Dear Future Centenarian,
For millions of years, we subsisted on a hunter/gatherer diet. That means we ate what we could find and kill. Those diets were actually much more diverse than typical modern diets. Average life spans were quite short due to the harshness and dangers of everyday life. But contrary to popular belief, maximum life spans may have been much longer than we can hope to reach today. And diseases associated with aging were largely unknown.
Around 10,000 years ago, we entered the Agricultural Age. We started growing crops and domesticating animals. That’s when we started eating grains, and later, dairy products, and we were not adapted to them.
We’re not adapted to agricultural diets now either, because 10,000 years is nothing on the human evolutionary scale. We are still adapted to the hunter/gatherer diet. We’ve been on it for millions of years. We’re also adapted to eating cooked meat and some vegetables, since we’ve been eating those for well over a million years.
By eliminating ALL grains and dairy products from your diet and by being physically active, you may be able to avoid most of the aging-related diseases. The sky is not the limit, but you could slow aging dramatically and may be able to add lots of healthy active years to your life. Find out more by reading Food and Western Disease by Staffan Lindeberg. This may be the single most important book you will ever read, if your goal is extreme longevity. If you’re young now, there is no need to eat this way until you are well over thirty. In fact, it could be counter-productive for children, since adaptation to recent changes drops drastically as we age.
Most of the seven habits I describe in Life Extension Express can be fairly easy to implement once you grasp the incredible benefits. In fact, they can even be fun, especially once you experience the results. I thought this one would take lots of will power though, at least for me.
I enjoy a cup of chocolate ice cream every month or so, and I do like cheese. There are fairly good healthy alternatives, even though they’re not quite the same. And although I seldom touch bread, I thought it would be tough to figure out how to replace my oatmeal and whole grain cereals. Well, I was wrong. I even found grainless alternatives to both bread and cereals. For example, you can get ones made from sunflower seeds. See www.LydiasOrganic.com for some tasty substitutes.
The web is full of recipes for grain-free breads, cereals and pancakes as well as sources and recipes for non-dairy cheeses. And who needs dairy when you can enjoy delicious and nutritious almond milk?
Sure, a hunter/gatherer diet is not as convenient, especially when you dine out. And it does take some trial and error and more creative grocery shopping. So the question you might ask yourself is, “Is it worth it”?
The answer is a no-brainer for me. “Yes”! Why? Because it positions you and me better to take advantage of the emerging age-reversal and repair technologies described in Part I of Life Extension Express by extending our average lifespans now. In fact, this may be the greatest life-extender of them all. And yummies like honey, cacao, and avocado, or plants like them, have probably been in our diet for millions of years, so we are not talking total self-denial.
There’s an additional benefit too, if weight loss is your goal. It’s next to impossible to be overweight if you adopt a hunter/gatherer lifestyle for a protracted period of time.
Long Life,
David Kekich

REGENERATIVE HEALING OF CAVITIES IN TEETH
The dental application of regenerative medicine is one of the more advanced areas in this field of research. Whole teeth have been grown from stem cells in animal studies, and here scientists demonstrate healing of cavities by regrowth of tooth enamel. After about one month, the cavities had disappeared.

INDUCED PLURIPOTENT STEM CELLS FROM BLOOD (July 02 2010) http://www.longevitymeme.org/news/vnl.cfm?id=4795
From Wired: “Blood drawn with a simple needle stick can be coaxed into producing stem cells that may have the ability to form any type of tissue in the body, three independent papers report. The new technique will allow scientists to tap a large, readily available source of personalized stem cells. Because taking blood is safe, fast and efficient compared to current stem cell harvesting methods, some of which include biopsies and pretreatments with drugs, researchers hope that blood-derived stem cells could one day be used to study and treat diseases. Three research groups used similar methods to prod certain immune cells in human blood to become induced pluripotent stem cells. Because they are reprogrammed adult cells, these stem cells share many of the same regenerative abilities as true embryonic stem cells but may not have as much versatility. Scientists’ manipulations turned the stem cells in the new studies into several types of mature blood cells, including infection-fighting T cells. What’s more, all the groups showed that a batch of the stem cells implanted into mice developed into the three main types of progenitor cells found in human embryos.”
IMPROVED ASSOCIATION OF LONGEVITY GENES WITH LONGEVITY (July 02 2010) http://www.longevitymeme.org/news/vnl.cfm?id=4794
Via ScienceNews: “In the new study, researchers looked at genetic markers called single nucleotide polymorphisms, or SNPs, in 1,055 centenarians and 1,267 younger people, all of European descent. The scientists found 150 genetic SNP variants linked to extreme longevity. Initially, the team identified only 33 SNPs found more often in people aged 90 to 114 years but not in a control group made up of people who will presumably live an average lifespan. Biostatistician Paola Sebastiani [devised] a different statistical method to identify additional SNPs that would improve the team’s ability to predict longevity. The team tested their predictions on a separate group of centenarians and controls. With the 150 SNPs, the researchers could correctly predict who was a centenarian 77 percent of the time. Now on one side, 77 percent is a very high accuracy for a genetic model, which means that the traits that we are looking at have a very strong genetic base. On the other hand, the 150 SNPs can’t explain why the remaining 23 percent of centenarians in the study have reached such ripe old ages. It could mean that those people have other, rare genetic variants or lifestyles responsible for their longevity or some combination of the two.”
ORGANS MADE TO ORDER (July 01 2010) http://www.longevitymeme.org/news/vnl.cfm?id=4793
As the Smithsonian notes, “It won’t be long before surgeons routinely install replacement body parts created in the laboratory. Anthony Atala works in the body shop of the future. He and his colleagues use human cells to grow muscles, blood vessels, skin and even a complete urinary bladder. Much of the work is experimental and hasn’t yet been tested in human patients, but Atala has implanted laboratory-grown bladders into more than two dozen children and young adults born with defective bladders that don’t empty properly, a condition that can cause kidney damage. The bladders were the first lab-generated human organs implanted in people. If they continue to perform well in clinical tests, the treatment may become standard not only for birth defects of the bladder but also for bladder cancer and other conditions. Regenerative medicine’s once-wild ideas are fast becoming reality. Late last year, Organovo, a biotech company in San Diego, began distributing the first commercially available body-part printer. Yes, you read correctly: a printer for body parts. Using the same idea as an ink-jet printer, it jets laser-guided droplets of cells and scaffold material onto a movable platform. With each pass of the printer head, the platform sinks, and the deposited material gradually builds up a 3-D piece of tissue. Regenerative medicine laboratories around the world have relied on the printer to generate pieces of skin, muscle and blood vessels. Atala’s lab has used the technology to construct a two-chambered mouse-size heart in about 40 minutes.”
ARE OLD STEM CELLS LESS USEFUL? (June 30 2010)
http://www.longevitymeme.org/news/vnl.cfm?id=4791
Researchers are gathering evidence to suggest that stem cells from the old are less useful when transplanted – which means that some form of repair or other manipulations may need to be included in future stem cell therapies for the degenerative conditions of aging: “Clinical trials of cardiac cell therapy have indicated limited benefits in aging patients, even though preclinical studies using young animals consistently reported significant improvements. Animal studies have demonstrated reduced efficacy of donor cells isolated from older individuals. Here, we evaluated the effects of donor age on the function of human mesenchymal stem cells (hMSCs) in the context of cell therapy for ischemic cardiomyopathy. The regenerative capacity of hMSCs was significantly influenced by age. Transplanting young hMSCs improved functional outcomes after an MI by preventing matrix degradation and promoting angiogenesis. The clinical implication is that aged patients require an optimized source of stem cells for treatment.”
NOTE: There may be a solution on the horizon.
PROGRESS TOWARDS UNDERSTANDING MEMORY (June 29 2010) http://www.longevitymeme.org/news/vnl.cfm?id=4789
Understanding the physical basis of human memory will enable therapies to both enhance youthful memory and reverse its decline with age. From ScienceDaily, an example of present investigations into the biology of memory: “We found one of the key proteins involved in the process of memory and learning. This protein is present in the part of the brain in which memories are stored. We have found that in order for any memory to be laid down this protein, called the M3-muscarinic receptor, has to be activated. We have also determined that this protein undergoes a very specific change during the formation of a memory – and that this change is an essential part of memory formation. In this regard our study reveals at least one of the molecular mechanisms that are operating in the brain when we form a memory and as such this represents a major break through in our understanding of how we lay down memories. This finding is not only interesting in its own right but has important clinical implications. One of the major symptoms of Alzheimer’s disease is memory loss. Our study identifies one of the key processes involved in memory and learning and we state in the paper that drugs designed to target the protein identified in our study would be of benefit in treating Alzheimer’s disease.”
MORE ON OVARIES AND LONGEVITY IN MICE (June 29 2010) http://www.longevitymeme.org/news/vnl.cfm?id=4788
Another study to show that transplanting young ovaries into old mice extends life quite significantly: “successful ovarian transplants increased the lifespan of the mice by more than 40%. All the mice in both experiments that had received transplants resumed the normal reproductive behavior of young mice. They showed interest in male mice, mated and some had pups. Normally, old mice stay in the corner of the cage and don’t move much, but the activity of mice that had had ovarian transplants was transformed into that of younger mice and they resumed quick movements. Furthermore, the lifespan of the mice who received young ovaries was much longer than that of the control mice: the mice that had received two ovaries lived for an average of 915 days, and the mice that had received one ovary, for an average of 877 days. The newest of our data show the life span of mice that received transplants of young ovaries was increased by more than 40%. The average normal lifespan for this particular breed of mice [is] 548 days. It was not known why the ovarian transplant increased the lifespan of the mice, but it might be because the transplants were prompting the continuation of normal hormonal functions.”
MORE DECELLULARIZED LUNGS DEMONSTRATED (June 28 2010) http://www.longevitymeme.org/news/vnl.cfm?id=4787
Following on from a demonstration of decellularized rat lungs, another team has produced similar work: “Researchers have been able to create tiny mouse lungs in the lab that are able to breathe. The lungs were created with stem cells and attached to a ventilator. They used a technique called decellularization, similar to the method used to create a beating mouse heart in a different lab at the University of Minnesota in 2008. In the cancer center, they took a mouse lung and stripped away all its cells. Then, injected the natural framework with stem cells. At first they used fetal mouse lung cells, but this year they had another breakthrough using adult stem cells called ‘induced pluriopotent stem cells.’ That’s basically a cell that we can take from anybody and re-program to act like an embryonic stem cell. The hope is one day human lungs could be re-created for transplant with a greater chance of success. Right now, there is no tissue matching for lung transplants. The beauty of that is that you can then create a tissue for an organ that’s transplantable that is derived from the patient and therefore would not be recognized as foreign by the immune system and not rejected. By adding the ventilator to make the lungs breathe, the stem cells are further trained to act like lung cells. It’s a huge success considering lungs are such complicated organs with some 60 different kinds of cells.”
