With chloride and potassium (electrolytes) maintain cells normal fluid balance and acid-base balance in body. also crtitical to nerve impluse transmission.

Deficiency: Muscle Cramps, mental apathy, loss of apetite

Toxicity: Hypertension

Food Sources: Salt, soy sauce, processed foods

2

Major Mineral: Chloride

Part of hydrochloric acid found in stomach and necessary for proper digestion.

Deficiency: Growth failure in children; muscle cramps, mental apathy, loss of appetite, can cause death

Toxicity: normally harmles (the gas is poison), can cause vomiting

Food sources: Salt Soy sauce, unprocessed foods, & processed foods

3

Major Mineral: Potassium

Facilitates reactions, including making protein, fluid and electrolyte balance, support cell integrity, transmission of nerve impulses, and contraction of muscles including heart.

Deficiencies dehydration, muscular weakness, paralysis, and confusion, can cause death.

Toxicity: muscular weakness, triggers vomiting, if given into a vein, can stop heart.

Food Sources: all whole foods, meats, milk, fruits, veggies, grains legumes

4

Major mineral: Calcium

Principal mineral of bone and teeth. Acts in normal muscle contraction and relaxation, nerve functioning, blood clotting, blood pressure, and immune defenses.

Deficiency: Stunted growth in children; adult bone loss (osteoporosis)

Toxicity: Constipation, urinary stone formation and kidney dysfunction; interference with absorption of other minerals

Food Source: Milk and milk products, oysters, small fish, tofu, green, legumes

5

Major Mineral: Phosphorus

Important in cells genetic material, in cell membranes as phospholipids, in energy transfer, and in buffering systems.

Deficiency: unknown

Toxicity: may cause calcium excretion

Food sources: all animal tissues

6

Major Mineral: Magnesium

Bone mineralization; building of protein, enzyme action, normal muscle contraction, transmission of nerve impulses, and maintenance of teeth.

Deficiency: Weakness, confusion, if extreme: convulsions, bizarre movements (esp of eyes and face) hallucination, difficulty swallowing. IN children: growth failure.

Toxicity: Large doses taken in laxative form Epsom, diarrhea

Food Sources: Nuts, Legumes, whole grains, dark green veggies, seafoods, chocolate, cocoa

7

Major Mineral: Sulfur

A component of certain amino acids; part of vitamins Biotin and thiamin, and hormone insulin; combines with toxic substances to form harmless compounds; stabilizes protein shape

deficiency: none known

toxicity: only if eaten in excess , depresses growth ( in animals)

Food Sources: all protein-containing foods

8

What are the 6 classes of nutrients?

Water, Carbs, fats, proteins, vitamins, and minerals

9

How is energy measured?

In kCalories

10

Which nutrients contain carbon(being organic)?

Carbs, fats, proteins, and vitamins

11

What are six characteristics of a nutritious diet?

adequacy, balance, kcalorie control, nutrient density, moderation, and variety.

12

What is the Gastrointestinal Tract (GI)?

a flexible muscular tube extending from the mouth to the anus.

13

What are the 2 essential fatty acids?

Linoleic Acid (Omega- 6), found in seeds of plants, nuts, veg oil and

Linolenic Acid (Omega - 3) found in fish oils

they are polyunsaturated

14

Phospholipids

they act as emulsifiers, helping to keep other fats in solution in the watery blood and body fluids.

15

Sterols

large complex molecules consisting of interconnected rings of carbon;

One of the 3 main classes of Lipids, incudles choloesterol, VItamin D, and sex hormones

Animal derived foods contain significant amounts of cholesterol (meats, egg, fish, dairy) Organ meats, liver & Kidneys & eggs are the highest.

It is non-essential, the body can make cholesterol

16

Bile

a compound made by liver from cholesterol and stored in the gall bladder. Bile prepares fat for digestion.

17

Trans-fatty acid

Raises LDL and Lowers HDL and produces inflammation

found in fast food, processed food, chips, cookies

18

What minerals may vegans lack?

Iron and zinc

19

What vitamin may vegetartians lack?

B12 bc it's from animals only. also Vitamin D & riboflavin if they are vegan and don't drink milk, don't go outside or don't eat leafy greens

20

Lipoprotein Lipase

an enzyme that promotes fat storage in fat cells and muscle cells

21

Leptin

a hormone produced by fat cells under direction of ob gene, It decreases appetite and increases energy expenditure. In obese kids, this hormone is is barely detected.

22

Grehlin

acts opposite of leptin; a hormone produced by stomach cells and signals to hypothalamus of the brain to stimulate appetite and food intake.

23

Set point Theory

theory that the body tends to maintain a certain weight by means of its own internal control.

24

Vitamins

essential nonkcaloric nutrients that are needed in trace amounts in diet to help facilitate body processes.

25

B Vitamins

They do not give energy, but help to burn that fuel. 8 b vitamins. each part of an enzyme helper, called coenzyme.

26

Active form of B Vitamins

Thiamin riboflavin, niacin, pantothenic acid, and biotin- these participate in the release of energy from carbs, fat and protein

27

B6

coenzyme, that metabolize amino acids

28

Folate

making of new cells

29

B12

depends on folate, making new cells

30
