 Stage 1: 140/90 – 159/99
 Stage 2: >160/100
Nutrition Therapy for Hypertension
Dietary Approaches to Stop Hypertension (DASH) flexible and balanced eating plan that has been shown to
lower high blood pressure
 Research shows that the DASH eating plan lowers blood
pressure. The plan:
 Is low in saturated fat, cholesterol, and total fat
 Focuses on fruits, vegetables, and fat-free or low-fat milk and
milk products
 Is rich in whole grains, fish, poultry, beans, seeds, and nuts
 Contains fewer sweets, added sugars and sugary beverages,
and red meats than the typical American diet

Nutrition Therapy for Diabetes
Data from the 2007 National Diabetes Fact Sheet (the
most recent year for which data is available)
 Total: 23.6 million children and adults in the United




States—7.8% of the population—have diabetes.
Diagnosed: 17.9 million people
Undiagnosed: 5.7 million people
Pre-diabetes: 57 million people
New Cases: 1.6 million new cases of diabetes are
diagnosed in people aged 20 years and older each year.

Diagnosing Diabetes
Diabetes – Nutrition Assessment
 Body weight, height, BMI
 Waist circumference
 Men >40 inches and women >35 inches shown increase
in insulin resistance
 Blood pressure
 Lab work
 Hemoglobin A1C
 Fasting glucose
 Urinary glucose

Diabetes – Nutrition
Recommendations
How the body uses CHO
 Carbohydrate foods (grains, starches, fruit, sweets) break
down to GLUCOSE
 Protein foods (meats, nuts, beans) break down to AMINO
ACIDS
 Fat foods (oils, butter, margarine, avocado, bacon) break
down to FATTY ACIDS.
 CHO foods have greatest immediate influence of Blood
Sugar
Diabetes – Nutrition
Recommendations
Campfire illustration
 CHO foods like kindling. Hot fire but goes out. Can result
post meal burn out or lack of energy
 Especially with insulin resistance can often result in low
blood sugar after meals of primarily CHO
 Low blood sugars result in craving sweets & starches
 Headaches – usually resolved by eating
 Protein & Fat are like the big logs that burn slow and make
coals. Extends your energy.
 Strive for a meal that has a mix of CHO foods, lean protein,
healthy fats (ie. olive oil)

Diabetes – Nutrition
Recommendations
Survival Skills
 3 meals per day and 2-3 snacks each day
 Reading a food label, to find CHO content
 Limit sugar in beverages, jello, candy, overt source of
glucose etc.
 Somewhat even distribution of CHO foods per meal
throughout the day to help normalize blood sugars
 Keep a food record for follow up visit and more
detailed instruction and recommendations
Joslin Diabetes Center Nutrition
Guidelines
 Carbohydrates - 40% of total caloric intake - total
should not be less than 130 gm/day
 Fiber - 20-35 gm
 Fat - 30-35 % of total caloric intake
 Saturated fat should be limited to < 10% of total caloric
intake or < 7% in individuals with LDL-Cholesterol > 100
mg/dl
 Polyunsaturated fat should comprise up to 10% of total
calories
 Monounsaturated fat up to 15-20% of total calories.
 Protein 20-30% of total caloric intake
Suggested Macronutrient Distribution

QUESTIONS???
Liver
 A normal liver regulates the proper digestion,
metabloism, and absoprtion of food
 Diseases of the liver can adversly affect gastrointestinal
function and the use of food
Nutrition Therapy for Hepatitis
 Viral hepatitis - inflammation of the liver
 The goal of nutrition management for hepatitis is to
promote liver tissue healing
Nutrition Therapy for Hepatitis
 Protein: 1.2 – 1.5 grams/kg body weight/day
 Carbohydrate: no restriction – monitor glucose and adjust




as necessary
Fat: 30% of calories – restrictions only with maldigestion
due to reduced synthesis and secretions of bile acids
Calories: 25 – 35 kcal/kg body weight/day
Multivitamin supplement at 100% RDAs/DRIs
Fluid and sodium restriction if edema or ascites present
If adequate nutrition cannot be maintained by oral feeding,
enteral feedings or TPN may be indicated
Nutrition Therapy for Cirrhosis
 Cirrhosis is the final stage of certain liver injuries
(alcoholism, untreated hepatitis, bilary obstruction,
drug/poison ingestion)
 Malnutrition, chronic acute hepatitis, and excessive
intake of vitamin A can induce cirrhosis
Nutrition Therapy for Cirrhosis
 Protein: 75 – 100 grams/day (If hepatic coma is not
indicated)
 Sodium: Edema and/or ascites is counteracted 500 – 1000
mg sodium. Fluid intake may be limited
 Texture
 Esophageal varices present – semisolid or liquid diet to avoid
potential rupture
 Tube feedings not advised
 Avoid coffee, tea, pepper, chili powder, or any other irritating
seasonings
 Patients with poor appetite
 Oral nutritional supplements, vitamin/mineral supplements,
electrolyte replacements, parenteral feedings
QUESTIONS???
Gallbladder & Pancreas
 Gallbladder function is to concentrate and store bile
from the liver
 When fat enters the duodenum, it stimulates the
release of bile which helps emulsify fats so they can be
broken down
 When gallstones are present, they block the flow of
pancreatic juices and pancreatitis can occur
 Alcoholism can also cause pancreatitis
Nutrition Therapy for Cholecystitis
(inflammation of the gallbladder)
 Chronic cholecystitis
 Fat/calorie controlled diet
 Adequate amounts of carbohydrates & fiber
 Acute cholecystitis
 Low fat diet
 Decrease gas forming veggies
 Fat soluble vitamins may need to be replaced
 Cholecystectomy
 Fat intake limited for several months
 Introduce fats gradually
Nutrition Therapy for Acute
Pancreatitis
 Goal is to prevent the secretion of pancreatic enzymes
 Start NPO using TPN feedings
 As healing progresses, the diet can progress
 Clear liquid with amino acids, predigested fats
 Bland diet in 6 small feedings
 No stimulants
Nutrition Therapy for Chronic
Pancreatitis
 Low fat diet
 Vitamin and mineral supplementation – especially fat
soluble vitamins (A, D, E, K), and B complex
 Tube feedings or TPN may be necessary
 No alchohol
QUESTIONS???
Kidney Disease
 2 kidneys
 Each the size of your fist
 One on each side of your spine
 Weight 4-6 ounces each
 Nephron - the basic functioning unit of the kidney
 1 million per kidney
38
What do they do?
 Remove waste products and extra fluid from
the blood by forming urine
 Keep blood chemicals in balance
 Produce some of the body’s hormones to
control anemia, blood pressure, and bone
health
39
Diet with CKD – Early Stages
 Protein: To restrict or not to restrict?
 For persons in stages, 1, 2,3 – protein intake is often
limited to 12-15% of each day’s calorie intake or to .8
grams/kg body weight.
 Persons with Stage 4 CKD may be advised to reduce
protein to 10% of calorie intake each day, which is .6.75 grams protein/kg body weight.
40
Phosphorus
 Phosphorus restriction is recommended as soon as an
elevated blood level is seen
 Some experts think 800-1000mg of phosphorus daily is
adequate
41
Potassium
 If the level is high, a low potassium diet is prescribed.
Restricting such foods as avocados, dried fruits
(raisins, apricots, prunes), potatoes, oranges, bananas,
and salt substitutes is often needed.
42
That was the early stages of CKD
Any questions?
43
Treatment for Stage 5
 A treatment for Stage 5 kidney disease
 Blood is cleaned through filtration
 a natural filter inside the body (peritoneal dialysis)
 an artificial filter outside of the body (hemodialysis)
 Dialysis must be done on a regular basis to
replace kidney function
44
Types of treatment
 Peritoneal dialysis
 Hemodialysis
 Transplant
45
Peritoneal Dialysis
 Removes wastes and fluid
 Catheter in the abdomen
 Several exchanges daily
46
Hemodialysis
 Blood circulates through a filter (dialyzer) to remove
wastes and fluid
 A machine controls speed and safety factors
 Hemodialysis can be done in-center or at home, night
or day
 Traditional: At a dialysis facility
 3 treatments/week - 3 to 4 hours each treatment
