If roundworms sense that food is abundant, their metabolism adjusts accordingly. Their bodies respond to promote rapid ingestion, rapid growth and rapid aging, Kornfeld explains. In contrast, when the worms sense a shortage of food, they make “metabolic decisions” to delay growth, delay energy use and extend lifespan.
Brown University ecologist Marc Tatar says the current study, published in this week's Science, provides "really profound evidence" that longevity is controlled not by actual resources but rather by hormones that are cued to resources (such as the way plants sense winter by sunlight changes). "It's like the whole system doesn't actually function on the currency of resources anymore, it all functions on virtual data about what the resources should be like," he says. "It's mind over matter."
In April, the United States Centers for Disease Control and Prevention released a study challenging the conventional wisdom that eating less promotes longevity. The study found that the very thin run roughly the same risk of early death as the overweight. And now the tide seems to be turning against a common explanation for the long-standing observation that restricting food in lab organisms from yeast to mice prolongs life.
As regards the comment re AGEs in soups/broths, that's meaningless as peoples' diets nowadays include a vast range of foods, not just broths/soups, and I doubt that even hunter-gatherer tribes soley ate broths and soups for their cooked-foods - indeed, they ate plenty of
meats cooked without water on spits.
As regards the raw/cooked issue, I made a good point, there. Very few people mix cooked and raw at the same meal, nowadays. The average restaurant meal will feature cooked meat and cooked veg, with a dessert involving pasteurised dairy or some such. Only rarely will people nowadays include a bit of raw fruit or raw veg at the same meal.
OK, first of all, let's examine BYV's notion that since all human cultures eat (some) cooked-food and that that implies that we need it or have to have it. This is a false conclusion as the only way one could conclude that cooked-food is essential/necessary for human health and that raw food is unnecessary or toxic is if we could encounter a human culture that only ate cooked-food and no raw food whatsoever (no such culture exists, to my knowledge as all humans need to eat raw fruit for vitamin C etc., and the Eskimos on their 99% meat diets would eat some of their meats raw, also for the vitamin C among other nutrients) . I should also point out that since all non-human species do not cook their foods and thrive in that state, that humans don't need to cook their food, either.There has not been an all Vegan Civilization either, but that's not stopping them from believing meat is necessary in Man's diet. Many claim to be thriving as you do. I don't think BYV's conclusion is false by any means. I think merely, it is their own conclusion and not yours.
Re BYV's mention of Maillard molecules in stored, raw food:- This is an exaggeration as the Maillard molecules in raw food are never anywhere near as high as those in cooked-foods.After reading Jeff Novick's list, it appears your comment might not be true. Unless you can fins a different list- which I wouldn't mind seeing by the way. The raw Avocado was more than a boiled potato. Obviously it might be good to track down the origin of that list.
The claim that cooking either reduces or doesn't affect the allergenicity of food seems to be misguided. Here's a relevant quotation from the Wikipedia entry for AGEs:- Advanced Gycation End Products. This article is backed up by a reference to a study:- "AGEs may be less, or more, reactive than the initial sugars they were formed from. Foods may be up to 200 times more immunoreactive after cooking". This would seem to imply that allergenicity is worse as regards cooked-foods than the raw version.
The only genuine statement that BYV makes here is that eating some raw food (10% apparently) along with the cooked-food minimises the leukocytosis reaction. But since most people nowadays in the Western world don't automatically eat raw and cooked food at the same meal, this is meaningless.This is hardly meaningless if one eats 30-50% raw/cooked. And how can you make the blanket statement that 'MOST' people don't eat raw and cooked at the same meal... ehh, okay don't answer that... but it is not meaningless! If people are uneducated about the issue, of course they won't know what they are doing is wrong. And why is that? Because, ehh OH FRAK! It's complicated. This Family raises that Family- God help me like the Bear said- Acculturation is a mighty force. And if you have read him, you'll know he says most will fail because of Acculturation. I detest people who tell people they will fail. It is not constructive. It is very possible that there are people eating raw and cooked and many are over at McDougall... and with out the meat heh heh.
I'm impressed by your efforts so far, incidentally - at least it hasn't been boring.Thank you, I think. Maybe that's because I'm not anti-raw at all.
Cooking can be beneficial.
In many cases, cooking destroys some of the harmful anti-nutrients that bind minerals in the gut and interfere with the utilization of nutrients. Destruction of these anti-nutrients increases absorption. Steaming vegetables and making vegetable soups breaks down cellulose and alters the plants’ cell structures so that fewer of your own enzymes are needed to digest the food, not more. The point is that this “cooked food is dead food” enzyme argument does not hold water. On the other hand, the roasting of nuts and the baking of cereals does reduce availability and absorbability of protein.
Even at face value, Kouchakoff experiments not an argument against cooked food when some raw foods are also eaten. However, for the sake of discussion, let's look at the Kouchakoff experiments upon which the raw-foodist claims are based. When we do, what we first notice is that Kouchakoff's experiments are not an argument against predominantly raw diets (versus 100% raw)--or even against predominantly cooked diets that include sufficient amounts of raw food--since according to Kouchakoff [1930]:
It has been proved possible to take, without changing the blood formula, every kind of foodstuff which is habitually eaten now, but only by following this rule, viz.--that it must be taken along with raw products, according to a definite formula.

As you can see, it is not the unrefined unprocessed starchy foods, like a potato, a sweet potato, or a bowl of oatmeal, let alone a slice of whole wheat bread that is contributing to the AGE load of most people. The real culprits to the high level of AGE's in the American diet are the high fat foods, fried foods and animal products that most Americans cosnume.
According to Dr. Stephen Cunnane it was a rich and secure shore-based diet that fuelled and provided the essential nutrients to make our brains what they are today. Controversially, according to Dr. Cunnane our initial brain boost didn't happen by adaptation, but by exaptation, or chance.
Secondly, it's pretty clear that you won't accept any evidence no matter how many scientific papers I show you re Advanced glycation end products, links to diabetes etc.. Fair enough, but the evidence is there, regardless, and most responsible nutritionists, as a result of such a multitude of studies, already recommend against extreme forms of cooking such as grilling/frying/microwaving/baking so that already 1/2 to 2/3 of the pro-cooking argument is already lost.Some believe some of this AGE business to be a natural reaction. Perhaps as- I repeat again, we go too far. I agree that grilling and frying and baking are quite possibly a bad thing. You have shown me no scientific evidence regarding Soups and Broths. And the Salmon Soup I posted never reached the boiling point.
Exposure to advanced glycation end products
Another reason why typical vegetarian diets are not ideal for diabetics is they are not designed to avoid exposure to advanced glycation end products (AGEs). There is a huge body of literature documenting that the high sugar in the bloodstream in diabetics promotes the formation of AGEs in the body as the sugars react with body proteins. The formation of advanced glycation end products (AGEs) on connective tissue and within cells stiffens and ages your blood vessels and accelerates aging throughout the body. AGEs are a significant causal factor of the horrible side effects of diabetes, such as blindness, kidney failure, heart attacks, and strokes.The chemical modifications of cells that occur as a result of the accumulation of AGEs are one of the primary hallmarks of aged and diseased tissues.
But the accumulation of AGEs in the body does not result solely from increased sugar in the bloodstream. AGEs also are formed when starchy foods are cooked at higher temperatures, causing molecular rearrangement. Acrylamides are an example of AGEs that occur from cooking carbohydrates—such as potatoes and grains—in the absence of water. The higher the temperature, the more these toxic compounds are formed. Neither acrylamides nor other AGEs are formed when vegetables are steamed or cooked in soups.
The frightening new news is that eating foods with these advanced glycation products raises blood and tissue levels and increases nerve damage. Cooking with water prevents sugars from binding to proteins to form these poisonous chemicals. Cooking without water causes sugars to combine with proteins to form these advanced glycation products. So, baking, roasting and broiling cause the poisonous advanced glycation products to form, while boiling and steaming prevent them.
Among raw-food enthusiasts, there is a very popular myth that enzymes are "alive" and these so-called "living enzymes" somehow (never supported with biochemistry) assist the body in digesting food.
There is also a myth that foods are "alive" and therefore contain "living enzymes". Well, foods are rendered quite dead upon chewing, and certainly the food's being digested would also certainly kill any living cell that was not killed by chewing. If you think that foods are alive, then chew some seeds and plant the mush thus prepared, and wait for it to sprout and grow - does anyone really believe chewed foods can be "alive".
As for the age of 102, that's meaningless as plenty of people, in ill-health or otherwise, have lived till 120 or so. It could also be argued that if one at all-rawpalaeo from birth that one could live till 150.Argued for sure as it hasn't happened yet. And in favor of Cornaro, he wasn't in ill health. Actually he was in ill health at 40, changed his ways and lived a very healthy life. If you live a very healthy life to 102, I think that will be just grand. I hope you do.
Re broths/soups comment:- That's pretty clear. I mean, there were plenty of populations in ill-health such as the Egyptians who used broths, so it's unlikely that broths are such useful food. The only factors that Weston-Price noted were that the healthiest tribes both ate high amounts of animal food and also ate some of their food(animal and plant-based) raw.It's not clear at all. It may be clear to you, in your head and that's fine, but it's not clear at all and your argument that the Egyptians were ill because of broth is almost laughable. Scratch almost. I'm sorry but it's true. If you picked a particular broth- say cream of toad soup I'd have to look into it before responding.
