💔 Global Health Crisis: Preventable Chronic Diseases

The speaker addresses the global spread of chronic diseases like cardiovascular disease, diabetes, and hypertension, which are largely preventable through lifestyle and dietary changes. They highlight the rapid increase in these diseases, particularly in regions that have adopted Western dietary habits, leading to a significant rise in health issues and mortality rates. The speaker emphasizes the importance of preventive medicine on a global scale and the potential for reversing these trends.

🌍 The Impact of Western Lifestyle on Global Health

This paragraph discusses the globalization of illness, where non-Western populations are adopting Western lifestyles and subsequently experiencing increased rates of heart disease, obesity, and diabetes. The speaker points out the alarming transformation of certain regions, which have shifted from having low to high rates of these diseases within a single generation. The paragraph also underscores the critical opportunity to make a significant positive impact on global health through preventive measures.

🛑 The Reversible Nature of Chronic Diseases

The speaker presents evidence that heart and blood vessel diseases, which are the leading cause of death worldwide, are not only preventable but also reversible. They discuss their research and findings over the past 29 years, which demonstrate that changes in diet and lifestyle can halt or reverse the progression of diseases like prostate cancer. The paragraph includes the mention of high-tech methods used to prove the effectiveness of simple and low-cost interventions.

📉 The Alarming Rise of Obesity and Diabetes

This paragraph focuses on the epidemic of obesity, which affects two-thirds of adults and 15% of children, with a 70% increase in diabetes over the past decade. The speaker expresses concern that the current generation may be the first to experience a shorter lifespan than their parents due to these health issues. They provide data from the CDC website to illustrate the growing problem of obesity in the United States, year by year.

Transcripts

with uh all the legitimate concerns

about AIDS and Aven flu and we'll hear

about that from the brilliant Dr

brilliant later today I want to talk

about the other pandemic which is uh

cardiovascular disease diabetes

hypertension all of which are completely

preventable for at least 95% of people

just by changing diet and lifestyle

and what's happening is that there's a

globalization of illness occurring that

people are starting to eat like us and

live like us and die like us and in one

generation for example as has gone from

having one of the lowest rates of heart

disease and obesity and diabetes to one

of the highest and in Africa uh

cardiovascular disease equals the HIV

and AIDS deaths in most countries so

there's a critical window of opportunity

we have to make an important difference

that can affect the lives of literally

millions of people and practice

preventive medicine on a global scale

heart and blood vessel diseases still

kill more people not only in this

country but also worldwide than

everything else combined and yet it's

completely preventable for almost

everybody it's not only preventable it's

actually reversible and for the last

Almost 29 years we've been able to show

that by simply changing diet in

lifestyle using these very high-tech

expensive state-of-the-art measures to

prove how powerful these very simple and

low Tech and lowcost interventions can

be like quantitative arteriography

before and after a year and cardiac pet

scans we showed a few months ago we

published the first study showing that

you can actually stop or reverse the

progression of prostate cancer by making

changes in diet and lifestyle and

70% regression in the tumor growth or

inhibition of the tumor growth compared

to only 9% in the control group and in

the MRI and the Mr spectroscopy here the

prostate tumor activity is shown in red

you can see it diminishing after a year

now there is an epidemic of obesity uh

two-thirds of adults and 15% of kids

what's really concerning to me is that

diabetes has increased 70% in the past

10 years and this may be the first

generation in which our kids live a

shorter lifespan than we do that's

pitiful and it's preventable now these

are not election returns these are the

people uh the number of people who are

obese by state beginning in ' 85 86 87

these are from the CDC website 88 8889

90 91 you get a new category 92 93 94 95

96 97 98 99 2000 2001 it gets worse

we're kind of devolving

um now what can we do about this well

you know the diet that we found that can

reverse heart disease and cancer is an

Asian diet but the people in Asia are

starting to eat like we are which is why

they're starting to get sick like we are

so I've been working with a lot of the

big food companies they can make it fun

and sexy and hip and crunchy and

convenient to eat healthier foods like I

chare the uh advisory boards in

McDonald's and PepsiCo and ConAgra and

Safeway and soon Delonte and they're

finding that it's good business the

salads that you see at McDonald's came

from the work they're going to have

Asian salad a Pepsi 2third of the

revenue growth came from their better

foods and so if we can do that then we

can free up resources for buying drugs

that you really do need for treating

AIDS and HIV and malaria and for

preventing Aven flu thank you
