How food regulates and supports gene function

Chapter 1

During this module of instruction you will be reading Chapter 1 in your textbook titled "The Toxic Western Diet." During this module of instruction you will learn how your diet and environment influences the way your genes behave or express themselves. The study of these "gene-environment interactions" is called epigenetics. The study of how dietary factors influence gene expression is called nutritional epigenetics. Understanding the dietary factors that influence gene expression is key to maintaining good health and preventing disease. In the case of pregnancy, a healthier maternal diet significantly reduces the risk of birth defects and child neurodevelopmental disorders.

Learning Objectives

1. Describe the importance of, and mechanism for, building methylation capacity.

2. Recognize the importance of dietary calcium in carrying out functions of the PON1 and BDNF genes.

3. Recognize the role of dietary zinc in carrying out the function of the MT gene.

4. Describe the gene-environment interactions associated with autism and ADHD.

5. Describe the role of calcium in the elimination of lead from the body and the prevention of ADHD.

Module 1 Activities

1. Read Chapter 1 in your text. Take notes that will help you achieve your learning objectives.

2. Survey your refrigerator, freezer and cupboards for foods listed in the methyl group table at the top of page 4 in your textbook. List the foods high in methyl groups that you found in your kitchen. Do you eat any of these foods daily and at every meal?

3. Click on the link provided and view the video titled, "Ghost in Your Genes."

4. Participate in the zoom meeting discussion. Be sure to answer the discussion questions in advance of the meeting.

Module 1 Discussion Questions

1. What is methylation and how does it work to prevent or promote disease?

2. Describe two genes involved in autism and ADHD and the factors that may influence their activity or the way they function.

3. Based on your kitchen survey(s), what measures can you take to improve your dietary environment?
