❏Driving questions
❏What are the macronutrients and micronutrients provided by food?
❏What are essential nutrients?
❏What are enzymes, and how do they work?
❏What are the consequences of a diet lacking sufficient nutrients?
❏The peanut butter project
❏Doctor’s effort to end malnutrition in Africa
❏A nonprofit organization using the American pantry staple to end malnutrition in
Africa
❏What is malnutrition?
❏A medical condition resulting from the lack of essential nutrients in the diet
❏Often, but not always, associated with starvation
❏Malnutrition around the world
❏Number one killer of children around the world
❏More die each year than the number who die from AIDS, tuberculosis, and
malaria combined
❏Most deaths occur in sub-saharan Africa
❏Poverty is endemic
❏Food is scarce most of year
❏Why does lack of food lead to malnutrition?
❏Food contains nutrients
❏Nutrients
❏The chemical building blocks our bodies need to live, grow, and repair
themselves
❏Provide energy
❏Energy is the ability to do work
❏Powers our activities
❏Helps build complex muscles
❏Macronutrients
❏Nutrients that organisms must ingest in large amounts to maintain health
❏Carbohydrates, proteins, lipids (fats)
❏Food provides macronutrients
❏Foods contain mixtures of macronutrients
❏A varied diet must include
❏Vegetables
❏Oils
❏Grains
❏Meat
❏Dairy products
❏Many foods contain all three types of macronutrients
❏The proportion of each one varies in different foods
❏Animal products contain more protein per gram than carbohydrate

Document Summary
Doctor"s effort to end malnutrition in africa. A nonprofit organization using the american pantry staple to end malnutrition in. A medical condition resulting from the lack of essential nutrients in the diet. Often, but not always, associated with starvation. Number one killer of children around the world. More die each year than the number who die from aids, tuberculosis, and malaria combined. The chemical building blocks our bodies need to live, grow, and repair themselves. Energy is the ability to do work. Nutrients that organisms must ingest in large amounts to maintain health. Many foods contain all three types of macronutrients. The proportion of each one varies in different foods. Animal products contain more protein per gram than carbohydrate. Most plant products contain more carbohydrate than protein. Must be broken down into smaller units. Use subunits as building blocks or energy. Use to assemble new proteins that have many different functions in the body.
