THE CHINA STUDY AND PLANT BASED PROTEIN PROTEIN
A
Chris Castiglione
3 THINGS WE ALL AGREE ON
1. Eat Mostly Plants
2. Eat less meat
3. Avoid processed foods
EAT MOSTLY PLANTS

HOW WOULD YOU DESCRIBE THE CHINA STUDY IN ONE MINUTE?
“THE MOST COMPREHENSIVE STUDY ON NUTRITION EVER CONDUCTED”
RESEARCH FROM 6,500 PEOPLE
OVER 20 YEARS
A study of protein

What if I told you that you had a 10,000% higher chance of getting cancer in NYC?

TAKEAWAYS
HOW FOOD GROWS CANCER
The Three Stages of Cancer Growth
1. Seeds
2. Grow
3. Out of Control
1. Initiation (Seeds)
The cancer seeds are known as carcinogens. They enter your body through the everyday harmful chemicals that you let in through air, water and food.
1. Initiation (Seeds)
“[Initiation] is the time required for the chemical carcinogen to be consumed, absorbed into the blood, transported into the cells, changed into its active product, bonded to DNA and passed on to the daughter cells. When the new daughter cells are formed, the process is complete.” [49]
“The entire stage [of initiation] can take place in a short period of time, even minutes.”
2. Promotion (The Seeds Grow)
Just like seeds in the soil, the initial cancer cells will not grow and multiply unless the right conditions are met. The seeds in the soil (for example) need a healthy amount of water, sunlight and other nutrients before they become a full lawn. [50]
3. Progression (Cancer Grows Out of Control)
This is the stage that we “discover” that we have cancer. Prevention is over, it’s time to treat the cancer with a doctor’s prescriptions and therapy.
3. Progression (Cancer Grows Out of Control)
“Progression begins when a bunch of advanced cancer cells progress in their growth until they have done their final damage. It is like the fully-grown lawn invading everything around it: the garden, driveway and sidewalk. When the cancer takes on these deadly properties, it is considered malignant [50].”
Takeaway: There are 3 Stages of Cancer Growth
There are three stages of cancer growth: initiation, promotion, and progression.
Takeaway: There are 3 Stages of Cancer Growth
There are three stages of cancer growth: initiation, promotion, and progression.
The first and second stages are preventable. The third stage kills you.
THE CHINA STUDY: FOUR EXPERIMENTS
EXPERIMENT #1: DOES PROTEIN INTAKE AFFECT CANCER INITIATION?
Enzyme Activity
“Enzyme activity could be easily modified
simply by changing the level of protein
intake [52]”
EXPERIMENT #2: DOES PROTEIN INTAKE AFFECT CANCER PROMOTION?
EXPERIMENT #2: DOES PROTEIN INTAKE AFFECT CANCER INITIATION?
Animals fed higher-protein (20%) produced substantially more foci, while animals fed lower-protein (5%) produced substantially less foci. [56]
Foci: precursor clusters of cells that grow into
tumors. Although most foci do not become
full-blown tumor cells, they are predictive of
tumor development. [54]
“One idea seemed to be clear: lower protein intake dramatically decreased tumor
initiation [53]”
EXPERIMENT #3
WHICH WOULD CAUSE MORE CANCER GROWTH?
VS.
The experiment here showed that a higher dose of Aflatoxin (remember that’s the carcinogen), and a lower protein intake, resulted in lower foci (tumor clusters).
A SIGNIFICANT FINDING
Foci developed only when the animals met or exceeded the amount of protein (12%) needed to satisfy their body growth rate. That is, when the animals met and surpassed their requirements for protein, disease onset began [58].
THE BODY HAS A OPTIMUM % OF PROTEIN IT NEEDS
The body has a sweet spot for how much protein it needs
10% 12% 15%
The body has a sweet spot for how much protein it needs
3 ounces of meat (21 grams)
What 10% Animal Protein Looks Like
1 Yogurt (11 grams) 1 Glass of Milk (8 grams)
THE BIG PAYOFF
“For all of the experiments so far, T Colin Campbell was using casein (mostly protein from cow’s milk) as the main protein he was testing.
So the next logical question… was whether plant protein (as opposed to animal protein), tested in the same way, has the same effect on cancer as
casein [59].”
Does plant protein affect cancer initiation and promotion?
NO. IT DIDN’T
Does plant protein affect cancer initiation and promotion?
“Gluten, the protein of wheat, did not produce the same result as casein, even when fed at the same 20% level. [59]”
The main takeaway: Nutrients from animal-based foods increased tumor development while nutrients from plant-based foods decreased tumor development.
FOOD IS MEDICINE?
WILL YOU GET CANCER
FROM SMOKING?
MORE LIKELY
BUT NOT 100%
HOW DOES THE CHINA STUDY RECOMMEND I EAT
FOOD IS MEDICINE
ONE SENTENCE “Eat a whole food, plant-based diet , while
minimizing the consumption of refined
foods, added salt and added fats.”
3 SMALL STEPS
1. Eat Plants: eat the rainbow, as many colors as close to their natural state as possible
2. Eat less animal protein: less meat, fish, eggs and milk
3. Avoid processed foods: less sugars, starchy carbohydrates and vitamin supplement
GIVE IT ONE MONTH
1. You’ll discover new foods
2. You’ll feel better
3. You’ll find it’s easier than you thought.
