  • Weight management/calorie restriction
  • Assessment of visceral fat
  • Whole grains
  • Magnesium
  • Omega 3 fatty acids
  • Calcium and vitamin D
  • Plant sterols/stanols

3
Nutrition Assessment
  • Physical assessment nutrition analysis
  • Acanthosis nigricans
  • BMI/ Waist circumference
  • EAL fair/imperative
  • Dietary patterns
  • Whole grains
  • Low glycemic foods
  • Omega 3
  • Dairy
  • Consumption of plant sterols
  • Lab values
  • Vitamin D
  • Magnesium
  • Lipid profile
  • Liver enzymes

4
Reduction in the incidence of type 2 diabetes
with lifestyle intervention or metforminNEJM
346393, 2002
  • Standard lifestyle recommendations
  • Written information regarding food pyramid, NCEP
    step 1 diet and annual 30 min individual session
  • Intensive lifestyle intervention
  • 16 lesson individualized curriculum 11 during
    the first 24 wks, flexible, culturally sensitive
    group sessions

5
Reduction in the incidence of type 2 diabetes
with lifestyle intervention or metforminNEJM
346393, 2002
  • Average f/u 2.8 yrs
  • Incidence of diabetes 11/100 p-yrs with placebo,
    7.8 with metformin (31 reduction) , 4.8 with
    lifestyle intervention (58 reduction)
  • To prevent 1 case of diabetes, 6.9 persons would
    have to be treated with lifestyle modification,
    13.9 with metformin

Physical Assessment
  • BMI
  • Waist circumference
  • gt 40 inches in men
  • gt 35 inches in women
  • Normal weight/metabolically obese
  • Waist to hip ratio

9
Physical Assessment
  • Acanthosis nigricans
  • Caused by the influence of insulin on the
    melanocytes
  • Not a hygiene issue

Waist circumference and 8 year incidence of
metabolic syndrome

11
Visceral fat the fat you cant see, or can you?
Visceral fat is white
12
Calorie restriction
  • Central to the treatment of metabolic syndrome
  • Reduces hyperinsulinemic response
  • Weight loss of 5-10 of initial weight can yield
    significant improvement of metabolic parameters
  • Questions remain
  • Should pathophysiology direct MNT
  • Optimal macronutrient distribution
  • Dietary patterns vs individual components
  • Glycemic load
  • Fortified foods with plant stanols
  • 2 grams per day can lower LDL by 10

13
How much weight loss will have an impact ?
14
Does insulin status predict diabetes?
Low Insulin secretion, 15.9
Neither 1.5
Poor secretion and insulin resistance 54
Insulin resistant good secretion 28
15
Caloric Restriction Acutely Lowers HDL-C Level
  • Trials of very-low-calorie diets show that HDL-C
    levels decrease by 212 mg/dL during acute
    caloric restriction.
  • After 12 wks, HDL-C returned to pretreatment
    range, and this trend was still apparent after 1
    year.
  • Therefore, benefits of weight-loss programs
    should not be assessed during acute caloric
    restriction.

Rössner S, et al. Atherosclerosis.
198764125130.
16
Weight and HDL-C
  • Inverse correlation between body weight and HDL-C
    is consistently observed in both men and women.
  • For every 3 kg (7 lb) of weight loss, HDL-C
    levels increase 1 mg/dL.

Dattilo AM, Kris-Etherton PM. Am J Clin Nutr.
1992 56320328
17
Macronutrient Distribution
  • Low carbohydrate diets(lt20 CHO)
  • Some evidence of short term benefit(6 weeks)
  • Ketogenic diets have no distinct advantages over
    lowering restriction of total carbohydrate
  • Ketogenic diets may increase inflammatory risk
    and reduce exercise capacity
  • 40 carbohydrate equally effective as traditional
    low carbohydrate diets in reducing body weight
    and insulin resistance

Am J Clin Nutr 2006 85238-9
18
Definition GI-Quality of CHO
  • the incremental area under the blood glucose
    response curve of 50 grams of available CHO from
    a test food, expressed as a percentage of the
    response to the same amount of CHO from a
    standard food (bread or glucose), taken by the
    SAME person
  • Thomas M.S. Wolevar, DJA Jenkins

19
Concept of Glycemic Load (GL)-Quantity of CHO
  • GI refers to single CHO source
  • Captures the quality of the CHO
  • Glycemic Load
  • GI x Amt of CHO in a serving
  • GL captures the quantity of CHO
  • Brown rice contains 18 gms CHO, GI 73
  • GL for brown rice 18 x 73 or a glycemic load
    of 13
  • Each GL 1 gram of glucose

20
Not as simplistic as less processed foods are
low GI
21
Glycemic load Weight loss or something else?
  • Insufficient data in the Evidence Analysis
    Library to implement as a weight loss strategy.
  • Are there benefits beyond weight control?
  • Lowering the GI of a high carbohydrate diet
    improves beta cell function in those with IGT

Epidemiologic studies reported on GI

Decreased HDL Increased TG Increased C-reactive protein Increased Risk of diabetes Increased Risk of CVD
Wolevar, 1992 Luscombe, 1999 Buyken, 2001 Liu, 2001 Ford, 2001 Frost, 1999 Liu, 2001 Liu, 2002 Hu, 2001 Salmeron, 1997 Salmeron, 1997 Schulze, 2004 Liu, 2000
24
Glycemic load and liver steatosis
  • Links between insulin resistance and liver
    steatosis
  • High GI diets are associated with increasing
    prevalence of liver steatosis

Am J Clin Nutr 84136-42
25
Framingham Offspring Cohort Study
  • 2834 subjects assessed for carbohydrate related
    factors and the prevalence of metabolic syndrome.
  • Total fiber, cereal fiber, fruit fiber and whole
    grains were were inversely associated with
    insulin resistance.
  • Elevated glycemic index/glycemic load diets
    positively associated with IR
  • Whole grains may reduce the risk of MetS

26
Whole Grains, Fiber Magnesium
  • Dietary patterns rich in whole grains provide 3
    nutrients linked with a decreased incidence of
    metabolic syndrome and improved biochemical
    parameters
  • In a study of adults in Tehran, the higher the
    intake of whole grains the lower the prevalence
    of metabolic markers.
  • Cereal fiber has been linked with a decrease in
    MetS

27
Magnesium
  • Recent studies have demonstrated the role of
    magnesium as a risk factor for MetS
  • NHANES III and and the CARDIA study both
    demonstrated an inverse relationship between
    magnesium intake and MetS. Highest quartile of
    Mg intake reduced prevalence by 31
  • No toxicity from whole food
  • UL 350 mg

28
AHA Recommendations for Omega-3 FA Intake
Population Recommendation
Patients without documented CHD Eat a variety of (preferably oily) fish at least twice a week. Include oils and foods rich in ?-linolenic acid (flaxseed, canola, and soybean oils flaxseeds and walnuts)
Patients with documented CHD Consume 1 g of EPADHA per day, preferably from oily fish. EPADHA supplements could be considered in consultation with the physician
Patients needing triglyceride lowering 24 grams of EPADHA per day provided as capsules under a physicians care
Kris-Etherton PM et al. Circulation
20021062747-2757.
29
Vitamin D
  • Vitamin D receptor are found on the nucleus of
    the cell and the cell membrane
  • Essential in the function of the beta cell
  • Adequate blood levels, not dietary intake can
    improve insulin sensitivity by 60
  • A 30 year prevention program of Type 1 diabetes
    indicates an 80 reduction in disease with 2000
    IU of vitamin D
  • Obesity is a risk factor for deficiency as it is
    sequestered in adipose tissue

Harris, SS J Nutrition 2005 135 (2)323-5
30
Vitamin D
  • Adequate blood levels are more effective than the
    diabetes medications metformin or TZDs
  • A study of postmenopausal women taking
    bisphosphonates for osteoporosis and 400 IU of
    vitamin D
  • 18 had levels less than 50 nmol/L and 52 had
    values lt 75nmol/L
  • Serum 25(OH) levels above 80nmol/L considered
    optimal

31
Cost of the Metabolic SyndromeResearch Options
  • The Cardiovascular Health Study
  • 10 year medical costs of individuals 65 and
    older
  • NCEP definition
  • Metabolic syndrome present in 47 of the sample
  • Costs to Medicare 20 higher with metabolic
    syndrome
  • Represents an outcome based intervention for
    RDs, nurses and other health care providers
  • Adherence to 2005 Dietary Guidelines are
    effective for reducing MetS risk in women

32
Summary
  • Assessment patterns for RD/RN should include the
    following
  • Visceral fat via waist circumference
  • Dietary patterns
  • Whole grains
  • Magnesium, fiber
  • Dairy products
  • Calcium and vitamin D
  • Glycemic load
  • Plant stanols
