Unit 12. Food and Nutrition Issues
12.6 Hunger and Food Insecurity
Government agencies also play an important role in addressing hunger via federal food-assistance programs. The agencies provide debit cards (formerly distributed in the form of food vouchers or food stamps) to consumers to help them purchase food and they also provide other forms of aid to low-income adults and families who face hunger and nutritional deficits. This topic will be discussed in greater detail later in this section.
What is Hunger?
Hunger has two meanings. The first relates to appetite and is the body’s response to a need for nourishment. Through stomach rumbling, the body alerts the brain to eat . This uneasy sensation is easily addressed with a snack or a full meal. A second definition of “hunger” relates to a weakened condition that is a consequence of a prolonged lack of food. People who suffer from this form of hunger typically experience malnourishment, along with poor growth and development.
Adequate food intake that meets nutritional requirements is essential to achieve a healthy, productive lifestyle. However, millions of people in North America, not to mention globally, go hungry and are malnourished each year due to a recurring and involuntary lack of food. The economic crisis of 2008 caused a dramatic increase in hunger across the United States.[1] The high inflation rates after the pandemic of 2020 has resulted in a similar increase in hunger.
According to the Food and Agriculture of the United nations (FAO), “close to 12 percent of the global population was severely food insecure in 2020, representing 928 million people – 148 million more than in 2019. [2]” Although this was a decrease from a historic high of more than one billion people from the ten years earlier , it is still an unbearable number. Every night, millions and millions of people go to sleep hungry due to a lack of the money or resources needed to acquire an adequate amount of food. A number of terms are used to categorize and classify hunger. Two key terms, food security and food insecurity, focus on status and affect hunger statistics. Another term, malnutrition, refers to the deficiencies that a hungry person experiences.
Food Security Versus Food Insecurity
Most American households are considered to be food secure, which means they have adequate access to food and consume enough nutrients to achieve a healthy lifestyle. However, a minority of US households experiences food insecurity at certain points during the year, which means their access to food is limited due to a lack of resources to meet nutritional needs.
According to the USDA, about 48.8 million people live in food-insecure households and have reported multiple indications of food access problems. About sixteen million of those have “very low food security,” which means one or more people in the household were hungry at some point over the course of a year due to the inability to afford enough food. The difference between low and very low food security is that members of low insecurity households have reported problems of food access, but have reported only a few instances of reduced food intake, if any.[3] African American and Hispanic households experience food insecurity at much higher rates than the national average.[4]
Households with limited resources employ a variety of methods to increase their access to adequate food. Some families purchase junk food and fast food—cheaper options that are also very unhealthy. Other families who struggle with food security supplement the groceries they purchase by participating in government assistance programs. They may also obtain food from emergency providers, such as food banks and soup kitchens in their communities.
Malnutrition
A person living in a food-insecure household may suffer from malnutrition, which results from a failure to meet nutrient requirements. This can occur as a result of consuming too little food or not enough key nutrients.
Worldwide, three main groups are most at risk of hunger:
- the rural poor in developing nations who also lack access to electricity and safe drinking water,
- the urban poor who live in expanding cities and lack the means to buy food, and
- victims of earthquakes, hurricanes, and other natural and man-made catastrophes.[5]
In the United States, there are additional subgroups that are at risk and are more likely than others to face hunger and malnutrition. They include low-income families and the working poor, who are employed but have incomes below the federal poverty level.
Senior citizens are also a major at-risk group. Many elderly people are frail and isolated, which affects their ability to meet their dietary requirements. In addition, many also have low incomes, limited resources, and difficulty purchasing or preparing food due to health issues or poor mobility. As a result, more than six million senior citizens in the United States face the threat of hunger.[6]
One of the groups that struggles with hunger are the millions of homeless people across North America. According to a recent study by the US Conference of Mayors, the majority of reporting cities saw an increase in the number of homeless families.[7] Hunger and homelessness often go hand-in-hand as homeless families and adults turn to soup kitchens or food pantries or resort to begging for food.
Rising hunger rates in the United States particularly affect children. Nearly one out of four children, or 21.6 percent of all American children, lives in a food-insecure household and spends at least part of the year hungry.[8] Hunger delays their growth and development and affects their educational progress because it is more difficult for hungry or malnourished students to concentrate in school. In addition, children who are undernourished are more susceptible to contracting diseases, such as measles and pneumonia.[9]
Government Food Assistance Programs
Because hunger and food shortages were common during the Great Depression, the federal government established the first Food Stamp Program in 1939. The food assistance program was short-lived, ending in 1943 when the US entered World War II. Food Stamps were reintroduced during the 1960s then renamed the Supplemental Nutrition Assistance Program (SNAP) in 2008. Numerous changes have been made to SNAP since that time. [10] and are similar to the program that exists today. ended a number of programs that work to alleviate hunger and ensure that many low-income families receive the nutrition they require to live a healthy life. Programs designed for children were strengthened by the passage of the Healthy, Hunger-Free Kids Act of 2010. This legislation authorized funding and set the policy for several key core programs that provide a safety net for food-insecure children across the United States.
The federal poverty level (FPL) is used to determine eligibility for food-assistance programs. This monetary figure is the minimum amount that a family would need to acquire shelter, food, clothing, and other necessities. It is calculated based on family size and is adjusted for annual inflation. Although many people who fall below the FPL are unemployed, the working poor can qualify for food programs and other forms of public assistance if their income is less than a certain percentage of the federal poverty level, along with other qualifications. (The first three programs listed below are funded by USDA and the Elderly Nutrition Program is funding through the US Administration on Aging.)
The Supplemental Nutrition Assistance Program
Formerly known as the Food Stamp Program, the Supplemental Nutrition Assistance Program (SNAP) provides monthly benefits for low-income households to purchase approved food items at authorized stores. Clients qualify for the program based on available household income, assets, and certain basic expenses. In an average month, SNAP provides benefits to more than forty million people in the United States.[11] The program provides Electronic Benefit Transfers (EBT) which work similarly to a debit card. Clients receive a card with a certain allocation of money for each month that can be used only for food. In 2010, the average benefit was about $134 per person, per month and total federal expenditures for the program were $68.2 billion.[12] Because of skyrocketing inflation in the 2021, the average benefit increased to an astounding $216 per person.[13]
The Special, Supplemental Program for Women, Infants, and Children
The Special, Supplemental Program for Women, Infants and Children (WIC) provides food packages to pregnant and breastfeeding women, as well as to infants and children up to age five, to promote adequate intake for healthy growth and development. Most state WIC programs provide vouchers that participants use to acquire supplemental packages at authorized stores. In 2010, WIC served approximately 9.2 million participants per month at an average monthly cost of about forty-two dollars per person.[14]
The National School Lunch Program
The National School Lunch Program (NSLP) and School Breakfast Program (SBP) ensure that children in elementary and middle schools receive at least one healthy meal each school day, or two if both the NSLP and SBP are provided. According to the USDA, these programs operate in over 101,000 public and nonprofit private schools and residential child-care institutions.[15] In 2010, the programs provided meals to an average of 31.6 million children each school day. Fifty-six percent of the lunches served were free, and an additional 10 percent were provided at reduced prices.
Senior Nutrition Programs
For many years, we have recognized that good nutrition is essential for healthy aging. However, many older adults are malnourished because of low income, lack of transportation to grocery stores, and declining physical and mental health. To alleviate the problem, the Older Americans Act (OAA) Nutrition Program provides funding to serve a healthy meal five days a week for individuals aged 60 or older.
Since 1972, the Senior Nutrition Program has served hot meals five days a week to many needy senior citizens. Unlike the other food assistance programs, the OAA Nutrition Program is under the direction of the Administration on Aging of the US Department of Health and Human Service, not USDA. The OAA requires that states have designated Area Agencies on Aging that are comprised of several counties in each state. The meal programs are administered under the Area Agencies. The federal government pays for about one-third of the program; the remaining funds are from private grants or other local sources.
Meals are provided in one of two ways, one for the home-bound and the second for those who are healthy enough to eat at a senior center or another community center.
- Home-delivered meal, sometimes known as Meals on Wheels, helps sick, home-bound older adults by delivering a hot meal each weekday. The volunteers who deliver meals to the frail elderly, often visit with the older adult, and ensure the senior citizen is safe.
- Congregate meals are served at senior centers or a similar facility. In addition to providing a nutritious meal, the congregate meals allow time for older adults to meet and socialize with others.
Note: Meals on Wheels America is a national organization with about 5,000 members, most are local community-based senior meal programs. To join, individuals or meal programs pay a membership fee. It is the oldest and largest organization dedicated to addressing the nutritional needs of senior citizens.

Inflammation of the stomach and bowels caused by microbial contamination of foods or beverages.
Life is extraordinarily complex. That’s true whether you’re considering something as seemingly simple as a blade of grass or as complicated as the human body. However, when we consider the the make-up of living things—from atoms to molecules to macromolecules to cells—we can start to see similarities and patterns that help us make sense of this complexity.
In this unit, we begin with a review of atoms and molecules, simplest substances in food and our bodies, then move to cells. An understanding of these are required to appreciate how the human body uses nutrients. The last sections of this unit focus on the digestive system, the site of food processing and nutrient extraction. And while it usually functions as an efficient and coordinated system, we’ll also consider some common ways that it can go awry, resulting in disorders and discomforts of the digestive tract or adverse reactions to certain foods.
Unit Learning Objectives
After completing this unit, you should be able to:
- Understand the basic structure of molecules and that all nutrients are also chemical molecules.
- Define and describe the levels of structural organization of the human body—from atoms and molecules to the whole organism—including the basic characteristics of cells
- Identify and briefly describe the functions of the organs of the gastrointestinal (GI) tract, and discuss the five fundamental activities of digestion, giving an example of each.
- Describe several common disorders and discomforts of the GI tract, including their causes, symptoms, and approaches to treatment.
- Describe food intolerances, food allergies, and celiac disease, including the different causes, symptoms, and treatments for each condition.
