Refer to ppt notes from Day 1
• If we can get a perso’s genetic material we can know more
Scientific Research
• Who provided sponsorship, depends on who favors it and any chance of biased
• Placebo and drug who should know
• Media and Social Media- more focus on small study that shows fireworks? For eg
somebody losing healthy weight 1-2lbs per week or 20 lbs in a week (unhealthy)
• Credentials of a person
4 types
• Case studies- Within an individual
• Epidemiological studies – Cause and effect, looking at populations
Corelation- Looking at the chemicals and the food- resveratrol in red grapes lead to
lower heart diseases not red wine
Cohort- monitoring over time
More and more kids with lip ties and tongues
Correlation- more folic acid- lip ties or tongues and monitoring the intake of folic acid
and looking at effects
• Intervention study
- More people the better
- With an experimental group and a control group- one group given actual one and
the other one is given placebo
• Lab Studies
- Animals are used
Other ways nutrition is used
- Chemical analysis of food
- Clinical records
- Look at outcomes in past – Women malnourished in certain trimester could lead to
certain diseases
- The baby inside learns to adapt to no food and can lead to obesity later in life

Human Nutrition
- Food- We eat food, an acceptable substance and has physical and chemical
properties, nutrients
- Food should be enjoyable and sometimes craving takes over
- Nutrition- food, and human behavior
- What the purpose of carbs, proteins, fats and hat’s their importance in body
- Diet – everybody is technically on a diet
- Nutrients- keeps the body functioning
- Proteins and functions and other macromolecules
Human body and its food
- Every single food is organic- it means it contains carbon
- Water and minerals are not organic
Important Nutrient terms
- Essential nutrients- get from food, amino acids, Vitamins and minerals
- Non- nutrients- whole food helps more than capsules of the same thing
- Elemental Diet- As soon as the intestinal and stomach muscles stop it can lead to
issues- keep them moving
- In situations where we a’t use those muscles we use tube feed (still use the gut a
little bit)
- TPN- like an IV for people on life support etc.
- Dietary supplements liquid absorbs better than powder and pills
- Nutraceutical- Food products in pill form
Calorie
- calories every day to keep you alive
- Its energy
- If raise the temp by 1 degree Celsius for 1 g of water
- Fats provide us with more energy- we need to limit them as they are dense
- Alcohol is not a nutrient but provides fats and gets stored
- Carbs- 4cal/g
- Fats- 9cal/g

Document Summary
If we can get a perso(cid:374)"s genetic material we can know more. For eg somebody losing healthy weight 1-2lbs per week or 20 lbs in a week (unhealthy: credentials of a person, case studies- within an individual, epidemiological studies cause and effect, looking at populations. Corelation- looking at the chemicals and the food- resveratrol in red grapes lead to lower heart diseases not red wine. More and more kids with lip ties and tongues. Correlation- more folic acid- lip ties or tongues and monitoring the intake of folic acid and looking at effects. With an experimental group and a control group- one group given actual one and the other one is given placebo. Look at outcomes in past women malnourished in certain trimester could lead to certain diseases. The baby inside learns to adapt to no food and can lead to obesity later in life.
