Module Four - Ingredients That Add Heavy Metals To Your Body
During this module, you will identify the most common food ingredients that contain heavy metals. Scientists have determined the concentration of heavy metals in food stuffs eaten by humans correlate to the heavy metals found in their bloodstream. We now know that such exposures increase your risk of certain diseases such as Type-2 diabetes. Children with autism and ADHD commonly have higher heavy metal levels in their blood.
1. Recognize the food ingredients that contain allowable heavy metals (e.g. lead, inorganic mercury, cadmium, arsenic).
2. Describe how heavy metals may be introduced to food ingredients (e.g. vegetable oils, corn sweeteners, food colors).
3. Explain how exposure to certain heavy metals may lead to changes in zinc status.
4. Become familiar with recipes for preparing zinc rich meals.
5. Prepare a zinc rich meal.
1. Read Chapter 4 of your Unsafe At Any Meal book.
2. Using the tables provided in Chapter 4, survey your kitchen cupboards and refrigerator to find and list all of the food products that may contain ingredients with at least one heavy metal impurity. You will need to read the food ingredient labels. For example, the food ingredient label below contains two ingredients with allowable or known heavy metal concentrations:
INGREDIENTS: Premium brewed green tea, high fructose corn syrup, honey, citric acid, natural flavors, ginseng extract, vit C.
3. Using the list of foods high in zinc you created during Module 2, do a key word search on the Internet to find a recipe that incorporates three or more foods on your high zinc food list. Shop for the ingredients, follow the recipe, and prepare and eat the meal.
4. Answer the discussion questions and talk about them with your friend or in your group.
1. What evidence is there to suggest that consumption of highly processed food contributres to your heavy metal exposure? Provide a reference to support your response.
2. How does heavy metal exposure impact MT gene function and your body's zinc status? From your survey findings, which food ingredients can you eliminate from your diet to improve your zinc status?
3. Share with your friend or group the recipe you followed to prepare your zinc rich meal. Which ingredients were high in zinc? How did the meal turn out?
