Most diets provide adequate levels of protein, even when trying to achieve protein intakes of 1.2 to 2 grams/kilogram of bodyweight. However, protein supplementation can be utilized in some instances. Discuss instances in which you think protein supplementation would make sense or be warranted?
According to current dietary recommendations, trans fat intake should be limited. How is this best accomplished?
Group of answer choices
Select foods containing manufactured rather than naturally occurring trans fats.
Read labels to select foods that say “polyunsaturated fatty acid free.”
Choose foods with <10% of calories from saturated fat per serving and no hydrogenated oils in the ingredients list.
Use fat replacers, such as olestra, which provide the same nutrient content as regular fats without being saturated.
Avoid all processed foods such as bakery items, packaged cookies, and store-bought bread.
Discuss protein metabolism and the use of proteins as an energy source.

- Fat can be defined loosely as a source for energy storage in the human body. The human anatomy is designed to carry food reserves to ensure the body's survival when food becomes scarce. However, in our slim-conscious society, many people go to great lengths to keep fat from accumulating on their bodies, sometimes with harmful effects. Fat is more efficient in storing energy than carbohydrates for several reasons. First, fat is a highly concentrated energy source. Second, fat weighs less than the same energy amount of carbohydrates. Third, fat is much more efficient to carry as an energy source because it does not hold water as do carbohydrates. For example, an average 70-kilogram human male normally has about 11 kilograms of fat in his body. This fat represents enough stored energy to keep him alive for a month without eating. The same amount of energy stored as starch would double his body weight. Which view does the passage support? A. Fats lead to high levels of cholesterol. B.
