Every day, we make food choices. Preventative nutrition is now the main focus.
Texas is #10 fattest State, while Mississippi is #1
In general, a chronic disease progresses slowly or with little change and lasts a long time.
An acute disease develops quickly, produces sharp symptoms, and runs a short course.
On average, for humans, for every decade, the average weight gain is 6-10 lbs. per decade.
If the number of calories ingested exceeds the number of calories expended, you will gain weight.
If the number of calories ingested is less than the number of calories you use, you will lose weight.
The science of foods and the nutrients and other substances they contain; their actions within the body (including ingestion, digestion, absorption, transport, metabolism, and excretion). A broader definition includes the social, economic, cultural, and psychological implications of food and eating.
Foods are products derived from plants or animals that can be taken into the body to yield energy and nutrients for the maintenance of life and the growth and repair of tissues.
The foods and beverages a person eats and drinks.
Food choices are made daily based on 10 identifiable reasons.
1. Personal Preference - taste
2. Habit
3. Ethnic Heritage or Tradition
4. Social Interactions
5. Availability, convenience, and economy
6. Positive & Negative Association
7. Emotional Comfort
8. Values (religious beliefs)
9. Body Weight & Image
10. Nutrition and Health Benefits
In Chemistry, a substance or molecule containing carbon-carbon bonds or carbon-hydrogen bonds. In Agriculture, growing crops and raising livestock according to USDA standards
Not containing carbon or pertaining to living things.
Latin: in = not
Carbohydrate, Fat and Protein because they are required by the body in relatively large amounts (many grams daily)
Vitamins and Minerals required in small amounts (milligrams or micrograms daily)
Nutrients a person must obtain from food because the body cannot make them for itself in sufficient quantity to meet physiological needs; also called indispensable nutrients. About 40 nutrients are currently know to be essential for human beings.
Essential Nutrients
Carbohydrates, Lipids (fats), Proteins, Vitamins
Organic nutrients
Minerals and Water
Inorganic nutrients
Like other scientists, nutrition scientists use this unit of measure.
kcal - Kilocalorie
One kcalorie or Kcal is the amount of heat necessary to raise the temperature of 1 kilogram (kg) of water 1 degree.
Calculate the energy available from food.
Carbohydrate = 4 kcal/g
Fat = 9 kcal/g
Protein = 4 kcal/g
Alcohol = 7 kcal/g
Reactions in which small molecules are put together to build larger ones. Anabolic reactions require energy.
Reactions in which large molecules are broken down to smaller ones. Catabolic reactions release energy.
The sum total of all the chemical reactions that go on in living cells. Energy metabolism includes all the reactions by which the body obtains and expends the energy from food.
Scientists first understood vitamins in 1912
A set of nutrient intake values for healthy peole in the US and Canada. These values are used for planning and assessing diets and include:

Risk Factor
Leading cause of death in the US
Heart Disease
Leading factor contributing to death in the US
Cigarette Smoking
Similar to the Estimated Average Requirement, (EAR), this represents the average dietary energy intake (kcalories per day) that will maintain energy balance in a healthy person of a given age, gender, weight, height, and physical activity level.
Estimated Energy Requirement (EER)
