Study of food in relation to health

Nutrition

Is the science that links foods to health and disease

Nutrition

Food and drink regularly consumed

Diet

Kind and amount of food prescribed for a special reason

Diet

Use of diet in the management of a disease

Diet therapy

Maximum well-being

Wellness

All the characteristics that make a person strong, confident and able to function well with family, friends and others

Wellness

The goal of one who strives towards realizing his/her fullest potential physically, mentally, emotionally, spiritually and socialy

Wellness

A range of states with physical, mental, emotional, social and spiritual components

Health

Freedom from physical disease, mental disturbance, emotional distress, spiritual discontent, social maladjustment

Minimum health

2 drives influencing our desire to eat

Hunger


Appetite

Physiologic (internal) drive to find and eat food

Hunger

Mostly regulated by innate cues to eating

Hunger

Primary (psychological) influences that encourage us to find and eat food, often in absence of obvious hunger

Appetite

Is the state in which there is no longer a desire to eat

Satiety

Feeding center

Hypothalamus/satiety center

The science of food and the nutrients and other substances they contain and of their ingestion, digestion, absorption, transport, metabolism, interaction, storage and excretion

Nutrition

Any substance, organic or inorganic, which when taken into the mouth, will provide energy, build and repair body tissues and/or regulate body processes

Food

Chemical component needed by the body for one or more functions

Nutrients

3 functions of nutrients

1. Supply energy


2. Build and repair body tissues


3. Regulate body processes

Energy is expressed in

kilocalories (kcal)

Provide health benefits beyond basic nutrition by altering one or more physiological processes

Functional foods

Compounds in plants that confer color, taste and other characteristics

Phytochemicals

Compounds that protect other compounds from damaging reactions involving oxygen by themselves reacting with oxygen

Antioxidants

Structural parts of plants which can't digested by human enzyme but maybe digested by bacteria in the digestive tract

Fiber

4 beyond the nutrients in foods

1. Functional foods


2. Phytochemicals


3. Antioxidants


4. Fiber

6 categories of nutrients

1. Carbohydrates


2. Proteins


3. Fats (lipids)


4. Vitamins


5. Minerals


6. Water

Chemical substances in food that consist of a single sugar molecule or multiple of sugar molecules in various forms

Carbohydrates

Chemical substances in foods that are made up of chains of amino acids

Proteins

Components of foods that are soluble in fat but not in water

Fats (lipids)

Chemical substances in foods that perform specific functions in the body

Vitamins

Simple, inorganic substances that don't contain carbon atom

Minerals

Acts as a solvent, lubricant, transport medium and medium for temperature regulation and chemical processes

Water

2 classifications of nutrients

Macronutrients


Micronutrients

4 macronutrients

Carbohydrates


Protein


Fats


Water

2 micronutrients

Vitamins


Minerals

2 vitamins

Fat soluble (A, D, E, K)


Water-soluble (B, C)

2 minerals

Major minerals (Mg, Na, Ca, K, P, Cl, S)


Trace minerals

Chew food, perceive taste, moisten food, lubricate food with mucus, release some amylase & lipase, initiate swallowing reflex

Mouth and salivary glands

Move food to stomach by peristaltic waves

Esophagus

Store, mix, dissolve and continue digestion

Stomach

2 acids released by the stomach

Lipase and pepsin

Produce bile to aid fat digestion and absorption

Liver

Store, concentrate and later release bile into the small intestine

Gallbladder

Secretes sodium bicarbonate and enzymes

Pancreas

4 enzymes released by pancreas

Amylase


Lipase


Trypsin


Chymotrypsin

Digest and absorb most substances using enzymes made by the pancreas and small intestinal cells

Small intestine

Synthesize vitamins and short chain fatty acids and form feces

Large intestine

Hold feces and expel via the anus

Rectum

3 major sites of nutrient absorption

Stomach


Small intestine


Large intestine

2 nutrients absorbed in stomach

Alcohol (20%)


Water (minor amount)

Nutrients absorbed in small intestine

Ca, Mg, Fe & others


Glucose, amino acids, fats, vitamins, water, alcohol, bile acids

Nutrients absorbed in large intestine

Na, K, some fatty acids, gases


Water (10-30%)

Where is insulin released?

Pancreas

Where is glucagon released?

Pancreas

Where is epinephrine and norepinephrine released?

Adrenal glands

Where is growth hormone released?

Pituitary gland

Where is thyroid hormone released?

Thyroid gland

Nutrient intake amount sufficient to meet the needs of 97% of the individuals in a specific life stage

RENI (Recommended Energy & Nutrient Intakes) / Recommended Dietary Allowance

Nutrient intake amount set for any nutrient for which insufficient research is available to establish an RDA

Adequate Intake (AI)

Estimate the energy (kcal) intake needed to match the energy use of an average person in a specific life stage

EER (Estimated Energy Requirement)

Generic standards used as a rough guide to compare the nutrient intake of a food to approximate human needs

DV (Daily Value)

The most important nutrient

Water

A basic need of humans

Food

All essential nutrients, fiber and energy are provided

Adequacy

Acute malnutrition example

Underweight

Chronic malnutrition example

Stunting

Providing foods in proportion to one another and to body needs

Balance

Management of the amount of energy

Caloric control

Measure of the nutrients in food relative to the energy it provides

Nutrient density

Consumption of a wide selection of foods within and among the major food groups

Variety

Provision of enough, but not too much of a substance

Moderation

6 nutritious diet
