Topic 1: Introduction
Lesson 1: A Sampling of Food Topics
Video 1
- Science is all about observations and conclusions.
- Food is the only raw material that goes into our body so our brain must be built to what
goes in our mouth
- Most chemicals we are exposed to are natural
Video 2
- Apples weren’t found in the tree of “fruit of knowledge”, but pomegranates were!
- Pomegranates contain compounds called aromatase inhibitors
- Anti-cancer properties
- Studies show if you take cultured breast cancer cells, douse them with
pomegranate juice, they will multiply juice less quickly
- BUT; you cannot assume that pom. Juice has any impacts on humans
- That’s why pom. Is advertised to be a super / miracle fruit
- “Cherry-picking data”
- Another example: dried apricots in Himalayan mountains
- Contain beta-carotene; an antioxidant
- Claim to have impressive longevity because of eating dried apricots
- Correlation is not causation!! → cherry picking data to make false
associations
- Apricot pits have laetrile which is a bogus cancer remedy but at one
time, it was very popular to “fight” cancer
Video 3 (Flax and Cholesterol and Oatbran)
- Flax is good for the intestines (laxative effect) FLAXATIVE EFFECT LOL :P
- 1. Omega-3 fats → wonder product present in fish (fish > flax seeds)
- Reduction in risk of cardiac arrhythmia
- 2. Lignans (phytoestrogens or plant based estrogen) → beneficial estrogen like
properties → good/bad depending on dosage
- Breast cancer effect for pre-menopausal overweight women → eat flax
seeds to reduce natural estrogen (block estrogen receptors) Studies
show that intake of flax seeds because of lignan reduces risk of breast

cancer bc some breast cancer is stimulated by overproduction of
estrogen
- 3. Insoluble Fiber (indigestible component of food - passes through colon where
bacteria can manipulate, break it down, absorbed/excreted, laxative effect) →
speeding substances through gut and regulating
- 4. Soluble Fiber → reduces cholesterol
- Omega-3 Eggs
- Linked with heart disease → yolk contains 300 mg cholesterol
- Feeding flax seeds to chickens to increase omega-3 fats (but not enough to
work! - just eat flax seeds)
- Donuts
- Use trans fats because they are stable and oil does not break down easily --
raises cholesterol levels
- Oat bran - outer layer of oat grain lowers cholesterol levels (used to be used to feed
horses)
- Very people do not ask the right questions → how much oat bran do you need to
eat to have an effect + how are we exposed to it (eat, inhale, etc.)
- Active ingredient = soluble fiber Beta Glucan → need 3g a day to lower
cholesterol = cup of cooked oat bran (3-5 muffins or 1.5 cup oatmeal)
Video 4
- Fit for life is a BS book!
- Enzymes are protein molecules composed of amino acids
- Biological catalysts (our body can make them ourselves)
- Processed foods are not toxic
- Book is going overboard!
- Book said that sliced white bread are evil
- Whole grain is healthier because more fiber
- But sliced white bread is not toxic
- Yes, does have preservatives otherwise because it will be moldy
- Preserve is calcium propionate to prevent mold and fungi
- Calcium propionate is already in our human body; also in
our sweat!
- We excrete preservatives
- Baguette goes hard quickly because no preservatives
- Vs. french men carry baguette home under the arm
because natural propionate
- French men: coronary artery disease for time higher in NA than in France
- Why? French eating lots of croissants and cheese and goose liver…
- So why do they have fewer heart attacks?
