Description

Most people purchase groceries from their local grocery store or supermarket, which today offers a wide selection of processed, commercial foods and possibly a section of organic or natural foods. To keep a wide selection of fruits and vegetables available to the public, produce is imported from other states or countries and kept as fresh and "presentable" as possible through a variety of commercial methods, such as chemical additives, refrigeration, or early picking. To keep up with the demand for meat and eggs, your protein selections have also been commercialized so that shelves can stay stocked.


Are your food choices contributing to a healthful lifestyle for you and the environment? Does how the food is produced influence your food choices? This week's Application asks you to examine how some foods are produced, and how those choices may or may not impact the health of individuals and of the Earth.

To prepare for this Application:


Review the Organic Trade Association's recommendations on allowable materials for use by organic farmers, organic livestock producers, and organic processors. See this week's Learning Resources for the link.

Consider the impact that chemical fertilizers, often used in produce production, have on human health as well as on the environment.

Reflect on the potential impact of growth hormones or antibiotics used on animals that are a food source for you.

The assignment:


Select one protein item and one produce item from the following table:


Protein


Produce


Chicken

Beef

Lamb

Duck

Eggs

Pork

Fish/Seafood

Tomato

Corn

Lettuce

Spinach

Peas

Carrots

Cabbage

Sprouts

Beans

Broccoli

Strawberries

Bananas

Mango

Cherries

Oranges

Cantaloupe

Watermelon

Pineapple

Apples

Plums

Using sources on the Internet, research the different methods of commercial and natural/organic production for the protein and produce items you selected. Identify the chemicals, processes, and natural resources used to produce these foods and bring them to the market.


Compose a 2-page essay in which you do the following:



Summarize your findings for the commercial and natural/organic production of the protein and produce item you chose to research.


Based on your findings, compare the use of chemical fertilizers and pesticides with the use of natural methods of production. Analyze the impact each of these methods may have on human nutrition, human health, and the environment.


Conclude with a reflection on what changes you might reasonably make when buying food at the store after this research. If you decide not to change anything, what are the driving factors that influenced your decision?
