What 2 factors are important for Uncle Leon to understand about the GI scale rankings that may surprise people or that are important to know? (one is a food ranking factor and one is physiological)
The main concern is that, 1) some of the foods low on the scale are high in fats, which slows the absorption of sugar when combined together. Therefore, it may not spike the blood sugar but it is also high in fats. Ice cream is a great example of this. On the flip side, carrots are high on the GI scale and they are a great food! In addition, 2) the ripeness of a food, the cooking method and type of sugar can all effect the scale number. Also, 3) an individual's metabolism can affect how much, and how quickly, a person's blood sugar spikes.

Help Aunt Leona differentiate between LDL and HDL cholesterol. Please explain to her the basic differences and how and why elevated LDL concentrations and how and why lowered HDL concentrations in the blood are a sign of cardiovascular disease risk.
1) Low-density lipoprotein (LDL) also know as "bad" cholesterol makes up most of the human body's cholesterol and negatively effect cardiovascular (CV)health. High-density lipoprotein (HDL) also known as "good" cholesterol, raise the risk of heart disease and stroke. 2) HDLs absorb cholesterol and carries it back to the liver and where unnecessary cholesterol is flushed from the body. 3) LDL raises the risk of a heart attack is because it attaches itself to artery walls, creating plaque build up. This build up eventually blocks the arteries and raises the risk for heart attacks and/or stroke.

For each of the 4 DRI reference values, list, in the order given below, what words the acronym represents and briefly describe, in 1-2 full sentences each, the purpose of each value, and/or what value the reference sets. Also, when describing the RDA and the AI, tell Gabriel where the values for both the RDA and the AI are derived from, and/or what makes them different. 1. RDA (1 pt.) 2. AI (1 pt.) 3. UL (1 pt.) 4. EAR (1 pt.)
1. RDA - Recommended Dietary Allowances - The RDA are values and recommendations that are expected to meet the nutritional needs of 97-98% of people in different life stages and gender groups. These values are are derived from solid experimental evidence and reliable observations. 2. AI - Adequate Intakes - The AI provides the same information as the RDA except the that, when a RDA for a specific nutrient cannot be determined due to insufficient evidence or reliable observation an AI value is determined based on available scientific evidence and educated guesswork. 2. UL - Tolerable Upper Intake Levels - Beyond a certain point, it is unwise to consume large amounts of any nutrient. The DRI committee sets the UL to identify potentially toxic levels of nutrient intake. Intakes of a nutrient below its UL have a low risk of causing illness; with chronic intakes above the UL, risks rise. Consumers who take supplements or consume foods and beverages to which vitamins or minerals have been added, rely heavily on the UL. 3. EAR - Estimated Average Requirements - The EAR establishes the average nutrient requirements for given life stages and gender groups that researchers and nutrition policy makers use in their work. Public health officials may also use them to assess the prevalence of inadequate intakes in populations and make recommendations.

Refined grains are grains and grain products from which the bran, germ, endosperm, and husk of the whole grain are removed, making them low in fiber but enriched in vitamins (required by U.S. regulations).

Discuss at least 2 strong arguments you would use in trying to convince Aunt Leona to consume fish rather than take fish oil supplements.
Taking a fish oil supplements does not guarantee that her chances of having a heart attack or stroke are reduced. Large doses may increase the risk for bleeding, delayed wound healing, and immune suppression. Supplements are not a guarantee that you are taking the correct amount at all times or that the body will absorb them as well as getting the nutrients through food. Fish also contains omega-3 fatty acids and omega-6 fatty acids. The omega-3 family contains EPA and DHA, other acids, which have been linked to regulating heart rate and blood pressure, reducing blood clot formation, reducing blood triglycerides, and reducing inflammation-all factors associated with heart health.

Aunt Leona also does not understand what a trans-fatty acids is and what are their harmful effects are. Please explain to her what a trans-fatty acid actually is and make sure to let her know how they specifically effect the different types of blood cholesterol either negatively or positively.
Trans-fatty acids are fatty acids with unusual shapes and are created during the process known as hydrogenation. This change in chemical structure creates trans unsaturated fatty acids, fats that can be used to store foods both on the shelf and in restaurants to increase their "shelf life". Consuming manufactured trans fats pose a risk to the heart and arteries by raising both blood LDL cholesterol and triglycerides, worsening atherosclerosis and increasing tissue inflammation. High intakes are associated with increased CVD and sudden death.

Describe to Jim Bob the relationship between vegetarian diets and high blood pressure in 2-3 brief sentences.
Vegetarians tend to have lower blood pressure, lower rates of hypertension an are able to maintain healthier body weight than the average person.
