Causes include: physical and mental illness, job loss, alcohol, drugs, lack of awareness of food assistance programs
Estimated 1 out of 7 households in the US experience hunger or threat of hunger
Estimated 15% in the U.S. live in poverty
Estimated 1 out of 6 children in the U.S. live in poverty

High Food security is access to enough food to support an active and healthy lifestyle.
Food insecurity is limited or uncertain access to sufficient quantity or quality of food to sustain a healthy and active life.
Food insufficiency is defined as having too little food.
Food poverty is defined as hunger resulting from inadequate access to food.

Relieving Hunger in the US Federal Assistance Programs
1 of every 5 Americans receives food assistance
WIC
School lunch
Congregate meals
SNAP –Supplemental Nutrition Assistance Program Debit card used for food, food bearing plants, seeds
Cannot use for alcohol, tobacco, cleaning items, or nonfood items
60 billion dollars per year are spent on these programs

Relieving Hunger in the US National Food Recovery Program
Feeding America
Collects good food that would normally go to waste from restaurants, fields, commercial kitchens, grocery stores
Coordinates distribution to food pantries, shelters and soup kitchens

World Hunger Food Shortages
Political turbulence and government policies during famine affect food problems.
Armed conflicts may interfere with humanitarian efforts to get food to people.
Natural disaster areas accept food assistance from other countries.

World Hunger Malnutrition
Affects 850 million people
7.6 million children die annually from malnutrition as a result of diarrhea and dehydration
Iron, iodine and vitamin A are the nutrients most lacking.
100 million children suffer from Vitamin A deficiency
More than 30% of the world’s population have iron deficiency anemia
20% suffer from zinc deficiency
Protein-kcalorie malnutrition

World Hunger
Malnutrition Develop dysentery, cholera, pneumonia, whooping
cough, measles, and malaria
Oral-rehydration therapy (ORT) can reverse dehydration.
A diminishing food supply is a problem as populations continue to grow.

Malnutrition
Protein deficiency Slowed growth, impaired brain and kidney function, poor
immunity, poor nutrient absorption
Protein-Energy Malnutrition (PEM) Deficient in protein, energy, or both
Most often strikes children Affects 1 in 4 children worldwide under age 5 (25%)
Most of the 20,000 children who die each day are malnourished
Poor growth in children
In adults, wasting and weight loss occur

Protein Malnutrition
Most prevalent in Africa, Central America, South America, Middle East, East and Southeast Asia
In the US– the homeless, poverty, elderly, drug and alcohol addiction
Prevalent in AIDS, tuberculosis, anorexia
7.6 million children under five die in developing countries each year. Malnutrition and hunger-related diseases cause 60 percent of the deaths; (Source: The State of the World's Children, UNICEF, 2007)

Malnutrition
Malnutrition Infections
Lack of antibodies to fight infections
Fever
Fluid imbalances and dysentery
Anemia
Heart failure and possible death
Rehabilitation Rehydration
Nutrition intervention must be cautious, slowly increasing protein.
Programs involving local people work better.

Poverty and Overpopulation Poverty and hunger with more people to feed
interrelate to each other.
To break this cycle requires improving the economy and providing education, health care, and counseling about family planning.
Population Growth Leads to Hunger and Poverty Human carrying capacity – the maximum number of people
the earth can support

Poverty and Overpopulation Hunger and Poverty Lead to Population Growth
Poverty leads to inadequate food and shelter, physical abuse, forced marriages, and prostitution.
Lack access to reproductive care and family counseling
Families depend on children to farm the land, carry water, and care for the elderly.
With high death rates in children, parents may choose to have more children with hopes that some will survive to adulthood.
