6 Classes of Nutrients:
Substances obtained from food and used in the body to promote growth maintenance and repair.
A nutrient that MUST be obtained from food because the body CANNOT make it for itself.
A nutrient that can be obtained from other places because the body makes it.
Energy yielding nutrients (3):
These do NOT yield energy once broken down in the body, but do perform other tasks such as maintenance and repair:
The capacity to do work, such as moving or heating something.
The unit used to measure energy.
Carbohydrates contain __ calories per gram.
Proteins contain __ calories per gram.
Fats contain __ calories per gram.
Alcohol contains __ calories per gram.
The body uses energy from carbohydrates, fats, and proteins to do work or generate heat.
Organic, or carbon containing essential nutrients that are vital to life but needed only in relatively minute amounts.
Inorganic compounds, some of which are essential nutrients.
Vitamins and minerals do not supply energy, or calories, instead they regulate the release of energy and other aspects of METABOLISM.
Collective term for all of the chemical and physical reactions occurring in living cells, including the reactions by which the body obtains and uses energy from foods.
Water soluble vitamins:
B & C
Fat soluble vitamins:
A, D, E & K
Provides the medium for life processes.
Water carries materials to and from cells and provides the warm nutrient rich bath in which cells thrive.
When energy yielding nutrients release energy, they break down into water and other simple compounds, without water you could live only a few days.
How to calculate the caloric value:
If you now the number of grams of carbohydrates, fats and proteins in a food you can calculate the number of calories in it.
Add the total together to obtain the number of calories.
- Simply multiply the carb grams by 4
- multiply fat grams by 9
- multiply protein grams by 4
How to calculate the percentage:
The percentage of your total energy intake from carbohydrate, fat and protein can then be determined by dividing the number of calories from each energy nutrient by the total calories and then multiplying your answer by 100 to get the percentage.
45 grams of carb x 4 calories =180 calories
39 grams of fat x 9 calories = 351 calories
27 grams of protein x 4 calories = 108 calories
TOTAL 639 calories
calories from carb =45 x 4 cal/gram/639 = 0.281 x 100 = 28%
calories from fat = 39 x 9 cal/gram/639 = 0.548 x 100 = 55%
calories from protein = 27 x 4 cal/gram/639 = 0.168 x 100 = 17%
5 Leading Causes of Death that have been linked to diet:
- Heart disease
3 deaths associated with excessive alcohol consumption:
- Liver Disease
Any condition caused by an excess, deficiency or imbalance of calories or nutrients.
Calorie or nutrient over consumption severe enough to cause disease or increased risk of disease a form of malnutrition.
Deficiency diseases in American have been virtually eliminated due to the abundance of food and practice of fortifying food with essential nutrients (adding iodine to salt for example)
A chronic disease characterized by deterioration of body organs as a result of misuse and neglect. Poor eating habits, smoking, lack of exercise and other lifestyle habits often contribute to some diseases.
- Heart disease
Not all diseases are equally influenced by diet. Some may be inherited.
Nutrition Unresponsive (Genetic) Diseases:
- Sickle cell Anemia
- Adult bone loss (osteoporosis)
A number of environmental, behavioral, social and genetic factors work together to determine a person's likelihood of suffering from a degenerative disease.
Positive Lifestyle Elements:
- Avoid excess alcohol
- No smoking
- Maintain a healthy weight
- Exercise regularly
- Sleep 7-8 hours a day
- Eat breakfast
- Eat nutritious regular meals
The key to disease prevention and optimal health is not eating or avoiding a certain food, but rather in creating a lifestyle that includes time for preparing nutritious meals and enjoying regular physical activity.

Healthy People 2010 has two broad goals:
increasing the quality and years of healthy life and by eliminating health discrepancies
The physiological need for food.
The psychological desire to eat, which is often but not always accompanied by hunger.
Our diets are limited by the types and amounts of food available through the food supply, which, in turn, is influenced by many forces.
History have shown that when it comes to health an abundant food supply can be a double edged sword.
Access to many types of foods allows people to choose high fat diets that are rich in meats and other fatty foods, which can contribute to increased rates of heart disease and other problems.
That's one of the reasons why degenerative diseases are sometimes referred to as DISEASE OF AFFLUENCE.
Severe under consumption of calories or nutrients leading to disease or increased susceptibility to disease, a form of malnutrition.
Extremely low income can make it difficult for people to buy enough food to meet their minimum nutritional needs putting them at risk for under nutrition.
Numerous factors influence your food choices including these:
- Hunger, appetite and food habits
- Nutrition knowledge health beliefs, concerns and practices

Additionally the purchase of locally produced foods protects the environment by reducing the use of fossil fuel (for transporting food) and packaging materials.

How can you tell if a nutrition news story is noteworthy and a source of credible nutrition information?
- Study described should be published in a journal that uses experts in the field to review research results called PEER REVIEW
- Be sure report is about recent research
- Are the reported results from an epidemiological study (examine populations to determine food patterns and health status over time) or intervention study(examine the effects of a specific treatment or intervention on a particular group of subjects and compare the results to those of a similar group of people not receiving the treatment)
A group of individuals with characteristics that match those of the group being treated in an intervention study but who receive a sham treatment or no treatment at all.
