Vegetarian Nutrition 101: Vegetarian Nutrition 101
More than 12 million people in the US are vegetarians, and 19,000 more make the switch to a meat-free diet every week
Vegetarian diet facts: Vegetarian diet facts Top three killers in U.S. right now ALL related to diet: CVD, stroke, cancer
According to T. Colin Campbell, director of the largest epidemiological study in history:
“The vast majority of all cancers, cardiovascular disease, and other forms of degenerative illness can be prevented simply by adopting a plant-based diet.”
Heart disease, cancer, strokes, diabetes, osteoporosis, obesity, and other diseases have all been linked to meat dairy consumption

Only animal-derived foods have cholesterol, so a pure vegetarian diet= cholesterol free!
American Dietetic Association Position on Vegetarian Diets: American Dietetic Association Position on Vegetarian Diets Position Statement:
It is the position of The American Dietetic Association (ADA) that appropriately planned vegetarian diets are healthful, are nutritionally adequate, and provide health benefits in the prevention and treatment of certain diseases.
Other health organizations have said…: Other health organizations have said… The American Cancer Society, the American Heart Association, the Heart and Stroke Foundation of Canada, the National Institutes of Health, and the American Academy of Pediatrics all recommend choosing a diet based on a variety of plant foods—grains, vegetables, fruits, and legumes.
The New Four Food Groups: The New Four Food Groups
The New Four Food Groups: The New Four Food Groups Vegetables: 4 or more servings per day
Legumes (beans, peas, lentils): 3 servings per day
Whole grains: 8 small servings (or 4 normal servings) per day
Fruits: 3 or more servings per day
The New Four Food Groups: The New Four Food Groups Tips for achieving these serving sizes:
Let grains fill up about ½ your plate
Let vegetables fill up ¼
Let beans fill up ¼
Let fruit be a dessert or snack
(or pile the vegetables high; reduce the grains)
Calories: Calories Calories made of: carbohydrates, protein, and fat
How many calories do you need each day?
Total calories= BMR + energy for activity
Calories: Calories BMR (basal metabolic rate): BW x 10
Energy for activity:
Not very active: BMR x 20%
Lightly active: BMR x 30%
Moderately active: BMR x 40%
Very active: BMR x 50%
Calories: Calories Example: a 140-lb., lightly active woman
BMR calories: 140 x 10= 1400 +
Activity calories: 1400 x 30% = 420
Total calories needed to maintain current weight = 1400 + 420 = 1820 calories
To lose weight/gain weight: +/- 500 calories a day
(1 lb. = 3500 calories)
Carbohydrates: Carbohydrates Main source of calories in a healthy diet
Primary fuel source for brain and muscles; helps maintain functioning of nervous system
Approximately 55-75% of daily calories should come from carbohydrates
Carbohydrates: Carbohydrates Two types of carbs: Simple and Complex
Simple carbs (sweets): quickest source of energy (lack fiber)
Ex: table sugar, brown sugar, honey, maple syrup, molasses, jams/jellies, fruit juices
Carbohydrates: Carbohydrates Complex carbs: rich in fiber, high in vitamins and minerals, important for digestion and elimination
Examples: vegetables, fruits, grains, potatoes, beans
Key to a healthy diet: Focus on COMPLEX CARBS!!!
Fiber: Fiber AKA: “plant roughage” (the part of beans, grains, vegetables, and fruits that resists digestion)
Only found in plant food
Helps rid the body chemicals (including hormones); lowers cholsterol
One of the reason vegetarians have significantly lower rates of cancer, heart disease, diabetes, and are usually slimmer than other people
(fiber helps you fill UP so you don’t fill OUT!!)
Fiber: Fiber
Studies show that every 14 grams of fiber in your daily diet reduces your calorie intake by about ten percent.
Fiber: Fiber Aim for 40 grams of fiber/ day
Good sources:
BEANS/LENTILS: each half-cup serving of beans or lentils ~ 7 g; one cup soymilk/ ½ cup tofu~ 3 g
Vegetables: 1 cup ~ 4 g;
Fruit: each medium-sized fruit ~ 3 g
Grains: each piece of white bread, bagel, 1 cup white rice ~1g; 1 cup brown rice ~ 2 g; 1 cup oatmeal ~ 4 g; ready-to-eat cereals ~ 3 g; Bran ~ 8 g.
FAT: FAT Most concentrated source of calories in food you eat
Should not exceed 30% of calories
(2000 calorie diet: < 60 g/ day)
But, research has shown that: the lower your fat intake, the better your chances of warding of heart disease, cancer, and keeping a slim waistline
FAT: FAT Made of 3 types of fatty acids: monounsaturated, polyunsaturated, saturated
Goal: Minimize saturated fats and trans fats (that raise blood cholesterol levels)
Saturated fat in:
foods of animal origin (beef, pork, lamb, poultry, eggs, milk, butter, cheese, sour cream, etc.)
plant foods: coconuts, coconut oil, palm oil, palm kernel oil, chocolate, cocoa butter
FAT: FAT Monounsaturated fats:
olives/oil, almonds/oil/butter, canola oil, hazelnuts, peanuts/oil/PEANUT BUTTER!
Polyunsaturated fats:
sesame seeds/oil/butter, sunflower seeds/oil, safflower oil, corn oil, walnuts/oil, soybeans and soy products (tofu, tempeh, TVP), flax seeds/oil
FAT: FAT Fat in foods (% of calories)
Atlantic salmon 40
Beef, round bottom, lean 28
Chicken white meat, skinless 23
Tuna, white 21
Broccoli 12
Rice, brown 8
Apple 6
Beans, navy 3
Essential Fatty Acids: Essential Fatty Acids There are two PUFAs that are EFAs:
Linolenic acid (omega-3)
Linoleic acid (omega-6)
Important for vascular health: blood vessel dilation/constriction, blood clots, inflammation
Lack of EFAs associated with: depression, poor immune function scaly skin, reduced growth, kidney and liver problems
EFAs: EFAs DRIs:
Omega-3’s: 1-2% of calories
Omega-6’s: 5-8% of calories
More important: ratio
Ratio of Omega-3’s: Omega-6’s should be:
1:3
(most Americans consume them in 1: 10 ratio; we need to increase Omega-3’s)
EFAs: EFAs Omega-6 sources: seeds, nuts, vegetable oils
Omega-3 sources: soybean oil, canola oil, flaxseed oil, walnuts
**best source: flaxseeds:
2 tablespoons/day of flaxseeds is recommended
Flaxseed oil…………………………………………………53-62%
Linseed oil…………………………………………….……53%
Canola oil……………………………………………………11%
Walnut oil…………………………………………………..10%
PROTEIN: PROTEIN
Approximately 10-15% of calories should come from protein
PROTEIN: PROTEIN Myth: “I can’t get enough protein as a vegetarian.”
PROTEIN: PROTEIN Fact:
The American Dietetic Association holds that a diet that includes a variety of healthy plant foods provides all the protein you need.
Protein needs might be higher for those who consume protein from sources that are less well digested (cereals and legumes); however, typical protein intakes of lacto-ovo vegetarians and vegans have been shown to meet and exceed protein requirements
PROTEIN: PROTEIN Dispelling the myth:
The average American consumes DOUBLE the protein his/ her body needs
The main sources of protein consumed tend to be from animal products, which are also high in saturated fat and cholesterol
Vegetarians do not need to combine foods at each meal to a get “complete” protein; should eat a wide variety of plant protein sources throughout the day
(grains, legumes, vegetables, nuts, and seeds can provide ALL the essential amino acids)
Soy= complete and high quality source of protein; contains isoflavonoids= act as antioxidants & phytoestrogens to reduce the risk of cancer, CVD, and osteoporosis
Protein for Athletes: Protein for Athletes Dispelling the myth:
According to the US DRI committee, a higher RDA is not warranted for healthy adults doing resistance or endurance exercise
Because Americans, on average, consume much more protein than they actually need, any increased need for athletes is most likely already being met
While muscle fibers are protein, dietary protein is not needed for muscle growth (muscle growth is fueled by carbs and fat before protein even comes into play)
Excess protein= excess calories= adds weight as FAT, not muscle (slows down performance)
PROTEIN: PROTEIN It’s almost IMPOSSIBLE to be deficient in protein; here’s how:
Eating excess junk food/ filling diet with “empty” calories (fatty, highly refined, and processed foods, excess alcohol)
Trying to live on fruit alone
Not taking in enough calories
PROTEIN: PROTEIN 20 different amino acids
11 made by our body
= 9 essential amino acids
(must be obtained through diet)
PROTEIN: PROTEIN RDA for average sedentary adult=
BW (body weight) x 0.36
Active adult: BW x 0.4-0.6
Growing athlete: BW x 0.6- 0.9
Adult building muscle mass: BW x 0.6-0.9
PROTEIN: PROTEIN Example:
A sedentary adult who weighs 15o lbs. needs 54 g/ day
What does this look like?
1 bowl Raisin Bran and 1 cup Soymilk (12 g) +
1 Veggie Burger on Whole Wheat Bun (20g) +
1 cup Pasta with 1 cup assorted vegetables and beans (22 g) =
54 grams of protein!
PROTEIN: PROTEIN Protein checklist. Aim for:
5 or more servings of grain each day (1 serving= 1 slice bread; ½ cup cereal) ~3 g
3 or more servings of vegetables each day (1 serving= ½ cup cooked vegetables) ~2 g
2-3 servings of legumes (1 serving= ½ cup cooked beans, 10 oz. nuts, 1 cup soy milk) ~ 4-10 g
PROTEIN: PROTEIN 1 cup kidney beans………………………………..15 g
1 cup lentils…………………………………………..18 g
½ cup tofu……………………………………………14 g
1 cup soymilk (Silk)………………………………..6 g
1 veggie hot dog (Yves Veggie Dogs)……… 16 g
1 veggie burger (Boca burger)….................13 g

PROTEIN: PROTEIN Problems with too much protein:
Osteoporosis
Kidney Disease
Cancer
CVD
PROTEIN: PROTEIN THE ATKINS DIET:
ADA: “nightmare”
How it works = ketosis
Hard to sustain; complaints of: fatigue, nausea, reduced appetite
Low in vitamins, minerals
High in saturated fat and cholesterol
Causes bad breath
Weight returns quickly after cessation
CALCIUM: CALCIUM Necessary for bone health, muscle contraction, nerve impulse transmission, blood clotting, cell metabolism
Deficiencies= osteoporosis
AI: 1,000 mg/day (for adults 19-50)
UL: 2,500 mg/day
CALCIUM: CALCIUM Calcium retention:
In order to retain calcium:
Decrease animal protein:
animal protein has been found to increase calcium excretion: for every gram of animal-derived protein we consume, we lose 1 mg of calcium; soy protein does not have this effect
Numerous studies link increased animal protein consumption to increased risk for osteoporosis
CALCIUM: CALCIUM To retain calcium:
Decrease sodium intake because sodium increases calcium losses: for every gram of salt we consume, we lose 5-10 mg of calcium
Increase weight bearing exercise activity (walking, running, aerobics) to promote strong, health bones
Osteoporosis: vegan diets are preventative
CALCIUM: CALCIUM Good sources:
Soy products (yogurts, milk, beans, tempeh, and tofu)
Green leafy vegetables
(except spinach, Swiss chard, and beet greens)
Legumes (beans, peas, lentils)
Calcium-fortified breads, cereals, and grains
CALCIUM: CALCIUM ½ cup cultured soy yogurt, fortified………367 mg
1 cup cooked collards……………………………365 mg
1 cup cooked broccoli……………………………178 mg
1 cup navy beans…………………………………..130 mg
½ cup Tofu (Nasoya firm) …………………… 200 mg
1 cup fortified plant milk (Silk, Westsoy
Plus, Rice Dream) ……………………………… 300 mg
1 cup calcium fortified orange juice………..300 mg
1 serving Total breakfast cereal…………….1000 mg
1 T blackstrap molasses………………………….170 mg
Iron (Fe): Iron (Fe) Oxygen transportation, enzyme component, immune function, brain function
RDA: for men: 15 mg /day
for women: 32mg/ day
UL: 40 mg/day (>40= increased cancer risk)
**RDA value for vegetarians is 1.8 times for non-vegetarians
IRON : IRON Myth:
ANEMIA
Fact:
People eating vegetarian diets are no more likely to be iron deficient than people who eat meat
IRON: IRON Dispelling the myth:
Two kinds of iron: heme and non-heme; non-heme is less absorbable
Meat= 40% heme; 60% non-heme
Vegetable sources= 100% non-heme
Iron: Iron Dispelling the myth cont’d:
--BUT--
Vegetable foods have MORE Fe/calories of food than meat
(ex: 340 calories of sirloin steak = 100 calories of spinach)
Vitamin C increases non-heme absorption by 6-fold = absorption of non-heme iron is as good if not better than heme iron
Most vegetables that are high in Fe are also high in Vitamin C; meat and dairy= no Vitamin C
Iron: Iron Good sources:
Soy foods (soy beans, meats, & milks)
Legumes (beans, peas, lentils)
Nuts/Seeds and their butters
Green leafy vegetables (except for spinach, Swiss chard, and beet greens)
Dried fruits
Whole grains and iron-enriched grains and cereals
Iron: Iron 1 cup cooked chickpeas……………………6.8 mg

½ cup tofu (Nasoya firm)…………………...2.1 mg
1 veggie hot dog (Yves Veggie Dogs)..…...4.5mg
1 cup cooked kale…………………….........1.2 mg
10 dried apricot halves or 4 dried figs……1.7 mg
¼ cup pumpkin seeds………………………5.2 mg
1 cup Cheerios……………………………….4.5 mg
1 cup Total cereal…………………………….15 mg
Vitamin B-12 (cobalamin): Vitamin B-12 (cobalamin) Decreases risk for heart disease, aids in fat metabolism, important of nerve function
Lack of B-12 can result in fatigue, anemia, impaired nervous system functioning, and can increase the risk of infection
B-12: B-12 RDA: 2.4 mg/day
Made by bacteria in the small intestine of animals; only meat, poultry, fish, and dairy contains B-12
Vegans: no problem!
Storage: vegans who previously ate animal-based foods have B-12
stores that will not be depleted for 20-30 years or more
Fortified foods: cereals, soymilks, soy meats, nutritional yeast
Multi-vitamin (recommended!)
**consume small amounts at frequent intervals
