1
how does the government try to guide the population towards a healthy diet
through publication of “nutritional guidelines” and “dietary recommendations”
2
what are nutritional guidelines largely based upon
-avoidance of deficiency symptoms
-lowered risk of chronic diseases especially cardiovascular disease
3
type of study: compare “nutrition” (intake, status) and health outcome in a population or between populations
Ecological and cross-sectional studies
4
type of study: takes “nutrition” measures and then follows the subjects over time
prospective study
5
type of study: compares “nutrition” in cases vs. controls
case control study
6
type of study: testing a hypothesis by modifying “nutrition” – randomised controlled trial
intervention study
7
type of study: a statistical analysis that combines data from separate but similar studies
meta analysis
8
what are the hierarchy of evidence
-properly randomized, controlled trial (best
-Well-designed controlled trial without randomization
-Well-designed cohort or case-control analytic study
-Multiple time series with or without intervention
-Opinions of respected authorities; descriptive studies or case reports; reports of expert committees
9
what is the problem with the first three "best" hierarchy evidence
they can be problematic for nutrition studies
10
in the diet pyramid, what should we have the least amount of servings of and the most of?
least: fat, oils, and sweets
most: bread, cereal, rice, and pasta group (6-11 servings)
11
current problems with the US diet
we eat more solid fats, sugar, sodium and refined grains and less vegetables, fruits, whole grains, milk, oils and fish
12
what is the heavy toll of diet related chronic diseases
there is a high percentage of people with CVD, diabetes, hypertension, cancer, and osteoporosis
all of which could be avoided with better health
13
define nutrient dense foods and beverages
-Provide vitamins, minerals, and other beneficial substances and relatively few calories without
• Solid fats in the food or added to it
• Added sugars
• Added refined starches
• Added sodium
-Retain naturally occurring components, such as dietary fiber
14
what foods are considered nutrient dense
All vegetables, fruits, whole grains, seafood, eggs, beans and peas, unsalted nuts and seeds, fat-free and low-fat dairy, and lean meats and poultry are nutrient dense when prepared without solid fats or sugars
15
proportion of disease prevalence attributed to obesity in USA -- in descending order
Type 2 diabetes
uterine cancer
gall bladder disease
osteoarthritis
hypertension and coronary heart disease
breast and colon cancer
16
is there evidence that a low carb/high protein or low fat diets are better for you than a normal diet?
no
17
what types of diet have been shown to work
"low energy density" diets which means lower calories but plenty of micronutrients (aka plenty of fruits and veggies)
18
what are important modifiable factors that can help manage weight
-calories consumed in foods and beverages
-calories expended doing physical activity
so CALORIE BALANCE OVER TIME IS KEY!!!
19
for kids less than 2, children and adolescents, and adults -- where do the highest sources of calories come from?
kids less than 2: grain based desserts and yeast bread
children and adolescent: grain based desserts and pizza
adults: grain based desserts and yeast bread
20
physical activity recommendation for 6-17 years old
60 minutes or more of moderate of vigorous physical activity a day
21
physical activity recommendation for 18-64 years old
150 minutes a week of moderate intensity activity or 75 minutes a week of vigorous intensity activity
22
physical activity recommendation for those 65+
if they cannot meet adult guidelines then they should be as physically active as their abilities and conditions will allow
23
principles for promoting calorie balance
-Monitor food and beverage intake, physical activity, and body weight
-Reduce portion sizes
-When eating out, make better choices
-Limit screen time
24
high sodium intake is associated with what condition
high blood pressure
25
where does most dietary sodium come from
salt
26
what is a way to decrease blood pressure
lowering salt intake
27
sodium recommendation reduction
2300mg per day
28
further reduction of sodium to 1500mg per day for what group of people
• Adults ages 51+ yr
• African Americans ages 2+ yr
• People ages 2+ yr with high blood pressure, diabetes, or chronic kidney disease
29
just know that there is no evidence lowering sodium intake to 1500mg per day for certain population is beneficial but there is evidence that reducing sodium intake to 2300mg per day is beneficial
ok thank V nasty!
