GLOBAL NUTRITION

Throughout this course we have been primarily been discussing nutrition in the United States:

A Global View of Nutrition

- Food availability - Food choices - Guidelines - Diet and exercise - Undernutrition - Overnutriton and obesity - Diet and disease risks - Maternal & infant nutrition

Throughout this course we have been primarily been discussing nutrition in the United States:


- Food availability - Food choices - Guidelines - Diet and exercise - Undernutrition - Overnutriton and obesity - Diet and disease risks - Maternal & infant nutrition

Many other parts of the world have similar nutritional patterns, but there are some significant differences.

Concerns

Hunger Uneasy or painful sensation caused by lack of foodUndernutrition / Malnutrition Failure to achieve nutrient requirementsFood insecurity Limited or uncertain availability of nutrients or foodOvernutrition Failure to limit food intake


Groups at risk:

Poor - Can not afford foodIsolated - Lack access to food resourcesInadequately housed – Lack access to food storage & preparationChildren – Dependent on family circumstances Hunger, malnutrition affect school performanceElderly - Economic difficulties, Physical ailments



More than 48 million Americans (nearly one in six) are food insecure.

About one-third of those had very low food security in which the food intake was reduced and their normaleating patterns were disrupted.

Food insecurity exists in every county in America, ranging from a low of 5% in Steele County, ND to a high of 38% in Wilcox County, AL.


In the United States, more than 12 million children live in households which are food insecure:

More then 3 million don’t have enough to eat and are deficient in calories and most nutrients

More than 9 million consume enough calories but are deficient in specific nutrients such as proteins, complex carbohydrates, vitamins, or minerals.

A Global View of NutritionAt the same time:

Two-thirds of adults in the U.S. are overweight (BMI > 25) and nearly one third are obese (BMI > 30)

One-sixth of U.S. children aged 6 to 19 are overweight or obese.

300,000 deaths each year are due to obesity


We’ve already discussed the nutritional guidelines of USDA and DHHS to help develop healthy diets.


In the United States, a number of programs attempt to help meet the nutritional needs of children:

At the federal level these are coordinated by the USDAFood and Nutrition Services Program

- Supplemental Nutrition Assistance Programs (food stamps) - Women, Infants, and Children (WIC) - School breakfast and lunch programs


In the United States, a number of programs attempt to help meet the nutritional needs of children:

Many states and communities also provide assistance:

- Minnesota Food Assistance Program

- Wisconsin Emergency Food Assistance Program - Local Food banks

Worldwide, nutritional programs are provided through such agencies as

- United Nations

- International Nutrition Foundation

- World Health Organization

- Cooperative for Assistance & Relief Everywhere

Most nations also have their own agencies

Worldwide, more than 20,000,000 children under the age of five suffer from severe undernourishmentleading to diseases we have alreadydiscussed such as rickets (vitamin D deficiency) scurvy (vitamin C deficiency) beriberi (thiamine deficiency) pelagra (niacin deficiency) kwashiorkir or marasmus (protein & calorie deficiency)


Worldwide, more than 20,000,000 children under the age of five suffer from severe undernourishmentleading to diseases we have alreadydiscussed such as rickets (vitamin D deficiency) scurvy (vitamin C deficiency) beriberi (thiamine deficiency) pelagra (niacin deficiency) kwashiorkir or marasmus (protein & calorie deficiency)


Nearly 6,000,000 children die from undernourishment each year – half of all child deaths.

Vitamin A deficiency is the leading cause of preventable blindnessDeficiencies of calcium, potassium, biotin, zinc, or vitamin E lead to growth retardationDeficiencies of iron, riboflavin, folic acid, or vitamins B6 or B12 lead to anemia and other problemsVitamin K deficiencies lead to bleeding problemsIodine deficiencies lead to thyroid problems and goiter



Factors that contribute to hunger and malnutrition:1. The world food equation correlates three things - Economic development - Employment - Food consumption

While economic development is generally a good thing for a country, the increased employment leads to higher standards of living which leads to increased food consumption.

1. The world food equation correlates three things - Economic development - Employment - Food consumption

Economic development also changes the patterns of food production & consumption: Smaller farms larger farms Hand / animal farming mechanized farming Crops for food crops for biofuels Fewer whole foods more processed foods

Factors that contribute to hunger and malnutrition

1. The world food equation correlates three things - Economic development - Employment - Food consumption

End result: Food more expensive Food unevenly distributed Fewer foods available Fewer people have access to healthy diets


2. Global climate change leads to Unpredictable growing seasons, which leads to Less food and fewer foods, which lead to Increased cost, which leads to Fewer people have access to healthy diets


3. Overpopulation leads to More people consuming the same amount of food , which leads to Less food available per person and Increased food costs, which leads to Fewer people have access to healthy diets


Population per square kilometer


4. Urbanization leads to Increased transportation costs, which leads to Increased cost, which leads to Fewer people have access to healthy diets


5. Poverty leads to Fewer people can afford to grow food and Fewer people can afford to buy food which leads to Fewer people have access to healthy diets


6. Disease also plays a major role

- Bacteria, viruses, and parasites spread through contaminated food or water cause diarrhea (dysentery) and/or vomiting, preventing absorption of nutrients

- Inflammatory diseases such as Crohn’s disease or ulceritive colitis prevent aborption of nutrients

- Any disease which weakens individuals makes it difficult for them to find food or to eat


7. War and civil unrest leads to Destruction of farmland and Fewer people farming and Uneven distribution of food which leads to Fewer people have access to healthy diets


8. Environmental damage leads to Destruction of farmland which leads to Less food available per person and Increased costs to produce & purchase food which leads to Fewer people have access to healthy diets



Obviously, none of these factors alone cause the problem:

Economic development Climate changes Overpopulation Urbanization Poverty Disease War Environmental damage

Often coexist


Let’s return for a moment to the world food equation correlating Economic development Employment Food consumption

While one result is increased hunger and malnutrition, another result is increased obesity


The take-home message: Just like everything else we have discussed in this class the key to nutitional health is moderation – be food smart: Healthy foods Different types of foods Fewer refined and processed foods Ensure adequate, but not excessive, intake of all nutrients

That’s the last topic in this course so

We will not meet Thursday

Instead, here’s the last quiz :

Quiz #6: Select one of the following countries and list five causes of food insecurity or malnutrition in that country. - Do not list more than 5 causes - Each answer must specify the effect For example: “Poverty” would not be enough, but “Poverty rate is 72%” would be OK - No single answer can be more than eight words

Afghanistan Guatemala Angola Haiti Bolivia Mali Cambodia Peru Ethiopia Sudan
