Macronutrients definition
Nutrients needed in large amounts
Micronutrients definition
Nutrients needed in smaller amounts but still important
What are the macronutrients?
Carbs, Proteins, Lipids, Water
What are the micronutrients?
Vitamins and minerals
What is a vitamin
COMPOUNDS essential for normal physiological processes
What is a mineral
ELEMENTS essential for normal physiological processes in the body
What is a calorie?
Energy needed to raise 1 g of water 1 degree C
How are kcals determined
A food is put into a bomb calorimeter and the energy output is determined by the heat
produced
Kcal/g of the nutrients
Carbs: 4
Proteins: 4
Lipids: 9
Vitamins, Minerals, Water: 0
Alcohol: 7 (but not a nutrient)
Phytochemical definition
Compounds found in plants that are believed to provide healthy benefits beyond the
traditional nutrients
Phytochemical found in tomatoes that is thought to decrease cancer risk (esp.
prostate)
Lycopene
Diets rich in _____ and ___ have been shown with a decreased rate in chronic
diseases.
fruits and vegetables
Zoochemicals
,Compounds found in animals that are believed to provide healthy benefits beyond the
traditional nutrients
Compounds that are both phyto and zoochemicals
Lutein and Zeaxanthin - yellow carotenoids found in kale, spinach, and corn. or found in
egg yolk
Functional food defintion
A food, or food ingredient, that may provide a health benefit beyond the traditional
nutrients it contains
Scientific method
3 types of studies
Cross-sectional: Present
Case-control: Past
Prospective cohort: future
Cross-sectional study
Compare different populations at the same point in time
Example of a cross-sectional study
French paradox. Despite consuming same amount of cholesterol/saturated fat france
had 5x lower death rate from coronary heart disease. Led to research into resveratol
(red wine)
Ecologic fallacy
Believing that members of the group have characteristcs, which as individuals they do
not
Case control study
Look at a group of cases vs controls
Retrospective
Often uses food frequency questionnaires
Prospective Cohort study
Initial information on a group collected (food frequency questionnaire) and then group is
followed over time to quantify health outcomes of the individual
Framingham Heart Study
Started in 1948
Following residents to identify risk factors for heart disease
Nurses Health Study
Started in 1976
Every 4 years, 122k nurses are given food frequency questionnaires
Health Professionals Follow up study
Started in 1986
51K male health professionals
Every 4 years, food frequency questionnaires
From the Health Professionals Follow Up study, what was determined
Tomato sauce, tomatoes, pizza, and strawberries had decreased incidence of prostate
cancer
What did the foods have in common from the Health Professionals Follow Up
Study?
Tomato --> Lycopene
Strawberries --> Anthocyanins
,In vitro research
Simplest form of nutrition research
Means "within glass"
Cell culture
In vivo research
Animal study
often mice and Rats
Pros/Cons of in vivo research
Pros
Can do tests that are considered unethical for humans
Knows exactly what subject eats
Expert reporting
Cons
Animal metabolism/physiology is different
Clinical trial
Scientifically controlled study using consenting people to find the safety and
effectiveness of different items/regimens
Gold standard
A p-value of less than ___ is used to indicate statistical significance.
Meaning that...
.05
5% of the time the results are accidental or not true
OR, RR, HR values and signficance
<1 is lowered risk with exposure
1 is no effect
>1 is increased risk with exposure
Confidence interval
Estimated range that the measure is calulated to include
Often 95%
Large VI = Less confidence in value
Small CI = More confidence in value
Must not overlap 1 for OR,RR, or HR to be considered significant

, Systematic Literature Reviews
Clincial trials
Prospective Cohort

Order of research progression
Epidemiological
In vitro
Animal studies
Clinical trials
