    Food Safety:

    Escher ichia co l iO157:H7 An emerging pathogen, now causes infection

    in more than 70,000 people per year

    An extreme case: Video:

    Types o f Vegetar ians

    Macrobiotic: 50% diet is whole grains; other 50% issoups, vegetables, legumes, and seaweed

    Raw Foods: raw produce, nuts, seeds, sproutedgrains and beans, raw dairy products

    Fruitarian: raw fruits, nuts and seeds

    Flexitarian: a vegetarian who occasionally eats meat;being flexible in practice of vegetarianism orveganism. A flexitarian might make only vegetariandishes at home, but eat dishes including meat athome of family or friends

    Hunger Issues

    ~70% of U.S. grain harvest vs. 38% of theworlds grain harvest used to feed livestock

    Typical steer consumes 3000 lbs grain togain 400 lbs in weight, has an output of 50 lbsmanure daily

    Land taken up to grow grain for animal feed

    in addition to land used for pasture instead ofto grow food

    Almost half of worlds farmland being used aspasture for livestock

    Health Aspec ts o f

    Vegetarian Diets Protection against disease is attributed to:

    Diets higher in antioxidants and fiber

    Diets lower in saturated fat and moderate in protein

    Heart Disease

    Antioxidants: higher vitamin C and vitamin E intakes areprotective

    Saturated fat: lower levels are protective

    Cancer Colon: associated with high meat and low fiber diet

    Breast: risk from low fruits/vegetables, high fat

    Hypertension

    Minerals in fruits and vegetables may offer protection

    Protein

    Animal proteins: contains all essential aminoacids

    Plant proteins: missing/low in one amino acid;limiting amino acid

    Complementary proteins combining proteinfoods with different limiting amino acids

    Key to adequate proteins: a diet that is varied

    and adequate in calories (so not necessary to

    be compulsive about complementary proteins)

    Planning the Optimal

    Vegetarian DietDeficiencies most often seen in those with

    overly restrictive diets, so emphasize:

    Nuts and seeds provide antioxidants,calcium, zinc, monounsaturated fats

    Legumes protein, zinc, calcium, fiber

    Omega-3 fats (canola and walnut oil,soy, flaxseed)

    Calcium fortified OJ or soy/rice milk

    Other Tips: If lacto-ovo, dont rely too heavily on

    eggs and cheese

    Go easy on sweets and fried foods Be relaxed about protein combination;

    eating a varied diet will help you to get

    all the amino acids Watch caloric intake of children, teens,pregnant and nursing women

    Insects as Food

    (Entomophagy) Are a direct source of nutrients

    Can add to rural economy

    Can increase food sufficiency of ruralpopulations

    Insect Consumption: Nutrition

    For every 100 grams of dried caterpillars:

    there are ~ 53 grams protein

    ~ 15 grams fat

    ~17 grams carbohydrates

    Energy value ~ 430 kilocalories

    These insects are also believed to have a

    higher proportion of protein and fat than beefand fish with a high energy value

    Agricultural Potential of

    Insects High food conversion efficiency

    Insect production can be done without

    arable land, chemicals or equipment

    Consumption of insects can help withpest management, eliminating the need

    for insecticides

    Barriers to Development of

    Insects for Food Food aversions

    Habitat destruction and water pollution

    Lack of government support andrecognition of concept

    Food and Cul ture

    1 in every 4 Americans is of non-Europeanheritage and 1 in every 10 Americans is

    foreign born. These figures do not includethe millions of undocumented immigrants inthis country

    The population of the U.S is increasingly

    heterogeneous and moving towardsnumerous and diverse ethnic, religious andregional types

    Food and Cul ture

    Each immigrant groups has traditional food habitsthat differ from the so-called American majoritydiet

    Many customs have been influenced andmodified through contact with the majority culture,and in turn have shaped the majority food habits

    Today a fast food restaurant or street stand is aslikely to offer pizza, tacos, egg rolls, falafel as it ishamburgers and hot dogs

    Globalizationis a factor in changing food culture

    worldwide

    Food and Cul ture

    Humans use food symbolically due torelationships, association or convention.What one eats may define who he is. Forexample, in the Middle East, a person whoeats pork is probably a Christian, not a Jew ora Muslim

    Food habits, also called Foodways and FoodCulture, refer to the ways in which humansuse food, including everything from how it isselected, obtained, and distributed to whoprepares it, serves it and eats it

    Food and Cul ture

    Cultural foodsreflect foods that are available.Local ecological considerations: weather, soil,water conditions, geographical features, humanmanipulation of these resources

    For people who immigrate, culturally based foodhabits are one of the last traditions that changethrough acculturation Acculturation: members of one cultural group adopt

    beliefs and behaviors of another group; usually indirection of minority group adopting habits andlanguage patterns of dominant group, but can be

    reciprocal
