*fats cushion organs and insulate
*proteins provide growth and maintance of muscle,tissue, and organs, making
hormones, enzymes, and antibodies,and transporting other nutrients
macronutrients - ANSWERScarbs,fats, and proteins
micronutrients - ANSWERSvitamins and minerals
Describe phytochemicals and their food sources. - ANSWERSnon-nutrient compounds
that contribute to health and may play a role in fighting chronic diseases, they help
prevent lycopene and prostate cancer, and they are found in plants

fat. - ANSWERScarbs and protein= 4kcal/g
alcohol=7kcal/g
fats=9kcal/g
Understand the important roles that vitamins, minerals, and water
play in your diet. - ANSWERSminerals and vitamins are essential for metabolism and

*helps chemical reactions
*transports nutrients and oxygen
*helps maintain body temp
lubricants for joints, eyes, mouth, intestinal tracts
, *protective cushion for organs
Understand the scientific method that is involved in nutrition research. -
ANSWERSScientific method: process used by scientists to generate sound research
findings
Step 1: observe, ask questions, and formulate a hypothesis (idea based on observation)
Step 2: conduct an experiment to test the hypothesis
Step 3: share findings in a peer-reviewed journal (research publication for scientists)
observational research - ANSWERSinvolves looking at two factors in two or more
groups
experimental research - ANSWERSinvolves at least two groups of subject
*experimental group: given a specific treatment
* control group: given a placebo "sugar pill"
*doubled-blind placebo controlled experiments is " gold standard" (neither scientist or
subject know which group gets treatment
who to trust - ANSWERSNutrition experts
*registered dietitian (RD)
*public health nutritionist
* Licensed Dietitian (LD)
