Welcome to the fascinating world of nutrition! Nutrition is our favorite area of science because it is so relevantwe all eat and drink several times a day, and the choices we make can have a dramatic influence on health. The science of nutrition, however, can seem a bit confusing. Good nutrition is a moving target; different authorities have different ideas of how we should eat, and nutrition recommendations are subject to change! Also, there are so many choices. The average supermarket carries over 40,000 food and beverage products, and often, The most aggressively marketed items are not the healthiest. Furthermore, as a nation, we eat many of our meals and snacks away from home. When we eat foods that someone else has prepared for us, we surrender control over what is in our food, where the food came from, and how much of it goes on our plates. Undoubtedly, you are interested in what you should be eating and how the food you eat affects you.

Wardlaws Contemporary Nutrition: A Functional Approach is designed to accurately convey changing and seemingly conflicting messages to all students. Our students commonly have misconceptions about nutrition, and many have a limited background in biology or chemistry. We teach complex scientific concepts at a level that will enable you to apply the material to your own life.

The sixth edition of Wardlaws Contemporary Nutrition: A Functional Approach has been written to help you make informed choices about the food you eat. We have emphasized choosing whole, minimally processed foods and hope you enjoy our newest feature, Farm to Fork, which gives you practical advice for incorporating fruits and vegetables into your dietary pattern, from the ground up! We will take you through explanations of the nutrients in food and their relationship to health and will also make you aware of the multitude of other factors that drive food choices. To guide you, we refer to evidence-based research and resources throughout the book. With this information at your fingertips, you will be well equipped to make your own informed choices about what and how much to eat. There is much to learn, so lets get started!
