glass of milk,  the white color results from light refracting  and scattering on the milk’s calcium and  proteins.

The sweet flavors of grapes, melons, and oranges are related to the fructose, also known as fruit sugar. And that sweetness quenches our craving for sugary foods, and may prevent us from grabbing a candy bar or frosted cup cake.

And everyone knows that eating  carrots  provides us with the  vitamin A needed for vision.   That vitamin A is  beta-carotene,  the bright orange  pigment that gives  carrots their vibrant color. (And eating too many can make our skin turn orange!)

Adding eggs to pancakes provides a high quality protein that is  needed to help maintain our muscles. That muscle-building  protein in eggs adds moisture, color, and structure to the finished pancakes.

We begin our exploration of this food/nutrition duo in the kitchen. We hope that you will try preparing many of the nutrient packed foods discussed throughout the book  without catching the kitchen on fire or cutting off a finger.  Therefore,   we  begin this unit with  safe practices in the kitchen, followed by how to make sure that our foods are safe to consume and not plagued with contaminants.
