Vegetarian Variations

• Lacto Ovo ….No animal flesh Includes dairy/eggs…often high fat!

• Macrobiotic, Pescetarian, Frutarian… etc!

• Vegan……No animal flesh or by-products Fruits, veggies, grains, nuts, beans,

seeds A common diet, but not often chosen!

Can be a very healthy diet

Why isn’t protein a major concern?

Yes

Affirmative!

No problem!!

Of course!!!

You tellin’ me this big hunk gets his protein from plants?

Head’s up if feed infants a vegan diet:• very high protein need (g/lb)• very small stomach capacity

Best diet sources of protein

• Nuts• Grains• Legumes – beans (esp. soy) • Animal flesh• Eggs• Dairy products• Protein supplements Note: often unneeded easy to overdose

$$$

Source of protein…Plant or Animal…determines protein quality!

• Nuts• Grains• Legumes – beans (esp.soy)• Animal flesh• Eggs• Dairy products• Protein supplements whey, casein

soy

Quality: High or low, how do you know?High Quality EAA mix matches human need Animal products and soy (engineered) aka complete

Low Quality EAA mix ≠ our need as a stand alone foodPlant products… grains, nuts, beans, seeds aka incomplete so must combine protein sources

How can you meet protein needs with no animal products/flesh in your diet?

Protein Complementation (PC)• Grains + Legumes (beans)

• Grains…rice, corn, barley, oat, wheat…• Beans…pinto, soy, black, garbanzo…

• Think. Pair. Share. • Think up a few vegan main dish ideas• Include portion size and grams protein• Use My Fitness Pal US favorite

PBJ 18 grams protein 2T. pb + 2 slices

Dave’s Killer bread

Rice and Beans

Corn (grain) and Black Eye Peas

Garbanzos + Wheat (Hummus and Pita)

Why is a plant-based diet environmentally smart ?

Take a break. Be back in ~10

Water/Arable Land: Finite Resources

• Agriculture is largest US/global H2O consumer

• Most U.S. ag land/H2O used for animal production– pasture– grain (corn/soy) acreage (most to cattle in feedlots)

Environmental impact varies by food choice

2015 global pop ~7.2 billion Adding ~80M/yr Most prefer meat-based dietThis diet is ‘resource greedy’Resources inadequate to produce meat-based diet for all

Topsoil Fossil Fuel

Water

For every 100 cal of grain fed to animals…..

• 40 new calories of MILK• 22 new calories of EGG• 12 of CHICKEN• 10 of PORK• 3 of BEEF• It takes ~1/3 cal 1 cal grain

Feedlots

Beef: The Impact

• What does it take to make a pound (16 oz.) burger? aka ‘4x4’ or ‘Double Big Mac’

– ~10 pounds of grain (corn/soy)– ~100 pounds of topsoil– ~ 2, 500 gallons water

‘Thneeds’

• Plan for the future…meat consumption habits will change as resources for production become scarce.

• Improve the balance between your ‘needs’ vs. ‘wants’.

Reduce/eliminate energyintensive, wasteful

(food) products.

Reap benefits of a dietbetter for you/environment; Become more food secure in the process.

The things you THINK you need!

Do Something!

Identify two realistic ways you can

eat more like a vegan.

Veg Up

Try a Meatless MondaySwitch from cow’s milk to soy milkReduce portion/frequency of meat-based mealsBuy local, organic meats and/or 100% pasture

fed beef, not feed-lot beef.Challenge yourself! Eat vegan one meal/day

prior to Nutrition 10 final?!?!?!

Optional Slides

A World Demanding More

• Predict zero growth ~ 2050 global w/pop ~9B • To feed 9B the basics, need 100% crop

production• Why?• Huge production needed because developing

nations growing prosperous, eat more animal products

• Animal products, are non-renewable-resource-hungry and polluting to produce!– fossil fuels, fresh water, topsoil, high waste

productio

Environmental Cost to Produce Meat

• Land damage– erosion, overgrazing, deforestation

• Intensive water use (feed grain and animal production)

• Air/water pollution (manure, drugs, greenhouse gases**)

• Biodiversity ; resistant species• Heavy fossil fuel use

Can you order these by protein content???

• Bean Burrito• Hamburger 4oz. and bun with

toppings• Peanut butter and jelly sandwich• Tofu vegetable stir fry• Chicken pot pie• Oatmeal and soy milk 1 Cup

Early vegetarians returning from the kill !

Farmer Bill found that the cows had built their own electric fence.

Maybe the cows knew before we did that we’ve been eating too much meat.
