true
Consuming 2-3 grams / day of plant sterols and/or stanols can reduce total blood cholesterol and LDL levels. True or False
true
Lower fat diets are less energy dense and thus can help with weight loss and body weight maintenance. True orFalse
true
The "absolute" intake of a nutrient (e.g., fat) is the actual amount (grams) eaten. True or False
true
The "relative" intake of a nutrient is how much (i.e., grams) is eaten compared to something else (e.g., total calories). True or False
true
body fat stores are used for energy when all of the energy yielding nutrients from the last meal have been absorbed or when energy expenditures increase
true
dietary fat is more efficiently stored as body fat than dietary carbs
true
fat providers more calories than carbohydrates and is less bulky, both of which explain why eating a high fat is diet can make it easier to overeat calories
true
trans fat increase CVD risk as much or more than saturated fats
true
trans fatty acids are unsaturated fatty acid
true

whole milk
All of the following are reasons why a fat free diet is not recommended except fat in foods contain aromas and flavors we enjoy without fat from foods, most people would not be able to make enough body fat to survive fat helps the diet be more satisfying some fatty acids are essential dietary fat helps in the absorption of fat-soluble nutrients
without fat from foods, most people would not be able to make enough body fat to survive
Which of the following is TRUE about how trans fatty acids increase CVD risk? Check ALL that apply. Diets high in trans fats increase blood LDL and triglyceride levels. Trans fats that are incorporated into LDL particles make the LDLs stick more easily to the artery walls. Trans fats tend to decrease HDLs. Trans fats promote inflammation.

Which of the following statements is FALSE? Fat replacers can be made from carbohydrate or protein or fat. Some fat replacers contribute calories to foods. Some reduced fat foods can be less healthful than the original full-fat food. Fat-free foods are calorie-free. Olestra, a fat replacer made from fatty acids, provides zero calories to the body.
Fat-free foods are calorie-free.
Which of the following FALSE about blood lipid panel? A lipid panel measures the level of total cholesterol, total triglycerides, HDLs, and LDLs in the blood. We must be fasted when our blood is drawn so that the measures reflect how the liver manages body lipid levels day-in and day-out. High levels of all 4 measures in the lipid panel indicated we are at a greater risk for CVD
High levels of all 4 measures in the lipid panel indicated we are at a greater risk for CVD
Which of the following is TRUE about the development of atherosclerosis? Check ALL that apply. Lipid build-up in the arteries starts with injury to the lining of the arteries. The inflammatory cells of the immune system come in to repair the injury. LDL particles get taken up by the immune cells and deposited in the lining of the arteries. Atherosclerosis can significantly narrow the opening through which blood can flow. Blood clots can form that are big enough to get caught in narrowed arteries and block of blood flow. When blood flow is blocked to the heart, this results in a heart attack. When blood flow to the brain is blocked, this is a stroke.

Which of the following statements is TRUE. Because many hormones and other important biomolecules are made from cholesterol there is an RDA for cholesterol. A high intake of good dietary cholesterol, HDL, reduces the risk of cardiovascular disease. Processed foods can be high in cholesterol if they contain hydrogenated oils. Cholesterol is not an essential nutrient because it can be synthesized in the liver.
Processed foods can be high in cholesterol if they contain hydrogenated oils.
The definition of a functional food is a nutrient-dense food. a food modified to contain a substance or nutrient (naturally occurring or added) that confers health benefits beyond that of the traditional food. a new food that serves many different functions in the diet. These statements are all part of the definition of 'functional food'.
