system•potatoes, bananas, beans, seeds, nuts, red meat, poultry, fish, eggs, spinach,
B12 •producing antibodies, helps folacin function, maintenance of nerve tissue•fish, red meat, poultry, milk, cheese, and eggs. It's also added to some breakfast cereals.
Folacin •synthesize DNA•cell division•Liver, dried beans and other legumes, green leafy vegetables, asparagus, and orange juice
Small amounts needed for good health Stored in liver Will not be lost in preparation Megadoses can lead to health problems
and can be toxic
FAT SOLUBLE
VITAMIN A •vital to good vision•prevents night blindness•severe deficiency causes blindness•necessary for healthy skin, hair growth•keeps mucous membranes healthy•milk, eggs, liver, carrots, sweet potatoes, pumpkin, and kale, orange fruits- cantaloupe, apricots, peaches, papayas, and mangos.
VITAMIN D Only one manufactured by the body
•found in foods and obtained from the sun•helps bones use the mineral calcium to build strong bones•prevents rickets•your body manufactures it when you get sunlight on your skin!
FAT SOLUBLE
VITAMIN E •helps breakdown polyunsaturated fats•antioxidant, protecting blood cell membranes from overexposure to oxygen•vegetable oils, nuts, and green leafy vegetables. Avocados, and whole grains
VITAMIN K •essential for clotting of blood•found in foods and manufactured by Vitamin K producing bacteria in the small intestines•Vegetables, broccoli, lettuce, green beans
FAT SOLUBLE
MEGADOSES OF VITAMINS Does not improve exercise
performance or potential to sustain intense physical training
Many products will falsely claim that megadoses can improve health (review some of the claims).
- vitamin c: cure common cold - vitamin B12: provides extra
energy Claims are based on the benefits
seen in vitamin therapy for people who are deficient. The myth is based on the erroneous logic that if a little is good more is better.

Converting energy from food, cell repair, building strong bones, teeth and muscles and regulating body temperature.
Green leafy vegetables, wholegrains and nuts, black beans
MACROMINERALS
MACROMINERALS Phosphorus
RDA: 1250 mg per day Overdose: lead to calcium being deposited on the soft
tissues and reduced absorption of the other macrominerals
Deficiency: include anemia, confusion, increased risk of infection, weakness
work with calcium and support the growth of strong, healthy bones and teeth. On top of this it also helps activate the B complex vitamins, assists in the construction of healthy cell membranes, helps create deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) and supports proper kidney function.
Beef fillet steak, brazil nuts, cheddar cheese, chicken, milk
SulfurRDA: none setOverdose: no upper limitDeficiency: arthritis, circulatory problems,
inflammation, nerve disorders and skin problems
The main role of sulfur is to treat joint and skin conditions.
Assist in production of keratin (a protein that promotes healthy hair, nails and skin)
Brazil nuts, cheddar cheese, chicken, egg, spinach
MACROMINERALS
PotassiumRDA: 4.7 g per dayOverdose: diarrhea, nausea, stomach pain,
ulcersDeficiency: confusion, dry skin, muscle
cramps, thirsthelping your body break down
carbohydrates and protein, promoting muscle growth, regulating blood pressure and supporting nerve transmissions
Bananas, dried apricots, fillet steak, scallops, spinach
MACROMINERALS
SODIUM
RDA: >2400 mg per day Overdose: fluid retention, high blood pressure, heart
disease, kidney Deficiency: confusion, headaches, lethargy and nausea
Sodium has multiple roles in the body which include helping your body break down carbohydrates and protein, keeping minerals soluble in the blood, keeping your joints flexible, maintaining blood volume, supporting the major organs, supporting muscle contractions and supporting nerve transmissions
Cheddar Cheese , Olives , Salted Butter , Table Salt
ChromiumRDA: 35 mg/day males, 24 mg/day femalesDietary chromium is found in small
concentrations in most foods. A balanced diet that includes meats, whole grains, dairy products, fruits, and vegetables will provide all the chromium you need
Chromium is necessary for normal metabolism and storage of sugar and starch. Chromium is found in a wide variety of foods, so deficiencies are very rare
TRACE MINERALS
TRACE MINERALS Copper
RDA: 890 mcg/day necessary for your body to make connective
tissue, which is needed for strong blood vessels, cartilage and bones, also necessary for some antioxidant reactions to occur, as well as for the metabolism of iron
also necessary for some antioxidant reactions to occur, as well as for the metabolism of iron
Copper deficiency isn't common because it is found in a wide variety of foods
seafood, chicken, nuts, seeds, whole grains, chocolate and legumes.
TRACE MINERALS Fluoride
RDA: 3 mg/daystrong bones and teeth, also can stimulate
bone growthFluoridated water is credited with reducing
the number of cavities in the teeth of children by 50 to 60%.
deficiencies may result in an increased risk of dental cavities and weaker bones
fluoridated water, many brands of toothpaste and foods prepared with fluoridated water.
TRACE MINERALS Iodine
RDA: 150 mcg/day synthesize thyroid hormones that are
necessary for regulating your body's growth, development, metabolism and body temperature
iodized salt,seafood, and in lesser amounts in dairy products, fruits and vegetables. Iodine can be toxic in large amounts (approximately 1,000 mcg per day). Ingesting too much iodine can depress thyroid gland function
deficiency can result in a thyroid condition called goiter
Iron RDA: 11 mg/day males, 15 mg/day females transporting oxygen to cells, cell growth Iron deficiency results in a reduced amount of
oxygen that is delivered to the cells and leads to fatigue and anemia. Not getting enough iron can also negatively affect your immune system. Deficiency can occur from lack of iron in the diet, difficulty absorbing enough iron from the foods you eat, or from chronic blood loss during menstrual periods
toxic in large amounts (over 45 mg/day) red meat, pork, fish and shellfish, poultry, lentils,
beans and soy foods, green leafy vegetables, and raisins.
TRACE MINERALS
TRACE MINERALS Manganese
RDA: 2.2 mg/day males, 1.6 mg/day females
important for production of enzymes and antioxidants that fight free radical damage. Manganese is also necessary for nervous system function
nuts, seeds, legumes and whole grains Manganese deficiency appears to be
extremely rare
TRACE MINERALS Molybdenum
RDA: 43 mcg/day mostly as a component of three enzymes
your body needs to metabolize certain amino acids, produce uric acid and help to break down drugs and toxins
Molybdenum deficiency doesn't occur in humans because it is found in many foods and is needed in such small amounts. Dietary molybdenum is found in the largest amounts in peas, lentils and other legumes, however it is also found in fruits, vegetables and many animal foods
TRACE MINERALS Selenium
RDA: 55 mcg/day combines with proteins to make antioxidants that
help protect the cells in your body from free radical damage. Selenium is also essential for normal thyroid function
plant-based foods, such as whole grains and nuts, as well as most animal-based foods
Selenium deficiency is rare in developed countries; however, a selenium deficiency may contribute to heart disease, thyroid dysfunction and a weakened immune system
ANTIOXIDANT
are the body's major defense against free radicals. They fight free radicals by supplying them the electron they lack, and thus neutralize them.
Vitamin C, vitamin E, and A, grape seed extract and others are potent antioxidants
ANTIOXIDANT ROLE OF VITAMINS
Chemical reactions often result in formation intermediate products.
Reactive intermediates are highly unstable.
A free radical is a highly reactive intermediate species that has an unpaired electron. A free radical might look like this.
Makes up about 60% of your body weight
Flushes toxins out of vital organs Carries nutrients to your cells Lack of water can lead to dehydration
WATER
You lose water through your breath, perspiration, urine and bowel movements
Must replenish its water supply by consuming beverages and foods that contain water
Men is roughly 13 cups Women is roughly 9 cups On average, food provides about 20
percent of total water intake
HOW MUCH WATER?
Exercise1.5 to 2.5 cups of water for short bouts of
exerciseLonger duration events will need more,
depending on how much you sweat during exercise
Sports drinks are good for long, intense activities because they replenish sodium as well
Continue replacing fluids after activity is over
FACTORS AFFECTING WATER NEEDS
Environment Hot or humid weather can make you sweat
and requires additional intake of fluid. Heated indoor air also can cause your skin
to lose moisture during wintertime. Altitudes greater than 8,200 feet may
trigger increased urination and more rapid breathing, which use up more of your fluid reserves
FACTORS AFFECTING WATER NEEDS
IllnessFever, vomiting, diarrhea can cause
increased fluid lossMay need increased fluid intake if you
develop certain conditions, including bladder infections or urinary tract stones
Pregnancy/Breast FeedingNeed additional fluids to stay hydratedPregnant women drink about 10 cupsWomen who breast-feed consume about 13
cups
FACTORS AFFECTING WATER NEEDS
WATER Water is the most important nutrient in
our diet. We would die much quicker without water than we would without food. Survival Rule of 3s: 3 minutes-air, 3 days-water, 3 weeks-food, 3 months-companionship.
DIETARY SUPPLEMENT provide nutrients, such as vitamins,
minerals, fiber, fatty acids, or amino acids, that may be missing or may not be consumed in sufficient quantities in a person's diet
Not necessary if diet is healthy Multivitamins are safe (100% RDA) Benefits those with marginal intake Supplementation above the RDA may be
toxic and 40 years of research does NOT support it.
SUPPLEMENTS The current consensus is that a
balanced nutritious diet can provide all of the vitamins that a person needs. If a person wanted to be sure their diet is adequate it is safe to take a multivitamin each day as long as the vitamin does not provide over 100% of the RDA values.
