Which statements about absorption of vitamins or minerals are true? Select all that apply. U Micronutrients may be in competition for absorption with each other. Vitamins and minerals are efficiently absorbed by the body between 85% and 99% of what is consumed. To be useful for cellular function, vitamins must remain in their original chemical structure. Calcium found in plant sources is more readily absorbed than from animal sources. Absorption of some vitamins and minerals can be influenced by what sort of foods are consumed within the same meal.

Which of the following statements regarding dietary nutrients is FALSE? Macronutrients provide cells with energy whereas micronutrients provide protein cofactors. Water soluble vitamins can be stored long-term. Enriched foods contain synthetic vitamins to replace natural vitamins lost during processing. Fortified foods contain vitamins and minerals not originally found in the foods. The majority of B vitamins must be converted to their active form in the body.
Nutrients represent a broad group of substances required for proper body function. Identify the following in the context of human nutrition as essential nutrients, vitamins and minerals Nutrients the body can’t produce and must be consumed in food. Organic molecules required in small quantities. Inorganic molecules required in small quantities.

Nutrition plays a vital role in a person's overall health and well-being. Not getting enough of the recommended nutrients over the long term can lead to malnutrition which often results in disease and illness. In a 3-page paper, written in APA format using proper spelling/grammar, address the following: Define malnutrition and identify a specific disease that can result from it. Perform library research about the selected disease and explain its physiological effects on a person's body. Describe the relationship between specific foods/nutrients and the disease. Use the questions below to guide your response. a) Does research indicate that a lack of specific foods/nutrients increase a person's chance of contracting the disease? b) Are there specific foods/nutrients that should be avoided by an individual afflicted with the disease? c) How do specific foods/nutrients work physiologically within the body to help combat the disease? Evaluate nutritional recommendations to help…
The model that the type of foods one eats is the primary determinant of body mass is best summarized as the micronutrients and especially phytonutrients are the most important contributor to body mass effects of foods macronutrient content is the primary determinant of body mass effects of foods O calorie sources are not identical; and apple is not equal to a can of soda even if they have the same caloric content O any type of food can be understood by knowing the calories it contains
State and recognize the three basic nutritional needs an organism’s diet must satisfy. List the basic stages of nutrition. Predict how perturbations in the hormones leptin and ghrelin influence appetite. Use the concept of pressure to describe the movement of water and nutrients in plant xylem and phloem and blood in vertebrates. Trace the flow of a drop of blood through the four chambers of the heart, the great vessels, lungs, and the blood vessels (arteries, veins, and capillaries) in the systemic circulation in healthy people and people with various malformations of the heart or great vessels. Distinguish between systolic and diastolic blood pressure. Predict how perturbations in body posture or baroreceptors would affect homeostatic control of blood pressure.
