Question about Michael Greger, M.D.

Denis

Jedi Master
I recently had a discussion on youtube with one person who is a vegan by choice. They gave me those links where this guy (Michael Greger) who is an advocate of veganism claims that low level fat, low protein diet is "the way to go". Well, i'm not so convinced. Here are some links where he claims that cutting off meat consumption and saturated fat reduces cancer progression in patients: http://nutritionfacts.org/video/saturated-fat-cancer-progression-2/

They also gave me these links:
http://nutritionfacts.org/video/the-saturated-fat-studies-buttering-up-the-public/
http://nutritionfacts.org/video/lipotoxicity-how-saturated-fat-raises-blood-sugar/
http://nutritionfacts.org/video/good-great-bad-killer-fats/
http://nutritionfacts.org/video/optimal-cholesterol-level/

Um, afaik cancer cells survive on glucose, not saturated fats right? Also, i don't hear him mention the "good" HDL cholesterol, only LDL, "the bad one" (when too high).

What do you guys think of this guy? Is there any credibility to his claims?
 
Hello Denis, here in the forum there is access to many articles about the benefits of a diet high in fats, and proteins moderate (ketogenic diet) on page sott find a world of information about the myths of cholesterol, also benefits the ketogenic diet in people with cancer, I think I would not spend energies to enter into discussion with people who decided to be vegan, all you would do is share some links on the articles in which he talks about the benefits of a ketogenic diet, is choice of everyone take charge of your health.

if you have not had a chance to read the health issues here in the forum this is a start: :)

Thanks for the link, riclapaz.

Oh! and don't worry, i'm not wasting my energy in my discussion with them. I deliberately engaged them to exchange ideas and in order to understand them better (their train of thought, why they do what they do and so on) - i'm trying my best to bridge the differences among other people so we can all work towards common good.
 
Thanks for all the links, RedFox. I've watched Lierre Keith's video on Vegetarian Myth before, but it doesn't hurt repeating. :)

They say that the argument that vegans cause more animal deaths through agriculture has been debunked: "more crops are grown and harvested for lifestock, so in that way more animals are still killed for an omnivore lifestyle. Also many vegans dont necessarily eat more crops than some omnivores". And then they gave me this link: http://www.theflamingvegan.com/view-post/Vegan-Mythbusting-1-Are-wild-animals-killed-when-grain-is-harvested-for-vegans

Yes, that is right. From what I have read about the metabolic theory of cancer, cancerous cells primarily use fermentation of sugar and amino acids (proteins) as their energy producing mechanism. The fermentation process does not require oxygen, and is considered to be an evolutionarily older process with lower complexity. In contrast healthy cells primarily use oxygen driven metabolic process to generate energy. The metabolic theory posits that cells which are damaged or defective in a way that they cannot use the normal oxygen driven method of producing energy and do not die off naturally can become cancerous.

Since cancer cells are abnormal in their metabolism, one suggested way to make them die is to restrict the material needed for their survival. Both sugar and protein act as material for fermentation - hence calorie restriction and ketogenic diets rich in fat are suggested as adjunct therapy. Cancer cells cannot use ketones and fatty acids produced from fat metabolism as material for energy generation. However, the caveat is that if amounts eaten are not restricted even on a ketogenic diet, there are metabolic mechanisms in the body which can transform fatty acids into sugar. Blood glucose (end product of carb metabolism) levels have to be low for cells to use ketones (end products of fat metabolism) as the source of energy, thus starving cancer cells of their food.
 
Hey guys. The person i'm having a discussion with replied with this copied text from the Mayo Clinic web site, about the "myth" that sugar causes cancer to grow faster:

"Myth: People with cancer shouldn't eat sugar, since it can cause cancer to grow faster.

Fact: Sugar doesn't make cancer grow faster. All cells, including cancer cells, depend on blood sugar (glucose) for energy. But giving more sugar to cancer cells doesn't speed their growth. Likewise, depriving cancer cells of sugar doesn't slow their growth.

This misconception may be based in part on a misunderstanding of positron emission tomography (PET) scans, which use a small amount of radioactive tracer — typically a form of glucose. All tissues in your body absorb some of this tracer, but tissues that are using more energy — including cancer cells — absorb greater amounts. For this reason, some people have concluded that cancer cells grow faster on sugar. But this isn't true.

However, there is some evidence that consuming large amounts of sugar is associated with an increased risk of certain cancers, including esophageal cancer. It can also lead to weight gain and increase the risk of obesity and diabetes, which may increase the risk of cancer. http://www.mayoclinic.org/diseases-conditions/cancer/in-depth/cancer-causes/art-20044714?pg=2 "

Are the people in Mayo Clinic deliberately lying or what??

Also, they say: "Meat, protein and fat rich food causes the biggest insuline spike. Also tends to rise IGF-1 which is one of the causes of cancer as well. + high in methionine which also causes cancer (http://nutritionfacts.org/video/starving-cancer-with-methionine-restriction/)

Methionine causes cancer? First time i hear of this. Is there any truth to this?
 
I've never heard of ectopic fat leading to much less directly causing insulin resistance or diabetes. So I'll be investigating this further to see what exactly is being implied, and will report back when I can figure out exactly what mental gymnastics are being performed to come to this conclusion.

A quote from theflamingvegan:

But then meat eaters argue that they consume only “grass-fed beef” – cows raised on pastures, not fed on grain. “Grass-fed” beef is all the rage now. The fact of the matter is that the “grass-fed” label is nothing more than a vague, feel-good word for scamming consumers – right up there with “farm-fresh”, “pure”, “humane” and other make-believe nonsense. I’d love to talk about how “grass-fed” cows are actually raised (hint: it’s not all that different from “grain-fed” cows), and the impact this has on our environment. But that’s something for another time.

At both of the grocery stores that I've worked at the 100% grass-fed/grass-finished animals had to pass extra regulatory standards from the government plus investigations from independent organizations in order for anyone to say that the meat was such, so the 'grass-fed' label isn't always just some feel good label but can be a seal indicating the highest-quality meat available. The rest of the article is wishful thinking and willful ignorance.

Also, the Mayo Clinic is notorious for cherry-picking and out right lying. They still tout the 'saturated fat causes heart disease' banner, despite the fact that that theory has been disproved many times over and never even had a leg to stand on to begin with.
