Volume (Cardiac Output-CO) Sodium
Increased intake, increased volume Potassium
Balances high blood sodium, promotes kidney excretion of sodium

Rate-Resistance Effects heart muscle cells, rhythmic beating
Calcium Magnesium Potassium
Hypertension affects: Blood vessels Kidneys Eyes Brain
Dash Diet
Adequate potassium, calcium, magnesium whole grains, 4-5 servings/day vegetables, 4-
5 servings/day fruits, 2-3 low-fat dairy 4-5 servings/week of nuts, seeds, legumes 2-3 servings soft margarine-oil/day (1 tsp) 5 or fewer servings sweets/added sugars/week
Moderate Sodium2400 → 1500 mg/day
Atherosclerosis
• Plaque progression – Coronary Heart Disease
(CHD)
– Peripheral Vascular Disease (PVD)
– Carotid Artery Disease (CAD)
– Cerebral Vascular Disease (CVD)- strokes
• Chronic disease• Goal to stop or

Nutrition Related Modifiable Risk Factors
Obesity Elevated LDL, Cholesterol, Triglycerides Low HDL Hypertension Diabetes
Smoking Family history
Nutrition Recommendations
National Cholesterol Education Program- Adult Treatment Panel III Guidelines (NCEP-ATP III) www.nhlbi.nih.gov/guidelines/cholesterol/dskref.htm
Mediterranean Diet American Heart Association
NCEP-ATP III Blood Lipid Goals
LDL (MOST IMPORTANT TO DECREASE) < 100 mg/dL if CHD < 130 mg/dL if 2+ risk factors, < 160 mg/dL if 0-1 risk factors
Cholesterol < 200 mg/dL
HDL < 40 - low; > 60 - high
Triglycerides < 150 mg/dL
NCEP-ATP III Guidelines- TLC Diet
Saturated fat and trans fat < 7% of calories
Cholesterol < 200 mg/day
Increase soluble fiber Increase plant stanols/sterols
2 grams/day Weight Management Physical Activity
Plant Stanols/Sterols
• Modified triglyceride that prevents fat/cholesterol absorption
• Margarine like product
• 2 servings a day
American Heart Association
Weight loss Whole grains- ½ of grain intake Fatty Fish- 2 servings/week; 8 oz total Fat- 25-35% of total calories
Decrease saturated and trans fats Increase mono and polyunsaturated
DietResponse to diet varies per individualResponse depends on patient

InsulinFrom pancreas or injection
CHO from diet, glycogen
Blood Glucose (blood sugar) + Insulin
Cells
Diabetes- Blood Glucose
Hyperglycemia
Elevated fasting blood glucose (sugars) Labs
Normal- 70-110 mg/dL Pre-diabetes- 100-125 mg/dL Diabetes > 126 mg/dL fasting
Pre-Diabetes
Weight loss Exercise
150 minutes/week
General Diet Guidelines ½ grain intake whole grains Increase fiber
25+ grams for women 38+ grams for men
Type 1- Insulin Dependent Diabetes
Pancreas does not make insulin Carbohydrate (CHO) coincides with insulin therapy
@15 grams CHO: 1 unit insulin
Have a CHO intake pattern Count TOTAL grams of CHO Regular (scheduled) meals and snacks Eat more complex carbohydrates than refined
Adult Onset-Type 2 Diabetes
Insulin does not get glucose to cells Insuline resistance
Weight loss Reverses insulin resistance Calorie control, exercise
Balanced Diet Moderate CHO intake Whole grains, limit sugar
Diabetic Hypoglycemia
Low blood glucose < 70 mg/dL 15-15 rule
15 grams CHO, test 15 minutes later ½ cup juice, 1 tablespoon sugar, 1/3-1/2 cup
regular soda/pop Goal to ↑ 50-100 mg/dl in 15 minutes
