The document discusses The China Study, a large nutritional study that examined the relationship between diet and the risk of disease. It summarizes the study's key findings, including that consuming a plant-based, whole foods diet low in animal protein was associated with reduced cancer risk, while diets higher in animal protein increased cancer initiation and promotion. The study involved over 6,500 people in China over 20 years and its findings suggest food is medicine and that a plant-based diet can help prevent cancer growth and progression.

20. HOW FOOD GROWS CANCER

21. The Three Stages of Cancer Growth
1. Seeds
2. Grow
3. Out of Control

22. 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.

23. 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.”

24. 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]

25. 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.

26. 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].”

27. Takeaway: There are 3 Stages of Cancer Growth
There are three stages of cancer
growth: initiation, promotion, and
progression.

28. 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.

29. THE CHINA STUDY:
FOUR EXPERIMENTS

30. EXPERIMENT #1: DOES PROTEIN INTAKE
AFFECT CANCER INITIATION?

33. Enzyme Activity

34. “Enzyme activity could be easily modified
simply by changing the level of protein
intake [52]”

35. EXPERIMENT #2: DOES PROTEIN INTAKE
AFFECT CANCER PROMOTION?

36. 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]

38. 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]

39. “One idea seemed to be clear: lower protein
intake dramatically decreased tumor
initiation [53]”

40. EXPERIMENT #3
WHICH WOULD CAUSE MORE CANCER GROWTH?
VS.

42. 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).

43. A SIGNIFICANT
FINDING

45. 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].

46. THE BODY HAS A OPTIMUM % OF
PROTEIN IT NEEDS

47. The body has a sweet spot for how much protein it needs

48. 10% 12% 15%
The body has a sweet spot for how much protein it needs

49. 3 ounces of meat (21 grams)
What 10% Animal Protein Looks Like
1 Yogurt (11 grams) 1 Glass of Milk (8 grams)

50. THE BIG PAYOFF

51. “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].”

54. Does plant protein affect cancer initiation and promotion?

55. NO. IT DIDN’T
Does plant protein affect cancer initiation and promotion?

56. “Gluten, the protein of wheat, did not produce the same result as casein,
even when fed at the same 20% level. [59]”

57. The main takeaway: Nutrients from animal-based foods increased tumor
development while nutrients from plant-based foods decreased tumor
development.

58. FOOD IS MEDICINE?

60. WILL YOU GET CANCER
FROM SMOKING?

61. MORE LIKELY
BUT NOT 100%

62. HOW DOES THE
CHINA STUDY
RECOMMEND I EAT

63. FOOD IS MEDICINE

64. ONE SENTENCE
“Eat a whole food, plant-based diet , while
minimizing the consumption of refined
foods, added salt and added fats.”

65. 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

66. GIVE IT ONE MONTH

67. 1. You’ll discover new foods
2. You’ll feel better
3. You’ll find it’s easier than you thought.
