- Cholesterol is essential for many body processes. Cholesterol produces hormones and bile acids. It is found in animal tissues, but is never present in plants.
- The body has High Density Lipoprotein-(HDL) cholesterol and Low Density Lipoprotein-(LDL).
- HDL cholesterol is considered "good" cholesterol because it transports excess cholesterol found in the blood stream back to the liver. LDL's take cholesterol from the liver to wherever it is needed in the body. LDL cholesterol is considered "bad" cholesterol because if too much LDL cholesterol is circulating in the blood stream, it can build up in the arties and increase the chance of heart disease or stroke.
- High levels of LDL cholesterol is one factor related to heart disease and obesity.
Identify the differences between saturated, monounsaturated, polyunsaturated fats and trans-fatty acids. Discuss the effect of each type of fat on HDL and LDL levels.

- Macro minerals are needed in great quantities in the body.
- Calcium deficiency causes osteoporosis which causes bones to gradually lose their minerals. This causes bones to become weak and frail. Dairy products are good sources of calcium.
Identify sources, functions and effects of deficiency of the trace mineral iron, including the role of iron in preventing anemia. Describe how to identify amounts of iron in foods using food labels.
- Trace / micro minerals are needed in smaller quantities, but are just as essential as macro minerals. Iron deficiency causes anemia, or low red blood cell formation. Animal products provide excellent sources of iron.
Identify sources, functions and deficiencies of the electrolytes sodium and potassium, including their role in fluid balance. Describe how to identify amounts of sodium and potassium in foods using food labels.
- Electrolytes help maintain the fluid balance in the body, help maintain the heartbeat and help muscle and nerve action.
- Electrolytes easily become imbalanced in cases of dehydration, illness and diarrhea.
- Electrolytes like potassium can be found in bananas and potatoes.
- So much sodium is available in the food supply that it is more of a concern to have too much. Label reading is a good way to identify which foods have high amounts.
- If an athlete is trying to replace sodium, then it is advisable to do so with some saltier foods. Foods such as bread and milk contain some sodium.

- Processing (monitor at critical control points)
- Transportation (use clean vehicles and maintain the cold chain)
- Retail (follow the food code guidelines)
- Table (always follow the four C's of safety- clean, cook, control cross contamination, chill).
Discuss how to prevent oxidation of fresh fruits.
- When most fresh fruit is cut, the surface will turn brown. This is called oxidation and is caused by an enzyme in the fruit.
- Prevent oxidation of fresh fruits by dipping or covering fruit with liquid containing ascorbic acid. Another way to prevent oxidation is to wait to cut the fruit until ready to eat.
