2. What are the proven health benefits?
According to the American Dietetic Association:
Decreased Body Mass Index
Lower Rates of Ischemic Heart Disease
Lower Blood Cholesterol
Lower Blood Pressure
Lower Rates of Hypertension, Type II Diabetes, Prostate,
and Colon Cancer
3. Dietary Modifications
Low Cholesterol
Low Saturated Fat Intake
Increased Complex CHO Consumption
Increased Fiber Intake
Increased Folate in the Diet
Numerous Phytochemicals
7. Protein Quality and Quantity
Q. Do plant foods provide the indispensable amino acids?
A.Diets that combine protein sources from a variety of plant
foods will provide the indispensable amino acids.
8. Protein Quality and Quantity
Non-Vegetarian- Average Protein Needs: (10-15% of our diet)
body weight(lbs)/2.2kg x .8gram
Lacto-ovo or Lacto-Vegetarian- Average Protein Needs:
body weight/2.2 x .8-1grams (slight increase)
*Vegan- Average Protein Needs:
body weight/2.2 x 1.3-1.8grams (10% increase)
*Plant proteins are not digested as well as animal proteins.
Infants > 6 yrs old should increase by 15 to 20%
14. Bone health is the main concern.
Enhances Absorption
Increases Calcium
Loss
Protein
Vitamin D
Oxalate: Spinach
Phytate
Excessive sodium intake
Use of diuretics: Caffeine
Excessive animal protein
intake (sulfur containing
AAs)
Soft drinks due to
phosphoric acid
15. Other Factors Promote Bone Health
Vitamins and minerals Exercise
Essential Fatty Acids-may
be protective
Fat soluble vitamins: A,D
& K
Water Soluble B Vitamins
Minerals:
Mg,Mn,Ca,Zn,K,B,&Cu
Must be weight-bearing!
16. The B-12 Challenge
Doesnt naturally occur in plant foods
Must seek out fortified products that contain active B-12
Symptoms of B-12 deficiency are masked due to high folate
levels in vegetarians.
If > 50 yrs, B-12 supplementation is recommended
regardless of diet.
*More B-12 is absorbed when taken in frequent, smaller
amounts compared to one large dose. 5ug of crystalline B-
12= 60% absorption vs. one dose of 500ug = 1%
17. B-12 Sources for Vegetarians
Nutritional Yeast Other Alternatives
*Requires cold
storage and must
be kept away from
light.
18. Omega-3 Fatty Acids
Adequate Intakes (AIs):
Women- 1.1g
Men- 1.6g/day
Vegan- lacks DHA/EPA: No fish is consumed:
AI = 2.2 - 4.4grams/day
N-6: Alpha Linoleic Acid: found abundantly in plants
decreased CD risk; lowers LDL cholesterol.
N-3: Alpha Linolenic Acid: found in fish as a preformed source
of DHA/EPA and is more effective in reducing TAGs than n-6.
19. Sources of Omega-3s in Plants
Ground Flaxseeds
Hempseeds
Canola oil
Walnuts
Soy Beans
DGLVs
Wheat Germ
*Not direct sources of DHA/EPA but the body can convert
them.
