Less processed more potassium and less sodium

calcium sources

yogurt, milk, cheese, cereals, spinach, cauliflower

why is calcium and iron in spinach not well absorbed?

oxalate

(bad for absorption) raw in leafy greens, cooked greens is better and higher amt of minerals (iron calcium) cause no oxalate

how can calcium and iron in spinach be better absorbed?

cooked greens cause no oxalate

release of PTH causes calcium to be pulled out from bone

both PTH and vitamin D increase absorption of Ca from SI

increase reabsorption/decrease excretion from kidneys

helps relax muscles

what two interventions can magnesium sulfate be used for?

helps constipation and cuts bruises and relax muscles

what are the sources of heme and non heme iron?

(non heme are plant sources (legumes ex.) (Egg not good for heme) other animal products sources for heme

Heme better absorbed

What vitamin helps with absorption of non-heme iron?

vit. c

What is the main function of iron?

Helps make hemo and myoglobin

What is the term for iron-deficiency anemia and what are its characteristics and symptoms?

microcytic hypochromic anemia

→ involves palor, fatigue, weakness, hyperactivity

How is iron easily stored in the body? Is it easily excreted?

Stored in liver and other organs not readily excreted

what is the role of iodine w respect to thyroid gland?

define energy balance and how does it related to body weight in terms of negative, neutral and positive

the relationship b/w the amt of energy input and the amt of energy output

• negative→ calorie output is exceeds calorie intake=weight loss

• neutral→ calorie intake is = to calorie output, no weight change

• positive→ calorie intake exceeds calorie output= weight gain

what are the four sources of energy intake

carbs (4cal/g), protein (4cal/g) , fats (9cal/g), alcohol (7cal/g)

what are the three sources of energy expended

• BMR (basal metabolic rate)

• thermic effect of food TEF

• PA physical activity

what is the relationship of aging w respect to BMR, LBM, fat tissue, weight gain after 30

bmr decrease

lean body mass decrease

fat tissue increase

1 lb per yr after 30

define the dif. levels of PA

sedentary, light, moderate, high activity

sedentary→ typical desk worker, sleeping, sitting all day

light→ less than 2 hrs

moderate→gym 3x/week, not rlly sitting

high activity→ sports, manual labor, runner

how do each factor affect BMR

decreases

growth increases

physiological stress ?

abnormal thyroid regulation hypo→slow, hyper→fast

fever increase

height increase

extrem temps increases

starving, fasting, malnutrition decreases

weight loss from calorie deficit decreases

smoking nic increases

caffeine increases

medication depends on med

how does weight statistically correlate to health

idk

define and calculate BMI and categories of BMI

bmi is body mass index

categories:

what are the pitfalls of BMI

does not take into account gender, LBM-muscle, bone and water and fat composition

what does research recommend w respect to BMI for the asain pop.

lower cutoff point

body distribution in terms of male and female numerical references

females >35 in.

males >40 in.

= higher chances of mortality and comorbidities

what is the difference b/w visceral and subcutaneous fat

Visceral more toxic and detrimental fat is at wasit visceral @ waist and butt

pre contemplatin and conteplation

what is the dif. b/w ideal and reality of treatment

ideal-m healthy bmi (18.5-24.9)

reality- sustain a weight loss that is 3-5%of initial body weight

A sustained weight loss of 3-5% will decrease the risk of what parameters?

death idk
