BIOL 2320C: Nutritional Science

Week 6: Food Issues

Week 6: Food Issues

Food is like the fuel in your car. If you want your car to run optimally, you will put the appropriate grade of gas in your tank and fill it up regularly. Throughout this course, you have learned that what goes into the body fuels it for healthy living, disease prevention, and optimum function. There are times when even healthy foods can be deemed unsafe due to natural contaminants, poor preservation and preparation, and substandard growing conditions. Strawberries have been recalled due to E. coli contamination. Lettuce has been recalled because of salmonella. Often, these problems can be solved by a recall or by washing the food with soap and water. But, in some cases, a large population gets very sick before the problem receives attention.

This week, you will learn about food safety issues and ways to decrease the risk of food-borne illness. You are nearing the end of your Nutritional Science journey. As you conclude this week’s coursework, be sure to take a moment to consider the effect information in the course has had on your own diet and eating habits.

Learning Objectives

Students will:
  • Analyze risks associated with improper food safety
  • Appraise the effectiveness of policies and regulations designed to protect the food supply
  • Recommend ways to reduce the impact or eliminate a food safety issue
  • Demonstrate knowledge of food safety issues

  • Chapter 12, “Food Safety, Technology, and the New Food Movement” (pp. 368–398)Chapter 12 focuses on food safety, prevention of food-borne illnesses, malnutrition, and food preservation techniques.

The following USDA websites provide online food safety information, updates on food-borne illness outbreaks, guidelines for food preservation, resources for how to handle your food safety, and alerts on food recalls.United States Department of Agriculture: National Agricultural Library: Food Safety Research Information Office.

The FDA branch of the U.S. Department of Health and Human Services also provides several different websites to make sure that food safety information is available to the public.U.S. Food and Drug Administration.

Discussion: Food Safety Issues

The U.S. Food and Drug Administration has strict guidelines for food safety. Bacteria, fungi, pesticides, hormones, and artificial compounds plague food supplies. What makes these contaminants frightening is that they are not generally visible to the naked eye and evidence of their presence in foods can be very difficult to detect without scientific testing. In this Discussion, you will look at how food safety affects health and explore solutions.

To prepare for this Discussion:

  • Review Chapter 12 of the course text, Nutrition for Life.
  • Think about the food contaminants affecting everyday foods.
  • Consider policies and regulations designed to protect the food supply. Are they effective?
  • Choose a food issue that is important to you. It may be an issue presented in your book or another one of your choice. Some suggested topics may include: food-borne illness, food additives and preservatives, pesticides, malnutrition, artificial sweeteners, water quality, et cetera.

With these thoughts in mind:

By Day 3

Post a 2- to 3-paragraph summary outlining the risks associated with a particular food safety issue. Be sure to include the following:

  • Justify why it is a food safety issue.
  • Correlate your food issue to a disease or health concern.
  • Evaluate and suggest 2–3 steps that could reduce the impact or eliminate the food issue.

Be sure to support your ideas by connecting them to the week’s Learning Resources, or something you have read, heard, seen, or experienced. Use at least two APA-formatted references for full credit.

Read a selection of your colleagues’ postings.

By Day 5

Respond to at least two of your colleagues’ postings in one or more of the following ways:

  • At least one response must be on a topic to which you did not initially post.
  • Provide your own interpretation of the food issue and your suggestions as to how to alleviate the problem.
  • Ask a probing question.
  • Share an insight from having read your colleague’s posting.
  • Offer and support an opinion.
  • Validate an idea with your own experience.
  • Make a suggestion.
  • Expand on your colleague’s posting.

Return to this Discussion in a few days to read the responses to your initial posting. Note what you have learned and/or any insights you have gained as a result of the comments your colleagues made.
