Study Notes
Nutrition and Health
- Nutrition is the science that studies food and how the body uses food.
- Nutrients are substances in food that are essential for life.
- Essential nutrients are nutrients that the body cannot make or cannot make in sufficient amounts so we must get them from food.
- Six Classes of Nutrients: carbohydrates, fats (lipids), proteins, vitamins, minerals, and water
- Carbohydrates, fats, and proteins provide energy.
- Vitamins and minerals help regulate body processes.
- Water is essential for all life processes.
- Nutrient density is a measure of the amount of nutrients in a food relative to its calorie content.
- The United States was historically referred to as the “melting pot.”
- Dietary-social history is a way to understand how culture influences eating habits.
- Malnutrition is a state of poor health due to an imbalance of nutrients in the diet.
- Deficiency diseases occur when the body lacks an essential nutrient.
- Good nutrition can help prevent disease and promote overall health.
- The six classes of nutrients work together to keep the body healthy.
-
Well-nourished people generally have:
- Healthy weight
- Energy levels
- Clear skin
- Healthy hair
- Strong nails
- Strong bones
-
Symptoms of Malnutrition:
- Fatigue
- Weakness
- Hair loss
- Skin problems
- Poor wound healing
- Clinical examination is a part of a nutrition assessment and includes observing physical characteristics.
- Anthropometric measurements include height, weight, and body composition measurements.
- Biochemical tests measure the levels of nutrients in the blood, urine, or other body fluids.
- Nutrition assessment is a process of determining nutritional status.
- A food diary is a record of everything a person eats and drinks over a period of time.
- A 24-hour recall is a verbal report of everything a person ate and drank in the past day.
- A dietitian is a healthcare professional who is an expert in nutrition.
Specific Nutrient Information
- Proteins are essential for building and repairing body tissues.
- Fats are the highest calorie-value nutrient.
- Vitamins are organic substances necessary for life.
- Minerals are inorganic substances essential for life.
- Water is a major constituent of all living cells.
Body Processes and Wellness
- Circulation is the process by which blood is moved throughout the body.
- Respiration is breathing.
- Digestion is the process by which food is broken down into smaller molecules that can be absorbed.
- Elimination is the process by which waste products are removed from the body.
- Wellness is a state of optimal health and well-being.
Sodium and Potassium
- Sodium is a mineral that is found in many processed foods and can contribute to high blood pressure when consumed in excess.
- Potassium is a mineral found in fruits and vegetables that can help lower blood pressure when consumed in sufficient amounts.
-
Recommendations for Sodium and Potassium
- Consume less than 2,300 mg of sodium per day (approximately 1 teaspoon of salt).
- Choose and prepare foods with little salt.
- Consume potassium-rich foods, such as fruits and vegetables.
Alcohol
- Alcoholic beverages supply calories but few essential nutrients.
-
Key Recommendations for Alcohol Consumption:
- Those who choose to drink alcoholic beverages should do so sensibly and in moderation, defined as the consumption of up to one drink per day for women and up to two drinks per day for men.
- Alcoholic beverages should not be consumed by some individuals, including those who cannot restrict their alcohol intake, women of childbearing age who may become pregnant, pregnant and lactating women, children and adolescents, individuals taking medications that can interact with alcohol, and those with specific medical conditions.
Carbohydrates, Fiber, and Dental Caries
- Carbohydrate intakes of children need special considerations with regard to obtaining sufficient amounts of fiber, avoiding excessive amounts of calories from added sugars, and prevention of dental caries.
The Food Guide Pyramid
- The Food Guide Pyramid is a visual guide that helps people make healthy food choices from the five food groups.
- The largest section of MyPyramid is made up of grains—the bread, cereal, rice, and pasta group.
- At least half of the servings of grains should be whole grains, which provide dietary fiber, B vitamins, iron, and magnesium.
Nutritional Labeling
- The Nutrition Labeling and Education Act (NLEA) of 1900 made nutrition labeling mandatory for nearly all processed foods.
- Nutrition Facts labels provide information about the calorie content, fat content, and other nutrients per serving size of a food.
