Physiology for Nutrition, Health and Fitness
Does what we
Eat,
Think,
Do
really matter?
Important Factors in Health
1) Diet (Nutrition)
2) Mentality and Emotions
3) Physical Activity
4) Toxins (Environment)
5) Spirituality
Materials for the Body
• Carbohydrates
• Lipids
• Proteins
• Minerals
• Vitamins
• Enzymes
Whole Foods
• Unrefined, entire original “item”.
• All original nutrients remain intact.
• Unprocessed, not chemically treated.
e.g.: - whole brown rice (),quinoa- organic vegetables and fruit- raw nuts and seeds
Refined Foods• Heavily processed from original form.
• Most (if not all) original nutrients removed.
• Often chemically treated (in processing and for shelf-life).
e.g.: - white sugar ()- white flour- heavily preserved (packaged) items
What is a Carbohydrate?
Glucose* = monosaccharide, a simple sugar
Lactose* = disaccharide (glucose and galactose)
Sucrose** = disaccharide (glucose and fructose)
Cellulose = polysaccharide (cannot digest)
Starch = polysaccharide (many glucose molecules)
Simple Complex
Maltose* = disaccharide (glucose and glucose)
Refined Whole
- candy - white bread - potato chips
- fruits - whole grains - vegetables
What is Sugar?
Glucose - most important sugar in Human Body!
Sucrose - highly refined, ‘table sugar’ – Avoid!
High Fructose Corn Syrup – Evil!!!
Why?
“But it tastes so good”
Insulin Levels
Rollercoaster ride = Diabetes Mellitus Type II
Advanced Glycation End-products (AGE’s)
Glycoproteins - normal.
If blood glucose chronically elevated, it binds
to proteins non-enzymatically = AGE’s
This is when things start to go wrong!

Many pathways in the body elevate blood glucose but only one lowers it.
Why only one way to lower blood glucose???
Insulin
Why?
Far more Sugar in our Diet now!
Cultural? Social? Conditioning?
Television, Movies, Advertisements
e.g., in 1999 the average American consumed 150lbs of sugar/year.
Taste Test
A B 50% - 50% split!
Coke 85% chose coke!
(Montague, 2005)
Pepsi 50% - 50% split!
Researcher’s Comment
“There are visual images and marketing messages that have insinuated themselves into the nervous system of humans who consume the drink. It is possible that cultural messages perturb taste sensation.”
All Fats are Not Equal!
Omega-3- and 6-Fatty Acids
Hydrogenated Vegetable Oils
Cholesterol (LDL’s and HDL’s)
Trans Fats and Acrylamide
*Dr. Ancel Keys (1958) Ischemic Heart Disease
Virgin Coconut Oil - a saturated fat with medium chain Fatty Acids (MCFA) -extremely heat stable and very beneficial for human physiology.
Polyunsaturated Fats – e.g., canola, soybean, safflower, corn - easily become rancid when exposed to oxygen and produce free radicals in the body.
Unsaturated Oils vs. Saturated Fats
*Olive oil – Still good; best if not heated!
Saint-Onge and Jones (2003)
Eating fat makes you fat and increases your risk of cardiovascular disease - Right?

When blood Glucose is highInsulin is released to makeblood Glucose lower (normal)
Cells in your bodyup-take the glucose
When blood Glucose is lowGlucagon is released to makeblood Glucose higher (normal)
Liver is key site:
Hepatocytes liberate Glucose stores (glycogen) and use fats & proteins to make more glucose

How much Protein?Metabolic Typing
2. High Carbohydrate.
3. Mixed.
1. High Protein.
a) Meat
b) Soy
c) Eggs
d) Quinoa
High in Protein
growth hormone injected, antibiotic loaded,corn fed, poorly treated, sick animals.
trypsin inhibitors, goitrogens, phytic acid,phytoestrogens, haemagglutinin, GM.
Find organic eggs! Nutrient rich!
Complete protein, higher protein content than soy.
One of the best foods to eat to control blood glucose is Fats - the right fats!

There must be a BETTER food structure that this Pyramid?
Why Organic?
1. No growth stimulants, no antibiotics, no artificial fertilizers.
1. No pesticides, irradiation, preservatives, additives, artificial colors or flavors.
3. No Genetically Modified Organisms (GMOs).
4. Primarily Locally Grown, Seasonal food.
5. Higher nutrient and mineral values ( taste).

Suggestions:
Avoid certain “foods”!
- No, not even in moderation! -
Better Alternatives?:
What about artificial additives and flavors?
Question why they are added.
Examine what their effects might be.
Excitotoxins
• MonoSodiumGlutamate (MSG) ‘flavoring’.
• Aspartame artificial ‘sweeter’ (Sucralose)
Substances when ingested in high quantities interfere with nervous transmission.
e.g., interfere with the excitatory neurotransmittersGlutamate and Aspartate.
(“Excitotoxins: The Taste that Kills” by Dr. Russell Blaylock, 1995)
Why is MSG bad for you?!?
Interferes with actions of the Hypothalamus in your brain.

Aspartame - An Intense Source of Excitotoxins
• Made from phenylalanine and aspartate.
• Accounts for ~ 70% of all complaints to FDA.
• Breaks down at room temp into toxic and dangerous ingredients:
1. DKP (di-ketopiperazine). When ingested, converts to a near
duplicate of a powerful brain tumor causing agent.
2. Formaldehyde - embalming fluid.
3. Methanol - extremely dangerous alcohol, causes blindness.
Ingredients Purpose Adverse Effects
Aspartame Sweetener Breaks down to its neurotoxic components phenylalanine, aspartic acid and methyl alcohol. FDA reports consumption associated with headaches, dizziness, loss of balance, mood swings, nausea, memory loss, muscle weakness, blurred vision, fatigue, weakness, skin rashes, joint and musculo-skeletal pain. Also linked rare tumors known as gliomas and lymphomas.
Acesulfame K Sweetener Causes cancer in animals. Breaks down to Acetoacetamide, shown to affect the thyroid gland in rats, rabbits, and dogs. Use with aspartame to cover its bitter taste, however, there are no studies to show if the combination is safe or whether it produces other toxic by-products.
Phosphoric Acid
Acidifier Erodes tooth enamel; leaches calcium from bones. High soda intake children suffer from osteoporosis.
Citric Acid Preservative, Acidifier
Harsh on tooth enamel, but when mixed with potassium or sodium benzoate during storage (esply at raised temperatures), can form benzene, a known carcinogen.
Dangerous Ingredients in Diet Coke
Ingredients Purpose Adverse Effects
Caffeine Flavoring A CNS stimulant, highly addictive, diuretic; can provoke mood changes, lethargy and headache. Ingestion of high levels can cause miscarriage, peptic ulcers and heart ailments. Children consuming caffeine have higher incidences of illness, headaches, sleep problems and iron depletion.
Sodium Benzoate (E211)
Preservatives In acidic solutions (e.g., sodas), benzoates can break down into benzene. Surveys show levels in soft drinks up to 40 times higher than recognized ‘safe’ doses.
Sulphite Ammonia Caramel (E150d)
Coloring Made by heating sugar, ammonia and sulphites. Ammonia is toxic and caramels made by an ammonia process may damage genes, slow growth, cause enlargement of the intestines and kidneys and destroy vitamin B. This coloring has never been fully evaluated for its potential toxicity.

Sugar Aspartame
Environmental Toxins
• Not just in what you eat!
• Cosmetics, Personal Hygiene, Perfumes.
• House Cleaning Agents and Solvents.
Harmful Ingredients in Cosmetics!
• Methylisothiazoline (MIT) – extensively used in shampoos. Causes neurological damage (National Institute of Health).
• Phenol Carbolic Acid - found in many lotions and skin creams.
• Parabens – widely used in skin-care products. Mimic estrogen, encourages growth of human breast tumors.
Can cause circulatory collapse, paralysis, convulsions, respiratory failure.
More
• Sodium Lauryl Sulfate - the 'foam-up' of soaps, shampoos, detergents, toothpastes.Breaks skin’s moisture barrier, can become a “nitrosamine”.
Linked to anemia, ↓ blood cell count, liver/kidney damage.
• Toluene - in most synthetic fragrances.
• Propylene Glycol - main ingredient in anti-freeze and used in hydraulic fluids. Dermatitis; kidney/ liver abnormalities
The Information is Out There
1. Question Everything – Don’t blindly accept.
2. Empower yourself by knowing things.Allows us to make well-informed decisions
